　表示制御部２４は、通常表示画面Ａから設定情報表示画面Ｂ又はカメラ画像表示画面Ｃへの切換えに際し、基本情報群ａの表示を維持しつつ、附属情報群ｂに代えて各種設定情報ｃ又はカメラ画像ｄを表示させる。このようにすると、設定情報表示画面Ｂ又はカメラ画像表示画面Ｃへの切換え後も、基本情報を容易に確認することができ、その結果、基本情報の欠如によって作業に支障をきたすような不都合を解消することができる。しかも、基本情報群ａの表示位置や表示形態は、表示画面が切換っても大きく変わらない（略同じ）ので、基本情報を容易に確認することができる。ちなみに、各種設定情報ｃには、選別自動設定情報、こぎ深さ設定情報、ブレーキ／スピン設定情報、刈り高さ設定情報、方向自動設定情報、左右水平設定情報などが含まれている。 When switching from the normal display screen A to the setting information display screen B or the camera image display screen C, the display control unit 24 maintains the display of the basic information group a and replaces the various setting information c or A camera image d is displayed. In this way, even after switching to the setting information display screen B or the camera image display screen C, the basic information can be easily confirmed. As a result, there is a problem that the work is hindered due to the lack of the basic information. Can be resolved. Moreover, since the display position and display form of the basic information group a do not change greatly (substantially the same) even when the display screen is switched, the basic information can be easily confirmed. Incidentally, the various setting information c includes automatic selection setting information, saw depth setting information, brake / spin setting information, cutting height setting information, direction automatic setting information, left and right horizontal setting information, and the like.
　また、表示制御部２４は、液晶表示部１４の表示画面を、人為的な画面切換操作に応じて、カメラ画像表示画面Ｃから、他のカメラ画像を表示する第２のカメラ画像表示画面Ｅに切換可能となっている。そして、第２のカメラ画像表示画面Ｅでも、基本情報群ａの表示を維持しつつ、カメラ画像を他のカメラ画像に切換える。このようにすると、例えば、機体後方を撮影する安全確認用のバックカメラ画像と、オーガ排出口に取り付けられた排出位置調整用のオーガカメラ画像を必要に応じて切換表示することが可能になる。なお、このようなカメラ画像の切換えには、表示制御部２４に複数のカメラ画像を入力して切換表示する場合と、外部の切換操作具で切換えられたカメラ画像を入力して表示する場合とが含まれるものとする。 In addition, the display control unit 24 changes the display screen of the liquid crystal display unit 14 from the camera image display screen C to the second camera image display screen E that displays other camera images in response to an artificial screen switching operation. Switching is possible. Then, on the second camera image display screen E, the camera image is switched to another camera image while maintaining the display of the basic information group a. In this way, for example, a back camera image for safety confirmation for photographing the rear of the machine body and an auger camera image for adjusting the discharge position attached to the auger discharge port can be switched and displayed as necessary. Note that such camera image switching includes a case where a plurality of camera images are input to the display control unit 24 for switching display, and a case where a camera image switched by an external switching operation tool is input for display. Is included.
　また、表示制御部２４は、液晶表示部１４の表示画面を、人為的な画面切換操作に応じて、カメラ画像表示画面Ｃから、カメラ画像を拡大表示するカメラ画像拡大表示画面Ｆに切換可能となっている。そして、カメラ画像拡大表示画面Ｆでは、基本情報群ａの表示領域を縮小又は省略してカメラ画像を拡大表示させる。このようにすると、必要に応じて、カメラ画像を拡大表示することができるので、例えば、バックカメラ画像を拡大させて安全確認を容易にしたり、オーガカメラ画像を拡大させて排出位置調整の精度を高めることができる。ちなみに、カメラ画像表示画面Ｃでは、タッチ操作ボタン２５ｂの説明文が「カメラ拡大」となり、このボタンをタッチ操作することにより、カメラ画像拡大表示画面Ｆに切り換わる。また、カメラ画像拡大表示画面Ｆでは、タッチ操作ボタン２５ｂの説明文が「カメラ縮小」となり、このボタンをタッチ操作することにより、カメラ画像表示画面Ｃに戻ることができる。 Further, the display control unit 24 can switch the display screen of the liquid crystal display unit 14 from the camera image display screen C to a camera image enlargement display screen F that displays an enlarged camera image in accordance with an artificial screen switching operation. It has become. On the camera image enlargement display screen F, the display area of the basic information group a is reduced or omitted, and the camera image is enlarged and displayed. In this way, the camera image can be enlarged and displayed as necessary.For example, the back camera image can be enlarged to facilitate safety confirmation, or the auger camera image can be enlarged to increase the accuracy of the discharge position adjustment. Can be increased. Incidentally, on the camera image display screen C, the description of the touch operation button 25b is “camera enlargement”, and the camera image enlargement display screen F is switched by touching this button. Further, on the camera image enlargement display screen F, the description of the touch operation button 25b is “camera reduction”, and it is possible to return to the camera image display screen C by touching this button.
　また、表示制御部２４は、液晶表示部１４の表示画面を、人為的な画面切換操作に応じて、基本情報群ａを拡大表示するシンプル表示画面Ｄ（基本情報群拡大表示画面）に切換可能となっている。このようにすると、必要に応じて、基本情報群ａを拡大表示することができるので、例えば、附属情報ｂを必要としない非作業走行時に、基本情報の視認性を向上させることができる。 In addition, the display control unit 24 can switch the display screen of the liquid crystal display unit 14 to a simple display screen D (basic information group enlarged display screen) that enlarges and displays the basic information group a according to an artificial screen switching operation. It has become. If it does in this way, since basic information group a can be enlarged and displayed as needed, the visibility of basic information can be improved at the time of non-working traveling which does not require auxiliary information b, for example.
　つぎに、メンテナンスモードにおいて表示可能な画面及びその遷移について、図１０～図１２を参照して説明する。 Next, screens that can be displayed in the maintenance mode and transitions thereof will be described with reference to FIGS.
　表示制御部２４は、液晶表示部１４の表示画面を、人為的な画面切換操作に応じて、通常作業時に必要な情報を表示する通常表示モード（通常表示画面Ａ～Ｆ）と、メンテナンスに必要な情報を表示するメンテナンスモード（メンテナンス画面Ｇ～Ｑ）とに切換え可能とするにあたり、通常作業モードとメンテナンスモードとのいずれかを選択する初期画面Ｒを表示するとともに、この初期画面Ｒで通常作業モードが選択された後は、メンテナンスモードへの移行を規制する。このようにすると、初期画面Ｒで通常作業モードが選択された後は、メンテナンスモードへの移行が規制されるので、作業中に不用意に通常作業モードからメンテナンスモードに切り換わって作業に支障をきたす虞がない。 The display control unit 24 is necessary for maintenance in the normal display mode (normal display screens A to F) for displaying information necessary for the normal operation in accordance with an artificial screen switching operation on the display screen of the liquid crystal display unit 14. In order to be able to switch to the maintenance mode (maintenance screens G to Q) for displaying various information, the initial screen R for selecting either the normal operation mode or the maintenance mode is displayed, and the normal operation is performed on the initial screen R. After the mode is selected, the transition to the maintenance mode is restricted. In this way, after the normal work mode is selected on the initial screen R, the transition to the maintenance mode is restricted, so that the work mode may be inadvertently switched from the normal work mode to the maintenance mode during work. There is no fear of coming.
　また、表示制御部２４は、エンジン停止状態でキースイッチがＯＮした場合にのみ初期画面Ｒを表示させる。このようにすると、通常作業モードを選択した後は、エンジンの停止操作を行わない限り、通常作業モードからメンテナンスモードへの移行を禁止することができる。 Also, the display control unit 24 displays the initial screen R only when the key switch is turned on while the engine is stopped. In this manner, after the normal work mode is selected, the transition from the normal work mode to the maintenance mode can be prohibited unless the engine is stopped.
　また、表示制御部２４は、初期画面Ｒでメンテナンスモードが選択された場合、ユーザ用メンテナンス画面Ｈ～Ｌとディーラー用メンテナンス画面Ｍ～Ｑとのいずれかを選択するメンテナンスメニュートップ画面Ｇ（メンテナンス選択画面）を表示させる。このようにすると、メンテナンスモードの画面階層を深くし、ユーザーの誤操作でディーラー用メンテナンス画面Ｍ～Ｑに移行する可能性を低減することができる。以下、初期画面Ｒ及びメンテナンスモードの各画面Ｇ～Ｑについて説明する。 In addition, when the maintenance mode is selected on the initial screen R, the display control unit 24 selects a maintenance menu top screen G (maintenance selection screen) for selecting one of the user maintenance screens H to L and the dealer maintenance screens M to Q. Screen).

　つぎに、表示制御部２４の入出力及び表示制御の制御手順について、図１３及び図１４を参照して説明する。 Next, the input / output and display control procedures of the display control unit 24 will be described with reference to FIGS.
　図１３に示すように、表示制御部２４は、液晶表示部１４のタッチパネル操作信号、物理的操作ボタン２６ａ～２６ｅの操作信号、カメラ画像、センサ情報、設定情報などを入力し、これらの入力信号に基いて液晶表示部１４の表示制御を行う。 As shown in FIG. 13, the display control unit 24 inputs touch panel operation signals of the liquid crystal display unit 14, operation signals of the physical operation buttons 26a to 26e, camera images, sensor information, setting information, and the like. The display control of the liquid crystal display unit 14 is performed based on the above.
　図１４に示すように、表示制御では、まず、エンジンが停止状態であるか否かを判断するとともに（Ｓ１）、キースイッチのＯＮ操作の有無を判断し（Ｓ２）、ここで両判断の結果がいずれもＹＥＳである場合は、液晶表示部１４に初期画面Ｒを表示させる（Ｓ３）。初期画面Ｒの表示後は、モード選択操作を判断し（Ｓ４）、ここで、メンテナンスモードが選択された場合は、メンテナンスモードを実行する（Ｓ５）。メンテナンスモードの実行中は、初期画面Ｒへの戻り操作が可能であり、該戻り操作の判断（Ｓ６）に基いて初期画面Ｒを再表示させる。一方、初期画面Ｒで通常表示モードが選択された場合は、通常表示モードを実行する（Ｓ７）。そして、通常表示モードを選択した後は、初期画面Ｒへの移行が制限される。つまり、エンジン停止状態でキースイッチがＯＮした場合にのみ初期画面Ｒを表示させるので、通常作業モードを選択した後や、エンジン始動に応じて通常作業モードに移行した後は、エンジンの停止操作を行わない限り、通常作業モードからメンテナンスモードへの移行が禁止される。 As shown in FIG. 14, in the display control, first, it is determined whether or not the engine is stopped (S1), and whether or not the key switch is turned on is determined (S2). Is YES, the initial screen R is displayed on the liquid crystal display unit 14 (S3). After the initial screen R is displayed, the mode selection operation is determined (S4). If the maintenance mode is selected here, the maintenance mode is executed (S5). While the maintenance mode is being executed, a return operation to the initial screen R is possible, and the initial screen R is redisplayed based on the determination of the return operation (S6). On the other hand, when the normal display mode is selected on the initial screen R, the normal display mode is executed (S7). Then, after selecting the normal display mode, the transition to the initial screen R is restricted. In other words, since the initial screen R is displayed only when the key switch is turned on while the engine is stopped, the engine stop operation is not performed after the normal operation mode is selected or after the normal operation mode is entered in response to the engine start. Unless it is performed, the transition from the normal work mode to the maintenance mode is prohibited.
　つぎに、操縦部７に配置される操作具の詳細について、図７及び図１５～図１９を参照して説明する。 Next, details of the operation tool arranged in the control unit 7 will be described with reference to FIG. 7 and FIGS. 15 to 19.
　操縦部７に配置される操作具は、マイクロコンピュータ等から構成する電子制御装置ＥＣＵ（Electronic Control Unit）を介して機体各部の作動を制御する。或いは、機械的に連係して機体各部の作動を制御する。なお、電子制御装置ＥＣＵは、機体に複数設け、各ユニットはコントロールエリアネットワーク（ＣＡＮ）で相互通信可能に結んでいる。そして、具体的には、図１５に示すように、運転席９の前方右側寄りに機体の旋回や前処理部２の昇降を行う操作具であるマルチステアリングレバー３８を設け、マルチステアリングレバー３８の後方に、マルチステアリングレバー３８を操作する際に使用するアームレスト３９を設けている。 The operation tool arranged in the control unit 7 controls the operation of each part of the machine body through an electronic control unit ECU (Electronic Control Unit) configured by a microcomputer or the like. Alternatively, the operation of each part of the airframe is controlled by mechanically linking. A plurality of electronic control units ECU are provided in the airframe, and the units are connected to each other via a control area network (CAN). Specifically, as shown in FIG. 15, a multi-steering lever 38, which is an operation tool for turning the fuselage and raising / lowering the preprocessing unit 2, is provided near the front right side of the driver's seat 9. An armrest 39 used when operating the multi-steering lever 38 is provided on the rear side.
　マルチステアリングレバー３８は、前後・左右に揺動自在に支持され、基部に設ける操向ポテンショメータとリフト昇降ポテンショメータによって、マルチステアリングレバー３８の操作角度がＥＣＵに入力される。また、ＥＣＵは、マルチステアリングレバー３８の左右方向の傾倒を検出すると、ソレノイドバルブによって油圧シリンダを作動させ、ミッションケースのサイドクラッチを切って、方向の微調整を行う。或いは、さらなる傾倒操作を検出すると、マルチステアリングレバー３８の操作角度に応じて、走行部８の旋回方向内側となる駆動力をコントロールして旋回力を変更する。そして、マルチステアリングレバー３８の前後方向の傾倒を検出すると、油圧リフトシンダを作動させて、前処理部２をマルチステアリングレバー３８の操作角度に比例した昇降速度で昇降させる。 The multi-steering lever 38 is supported so as to be swingable back and forth and right and left, and the operation angle of the multi-steering lever 38 is input to the ECU by a steering potentiometer and a lift elevating potentiometer provided at the base. Further, when the ECU detects the tilting of the multi-steer lever 38 in the left-right direction, the hydraulic cylinder is operated by the solenoid valve, the side clutch of the transmission case is disengaged, and the direction is finely adjusted. Alternatively, when a further tilting operation is detected, the turning force is changed by controlling the driving force on the inner side in the turning direction of the traveling unit 8 according to the operation angle of the multi-steer lever 38. When the forward / backward tilt of the multi-steer lever 38 is detected, the hydraulic lift cinder is actuated to move the pre-processing unit 2 up and down at an ascending / descending speed proportional to the operation angle of the multi-steer lever 38.
　運転席９の前方左側寄りには、設定操作パネル１３が設けられる。設定操作パネル１３は、スイッチケース４２に第１の操作具群を設けて構成されている。そして、第１の操作具群は、各機能毎に線引きによって区画された樹脂シート４３の複数の領域に、操作具と必要に応じてＬＥＤ（Light Emitting Diode）ランプを配置する。なお、樹脂シート４３はスイッチケース４２に貼り付け、操作具の名称や図柄を印刷している。以下、第１の操作具群の個々の操作具について説明する。 A setting operation panel 13 is provided near the front left side of the driver's seat 9. The setting operation panel 13 is configured by providing a first operation tool group on the switch case 42. In the first operation tool group, the operation tool and, if necessary, an LED (Light-Emitting-Diode) lamp are arranged in a plurality of regions of the resin sheet 43 partitioned by drawing for each function. In addition, the resin sheet 43 is affixed on the switch case 42, and the name and design of an operation tool are printed. Hereinafter, each operation tool of the first operation tool group will be described.
　先ず、スイッチケース４２の右寄りの前部に、刈取りクラッチと脱穀クラッチを断続する操作具であるパワークラッチスイッチ４４と、その切替状態を表示するＬＥＤランプ４５を設ける。そして、パワークラッチスイッチ４４は、モーメンタリ型のシーソースイッチで構成し、スイッチ４４の前部側を押す度に脱穀クラッチ入り、刈取りクラッチ入りと切り替わり、後部側を押す度に刈取りクラッチ切り、脱穀クラッチ切りに切り替わる。なお、上記パワークラッチスイッチ４４を操作すると、ＥＣＵはクラッチモータを作動させて、ベルトテンションクラッチ方式の脱穀クラッチ、及び刈取りクラッチを断続する。 First, a power clutch switch 44, which is an operation tool for connecting and disconnecting a mowing clutch and a threshing clutch, and an LED lamp 45 for displaying the switching state are provided at the front right side of the switch case 42. The power clutch switch 44 is composed of a momentary type seesaw switch, which switches between the threshing clutch and the mowing clutch each time the front side of the switch 44 is pressed, and the mowing clutch and the threshing clutch are switched each time the rear side is pressed. Switch to When the power clutch switch 44 is operated, the ECU activates the clutch motor to connect and disconnect the belt-tension clutch type threshing clutch and the mowing clutch.
　また、スイッチケース４２の右寄りの後部に、エンジン回転数を設定する操作具であるエンジン回転自動ダイヤル４６と自動制御状態を表示するＬＥＤランプ４７を設ける。そして、エンジン回転自動ダイヤル４６は、モーメンタリ型のスイッチとボリューム（可変抵抗器）を作動させ、ダイヤル４６を押す度にスイッチがオンとなり、エンジン回転自動制御が入り・切りされる。また、ダイヤル４６によってボリュームを回転操作すると、回転角度に応じたエンジン回転数に設定される。なお、エンジン回転自動ダイヤル４６の信号に基づいてエンジンＥＣＵは、前述のエンジン回転自動制御を行い、或いはエンジン回転自動ダイヤル４６で設定したエンジン回転数になるようにエンジンを制御する。 Further, an engine rotation automatic dial 46 which is an operation tool for setting the engine speed and an LED lamp 47 for displaying an automatic control state are provided at the rear right side of the switch case 42. The engine rotation automatic dial 46 operates a momentary switch and a volume (variable resistor), and the switch is turned on each time the dial 46 is pressed, and the engine rotation automatic control is turned on / off. When the volume is rotated by the dial 46, the engine speed is set according to the rotation angle. Based on the signal from the engine rotation automatic dial 46, the engine ECU performs the engine rotation automatic control described above or controls the engine so that the engine rotation speed set by the engine rotation automatic dial 46 is obtained.
　さらに、スイッチケース４２の中央寄りの前部に、リフトシャットスイッチ４８とその状態を表示するＬＥＤランプ４９を設ける。また、スイッチケース４２の中央寄りの後部に、方向自動スイッチ５０と扱深さ自動制御を入り切りする操作具である扱深さ自動スイッチ５２、並びにそれらの状態を表示するＬＥＤランプ５１、５３を左右に併設する。そして、これらのスイッチ４８、５０、５２は何れもタクタイルスイッチで構成し、スイッチケース４２の表面に設ける樹脂シート４３の下方に設け、スイッチ４８、５０、５２への塵埃の侵入を防止している。 Further, a lift shut switch 48 and an LED lamp 49 for displaying the state thereof are provided at the front part near the center of the switch case 42. Further, at the rear part near the center of the switch case 42, the automatic direction switch 50 and the automatic operating depth switch 52, which is an operating tool for turning on and off the automatic operating depth control, and the LED lamps 51 and 53 for displaying the state thereof are provided on the left and right sides. It is attached to. These switches 48, 50, 52 are all constituted by tactile switches, and are provided below the resin sheet 43 provided on the surface of the switch case 42 to prevent dust from entering the switches 48, 50, 52. .
　なお、リフトシャットスイッチ４８は、刈取り脱穀作業時に前処理部２がリフトポテンショメータによって所定の高さまで上昇したことを検出した際に、ＥＣＵを介して刈取りクラッチを切断して、刈取部Ｂの駆動を自動的に停止させる制御を、有効、或いは無効にする切替えスイッチであり、係るリフトシャットスイッチ４８を入りにすると、一行程の穀稈を刈り終えて次行程の刈取りを行うべく前処理部２を上昇させ、その後に機体の旋回や移動走行を行う際に、前処理部２の駆動が自動的に停止するから、前処理部２の駆動振動や騒音の発生が防止される。 When the lift shut switch 48 detects that the pre-processing unit 2 has been raised to a predetermined height by the lift potentiometer during the cutting and threshing operation, the lift shut switch 48 disconnects the cutting clutch via the ECU and drives the cutting unit B. This is a changeover switch that enables or disables the control to automatically stop. When the lift shut switch 48 is turned on, the pre-processing unit 2 is used to cut the grain of one stroke and cut the next stroke. Since the drive of the pre-processing unit 2 is automatically stopped when the aircraft is turned up and then the aircraft is turned or moved, the generation of drive vibration and noise in the pre-processing unit 2 is prevented.
　また、方向自動スイッチ５０は、方向自動制御を入り切りするスイッチであり、係る方向自動制御は、刈取作物の条間に対して中央のデバイダの通過位置を方向センサで感知し、デバイダが穀稈条列に近づきすぎると、ＥＣＵがサイドクラッチを断続させて、中央のデバイダが条間の中央を通過するように機体の進行方向を制御する。さらに、扱深さ自動スイッチ５２は、扱深さ自動制御を入り切りするスイッチであり，係る扱深さ自動制御は、穀稈の搬送中途に設けたセンサで穀稈の長短を検出し、脱穀部３に供給する穀稈の扱ぎ深さが適正になるように、ＥＣＵが扱ぎ深さ搬送装置をモータで上下作動させて制御する。 The direction automatic switch 50 is a switch for turning on and off the direction automatic control. The direction automatic control senses the passing position of the central divider with respect to the interval between the cut crops by the direction sensor, and the divider detects the grain row. If it is too close to the line, the ECU will disengage the side clutch and control the direction of travel of the aircraft so that the central divider passes through the center of the strip. Furthermore, the handling depth automatic switch 52 is a switch for turning on and off the handling depth automatic control. The handling depth automatic control detects the length of the cereal with a sensor provided in the middle of the cereal transportation, and the threshing unit The ECU controls the handling depth conveying device up and down with a motor so that the handling depth of the corn straw supplied to 3 becomes appropriate.
　そして、スイッチケース４２の左寄りの前部に、機体を傾斜させる操作具である水平手動レバー５４と水平ダイヤル５５と水平自動スイッチ５６と水平自動制御状態を表示するＬＥＤランプ５７を設ける。この内、水平手動レバー５４は、前後及び左右操作自在なクロスレバースイッチで構成し、水平手動レバー５４を左又は右に操作すると、ＥＣＵは機体を左傾斜又は右傾斜させ、水平手動レバー５４を前又は後に操作すると、ＥＣＵは機体を前傾又は後傾させる。 Further, a horizontal manual lever 54, a horizontal dial 55, a horizontal automatic switch 56, and an LED lamp 57 for displaying a horizontal automatic control state, which are operating tools for tilting the airframe, are provided on the front left side of the switch case 42. Of these, the horizontal manual lever 54 is configured by a cross lever switch that can be operated forward and backward and left and right. When the horizontal manual lever 54 is operated to the left or right, the ECU tilts the aircraft to the left or right, and the horizontal manual lever 54 is When operated forward or backward, the ECU tilts the aircraft forward or backward.
　また、水平自動スイッチ５６は、タクタイルスイッチで構成し、水平自動スイッチ５６を押す度に左右水平自動制御を入り切りし、また、前後水平自動制御を入り切りする。さらに、水平ダイヤル５５は、モーメンタリ型のスイッチとボリュームを作動させ、ダイヤル５５を押すとスイッチがオンとなり、機体３の前後傾斜を基準とする機体フレームと走行部８のトラックフレームが平行となる位置に戻す（前後水平リセット）。また、水平ダイヤル５５によってボリュームを回転させると、そのボリュームの回転角度が、左右水平自動制御時の目標傾斜角度に設定される。因みに水平ダイヤル５５の中央操作位置は、機体を絶対水平に制御する位置となる。 Also, the horizontal automatic switch 56 is constituted by a tactile switch, and every time the horizontal automatic switch 56 is pressed, the horizontal horizontal automatic control is turned on and off, and the front and rear horizontal automatic control is turned on and off. Further, the horizontal dial 55 operates a momentary type switch and volume, and when the dial 55 is pressed, the switch is turned on, and the body frame with respect to the front and rear inclination of the body 3 and the track frame of the traveling unit 8 are parallel to each other. Return to (reverse / horizontal reset). Further, when the volume is rotated by the horizontal dial 55, the rotation angle of the volume is set to the target inclination angle at the time of the horizontal horizontal automatic control. Incidentally, the central operation position of the horizontal dial 55 is a position for controlling the machine body to be absolutely horizontal.
　また、スイッチケース４２の左寄りの後部に、前処理部２の下降位置を設定する操作具である刈り高さダイヤル６１を設ける。刈り高さダイヤル６１はボリュームを作動させ、その回転角度が前処理部２の下降位置の設定値となる。また、刈り高さダイヤル６１を最低よりさらに回すと、前処理部２の下降位置の設定が解除される。そして、前処理部２の下降位置の設定が解除されると、ＥＣＵは、マルチステアリングレバー３８の前後動操作によって油圧リフトシリンダを作動させて、前処理部２を自由に昇降させる。 Further, a cutting height dial 61 that is an operation tool for setting the lowered position of the preprocessing unit 2 is provided at the rear left side of the switch case 42. The cutting height dial 61 operates the volume, and the rotation angle thereof becomes the set value of the lowered position of the preprocessing unit 2. Further, when the cutting height dial 61 is further rotated from the minimum, the setting of the lowered position of the preprocessing unit 2 is cancelled. Then, when the setting of the lowering position of the preprocessing unit 2 is released, the ECU operates the hydraulic lift cylinder by the back-and-forth movement operation of the multi-steering lever 38 to freely move the preprocessing unit 2 up and down.
　しかし、前処理部２の下降位置の設定が行われている際は、ＥＣＵが刈り高さダイヤル６１で設定される設定値と刈取部Ｂの昇降位置を検出するリフトポテンショメータとの値を比較し、両者の値が一致した時に、油圧リフトシリンダ５の下降作動を停止させ、前処理部２の下降を停止させる。また、その状態で刈り高さダイヤル６１を操作して設定値を変更すると、ＥＣＵは設定値に追従させて前処理部２の昇降を行う。 However, when the lowering position of the preprocessing unit 2 is set, the ECU compares the set value set by the cutting height dial 61 with the value of the lift potentiometer that detects the lifting position of the cutting unit B. When the two values match, the lowering operation of the hydraulic lift cylinder 5 is stopped, and the lowering of the pretreatment unit 2 is stopped. In addition, when the setting value is changed by operating the cutting height dial 61 in this state, the ECU moves the preprocessing unit 2 up and down in accordance with the setting value.
　機体の走行変速を行う操作具としては、主変速レバー６２と副変速レバー６３とが設けられる。この内、主変速レバー６２は、中立（停止）の横溝６４ａと前進側の縦溝６４ｂと後進側の縦溝６４ｃを備えるガイド溝６４に挿通して、上端にグリップ６２ａを備える前後・左右回動自在な操作レバーであって、主変速レバー６２の前後動操作によって走行用の静油圧式無段変速装置（ＨＳＴ）のサーボバルブを切り替え、前後進の切替えと無段変速を行う。 A main transmission lever 62 and a sub-transmission lever 63 are provided as operating tools for performing a traveling shift of the machine body. Of these, the main transmission lever 62 is inserted into a guide groove 64 having a neutral (stopped) lateral groove 64a, a forward longitudinal groove 64b, and a backward longitudinal groove 64c, and is provided with a grip 62a at its upper end and forward / backward / left / right rotation. It is a movable control lever, and the servo valve of the hydrostatic continuously variable transmission (HST) for traveling is switched by the longitudinal movement operation of the main transmission lever 62 to perform forward / reverse switching and continuously variable transmission.
　なお、主変速レバー６２は、運転席３１から立上がって操作した場合にも、容易に操作することができるように、その前後回動操作領域（前進側と後進側に亘るガイド溝６４の領域）をできるだけ機体前方側に設定するものであって、因みに実施形態では中立の横溝６４ａが運転席９の座面先端より前方に位置するように配置する。 Note that the main transmission lever 62 has its front / rear rotation operation region (region of the guide groove 64 extending forward and backward) so that the main transmission lever 62 can be easily operated even when it is raised from the driver's seat 31 and operated. ) Is set as far as possible on the front side of the machine body, and in the embodiment, the neutral lateral groove 64a is disposed in front of the front end of the seat surface of the driver's seat 9.
　また、副変速レバー６３は、主変速レバー６２の前進側ガイド溝６４ｂの機体内方側に前後回動自在に併設し、副変速レバー６３をそのグリップ６３ａを握ってガイド溝６５ａに沿って前後動操作すると、ミッションケースに設けた歯車式副変速装置を、例えば、中立、低速、標準（中速）、走行（高速）に機械的に切り換える。また、副変速レバー６３の低速切り換え位置で左側に操作して横溝６５ｂの左端に操作すると、ミッションケースに設ける旋回力切換装置を機械的にスピンターンに切り換える。なお、副変速レバー６３の後方に、コンビネーションスイッチ６６を設ける。係るコンビネーションスイッチ６６は、ライティングスイッチとフラッシャスイッチとホーンスイッチを備える。 Further, the auxiliary transmission lever 63 is provided on the forward side guide groove 64b of the main transmission lever 62 so as to be pivotable forward and backward, and the auxiliary transmission lever 63 is held back and forth along the guide groove 65a by holding the grip 63a. When the moving operation is performed, the gear-type auxiliary transmission device provided in the transmission case is mechanically switched to, for example, neutral, low speed, standard (medium speed), and traveling (high speed). Further, when the sub-shift lever 63 is operated to the left at the low-speed switching position and operated to the left end of the lateral groove 65b, the turning force switching device provided in the transmission case is mechanically switched to the spin turn. A combination switch 66 is provided behind the auxiliary transmission lever 63. The combination switch 66 includes a lighting switch, a flasher switch, and a horn switch.
　主変速レバー６２の後方には、第２の操作具群が設けられる。第２の操作具群は、旋回モード設定ダイヤル６７と唐箕風量設定ダイヤル６８と選別ダイヤル６９とＤＰＦスイッチ７０で構成し、各操作具は操作ボックスに取り付けたカバー７１の前後方向に整列させた夫々の開口部から、操作部を突出させて設ける。そして、この内、旋回モード設定ダイヤル６７は、ボリュームを回転操作し、そのボリュームの回転角度によってＥＣＵは、ブレーキターンモード、減速ターンモード、或いはフルモードターンモードに切替えると共に、フルモードターンにおける旋回力の調整圧を設定する。 A second operating tool group is provided behind the main transmission lever 62. The second operating tool group is composed of a turning mode setting dial 67, a tang air volume setting dial 68, a selection dial 69, and a DPF switch 70, and each operating tool is arranged in the front-rear direction of a cover 71 attached to the operating box. The operating portion is provided so as to protrude from the opening. Of these, the turning mode setting dial 67 rotates the volume, and the ECU switches to the brake turn mode, the deceleration turn mode, or the full mode turn mode according to the rotation angle of the volume, and the turning force in the full mode turn. Set the adjustment pressure.
　すなわち、ミッションケース３７に設ける旋回力切換装置は、ＥＣＵの制御の基に、サイドクラッチが切断された旋回内側となる走行部８を制動させるブレーキターンと、サイドクラッチが切断された旋回内側となる走行部８を減速して外側の走行部８と同一方向に駆動する減速ターンと、減速ターン並びにブレーキターンを連続して行うフルモードターンと、サイドクラッチが切断された旋回内側となる走行部８を逆回転させるスピンターンに切換自在になす。 In other words, the turning force switching device provided in the mission case 37 has a brake turn for braking the traveling unit 8 on the inside of the turn with the side clutch disengaged and an inside of the turn with the side clutch disconnected, based on the control of the ECU. A deceleration turn that decelerates the traveling unit 8 and drives it in the same direction as the outer traveling unit 8, a full mode turn that continuously performs a deceleration turn and a brake turn, and a traveling unit 8 that is inside the turn with the side clutch disconnected. It is possible to switch to a spin turn that reversely rotates.
　従って、旋回モード設定ダイヤル６７をブレーキターン側、又は減速ターン側に最大限回転させると、ＥＣＵは旋回力切換装置をブレーキターン、又は減速ターンに切り換えるモードになり、それ以外の回転角度では、旋回力切換装置をフルモードターンに切り換えるモードとなる。また、副変速レバー６３が低速切り換え位置で左側に操作されると、ＥＣＵはこれをスイッチによって検出し、スピンターンに切り換えるモードになる。なお、上記各旋回モードにおいて、実際に旋回力切換装置が切り換えられるタイミングは、マルチステアリングレバー３８の左右方向の傾倒角度によって決定される。 Therefore, when the turning mode setting dial 67 is rotated to the brake turn side or the deceleration turn side as much as possible, the ECU enters a mode for switching the turning force switching device to the brake turn or the deceleration turn. The force switching device is switched to the full mode turn. When the sub-shift lever 63 is operated to the left at the low-speed switching position, the ECU detects this by a switch and enters a mode for switching to a spin turn. Note that the timing at which the turning force switching device is actually switched in each turning mode is determined by the tilt angle of the multi-steer lever 38 in the left-right direction.
　また、唐箕風量設定ダイヤル６８はボリュームを作動させ、そのボリュームの回転角度によって脱穀部３の唐箕ファンの風量が設定される。そして、唐箕ファンの風量が設定されると、ＥＣＵはベルト無段変速装置の割りプーリーの開度をモータによって変更し、設定された風量が得られるように制御する。また、選別ダイヤル６９は、モーメンタリ型のスイッチとボリュームを作動させ、ダイヤル６９を押す度にスイッチがオンとなり、選別自動制御が入り・切りされると共に、自動制御状態を表示するＬＥＤランプ７２が点灯、又は消灯する。また、ダイヤル６９によってボリュームを回転操作すると、選別自動制御における稲と麦等の材料条件が設定される。さらに、ＤＰＦスイッチ７０は、モーメンタリ型のスイッチによって構成し、ＤＰＦスイッチ７０をオンすると、前述のＤＰＦ再生が行われる。 Also, the air volume setting dial 68 operates the volume, and the air volume of the air fan of the threshing unit 3 is set according to the rotation angle of the volume. When the air volume of the tang fan is set, the ECU changes the opening degree of the split pulley of the belt continuously variable transmission with a motor and controls so that the set air volume can be obtained. The selection dial 69 operates a momentary switch and a volume, and the switch is turned on every time the dial 69 is pressed, and automatic selection control is turned on / off, and an LED lamp 72 that displays the automatic control state is lit. Or turn off. When the volume is rotated by the dial 69, material conditions such as rice and wheat in the automatic sorting control are set. Further, the DPF switch 70 is constituted by a momentary switch. When the DPF switch 70 is turned on, the above-described DPF regeneration is performed.
　以上、操縦部７に設ける操作具について説明したが、つぎに刈取り脱穀作業中におけるオペレータの動向について考察すると、オペレータは運転席９に座った状態で機体各部の操作を行う場合も勿論ある。しかし、畦際刈り時の前処理部２の昇降操作、回り刈り時の機体の前後進操作、条合わせ、或いは条刈り及び横刈り時の機体の方向修正操作等において、これらの操作を迅速、且つ正確に行うために、オペレータは運転席９から立ち上がる場合が多い。 The operation tool provided in the control unit 7 has been described above. Next, considering the trend of the operator during the mowing and threshing operation, the operator may naturally operate each part of the machine body while sitting in the driver's seat 9. However, these operations can be performed quickly, such as in the lifting operation of the pre-processing unit 2 at the time of edge cutting, the forward / backward movement operation of the body at the time of turning, the alignment, or the direction correction operation of the body at the time of cutting and side cutting, And in order to perform accurately, the operator often stands up from the driver's seat 9.
　また、圃場の硬軟に基づく走行部８の沈下、或いは機体の傾斜に基づく刈り高さへの対応、また、刈取り材料の倒伏、或いは草丈の長い雑草を同時に刈り取る際の対応等に当たり、オペレータは運転席９から立ち上がって、機体前方の圃場状態、或いは刈取り材料の状態を確認しながら、操作具を操作して迅速、且つ適正に対応することが要求される。 In addition, the operator is required to respond to the settlement of the traveling unit 8 based on the firmness of the field, the response to the cutting height based on the inclination of the aircraft, the fall of the cutting material, or the response when simultaneously cutting the weeds having a long height. It is required to quickly and appropriately respond by operating the operating tool while standing up from the seat 9 and confirming the state of the farm field in front of the machine body or the state of the cutting material.
　すなわち、刈取り脱穀作業時には、機体の傾斜操作（水平手動レバー５４）、或いは刈り高さ設定値の変更（刈り高さダイヤル５５）による刈り高さの調節、扱ぎ深さ自動制御の入り切り操作（扱深さ自動スイッチ５２）による扱ぎ深さの調節、畦際の刈り上げ操作に伴う刈取部３の継続的な駆動操作（リフトシャットスイッチ４８）、条刈り及び横刈りに伴う方向自動制御の入り切り操作（方向自動スイッチ５０）、エンジン負荷の増減によるエンジン回転数の調節（エンジン回転自動ダイヤル４７）、籾排出等のための圃場内移動走行時の刈取り脱穀クラッチの断続操作（パワークラッチスイッチ４４）等が求められる。 That is, at the time of mowing and threshing, the aircraft is tilted (horizontal manual lever 54), or the cutting height is adjusted by changing the cutting height setting value (cutting height dial 55). Adjusting the handling depth by the handling depth automatic switch 52), continuous driving operation of the cutting unit 3 (lift shut switch 48) in response to the cutting operation at the end of the heel, turning on and off of the automatic direction control in accordance with the cutting and side cutting Operation (direction automatic switch 50), adjustment of engine speed by increasing / decreasing engine load (engine rotation automatic dial 47), intermittent operation of cutting and threshing clutch during traveling in the field for eaves discharge (power clutch switch 44) Etc. are required.
　従って、オペレータが運転席９から立ち上がって、機体前方の圃場状態、乃至刈取り材料の状態を見ながら、或いは多少目を離した間に、操作具を迅速、且つ適正に操作して対応するためには、これらの操作具がオペレータの前方にあって、即座に手が届く位置にあることが望ましい。そこで、本発明は、係る人間工学的な見地に立って、操作具の配置箇所を決定する。また、操作具の機能によって、その操作頻度には自ずと高低差が生ずる。そこで、本発明は、コンバインを取り扱う場合に、一番長時間作業となる刈取り脱穀作業中をターゲットに、この刈取り脱穀作業中の操作具の操作頻度に基づいて、その配置箇所を最終的に決定する。 Therefore, in order to respond by operating the operating tool quickly and appropriately while the operator stands up from the driver's seat 9 and looks at the state of the farm field in front of the aircraft or the state of the cutting material, or while looking a little apart It is desirable that these operating tools are in front of the operator and are in a position where they can be reached immediately. Therefore, the present invention determines the location of the operation tool from the ergonomic viewpoint. In addition, depending on the function of the operation tool, the operation frequency naturally varies in height. Therefore, the present invention finally determines the arrangement location based on the operation frequency of the operation tool during the mowing and threshing operation, while targeting the harvesting and threshing operation that is the longest operation when handling the combine. .
　具体的には、操作具の操作頻度に基づいて、第１の操作具群と第２操作具群とに分ける。そして、運転席９の側方前部に、刈取り脱穀作業中に使用する操作頻度の高い第１の操作具群を配置する。これにより、オペレータが運転席９から立ち上がって前方を注視しながら刈取り脱穀作業を行っている際、第１の操作具群はオペレータの前方に位置して、右手でマルチステアリングレバー３８を握って機体の方向修正等を行っている時でも、第１の操作具群の操作具に左手を伸ばして、これを操作することができ、迅速な対応が可能となる。 Specifically, based on the operation frequency of the operation tool, it is divided into a first operation tool group and a second operation tool group. And the 1st operation tool group with high operation frequency used during the cutting and threshing work is arrange | positioned in the side front part of the driver's seat 9. FIG. Thus, when the operator stands up from the driver's seat 9 and performs the harvesting and threshing work while gazing at the front, the first operating tool group is positioned in front of the operator and holds the multi-steering lever 38 with the right hand and the fuselage. Even when the direction is corrected, the left hand can be extended to the operation tool of the first operation tool group, and this can be operated, so that a quick response is possible.
　また、第１の操作具群の後方には、機体の走行変速を行う操作具（主変速レバー６２、副変速レバー６３）を配置する。これにより、オペレータが運転席９から立ち上がった状態でも、機体の前後進操作、或いは圃場内移動速度（中速、又は高速）に変速することができる。そして、機体の走行変速を行う操作具の後方には、操作頻度の低い第２の操作具群を配置する。ところで、係る第２の操作具群は、刈取り脱穀作業開始時、又は終了後に一度、操作すれば足り、刈取り脱穀作業中には殆んど操作することが稀な操作具（旋回モード設定ダイヤル６７、唐箕風量設定ダイヤル６８、選別ダイヤル６９、ＤＰＦスイッチ７０）であるから、オペレータが運転席９に座った状態で落ち着いて操作できれば事が足りる。 Also, behind the first operating tool group, operating tools (main transmission lever 62 and sub-transmission lever 63) for performing a traveling shift of the aircraft are arranged. As a result, even when the operator stands up from the driver's seat 9, it is possible to shift to the forward / reverse operation of the machine body or the moving speed in the field (medium speed or high speed). And the 2nd operation tool group with low operation frequency is arrange | positioned behind the operation tool which performs the traveling shift of a body. By the way, the second operating tool group needs to be operated once at the start of the mowing and threshing operation or after the end, and the operating tool rarely operated during the mowing and threshing work (the turning mode setting dial 67). Since the air volume setting dial 68, the selection dial 69, and the DPF switch 70), it is sufficient that the operator can operate calmly while sitting in the driver's seat 9.
　さらに、第２の操作具群を第１の操作具群に加えると、第１の操作具群の操作具数が増えて第１の操作具群の設置スペースを広くとらなければならず、後方に設ける機体の走行変速を行う操作具（主変速レバー６２、副変速レバー６３）の配置位置に支障を来す虞がある。しかし、第２の操作具群に分けて、第１の操作具群の操作具数を必要最小限に止めることによって、これを解消することができる。また、第１の操作具群の操作具数が少なく、両者を加えたもののように操作具が混在しないため、必要な操作具を誤りなく選定することができ、迅速な対応によって刈取り脱穀精度を向上させることができる。 Furthermore, when the second operating tool group is added to the first operating tool group, the number of operating tools in the first operating tool group increases, so that the installation space for the first operating tool group must be increased, and the rear There is a risk of hindering the position of the operation tools (main transmission lever 62, auxiliary transmission lever 63) for performing the traveling shift of the machine body provided in the vehicle. However, this can be solved by dividing the second operating tool group into the necessary minimum number of operating tools in the first operating tool group. In addition, since the number of operating tools in the first operating tool group is small and the operating tools are not mixed as in the case where both are added, the necessary operating tools can be selected without error, and the scouring and threshing accuracy can be improved by quick response. Can be improved.
　そして、本発明は、第１の操作具群の中の個々の操作具の配置についても考慮する。即ち、第１の操作具群の操作具の中にも自ずと操作頻度に高低差が生ずる。例えば、刈取り作業前後、或いは圃場内移動走行の前後には、刈取りクラッチと脱穀クラッチの断続操作を必要とする。また、刈取りクラッチと脱穀クラッチの断続操作を行うと、それに合わせてエンジン回転数を刈取り脱穀作業に必要な高回転に変更する、又は移動走行に適した回転数に変更する、或いは一時的に機体を停止する待機状態では、アイドリング状態に変更するといった操作が必要となり、これらの操作は、他の操作に比べて操作頻度が高い。 And this invention also considers arrangement | positioning of each operation tool in the 1st operation tool group. That is, the operating frequency of the operating tools in the first operating tool group naturally varies in height. For example, before and after the cutting operation or before and after the traveling in the field, an intermittent operation of the cutting clutch and the threshing clutch is required. In addition, when the intermittent operation of the mowing clutch and the threshing clutch is performed, the engine speed is changed to a high speed necessary for the mowing and threshing work, or the speed is changed to a speed suitable for traveling, or temporarily In the standby state in which the operation is stopped, operations such as changing to the idling state are required, and these operations are performed more frequently than other operations.
　従って、第１の操作具群の中でも操作頻度が高い刈取りクラッチと脱穀クラッチを断続する操作具（パワークラッチスイッチ４４）と、エンジン回転数を設定する操作具（エンジン回転自動ダイヤル４６）とを、第１の操作具群を設けるスイッチケース４２の最も右寄りに配置する。それ故、これらの操作具は最も運転席３１に近くなり、運転席３１から立ち上がったオペレータが左手で素早く操作することができる。また、これらの操作具の操作タイミングは略前後するから、一方の操作具を操作した後、他方の操作具への移行を極短時間で行うことができ、操作頻度が高くともオペレータの疲労を軽減して、作業能率を向上させることができる。 Therefore, an operation tool (power clutch switch 44) for connecting and disconnecting a reaping clutch and a threshing clutch, which are frequently operated in the first operation tool group, and an operation tool (engine rotation automatic dial 46) for setting the engine speed, The switch case 42 provided with the first operating tool group is arranged on the rightmost side. Therefore, these operating tools are closest to the driver's seat 31, and an operator who stands up from the driver's seat 31 can quickly operate with the left hand. In addition, since the operation timing of these operating tools is approximately before and after, after operating one operating tool, the transition to the other operating tool can be performed in a very short time, and even if the operating frequency is high, the operator is fatigued. It can be reduced and work efficiency can be improved.
　また、刈取り脱穀作業中に前処理部２や脱穀部３に詰まり等が発生した際には、刈取りクラッチと脱穀クラッチを断続する操作具（パワークラッチスイッチ４４）を操作して、いち早く刈取部Ｂと脱穀部Ｃを停止させることができ、それにより深刻な詰まりの発生を防止することができる。さらに、エンジン回転数を設定する操作具（エンジン回転自動ダイヤル４６）を液晶表示部１４に最も近い側に設けるから、液晶表示部１４に表示されるエンジン回転数を視野に入れながら適正なエンジン回転数に素早く設定することができると共に、同じく液晶表示部１４に表示されるエンジン負荷率に基づいてエンジン回転数を増減して、余裕を持ったエンジン負荷状態で刈取り脱穀作業を能率的に行うことができる。 In addition, when clogging or the like occurs in the preprocessing unit 2 or the threshing unit 3 during the mowing and threshing operation, the operating tool (power clutch switch 44) for intermittently connecting the mowing clutch and the threshing clutch is operated, and the mowing unit B is quickly activated. And the threshing portion C can be stopped, thereby preventing the occurrence of serious clogging. In addition, since an operating tool (engine rotation automatic dial 46) for setting the engine speed is provided on the side closest to the liquid crystal display unit 14, an appropriate engine speed is set while taking into account the engine speed displayed on the liquid crystal display unit 14. The number of engine revolutions can be increased or decreased based on the engine load factor similarly displayed on the liquid crystal display unit 14 and cutting and threshing can be efficiently performed in a sufficiently loaded engine state. Can do.
　また、刈取りクラッチと脱穀クラッチを断続する操作具（パワークラッチスイッチ４４）とエンジン回転数を設定する操作具（エンジン回転自動ダイヤル４６）を除く第１の操作具群の操作頻度は、細かく検討すれば相互の操作具間で差異があるが、その差はあまり大きくない。そこで、ここでは、操作具の機能に基づく関連性（纏まり）を第１に考慮すると共に、第２に周囲の設置環境、操作性等を総合的に判断して、操作具の配置を決定する。 Further, the operation frequency of the first operating tool group excluding the operating tool (power clutch switch 44) for connecting / disconnecting the mowing clutch and the threshing clutch and the operating tool (engine rotation automatic dial 46) for setting the engine speed should be examined in detail. For example, there is a difference between the operation tools, but the difference is not so large. Therefore, here, the relationship (group) based on the function of the operation tool is first considered, and secondly, the surrounding installation environment, operability, etc. are comprehensively determined to determine the arrangement of the operation tool. .
　即ち、第１の観点から機体の傾斜制御に関する水平手動レバー５４と水平ダイヤル５５と水平自動自動スイッチ５６、及び水平自動制御状態を表示するＬＥＤランプ５７は、同一領域に纏めて配置する。また、自動制御の入り切りのみを行うスイッチは、同一領域、又は近接して纏めて配置する。さらに、第２の観点から第１の操作具群は、機体の走行変速を行う操作具（主変速レバー６２、副変速レバー６３）の、特にグリップによつてオペレータから見た時、影になり易い。そこで、影になっても操作具の操作性を損なわない配置とする。 That is, from the first viewpoint, the horizontal manual lever 54, the horizontal dial 55, the horizontal automatic automatic switch 56, and the LED lamp 57 for displaying the horizontal automatic control state relating to the tilt control of the aircraft are arranged in the same area. In addition, switches that perform only automatic control on / off are arranged in the same region or close together. Further, from the second point of view, the first group of operating tools becomes a shadow when viewed from the operator by the grips of the operating tools (main transmission lever 62, sub-transmission lever 63) for performing the traveling shift of the airframe. easy. Therefore, the arrangement is such that the operability of the operation tool is not impaired even if it becomes a shadow.
　そして、具体的には、リフトシャットスイッチ４８とその状態を表示するＬＥＤランプ４９、及び方向自動スイッチ５０と扱深さ自動スイッチ５２、並びにそれらの状態を表示するＬＥＤランプ５１、５３は、自動制御の入り切りのみを行うスイッチであるから、纏めて配置する。また、これらの自動制御を入り切りするスイッチ４８、５０、５２は、指のタッチ操作で自動制御の入り切り操作を行うものであるから、操作空間をあまり必要としない。 Specifically, the lift shut switch 48 and the LED lamp 49 for displaying the state thereof, the direction automatic switch 50 and the handle depth automatic switch 52, and the LED lamps 51 and 53 for displaying the state thereof are automatically controlled. Since these are switches that only turn on and off, they are arranged together. Further, the switches 48, 50, and 52 for turning on / off the automatic control perform the on / off operation of the automatic control by a finger touch operation, so that an operation space is not so required.
　また、これらのスイッチ４８、５０、５２は、何れもタクタイルスイッチで構成し、スイッチケース４２の表面に設ける樹脂シート４３からのスイッチの突出量が少なく、走行変速を行う主変速レバー６２が最大前進側に操作され、オペレータから見てそのグリップ６２ａの影側になっても、上記少ない平面的な操作空間とグリップとスイッチの間隔を広くとることができる上下方向の操作空間とが相まって、操作に支障を来さないから、主変速レバー６２前方のスイッチケース４２の中央寄りに設ける。なお、主変速レバー６２が最大前進側に操作され、オペレータから見てそのグリップ６２ａの影側となる直下には、空きスペースＳを設け、この空きスペースＳを小物入れ等にすることもできる。 These switches 48, 50, 52 are all constituted by tactile switches, and the amount of protrusion of the switch from the resin sheet 43 provided on the surface of the switch case 42 is small, and the main transmission lever 62 that performs the traveling shift is maximally advanced. Even if it becomes the shadow side of the grip 62a when viewed from the operator side, the above small planar operation space and the operation space in the up and down direction in which the gap between the grip and the switch can be widened are combined. Since it does not hinder, it is provided near the center of the switch case 42 in front of the main transmission lever 62. In addition, the main transmission lever 62 is operated to the maximum forward side, and an empty space S is provided immediately below the shadow side of the grip 62a when viewed from the operator.
　さらに、水平手動レバー５４は、クロスレバースイッチで構成し、レバー５４のスイッチケース４２からの突出量は多く、また、レバー操作のための広い操作空間を必要とするから、機体３の走行変速を行う操作具（主変速レバー６２、副変速レバー６３）から最も離れたスイッチケース４２の左寄りの前部に設ける。また、水平自動自動スイッチ５６は、自動制御を入り切りするスイッチで操作空間をあまり必要としないから、水平手動レバー５４と同一領域に設けるものの、リフトシャットスイッチ４８と並ぶ、主変速レバー６２前方となる水平手動レバー５４の右側に設ける。さらに、水平自動自動スイッチ５６に付随する水平自動制御状態を表示するＬＥＤランプ５７も水平自動自動スイッチ５６に近接して設ける。残る水平ダイヤル５５は水平手動レバー５４の後方に設ける。 Further, the horizontal manual lever 54 is constituted by a cross lever switch, and the protrusion amount of the lever 54 from the switch case 42 is large, and a large operation space for lever operation is required. It is provided at the front left side of the switch case 42 that is farthest from the operating tools (the main transmission lever 62 and the auxiliary transmission lever 63) to be performed. Further, the horizontal automatic automatic switch 56 is a switch for turning on and off automatic control and does not require much operation space. Therefore, although it is provided in the same area as the horizontal manual lever 54, it is in front of the main transmission lever 62, which is aligned with the lift shut switch 48. Provided on the right side of the horizontal manual lever 54. Further, an LED lamp 57 for displaying a horizontal automatic control state associated with the horizontal automatic switch 56 is also provided in the vicinity of the horizontal automatic switch 56. The remaining horizontal dial 55 is provided behind the horizontal manual lever 54.
　そして、最後に残った刈り高さダイヤル６１は、スイッチケース４２の左寄りの後部に設ける。なお、水平ダイヤル５５と刈り高さダイヤル６１は、ダイヤルを掴んで回転操作するため広い操作空間を必要とし、また、多少スイッチケース４２から突出するから、走行変速を行う操作具の影側から離してこれらの操作性を確保する。また、こらのダイヤル５５、６１は、副変速レバー６３の前方側に設けることになるが、副変速レバー６３を最大に前方側に傾倒させた変速段は走行（高速）となるから、刈取り脱穀作業中に副変速レバー６３が、係る走行段に変速されることは少なく、これらのダイヤル５５、６１を副変速レバー６３の前方側に設けても大きな支障はない。 The last remaining cutting height dial 61 is provided at the rear left side of the switch case 42. Note that the horizontal dial 55 and the cutting height dial 61 require a wide operation space for gripping and rotating the dial, and slightly protrude from the switch case 42. To ensure these operability. These dials 55 and 61 are provided on the front side of the sub-shift lever 63. However, since the shift stage in which the sub-shift lever 63 is tilted to the front side at the maximum is traveling (high speed), cutting and threshing is performed. The auxiliary transmission lever 63 is rarely shifted to such a travel stage during work, and even if these dials 55 and 61 are provided on the front side of the auxiliary transmission lever 63, there is no major problem.
　なお、第１の操作具群の操作具の配置は前述した通りであるが、コンバイン１の仕様や型式によって第１の操作具群の操作具の種類や、操作具の数を変更する場合がある。即ち、図１７に示す例は、機体の傾斜制御を左右傾斜制御のみ行い、前後傾斜制御を行わないものであって、水平手動レバー５４の前後方向操作によって、機体の左右を同時に上げ又は下げ操作できるようにする。また、水平自動自動スイッチ５６は左右水平制御の入り切りのみを行うようにして、ＬＥＤランプ５７の数も減らす。さらに、水平ダイヤル５５はボリュームを回転させるものだけにし、スイッチを無くす。 The arrangement of the operating tools in the first operating tool group is as described above, but the type of operating tools in the first operating tool group and the number of operating tools may be changed depending on the specifications and model of the combine 1. is there. That is, in the example shown in FIG. 17, only the left / right tilt control is performed for the tilt control of the aircraft, and the forward / backward tilt control is not performed. It can be so. In addition, the horizontal automatic switch 56 only turns on / off the horizontal control to reduce the number of LED lamps 57. Furthermore, the horizontal dial 55 is only for rotating the volume, and there is no switch.
　また、図１８に示す例は、機体の傾斜制御に関する制御を無くし、水平手動レバー５４、水平ダイヤル５５、水平自動自動スイッチ５６、水平自動制御状態を表示するＬＥＤランプ５７を全て取り去ったものである。さらに、図１９に示す例は、汎用型コンバインにおける第１の操作具群の配置を示し、この場合、機体の傾斜制御は左右傾斜制御のみ行い、前後傾斜制御を行わない。また、水平手動レバー５４の前後方向操作によって、機体の左右を同時に上げ又は下げ操作できるようにする。 Further, in the example shown in FIG. 18, the control relating to the tilt control of the airframe is eliminated, and the horizontal manual lever 54, the horizontal dial 55, the automatic horizontal switch 56, and the LED lamp 57 for displaying the automatic horizontal control state are all removed. . Furthermore, the example shown in FIG. 19 shows the arrangement of the first operating tool group in the general-purpose combiner. In this case, the tilt control of the aircraft is performed only in the left / right tilt control, and the forward / backward tilt control is not performed. In addition, by operating the horizontal manual lever 54 in the front-rear direction, the left and right sides of the aircraft can be simultaneously raised or lowered.
　さらに、水平自動自動スイッチ５６は、左右水平制御、又は対地平衡制御に切替えできるようにする。なお、対地平衡制御は前処理部２を構成するヘッダ部の下部にソリセンサを設け、係るソリセンサによってヘッダ部の左右が地面（畝）に平行になるように左右傾斜制御する。また、水平ダイヤル５５に替えて、リール回転ダイヤル７３と自動制御の入り切り状態を表示するＬＥＤランプ７４を設ける。リール回転ダイヤル７３は、モーメンタリ型のスイッチとボリュームを作動させ、ダイヤル７３を押す度にスイッチがオンとなり、リール回転自動制御が入り・切りされる。また、ダイヤル７３によってボリュームを回転させると、回転角度に応じたリール回転数が設定される。 Furthermore, the horizontal automatic switch 56 can be switched to left / right horizontal control or ground balance control. The ground balance control is provided with a warp sensor at the lower part of the header part constituting the pre-processing unit 2, and the warp sensor controls the horizontal inclination so that the left and right sides of the header part are parallel to the ground. Further, in place of the horizontal dial 55, a reel rotation dial 73 and an LED lamp 74 for displaying an automatic control on / off state are provided. The reel rotation dial 73 operates a momentary type switch and volume, and the switch is turned on each time the dial 73 is pressed, and automatic reel rotation control is turned on / off. Further, when the volume is rotated by the dial 73, the reel rotation speed corresponding to the rotation angle is set.
　なお、リール回転自動制御は、ヘッダ部に設ける掻き込みリールの回転数を車速に同調するように自動制御するものであり、掻き込みリールの回転数はリール回転ダイヤル７３で調整することもできる。また、方向自動制御と扱ぎ深さ自動制御は行わないので、方向自動スイッチ５０と扱ぎ深さ自動スイッチ５２を無くす替りに、対地刈高自動スイッチ７５と自動制御の入り切り状態を表示するＬＥＤランプ７６を設ける。なお、対地刈高自動制御はソリセンサの検出値に基づいてヘッダ部を自動的に昇降し、材料の刈り高さを制御するものである。 The reel rotation automatic control is to automatically control the rotation speed of the scraping reel provided in the header portion so as to synchronize with the vehicle speed, and the rotation speed of the scraping reel can be adjusted by the reel rotation dial 73. In addition, since automatic direction control and automatic handle depth control are not performed, instead of eliminating automatic direction switch 50 and automatic handle depth switch 52, an LED for displaying on / off status of automatic cutting height switch 75 and automatic control is displayed. A lamp 76 is provided. The ground cutting height automatic control automatically raises and lowers the header portion based on the detection value of the warp sensor to control the cutting height of the material.

　液晶表示部１４は、作業画面である詳細表示画面ＡＡ、シンプル表示画面ＢＢ及びカメラ画像表示画面ＣＣを切換操作可能な状態で表示するにあたり、キースイッチＳＷがＯＮ操作されたとき、前回の作業時に最後に表示した作業画面を初期画面として表示させる。例えば、カメラ画像表示画面ＣＣを表示させた状態でキースイッチＳＷをＯＦＦ操作した場合、次回キースイッチＳＷがＯＮ操作されたとき、カメラ画像表示画面ＣＣが初期画面として表示される。なお、本実施形態では、カメラ画像拡大表示画面ＤＤを表示させた状態でキースイッチＳＷをＯＦＦ操作した場合、次回キースイッチＳＷがＯＮ操作されたとき、カメラ画像表示画面ＣＣが初期画面として表示されるが、カメラ画像拡大表示画面ＤＤが初期画面として表示されるようにしてもよい。 The liquid crystal display unit 14 displays the detail display screen AA, the simple display screen BB, and the camera image display screen CC, which are work screens, in a switchable state, when the key switch SW is turned ON, and during the previous work. The last displayed work screen is displayed as the initial screen. For example, when the key switch SW is turned off while the camera image display screen CC is displayed, the next time the key switch SW is turned on, the camera image display screen CC is displayed as an initial screen. In the present embodiment, when the key switch SW is turned OFF while the camera image enlarged display screen DD is displayed, the next time the key switch SW is turned ON, the camera image display screen CC is displayed as the initial screen. However, the camera image enlargement display screen DD may be displayed as the initial screen.
　また、液晶表示部１４に設定画面ＥＥが表示された状態でキースイッチＳＷがＯＦＦ操作された場合は、次回キースイッチＳＷがＯＮ操作されたとき、設定画面ＥＥではなく、前回の作業時に最後に表示した作業画面を初期画面として表示させる。例えば、詳細表示画面ＡＡから設定画面ＥＥに移行し、設定画面ＥＥの表示状態でキースイッチＳＷがＯＦＦ操作された場合は、次回キースイッチＳＷがＯＮ操作されたとき、詳細表示画面ＡＡが初期画面として表示される。 When the key switch SW is turned off while the setting screen EE is displayed on the liquid crystal display unit 14, the next time the key switch SW is turned on, not the setting screen EE but the last time in the previous work. The displayed work screen is displayed as an initial screen. For example, when the detailed display screen AA is shifted to the setting screen EE and the key switch SW is turned OFF in the display state of the setting screen EE, the next time the key switch SW is turned ON, the detail display screen AA is the initial screen. Is displayed.
　図２７及び図２８に示すように、液晶表示部１４は、機体の異常状態を表示する異常報知を行う。報知する異常項目には、異常の発生に応じて警報が行われる警報項目と、異常の発生に応じてエンジンが停止されるエンジン停止項目とが含まれている。例えば、警報項目としては、エンジ過負荷警報、エンジオイル不足警報、バッテリ電圧異常警報、選別過負荷警報、１番ラセン、２番ラセン過負荷警報、エアクリーナ異常警報、ＤＰＦ警報、エンジ冷却水温異常警報、ノッタ紐切れ警報、グレンタク満杯警報などがあり、エンジン停止項目としては、前処理部詰まり、１番ラセン、２番ラセン詰まり、排ワラ詰まり、結束機詰まり、グレンタクオーバーフロー、エンジ停止スイッチ操作などがある。 As shown in FIGS. 27 and 28, the liquid crystal display unit 14 performs an abnormality notification for displaying an abnormal state of the aircraft. The abnormal items to be notified include an alarm item for performing an alarm in response to the occurrence of an abnormality and an engine stop item for stopping the engine in response to the occurrence of an abnormality. For example, the alarm items include engine overload alarm, engine oil shortage alarm, battery voltage abnormality alarm, sorting overload alarm, first spiral, second spiral overload alarm, air cleaner abnormality alarm, DPF alarm, engine cooling water temperature abnormality alarm , Nota cord breakage alarm, Glentak full alarm, etc. Engine stop items include pre-processing blockage, 1st helix, 2nd helix clogging, waste straw clogging, bundling machine clogging, Glentack overflow, engine stop switch operation, etc. There is.
　図２７に示すように、警報項目に係る異常報知は、表示中画面の上に重なるポップアップウインドウにより表示される。例えば、図２７に示す警報項目に係る異常報知は、バッテリ電圧異常警報であり、異常内容を示す「バッテリ充電不足です。」というメッセージと、異常に対する対処方法を示す「オルタネータのベルトを点検してください。」というメッセージが含まれている。ちなみに、警報項目に係る異常報知画面の背景は、「黄色」などの注意を喚起し得る色を選択することが好ましい。 As shown in FIG. 27, the abnormality notification related to the alarm item is displayed by a pop-up window overlapping the currently displayed screen. For example, the abnormality notification related to the alarm item shown in FIG. 27 is a battery voltage abnormality alarm, a message “Battery charge is insufficient” indicating the abnormality content, and a message “Inspecting the alternator belt” Please include "message. Incidentally, it is preferable to select a color that can call attention such as “yellow” as the background of the abnormality notification screen related to the alarm item.
　図２０～図２３、図２７に示すように、警報項目に係る異常報知は、人為操作に応じた拡大表示と縮小表示との表示切換えが可能となっている。つまり、異常警報の表示当初は、図２７に示す拡大表示で異常状態に対する注意を喚起するが、警報項目に係る異常状態は、発生しても作業の継続が可能であるため、そのまま作業を継続する場合は、異常報知を縮小表示とすることで、作業画面の表示を優先させることができる。本実施形態では、図２７に示す異常表示領域をタップ操作すると、図２０～図２３に示すように、異常表示が画面下部に縮小表示される。縮小表示では、異常に対する対処方法は表示されず、異常内容のみが表示される。また、縮小表示された異常表示領域をタップ操作すると、図２７に示す拡大された異常表示に切り換わる。ちなみに、異常表示を縮小表示すると、注意喚起効果が低下するので、縮小された異常表示の背景は、「黄色」よりも注意喚起効果が高い「赤色」などを選択することが好ましい。 As shown in FIG. 20 to FIG. 23 and FIG. 27, the abnormality notification related to the alarm item can be switched between enlarged display and reduced display according to human operation. That is, at the beginning of the display of the abnormal alarm, attention is paid to the abnormal state by the enlarged display shown in FIG. 27, but the work can be continued even if the abnormal state related to the alarm item occurs, so the work is continued as it is. In this case, the display of the work screen can be prioritized by reducing the abnormality notification to a reduced display. In the present embodiment, when the abnormality display area shown in FIG. 27 is tapped, the abnormality display is reduced and displayed at the bottom of the screen as shown in FIGS. In the reduced display, the countermeasure for the abnormality is not displayed, and only the abnormality content is displayed. Further, when a tampering operation is performed on the reduced abnormality display area, the display is switched to the enlarged abnormality display shown in FIG. Incidentally, when the abnormal display is reduced, the alerting effect is reduced. Therefore, it is preferable to select “red” or the like that has a higher alerting effect than “yellow” as the background of the reduced abnormal display.
　図２８に示すように、エンジン停止項目に係る異常表示は、表示中画面を切換えて全画面で表示される。例えば、図２８に示すエンジン停止項目に係る異常報知は、前処理部詰まりであり、異常内容を示す「前処理部詰まり」というメッセージと、異常に対する対処方法を示す「前処理部が詰まりました　点検してください」というメッセージと、「問題を解決しなければこの画面は消えません」というメッセージが含まれている。ちなみに、エンジン停止項目に係る異常報知画面の背景は、「黄色」（警報項目に係る拡大異常表示の背景色）よりも注意喚起効果が高い「赤色」を選択することが好ましい。 As shown in FIG. 28, the abnormality display related to the engine stop item is displayed on the full screen by switching the display screen. For example, the abnormality notification related to the engine stop item shown in FIG. 28 is a pre-processing unit clogging, a message “clogging pre-processing unit” indicating the content of the abnormality, and “pre-processing unit clogged” indicating a countermeasure for the abnormality. Please check "message and" This screen will not disappear unless the problem is solved ". Incidentally, it is preferable to select “red”, which has a higher alerting effect than “yellow” (background color of the enlarged abnormality display related to the alarm item) as the background of the abnormality notification screen related to the engine stop item.
　エンジン停止項目に係る異常表示は、人為操作に応じた表示切換えが不可能となっており、異常原因が解消されるまで表示が継続される。一方、警報項目に係る異常表示は、人為操作に応じた縮小表示への切換えが可能であり、この状態で作業を継続することが可能であるが、警報項目に係る異常表示（拡大表示及び縮小表示を含む）も、異常原因が解消されるまで表示が継続されるので、異常に対する確実な対応を促すことができる。 異常 The display of abnormality related to the engine stop item cannot be switched according to human operation, and the display is continued until the cause of the abnormality is resolved. On the other hand, the abnormal display related to the alarm item can be switched to the reduced display according to the manual operation, and the work can be continued in this state. However, the abnormal display related to the alarm item (enlarged display and reduced display) Since the display continues until the cause of the abnormality is resolved, a reliable response to the abnormality can be promoted.
　複数の異常項目が発生している状況では、これらの異常報知を同時に実行することが不可能であるため、予め優先順位を定めている。例えば、警報項目よりもエンジン停止項目の異常を優先するとともに、エンジン停止項目に含まれる複数の異常種別について優先順位を定め、また、警報項目に含まれる複数の異常種別についても優先順位を定めている。そして、複数の異常項目が発生した場合は、予め定めされた優先順位に従い、優先順位の高い異常項目から異常表示を行う。 In a situation where a plurality of abnormal items have occurred, it is impossible to simultaneously execute these abnormal notifications, and therefore priorities are set in advance. For example, priority is given to the abnormality of the engine stop item over the alarm item, a priority order is set for a plurality of abnormality types included in the engine stop item, and a priority order is set for a plurality of abnormality types included in the alarm item. Yes. Then, when a plurality of abnormal items occur, the abnormal display is performed from the abnormal item having the higher priority according to the predetermined priority.
　図２９に示すように、液晶表示部１４では、主にディーラのサービスマンが利用するディーラメニュー画面ＦＦを表示させることができる。ディーラメニュー画面ＦＦへの移行は、例えば、設定画面ＥＥにおいて、予め決められた１又は複数のタッチ操作ボタン２５ａ～２５ｅを長押し操作することにより行われる。 As shown in FIG. 29, the liquid crystal display unit 14 can display a dealer menu screen FF mainly used by a dealer service person. The transition to the dealer menu screen FF is performed, for example, by long-pressing one or more predetermined touch operation buttons 25a to 25e on the setting screen EE.
　図３０に示すように、ディーラメニュー画面ＦＦでは、タッチ操作ボタン２５ａ、２５ｂ、２５ｅのボタン名称としてそれぞれ「入力チェック」、「履歴」、「戻る」が付加されている。タッチ操作ボタン２５ａをタップ操作すると、図示しない入力チェック画面が表示され、タッチ操作ボタン２５ｂをタップ操作すると、図１９に示すエラー履歴画面ＧＧが表示され、タッチ操作ボタン２５ｅをタップ操作すると、設定画面ＥＥに戻る。ちなみに、入力チェック画面は、センサなどの信号入力をチェックするための画面であり、例えば、チェックしたい部品の操作に応じて、表示制御部２４に正常な信号が入力された場合、それをブザー音で報知する。本実施形態では、入力チェック画面を特殊モードとして扱う。特殊モードとは、一旦移行すると、前の画面に戻ることが規制される制御状態を意味し、エンジンが停止するまでその画面表示が維持される。 As shown in FIG. 30, on the dealer menu screen FF, “input check”, “history”, and “return” are added as button names of the touch operation buttons 25a, 25b, and 25e, respectively. When the touch operation button 25a is tapped, an input check screen (not shown) is displayed. When the touch operation button 25b is tapped, an error history screen GG shown in FIG. 19 is displayed. When the touch operation button 25e is tapped, a setting screen is displayed. Return to EE. Incidentally, the input check screen is a screen for checking the signal input of the sensor or the like. For example, when a normal signal is input to the display control unit 24 according to the operation of the component to be checked, it is buzzer sounded. To inform. In this embodiment, the input check screen is handled as a special mode. The special mode means a control state in which returning to the previous screen is restricted once a transition is made, and the screen display is maintained until the engine stops.
　図３１に示すように、エラー履歴画面ＧＧでは、エラー履歴番号（例えば、エラー履歴０１）、エラー発生時間（例えば、アワメータ８８８８．８）及びエラー内容（例えば、前処理詰まり（エンジン停止））で特定される複数のエラー履歴が、時系列で上下方向に並べて表示される。エラー履歴画面ＧＧに表示されるエラー履歴には、電装部品系エラー履歴として記憶された電装部品の異常に関するエラー情報と、機体状態系エラー履歴として記憶された機体状態の異常に関するエラー情報と、が含まれており、電装部品系エラー履歴及び機体状態系エラー履歴が時系列で一元的に表示される。このようなエラー履歴表示によれば、電装部品系エラーの発生原因をそれ以前の機体状態系エラー履歴に基づいて究明することが可能になる。例えば、前処理詰まりが２回発生した後に、前処理リフトボテンショエラーが発生している場合、前処理詰まりに起因する前処理リフトポテンショの異常と考えられるので、単に前処理リフトポテンショを交換するだけでなく、その周辺の破損の有無の確認が必要であることを理解できる。 As shown in FIG. 31, on the error history screen GG, the error history number (for example, error history 01), error occurrence time (for example, hour meter 8888.8), and error content (for example, pre-processing clogging (engine stop)) are displayed. A plurality of specified error histories are displayed side by side in the vertical direction in time series. The error history displayed on the error history screen GG includes error information related to the abnormality of the electrical component stored as the electrical component system error history, and error information related to the abnormality of the aircraft status stored as the aircraft status system error history. It is included, and the electrical component system error history and the fuselage status error history are displayed in a time series. According to such an error history display, it is possible to investigate the cause of the occurrence of an electrical component system error based on the previous body state system error history. For example, if a pretreatment lift potentiometer error occurs after two pretreatment clogs have occurred, it is considered that the pretreatment lift potentiometer is abnormal due to the pretreatment clogging, so the pretreatment lift potentiometer is simply replaced. In addition, it can be understood that it is necessary to confirm whether there is damage in the surrounding area.
　図３１には、機体状態系エラー履歴として表示される機体状態系エラーの項目として、エラーの発生に応じてエンジンが停止される前述のエンジン停止エラー項目のつり、前処理詰まりを例示しているが、その他のエンジン停止エラー項目が含まれることは言うまでもない。また、機体状態系エラー履歴として表示される機体状態系エラーの項目として、エラーの発生に応じて警報が行われる前述の警報エラー項目を含むようにしてもよい。このようにすると、例えば、伝動ベルトが破損して交換する場合に、エラー履歴として選別やラセンの過負荷警報履歴が残っていれば、オペレータの機械の使用方法に原因があると推定することが可能になる。 FIG. 31 exemplifies the above-mentioned engine stop error item in which the engine is stopped in response to the occurrence of an error, and preprocessing clogging, as an item of the airframe state error displayed as the airframe state error history. However, it goes without saying that other engine stop error items are included. Further, the above-described alarm error item in which an alarm is issued in response to the occurrence of an error may be included as an item of the airframe state error displayed as the airframe state error history. In this way, for example, when the transmission belt is damaged and replaced, if there is a selection or spiral overload alarm history as an error history, it may be assumed that there is a cause in how the operator uses the machine. It becomes possible.
　エラー履歴画面ＧＧでは、エラーの種別に応じてエラー履歴の表示色を相違させることが好ましい。例えば、電装部品系エラー履歴を「黄色」、機体状態系エラー履歴を「赤色」で表示させる。このようにすると、表示色に基づいてエラーの種別を識別できるので、エラーの原因究明が容易になる。 In the error history screen GG, it is preferable to change the display color of the error history according to the type of error. For example, the electrical component system error history is displayed in “yellow”, and the machine status error history is displayed in “red”. In this way, since the type of error can be identified based on the display color, it becomes easy to investigate the cause of the error.
　つぎに、上記のような液晶表示部１４の画面切換操作及び表示動作を実現する表示制御部２４の制御手順について、図３２～図３５を参照して説明する。 Next, the control procedure of the display control unit 24 for realizing the screen switching operation and display operation of the liquid crystal display unit 14 as described above will be described with reference to FIGS.
　表示制御部２４は、ハードウエアとソフトウエアとの協働により実現される機能的な構成として、初期表示制御手段、拡大表示手段、異常報知手段及びエラー履歴表示手段を備えており、以下、初期表示制御手段を実現する初期表示制御と、拡大表示手段を実現する画面表示切換制御と、異常報知手段を実現する異常報知制御と、エラー履歴表示手段を実現するエラー履歴表示制御の具体的な制御手順を説明する。 The display control unit 24 includes an initial display control unit, an enlarged display unit, an abnormality notification unit, and an error history display unit as a functional configuration realized by the cooperation of hardware and software. Specific control of initial display control for realizing display control means, screen display switching control for realizing enlarged display means, abnormality notification control for realizing abnormality notification means, and error history display control for realizing error history display means Explain the procedure.
　図３２に示すように、初期表示制御では、まず、エンジンが停止状態であるか否かを判断するとともに（Ｓ１１）、キースイッチＳＷのＯＮ操作を判断し（Ｓ１２）、ここで両判断の結果がいずれもＹＥＳである場合は、記憶画面の有無を判断する（Ｓ１３）。この判断結果が無しである場合は、作業画面である詳細表示画面Ａ、シンプル表示画面Ｂ及びカメラ画像表示画面Ｃのうち、予め定められたデフォルト作業画面（例えば、詳細表示画面）を液晶表示部１４に表示させる一方（Ｓ１４）、記憶画面が有ると判断した場合は、記憶している作業画面を液晶表示部１４に表示させる（Ｓ１５）。続いて、画面表示切換制御（Ｓ１６）、異常報知制御（Ｓ１７）、エラー履歴表示制御（Ｓ１８）などのサブルーチンを実行した後、現在の表示画面が作業画面であるかそれ以外の画面であるかを判断する（Ｓ１９）。ここで作業画面であると判断した場合は、現在表示している作業画面の種別を記憶（記憶画面の書換）する一方（Ｓ２０）、作業画面以外であると判断した場合は、そのまま上位ルーチンへ復帰する。これにより、キースイッチＳＷがＯＮ操作されたとき、前回の作業時に最後に表示した作業画面を初期画面として表示させることが可能になる。 As shown in FIG. 32, in the initial display control, first, it is determined whether or not the engine is stopped (S11), and the ON operation of the key switch SW is determined (S12). If both are YES, the presence / absence of a storage screen is determined (S13). If the determination result is none, a predetermined default work screen (for example, a detailed display screen) among the detailed display screen A, the simple display screen B, and the camera image display screen C, which are work screens, is displayed on the liquid crystal display unit. 14 (S14), if it is determined that there is a storage screen, the stored work screen is displayed on the liquid crystal display unit 14 (S15). Subsequently, after executing subroutines such as screen display switching control (S16), abnormality notification control (S17), and error history display control (S18), whether the current display screen is a work screen or any other screen. Is determined (S19). If it is determined that the screen is a work screen, the type of the currently displayed work screen is stored (rewrite of the storage screen) (S20). Return. As a result, when the key switch SW is turned on, it is possible to display the work screen displayed last during the previous work as the initial screen.
　図３３に示すように、画面表示切換制御では、物理的操作ボタン２６ａ～２６ｅの操作及び液晶表示部１４のタッチ操作（タップ操作及びフリック操作）を判断する（Ｓ３１、Ｓ３３、Ｓ４０）。物理的操作ボタン２６ａ～２６ｅが操作されたと判断した場合は、操作された物理的操作ボタン２６ａ～２６ｅに対応する画面を液晶表示部１４に表示させる（Ｓ３２）。また、液晶表示部１４がタップ操作されたと判断した場合は、タップ操作位置がタッチ操作ボタン２５ａ～２５ｅであるか否か（Ｓ３４）、拡大操作有効領域であるか否か（Ｓ３５）、拡大戻し操作有効領域（Ｓ３６）であるか否かを判断する。ここで、タップ操作位置がタッチ操作ボタン２５ａ～２５ｅであると判断した場合は、タップ操作されたタッチ操作ボタン２５ａ～２５ｅに対応する画面を液晶表示部１４に表示させ（Ｓ３７）、タップ操作位置が拡大操作有効領域であると判断した場合は、タップ操作された拡大操作有効領域に対応する画面を液晶表示部１４に表示させ（Ｓ３８）、タップ操作位置が拡大戻し操作有効領域であると判断した場合は、タップ操作された拡大戻し操作有効領域に対応する画面を液晶表示部１４に表示させる（Ｓ３９）。また、液晶表示部１４がフリック操作されたと判断した場合は、フリック操作位置がフリック操作有効領域であるか否かを判断し（Ｓ４１）、この判断結果がＹＥＳの場合は、フリック操作されたフリック操作有効領域及びフリック操作方向に対応する画面を液晶表示部１４に表示させる（Ｓ４２）。 33, in the screen display switching control, the operation of the physical operation buttons 26a to 26e and the touch operation (tap operation and flick operation) of the liquid crystal display unit 14 are determined (S31, S33, S40). If it is determined that the physical operation buttons 26a to 26e have been operated, screens corresponding to the operated physical operation buttons 26a to 26e are displayed on the liquid crystal display unit 14 (S32). If it is determined that the liquid crystal display unit 14 has been tapped, whether or not the tap operation position is the touch operation buttons 25a to 25e (S34), whether or not the enlargement operation is effective (S35), and enlargement return. It is determined whether or not the operation effective area (S36). If it is determined that the tap operation positions are the touch operation buttons 25a to 25e, screens corresponding to the touch operation buttons 25a to 25e that have been tapped are displayed on the liquid crystal display unit 14 (S37). Is determined to be the enlargement operation effective area, a screen corresponding to the enlarged operation effective area that has been tapped is displayed on the liquid crystal display unit 14 (S38), and the tap operation position is determined to be the enlargement return operation effective area. If so, a screen corresponding to the enlargement / return operation effective area that has been tapped is displayed on the liquid crystal display 14 (S39). If it is determined that the liquid crystal display unit 14 has been flicked, it is determined whether or not the flick operation position is a flick operation effective area (S41). If the result of this determination is YES, the flicked flick has been determined. A screen corresponding to the operation effective area and the flick operation direction is displayed on the liquid crystal display unit 14 (S42).
　図３４に示すように、異常報知制御では、まず、異常状態が発生したか否かを判断し（Ｓ５１）、この判断結果がＮＯである場合は、異常表示をクリアするとともに（Ｓ５２）、異常表示の拡大・縮小を切り換えるためのフラグＦに初期値である「０」（拡大表示）をセットする（Ｓ５３）。一方、異常状態が発生していると判断した場合は、優先順位処理を実行する（Ｓ５４）。この優先順位処理は、複数の異常状態が発生している状況において、予め定められた優先順位に従い、優先的に異常表示を行う異常項目を抽出する処理である。つぎに、抽出した異常項目が「エンジン停止項目」、「警報項目」のいずれに属するかを判断し（Ｓ５５）、この判断結果が「エンジン停止項目」である場合は、当該異常項目に関する異常表示を液晶表示部１４に全画面表示する（Ｓ５６）。一方、「警報項目」に係る異常項目であると判断した場合は、フラグＦを参照し（Ｓ５７）、ここでフラグＦが「０」であると判断した場合は、当該異常項目に係る異常表示を液晶表示部１４にポップアップウインドウとして拡大表示させる（Ｓ５８）。その後、拡大表示領域のタップ操作を判断するとともに（Ｓ５９）、該判断結果がＹＥＳの場合は、フラグＦに「１」をセットする（Ｓ６０）。また、ステップＳ５７の判断結果が「１」である場合は、当該異常項目に係る異常表示を液晶表示部１４に縮小表示させる（Ｓ６１）。その後、縮小表示領域のタップ操作を判断するとともに（Ｓ６２）、該判断結果がＹＥＳの場合は、フラグＦに「０」をセットする（Ｓ６３）。 As shown in FIG. 34, in the abnormality notification control, first, it is determined whether or not an abnormal state has occurred (S51). If the determination result is NO, the abnormality display is cleared (S52), An initial value “0” (enlarged display) is set in a flag F for switching between enlargement / reduction of display (S53). On the other hand, if it is determined that an abnormal condition has occurred, priority order processing is executed (S54). This priority order process is a process for extracting an abnormal item to be preferentially displayed in accordance with a predetermined priority order in a situation where a plurality of abnormal states have occurred. Next, it is determined whether the extracted abnormal item belongs to “engine stop item” or “alarm item” (S55). If this determination result is “engine stop item”, an abnormality display related to the abnormal item is displayed. Is displayed on the full screen on the liquid crystal display unit 14 (S56). On the other hand, if it is determined that the item is an abnormal item related to “alarm item”, the flag F is referred to (S57). If it is determined that the flag F is “0”, an abnormal display related to the abnormal item is displayed. Is enlarged and displayed as a pop-up window on the liquid crystal display unit 14 (S58). Thereafter, the tap operation of the enlarged display area is determined (S59), and if the determination result is YES, "1" is set to the flag F (S60). If the determination result of step S57 is “1”, the abnormal display related to the abnormal item is reduced and displayed on the liquid crystal display unit 14 (S61). Thereafter, the tap operation of the reduced display area is determined (S62), and if the determination result is YES, "0" is set to the flag F (S63).
　図３５に示すように、エラー履歴表示制御では、まず、サブルーチンである電装部品系エラー履歴記憶処理（Ｓ７１）と機体状態系エラー履歴記憶処理（Ｓ７２）とを実行する。電装部品系エラー履歴記憶処理は、電装部品のエラーが発生した場合に、そのエラー種別を発生時間情報（アワメータ値）とともにエラー履歴データベースに記憶する処理であり、機体状態系エラー履歴記憶処理は、機体状態のエラーが発生した場合に、そのエラー種別を発生時間情報とともにエラー履歴データベースに記憶する処理である。つぎに、エラー履歴表示画面の表示操作を判断し（Ｓ７３）、該判断結果がＹＥＳである場合は、エラー履歴データベースに記憶された電装部品系エラー履歴及び機体状態系エラー履歴を液晶表示部１４に時系列で一元表示させる（Ｓ７４）。このとき、電装部品系エラー履歴と機体状態系エラー履歴は異なる色で表示される。 As shown in FIG. 35, in the error history display control, first, an electrical component system error history storage process (S71) and a body state system error history storage process (S72), which are subroutines, are executed. The electrical component system error history storage process is a process of storing the error type in the error history database together with the occurrence time information (hourmeter value) when an electrical component error occurs. This is a process of storing the error type in the error history database together with the occurrence time information when an error in the machine status occurs. Next, the display operation of the error history display screen is determined (S73). When the determination result is YES, the liquid crystal display unit 14 displays the electrical component system system error history and the body state system error history stored in the error history database. Are displayed in a time series (S74). At this time, the electrical component system error history and the machine state system error history are displayed in different colors.
　叙述の如く構成された第２実施形態によれば、表示制御部２４は、作業時に必要な情報を表示する複数種類の作業画面ＡＡ～ＣＣを切換操作可能な状態で液晶表示部１４に表示するにあたり、キースイッチＳＷがＯＮ操作されたとき、前回の作業時に最後に表示した作業画面ＡＡ～ＣＣを液晶表示部１４に表示させるので、キースイッチＳＷのＯＮ操作後、いちいち好みの作業画面ＡＡ～ＣＣに切り換える手間が不要となる。 According to the second embodiment configured as described, the display control unit 24 displays on the liquid crystal display unit 14 a plurality of types of work screens AA to CC for displaying information necessary at the time of operation in a switchable state. In this case, when the key switch SW is turned on, the work screens AA to CC that were last displayed during the previous work are displayed on the liquid crystal display unit 14. Therefore, after the key switch SW is turned on, the preferred work screens AA to CC are displayed. There is no need to switch to CC.
　また、複数種類の作業画面ＡＡ～ＣＣには、シンプル表示画面ＢＢ（第１作業画面）と、詳細表示画面ＡＡ（第２作業画面）と、カメラ画像表示画面ＣＣ（第３作業画面）と、が含まれ、シンプル表示画面ＢＢは、重要度が高い基本情報を表示し、詳細表示画面ＡＡは、基本情報と、該基本情報よりも重要度が低い附属情報とを表示し、カメラ画像表示画面ＣＣは、基本情報と、機体に設置されたカメラの画像とを表示するので、いずれの作業画面ＡＡ～ＣＣを選択しても、重要度が高い基本情報の表示を維持し、基本情報の欠如によって作業に支障をきたすことを防止できる。 The plurality of types of work screens AA to CC include a simple display screen BB (first work screen), a detail display screen AA (second work screen), a camera image display screen CC (third work screen), The simple display screen BB displays basic information with high importance, the detailed display screen AA displays basic information and auxiliary information with lower importance than the basic information, and a camera image display screen Since CC displays basic information and images of the camera installed on the aircraft, no matter which work screen AA to CC is selected, the display of basic information with high importance is maintained and the lack of basic information Can prevent work from being hindered.
　また、本実施形態の表示制御部２４は、各作業画面ＡＡ～ＣＣから設定画面ＥＥへの移行、及び、設定画面ＥＥから各作業画面ＡＡ～ＣＣへの移行を許容し、液晶表示部１４に設定画面ＥＥが表示された状態でキースイッチＳＷがＯＦＦ操作された場合、次回キースイッチＳＷがＯＮ操作されたとき、設定画面ＥＥではなく、前回の作業時に最後に表示した作業画面ＡＡ～ＣＣを液晶表示部１４に表示させるので、キースイッチＳＷのＯＮ操作後、いちいち設定画面ＥＥから好みの作業画面ＡＡ～ＣＣに切り換える手間が不要となる。 In addition, the display control unit 24 of the present embodiment allows the transition from the work screens AA to CC to the setting screen EE and the transition from the setting screen EE to the work screens AA to CC. When the key switch SW is turned off while the setting screen EE is displayed, when the key switch SW is turned on next time, not the setting screen EE but the work screens AA to CC displayed last in the previous work.
