（実施の形態１）
　本発明の本実施の形態による作業管理システム１０００を、図面を参照して説明する。本実施の形態において、図１に示すように、作業管理システム１０００は、作業管理装置１００と、作業装置２００と、端末３００とを備える。作業管理装置１００は、ネットワーク２０、例えばインターネットを介して、作業装置２００と、端末３００と通信可能に接続されている。 (Embodiment 1)
A work management system 1000 according to this embodiment of the present invention will be described with reference to the drawings. In this embodiment, a work management system 1000 includes a work management device 100, a work device 200, and a terminal 300, as shown in FIG. The work management device 100 is communicably connected to the work device 200 and the terminal 300 via the network 20, for example, the Internet.
　作業装置２００は、圃場内を移動しながら作業を行うように構成されている。作業装置２００、例えばトラクターには、図２に示すように、作業機械２１０、例えばロータリー、バーチカルハロー、ブロードキャスタなどが取り付けられている。作業装置２００は、作業機械２１０を牽引して圃場内を移動することで、農作業を行う。行われる農作業は、作業機械２１０の種類または機種により、特定することができる。 The work device 200 is configured to perform work while moving within the field. A working device 200, such as a tractor, is attached with a working machine 210, such as a rotary, a vertical harrow, a broadcaster, etc., as shown in FIG. The work device 200 performs farm work by pulling the work machine 210 to move in a field. Agricultural work to be performed can be specified by the type or model of the work machine 210 .
　作業機械２１０には、発信機２１５が設けられている。発信機２１５は、所定の間隔で発信機２１５の各々を区別するために設定された識別情報を送信する。発信機２１５は、例えばビーコンである。識別情報は、作業装置２００に設けられたデータ送信装置２２０を介して、図１に示す作業管理装置１００に送信される。 The work machine 210 is provided with a transmitter 215 . Transmitters 215 transmit identification information set to distinguish each transmitter 215 at predetermined intervals. Transmitter 215 is, for example, a beacon. The identification information is transmitted to the work management device 100 shown in FIG. 1 via the data transmission device 220 provided in the work device 200.
　作業管理装置１００は、発信機２１５からの識別情報に基づき、作業装置２００により行われた作業に関する作業情報、例えば作業期間、作業種別、作業領域などを特定する。作業種別は、圃場で行われた作業の種類、例えば耕起、整地、施肥、植付などを表す。作業領域は、作業が行われた領域を表し、例えば圃場内で作業が行われた領域や、作業が行われた圃場全体の領域を表す。 Based on the identification information from the transmitter 215, the work management device 100 identifies work information related to the work performed by the work device 200, such as work period, work type, and work area. The work type indicates the type of work performed in the field, such as plowing, leveling, fertilizing, and planting. The work area represents an area in which work has been performed, for example, an area in which work has been performed in a field or an entire field in which work has been performed.
　端末３００は、作業管理装置１００で特定された作業情報を表示する。これにより、ユーザは、圃場で行われた作業を確認して、栽培管理の分析を効率良く行うことができる。 The terminal 300 displays the work information specified by the work management device 100. As a result, the user can check the work performed in the field and efficiently analyze the cultivation management.
　ここで、識別情報は、データ送信装置２２０により正常に受信されない場合がある。例えば、大気環境により、図２に示す発信機２１５の電波が減衰して、データ送信装置２２０が識別情報を受信できない場合がある。また、作業装置２００は、牽引している作業機械２１０と異なる他の作業機械２１０に接近する場合がある。この場合、データ送信装置２２０は、他の作業機械２１０に設けられた発信機２１５が送信する識別情報を受信する。このように、データ送信装置２２０は、識別情報を受信できない場合や、他の発信機２１５の識別情報を受信する場合がある。 Here, the identification information may not be received normally by the data transmission device 220. For example, the atmospheric environment may attenuate the radio wave from the transmitter 215 shown in FIG. 2, preventing the data transmission device 220 from receiving the identification information. Also, work implement 200 may approach another work machine 210 that is different from the work machine 210 being towed. In this case, data transmission device 220 receives identification information transmitted by transmitter 215 provided in other work machine 210 . In this way, the data transmission device 220 may not be able to receive identification information, or may receive identification information from other transmitters 215 .
　このため、作業管理装置１００は、識別情報を補正することで、作業装置２００により行われた作業の作業期間、作業種別、作業領域などを特定する。これにより、作業管理システム１０００は、正確性の高い作業情報をユーザに提供することができる。 Therefore, the work management device 100 corrects the identification information to identify the work period, work type, work area, etc. of the work performed by the work device 200 . Thereby, the work management system 1000 can provide highly accurate work information to the user.
　データ送信装置２２０の構成を説明する。データ送信装置２２０は、図３に示すように、入出力装置２２１と、演算装置２２２と、通信装置２２３と、記憶装置２２４と、測位装置２２５と、受信機２２６とを備える。データ送信装置２２０は、例えば、タブレット、携帯電話などの携帯端末、コンピュータを含む。入出力装置２２１には、演算装置２２２が処理を実行するための情報が入力される。また、入出力装置２２１は、演算装置２２２が処理を実行した結果を出力する。入出力装置２２１は、様々な入力装置と出力装置とを含み、例えば、キーボード、マウス、マイク、ディスプレイ、スピーカー、タッチパネルなどを含む。 The configuration of the data transmission device 220 will be explained. The data transmission device 220 includes an input/output device 221, an arithmetic device 222, a communication device 223, a storage device 224, a positioning device 225, and a receiver 226, as shown in FIG. The data transmission device 220 includes, for example, a tablet, a portable terminal such as a mobile phone, and a computer. Information for the arithmetic unit 222 to execute processing is input to the input/output device 221 . Also, the input/output device 221 outputs the result of the processing executed by the arithmetic device 222 . The input/output device 221 includes various input devices and output devices, such as keyboards, mice, microphones, displays, speakers, and touch panels.
　通信装置２２３は、ネットワーク２０に電気的に接続され、ネットワーク２０を介して各々の装置との通信を行う。通信装置２２３は、作業管理装置１００から取得する信号を演算装置２２２に転送する。また、演算装置２２２が生成した信号を作業管理装置１００に転送する。通信装置２２３は、例えば、無線ＬＡＮ（Local　Area　Network）の送受信機、ＮＩＣ（Network　Interface　Card）、ＵＳＢ（Universal　Serial Bus）などの種々のインタフェースを含む。 The communication device 223 is electrically connected to the network 20 and communicates with each device via the network 20 . The communication device 223 transfers the signal acquired from the work management device 100 to the arithmetic device 222 . Also, the signal generated by the computing device 222 is transferred to the work management device 100 . The communication device 223 includes various interfaces such as a wireless LAN (Local Area Network) transceiver, NIC (Network Interface Card), and USB (Universal Serial Bus).
　測位装置２２５は、各時刻における自機の位置、例えば緯度と、経度とを測定する。測定された位置を表す位置情報は、演算装置２２２に送信される。測位装置２２５は、データ送信装置２２０が作業装置２００に設けられることにより、作業装置２００の各時刻における位置を測定する。測位装置２２５は、例えばＧＮＳＳ（Global　Navigation　Satellite　System）の受信機である。 The positioning device 225 measures the position of the aircraft at each time, such as latitude and longitude. Position information representing the measured position is sent to the computing device 222 . Positioning device 225 measures the position of work device 200 at each time by providing data transmission device 220 in work device 200 . The positioning device 225 is, for example, a GNSS (Global Navigation Satellite System) receiver.

The arithmetic device 222 of the data transmission device 220 shown in FIG. 3 executes a part of the work management method by reading and executing the data transmission program 400 when the engine of the work device 200 is activated.

FIG. Further, identification information of work device 200 representing work device 200 is also stored in storage device 224 . When the engine of the work device 200 is stopped, the data transmission section 250 transmits the operation information stored in the storage device 224 to the arithmetic device 120 of the work management device 100 .
　図５に示す作業管理装置１００の演算装置１２０は、例えば作業管理装置１００が起動したときに、作業管理プログラム４３０を読み出し実行する。作業管理プログラム４３０を実行することで、演算装置１２０は、作業管理方法の一部である図８Ａ、８Ｂに示す処理を実行する。ステップＳ１１０において、演算装置１２０で実現されるデータ記憶部１５０は、作業装置２００から稼働情報を受信して、受信した稼働情報を稼働データ４１０に格納する。 The computing device 120 of the work management device 100 shown in FIG. 5 reads and executes the work management program 430 when the work management device 100 is activated, for example. By executing the work management program 430, the computing device 120 executes the processes shown in FIGS. 8A and 8B, which are part of the work management method. In step S<b>110 , the data storage unit 150 implemented by the computing device 120 receives the operation information from the working device 200 and stores the received operation information in the operation data 410 .
　ステップＳ１２０おいて、データ補正部１６０は、格納された稼働情報において、隣接する記憶時刻に対応する識別情報４１４が変化する記憶時刻を抽出する。例えば、データ補正部１６０は、図６に示す稼働データ４１０に格納された稼働情報を、時刻情報４１２の表す記憶時刻の順番に抽出する。抽出された稼働情報に含まれる識別情報４１４（以下、抽出識別情報と呼ぶ）は、直前に抽出した稼働情報に含まれる識別情報４１４（以下、隣接識別情報と呼ぶ）と比較される。抽出識別情報が隣接識別情報と異なるとき、データ補正部１６０は、識別情報４１４が変化したと判定し、抽出識別情報に対応する時刻情報４１２（以下、変化時刻情報と呼び、変化時刻情報が表す記憶時刻を変化記憶時刻と呼ぶ）を抽出する。 In step S120, the data correction unit 160 extracts the storage time at which the identification information 414 corresponding to the adjacent storage time changes from the stored operating information. For example, the data correction unit 160 extracts the operation information stored in the operation data 410 shown in FIG. Identification information 414 included in the extracted operation information (hereinafter referred to as extracted identification information) is compared with identification information 414 included in the previously extracted operation information (hereinafter referred to as adjacent identification information). When the extracted identification information is different from the adjacent identification information, the data correction unit 160 determines that the identification information 414 has changed, and corrects the time information 412 corresponding to the extracted identification information (hereinafter referred to as change time information, where the change time information represents The stored time is called a changed stored time).
　図６に示す例において、第１稼働情報５１０に含まれる識別情報４１４の「－」は、受信不能を表す。受信不能は、図４に示すデータ送信装置２２０のデータ送信部２５０が稼働情報を記憶する時間間隔に発信機２１５から識別情報４１４を正常に受信できなかったことを表す。例えば、データ送信部２５０が記憶する時間間隔に識別情報４１４を受信しなかったとき、識別情報４１４は受信不能を表す。また、受信感度４１５が所定の値より小さいとき、正常に受信できなかったとして、識別情報４１４は受信不能を表す。 In the example shown in FIG. 6, "-" in the identification information 414 included in the first operation information 510 indicates unreceivable. Unreceivable indicates that the data transmission unit 250 of the data transmission device 220 shown in FIG. 4 could not normally receive the identification information 414 from the transmitter 215 during the time interval for storing the operation information. For example, when the identification information 414 is not received within the time interval stored by the data transmission unit 250, the identification information 414 indicates unreceivable. Further, when the reception sensitivity 415 is smaller than a predetermined value, the identification information 414 indicates that reception is not possible, assuming that reception was not possible normally.
　一方、図６に示す第１稼働情報５１０の直前の稼働情報に含まれる識別情報４１４は、「Ａ」を表す。このため、第１稼働情報５１０に含まれる識別情報４１４は、直前の稼働情報に含まれる識別情報４１４と異なるため、データ補正部１６０は、第１稼働情報５１０に含まれる時刻情報４１２から記憶時刻を抽出する。 On the other hand, the identification information 414 included in the operation information immediately preceding the first operation information 510 shown in FIG. 6 represents "A". Therefore, since the identification information 414 included in the first operation information 510 is different from the identification information 414 included in the immediately preceding operation information, the data correction unit 160 converts the time information 412 included in the first operation information 510 into the stored time. to extract
　図８Ａに示すステップＳ１３０において、データ補正部１６０は、識別情報４１４が変化する変化記憶時刻を抽出したかを判定する。データ補正部１６０は、変化記憶時刻を抽出したとき、ステップＳ１４０の処理を実行する。識別情報４１４が変化する変化記憶時刻が存在しないとき、データ補正部１６０は処理を終了する。例えば、図６に示す例において、第１稼働情報５１０において、識別情報４１４が変化しているため、データ補正部１６０はステップＳ１４０の処理を実行する。 At step S130 shown in FIG. 8A, the data correction unit 160 determines whether the change storage time at which the identification information 414 changes has been extracted. When the data correction unit 160 extracts the change storage time, the data correction unit 160 executes the process of step S140. When the change storage time at which the identification information 414 changes does not exist, the data correction unit 160 terminates the process. For example, in the example shown in FIG. 6, since the identification information 414 has changed in the first operation information 510, the data corrector 160 executes the process of step S140.
　図８Ａに示すステップＳ１４０において、データ補正部１６０は、変化後の識別情報４１４（以下、変化識別情報と呼ぶ）が受信不能を表すかを判定する。データ補正部１６０は、変化識別情報として、稼働データ４１０から抽出された変化記憶時刻に対応する識別情報４１４を抽出する。データ補正部１６０は、抽出された識別情報４１４である変化識別情報が受信不能を表さないとき、図８Ｂに示すステップＳ１６０を実行する。変化識別情報が受信不能を表すとき、データ補正部１６０は、図８Ａに示すステップＳ１５０の処理を実行する。図６に示す例において、第１稼働情報５１０に含まれる識別情報４１４が受信不能を表すため、データ補正部１６０は、ステップＳ１５０の処理を実行する。 In step S140 shown in FIG. 8A, the data correction unit 160 determines whether the identification information 414 after change (hereinafter referred to as change identification information) indicates unreceivability. Data correction unit 160 extracts identification information 414 corresponding to the change storage time extracted from operation data 410 as change identification information. Data corrector 160 executes step S160 shown in FIG. 8B when change identification information, which is extracted identification information 414, does not indicate unreceivability. When the change identification information indicates unreceivable, data correction section 160 executes the process of step S150 shown in FIG. 8A. In the example shown in FIG. 6, the identification information 414 included in the first operation information 510 indicates unreceivable, so the data correction unit 160 executes the process of step S150.
　図８Ａに示すステップＳ１５０において、データ補正部１６０は、変化識別情報を、変化記憶時刻に隣接する記憶時刻に対応する識別情報４１４に補正する。例えば、データ補正部１６０は、受信不能を表す識別情報４１４を、直前または直後の記憶時刻に対応する識別情報４１４に補正する。図６に示す例において、第１稼働情報５１０に含まれる識別情報４１４は、図９に示すように、直前の記憶時刻に対応する識別情報４１４である「Ａ」に補正される。また、第１稼働情報５１０に含まれる受信感度４１５も、直前の記憶時刻に対応する受信感度４１５である「－８６」に補正される。データ補正部１６０は、識別情報４１４を補正すると、ステップＳ１２０に戻って、処理を実行する。 In step S150 shown in FIG. 8A, the data correction unit 160 corrects the change identification information to the identification information 414 corresponding to the storage time adjacent to the change storage time. For example, the data correcting unit 160 corrects the identification information 414 indicating unreceivable to the identification information 414 corresponding to the storage time immediately before or after. In the example shown in FIG. 6, the identification information 414 included in the first operation information 510 is corrected to "A", which is the identification information 414 corresponding to the immediately previous storage time, as shown in FIG. Further, the reception sensitivity 415 included in the first operation information 510 is also corrected to "-86", which is the reception sensitivity 415 corresponding to the immediately preceding stored time. After correcting the identification information 414, the data correction unit 160 returns to step S120 and executes the process.
　変化後の変化識別情報が受信不能を表さないとき、図８Ｂに示すステップＳ１６０において、データ補正部１６０は、稼働データ４１０に基づき、抽出された変化記憶時刻に作業装置２００が移動しているかを判定する。データ補正部１６０は、抽出された変化記憶時刻に作業装置２００が移動していないと判定すると、図８Ａに示すステップＳ１２０に戻って、処理を実行する。抽出された変化記憶時刻に作業装置２００が移動していると判定すると、データ補正部１６０は、ステップＳ１７０の処理を実行する。 When the change identification information after the change does not indicate unreceivable, in step S160 shown in FIG. judge. When data correction unit 160 determines that work device 200 has not moved at the extracted change storage time, data correction unit 160 returns to step S120 shown in FIG. 8A and executes the processing. When determining that work device 200 is moving at the extracted change storage time, data correction unit 160 executes the process of step S170.
　例えば、データ補正部１６０は、変化記憶時刻に対応する位置情報４１３と、変化記憶時刻に隣接する記憶時刻に対応する位置情報４１３とに基づき、変化記憶時刻に作業装置２００が移動しているかを判定する。例えば、データ補正部１６０は、図９に示す稼働データ４１０から、変化記憶時刻に対応する位置情報４１３（以下、変化位置情報と呼ぶ）と、変化記憶時刻に隣接する記憶時刻に対応する位置情報４１３（以下、隣接位置情報と呼ぶ）とを抽出する。抽出された変化位置情報と隣接位置情報とが異なるとき、データ補正部１６０は、変化記憶時刻において作業装置２００が移動していると判定する。データ補正部１６０は、変化位置情報が表す位置と隣接位置情報が表す位置との距離が所定の閾値より大きいとき、抽出された記憶時刻において作業装置２００が移動していると判定してもよい。隣接位置情報は、変化記憶時刻を含む連続する複数の記憶時刻に対応する複数の位置情報４１３を含んでもよい。この場合、データ補正部１６０は、連続する複数の記憶時刻で表される期間のうち、所定の期間より長く、作業装置２００が継続して停止しているかを判定する。所定の時間より長く、作業装置２００が継続して停止していないとき、データ補正部１６０は、変化記憶時刻において作業装置２００が移動していると判定する。 For example, based on the position information 413 corresponding to the change storage time and the position information 413 corresponding to the storage time adjacent to the change storage time, the data correction unit 160 determines whether the work device 200 is moving at the change storage time. judge. For example, the data correction unit 160 extracts position information 413 (hereinafter referred to as change position information) corresponding to the change storage time and position information corresponding to the storage time adjacent to the change storage time from the operation data 410 shown in FIG. 413 (hereinafter referred to as adjacent position information) is extracted. When the extracted change position information and the adjacent position information are different, data correction unit 160 determines that work device 200 is moving at the change storage time. The data correction unit 160 may determine that the work device 200 is moving at the extracted storage time when the distance between the position indicated by the changed position information and the position indicated by the adjacent position information is greater than a predetermined threshold. . The adjacent position information may include a plurality of position information 413 corresponding to a plurality of consecutive storage times including the change storage time. In this case, the data correction unit 160 determines whether the work device 200 has been stopped continuously for a period longer than a predetermined period among the periods represented by a plurality of consecutive storage times. When work device 200 has not stopped continuously for longer than the predetermined time, data correction unit 160 determines that work device 200 is moving at the change storage time.
　図９に示す例において、データ補正部１６０は、ステップＳ１２０において、識別情報４１４が変化する記憶時刻に対応する稼働情報として、第２稼働情報５２０を抽出し、ステップＳ１３０、Ｓ１４０、Ｓ１６０の順番に実行する。ステップＳ１６０において、データ補正部１６０は、第２稼働情報５２０に含まれる位置情報４１３（以下、第２位置情報と呼ぶ）と、第２稼働情報５２０に含まれる記憶時刻（以下、第２記憶時刻と呼ぶ）に隣接する稼働情報の位置情報４１３とに基づき、作業装置２００が移動していると判定する。例えば、第２位置情報と、直前の稼働情報に含まれる位置情報４１３とを比較して、第２位置情報と、直前の稼働情報に含まれる位置情報４１３が異なるときに、データ補正部１６０は作業装置２００が移動していると判定する。また、データ補正部１６０は、第２位置情報から直前の稼働情報に含まれる位置情報４１３までの距離が所定の距離より大きいときに、作業装置２００が移動していると判定してもよい。 In the example shown in FIG. 9, in step S120, the data correction unit 160 extracts the second operation information 520 as operation information corresponding to the storage time at which the identification information 414 changes, and sequentially performs steps S130, S140, and S160. Run. In step S160, the data correction unit 160 sets the position information 413 included in the second operation information 520 (hereinafter referred to as second position information) to the storage time included in the second operation information 520 (hereinafter referred to as second storage time). ), it is determined that the work device 200 is moving. For example, by comparing the second location information and the location information 413 included in the immediately preceding operation information, when the second location information and the location information 413 included in the immediately preceding operation information are different, the data correction unit 160 It is determined that the work device 200 is moving. Further, the data correction unit 160 may determine that the work device 200 is moving when the distance from the second position information to the position information 413 included in the immediately preceding operation information is greater than a predetermined distance.
　図８Ｂに示すステップＳ１７０において、データ補正部１６０は、稼働データ４１０に基づき、対応する識別情報４１４が同じであり、所定の数以上連続した記憶時刻により表される基準期間を抽出する。例えば、データ補正部１６０は、識別情報４１４が同じであり、ステップＳ１２０で抽出された変化記憶時刻に最も近く、所定の数、例えば５以上連続した記憶時刻により表される基準期間を抽出する。基準期間は、変化記憶時刻よりも前、かつ、最も近い期間でもよい。 In step S170 shown in FIG. 8B, the data correction unit 160 extracts, based on the operation data 410, reference periods that have the same corresponding identification information 414 and that are represented by a predetermined number or more of consecutive storage times. For example, the data correction unit 160 extracts a reference period that has the same identification information 414, is closest to the change storage time extracted in step S120, and is represented by a predetermined number, for example, five or more consecutive storage times. The reference period may be the period preceding and closest to the change storage time.
　図９に示す例において、データ補正部１６０は、変化記憶時刻である第２稼働情報５２０の第２記憶時刻よりも前、かつ、最も近く、連続して５回以上同じ識別情報４１４を表す基準期間を抽出する。このため、データ補正部１６０は、第２稼働情報群５２５に表される期間を基準期間として抽出する。 In the example shown in FIG. 9 , the data correction unit 160 uses the reference that represents the same identification information 414 five times or more consecutively before and closest to the second storage time of the second operation information 520 that is the change storage time. Extract duration. Therefore, the data correction unit 160 extracts the period represented by the second operation information group 525 as the reference period.
　図８Ｂに示すステップＳ１８０において、データ補正部１６０は、抽出された基準期間から変化記憶時刻までの間、作業装置２００が連続して移動しているかを判定する。基準期間から変化記憶時刻までの間で、作業装置２００が停止している期間があるとき、データ補正部１６０は、図８Ａに示すステップＳ１２０に戻って、処理を実行する。基準期間から変化記憶時刻までの間、作業装置２００が連続して移動しているとき、データ補正部１６０は、図８Ｂに示すステップＳ１７０の処理を実行する。データ補正部１６０が作業装置２００の移動を判定する方法は、ステップＳ１６０の処理で説明した方法を用いる。例えば、データ補正部１６０は、基準期間から変化記憶時刻までの期間から、記憶時刻が互いに隣接する２つの稼働情報を抽出し、抽出された２つの稼働情報に基づき、作業装置２００が停止しているかを判定する。 In step S180 shown in FIG. 8B, the data correction unit 160 determines whether the working device 200 is continuously moving from the extracted reference period to the change storage time. When there is a period during which work device 200 is stopped between the reference period and the change storage time, data correction unit 160 returns to step S120 shown in FIG. 8A and executes the process. When work device 200 is continuously moving from the reference period to the change storage time, data correction unit 160 executes the process of step S170 shown in FIG. 8B. As the method for determining the movement of work device 200 by data correction unit 160, the method described in the process of step S160 is used. For example, the data correction unit 160 extracts two pieces of operation information whose storage times are adjacent to each other from the period from the reference period to the change storage time. determine whether there is
　図９に示す例において、データ補正部１６０は、第２稼働情報群５２５に対応する基準期間から第２稼働情報５２０に対応する第２記憶時刻までの間で、作業装置２００が連続して移動しているかを判定する。データ補正部１６０は、作業装置２００が連続して移動していると判定すると、ステップＳ１９０の処理を実行する。 In the example shown in FIG. 9 , the data correction unit 160 determines whether the work device 200 continuously moves during the period from the reference period corresponding to the second operation information group 525 to the second storage time corresponding to the second operation information 520. determine whether it is When the data correction unit 160 determines that the work device 200 is continuously moving, the data correction unit 160 executes the process of step S190.
　図８Ｂに示すステップＳ１９０において、データ補正部１６０は、変化記憶時刻に対応する変化識別情報を、基準期間に対応する識別情報４１４に補正する。変化識別情報が補正されると、データ補正部１６０は、図８Ａに示すステップＳ１２０に戻って、処理を実行する。 In step S190 shown in FIG. 8B, the data correction unit 160 corrects the change identification information corresponding to the change storage time to the identification information 414 corresponding to the reference period. After the change identification information is corrected, the data correction unit 160 returns to step S120 shown in FIG. 8A and executes the process.
　図９に示す例において、第２稼働情報５２０における識別情報４１４は、図１０に示すように、第２稼働情報群５２５における識別情報４１４である「Ａ」に補正される。データ補正部１６０は、ステップＳ１２０に戻って、処理を実行することで、第３稼働情報５３０は、第２稼働情報５２０と同様に処理されて、図１１に示すように、第３稼働情報５３０の識別情報４１４は、「Ａ」に補正される。 　In the example shown in FIG. 9, the identification information 414 in the second operation information 520 is corrected to "A", which is the identification information 414 in the second operation information group 525, as shown in FIG. The data correction unit 160 returns to step S120 and executes the process, so that the third operation information 530 is processed in the same manner as the second operation information 520, and as shown in FIG. 11, the third operation information 530 is corrected to "A".
　また、稼働データ４１０は、図１１の第４稼働情報５４０と第５稼働情報５５０とに示すように、同じ記憶時刻に異なる発信機２１５から識別情報４１４を受信する場合がある。この場合も、データ補正部１６０は、図８Ａに示すステップＳ１２０において、識別情報４１４が変化する記憶時刻に対応する稼働情報として、第５稼働情報５５０を抽出する。ここで、図１１に示す第５稼働情報５５０は、第４稼働情報５４０と比較されても、第４稼働情報５４０の示す記憶時刻の直前の稼働情報と比較されてもよい。データ補正部１６０は、抽出された第５稼働情報５５０に対応する記憶時刻（以下、第５記憶時刻と呼ぶ）を変化記憶時刻として、ステップＳ１３０、Ｓ１４０、Ｓ１６０の順番に実行する。 Also, the operating data 410 may receive identification information 414 from different transmitters 215 at the same storage time, as shown in the fourth operating information 540 and the fifth operating information 550 in FIG. In this case as well, the data correction unit 160 extracts the fifth operation information 550 as operation information corresponding to the storage time at which the identification information 414 changes in step S120 shown in FIG. 8A. Here, the fifth operation information 550 shown in FIG. 11 may be compared with the fourth operation information 540 or with operation information immediately before the storage time indicated by the fourth operation information 540 . The data correction unit 160 performs steps S130, S140, and S160 in order, using the storage time corresponding to the extracted fifth operation information 550 (hereinafter referred to as the fifth storage time) as the changed storage time.
　データ補正部１６０は、図８Ｂに示すステップＳ１７０において、変化記憶時刻である第５稼働情報５５０の第５記憶時刻よりも前、かつ、最も近く、連続して５回以上同じ識別情報４１４を表す基準期間を抽出する。このため、データ補正部１６０は、図１１に示す第５稼働情報群５５５に表される期間を基準期間として抽出する。第５稼働情報群５５５は、第４稼働情報５４０を含む期間でもよい。 In step S170 shown in FIG. 8B, the data correction unit 160 expresses the same identification information 414 consecutively five times or more before and closest to the fifth storage time of the fifth operation information 550, which is the change storage time. Extract the reference period. Therefore, the data correction unit 160 extracts the period represented by the fifth operation information group 555 shown in FIG. 11 as the reference period. The fifth operating information group 555 may be a period including the fourth operating information 540 .
　データ補正部１６０は、図８Ｂに示すステップＳ１８０、Ｓ１９０の処理を実行して、図１２に示すように、第５稼働情報５５０の識別情報４１４は、第５稼働情報群５５５の識別情報４１４である「Ａ」に補正される。その後、データ補正部１６０は、ステップＳ１２０に戻って、処理を実行し、変化記憶時刻が抽出されなくなると、処理を終了する。 The data correction unit 160 executes the processes of steps S180 and S190 shown in FIG. 8B, and as shown in FIG. Corrected to some "A". After that, data correction unit 160 returns to step S120, executes the process, and terminates the process when the change storage time is no longer extracted.
　このように、作業管理装置１００のデータ補正部１６０は、稼働データ４１０の稼働情報を補正することができる。 In this way, the data correction unit 160 of the work management device 100 can correct the operation information of the operation data 410.
　図８Ａ、８Ｂに示す処理が終了すると、作業管理方法は、図５に示す稼働データ４１０に基づき、作業データ４２０に登録される作業情報を判定する。具体的には、図４に示す作業判定部１７０は、補正された稼働データ４１０に基づき、作業情報、例えば作業期間、作業種別、作業領域などを判定して、判定された作業情報をデータ記憶部１５０に記憶する。作業判定部１７０は、例えば、作業装置２００が起動された時刻から作業装置２００が停止された時刻までを作業期間として判定する。また、作業判定部１７０は、作業装置２００の作業を開始する時刻と終了する時刻と、例えば作業装置２００に牽引される作業機械２１０が駆動する時刻と停止する時刻とに基づき、作業期間を判定してもよい。作業期間は、作業装置２００が圃場に入った時刻と圃場から出た時刻とに基づき判定されてもよい。また、作業期間は、作業装置２００のエンジンが始動する時刻と、作業装置２００が停止、例えばエンジンが停止する時刻とに基づき判定されてもよい。 When the processes shown in FIGS. 8A and 8B are completed, the work management method determines the work information registered in the work data 420 based on the operation data 410 shown in FIG. Specifically, the work determination unit 170 shown in FIG. 4 determines work information such as work period, work type, work area, etc., based on the corrected operation data 410, and stores the determined work information as data. Store in unit 150 . The work determination unit 170 determines, for example, the work period from the time when the work device 200 is activated to the time when the work device 200 is stopped. Further, the work determining unit 170 determines the work period based on the time when the work of the work device 200 is started and finished, and the time when the work machine 210 towed by the work device 200 is driven and stopped. You may The work period may be determined based on the time when the work device 200 enters the field and the time when it leaves the field. Also, the work period may be determined based on the time when the engine of the work device 200 starts and the time when the work device 200 stops, for example, the engine stops.
　作業領域は、判定された作業期間における作業装置２００の位置情報４１３に基づき、判定される。具体的には、作業判定部１７０は、稼働データ４１０の位置情報４１３に基づき、作業領域を判定する。例えば、作業領域は、位置情報４１３に表される位置を含む任意の閉じた図形、例えば多角形、矩形などで表される。例えば、作業領域は、取得した位置情報４１３により表される位置のすべてを囲むような図形で表される。 The work area is determined based on the position information 413 of the work device 200 during the determined work period. Specifically, the work determination unit 170 determines the work area based on the position information 413 of the operation data 410 . For example, the work area is represented by any closed figure including the position represented by the position information 413, such as a polygon, rectangle, or the like. For example, the work area is represented by a figure surrounding all the positions represented by the acquired position information 413 .
　作業種別は、判定された作業期間において作業装置２００に牽引された作業機械２１０、例えば作業機械２１０の種類または機種に基づき、判定される。具体的には、作業判定部１７０は、図２に示す稼働データ４１０の識別情報４１４に基づき、作業種別を判定する。データ記憶部１５０は、発信機２１５の識別情報４１４と、発信機２１５が設けられた作業機械２１０、例えば作業機械の種類、機種、シリアル番号などとを関連づけて記憶する。また、データ記憶部１５０は、作業機械２１０、例えば作業機械２１０の種類、機種、シリアル番号などと、この作業機械２１０を使用して行われる作業種別とを関連づけて記憶する。作業判定部１７０は、稼働データ４１０の識別情報４１４と、データ記憶部１５０に記憶された情報とから、作業種別を判定する。 The work type is determined based on the work machine 210 towed by the work device 200 during the determined work period, for example, the type or model of the work machine 210. Specifically, the work determination unit 170 determines the work type based on the identification information 414 of the operation data 410 shown in FIG. The data storage unit 150 associates and stores the identification information 414 of the transmitter 215 and the work machine 210 provided with the transmitter 215, for example, the type, model, serial number, and the like of the work machine. Further, the data storage unit 150 stores the work machine 210, for example, the type, model, serial number, etc. of the work machine 210 in association with the type of work performed using this work machine 210. FIG. The work determination unit 170 determines the work type based on the identification information 414 of the operation data 410 and information stored in the data storage unit 150 .
　このようにデータ記憶部１５０に記憶された作業情報は、図４に示す端末３００の表示部３５０により、端末３００の入出力装置３１０に表示される。例えば、端末３００は、ユーザの操作、例えば作業情報を表示するための操作に応じて、作業管理装置１００のデータ記憶部１５０に、作業情報を要求するための要求信号を生成する。データ記憶部１５０は、端末３００の表示部３５０からの要求信号に応じて、作業データ４２０に含まれる作業情報を表す応答信号を生成して、応答信号を端末３００の表示部３５０に送信する。端末３００の表示部３５０は、応答信号に基づき、作業情報を入出力装置３１０に表示する。ユーザは、入出力装置３１０を確認することにより、補正された稼働情報を用いて判定された作業情報を確認することができる。 The work information thus stored in the data storage unit 150 is displayed on the input/output device 310 of the terminal 300 by the display unit 350 of the terminal 300 shown in FIG. For example, the terminal 300 generates a request signal for requesting work information from the data storage unit 150 of the work management device 100 in response to a user's operation, for example, an operation for displaying work information. Data storage unit 150 generates a response signal representing work information included in work data 420 in response to a request signal from display unit 350 of terminal 300 and transmits the response signal to display unit 350 of terminal 300 . The display unit 350 of the terminal 300 displays the work information on the input/output device 310 based on the response signal. By checking the input/output device 310, the user can check the work information determined using the corrected operation information.
　また、作業管理装置１００は、稼働データ４１０に基づき、作業機械２１０の保管位置を判定してもよい。図２に示す作業機械２１０は、作業装置２００から取り外されて保管場所に置かれる。その後、作業装置２００が作業機械２１０から離れると、作業装置２００に設けられたデータ送信装置２２０の受信機２２６は、作業機械２１０に設けられた発信機２１５から離れ、発信機２１５の識別情報４１４を受信できなくなる。このため、受信機２２６が発信機２１５から識別情報４１４を受信できなくなったときから、図２に示す稼働データ４１０において、識別情報４１４は受信不能を表す。稼働データ４１０において、所定の期間連続して、識別情報４１４が受信不能であるときの位置情報４１３に基づき、作業機械２１０の保管位置が判定される。 Also, the work management device 100 may determine the storage position of the work machine 210 based on the operation data 410 . Work machine 210 shown in FIG. 2 is removed from work device 200 and placed in a storage location. Thereafter, when work device 200 moves away from work machine 210, receiver 226 of data transmission device 220 provided in work device 200 moves away from transmitter 215 provided in work machine 210, and identification information 414 of transmitter 215 is transmitted. will not be able to receive Therefore, when the receiver 226 becomes unable to receive the identification information 414 from the transmitter 215, the identification information 414 in the operation data 410 shown in FIG. In operation data 410, the storage position of work machine 210 is determined based on position information 413 when identification information 414 is unreceivable continuously for a predetermined period.
　例えば、図４に示すデータ補正部１６０は、稼働データ４１０において、所定の期間連続して、識別情報４１４が受信不能であるとき、識別情報４１４が受信不能に変化した記憶時刻を取得する。データ補正部１６０は、図２に示す稼働データ４１０において、取得した記憶時刻に対応する位置情報４１３を取得して、取得された位置情報４１３により表される位置を作業機械２１０の保管場所としてデータ記憶部１５０に記録する。図４に示すデータ記憶部１５０は、端末３００の表示部３５０からの要求に応じて、記録された作業機械２１０の保管場所を表す保管位置情報を送信する。端末３００の表示部３５０は、受信された作業機械２１０の保管場所を表す保管位置情報に基づき、作業機械２１０の保管位置を表示することができる。 For example, in the operation data 410, the data correction unit 160 acquires the stored time when the identification information 414 changed to be unreceivable when the identification information 414 is continuously unreceivable for a predetermined period. Data correction unit 160 acquires position information 413 corresponding to the acquired storage time in operation data 410 shown in FIG. Record in the storage unit 150 . Data storage unit 150 shown in FIG. 4 transmits storage location information representing the storage location of recorded work machine 210 in response to a request from display unit 350 of terminal 300 . Display unit 350 of terminal 300 can display the storage location of work machine 210 based on the received storage location information representing the storage location of work machine 210 .
（変形例）
　実施の形態において説明した構成は一例であり、機能を阻害しない範囲で構成を変更することができる。例えば、図８Ａに示すステップＳ１６０において、データ補正部１６０は、作業装置２００がステップＳ１２０において抽出された変化記憶時刻に移動しているかを判定できれば、任意の方法を用いてもよい。例えば、データ補正部１６０は、変化記憶時刻を含む連続する複数の稼働情報における位置情報４１３に基づき、作業装置２００が移動していると判定してもよい。データ補正部１６０は、例えば、稼働データ４１０に基づき、変化記憶時刻以前の所定の期間、例えば変化記憶時刻からその５分前までの期間における作業装置２００の複数の位置情報４１３を取得する。取得された複数の位置情報４１３に基づき、データ補正部１６０は、作業装置２００が移動しているかを判定する。 (Modification)
The configuration described in the embodiment is an example, and the configuration can be changed within a range that does not hinder the functions. For example, in step S160 shown in FIG. 8A, the data correction unit 160 may use any method as long as it can determine whether the work device 200 has moved to the change storage time extracted in step S120. For example, the data correction unit 160 may determine that the work device 200 is moving based on the position information 413 in a plurality of consecutive pieces of operation information including change storage times. For example, based on the operation data 410, the data correction unit 160 acquires a plurality of pieces of position information 413 of the work device 200 during a predetermined period before the change storage time, for example, a period from the change storage time to five minutes before the change storage time. Based on the acquired pieces of position information 413, the data correction unit 160 determines whether the work device 200 is moving.
　例えば、取得された複数の位置情報４１３が表す位置のうち、最も離れた２つの位置の間の距離が所定の距離より大きいとき、データ補正部１６０は、作業装置２００が移動していると判定する。 For example, when the distance between the two furthest positions among the positions represented by the acquired plurality of position information 413 is greater than a predetermined distance, the data correction unit 160 determines that the work device 200 is moving. do.
　また、データ補正部１６０は、複数の位置情報４１３から、対応する記憶時刻が互いに隣接する２つの位置情報４１３の組み合わせをすべて抽出する。抽出したすべての組み合わせについて、２つの位置情報４１３が表す位置の間の距離が算出される。算出された距離のうち、少なくとも１つが所定の距離より大きいとき、データ補正部１６０は、作業装置２００が移動していると判定してもよい。 In addition, the data correction unit 160 extracts all combinations of two pieces of position information 413 whose corresponding storage times are adjacent to each other from the plurality of pieces of position information 413 . The distance between the positions represented by the two pieces of position information 413 is calculated for all the extracted combinations. When at least one of the calculated distances is greater than a predetermined distance, the data corrector 160 may determine that the work device 200 is moving.
　図８Ｂに示すステップＳ１８０において、ステップＳ１６０と同様に、データ補正部１６０は、ステップＳ１７０において抽出された基準期間から変化記憶時刻までの間、作業装置２００が停止している期間があるかを判定できれば、任意の方法を用いてもよい。例えば、データ補正部１６０は、基準期間から変化記憶時刻までの間で、所定の期間以上、例えば５分間以上、作業装置２００が停止しているかを判定してもよい。データ補正部１６０は、所定の期間以上、作業装置２００が停止しているときに、作業装置２００が停止している期間があると判定する。所定の期間以上、作業装置２００が停止していないとき、データ補正部１６０は、作業装置２００が停止している期間がないと判定する。また、ステップＳ１８０における作業装置２００の移動を判定する方法は、ステップＳ１６０における判定方法と同じでもよく、異なってもよい。 In step S180 shown in FIG. 8B, similarly to step S160, data correction unit 160 determines whether there is a period during which work device 200 is stopped from the reference period extracted in step S170 to the change storage time. Any method may be used if possible. For example, the data correction unit 160 may determine whether the work device 200 has been stopped for a predetermined period or longer, for example, 5 minutes or longer, between the reference period and the change storage time. The data correction unit 160 determines that there is a period during which the work device 200 is stopped when the work device 200 is stopped for a predetermined period or longer. When work device 200 has not stopped for a predetermined period of time or more, data correction unit 160 determines that there is no period in which work device 200 has stopped. Also, the method for determining movement of work device 200 in step S180 may be the same as or different from the determination method in step S160.
　図４に示すデータ送信部２５０により送信される稼働情報の記憶時刻は、発信機２１５の識別情報４１４を記録した時刻を表す例を示したが、発信機２１５の識別情報４１４を受信した時刻に対応する時刻を表せれば、任意の形式で表されてもよい。例えば、記憶時刻は、発信機２１５の識別情報４１４を受信した時刻でもよい。 The storage time of the operation information transmitted by the data transmission unit 250 shown in FIG. 4 is the time when the identification information 414 of the transmitter 215 is recorded. Any format may be used as long as the corresponding time can be represented. For example, the stored time may be the time when the identification information 414 of the transmitter 215 was received.
　図８Ｂに示すステップＳ１７０からＳ１９０において、データ補正部１６０は、識別情報４１４をより確からしい識別情報４１４に補正できれば、任意の方法を用いてもよい。例えば、データ補正部１６０は、ステップＳ１２０で抽出された変化記憶時刻を含み、作業装置２００が移動し続けている期間を抽出して、判定した期間における識別情報４１４に基づき、変化記憶時刻に対応する変化識別情報を補正してもよい。 In steps S170 to S190 shown in FIG. 8B, the data correction unit 160 may use any method as long as the identification information 414 can be corrected to more probable identification information 414. For example, the data correction unit 160 extracts a period during which the work device 200 continues to move, including the change storage time extracted in step S120, and corresponds to the change storage time based on the identification information 414 in the determined period. You may correct|amend the change identification information which carries out.
　具体的には、データ補正部１６０は、稼働データ４１０に基づき、変化記憶時刻を含み、作業装置２００が移動し続けている期間を抽出する。作業装置２００が移動し続けているかを判定する方法は、図８Ｂに示すステップＳ１６０、またはステップＳ１７０と同じ方法を用いてもよい。抽出された期間における識別情報４１４に基づき、データ補正部１６０は、変化識別情報を補正する。例えば、変化識別情報は、抽出された期間における識別情報４１４のうち、最も多く受信機２２６に受信された識別情報４１４に補正される。 Specifically, based on the operation data 410, the data correction unit 160 extracts the period during which the work device 200 continues to move, including the change storage time. As a method of determining whether work device 200 continues to move, the same method as in step S160 or step S170 shown in FIG. 8B may be used. Based on the identification information 414 in the extracted period, the data corrector 160 corrects the change identification information. For example, the change identification information is corrected to the identification information 414 received by the receiver 226 the most among the identification information 414 in the extracted time period.
　以上において説明した実施の形態および変形例は一例であり、各実施の形態および変形例で説明した構成は、機能を阻害しない範囲で、任意に変更してもよく、または／および、任意に組み合わせてもよい。さらに、必要となる機能を実現できれば、実施の形態および変形例で説明した一部の機能を省略してもよい。例えば、図４に示す表示部３５０は、データ送信装置２２０で実現されてもよい。また、データ記憶部１５０と、データ補正部１６０とは、データ送信装置２２０で実現されてもよい。 The embodiments and modifications described above are examples, and the configurations described in the embodiments and modifications may be arbitrarily changed and/or combined as long as the functions are not hindered. may Furthermore, some of the functions described in the embodiment and modifications may be omitted as long as the required functions can be realized. For example, the display unit 350 shown in FIG. 4 may be implemented by the data transmission device 220 . Data storage unit 150 and data correction unit 160 may be realized by data transmission device 220 .
　データ補正部１６０は、受信機２２６が所定の数以上連続して同じ識別情報４１４を受信しているとき、この識別情報４１４が正しいと判定してもよい。この場合、図８Ｂに示すステップＳ１８０は省略されてもよい。 The data correction unit 160 may determine that the identification information 414 is correct when the receiver 226 continuously receives the same identification information 414 for a predetermined number or more. In this case, step S180 shown in FIG. 8B may be omitted.
