　この発明は、エレベーターの制御装置に関するものである。 This invention relates to an elevator control device.
　従来、１つの昇降路内に複数の乗りかごが配設されたいわゆるワンシャフトマルチカー方式のエレベーターの制御装置においては、同一の昇降路内にそれぞれ独立して運転される下かご及び上かごを配設したエレベーターにおいて、上下のかごのそれぞれに保守運転スイッチを設け、上下かごの一方で保守運転スイッチが操作されると、保守運転スイッチが操作されなかった方のかごを終端階へ走行させた後、そのかごを休止状態とするものが知られている（例えば、特許文献１参照）。 Conventionally, in a so-called one-shaft multi-car elevator control device in which a plurality of passenger cars are arranged in one hoistway, a lower car and an upper car that are operated independently in the same hoistway, respectively. In the installed elevator, a maintenance operation switch is provided for each of the upper and lower cars. When the maintenance operation switch is operated on one of the upper and lower cars, the car that has not been operated is moved to the final floor. Thereafter, there is known a method in which the car is put into a dormant state (see, for example, Patent Document 1).

　しかしながら、特許文献１に示された従来におけるエレベーターの制御装置は、１つの乗りかごを保守する際に、保守対象の乗りかごと同じ昇降路内の保守対象でない乗りかごの運転を休止してしまうために、エレベーターの運行効率が著しく低下してしまう。 However, when the conventional elevator control device disclosed in Patent Document 1 maintains a single car, it stops the operation of the maintenance target car in the same hoistway as well as the maintenance target car. For this reason, the operation efficiency of the elevator is significantly reduced.
　この発明は、このような課題を解決するためになされたもので、同一の昇降路内に複数の乗りかごがそれぞれ独立して昇降可能に配設されたワンシャフトマルチカー方式のエレベーターにおいて、ある乗りかごを保守する際に、保守対象の乗りかごと同一の昇降路内の保守対象でない乗りかごの運転を継続することができ、エレベーターの運行効率の低下を抑制することが可能であるエレベーターの制御装置を得るものである。 The present invention has been made to solve such a problem, and is a one-shaft multi-car type elevator in which a plurality of passenger cars are independently movable up and down in the same hoistway. When maintaining a car, it is possible to continue the operation of a car that is not subject to maintenance in the same hoistway as well as the car that is subject to maintenance, and it is possible to suppress a decrease in elevator operation efficiency. A control device is obtained.
　この発明に係るエレベーターの制御装置においては、同一の昇降路内に複数の乗りかごがそれぞれ独立して昇降可能に配設されたワンシャフトマルチカー方式のエレベーターの制御装置であって、前記乗りかごのそれぞれの運転を制御するかご制御手段と、保守運転の乗りかごの保守運転範囲を設定する保守運転範囲設定手段と、を備え、前記かご制御手段は、保守運転の乗りかごと同一の昇降路内の他の乗りかごが、当該保守運転の乗りかごの保守運転範囲内に進入しないように制御する構成とする。 The elevator control device according to the present invention is a one-shaft multi-car elevator control device in which a plurality of passenger cars are arranged in the same hoistway so that they can be moved up and down independently of each other. A car control means for controlling each operation of the vehicle and a maintenance operation range setting means for setting a maintenance operation range of the car for the maintenance operation, wherein the car control means has the same hoistway for each car for the maintenance operation. It is set as the structure which controls so that the other passenger car may not enter into the maintenance operation range of the passenger car in the maintenance operation.
　この発明に係るエレベーターの制御装置においては、同一の昇降路内に複数の乗りかごがそれぞれ独立して昇降可能に配設されたワンシャフトマルチカー方式のエレベーターにおいて、保守対象の乗りかごと同一の昇降路内の保守対象でない乗りかごの運転を継続することができ、エレベーターの運行効率の低下を抑制することが可能であるという効果を奏する。 In the elevator control device according to the present invention, in the one-shaft multi-car type elevator in which a plurality of cars are independently movable up and down in the same hoistway, the same car for maintenance is used. It is possible to continue the operation of the car that is not a maintenance object in the hoistway, and it is possible to suppress the decrease in the operation efficiency of the elevator.

FIGS. 1 to 3 relate to Embodiment 1 of the present invention. FIG. 1 is a diagram schematically showing the overall configuration of a one-shaft multi-car elevator, and FIG. FIG. 3 is a block diagram showing the configuration of the control device, and FIG. 3 is a flowchart showing the operation of the one-shaft multi-car elevator control device.
　図１において、エレベーターが設置される建築物内に立設された図示しない昇降路内には、乗客や荷物等を積載して昇降する上かご１ａが配設されている。この上かご１ａの上端には上かご用ロープ２ａの一端が連結されている。この上かご用ロープ２ａの他端は上かご用釣合い重り３ａの上端に連結されている。上かご用釣合い重り３ａは昇降路内に昇降自在に配設されている。 Referring to FIG. 1, an upper car 1a that lifts and lowers passengers, luggage, etc. is disposed in a hoistway (not shown) standing in a building where an elevator is installed. One end of an upper car rope 2a is connected to the upper end of the upper car 1a. The other end of the upper car rope 2a is connected to the upper end of the upper car counterweight 3a. The upper car counterweight 3a is disposed in the hoistway so as to be raised and lowered.
　上かご用ロープ２ａの中間部は、昇降路の頂部に設けられた図示しない機械室内に設置された上かご用巻上機４ａの駆動シーブに巻き掛けられている。このようにして、上かご１ａ及び上かご用釣合い重り３ａは、上かご用ロープ２ａによって昇降路内で互いに相反する方向に昇降自在なつるべ状に吊持されている。 The intermediate portion of the upper car rope 2a is wound around the drive sheave of the upper car hoist 4a installed in a machine room (not shown) provided at the top of the hoistway. In this way, the upper car 1a and the upper car counterweight 3a are suspended by the upper car rope 2a in a slidable manner that can be raised and lowered in opposite directions in the hoistway.
　昇降路内には、上かご１ａに加え、下かご１ｂも昇降自在に配設されている。下かご１ｂの下部には、下かご用吊車５が取り付けられている。この下かご用吊車５には、下かご用ロープ２ｂの一端側が巻き掛けられている。そして、この下かご用ロープ２ｂの当該一端側の端部は昇降路内の頂部の所定の箇所に固定される。下かご用ロープ２ｂの他端は下かご用釣合い重り３ｂの上端に連結される。下かご用釣合い重り３ｂは昇降路内に昇降自在に配設されている。 In the hoistway, in addition to the upper car 1a, a lower car 1b is also arranged to be raised and lowered. A lower car suspension wheel 5 is attached to the lower part of the lower car 1b. One end of the lower car rope 2b is wound around the lower car suspension wheel 5. And the edge part of the said one end side of this lower cage rope 2b is fixed to the predetermined | prescribed location of the top part in a hoistway. The other end of the lower car rope 2b is connected to the upper end of the lower car counterweight 3b. The counter weight 3b for the lower car is disposed in the hoistway so as to be movable up and down.
　下かご用ロープ２ｂにおける下かご用吊車５に巻き掛けられた箇所と下かご用釣合い重り３ｂとの間の部分は、中間部は、昇降路の頂部の機械室内に設置された下かご用巻上機４ｂの駆動シーブに巻き掛けられている。このようにして、下かご１ｂ及び下かご釣合い重り４ｂも、昇降路内で互いに相反する方向に昇降自在に吊持されている。 The portion between the portion of the lower car rope 2b wound around the lower car suspension wheel 5 and the lower car counterweight 3b is the lower car winding installed in the machine room at the top of the hoistway. It is wound around the drive sheave of the upper machine 4b. In this way, the lower car 1b and the lower car counterweight 4b are also suspended so as to be movable up and down in directions opposite to each other in the hoistway.
　上かご１ａは昇降路内において下かご１ｂから見て相対的に上側に配設されている。したがって、上かご１ａは常に昇降路における下かご１ｂよりも上側にあり、逆に下かご１ｂは上かご１ａよりも常に昇降路における下側にある。このように、この発明に係るエレベーターの制御装置が制御対象とするエレベーターは、同一の昇降路内に複数のかごである上かご１ａ及び下かご１ｂがそれぞれ独立して昇降することができるように配設されたワンシャフトマルチカー方式のエレベーターである。 The upper car 1a is disposed relatively upward in the hoistway as viewed from the lower car 1b. Therefore, the upper car 1a is always above the lower car 1b in the hoistway, and conversely, the lower car 1b is always lower than the upper car 1a in the hoistway. As described above, the elevator controlled by the elevator control device according to the present invention is configured such that the upper car 1a and the lower car 1b, which are a plurality of cars, can be raised and lowered independently in the same hoistway. This is an arranged one-shaft multi-car type elevator.
　上かご１ａ及び／又は下かご１ｂが停止可能である建物の複数の階床のそれぞれには、上かご１ａ及び／又は下かご１ｂに乗客が乗降するための乗場６が設けられている。ここでは、複数の乗場６として、上から順に第１の乗場６ａ、第２の乗場６ｂ、第３の乗場６ｃ、第４の乗場６ｄ及び第５の乗場６ｅの５つを示す。ただし、この５つの乗場は例として示したものであり、複数の乗場６の数は５つに限られない。 On each of the floors of the building where the upper car 1a and / or the lower car 1b can be stopped, a landing 6 is provided for passengers to get on and off the upper car 1a and / or the lower car 1b. Here, as the plurality of halls 6, five of the first hall 6 a, the second hall 6 b, the third hall 6 c, the fourth hall 6 d, and the fifth hall 6 e are shown in order from the top. However, these five halls are shown as examples, and the number of the plurality of halls 6 is not limited to five.
　各乗場６には、乗客が所望する方向（上方向又は下方向）への乗場呼びを登録するための図示しない乗場呼びボタンが設置されている。また、上かご１ａ及び下かご１ｂのかご室内には、かご内の乗客が所望する行先階への行先階呼びを登録するための図示しない行先階ボタンが設置されている。 Each hall 6 is provided with a hall call button (not shown) for registering a hall call in the direction desired by the passenger (upward or downward). A destination floor button (not shown) for registering a destination floor call to a destination floor desired by a passenger in the car is installed in the car room of the upper car 1a and the lower car 1b.
　上かご１ａ及び下かご１ｂの運転は、それぞれ上かご制御装置１０ａ及び下かご制御装置１０ｂにより制御される。上かご制御装置１０ａ及び下かご制御装置１０ｂを含むエレベーターの制御装置の機能的な構成を図２に示す。 The operation of the upper car 1a and the lower car 1b is controlled by the upper car control device 10a and the lower car control device 10b, respectively. FIG. 2 shows a functional configuration of the elevator control device including the upper car control device 10a and the lower car control device 10b.
　上かご制御装置１０ａは、上かご駆動部１１ａ及び上かご位置検出部１２ａを備える。上かご駆動部１１ａは、上かご用巻上機４ａへと駆動信号を出力することで、上かご１ａの昇降路内における昇降動作の駆動制御を行う。上かご位置検出部１２ａは、昇降路内における上かご１ａの位置を検出する。 The upper car control device 10a includes an upper car driving unit 11a and an upper car position detecting unit 12a. The upper car drive unit 11a outputs a drive signal to the upper car hoist 4a, thereby performing drive control of the lifting operation in the hoistway of the upper car 1a. The upper car position detector 12a detects the position of the upper car 1a in the hoistway.
　同様に、下かご制御装置１０ｂは、下かご駆動部１１ｂ及び下かご位置検出部１２ｂを備える。下かご駆動部１１ｂは、下かご用巻上機４ｂへと駆動信号を出力することで、下かご１ｂの昇降路内における昇降動作の駆動制御を行う。下かご位置検出部１２ｂは、昇降路内における下かご１ｂの位置を検出する。 Similarly, the lower car control device 10b includes a lower car driving unit 11b and a lower car position detecting unit 12b. The lower car drive unit 11b outputs a drive signal to the lower car hoist 4b, thereby performing drive control of the raising / lowering operation in the hoistway of the lower car 1b. The lower car position detector 12b detects the position of the lower car 1b in the hoistway.
　上かご位置検出部１２ａ及び下かご位置検出部１２ｂにおけるかご位置の検出は、例えば、上かご用巻上機４ａ又は下かご用巻上機４ｂの駆動シーブの回転数（回転量）から算出することで行うことができる。あるいは、昇降路内に設置された図示しない着床プレートの検出信号に基づいてかご位置を検出することもできる。 The detection of the car position in the upper car position detection unit 12a and the lower car position detection unit 12b is calculated from, for example, the rotational speed (rotation amount) of the drive sheave of the upper car hoist 4a or the lower car hoist 4b. Can be done. Alternatively, the car position can be detected based on a detection signal of a landing plate (not shown) installed in the hoistway.
　上かご制御装置１０ａは、通常運転モード及び保守運転モードの少なくとも２つの運転モードを含む複数の運転モードを切り替えながら、現在選択されている運転モードに従って上かご１ａの運転を制御する。通常運転モードは、主に通常時に選択される運転モードである。この通常運転モードにおいては、上かご制御装置１０ａは、前述した乗場呼びボタン及び行先階ボタンの操作により登録された呼びに応答して、上かご１ａを各階床の乗場６に走行・停止させる。 The upper car control device 10a controls the operation of the upper car 1a according to the currently selected operation mode while switching a plurality of operation modes including at least two operation modes of the normal operation mode and the maintenance operation mode. The normal operation mode is an operation mode selected mainly during normal operation. In this normal operation mode, the upper car control device 10a causes the upper car 1a to run and stop at the hall 6 of each floor in response to the call registered by operating the hall call button and the destination floor button described above.
　通常運転モード中において、エレベーターの保守員により上かご用保守運転選択部２０ａが操作されて保守運転モードが選択されると、上かご制御装置１０ａは上かご１ａの運転モードを、通常運転モードから保守運転モードへと切り替える。保守運転モードにおいては、上かご制御装置１０ａは、保守員による操作に基づいて上かご１ａの運転を制御するようになる。保守運転モードとなった上かご１ａは、原則として乗客による乗場呼びボタンや行先階ボタンの操作により登録された呼びに応答しなくなる。 In the normal operation mode, when the maintenance operation mode for the upper car is operated by the elevator maintenance staff to select the maintenance operation mode, the upper car control device 10a changes the operation mode of the upper car 1a from the normal operation mode. Switch to maintenance operation mode. In the maintenance operation mode, the upper car control device 10a controls the operation of the upper car 1a based on the operation by the maintenance staff. In principle, the upper car 1a in the maintenance operation mode does not respond to calls registered by the passengers operating the hall call buttons and the destination floor buttons.
　上かご１ａの保守運転モードにおいては、保守運転において上かご１ａが走行可能な階床の範囲である保守運転範囲が設定される。この上かご１ａの保守運転範囲を設定するために上かご用保守運転範囲設定部２１ａが備えられている。この上かご用保守運転範囲設定部２１ａは、上かご用保守運転範囲記憶部２２ａ及び上かご用設定モード選択部２３ａを備えている。 In the maintenance operation mode of the upper car 1a, a maintenance operation range that is a floor range in which the upper car 1a can travel in the maintenance operation is set. In order to set the maintenance operation range of the upper car 1a, a maintenance operation range setting unit 21a for the upper car is provided. The upper car maintenance operation range setting unit 21a includes an upper car maintenance operation range storage unit 22a and an upper car setting mode selection unit 23a.
　上かご用保守運転範囲記憶部２２ａには、上かご１ａの保守スケジュールとともに、それぞれの保守スケジュールにおける上かご１ａの保守運転範囲が予め記憶されている。上かご用設定モード選択部２３ａは、上かご１ａの保守運転範囲の設定モードを選択するためのものである。保守運転範囲の設定モードには、自動設定モードと手動設定モードの２つがある。自動設定モードは、上かご１ａの保守運転範囲を上かご用保守運転範囲記憶部２２ａに記憶されているものに自動的に設定するモードである。手動設定モードは、上かご１ａ保守運転範囲を保守員が手動で入力したものに設定するモードである。 In the upper car maintenance operation range storage unit 22a, the maintenance operation range of the upper car 1a in each maintenance schedule is stored in advance together with the maintenance schedule of the upper car 1a. The upper car setting mode selection unit 23a is for selecting a setting mode of the maintenance operation range of the upper car 1a. There are two maintenance operation range setting modes: an automatic setting mode and a manual setting mode. The automatic setting mode is a mode in which the maintenance operation range of the upper car 1a is automatically set to the one stored in the upper car maintenance operation range storage unit 22a. The manual setting mode is a mode in which the maintenance operation range of the upper car 1a is set to one manually input by the maintenance staff.
　保守運転範囲の設定モードが手動設定モードである場合に保守員が所望の保守運転範囲を入力するために、上かご用保守運転範囲入力部２４ａが備えられている。前述したように、乗場呼びボタンは、通常運転モード時において、乗客が乗場呼びを登録するためのボタンとして設置されている。そして、この乗場呼びボタンは、保守運転モード時に保守運転範囲の手動設定モードが選択されている場合には、保守員が所望する保守運転範囲を指定するためのボタンとして機能するようになっている。 When the maintenance operation range setting mode is the manual setting mode, a maintenance operation range input unit 24a for the upper car is provided for a maintenance worker to input a desired maintenance operation range. As described above, the hall call button is installed as a button for the passenger to register the hall call in the normal operation mode. The hall call button functions as a button for designating a maintenance operation range desired by the maintenance staff when the maintenance operation range manual setting mode is selected in the maintenance operation mode. .
　上かご用保守運転選択部２０ａにより保守運転モードが選択され、かつ、上かご用設定モード選択部２３ａにより手動設定モードが選択されている場合には、乗場呼びボタンの操作信号は、上かご用保守運転範囲入力部２４ａへと入力される。そして、上かご用保守運転範囲入力部２４ａは、入力された乗場呼びボタンの操作信号を、上かご１ａの保守運転範囲の指定として解釈する。 When the maintenance operation mode is selected by the upper car maintenance operation selection unit 20a and the manual setting mode is selected by the upper car setting mode selection unit 23a, the operation signal of the hall call button is for the upper car. It is input to the maintenance operation range input unit 24a. Then, the upper car maintenance operation range input unit 24a interprets the input operation signal of the hall call button as designation of the maintenance operation range of the upper car 1a.
　こうして、保守運転モード時に保守運転範囲の手動設定モードが選択されている場合には、保守員が乗場呼びボタンを操作することにより、手動で保守運転範囲を設定することができる。なお、ここでは、保守運転範囲の手動設定に乗場呼びボタンを利用する例について説明したが、かご内の行先階ボタンを利用するようにしてもよいし、制御盤内等に保守運転範囲設定用の専用ボタンを設けるようにしてもよい。 Thus, when the maintenance operation range manual setting mode is selected in the maintenance operation mode, the maintenance operator can manually set the maintenance operation range by operating the hall call button. In this example, the landing call button is used for manual setting of the maintenance operation range. However, the destination floor button in the car may be used, or the maintenance operation range may be set in the control panel. A dedicated button may be provided.
　上かご用保守運転選択部２０ａにより上かご１ａの運転モードとして保守運転モードが選択されると、上かご用保守運転範囲設定部２１ａは、当該保守運転モードにおける上かご１ａの保守運転範囲を設定する。この保守運転範囲の設定に際し、上かご用設定モード選択部２３ａにより自動設定モードが選択されている場合には、上かご用保守運転範囲設定部２１ａは、上かご用保守運転範囲記憶部２２ａに記憶されている保守運転範囲を取得する。そして、上かご用保守運転範囲設定部２１ａは、上かご１ａの保守運転範囲を上かご用保守運転範囲記憶部２２ａから取得したものに設定する。 When the maintenance operation mode is selected as the operation mode of the upper car 1a by the upper car maintenance operation selection unit 20a, the upper car maintenance operation range setting unit 21a sets the maintenance operation range of the upper car 1a in the maintenance operation mode. To do. When the automatic operation mode is selected by the upper car setting mode selection unit 23a when setting the maintenance operation range, the upper car maintenance operation range setting unit 21a stores the upper car maintenance operation range storage unit 22a. Acquire the stored maintenance operation range. Then, the upper car maintenance operation range setting unit 21a sets the maintenance operation range of the upper car 1a to the one acquired from the upper car maintenance operation range storage unit 22a.
　一方、保守運転範囲の設定に際し、上かご用設定モード選択部２３ａにより手動設定モードが選択されている場合には、上かご用保守運転範囲設定部２１ａは、上かご用保守運転範囲入力部２４ａに入力されたボタン操作信号等により指定されたものに、上かご１ａの保守運転範囲を設定する。上かご制御装置１０ａは、こうして上かご用保守運転範囲設定部２１ａにより設定された保守運転範囲に従って上かご１ａの保守運転を制御する。 On the other hand, when setting the maintenance operation range, if the manual setting mode is selected by the upper car setting mode selection unit 23a, the upper car maintenance operation range setting unit 21a displays the upper car maintenance operation range input unit 24a. The maintenance operation range of the upper car 1a is set to the one designated by the button operation signal or the like input to the. The upper car control device 10a controls the maintenance operation of the upper car 1a in accordance with the maintenance operation range thus set by the upper car maintenance operation range setting unit 21a.
　上かご制御装置１０ａは、上かご用保守運転範囲設定部２１ａにより設定された上かご１ａの保守運転範囲に関する情報を、下かご制御装置１０ｂへと送信する。下かご制御装置１０ｂは、上かご制御装置１０ａから送信された情報に基づいて、下かご位置検出部１２ｂにより検出された下かご１ｂの位置が、上かご１ａの保守運転範囲内に入っているか否かを判定する。下かご１ｂの位置が上かご１ａの保守運転範囲内に入っている場合には、下かご制御装置１０ｂは、下かご１ｂが上かご１ａの保守運転範囲内にある旨を上かご制御装置１０ａへと送信する。 The upper car control device 10a transmits information related to the maintenance operation range of the upper car 1a set by the upper car maintenance operation range setting unit 21a to the lower car control device 10b. Whether the position of the lower car 1b detected by the lower car position detection unit 12b is within the maintenance operation range of the upper car 1a based on the information transmitted from the upper car control device 10a. Determine whether or not. When the position of the lower car 1b is within the maintenance operation range of the upper car 1a, the lower car control device 10b indicates that the lower car 1b is within the maintenance operation range of the upper car 1a. Send to.
　下かご制御装置１０ｂから下かご１ｂが上かご１ａの保守運転範囲内にある旨を上かご制御装置１０ａが受け取ると、上かご駆動部１１ａは、上かご１ａの走行を阻止する。また、上かご用報知部２５ａにより、上かご１ａの保守運転操作を行っている保守員に対して、下かご１ｂが上かご１ａの保守運転範囲内にある旨を報知する。この上かご用報知部２５ａは、例えば、スピーカー等を用いてブザー音及び／又は音声を鳴動するようにしてもよいし、ディスプレイ等の表示装置にメッセージ等を表示したり、ランプを点灯等したりするようにしてもよい。また、これらの報知方法を併用するようにしてもよい。 When the upper car control device 10a receives from the lower car control device 10b that the lower car 1b is within the maintenance operation range of the upper car 1a, the upper car driving unit 11a prevents the upper car 1a from traveling. Further, the upper car notifying unit 25a notifies the maintenance personnel who are performing the maintenance operation of the upper car 1a that the lower car 1b is within the maintenance operation range of the upper car 1a. The upper car notifying unit 25a may be configured to sound a buzzer sound and / or sound using a speaker or the like, display a message or the like on a display device such as a display, or turn on a lamp. You may make it do. Moreover, you may make it use these notification methods together.
　このようにして、下かご１ｂの位置が上かご１ａの保守運転範囲内に入っている場合には、上かご１ａの走行は阻止される。したがって、下かご１ｂの位置が上かご１ａの保守運転範囲内にある限りは、上かご１ａは走行することができないことになり、上かご１ａを保守運転とした当初の目的が達成できないおそれがある。そこで、下かご制御装置１０ｂにより下かご１ｂの位置が上かご１ａの保守運転範囲内に入っていると判定された場合、下かご駆動部１１ｂは、下かご１ｂ内に乗客がいない状態になり次第、下かご１ｂを上かご１ａの保守運転範囲外へと走行させる。 Thus, when the position of the lower car 1b is within the maintenance operation range of the upper car 1a, the upper car 1a is prevented from traveling. Therefore, as long as the position of the lower car 1b is within the maintenance operation range of the upper car 1a, the upper car 1a cannot travel, and there is a possibility that the original purpose of the upper car 1a as the maintenance operation cannot be achieved. is there. Therefore, when the lower car control device 10b determines that the position of the lower car 1b is within the maintenance operation range of the upper car 1a, the lower car driving unit 11b enters a state in which there are no passengers in the lower car 1b. The lower car 1b is made to travel outside the maintenance operation range of the upper car 1a.
　下かご１ｂ内に乗客がいない状態になったか否かは、例えば、下かご１ｂについて次の行先階が登録されていない状態になったか否かにより判断することができる。あるいは、下かご１ｂ内の荷重を検出する秤装置の検出に基づいて判断することもできる。さらに、下かご１ｂ内の状況を撮影するカメラ装置により撮影された画像に基づいて判断することもできる。また、これらの行先階の登録状況、秤装置及びカメラ装置に利用した手法の複数を組み合わせてもよい。 Whether or not there is no passenger in the lower car 1b can be determined, for example, by whether or not the next destination floor has been registered for the lower car 1b. Or it can also judge based on the detection of the scale apparatus which detects the load in the lower cage | basket | car 1b. Furthermore, it can also be determined based on an image photographed by a camera device that photographs the situation in the lower car 1b. Moreover, you may combine the registration status of these destination floors, the method utilized for the scale apparatus and the camera apparatus.
　そして、下かご１ｂが上かご１ａの保守運転範囲外へと出ると、上かご駆動部１１ａによる上かご１ａの走行阻止が解除される。これは、下かご位置検出部１２ｂにより下かご１ｂが上かご１ａの保守運転範囲内にある場合に、下かご制御装置１０ｂから上かご制御装置１０ａへと検出信号が送信され続けるようにし、上かご駆動部１１ａは、下かご制御装置１０ｂからの検出信号を受信している間は上かご１ａの走行を阻止し、下かご制御装置１０ｂからの検出信号を受信しなくなった後に上かご１ａの走行阻止を解除することで実現できる。 When the lower car 1b goes out of the maintenance operation range of the upper car 1a, the upper car 1a is prevented from being prevented from traveling by the upper car driving unit 11a. This is because when the lower car 1b is within the maintenance operation range of the upper car 1a by the lower car position detecting unit 12b, a detection signal is continuously transmitted from the lower car control device 10b to the upper car control device 10a. The car driving unit 11a prevents the upper car 1a from running while receiving the detection signal from the lower car control device 10b, and after the car has stopped receiving the detection signal from the lower car control device 10b, This can be achieved by canceling the running prevention.
　あるいは、下かご位置検出部１２ｂにより下かご１ｂが上かご１ａの保守運転範囲外に出たことが検出された場合に、下かご位置検出部１２ｂにより下かご１ｂが上かご１ａの保守運転範囲内にある場合に、下かご制御装置１０ｂから上かご制御装置１０ａへと下かご１ｂが上かご１ａの保守運転範囲外に出た旨の信号を送信するようにし、上かご駆動部１１ａは、下かご制御装置１０ｂからの下かご１ｂが上かご１ａの保守運転範囲外に出た旨の信号を受信した場合に、上かご１ａの走行阻止を解除するようにすることでも実現できる。 Alternatively, when the lower car position detection unit 12b detects that the lower car 1b is out of the maintenance operation range of the upper car 1a, the lower car position detection unit 12b detects that the lower car 1b is in the maintenance operation range of the upper car 1a. The lower car control device 10b transmits a signal indicating that the lower car 1b has gone out of the maintenance operation range of the upper car 1a to the upper car control device 10a. This can also be realized by canceling the traveling inhibition of the upper car 1a when the lower car 1b from the lower car control device 10b receives a signal indicating that the car is out of the maintenance operation range of the upper car 1a.
　以上で説明した、上かご１ａの保守運転範囲の設定と、下かご１ｂの保守運転範囲外への退避について、具体例を挙げて説明する。例えば、上かご用保守運転範囲設定部２１ａにより上かご１ａの保守運転範囲が、図１の第２の乗場６ｂ及び第３の乗場６ｃの階床に設定されたとする。そして、この際に、下かご１ｂが第３の乗場６ｃの階床に停止していた場合、下かご１ｂは上かご１ａの保守運転範囲内にあるため、上かご１ａの走行が阻止される。 The above-described setting of the maintenance operation range of the upper car 1a and retreating the lower car 1b out of the maintenance operation range will be described with specific examples. For example, it is assumed that the maintenance operation range of the upper car 1a is set on the floors of the second hall 6b and the third hall 6c in FIG. 1 by the maintenance operation range setting unit 21a for the upper car. At this time, if the lower car 1b is stopped on the floor of the third landing 6c, the lower car 1b is within the maintenance operation range of the upper car 1a, and therefore the upper car 1a is prevented from traveling. .
　また、下かご１ｂ内に乗客がいないことが確認されると、下かご駆動部１１ｂは、下かご１ｂを第４の乗場６ｄの階床へと走行させる。そして、下かご１ｂを第４の乗場６ｄの階床まで移動して、上かご１ａの保守運転範囲内にないことが確認されると、上かご１ａは走行可能となる。 If it is confirmed that there are no passengers in the lower car 1b, the lower car driving unit 11b causes the lower car 1b to travel to the floor of the fourth landing 6d. When the lower car 1b is moved to the floor of the fourth landing 6d and it is confirmed that it is not within the maintenance operation range of the upper car 1a, the upper car 1a can run.
　なお、上かご１ａは常に下かご１ｂよりも上方にあることから、上かご１ａと上端階との間には、上かご１ａの他のかごは存在しない。したがって、上かご１ａの保守運転範囲を設定する際に、上かご１ａの現在位置から上端階までの範囲を保守運転範囲に含むようにしても、当該範囲に上かご１ａの他のかご（下かご１ｂ）が入ってしまうことがない。 Since the upper car 1a is always above the lower car 1b, there is no other car in the upper car 1a between the upper car 1a and the upper floor. Therefore, when the maintenance operation range of the upper car 1a is set, even if the range from the current position of the upper car 1a to the upper floor is included in the maintenance operation range, the other car (lower car 1b) is included in the range. ) Will not enter.
　このような事情から、上かご用保守運転範囲設定部２１ａは、上かご１ａの保守運転範囲を設定する際に、上かご用保守運転範囲記憶部２２ａに記憶されている保守運転範囲や上かご用保守運転範囲入力部２４ａにより入力された保守運転範囲にかかわらず、自動的に上かご１ａの現在位置から上端階までの範囲を保守運転範囲に含むように設定してもよい。言い換えれば、上かご用保守運転範囲設定部２１ａは、上かご１ａの保守運転範囲の上端を常に上端階に設定する。 For this reason, when the maintenance operation range setting unit 21a for the upper car sets the maintenance operation range for the upper car 1a, the maintenance operation range and the upper car stored in the maintenance operation range storage unit 22a for the upper car are set. Regardless of the maintenance operation range input by the maintenance operation range input unit 24a, the range from the current position of the upper car 1a to the upper floor may be automatically included in the maintenance operation range. In other words, the upper car maintenance operation range setting unit 21a always sets the upper end of the maintenance operation range of the upper car 1a to the upper floor.
　このようにすることで、保守運転しない他のかご（下かご１ｂ）へ影響を与えることなく、上かご１ａの保守運転範囲を広くすることができる。また、保守運転範囲の手動設定モードにおいて、保守員は保守運転範囲の上端の階床を指定する必要がなくなり、保守運転範囲の下端の階床のみを指定すればよくなるため、利便性を向上することができる。 By doing in this way, the maintenance operation range of the upper car 1a can be widened without affecting other cars (the lower car 1b) that are not in maintenance operation. In the maintenance operation range manual setting mode, maintenance personnel do not need to specify the upper floor of the maintenance operation range, and only the lower floor of the maintenance operation range needs to be specified, which improves convenience. be able to.
　なお、ここでは、同一の昇降路内に２つの乗りかごである上かご１ａ及び下かご１ｂが配設されている場合について説明している。同一の昇降路内に配設される乗りかごの数について一般化し、同一の昇降路内に複数の乗りかごが配設されている場合であれば、保守運転に切り替えられた乗りかごの現在位置から終端階（上端階又は下端階）までの間に他の乗りかごが存在しない場合には、当該保守運転に切り替えられた乗りかごの保守運転範囲の一端を他の乗りかごが存在しない側の終端階に設定するようにすればよい。 In addition, here, the case where two upper cars 1a and lower cars 1b are arranged in the same hoistway is described. If the number of cars in the same hoistway is generalized, and there are multiple cars in the same hoistway, the current position of the car that has been switched to maintenance operation If there is no other car between the first floor and the last floor (upper floor or lower floor), one end of the maintenance operation range of the car that has been switched to the maintenance operation is the side where no other car exists. It may be set to the end floor.
　下かご制御装置１０ｂも、上かご制御装置１０ａと同様に、通常運転モード及び保守運転モードの少なくとも２つの運転モードを含む複数の運転モードを切り替えながら、現在選択されている運転モードに従って下かご１ｂの運転を制御する。通常運転モード中において、エレベーターの保守員により下かご用保守運転選択部２０ｂが操作されて保守運転モードが選択されると、下かご制御装置１０ｂは下かご１ｂの運転モードを、通常運転モードから保守運転モードへと切り替える。 Similarly to the upper car control device 10a, the lower car control device 10b switches between a plurality of operation modes including at least two operation modes of a normal operation mode and a maintenance operation mode, and the lower car 1b according to the currently selected operation mode. To control the operation. In the normal operation mode, when the maintenance operation selection unit 20b for the lower car is operated by the elevator maintenance personnel to select the maintenance operation mode, the lower car control device 10b changes the operation mode of the lower car 1b from the normal operation mode. Switch to maintenance operation mode.
　下かご１ｂの保守運転モードにおいては、保守運転において下かご１ｂが走行可能な階床の範囲である保守運転範囲が設定される。この下かご１ｂの保守運転範囲を設定するために下かご用保守運転範囲設定部２１ｂが備えられている。この下かご用保守運転範囲設定部２１ｂは、下かご用保守運転範囲記憶部２２ｂ及び下かご用設定モード選択部２３ｂを備えている。 In the maintenance operation mode of the lower car 1b, a maintenance operation range that is a floor range in which the lower car 1b can travel in the maintenance operation is set. In order to set the maintenance operation range of the lower car 1b, a lower car maintenance operation range setting unit 21b is provided. The lower car maintenance operation range setting unit 21b includes a lower car maintenance operation range storage unit 22b and a lower car setting mode selection unit 23b.
　下かご用保守運転範囲記憶部２２ｂには、下かご１ｂの保守スケジュールとともに、それぞれの保守スケジュールにおける下かご１ｂの保守運転範囲が予め記憶されている。下かご用設定モード選択部２３ｂは、下かご１ｂの保守運転範囲の設定モードを自動設定モードと手動設定モードとから選択するためのものである。 In the lower car maintenance operation range storage unit 22b, the maintenance operation range of the lower car 1b in each maintenance schedule is stored in advance together with the maintenance schedule of the lower car 1b. The lower car setting mode selection unit 23b is for selecting a maintenance operation range setting mode of the lower car 1b from an automatic setting mode and a manual setting mode.
　保守運転範囲の設定モードが手動設定モードである場合に保守員が所望の保守運転範囲を入力するために、下かご用保守運転範囲入力部２４ｂが備えられている。下かご用保守運転選択部２０ｂにより保守運転モードが選択され、かつ、下かご用設定モード選択部２３ｂにより手動設定モードが選択されている場合には、乗場呼びボタンの操作信号は、下かご用保守運転範囲入力部２４ｂへと入力される。そして、下かご用保守運転範囲入力部２４ｂは、入力された乗場呼びボタンの操作信号を、下かご１ｂの保守運転範囲の指定として解釈する。 When the maintenance operation range setting mode is the manual setting mode, a maintenance operation range input unit 24b for the lower car is provided for a maintenance person to input a desired maintenance operation range. When the maintenance operation mode is selected by the lower car maintenance operation selection unit 20b and the manual setting mode is selected by the lower car setting mode selection unit 23b, the operation signal of the landing call button is for the lower car. It is input to the maintenance operation range input unit 24b. Then, the lower car maintenance operation range input unit 24b interprets the input operation signal of the hall call button as designation of the maintenance operation range of the lower car 1b.
　こうして、保守運転モード時に保守運転範囲の手動設定モードが選択されている場合には、保守員が乗場呼びボタンを操作することにより、手動で保守運転範囲を設定することができる。なお、ここでは、保守運転範囲の手動設定に乗場呼びボタンを利用する例について説明したが、かご内の行先階ボタンを利用するようにしてもよいし、制御盤内等に保守運転範囲設定用の専用ボタンを設けるようにしてもよい。 Thus, when the maintenance operation range manual setting mode is selected in the maintenance operation mode, the maintenance operator can manually set the maintenance operation range by operating the hall call button. In this example, the landing call button is used for manual setting of the maintenance operation range. However, the destination floor button in the car may be used, or the maintenance operation range may be set in the control panel. A dedicated button may be provided.
　下かご用保守運転選択部２０ｂにより下かご１ｂの運転モードとして保守運転モードが選択されると、下かご用保守運転範囲設定部２１ｂは、当該保守運転モードにおける下かご１ｂの保守運転範囲を設定する。 When the maintenance operation mode is selected as the operation mode of the lower car 1b by the lower car maintenance operation selection unit 20b, the lower car maintenance operation range setting unit 21b sets the maintenance operation range of the lower car 1b in the maintenance operation mode. To do.
　この際、保守運転範囲の設定モードが自動設定モードであれば、下かご用保守運転範囲設定部２１ｂは、下かご用保守運転範囲記憶部２２ｂに記憶されている情報に基づいて、下かご１ｂの保守運転範囲を自動的に設定する。また、保守運転範囲の設定モードが手動設定モードであれば、下かご用保守運転範囲設定部２１ｂは、下かご用保守運転範囲入力部２４ｂに入力されたボタン操作信号等により指定されたものに、下かご１ｂの保守運転範囲を設定する。 At this time, if the setting mode of the maintenance operation range is the automatic setting mode, the maintenance operation range setting unit 21b for the lower car is based on the information stored in the maintenance operation range storage unit 22b for the lower car. The maintenance operation range is automatically set. If the maintenance operation range setting mode is the manual setting mode, the lower car maintenance operation range setting unit 21b is designated by a button operation signal or the like input to the lower car maintenance operation range input unit 24b. The maintenance operation range of the lower car 1b is set.
　下かご制御装置１０ｂは、こうして下かご用保守運転範囲設定部２１ｂにより設定された保守運転範囲に従って下かご１ｂの保守運転を制御する。 The lower car control device 10b controls the maintenance operation of the lower car 1b according to the maintenance operation range thus set by the lower car maintenance operation range setting unit 21b.
　下かご制御装置１０ｂは、下かご用保守運転範囲設定部２１ｂにより設定された下かご１ｂの保守運転範囲に関する情報を、上かご制御装置１０ａへと送信する。上かご制御装置１０ａは、下かご制御装置１０ｂから送信された情報に基づいて、上かご位置検出部１２ａにより検出された上かご１ａの位置が、下かご１ｂの保守運転範囲内に入っているか否かを判定する。上かご１ａの位置が下かご１ｂの保守運転範囲内に入っている場合には、上かご制御装置１０ａは、上かご１ａが下かご１ｂの保守運転範囲内にある旨を下かご制御装置１０ｂへと送信する。 The lower car control device 10b transmits information related to the maintenance operation range of the lower car 1b set by the lower car maintenance operation range setting unit 21b to the upper car control device 10a. Whether the position of the upper car 1a detected by the upper car position detector 12a is within the maintenance operation range of the lower car 1b based on the information transmitted from the lower car control device 10b. Determine whether or not. When the position of the upper car 1a is within the maintenance operation range of the lower car 1b, the upper car control device 10a indicates that the upper car 1a is within the maintenance operation range of the lower car 1b. Send to.
　上かご制御装置１０ａから上かご１ａが下かご１ｂの保守運転範囲内にある旨を下かご制御装置１０ｂが受け取ると、下かご駆動部１１ｂは、下かご１ｂの走行を阻止する。また、下かご用報知部２５ｂにより、下かご１ｂの保守運転操作を行っている保守員に対して、上かご１ａが下かご１ｂの保守運転範囲内にある旨を報知する。この下かご用報知部２５ｂは、例えば、スピーカー等を用いてブザー音及び／又は音声を鳴動するようにしてもよいし、ディスプレイ等の表示装置にメッセージ等を表示したり、ランプを点灯等したりするようにしてもよい。また、これらの報知方法を併用するようにしてもよい。 When the lower car control device 10b receives from the upper car control device 10a that the upper car 1a is within the maintenance operation range of the lower car 1b, the lower car driving unit 11b prevents the lower car 1b from traveling. In addition, the lower car notifying unit 25b notifies the maintenance personnel performing the maintenance operation of the lower car 1b that the upper car 1a is within the maintenance operation range of the lower car 1b. The lower car notifying unit 25b may be configured to generate a buzzer sound and / or sound using a speaker or the like, or display a message or the like on a display device such as a display, or turn on a lamp. You may make it do. Moreover, you may make it use these notification methods together.
　このようにして、上かご１ａの位置が下かご１ｂの保守運転範囲内に入っている場合には、下かご１ｂの走行は阻止される。また、上かご制御装置１０ａにより上かご１ａの位置が下かご１ｂの保守運転範囲内に入っていると判定された場合、上かご駆動部１１ａは、上かご１ａ内に乗客がいない状態になり次第、上かご１ａを下かご１ｂの保守運転範囲外へと走行させる。上かご１ａ内に乗客がいない状態になったか否かは、上かご１ａの行先階の登録状況、秤装置の検出結果及び／又はカメラ装置により撮影された画像に基づいて判断することができる。 Thus, when the position of the upper car 1a is within the maintenance operation range of the lower car 1b, the traveling of the lower car 1b is blocked. When the upper car control device 10a determines that the position of the upper car 1a is within the maintenance operation range of the lower car 1b, the upper car driving unit 11a is in a state where there are no passengers in the upper car 1a. As a result, the upper car 1a is moved out of the maintenance operation range of the lower car 1b. Whether or not there is no passenger in the upper car 1a can be determined based on the registration status of the destination floor of the upper car 1a, the detection result of the scale device and / or the image taken by the camera device.
　上かご１ａが下かご１ｂの保守運転範囲外へと出ると、下かご駆動部１１ｂによる下かご１ｂの走行阻止が解除される。 When the upper car 1a goes out of the maintenance operation range of the lower car 1b, the travel prevention of the lower car 1b by the lower car driving unit 11b is released.
　なお、下かご用保守運転範囲設定部２１ｂは、下かご１ｂの保守運転範囲を設定する際に、下かご用保守運転範囲記憶部２２ｂに記憶されている保守運転範囲や下かご用保守運転範囲入力部２４ｂにより入力された保守運転範囲にかかわらず、自動的に下かご１ｂの現在位置から下端階までの範囲を保守運転範囲に含むように設定してもよい。言い換えれば、下かご用保守運転範囲設定部２１ｂは、下かご１ｂの保守運転範囲の下端を常に下端階に設定する。 The lower car maintenance operation range setting unit 21b sets the maintenance operation range and the lower car maintenance operation range stored in the lower car maintenance operation range storage unit 22b when setting the maintenance operation range of the lower car 1b. Regardless of the maintenance operation range input by the input unit 24b, a range from the current position of the lower car 1b to the lower floor may be automatically included in the maintenance operation range. In other words, the maintenance operation range setting unit 21b for the lower car always sets the lower end of the maintenance operation range of the lower car 1b to the lower floor.
　図３のフロー図は、この実施の形態におけるエレベーターの制御装置の保守運転時の動作を示すものである。
　なお、以下においては、上かご制御装置１０ａと下かご制御装置１０ｂとを区別せずにかご制御装置といい、上かご駆動部１１ａと下かご駆動部１１ｂとを区別せずにかご駆動部といい、上かご位置検出部１２ａと下かご位置検出部１２ｂとを区別せずにかご位置検出部という。 The flowchart of FIG. 3 shows the operation at the time of maintenance operation of the elevator control device in this embodiment.
In the following description, the upper car control device 10a and the lower car control device 10b are referred to as a car control device without being distinguished, and the upper car drive unit 11a and the lower car drive unit 11b are not distinguished from each other. The upper car position detector 12a and the lower car position detector 12b are referred to as car position detectors without being distinguished.
　また、上かご用保守運転選択部２０ａ、下かご用保守運転選択部２０ｂ、上かご用保守運転範囲設定部２１ａ、下かご用保守運転範囲設定部２１ｂ、上かご用保守運転範囲記憶部２２ａ、下かご用保守運転範囲記憶部２２ｂ、上かご用設定モード選択部２３ａ、下かご用設定モード選択部２３ｂ、上かご用保守運転範囲入力部２４ａ、下かご用保守運転範囲入力部２４ｂ、上かご用報知部２５ａ及び下かご用報知部２５ｂについても「上かご用」又は「下かご用」の部分を略し、上かご用と下かご用の区別せずに呼称する。 Also, an upper car maintenance operation selection unit 20a, a lower car maintenance operation selection unit 20b, an upper car maintenance operation range setting unit 21a, a lower car maintenance operation range setting unit 21b, an upper car maintenance operation range storage unit 22a, Lower car maintenance operation range storage unit 22b, upper car setting mode selection unit 23a, lower car setting mode selection unit 23b, upper car maintenance operation range input unit 24a, lower car maintenance operation range input unit 24b, upper car The notification part 25a and the notification part 25b for the lower car are also abbreviated as “for upper car” or “for lower car” and are called without distinction between the upper car and the lower car.
　まず、ステップＳ１において、かご制御装置は、保守運転選択部により保守運転モードが選択された否かを確認する。保守運転選択部により保守運転モードが選択されていない場合には、保守運転モードには移行せずに通常運転モードを継続する。一方、保守運転選択部により保守運転モードが選択された場合には、ステップＳ２へと移行する。 First, in step S1, the car control device confirms whether or not the maintenance operation mode is selected by the maintenance operation selection unit. When the maintenance operation mode is not selected by the maintenance operation selection unit, the normal operation mode is continued without shifting to the maintenance operation mode. On the other hand, when the maintenance operation mode is selected by the maintenance operation selection unit, the process proceeds to step S2.
　ステップＳ２においては、保守運転範囲設定部は、保守運転範囲の設定モードが自動設定モードであるか否かを確認する。保守運転範囲の設定モードが自動設定モードである場合には、ステップＳ３へと移行する。このステップＳ３においては、保守運転範囲設定部は、保守運転モードのかごの保守運転範囲を、保守運転範囲記憶部に予め記憶されている保守運転範囲に設定する。 In step S2, the maintenance operation range setting unit checks whether or not the maintenance operation range setting mode is the automatic setting mode. When the maintenance operation range setting mode is the automatic setting mode, the process proceeds to step S3. In this step S3, the maintenance operation range setting unit sets the maintenance operation range of the car in the maintenance operation mode to the maintenance operation range stored in advance in the maintenance operation range storage unit.
　一方、保守運転範囲の設定モードが自動設定モードである場合には、ステップＳ４へと移行する。このステップＳ４においては、保守運転範囲の設定モードは手動設定モードである。よって、保守運転範囲設定部は、保守運転モードのかごの保守運転範囲を、保守運転範囲入力部の情報に基づいて設定する。 On the other hand, when the setting mode of the maintenance operation range is the automatic setting mode, the process proceeds to step S4. In step S4, the maintenance operation range setting mode is the manual setting mode. Therefore, the maintenance operation range setting unit sets the maintenance operation range of the car in the maintenance operation mode based on the information of the maintenance operation range input unit.
　ステップＳ３又はステップＳ４の後は、ステップＳ５へと進む。このステップＳ５においては、かご制御装置は、保守運転モードのかごの保守運転範囲内に、通常運転モードで自動運転されている他のかごが進入することを禁止する。そして、続くステップＳ６において、かご制御装置は、保守運転モードのかごの保守運転範囲内に、通常運転モードで自動運転されている他のかごがあるか否かを確認する。 After step S3 or step S4, the process proceeds to step S5. In step S5, the car control device prohibits another car that is automatically operated in the normal operation mode from entering the maintenance operation range of the car in the maintenance operation mode. In subsequent step S6, the car control device checks whether there is another car that is automatically operated in the normal operation mode within the maintenance operation range of the car in the maintenance operation mode.
　保守運転モードのかごの保守運転範囲内に、通常運転モードで自動運転されている他のかごがある場合には、ステップＳ７へと進む。このステップＳ７においては、保守運転モードのかごの報知部のブザー鳴動等により保守員に、保守運転範囲内に他のかごがあることを知らせる。そして、ステップＳ８へと進み、保守運転モードのかごのかご駆動部は、保守運転モードのかごの起動を阻止する。 If there is another car that is automatically operated in the normal operation mode within the maintenance operation range of the car in the maintenance operation mode, the process proceeds to step S7. In step S7, the maintenance staff is informed that there is another car within the maintenance operation range by, for example, a buzzer sounding from the notification unit of the car in the maintenance operation mode. Then, the process proceeds to step S8, and the car drive unit in the maintenance operation mode prevents the car in the maintenance operation mode from being activated.
　ステップＳ８の後は、ステップＳ９へと進む。このステップＳ９においては、先のステップＳ６において保守運転モードのかごの保守運転範囲内にあることが確認された他のかご内に乗客がいないか否かを確認する。当該他のかご（自動運転かご）に乗客がいないことが確認された場合には、ステップＳ１０へと進む。 After step S8, the process proceeds to step S9. In this step S9, it is confirmed whether or not there are no passengers in the other cars that have been confirmed to be within the maintenance operation range of the car in the maintenance operation mode in the previous step S6. If it is confirmed that there are no passengers in the other car (automatic driving car), the process proceeds to step S10.
　一方、当該他のかご（自動運転かご）に乗客がいることが確認された場合には、当該他のかごに乗客がいないことが確認されるまで、次のステップには移行しない。なお、当該他のかご（自動運転かご）に乗客がいる場合に、当該他のかごにさらに新たな乗客が搭乗してしまうと、当該他のかごに乗客がいない状態となることが遅れ、当該他のかごを保守運転モードのかごの保守運転範囲外へと移動させることが遅れるため、ひいては、保守運転モードのかごが走行可能となるまでに必要な時間が長くなってしまう。 On the other hand, if it is confirmed that there are passengers in the other car (automatic driving car), the process does not proceed to the next step until it is confirmed that there are no passengers in the other car. If there are passengers in the other car (automated car) and there are new passengers in the other car, it will be delayed that there will be no passengers in the other car. Since it is delayed to move another car out of the maintenance operation range of the car in the maintenance operation mode, the time required until the car in the maintenance operation mode can run becomes longer.
　そこで、このような事態を防止するため、当該他のかご（自動運転かご）に乗客がいる間は、当該他のかごにさらに新たな乗客が搭乗することがないよう、当該他のかごを乗場呼びに応答させる等の新たな乗客が搭乗する可能性がある運転をさせないように制御するようにしてもよい。 Therefore, in order to prevent such a situation, while there are passengers in the other car (automated driving car), the other car is placed so that no new passengers can get on the other car. You may make it control so that the driving | operation which a new passenger may board, such as making it answer a call, is not made.
　ステップＳ１０においては、当該他のかご（自動運転かご）のかご駆動部は、先のステップＳ９で乗客がいないことが確認された当該他のかご（自動運転かご）を保守運転モードのかごの保守運転範囲外へと走行させる。そして、ステップＳ１１へと進み、保守運転モードのかごの報知部はブザー鳴動を解除し、続くステップＳ１２において、保守運転モードのかごのかご駆動部は、当該かごの起動阻止を解除する。 In step S10, the car driving unit of the other car (automatic operation car) maintains the other car (automatic operation car) that has been confirmed to have no passengers in step S9 as a maintenance operation mode car. Drive outside the driving range. Then, the process proceeds to step S11, in which the car notification unit in the maintenance operation mode releases the buzzer, and in the subsequent step S12, the car drive unit in the maintenance operation mode releases the start prevention of the car.
　こうして、ステップＳ１２を経た後は、保守運転モードのかごを保守運転範囲内において保守運転することができる。また、ステップ６において、保守運転モードのかごの保守運転範囲内に、通常運転モードで自動運転されている他のかごがなかった場合も、保守運転モードのかごを保守運転範囲内において保守運転することができる。 Thus, after passing through step S12, the car in the maintenance operation mode can be maintenance-operated within the maintenance operation range. Further, in step 6, even if there is no other car that is automatically operated in the normal operation mode within the maintenance operation range of the car in the maintenance operation mode, the maintenance operation of the car in the maintenance operation mode is performed within the maintenance operation range. be able to.
　保守運転範囲が設定されている間は、保守運転モードでない他のかごは、当該保守運転範囲内に進入することが禁止される。したがって、保守運転モードでない他のかごについては、当該保守運転範囲内の階床を行先階とする行先階呼びの登録が禁止される。 While the maintenance operation range is set, other cars that are not in the maintenance operation mode are prohibited from entering the maintenance operation range. Therefore, for other cars that are not in the maintenance operation mode, registration of a destination floor call with a floor in the maintenance operation range as a destination floor is prohibited.
　ステップＳ１２の後、又は、ステップＳ６で保守運転モードのかごの保守運転範囲内に、通常運転モードで自動運転されている他のかごがなかった場合には、ステップＳ１３へと移行する。このステップＳ１３においては、かご制御装置は、保守運転選択部により保守運転モードが解除された否かを確認する。保守運転モードが解除されていない場合には、保守運転モードを継続する。 After step S12 or when there is no other car that is automatically operated in the normal operation mode within the maintenance operation range of the car in the maintenance operation mode in step S6, the process proceeds to step S13. In step S13, the car control device confirms whether or not the maintenance operation mode is canceled by the maintenance operation selection unit. If the maintenance operation mode is not released, the maintenance operation mode is continued.
