Abstract

An elevator car (5) is provided with a door (21) and a motor (22). If the door (21) is closed, the motor (22) applies force to the door (21) in the closing direction. If a confinement detection unit (42) detects confinement when a photoelectric sensor (34) is detecting a plate (35), a transmission unit (51) transmits a first signal to an information center (4) where an operator (3) is present. If a second signal is received from the information center (4) as a response to the first signal, a cutoff unit (45) cuts off the supply of power to the motor (22) and releases the abovementioned force.

When the hoisting machine 9 is installed in the hoistway 7 , the hoisting machine 9 may be installed at the top of the hoistway 7 or may be installed in the pit of the hoistway 7 .
　かご５と制御装置１４とは、制御ケーブル１７によって接続される。かご５に備えられた機器は、制御装置１４によって制御される。かご５は、ドア２１、モータ２２、秤装置２３、カメラ２４、及び操作盤２５を備える。 The car 5 and the control device 14 are connected by a control cable 17. Equipment provided in the car 5 is controlled by the control device 14 . The car 5 has a door 21 , a motor 22 , a scale device 23 , a camera 24 and an operation panel 25 .
　かご５の出入口は、ドア２１によって開閉される。モータ２２は、ドア２１を駆動するための駆動力を発生させる。ドア２１が閉じていれば、モータ２２は、ドア２１に対して閉じる方向に力を与える。秤装置２３は、かご５の積載荷重を測定する。図１は、秤装置２３がかご５の下部に設けられる例を示す。秤装置２３は、ロープ８の端部に設けられても良い。 The doorway of the car 5 is opened and closed by the door 21. Motor 22 generates driving force for driving door 21 . If the door 21 is closed, the motor 22 applies force to the door 21 in the closing direction. A weighing device 23 measures the loaded load of the car 5 . FIG. 1 shows an example in which the weighing device 23 is provided below the car 5 . A weighing device 23 may be provided at the end of the rope 8 .
　操作盤２５は、表示器２６、インターホン２７、スピーカ２８、及び釦２９を備える。インターホン２７は、かご５内の乗客が情報センター４にいるオペレータ３と通話するための装置である。かご５内の乗客がインターホン２７によってオペレータ３と話をするための回線は、監視装置１５を介して情報センター４に接続される回線とは別の回線でも良い。釦２９には、かご呼びを登録するための行先釦、ドア２１を開くための開釦、及びドア２１を閉じるための閉釦が含まれる。釦２９に他の釦が含まれても良い。 The operation panel 25 includes a display 26, an intercom 27, a speaker 28, and a button 29. The intercom 27 is a device for the passengers in the car 5 to communicate with the operator 3 in the information center 4 . The line for passengers in the car 5 to talk with the operator 3 via the intercom 27 may be a line other than the line connected to the information center 4 via the monitoring device 15 . Buttons 29 include a destination button for registering a car call, an open button for opening door 21 and a close button for closing door 21 . Other buttons may be included in button 29 .
　かご５が停止する各乗場３１に、ドア３２が設けられる。乗場３１の出入口は、ドア３２によって開閉される。また、各乗場３１に、スイッチ３３が設けられる。スイッチ３３は、ドア３２が全閉していればオンになる。スイッチ３３は、ドア３２が開いていればオフになる。スイッチ３３は、ドア３２が開いていることを検出する検出器の一例である。 A door 32 is provided at each landing 31 where the car 5 stops. The entrance/exit of the landing 31 is opened and closed by a door 32 . A switch 33 is provided at each landing 31 . The switch 33 is turned on when the door 32 is fully closed. Switch 33 is turned off if door 32 is open. Switch 33 is an example of a detector that detects that door 32 is open.
　各乗場３１に、ドア３２を駆動するための装置は設けられていない。例えば、かご５がある乗場３１に停止すると、ドア２１は、その乗場３１のドア３２に対向する。ドア２１とドア３２とには、互いに対向した際にドア２１の動きをドア３２に伝えるための装置が設けられる。かご５が乗場３１に停止していれば、ドア３２はドア２１に連動する。このため、かご５が乗場３１に停止していれば、ドア３２は、ドア２１を介してモータ２２によって駆動される。 Each landing 31 is not provided with a device for driving the door 32 . For example, when the car 5 stops at a landing 31 , the door 21 faces the door 32 of the landing 31 . The door 21 and the door 32 are provided with a device for transmitting the movement of the door 21 to the door 32 when facing each other. If the car 5 is stopped at the landing 31, the door 32 is interlocked with the door 21. - 特許庁Therefore, if the car 5 is stopped at the landing 31 , the door 32 is driven by the motor 22 through the door 21 .
　エレベーター装置１は、かご５が特定の着床ゾーンＺに配置されていることを検出するための着床装置を備える。着床ゾーンＺは、各乗場３１の高さに合わせて予め設定される。以下においては、必要に応じて、Ｎ階の乗場３１の高さに合わせて設定された着床ゾーンを着床ゾーンＺＮと表記する。例えば、１階の乗場３１の高さに合わせて設定された着床ゾーンは、着床ゾーンＺ１である。着床ゾーンＺＮには、かご５がＮ階の乗場３１に停止する位置（停止位置）が含まれる。Ｎ階の乗場３１の停止位置とは、Ｎ階の乗場３１の床面とかご５の床面との高さが同じになるかご５の位置である。 The elevator device 1 includes a landing device for detecting that the car 5 is placed in a specific landing zone Z. The landing zone Z is preset according to the height of each landing 31 . Hereinafter, the landing zone set in accordance with the height of the landing 31 on the Nth floor will be referred to as a landing zone ZN as required. For example, the landing zone set according to the height of the landing 31 on the first floor is the landing zone Z1. The landing zone ZN includes a position (stop position) where the car 5 stops at the landing 31 of the Nth floor. The stop position of the N floor landing 31 is the position of the car 5 at which the height of the floor of the N floor landing 31 and the floor of the car 5 are the same.
　一例として、着床装置は、光電センサ３４、及びプレート３５を備える。光電センサ３４は、かご５に設けられる。プレート３５は、昇降路７に設けられる。プレート３５は、各乗場３１の停止位置に合わせて配置される。例えば、Ｎ階の乗場３１の高さに合わせて配置されたプレート３５を光電センサ３４が検出できる範囲が、着床ゾーンＺＮである。光電センサ３４がプレート３５を検出すると、光電センサ３４から制御装置１４に、検出されたプレート３５に対応する検出信号が送信される。かご５が着床ゾーンＺＮに配置されていれば、Ｎ階の乗場３１のドア３２はドア２１に連動する。 As an example, the landing device includes a photoelectric sensor 34 and a plate 35. A photoelectric sensor 34 is provided on the car 5 . A plate 35 is provided in the hoistway 7 . The plate 35 is arranged according to the stop position of each landing 31 . For example, the landing zone ZN is a range in which the photoelectric sensor 34 can detect the plate 35 arranged according to the height of the landing 31 on the Nth floor. When the photoelectric sensor 34 detects the plate 35 , a detection signal corresponding to the detected plate 35 is transmitted from the photoelectric sensor 34 to the control device 14 . If the car 5 is arranged in the landing zone ZN, the door 32 of the landing 31 on the N floor is interlocked with the door 21 .
　プレート３５は、乗場３１の停止位置に合わせて配置された被検出体の一例である。光電センサ３４は、当該被検出体を検出するセンサの一例である。エレベーター装置１に、上記方法とは異なる方法によってかご５が着床ゾーンに配置されていることを検出するための装置が備えられても良い。 The plate 35 is an example of an object to be detected arranged in accordance with the stop position of the landing 31 . The photoelectric sensor 34 is an example of a sensor that detects the object to be detected. The elevator system 1 may be provided with a device for detecting that the car 5 is placed in the landing zone by a method different from the method described above.
　図２は、制御装置１４及び監視装置１５の機能を説明するための図である。図２に示すように、制御装置１４は、運転制御部４１、閉じ込め検出部４２、処理実行部４３、報知制御部４４、遮断部４５、及び乗客検出部４６を備える。監視装置１５は、送信部５１、及び要求部５２を備える。 FIG. 2 is a diagram for explaining the functions of the control device 14 and the monitoring device 15. FIG. As shown in FIG. 2 , the control device 14 includes an operation control section 41 , a confinement detection section 42 , a process execution section 43 , a notification control section 44 , a blocking section 45 and a passenger detection section 46 . The monitoring device 15 includes a transmitter 51 and a requester 52 .
　以下に、図３から図６も参照し、本エレベーターシステムの動作について詳しく説明する。図３は、制御装置１４の動作例を示すフローチャートである。 The operation of this elevator system will be described in detail below with reference to FIGS. 3 to 6 as well. FIG. 3 is a flow chart showing an operation example of the control device 14 .
　エレベーターの通常運転では、制御装置１４は、登録された呼びにかご５を順次応答させる。例えば、１階の乗場３１で釦（図示せず）が押されると、乗場呼びが登録される。運転制御部４１は、かご５を１階の乗場３１に停止させ、ドア２１を開く。上述したように、かご５が着床ゾーンＺ１に停止していれば、ドア２１とともに１階のドア３２が開く。これにより、乗客は、乗場３１からかご５に乗ることができる。 　In normal operation of the elevator, the control device 14 causes the car 5 to respond to registered calls in sequence. For example, when a button (not shown) is pressed at the hall 31 on the first floor, a hall call is registered. The operation control unit 41 stops the car 5 at the landing 31 on the first floor and opens the door 21 . As described above, if the car 5 is stopped at the landing zone Z1, the door 21 and the door 32 of the first floor are opened. This allows passengers to get on the car 5 from the landing 31 .
　制御装置１４では、かご呼びが登録されたか否かが判定される（Ｓ１０１）。かご５の釦２９が押されると、かご呼びが登録される（Ｓ１０１のＹｅｓ）。例えば、乗客は、かご５内で５階の行先釦を押す。これにより、運転制御部４１は、登録されたかご呼びにかご５を応答させる（Ｓ１０２）。即ち、運転制御部４１は、かご５を５階の乗場３１に向けて移動させる。 The control device 14 determines whether or not a car call has been registered (S101). When the button 29 for car 5 is pressed, a car call is registered (Yes in S101). For example, the passenger presses the destination button for floor 5 in car 5 . As a result, the operation control unit 41 causes the car 5 to respond to the registered car call (S102). That is, the operation control unit 41 moves the car 5 toward the landing 31 on the fifth floor.
　制御装置１４では、かご５が５階の乗場３１の停止位置に配置されたか否かが判定される（Ｓ１０３）。かご５が５階の乗場３１の停止位置に接近すると、５階の乗場３１の高さに合わせて配置されたプレート３５が光電センサ３４によって検出される。運転制御部４１は、光電センサ３４の検出結果に基づいて、かご５が５階の乗場３１の停止位置に配置されたことを判定する（Ｓ１０３のＹｅｓ）。Ｓ１０３でＹｅｓと判定すると、運転制御部４１は、かご５を停止させる（Ｓ１０４）。 The control device 14 determines whether or not the car 5 is placed at the stop position of the hall 31 on the fifth floor (S103). When the car 5 approaches the stop position of the fifth-floor landing 31 , the photoelectric sensor 34 detects the plate 35 arranged in accordance with the height of the fifth-floor landing 31 . Based on the detection result of the photoelectric sensor 34, the operation control unit 41 determines that the car 5 has been placed at the stop position of the hall 31 on the fifth floor (Yes in S103). When it is determined as Yes in S103, the operation control unit 41 stops the car 5 (S104).
　また、制御装置１４では、かご５に乗客が閉じ込められたか否かが判定される（Ｓ１０２）。かご５に乗客が閉じ込められたことは、閉じ込め検出部４２によって検出される。閉じ込め検出部４２は、秤装置２３が測定した積載荷重を利用して乗客の閉じ込めを検出しても良い。閉じ込め検出部４２は、カメラ２４が撮影した画像を利用して乗客の閉じ込めを検出しても良い。 Also, the control device 14 determines whether or not a passenger is trapped in the car 5 (S102). The confinement detector 42 detects that the passenger is confined in the car 5 . The confinement detection unit 42 may detect the confinement of the passenger using the load measured by the weighing device 23 . The confinement detection unit 42 may detect the confinement of the passenger using the image captured by the camera 24 .
　他の例として、登録されたかご呼びに応答してかご５がＳ１０４で乗場３１に停止した場合、閉じ込め検出部４２は、一定時間が経過してもその階のドア３２が開いていることをスイッチ３３が検出しない場合に閉じ込めを検出しても良い。Ｓ１０４でかご５が５階の乗場３１に停止した後、一定時間が経過する前に５階のドア３２が開いていることをスイッチ３３が検出すると、Ｓ１０５でＮｏと判定される。かかる場合、通常運転が継続される。 As another example, when the car 5 stops at the hall 31 in S104 in response to a registered car call, the confinement detection unit 42 detects that the door 32 of that floor is open even after a certain period of time has passed. Confinement may be detected when switch 33 does not. If the switch 33 detects that the door 32 on the fifth floor is open before a certain period of time elapses after the car 5 has stopped at the hall 31 on the fifth floor in S104, the determination is No in S105. In such a case, normal operation is continued.
　Ｓ１０４でかご５が５階の乗場３１に停止した後、一定時間が経過しても５階のドア３２が開いていることをスイッチ３３が検出しなければ、閉じ込め検出部４２は閉じ込めを検出する（Ｓ１０５のＹｅｓ）。例えば、かご５に、ドア２１を制御するための基板が設けられる。当該基板が故障すると、Ｓ１０５でＹｅｓと判定される。他の例として、特定の階への停止を禁止するスイッチをかご５内で乗客が誤って操作してしまうと、Ｓ１０５でＹｅｓと判定される。 If the switch 33 does not detect that the door 32 on the 5th floor is open even after a certain period of time has elapsed after the car 5 has stopped at the hall 31 on the 5th floor in S104, the confinement detector 42 detects confinement. (Yes in S105). For example, the car 5 is provided with a board for controlling the door 21 . If the board fails, the determination in S105 is Yes. As another example, if a passenger erroneously operates a switch in the car 5 that prohibits stopping at a specific floor, the determination in S105 is Yes.
　上記例のように、光電センサ３４がプレート３５を検出している時に閉じ込め検出部４２が閉じ込めを検出すると、Ｓ１０５でＹｅｓと判定される。Ｓ１０５でＹｅｓと判定されると、制御装置１４から監視装置１５に対して、発報要求が送信される（Ｓ１０６）。 As in the above example, if the confinement detection unit 42 detects confinement while the photoelectric sensor 34 is detecting the plate 35, S105 is determined to be Yes. If it is determined as Yes in S105, the control device 14 transmits an alarm request to the monitoring device 15 (S106).
　図４は、監視装置１５の動作例を示すフローチャートである。監視装置１５では、制御装置１４から発報要求を受信したか否かが判定される（Ｓ２０１）。Ｓ１０６で制御装置１４から送信された発報要求を監視装置１５が受信すると、Ｓ２０１でＹｅｓと判定される。Ｓ２０１でＹｅｓと判定される、即ちＳ１０５でＹｅｓと判定されると、送信部５１は、情報センター４に対して特定の第１信号を送信する（Ｓ２０２）。 FIG. 4 is a flowchart showing an operation example of the monitoring device 15. FIG. In the monitoring device 15, it is determined whether or not an alarm request has been received from the control device 14 (S201). When the monitoring device 15 receives the alarm request transmitted from the control device 14 in S106, it is determined as Yes in S201. If determined as Yes in S201, that is, determined as Yes in S105, the transmitting unit 51 transmits a specific first signal to the information center 4 (S202).
　図５は、情報センター４の機能を説明するための図である。情報センター４は、通話装置６１、表示器６２、入力装置６３、及び制御装置６４を備える。 FIG. 5 is a diagram for explaining the functions of the information center 4. FIG. The information center 4 includes a communication device 61 , a display device 62 , an input device 63 and a control device 64 .
　通話装置６１は、情報センター４にいるオペレータ３がかご５内にいる乗客と通話するための装置である。オペレータ３は、通話装置６１でかご５内にいる乗客と話をし、表示器６２を見ながら入力装置６３を操作する。一例として、入力装置６３は、キーボード及びマウスを備える。入力装置６３として、他の装置が備えられても良い。 The communication device 61 is a device for the operator 3 in the information center 4 to communicate with the passengers in the car 5. The operator 3 talks with passengers in the car 5 using the communication device 61 and operates the input device 63 while looking at the display 62 . As an example, the input device 63 comprises a keyboard and mouse. Other devices may be provided as the input device 63 .
　図５に示す例では、表示器６２に、画像Ａ、画像Ｂ、モード選択欄Ｃ、確認事項欄Ｄ、及び実行釦Ｅが表示される。 In the example shown in FIG. 5, the display 62 displays an image A, an image B, a mode selection column C, a confirmation item column D, and an execution button E.
　画像Ａは、カメラ２４によって撮影された画像である。オペレータ３は、画像Ａを見ることにより、かご５内の様子を知ることができる。画像Ｂは、表示器２６に表示されている画像である。オペレータ３は、画像Ｂを見ることにより、かご５内の乗客が見ている画像を知ることができる。 An image A is an image captured by the camera 24. By viewing the image A, the operator 3 can know the state inside the car 5 . Image B is an image displayed on display 26 . By viewing the image B, the operator 3 can know the image viewed by the passengers in the car 5 .
　モード選択欄Ｃには、選択可能な救出運転モードが表示される。オペレータ３は、入力装置６３を操作することにより、救出運転モードの１つを選択することができる。確認事項欄Ｄには、選択された救出運転モードを実行する際にオペレータ３が確認すべき事項が表示される。実行釦Ｅは、選択された救出運転モードを実行するためにオペレータ３が押す釦である。 The mode selection column C displays selectable rescue operation modes. The operator 3 can select one of the rescue operation modes by operating the input device 63 . Items to be confirmed by the operator 3 are displayed in the confirmation item field D when the selected rescue operation mode is executed. The execution button E is a button that the operator 3 pushes to execute the selected rescue operation mode.
　図６は、制御装置６４の動作例を示すフローチャートである。制御装置６４では、エレベーター装置１から第１信号を受信したか否かが判定される（Ｓ３０１）。Ｓ２０２で監視装置１５から送信された第１信号を制御装置６４が受信すると、Ｓ３０１でＹｅｓと判定される。 FIG. 6 is a flowchart showing an operation example of the control device 64. FIG. In the control device 64, it is determined whether or not the first signal has been received from the elevator device 1 (S301). When the control device 64 receives the first signal transmitted from the monitoring device 15 in S202, a determination of Yes is made in S301.
　Ｓ３０１でＹｅｓと判定されると、制御装置６４では、選択可能な救出運転モードの１つに「戸閉力解除」が追加される（Ｓ３０２）。そして、制御装置６４では、「戸閉力解除」が選択されたか否かが判定される（Ｓ３０３）。オペレータ３は、モード選択欄Ｃに表示されたプルダウンを操作し、「戸閉力解除」を選択する。これにより、Ｓ３０３でＹｅｓと判定される。 When it is determined as Yes in S301, the controller 64 adds "door closing force release" to one of the selectable rescue operation modes (S302). Then, in the control device 64, it is determined whether or not "cancel door closing force" is selected (S303). The operator 3 operates the pull-down displayed in the mode selection field C and selects "cancel door closing force". As a result, a determination of Yes is made in S303.
　なお、制御装置６４がエレベーター装置１から当該第１信号を受信していなければ、モード選択欄Ｃに「戸閉力解除」は表示されない、或いは「戸閉力解除」は選択できない状態で表示される。モード選択欄Ｃにおいて、「戸閉力解除」は、制御装置６４が当該第１信号を受信することによって選択可能になる。 If the control device 64 does not receive the first signal from the elevator device 1, the "door closing force canceled" is not displayed in the mode selection field C, or the "door closing force canceled" is displayed in a state where it cannot be selected. be. In the mode selection column C, "door closing force release" becomes selectable when the control device 64 receives the first signal.
　Ｓ３０３でＹｅｓと判定されると、制御装置６４では、実行釦Ｅが押されたか否かが判定される（Ｓ３０４）。オペレータ３は、確認事項欄Ｄに表示された内容を読み、必要な動作を行った上で実行釦Ｅを押す（Ｓ３０４のＹｅｓ）。例えば、オペレータ３は、実行釦Ｅを押す前にかご５内の乗客に対して以下の事項を伝える。
・今からドアを手で開けられるようにすること。
・指示があるまで、通話を切らないこと。
・かごから降りる際に段差があるかも知れないこと。
・かごに乗ってくる人がいたら、降車を促すこと。 If it is determined as Yes in S303, the control device 64 determines whether or not the execution button E has been pressed (S304). The operator 3 reads the contents displayed in the confirmation item column D, performs necessary operations, and presses the execution button E (Yes in S304). For example, before pressing the execution button E, the operator 3 informs the passengers in the car 5 of the following items.
・From now on, you should be able to open the door by hand.
・Do not hang up until instructed to do so.
・There may be steps when getting off the car.
・If someone is riding in a car, encourage them to get off.
　Ｓ３０４でＹｅｓと判定されると、制御装置６４からエレベーター装置１に対し、第１信号の応答として第２信号が送信される（Ｓ３０５）。 When it is determined as Yes in S304, a second signal is transmitted from the control device 64 to the elevator device 1 as a response to the first signal (S305).
　図４に示すように、監視装置１５では、Ｓ２０２で第１信号を情報センター４に送信すると、その応答として情報センター４から第２信号を受信したか否かが判定される（Ｓ２０３）。Ｓ３０５で制御装置６４から送信された第２信号を監視装置１５が受信すると、Ｓ２０３でＹｅｓと判定される。例えば、Ｓ２０２で第１信号を送信した記録がなければ、制御装置６４から第２信号を受信したとしても、Ｓ２０３でＹｅｓと判定されない。一例として、制御装置６４から第２信号を受信しても、その第２信号を受信する直前の一定時間に送信部５１が第１信号を送信していなければ、Ｓ２０３でＹｅｓと判定されない。Ｓ２０３でＹｅｓと判定されると、要求部５２は、制御装置１４に対して救出要求を送信する（Ｓ２０４）。救出要求に、第２信号が含まれても良い。要求部５２は、受信した第２信号を救出要求として制御装置１４に転送しても良い。 As shown in FIG. 4, when the monitoring device 15 transmits the first signal to the information center 4 in S202, it is determined whether or not the second signal has been received from the information center 4 in response (S203). When the monitoring device 15 receives the second signal transmitted from the control device 64 in S305, a determination of Yes is made in S203. For example, if there is no record of transmitting the first signal in S202, even if the second signal is received from the control device 64, it will not be determined as Yes in S203. As an example, even if the second signal is received from the control device 64, if the transmitting unit 51 does not transmit the first signal for a certain period of time immediately before receiving the second signal, S203 is not determined to be Yes. If determined as Yes in S203, the request unit 52 transmits a rescue request to the control device 14 (S204). The rescue request may include the second signal. The request unit 52 may transfer the received second signal to the control device 14 as a rescue request.
　図３に示すように、制御装置１４では、Ｓ１０６で発報要求を監視装置１５に送信すると、監視装置１５から救出要求を受信したか否かが判定される（Ｓ１０７）。Ｓ２０４で要求部５２から送信された救出要求を制御装置１４が受信すると、Ｓ１０７でＹｅｓと判定される。Ｓ１０７でＹｅｓと判定される、即ち第１信号の応答としてエレベーター装置１が情報センター４から第２信号を受信すると、処理実行部４３は救出処理を開始する（Ｓ１０８）。 As shown in FIG. 3, when the control device 14 transmits the alarm request to the monitoring device 15 in S106, it is determined whether or not a rescue request has been received from the monitoring device 15 (S107). When the control device 14 receives the rescue request transmitted from the request unit 52 in S204, it is determined as Yes in S107. When it is determined as Yes in S107, that is, when the elevator apparatus 1 receives the second signal from the information center 4 in response to the first signal, the process executing section 43 starts the rescue process (S108).
　救出処理では、先ず、報知制御部４４が、スピーカ２８から乗客に対する音声案内を行う（Ｓ１０９）。一例として、報知制御部４４は、Ｓ１０９において、異常を感じたら外部に知らせる旨をスピーカ２８から報知する。報知制御部４４は、Ｓ１０９において、ドア２１から離れる旨をスピーカ２８から報知しても良い。報知制御部４４は、Ｓ１０９において、他の内容をスピーカ２８から報知しても良い。音声案内が終了した後、報知制御部４４は、スピーカ２８から警告音を発しても良い。 In the rescue process, first, the notification control unit 44 provides voice guidance to the passengers from the speaker 28 (S109). As an example, in S109, the notification control unit 44 notifies from the speaker 28 that an abnormality will be notified to the outside. In S109, the notification control unit 44 may notify through the speaker 28 that the user is leaving the door 21 . The notification control unit 44 may notify other contents from the speaker 28 in S109. After the voice guidance ends, the notification control unit 44 may issue a warning sound from the speaker 28 .
　Ｓ１０９の音声案内が終了すると、遮断部４５は、モータ２２への電力の供給を遮断する。例えば、遮断部４５は、モータ２２のインバータに対してベース遮断を行う（Ｓ１１０）。上述したように、モータ２２は、ドア２１が閉じていれば、ドア２１に対して閉じる方向に力を与える。以下においては、当該力を戸閉力ともいう。遮断部４５は、Ｓ１１０でベース遮断を行うことにより、当該戸閉力を消失させる。 When the voice guidance in S109 ends, the cutoff unit 45 cuts off the power supply to the motor 22. For example, the cutoff unit 45 cuts off the base of the inverter of the motor 22 (S110). As described above, the motor 22 applies force to the door 21 in the closing direction if the door 21 is closed. In the following, this force is also referred to as door closing force. The blocking unit 45 eliminates the door closing force by performing the base blocking in S110.
　Ｓ１１０でベース遮断が行われると、報知制御部４４は、スピーカ２８から乗客に対する音声案内を行う（Ｓ１１１）。一例として、報知制御部４４は、Ｓ１１１において、ドア２１が手で開けられるようになった旨をスピーカ２８から報知する。報知制御部４４は、Ｓ１１１において、他の内容をスピーカ２８から報知しても良い。 When the base is cut off in S110, the notification control unit 44 provides voice guidance to passengers from the speaker 28 (S111). As an example, the notification control unit 44 notifies from the speaker 28 that the door 21 can be opened by hand in S111. The notification control unit 44 may notify other contents from the speaker 28 in S111.
　Ｓ１１１で音声案内が行われると、制御装置１４では、かご５が無人であるか否かが判定される（Ｓ１１２）。乗客検出部４６は、かご５が無人であることを検出する。乗客検出部４６は、秤装置２３が測定した積載荷重に基づいて、かご５が無人であることを検出しても良い。乗客検出部４６は、カメラ２４が撮影した画像に基づいて、かご５が無人であることを検出しても良い。Ｓ１１１で音声案内が行われた後、かご５が無人であることを乗客検出部４６が検出すると、救出処理は終了する（Ｓ１１３）。 When the voice guidance is provided in S111, the control device 14 determines whether or not the car 5 is unmanned (S112). A passenger detection unit 46 detects that the car 5 is unmanned. The passenger detection unit 46 may detect that the car 5 is unmanned based on the load measured by the weighing device 23 . The passenger detection unit 46 may detect that the car 5 is unmanned based on the image captured by the camera 24 . After the voice guidance is provided in S111, when the passenger detection unit 46 detects that the car 5 is unmanned, the rescue process ends (S113).
　Ｓ１１３では、例えば、現場に到着した保守員による特定の手動操作が行われるまで、エレベーターの再起動が禁止される。Ｓ１１３では、救出処理が終了した旨の信号が情報センター４に送信されても良い。 In S113, for example, restarting the elevator is prohibited until a specific manual operation is performed by maintenance personnel who have arrived at the site. In S<b>113 , a signal indicating that the rescue process has ended may be sent to the information center 4 .
　本実施の形態に示す例であれば、エレベーター装置１においてドア２１用の基板等に故障が発生した場合でも、かご５に閉じ込められた乗客を容易に救出することができる。この時、遠隔にいるオペレータ３は、モータ２２への電力供給を遮断しても良いか否かの判断を自身の責任のみで行う必要はない。このため、オペレータ３の負担を軽減できる。また、遮断部４５は、第１信号の応答として第２信号を受信しなければ、モータ２２への電力供給を遮断しない。このため、適切な状況下において、ドア２１を手動で開くようにすることができる。 In the example shown in the present embodiment, even if the substrate for the door 21 or the like of the elevator device 1 fails, the passengers trapped in the car 5 can be easily rescued. At this time, the remote operator 3 does not have to decide whether or not to cut off the power supply to the motor 22 on his own responsibility. Therefore, the burden on the operator 3 can be reduced. Also, the cutoff unit 45 does not cut off the power supply to the motor 22 unless it receives the second signal in response to the first signal. Thus, under appropriate circumstances, the door 21 can be manually opened.
　本実施の形態では、乗場３１のドア３２が開いていることを検出するためのスイッチ３３を利用して、エレベーター装置１から情報センター４に第１信号を送信する例について説明した。他の例として、かご５に備えられたスイッチ３０を利用して、第１信号の送信を行っても良い。 In the present embodiment, an example has been described in which the first signal is transmitted from the elevator device 1 to the information center 4 using the switch 33 for detecting that the door 32 of the hall 31 is open. As another example, the switch 30 provided in the car 5 may be used to transmit the first signal.
　スイッチ３０は、ドア２１が全閉していればオンになる。スイッチ３０は、ドア２１が開いていればオフになる。スイッチ３０は、ドア２１が開いていることを検出する検出器の一例である。登録されたかご呼びに応答してかご５がＳ１０４で乗場３１に停止した場合、閉じ込め検出部４２は、一定時間が経過してもドア２１が開いていることをスイッチ３０が検出しない場合に閉じ込めを検出しても良い。Ｓ１０４でかご５が乗場３１に停止した後、一定時間が経過する前にドア２１が開いていることをスイッチ３０が検出すると、Ｓ１０５でＮｏと判定される。Ｓ１０５でＹｅｓと判定されると、制御装置１４から監視装置１５に対して、発報要求が送信される（Ｓ１０６）。 The switch 30 is turned on when the door 21 is fully closed. Switch 30 is turned off if door 21 is open. Switch 30 is an example of a detector that detects that door 21 is open. When the car 5 stops at the hall 31 in S104 in response to the registered car call, the lock detection unit 42 detects that the door 21 is open even after a certain period of time has elapsed. may be detected. If the switch 30 detects that the door 21 is open before a certain period of time elapses after the car 5 has stopped at the hall 31 in S104, the determination is No in S105. If it is determined as Yes in S105, the control device 14 transmits an alarm request to the monitoring device 15 (S106).
