FIG. 1 is a diagram showing an example of an elevator system according to the first embodiment. The elevator system shown in FIG. 1 includes a car 1 and a balance weight 2. The car 1 moves up and down in the hoistway 3. The balance weight 2 moves up and down on the hoistway 3. The car 1 and the balance weight 2 are suspended from the hoistway 3 by the main rope 4.
　主ロープ４は、巻上機５の駆動綱車６に巻き掛けられる。かご１は、駆動綱車６の回転に応じて移動する。制御装置７は、巻上機５を制御する。即ち、かご１の移動は、制御装置７によって制御される。 The main rope 4 is wound around the drive sheave 6 of the hoisting machine 5. The car 1 moves according to the rotation of the drive sheave 6. The control device 7 controls the hoisting machine 5. That is, the movement of the car 1 is controlled by the control device 7.
　監視装置８は、制御装置７に接続される。監視装置８は、制御装置７と通信する。監視装置８は、エレベーター装置が外部と通信を行うための装置である。例えば、監視装置８は、ネットワーク９を介して遠隔の監視センター１０に接続される。具体的に、監視装置８は、ネットワーク９を介して監視センター１０に備えられた外部機器１１と通信する。 The monitoring device 8 is connected to the control device 7. The monitoring device 8 communicates with the control device 7. The monitoring device 8 is a device for the elevator device to communicate with the outside. For example, the monitoring device 8 is connected to the remote monitoring center 10 via the network 9. Specifically, the monitoring device 8 communicates with the external device 11 provided in the monitoring center 10 via the network 9.
　監視装置８に、アクセスポイント１２が接続される。アクセスポイント１２は、特定の機器が監視装置８と無線通信を行う際に使用される。上記特定の機器には、例えば、保守用の携帯端末１３が含まれる。携帯端末１３は、エレベーターの保守員によって所有される。保守員は、携帯端末１３を使用してエレベーターの保守作業を行う。なお、監視装置８は、アクセスポイント１２を介することなく外部機器１１と通信することが可能である。 The access point 12 is connected to the monitoring device 8. The access point 12 is used when a specific device wirelessly communicates with the monitoring device 8. The specific device includes, for example, a mobile terminal 13 for maintenance. The mobile terminal 13 is owned by an elevator maintenance person. The maintenance staff uses the mobile terminal 13 to perform maintenance work on the elevator. The monitoring device 8 can communicate with the external device 11 without going through the access point 12.
　監視装置８に、地震計１４が接続される。地震計１４は、例えば建物の加速度を検出する。地震計１４によって検出された加速度のデータは、監視装置８に入力される。監視装置８は、地震計１４によって特定レベル以上の加速度が検出されると、地震管制運転を実施させるための信号を制御装置７に送信する。地震計１４は、制御装置７に接続されても良い。この場合、地震計１４によって検出された加速度のデータは、制御装置７に入力される。制御装置７は、地震計１４によって特定レベル以上の加速度が検出されると、地震管制運転を実施する。また、地震計１４は、特定レベル以上の加速度を検出した際に地震検知信号を出力しても良い。地震計１４が監視装置８に接続されていれば、地震計１４からの地震検知信号は監視装置８に入力される。監視装置８は、地震計１４から地震検知信号を受信すると、地震管制運転を実施させるための信号を制御装置７に送信する。地震計１４が制御装置７に接続されている場合、地震計１４からの地震検知信号は制御装置７に入力される。この場合、制御装置７は、地震計１４から地震検知信号を受信すると、地震管制運転を実施する。地震計１４は、昇降路３のピット３ａに設けられても良い。 The seismograph 14 is connected to the monitoring device 8. The seismograph 14 detects, for example, the acceleration of a building. The acceleration data detected by the seismograph 14 is input to the monitoring device 8. When the seismograph 14 detects an acceleration of a specific level or higher, the monitoring device 8 transmits a signal for executing the seismic control operation to the control device 7. The seismograph 14 may be connected to the control device 7. In this case, the acceleration data detected by the seismograph 14 is input to the control device 7. When the seismograph 14 detects an acceleration of a specific level or higher, the control device 7 performs seismic control operation. Further, the seismograph 14 may output an earthquake detection signal when an acceleration of a specific level or higher is detected. If the seismograph 14 is connected to the monitoring device 8, the earthquake detection signal from the seismograph 14 is input to the monitoring device 8. When the monitoring device 8 receives the earthquake detection signal from the seismograph 14, it transmits a signal for executing the seismic control operation to the control device 7. When the seismograph 14 is connected to the control device 7, the seismic detection signal from the seismograph 14 is input to the control device 7. In this case, when the control device 7 receives the earthquake detection signal from the seismograph 14, the control device 7 performs the seismic control operation. The seismograph 14 may be provided in the pit 3a of the hoistway 3.
　かご１と制御装置７との間に、制御ケーブル１５が接続される。制御ケーブル１５は、かご１から下方に延びる。かご１から下方に延びた制御ケーブル１５は、昇降路３の内部で方向転換されて上方に延びる。制御ケーブル１５は、かご１の移動を阻害することがないように、昇降路３の内部でＵ字状に吊り下げられる。 The control cable 15 is connected between the car 1 and the control device 7. The control cable 15 extends downward from the car 1. The control cable 15 extending downward from the car 1 is turned around inside the hoistway 3 and extends upward.

　制御装置３２の選択部４１は、光源を選択する。本実施の形態に示す例では、選択部４１は、光源として可視光ランプ２２又は赤外線ランプ２３を選択する。放射制御部４２は、選択部４１が選択した光源から電磁波を放射させる。即ち、放射制御部４２は、選択部４１が可視光ランプ２２を選択すると、可視光ランプ２２から可視光を放射させる。放射制御部４２は、選択部４１が赤外線ランプ２３を選択すると、赤外線ランプ２３から赤外線を放射させる。カメラユニット１６が赤外線ランプ２３を備えていなければ、制御装置３２は選択部４１を備える必要はない。 The selection unit 41 of the control device 32 selects a light source. In the example shown in this embodiment, the selection unit 41 selects the visible light lamp 22 or the infrared lamp 23 as the light source.

When the selection unit 41 selects the infrared lamp 23, the radiation control unit 42 emits infrared rays from the infrared lamp 23. If the camera unit 16 does not include the infrared lamp 23, the control device 32 does not need to include the selection unit 41.
　カメラユニット１７の形状及び機能は、カメラユニット１６の形状及び機能と同様である。なお、カメラユニット１７に備えられた可視光ランプ２２からは、上方に向けて可視光が放射される。カメラユニット１７に備えられた赤外線ランプ２３からは、上方に向けて赤外線が放射される。カメラユニット１７に備えられたカメラ２４は、かご１の上方が撮影できるように向きが設定される。カメラユニット１７の形状及び機能に関する他の説明は省略する。 The shape and function of the camera unit 17 are the same as the shape and function of the camera unit 16. Visible light is emitted upward from the visible light lamp 22 provided in the camera unit 17. Infrared rays are emitted upward from the infrared lamp 23 provided in the camera unit 17. The direction of the camera 24 provided in the camera unit 17 is set so that the upper part of the car 1 can be photographed. Other description of the shape and function of the camera unit 17 will be omitted.
　図４は、カメラユニット１６の基本動作の例を示すフローチャートである。エレベーターでは、通常、自動運転が行われる。自動運転は、登録された呼びにかご１を順次応答させる運転である。自動運転が行われている時に昇降路３の内部が光ると、利用者がその光を不審に感じる場合がある。このため、エレベーターで自動運転が行われていれば、選択部４１は、例えば光源として赤外線ランプ２３を選択する（Ｓ１０１）。 FIG. 4 is a flowchart showing an example of the basic operation of the camera unit 16. Elevators are usually self-driving. The automatic operation is an operation in which the car 1 is sequentially answered to the registered calls. If the inside of the hoistway 3 shines during automatic driving, the user may feel the light suspicious. Therefore, if the elevator is automatically operated, the selection unit 41 selects, for example, the infrared lamp 23 as a light source (S101).
　条件判定部４５は、撮影条件が成立したか否かを判定する（Ｓ１０２）。撮影条件は予め設定される。撮影条件として、特定の時間帯が設定されても良い。かかる場合、現在時刻が上記時間帯に含まれていれば、Ｓ１０２でＹｅｓと判定される。他の例として、通信部４４が特定の信号を受信すると、撮影条件が成立しても良い。他の例として、Ｓ１０２では常にＹｅｓと判定されても良い。 The condition determination unit 45 determines whether or not the shooting conditions are satisfied (S102). Shooting conditions are set in advance. A specific time zone may be set as the shooting condition. In such a case, if the current time is included in the above time zone, it is determined as Yes in S102. As another example, when the communication unit 44 receives a specific signal, the photographing condition may be satisfied. As another example, in S102, it may always be determined as Yes.
　Ｓ１０２でＹｅｓと判定されると、放射制御部４２は、赤外線ランプ２３から赤外線を放射させる。また、Ｓ１０２でＹｅｓと判定されると、カメラ２４による撮影が行われる（Ｓ１０３）。Ｓ１０２でカメラ２４による撮影が開始されると、制御装置３２では、映像データの送信を要求する要求信号を通信部４４が受信したか否かが判定される（Ｓ１０４）。 If it is determined to be Yes in S102, the radiation control unit 42 emits infrared rays from the infrared lamp 23. If Yes is determined in S102, the camera 24 takes a picture (S103). When shooting by the camera 24 is started in S102, the control device 32 determines whether or not the communication unit 44 has received the request signal requesting the transmission of video data (S104).
　通信部４４は、要求信号を受信していれば（Ｓ１０４のＹｅｓ）、要求先に映像データを送信する（Ｓ１０５）。通信部４４が要求信号を受信していなければ（Ｓ１０４のＮｏ）、映像データが記憶部４０に保存される（Ｓ１０６）。Ｓ１０５において記憶部４０への映像データの保存が同時に行われても良い。 If the communication unit 44 has received the request signal (Yes in S104), the communication unit 44 transmits the video data to the request destination (S105). If the communication unit 44 has not received the request signal (No in S104), the video data is stored in the storage unit 40 (S106). In S105, the video data may be stored in the storage unit 40 at the same time.
　選択部４１が赤外線ランプ２３を選択している間、条件判定部４５は、切替条件が成立したか否かを判定する（Ｓ１０７）。切替条件は予め設定される。切替条件として、特定の時刻が設定されても良い。かかる場合、現在時刻が上記時刻になると、１０７でＹｅｓと判定される。他の例として、通信部４４が特定の信号を受信すると、切替条件が成立しても良い。他の例として、エレベーターの運転モードに応じて切替条件が成立しても良い。選択部４１が赤外線ランプ２３を選択している時に切替条件が成立すると、選択部４１は、光源として可視光ランプ２２を選択する（Ｓ１０８）。 While the selection unit 41 selects the infrared lamp 23, the condition determination unit 45 determines whether or not the switching condition is satisfied (S107). The switching conditions are set in advance. A specific time may be set as the switching condition. In such a case, when the current time reaches the above time, 107 determines Yes. As another example, when the communication unit 44 receives a specific signal, the switching condition may be satisfied. As another example, the switching condition may be satisfied according to the operation mode of the elevator. If the switching condition is satisfied while the selection unit 41 is selecting the infrared lamp 23, the selection unit 41 selects the visible light lamp 22 as the light source (S108).
　選択部４１が可視光ランプ２２を選択すると、条件判定部４５は、撮影条件が成立したか否かを判定する（Ｓ１０９）。可視光で撮影するための撮影条件は、赤外線で撮影するための撮影条件とは異なる。例えば、通信部４４が特定の信号を受信すると、Ｓ１０９でＹｅｓと判定される。可視光で撮影するための撮影条件は、赤外線で撮影するための撮影条件と同じであっても良い。例えば、Ｓ１０９では常にＹｅｓと判定されても良い。 When the selection unit 41 selects the visible light lamp 22, the condition determination unit 45 determines whether or not the shooting conditions are satisfied (S109). The shooting conditions for shooting with visible light are different from the shooting conditions for shooting with infrared light. For example, when the communication unit 44 receives a specific signal, S109 determines Yes. The shooting conditions for shooting with visible light may be the same as the shooting conditions for shooting with infrared light. For example, in S109, it may always be determined as Yes.
　Ｓ１０９でＹｅｓと判定されると、放射制御部４２は、可視光ランプ２２から可視光を放射させる。また、Ｓ１０９でＹｅｓと判定されると、カメラ２４による撮影が行われる（Ｓ１１０）。Ｓ１１０でカメラ２４による撮影が開始されると、制御装置３２では、映像データの送信を要求する要求信号を通信部４４が受信したか否かが判定される（Ｓ１１１）。 If it is determined to be Yes in S109, the radiation control unit 42 emits visible light from the visible light lamp 22. Further, if it is determined to be Yes in S109, the camera 24 takes a picture (S110). When shooting by the camera 24 is started in S110, the control device 32 determines whether or not the communication unit 44 has received the request signal requesting the transmission of video data (S111).
　通信部４４は、要求信号を受信していれば（Ｓ１１１のＹｅｓ）、要求先に映像データを送信する（Ｓ１１２）。通信部４４が要求信号を受信していなければ（Ｓ１１１のＮｏ）、記憶部４０に映像データが保存される（Ｓ１１３）。Ｓ１１２において映像データの保存が同時に行われても良い。 If the communication unit 44 has received the request signal (Yes in S111), the communication unit 44 transmits the video data to the request destination (S112). If the communication unit 44 has not received the request signal (No in S111), the video data is stored in the storage unit 40 (S113). The video data may be saved at the same time in S112.
　選択部４１が可視光ランプ２２を選択している間も、条件判定部４５は、切替条件が成立したか否かを判定する（Ｓ１１４）。Ｓ１１４での切替条件とＳ１０７での切替条件とは異なる条件でも良い。選択部４１が可視光ランプ２２を選択している時に切替条件が成立すると、選択部４１は、光源として赤外線ランプ２３を選択する（Ｓ１０１）。 While the selection unit 41 is selecting the visible light lamp 22, the condition determination unit 45 determines whether or not the switching condition is satisfied (S114). The switching condition in S114 and the switching condition in S107 may be different from each other. If the switching condition is satisfied while the selection unit 41 is selecting the visible light lamp 22, the selection unit 41 selects the infrared lamp 23 as the light source (S101).
　カメラユニット１７の基本動作は、カメラユニット１６の基本動作と同様である。このため、カメラユニット１７の基本動作に関する説明は省略する。 The basic operation of the camera unit 17 is the same as the basic operation of the camera unit 16. Therefore, the description of the basic operation of the camera unit 17 will be omitted.

　以下に、カメラ２４で撮影された映像を利用する例について説明する。以下においては、カメラユニット１６に備えられたカメラ２４で撮影された映像を利用する例について詳しく説明する。カメラユニット１７に備えられたカメラ２４で撮影された映像を利用する例については、詳しい説明を省略する。先ず、一例として、保守員が、カメラ２４で撮影された映像を自分の携帯端末１３で見る例について説明する。 An example of using the image taken by the camera 24 will be described below. In the following, an example of using the image taken by the camera 24 provided in the camera unit 16 will be described in detail. A detailed description of the example of using the image captured by the camera 24 provided in the camera unit 17 will be omitted. First, as an example, an example in which a maintenance worker views an image taken by the camera 24 on his / her mobile terminal 13 will be described.
　例えば、カメラユニット１６では、エレベーターで自動運転が行われていれば、選択部４１が赤外線ランプ２３を選択する（Ｓ１０１）。例えば、自動運転が行われている間、Ｓ１０２ではＹｅｓと判定され、Ｓ１０４ではＮｏと判定される。かかる場合、自動運転が行われていれば、カメラ２４によって撮影された赤外線映像が記憶部４０に保存され続ける。 For example, in the camera unit 16, if the elevator is automatically operated, the selection unit 41 selects the infrared lamp 23 (S101). For example, while the automatic operation is being performed, it is determined as Yes in S102 and No in S104. In such a case, if the automatic operation is performed, the infrared image captured by the camera 24 continues to be stored in the storage unit 40.
　図８は、携帯端末１３の動作例を示すフローチャートである。携帯端末１３では、カメラユニット１６と無線接続したか否かが判定される（Ｓ２０１）。図９は、カメラユニット１６と接続した携帯端末１３の例を示す図である。図９に示す例では、携帯端末１３の表示器７１に、入力装置７０としてのボタン７０ａとボタン７０ｂとが表示される。 FIG. 8 is a flowchart showing an operation example of the mobile terminal 13. The mobile terminal 13 determines whether or not it is wirelessly connected to the camera unit 16 (S201). FIG. 9 is a diagram showing an example of a mobile terminal 13 connected to the camera unit 16. In the example shown in FIG. 9, the button 70a and the button 70b as the input device 70 are displayed on the display 71 of the mobile terminal 13.
　保守員が携帯端末１３に対して特定の操作を行うことにより、携帯端末１３がカメラユニット１６に接続される（Ｓ２０１のＹｅｓ）。携帯端末１３では、カメラユニット１６に接続されると、可視光映像の要求があるか否かが判定される（Ｓ２０２）。ボタン７０ａは、保守員が昇降路３内の可視光映像を見たい時に押すためのボタンである。ボタン７０ａが押されると、Ｓ２０２でＹｅｓと判定される。Ｓ２０２でＹｅｓと判定されると、信号生成部７３は、選択部４１に可視光ランプ２２を選択させるための第１信号を生成する（Ｓ２０３）。通信部７５は、信号生成部７３が生成した第１信号をカメラユニット１６に送信する（Ｓ２０４）。 When the maintenance staff performs a specific operation on the mobile terminal 13, the mobile terminal 13 is connected to the camera unit 16 (Yes in S201). When the mobile terminal 13 is connected to the camera unit 16, it is determined whether or not there is a request for a visible light image (S202). The button 70a is a button for a maintenance worker to press when he / she wants to see a visible light image in the hoistway 3. When the button 70a is pressed, S202 determines Yes. If it is determined to be Yes in S202, the signal generation unit 73 generates a first signal for causing the selection unit 41 to select the visible light lamp 22 (S203). The communication unit 75 transmits the first signal generated by the signal generation unit 73 to the camera unit 16 (S204).
　カメラユニット１６では、選択部４１が赤外線ランプ２３を選択している時に通信部４４が携帯端末１３から第１信号を受信すると、切替条件が成立したことを条件判定部４５が判定する（Ｓ１０７のＹｅｓ）。これにより、選択部４１は、Ｓ１０８で可視光ランプ２２を選択する。例えば、通信部４４が携帯端末１３から第１信号を受信すると、Ｓ１０９でＹｅｓと判定され、Ｓ１１１でＹｅｓと判定される。Ｓ１１２において、通信部４４は、カメラ２４による映像データを携帯端末１３に対して送信する。 In the camera unit 16, when the communication unit 44 receives the first signal from the mobile terminal 13 while the selection unit 41 is selecting the infrared lamp 23, the condition determination unit 45 determines that the switching condition is satisfied (S107). Yes). As a result, the selection unit 41 selects the visible light lamp 22 in S108. For example, when the communication unit 44 receives the first signal from the mobile terminal 13, it is determined as Yes in S109 and Yes in S111. In S112, the communication unit 44 transmits the video data from the camera 24 to the mobile terminal 13.
　携帯端末１３では、Ｓ２０４で第１信号を送信すると、カメラユニット１６から映像データを受信したか否かが判定される（Ｓ２０５）。Ｓ１１２で通信部４４が送信した映像データは、通信部７５によって受信される（Ｓ２０５のＹｅｓ）。表示制御部７４は、通信部７５がカメラユニット１６から受信した映像データに基づいて、カメラ２４によって撮影された映像、即ち可視光映像を表示器７１に表示させる（Ｓ２０６）。例えば、表示制御部７４は、カメラ２４によって撮影された映像を表示器７１の表示エリア７１ａに表示させる。 In the mobile terminal 13, when the first signal is transmitted in S204, it is determined whether or not the video data is received from the camera unit 16 (S205). The video data transmitted by the communication unit 44 in S112 is received by the communication unit 75 (Yes in S205). The display control unit 74 causes the display 71 to display an image captured by the camera 24, that is, a visible light image, based on the image data received by the communication unit 75 from the camera unit 16 (S206). For example, the display control unit 74 displays the image captured by the camera 24 in the display area 71a of the display unit 71.
　携帯端末１３とカメラユニット１６との通信が切断されていなければ（Ｓ２０７のＮｏ）、携帯端末１３の処理はＳ２０２に戻る。携帯端末１３では、Ｓ２０２でＹｅｓと判定されなければ、赤外線映像の要求があるか否かが判定される（Ｓ２０８）。ボタン７０ｂは、保守員が昇降路３内の赤外線映像を見たい時に押すためのボタンである。携帯端末１３がカメラユニット１６に接続されている時にボタン７０ｂが押されると、Ｓ２０８でＹｅｓと判定される。Ｓ２０８でＹｅｓと判定されると、信号生成部７３は、選択部４１に赤外線ランプ２３を選択させるための第２信号を生成する（Ｓ２０９）。第２信号は、上記第１信号とは異なる信号である。通信部７５は、信号生成部７３が生成した第２信号をカメラユニット１６に送信する（Ｓ２１０）。 If the communication between the mobile terminal 13 and the camera unit 16 is not disconnected (No in S207), the processing of the mobile terminal 13 returns to S202. In the mobile terminal 13, if it is not determined as Yes in S202, it is determined whether or not there is a request for an infrared image (S208). The button 70b is a button for a maintenance person to press when he / she wants to see an infrared image in the hoistway 3. If the button 70b is pressed while the mobile terminal 13 is connected to the camera unit 16, S208 determines Yes. If it is determined to be Yes in S208, the signal generation unit 73 generates a second signal for causing the selection unit 41 to select the infrared lamp 23 (S209). The second signal is a signal different from the first signal. The communication unit 75 transmits the second signal generated by the signal generation unit 73 to the camera unit 16 (S210).
　カメラユニット１６では、選択部４１が可視光ランプ２２を選択している時に通信部４４が携帯端末１３から第２信号を受信すると、切替条件が成立したことを条件判定部４５が判定する（Ｓ１１４のＹｅｓ）。これにより、選択部４１は、Ｓ１０１で赤外線ランプ２３を選択する。例えば、通信部４４が携帯端末１３から第２信号を受信すると、Ｓ１０２でＹｅｓと判定され、Ｓ１０４でＹｅｓと判定される。Ｓ１０５において、通信部４４は、カメラ２４による映像データを携帯端末１３に対して送信する。 In the camera unit 16, when the communication unit 44 receives the second signal from the mobile terminal 13 while the selection unit 41 is selecting the visible light lamp 22, the condition determination unit 45 determines that the switching condition is satisfied (S114). Yes). As a result, the selection unit 41 selects the infrared lamp 23 in S101. For example, when the communication unit 44 receives the second signal from the mobile terminal 13, it is determined as Yes in S102 and Yes in S104. In S105, the communication unit 44 transmits the video data from the camera 24 to the mobile terminal 13.
　携帯端末１３では、Ｓ２１０で第２信号を送信すると、カメラユニット１６から映像データを受信したか否かが判定される（Ｓ２０５）。Ｓ１０５で通信部４４が送信した映像データは、通信部７５によって受信される（Ｓ２０５のＹｅｓ）。表示制御部７４は、通信部７５がカメラユニット１６から受信した映像データに基づいて、カメラ２４によって撮影された映像、即ち赤外線映像を表示器７１に表示させる（Ｓ２０６）。例えば、表示制御部７４は、カメラ２４によって撮影された映像を表示器７１の表示エリア７１ａに表示させる。 In the mobile terminal 13, when the second signal is transmitted in S210, it is determined whether or not the video data is received from the camera unit 16 (S205). The video data transmitted by the communication unit 44 in S105 is received by the communication unit 75 (Yes in S205). The display control unit 74 causes the display 71 to display an image captured by the camera 24, that is, an infrared image, based on the image data received by the communication unit 75 from the camera unit 16 (S206). For example, the display control unit 74 displays the image captured by the camera 24 in the display area 71a of the display unit 71.
　携帯端末１３とカメラユニット１６との通信が切断されると（Ｓ２０７のＹｅｓ）、携帯端末１３は処理を終了する。カメラユニット１６では、携帯端末１３との通信が切断されると、例えば選択部４１が赤外線ランプ２３を選択する。 When the communication between the mobile terminal 13 and the camera unit 16 is disconnected (Yes in S207), the mobile terminal 13 ends the process. In the camera unit 16, when the communication with the mobile terminal 13 is disconnected, for example, the selection unit 41 selects the infrared lamp 23.
　図１０は、携帯端末１３の他の動作例を示すフローチャートである。携帯端末１３が図１０に示す動作を行う場合、カメラユニット１６の制御装置３２には通信検出部４６が備えられる。通信検出部４６は、通信部４４と特定の機器との通信が確立したことを検出する。 FIG. 10 is a flowchart showing another operation example of the mobile terminal 13. When the mobile terminal 13 performs the operation shown in FIG. 10, the control device 32 of the camera unit 16 is provided with a communication detection unit 46.

When the mobile terminal 13 is connected to the camera unit 16, the mobile terminal 13 determines whether or not video data has been received from the camera unit 16 (S302).
　カメラユニット１６では、例えばエレベーターで自動運転が行われていれば、選択部４１が赤外線ランプ２３を選択する（Ｓ１０１）。例えば、自動運転が行われている間、カメラ２４によって撮影された赤外線映像が記憶部４０に保存される。また、携帯端末１３がカメラユニット１６に接続されると、通信部４４と携帯端末１３との通信が確立したことが通信検出部４６によって検出される。 In the camera unit 16, for example, if the elevator is automatically operating, the selection unit 41 selects the infrared lamp 23 (S101). For example, the infrared image captured by the camera 24 is stored in the storage unit 40 while the automatic operation is being performed. Further, when the mobile terminal 13 is connected to the camera unit 16, the communication detection unit 46 detects that the communication between the communication unit 44 and the mobile terminal 13 has been established.

The display control unit 74 displays the visible light image captured by the camera 24 in the display area 71a of the display unit 71 based on the image data received from the camera unit 16 by the communication unit 75 (S303).
　次に、携帯端末１３では、赤外線映像の要求があるか否かが判定される（Ｓ３０４）。例えば、ボタン７０ｂが押されると、Ｓ３０４でＹｅｓと判定される。Ｓ３０４でＹｅｓと判定されると、信号生成部７３は、選択部４１に赤外線ランプ２３を選択させるための第２信号を生成する（Ｓ３０５）。通信部７５は、信号生成部７３が生成した第２信号をカメラユニット１６に送信する（Ｓ３０６）。 Next, the mobile terminal 13 determines whether or not there is a request for an infrared image (S304). For example, when the button 70b is pressed, S304 determines Yes. If it is determined to be Yes in S304, the signal generation unit 73 generates a second signal for causing the selection unit 41 to select the infrared lamp 23 (S305). The communication unit 75 transmits the second signal generated by the signal generation unit 73 to the camera unit 16 (S306).
　カメラユニット１６では、選択部４１が可視光ランプ２２を選択している時に通信部４４が携帯端末１３から第２信号を受信すると、切替条件が成立したことを条件判定部４５が判定する（Ｓ１１４のＹｅｓ）。これにより、選択部４１は、Ｓ１０１で赤外線ランプ２３を選択する。例えば、通信部４４が携帯端末１３から第２信号を受信すると、Ｓ１０２でＹｅｓと判定され、Ｓ１０４でＹｅｓと判定される。Ｓ１０５において、通信部４４は、カメラ２４による映像データを携帯端末１３に対して送信する。 In the camera unit 16, when the communication unit 44 receives the second signal from the mobile terminal 13 while the selection unit 41 is selecting the visible light lamp 22, the condition determination unit 45 determines that the switching condition is satisfied (S114).

For example, when the button 70a is pressed, S308 determines Yes. If it is determined to be Yes in S308, the signal generation unit 73 generates a first signal for causing the selection unit 41 to select the visible light lamp 22 (S309). The communication unit 75 transmits the first signal generated by the signal generation unit 73 to the camera unit 16 (S310). As a result, the visible light image captured by the camera 24 can be displayed in the display area 71a.
　携帯端末１３とカメラユニット１６との通信が切断されると（Ｓ３０７のＹｅｓ）、携帯端末１３は処理を終了する。カメラユニット１６では、携帯端末１３との通信が切断されると、例えば選択部４１が赤外線ランプ２３を選択する。 When the communication between the mobile terminal 13 and the camera unit 16 is disconnected (Yes in S307), the mobile terminal 13 ends the process. In the camera unit 16, when the communication with the mobile terminal 13 is disconnected, for example, the selection unit 41 selects the infrared lamp 23.
　なお、上記では、カメラユニット１６の通信部４４が、カメラ２４による映像データを無線で携帯端末１３に直接送信する例について説明した。これは一例である。通信部４４は、映像データをアクセスポイント１２を介して携帯端末１３に無線で送信しても良い。他の例として、通信部４４は、映像データをソケット１８を介した電力線通信を用いて携帯端末１３に送信しても良い。 In the above description, an example in which the communication unit 44 of the camera unit 16 wirelessly transmits the video data by the camera 24 directly to the mobile terminal 13 has been described. This is just an example. The communication unit 44 may wirelessly transmit the video data to the mobile terminal 13 via the access point 12. As another example, the communication unit 44 may transmit the video data to the mobile terminal 13 using the power line communication via the socket 18.
　また、上記では、カメラユニット１６の通信部４４が、カメラ２４による映像データのみを携帯端末１３に送信する例について説明した。これは一例である。通信部４４は、映像データとともに他のデータを携帯端末１３に送信しても良い。例えば、通信部４４は、映像データとともに、音のデータ、加速度のデータ、角速度のデータ、気圧のデータ、温度のデータ、及び湿度のデータのうちの１つ或いは複数を送信しても良い。 Further, in the above, an example in which the communication unit 44 of the camera unit 16 transmits only the video data obtained by the camera 24 to the mobile terminal 13 has been described. This is just an example. The communication unit 44 may transmit other data together with the video data to the mobile terminal 13. For example, the communication unit 44 may transmit one or more of sound data, acceleration data, angular velocity data, barometric pressure data, temperature data, and humidity data together with video data.
　例えば、保守員は、携帯端末１３で受信した加速度のデータ又は角速度のデータに基づいて、乗り心地に問題がないかを確認することができる。 For example, the maintenance staff can confirm that there is no problem in riding comfort based on the acceleration data or the angular velocity data received by the mobile terminal 13.
　他の例として、携帯端末１３で受信した気圧のデータに基づいて、保守員がいる位置を特定することができる。例えば、携帯端末１３にも気圧計（図示せず）が備えられていれば、かご１の位置を基準にして、気圧計２９が検出した気圧と携帯端末１３に備えられた気圧計が検出した気圧との差を用いて、保守員がいる位置をより正確に特定することが可能となる。 As another example, the position where the maintenance staff is located can be specified based on the atmospheric pressure data received by the mobile terminal 13. For example, if the mobile terminal 13 is also equipped with a barometer (not shown), the barometer detected by the barometer 29 and the barometer provided in the mobile terminal 13 are detected based on the position of the car 1. The difference from the atmospheric pressure can be used to more accurately identify the location of the maintenance personnel.
　他の例として、携帯端末１３で受信した温度データ及び湿度データに基づいて、エレベーターの使用環境を特定することができる。例えば、温度データ及び湿度データを用いることにより、制御装置７等に備えられた基板の寿命予測を行うことができる。 As another example, the usage environment of the elevator can be specified based on the temperature data and the humidity data received by the mobile terminal 13. For example, by using the temperature data and the humidity data, it is possible to predict the life of the substrate provided in the control device 7 or the like.
　次に、カメラ２４で撮影された映像を利用する他の例として、監視センター１０にいる監視員が、カメラ２４で撮影された映像を外部機器１１で見る例について説明する。 Next, as another example of using the image captured by the camera 24, an example in which the observer in the monitoring center 10 views the image captured by the camera 24 on the external device 11 will be described.
　例えば、カメラユニット１６では、エレベーターで自動運転が行われていれば、選択部４１が赤外線ランプ２３を選択する（Ｓ１０１）。例えば、自動運転が行われている間、カメラ２４によって撮影された赤外線映像が記憶部４０に保存される。 For example, in the camera unit 16, if the elevator is automatically operated, the selection unit 41 selects the infrared lamp 23 (S101). For example, the infrared image captured by the camera 24 is stored in the storage unit 40 while the automatic operation is being performed.
　外部機器１１では、図８に示す動作と同様の動作が行われる。例えば、外部機器１１では、カメラユニット１６と接続したか否かが判定される（Ｓ２０１）。監視センター１０の監視員は、カメラ２４によって撮影された映像を表示器８１で見たい時に、外部機器１１をカメラユニット１６に接続する。例えば、外部機器１１と監視装置８とは、ネットワーク９を介して有線接続される。監視装置８とカメラユニット１６とは、アクセスポイント１２を介して無線接続される。 In the external device 11, the same operation as that shown in FIG. 8 is performed. For example, in the external device 11, it is determined whether or not the camera unit 16 is connected (S201). The observer of the monitoring center 10 connects the external device 11 to the camera unit 16 when he / she wants to see the image taken by the camera 24 on the display 81. For example, the external device 11 and the monitoring device 8 are connected by wire via the network 9.

For example, when the observer superimposes the pointer 80c on the button 80a and clicks it, S202 determines Yes. If it is determined to be Yes in S202, the signal generation unit 83 generates a first signal for causing the selection unit 41 to select the visible light lamp 22 (S203). The communication unit 85 transmits the first signal generated by the signal generation unit 83 to the camera unit 16 (S204).
　カメラユニット１６では、選択部４１が赤外線ランプ２３を選択している時に通信部４４が外部機器１１から第１信号を受信すると、切替条件が成立したことを条件判定部４５が判定する（Ｓ１０７のＹｅｓ）。これにより、選択部４１は、Ｓ１０８で可視光ランプ２２を選択する。例えば、通信部４４が外部機器１１から第１信号を受信すると、Ｓ１０９でＹｅｓと判定され、Ｓ１１１でＹｅｓと判定される。Ｓ１１２において、通信部４４は、カメラ２４による映像データを外部機器１１に対して送信する。具体的に、通信部４４は、映像データをアクセスポイント１２を介して監視装置８に送信する。監視装置８は、アクセスポイント１２を介してカメラユニット１６から受信した映像データを、ネットワーク９を介して外部機器１１に送信する。 In the camera unit 16, when the communication unit 44 receives the first signal from the external device 11 while the selection unit 41 is selecting the infrared lamp 23, the condition determination unit 45 determines that the switching condition is satisfied (S107).

For example, when the communication unit 44 receives the first signal from the external device 11, it is determined as Yes in S109 and Yes in S111. In S112, the communication unit 44 transmits the video data from the camera 24 to the external device 11. Specifically, the communication unit 44 transmits the video data to the monitoring device 8 via the access point 12. The monitoring device 8 transmits the video data received from the camera unit 16 via the access point 12 to the external device 11 via the network 9.

　外部機器１１とカメラユニット１６との通信が切断されていなければ（Ｓ２０７のＮｏ）、外部機器１１の処理はＳ２０２に戻る。外部機器１１では、Ｓ２０２でＹｅｓと判定されなければ、赤外線映像の要求があるか否かが判定される（Ｓ２０８）。外部機器１１がカメラユニット１６に接続されている時にボタン８０ｂがクリックされると、Ｓ２０８でＹｅｓと判定される。Ｓ２０８でＹｅｓと判定されると、信号生成部８３は、選択部４１に赤外線ランプ２３を選択させるための第２信号を生成する（Ｓ２０９）。通信部８５は、信号生成部８３が生成した第２信号をカメラユニット１６に送信する（Ｓ２１０）。 If the communication between the external device 11 and the camera unit 16 is not disconnected (No in S207), the processing of the external device 11 returns to S202. In the external device 11, if it is not determined as Yes in S202, it is determined whether or not there is a request for an infrared image (S208). If the button 80b is clicked while the external device 11 is connected to the camera unit 16, S208 determines Yes. If it is determined to be Yes in S208, the signal generation unit 83 generates a second signal for causing the selection unit 41 to select the infrared lamp 23 (S209). The communication unit 85 transmits the second signal generated by the signal generation unit 83 to the camera unit 16 (S210).
　カメラユニット１６では、選択部４１が可視光ランプ２２を選択している時に通信部４４が外部機器１１から第２信号を受信すると、切替条件が成立したことを条件判定部４５が判定する（Ｓ１１４のＹｅｓ）。これにより、選択部４１は、Ｓ１０１で赤外線ランプ２３を選択する。例えば、通信部４４が外部機器１１から第２信号を受信すると、Ｓ１０２でＹｅｓと判定され、Ｓ１０４でＹｅｓと判定される。Ｓ１０５において、通信部４４は、カメラ２４による映像データを外部機器１１に対して送信する。具体的に、通信部４４は、映像データをアクセスポイント１２を介して監視装置８に送信する。監視装置８は、アクセスポイント１２を介してカメラユニット１６から受信した映像データを、ネットワーク９を介して外部機器１１に送信する。 In the camera unit 16, when the communication unit 44 receives the second signal from the external device 11 while the selection unit 41 is selecting the visible light lamp 22, the condition determination unit 45 determines that the switching condition is satisfied (S114).

For example, the display control unit 84 displays the image captured by the camera 24 in the display area 81a of the display 81.
　外部機器１１とカメラユニット１６との通信が切断されると（Ｓ２０７のＹｅｓ）、外部機器１１は処理を終了する。カメラユニット１６では、外部機器１１との通信が切断されると、例えば選択部４１が赤外線ランプ２３を選択する。 When the communication between the external device 11 and the camera unit 16 is disconnected (Yes in S207), the external device 11 ends the process. In the camera unit 16, when the communication with the external device 11 is cut off, for example, the selection unit 41 selects the infrared lamp 23.
　外部機器１１では、図１０に示す動作と同様の動作が行われても良い。かかる場合、カメラユニット１６の制御装置３２には通信検出部４６が備えられる。即ち、選択部４１が赤外線ランプ２３を選択している時に通信部４４と外部機器１１との通信が確立したことが通信検出部４６によって検出されると、Ｓ１０７において切替条件が成立したことが判定される。これにより、カメラ２４によって撮影された映像、即ち可視光映像が表示器８１の表示エリア８１ａに表示される（Ｓ３０３）。 The external device 11 may perform the same operation as that shown in FIG. In such a case, the control device 32 of the camera unit 16 is provided with a communication detection unit 46.

　次に、カメラ２４によって撮影された映像をエレベーターの運転モードに応じて利用する例について説明する。図１２は、監視装置８の動作例を示すフローチャートである。例えば、制御装置７の運転制御部５１で自動運転が行われる間、監視装置８では、条件判定部６１が、診断条件が成立したか否かを判定する（Ｓ４０１）。診断条件は予め設定される。例えば、特定の日の特定の時刻になると、診断条件が成立する。診断条件が成立したことを条件判定部６１が判定すると（Ｓ４０１のＹｅｓ）、通信部６２は、運転モードを診断モードに設定するための第１モード信号を制御装置７及びカメラユニット１６に送信する（Ｓ４０２）。 Next, an example of using the image captured by the camera 24 according to the operation mode of the elevator will be described. FIG. 12 is a flowchart showing an operation example of the monitoring device 8. For example, in the monitoring device 8, the condition determination unit 61 determines whether or not the diagnostic condition is satisfied while the operation control unit 51 of the control device 7 performs the automatic operation (S401). Diagnostic conditions are preset. For example, the diagnostic condition is satisfied at a specific time on a specific day. When the condition determination unit 61 determines that the diagnosis condition is satisfied (Yes in S401), the communication unit 62 transmits a first mode signal for setting the operation mode to the diagnosis mode to the control device 7 and the camera unit 16. (S402).
　制御装置７では、監視装置８から第１モード信号を受信すると、診断運転を開始する。即ち、運転制御部５１は、診断条件が成立すると診断運転を行う。診断運転では、異常の有無を判定するために必要な診断用データが取得される。制御装置７は、診断運転で取得した診断用データを監視装置８に送信する。 When the control device 7 receives the first mode signal from the monitoring device 8, the diagnostic operation is started. That is, the operation control unit 51 performs a diagnostic operation when the diagnostic conditions are satisfied. In the diagnostic operation, diagnostic data necessary for determining the presence or absence of an abnormality is acquired. The control device 7 transmits the diagnostic data acquired in the diagnostic operation to the monitoring device 8.
　また、カメラユニット１６では、エレベーターで自動運転が行われていれば、選択部４１が赤外線ランプ２３を選択する（Ｓ１０１）。例えば、自動運転が行われている間、カメラ２４によって撮影された赤外線映像が記憶部４０に保存される。 Further, in the camera unit 16, if the elevator is automatically operated, the selection unit 41 selects the infrared lamp 23 (S101). For example, the infrared image captured by the camera 24 is stored in the storage unit 40 while the automatic operation is being performed.
　選択部４１が赤外線ランプ２３を選択している時に通信部４４が監視装置８から第１モード信号を受信すると、切替条件が成立したことを条件判定部４５が判定する（Ｓ１０７のＹｅｓ）。これにより、選択部４１は、Ｓ１０８で可視光ランプ２２を選択する。即ち、エレベーターで診断運転が行われると、選択部４１は可視光ランプ２２を選択する。例えば、通信部４４が監視装置８から第１モード信号を受信すると、Ｓ１０９でＹｅｓと判定され、Ｓ１１１でＹｅｓと判定される。Ｓ１１２において、通信部４４は、カメラ２４による映像データを診断用データとして監視装置８に送信する。 When the communication unit 44 receives the first mode signal from the monitoring device 8 while the selection unit 41 is selecting the infrared lamp 23, the condition determination unit 45 determines that the switching condition is satisfied (Yes in S107). As a result, the selection unit 41 selects the visible light lamp 22 in S108. That is, when the diagnostic operation is performed in the elevator, the selection unit 41 selects the visible light lamp 22. For example, when the communication unit 44 receives the first mode signal from the monitoring device 8, it is determined as Yes in S109 and Yes in S111. In S112, the communication unit 44 transmits the video data obtained by the camera 24 to the monitoring device 8 as diagnostic data.
　監視装置８では、Ｓ４０２で通信部６２が第１モード信号を送信すると、診断用データを受信したか否かが判定される（Ｓ４０３）。制御装置７が送信した診断用データは、通信部６２によって受信される（Ｓ４０３のＹｅｓ）。Ｓ１１２で通信部４４が送信した映像データ（診断用データ）は、通信部６２によって受信される（Ｓ４０３のＹｅｓ）。通信部６２が受信した診断用データは、記憶部６０に記憶される（Ｓ４０４）。 In the monitoring device 8, when the communication unit 62 transmits the first mode signal in S402, it is determined whether or not the diagnostic data has been received (S403). The diagnostic data transmitted by the control device 7 is received by the communication unit 62 (Yes in S403). The video data (diagnosis data) transmitted by the communication unit 44 in S112 is received by the communication unit 62 (Yes in S403). The diagnostic data received by the communication unit 62 is stored in the storage unit 60 (S404).
　運転制御部５１による診断運転が終了すると（Ｓ４０５のＹｅｓ）、通信部６２は、運転モードを自動モードに設定するための第２モード信号を制御装置７及びカメラユニット１６に送信する（Ｓ４０６）。制御装置７では、監視装置８から第２モード信号を受信すると、運転制御部５１が自動運転を再開する。 When the diagnostic operation by the operation control unit 51 is completed (Yes in S405), the communication unit 62 transmits a second mode signal for setting the operation mode to the automatic mode to the control device 7 and the camera unit 16 (S406). In the control device 7, when the second mode signal is received from the monitoring device 8, the operation control unit 51 restarts the automatic operation.
　カメラユニット１６では、選択部４１が可視光ランプ２２を選択している時に通信部４４が監視装置８から第２モード信号を受信すると、切替条件が成立したことを条件判定部４５が判定する（Ｓ１１４のＹｅｓ）。これにより、選択部４１は、Ｓ１０１で赤外線ランプ２３を選択する。即ち、エレベーターで自動運転が再開されると、カメラ２４による赤外線映像が記憶部４０に保存される。この例であれば、診断用データに、カメラ２４による映像データを含めることができる。 In the camera unit 16, when the communication unit 44 receives the second mode signal from the monitoring device 8 while the selection unit 41 is selecting the visible light lamp 22, the condition determination unit 45 determines that the switching condition is satisfied ( Yes of S114). As a result, the selection unit 41 selects the infrared lamp 23 in S101. That is, when the automatic operation is restarted by the elevator, the infrared image taken by the camera 24 is stored in the storage unit 40. In this example, the diagnostic data can include video data from the camera 24.
　図１３は、監視装置８の他の動作例を示すフローチャートである。図１３は、図１２に示す動作とは別に行われる動作の例を示す。図１３は、診断運転で取得された診断用データに基づいて、監視センター１０において異常の有無を判定する例を示す。 FIG. 13 is a flowchart showing another operation example of the monitoring device 8. FIG. 13 shows an example of an operation performed separately from the operation shown in FIG. FIG. 13 shows an example of determining the presence or absence of an abnormality at the monitoring center 10 based on the diagnostic data acquired in the diagnostic operation.
　監視装置８では、診断用データを要求する要求信号を監視センター１０の外部機器１１から受信したか否かが判定される（Ｓ５０１）。監視センター１０では、診断用データに基づいて異常の有無を判定するために監視装置８から診断用データを取得する必要がある。このため、外部機器１１から監視装置８に対して定期的に要求信号が送信される。 The monitoring device 8 determines whether or not a request signal requesting diagnostic data has been received from the external device 11 of the monitoring center 10 (S501). The monitoring center 10 needs to acquire diagnostic data from the monitoring device 8 in order to determine the presence or absence of an abnormality based on the diagnostic data. Therefore, the request signal is periodically transmitted from the external device 11 to the monitoring device 8.
　監視装置８では、外部機器１１から要求信号を受信すると、通信部６２が、記憶部６０に記憶されている診断用データを外部機器１１に送信する（Ｓ５０２）。外部機器１１では、監視装置８から取得した診断用データに基づいて、異常の有無を判定する。 In the monitoring device 8, when the request signal is received from the external device 11, the communication unit 62 transmits the diagnostic data stored in the storage unit 60 to the external device 11 (S502). The external device 11 determines the presence or absence of an abnormality based on the diagnostic data acquired from the monitoring device 8.
　図１４は、監視装置８の他の動作例を示すフローチャートである。図１４は、図１２に示す動作の後に行われる動作の例を示す。図１４は、診断運転で取得された診断用データに基づいて、監視装置８において異常の有無を判定する例を示す。図１４に示す動作が行われる場合、監視装置８には異常検出部６３が備えられる。 FIG. 14 is a flowchart showing another operation example of the monitoring device 8. FIG. 14 shows an example of an operation performed after the operation shown in FIG. FIG. 14 shows an example of determining the presence or absence of an abnormality in the monitoring device 8 based on the diagnostic data acquired in the diagnostic operation. When the operation shown in FIG. 14 is performed, the monitoring device 8 is provided with an abnormality detection unit 63.
　監視装置８では、異常検出部６３が、記憶部６０に記憶された診断用データに基づいて、異常があるか否かを判定する（Ｓ６０１）。例えば、異常検出部６３は、診断用データと対応する基準値とを比較することにより、異常を検出する。異常検出部６３によって異常が検出されると（Ｓ６０１のＹｅｓ）、通信部６２は、異常が検出されたことを示す信号を外部機器１１に送信する（Ｓ６０２）。 In the monitoring device 8, the abnormality detection unit 63 determines whether or not there is an abnormality based on the diagnostic data stored in the storage unit 60 (S601). For example, the abnormality detection unit 63 detects an abnormality by comparing the diagnostic data with the corresponding reference value. When the abnormality is detected by the abnormality detection unit 63 (Yes in S601), the communication unit 62 transmits a signal indicating that the abnormality has been detected to the external device 11 (S602).
　次に、カメラ２４によって撮影された映像を運転モードに応じて利用する他の例について説明する。図１５は、監視装置８の他の動作例を示すフローチャートである。例えば、制御装置７の運転制御部５１で自動運転が行われている間、監視装置８では、地震が発生したか否かが判定される（Ｓ７０１）。地震計１４から特定のレベルを示す加速度のデータが入力されると、Ｓ７０１でＹｅｓと判定される。地震計１４が地震検知信号を出力する場合は、地震計１４から地震検知信号が入力されると、Ｓ７０１でＹｅｓと判定される。Ｓ７０１でＹｅｓと判定されると、通信部６２は、運転モードを管制モードに設定するための第３モード信号を制御装置７に送信する（Ｓ７０２）。 Next, another example of using the image captured by the camera 24 according to the operation mode will be described. FIG. 15 is a flowchart showing another operation example of the monitoring device 8. For example, while the operation control unit 51 of the control device 7 is performing automatic operation, the monitoring device 8 determines whether or not an earthquake has occurred (S701). When the acceleration data indicating a specific level is input from the seismograph 14, it is determined as Yes in S701. When the seismograph 14 outputs an earthquake detection signal, when the seismic detection signal is input from the seismograph 14, it is determined as Yes in S701. If it is determined to be Yes in S701, the communication unit 62 transmits a third mode signal for setting the operation mode to the control mode to the control device 7 (S702).
　制御装置７では、監視装置８から第３モード信号を受信すると、地震管制運転を開始する。地震管制運転は、地震が発生した直後に、かご１の中にいる乗客を避難させるための運転である。地震管制運転では、例えば、かご１が最寄り階に停止され、ドア３７の開閉が行われる。 When the control device 7 receives the third mode signal from the monitoring device 8, the seismic control operation is started. Seismic control operation is an operation for evacuating passengers in the car 1 immediately after an earthquake occurs. In the seismic control operation, for example, the car 1 is stopped at the nearest floor and the door 37 is opened and closed.
　監視装置８では、Ｓ７０２で第３モード信号を送信すると、条件判定部６１が、復旧条件が成立したか否かを判定する（Ｓ７０３）。復旧条件は予め設定される。例えば、地震計１４で特定のレベルを示す加速度が検出され且つ地震管制運転が終了した後にかご１が無人になると、復旧条件が成立する。復旧条件が成立したことを条件判定部６１が判定すると（Ｓ７０３のＹｅｓ）、通信部６２は、運転モードを復旧モードに設定するための第４モード信号を制御装置７及びカメラユニット１６に送信する（Ｓ７０４）。 In the monitoring device 8, when the third mode signal is transmitted in S702, the condition determination unit 61 determines whether or not the recovery condition is satisfied (S703). Recovery conditions are preset. For example, when the seismograph 14 detects an acceleration indicating a specific level and the car 1 becomes unmanned after the seismic control operation is completed, the restoration condition is satisfied. When the condition determination unit 61 determines that the restoration condition is satisfied (Yes in S703), the communication unit 62 transmits a fourth mode signal for setting the operation mode to the restoration mode to the control device 7 and the camera unit 16. (S704).
　制御装置７では、監視装置８から第４モード信号を受信すると、復旧運転を開始する。即ち、運転制御部５１は、復旧条件が成立すると復旧運転を行う。復旧運転では、エレベーターの復旧の可否を判定するために必要な復旧用データが取得される。制御装置７は、復旧運転で取得した復旧用データを監視装置８に送信する。 When the control device 7 receives the fourth mode signal from the monitoring device 8, the recovery operation is started. That is, the operation control unit 51 performs the restoration operation when the restoration condition is satisfied. In the restoration operation, restoration data necessary for determining whether or not the elevator can be restored is acquired. The control device 7 transmits the recovery data acquired in the recovery operation to the monitoring device 8.
　また、カメラユニット１６では、エレベーターで自動運転が行われていれば、選択部４１が赤外線ランプ２３を選択する（Ｓ１０１）。例えば、自動運転が行われている間、カメラ２４によって撮影された赤外線映像が記憶部４０に保存される。 Further, in the camera unit 16, if the elevator is automatically operated, the selection unit 41 selects the infrared lamp 23 (S101). For example, the infrared image captured by the camera 24 is stored in the storage unit 40 while the automatic operation is being performed.
　選択部４１が赤外線ランプ２３を選択している時に通信部４４が監視装置８から第４モード信号を受信すると、切替条件が成立したことを条件判定部４５が判定する（Ｓ１０７のＹｅｓ）。これにより、選択部４１は、Ｓ１０８で可視光ランプ２２を選択する。即ち、エレベーターで復旧運転が行われると、選択部４１は可視光ランプ２２を選択する。例えば、通信部４４が監視装置８から第４モード信号を受信すると、Ｓ１０９でＹｅｓと判定され、Ｓ１１１でＹｅｓと判定される。Ｓ１１２において、通信部４４は、カメラ２４による映像データを復旧用データとして監視装置８に送信する。 When the communication unit 44 receives the fourth mode signal from the monitoring device 8 while the selection unit 41 is selecting the infrared lamp 23, the condition determination unit 45 determines that the switching condition is satisfied (Yes in S107). As a result, the selection unit 41 selects the visible light lamp 22 in S108. That is, when the restoration operation is performed by the elevator, the selection unit 41 selects the visible light lamp 22. For example, when the communication unit 44 receives the fourth mode signal from the monitoring device 8, it is determined as Yes in S109 and Yes in S111. In S112, the communication unit 44 transmits the video data obtained by the camera 24 to the monitoring device 8 as recovery data.
　監視装置８では、Ｓ７０４で通信部６２が第４モード信号を送信すると、復旧用データを受信したか否かが判定される（Ｓ７０５）。制御装置７が送信した復旧用データは、通信部６２によって受信される（Ｓ７０５のＹｅｓ）。Ｓ１１２で通信部４４が送信した映像データ（復旧用データ）は、通信部６２によって受信される（Ｓ７０５のＹｅｓ）。通信部６２が受信した復旧用データは、記憶部６０に記憶される（Ｓ７０６）。この例であれば、復旧用データに、カメラ２４による映像データを含めることができる。 In the monitoring device 8, when the communication unit 62 transmits the fourth mode signal in S704, it is determined whether or not the recovery data has been received (S705). The recovery data transmitted by the control device 7 is received by the communication unit 62 (Yes in S705). The video data (recovery data) transmitted by the communication unit 44 in S112 is received by the communication unit 62 (Yes in S705). The recovery data received by the communication unit 62 is stored in the storage unit 60 (S706). In this example, the recovery data can include video data from the camera 24.
　異常検出部６３は、記憶部６０に記憶された復旧用データに基づいて、異常があるか否かを判定する（Ｓ７０７）。例えば、異常検出部６３は、復旧用データと対応する基準値とを比較することにより、異常を検出する。異常検出部６３によって異常が検出されると（Ｓ７０７のＹｅｓ）、通信部６２は、異常が検出されたことを示す信号を外部機器１１に送信する（Ｓ７０８）。 The abnormality detection unit 63 determines whether or not there is an abnormality based on the recovery data stored in the storage unit 60 (S707). For example, the abnormality detection unit 63 detects an abnormality by comparing the recovery data with the corresponding reference value. When the abnormality is detected by the abnormality detection unit 63 (Yes in S707), the communication unit 62 transmits a signal indicating that the abnormality has been detected to the external device 11 (S708).
　異常検出部６３によって異常が検出されることなく復旧運転が終了すると（Ｓ７０９のＹｅｓ）、監視装置８は、エレベーターを仮復旧させる（Ｓ７１０）。仮復旧では、運転制御部５１は、例えば、速度制限等の一定の制限を設けた上で、登録された呼びにかご１を順次応答させる運転を行う。また、表示制御部５２は、完全な復帰ではない旨を表示器３９に表示させる。 When the restoration operation is completed without the abnormality being detected by the abnormality detection unit 63 (Yes in S709), the monitoring device 8 temporarily restores the elevator (S710). In the temporary restoration, the operation control unit 51 performs an operation in which the car 1 is sequentially answered to the registered calls after setting a certain limit such as a speed limit. Further, the display control unit 52 causes the display 39 to indicate that the restoration is not complete.
　Ｓ７０９でＹｅｓと判定されると、監視装置８は、カメラユニット１６から終了後映像データを取得する。終了後映像データは、復旧運転が終了した後にカメラ２４によって撮影された映像を表すデータである。終了後映像データは、可視光映像のデータであることが好ましい。監視装置８がカメラユニット１６から終了後映像データを取得すると、通信部６２は、取得した終了後映像データを外部機器１１に送信する（Ｓ７１１）。 If it is determined to be Yes in S709, the monitoring device 8 acquires video data from the camera unit 16 after completion. The post-completion video data is data representing the video taken by the camera 24 after the restoration operation is completed. After the end, the video data is preferably visible light video data. When the monitoring device 8 acquires the acquired video data from the camera unit 16 after the end, the communication unit 62 transmits the acquired video data to the external device 11 (S711).
　Ｓ７１１で終了後映像データを外部機器１１に送信すると、監視装置８では、外部機器１１から復旧許可信号を受信したか否かが判定される（Ｓ７１２）。監視センター１０では、外部機器１１が受信した終了後映像データに基づいて、エレベーターを本復旧させても良いか否かが判定される。この判定は、例えば、映像を見た複数の人によって行われても良い。エレベーターを本復旧させても良いと判定されると、外部機器１１から復旧許可信号が送信される。 When the video data is transmitted to the external device 11 after the end in S711, the monitoring device 8 determines whether or not the recovery permission signal has been received from the external device 11 (S712). The monitoring center 10 determines whether or not the elevator may be fully restored based on the post-completion video data received by the external device 11. This determination may be made by, for example, a plurality of people who have viewed the video. When it is determined that the elevator may be fully restored, a restoration permission signal is transmitted from the external device 11.
　監視装置８は、外部機器１１から復旧許可信号を受信すると（Ｓ７１２のＹｅｓ）、エレベーターを本復旧させる（Ｓ７１３）。本復旧では、例えば、通信部６２が第２モード信号を制御装置７及びカメラユニット１６に送信する。これにより、運転制御部５１が通常運転を再開する。表示制御部５２は、完全な復旧ではない旨の表示を表示器３９から消去する。また、カメラユニット１６では、選択部４１が赤外線ランプ２３を選択する。 When the monitoring device 8 receives the restoration permission signal from the external device 11 (Yes in S712), the monitoring device 8 actually restores the elevator (S713). In this restoration, for example, the communication unit 62 transmits the second mode signal to the control device 7 and the camera unit 16. As a result, the operation control unit 51 resumes normal operation. The display control unit 52 erases the display indicating that the restoration is not complete from the display 39. Further, in the camera unit 16, the selection unit 41 selects the infrared lamp 23.
　図１５では、監視装置８が外部機器１１から復旧許可信号を受信することによってエレベーターが本復旧する例について説明した。これは一例である。例えば、現場に訪れた保守員が特定の操作を行うことにより、エレベーターを手動で本復旧させても良い。また、地震計１４が制御装置７に接続される場合は、図１５に示す動作フローは制御装置７で行われても良い。 FIG. 15 has described an example in which the elevator is fully restored by receiving the restoration permission signal from the external device 11 by the monitoring device 8. This is just an example. For example, the elevator may be manually restored by a maintenance worker who visits the site to perform a specific operation. Further, when the seismograph 14 is connected to the control device 7, the operation flow shown in FIG. 15 may be performed by the control device 7.
　図１６は、監視装置８の他の動作例を示すフローチャートである。図１６に示す動作は、図１５に示す動作と比較し、Ｓ７０３でＮｏと判定された場合の動作が相違する。図１６は、Ｓ７０３でＮｏと判定された場合に、カメラ２４によって撮影された映像を利用する例を示す。 FIG. 16 is a flowchart showing another operation example of the monitoring device 8. The operation shown in FIG. 16 is different from the operation shown in FIG. 15 when No is determined in S703. FIG. 16 shows an example of using the image captured by the camera 24 when No is determined in S703.
　上述したように、Ｓ７０３では復旧条件が成立したか否かが判定される。例えば、地震管制運転が終了してから一定時間が経過してもＳ７０３でＹｅｓと判定されなければ、監視装置８は、カメラユニット１６から停止後映像データを取得する。停止後映像データは、地震管制運転が終了した後、かご１が停止している時にカメラ２４によって撮影された映像を表すデータである。停止後映像データは、可視光映像のデータであることが好ましい。監視装置８がカメラユニット１６から停止後映像データを取得すると、通信部６２は、取得した停止後映像データを外部機器１１に送信する（Ｓ７１４）。 As described above, in S703, it is determined whether or not the recovery condition is satisfied. For example, if S703 does not determine Yes even after a certain period of time has passed since the seismic control operation was completed, the monitoring device 8 acquires video data after stopping from the camera unit 16. The post-stop video data is data representing a video taken by the camera 24 when the car 1 is stopped after the seismic control operation is completed. The video data after stopping is preferably visible light video data. When the monitoring device 8 acquires the video data after the stop from the camera unit 16, the communication unit 62 transmits the acquired video data after the stop to the external device 11 (S714).
　Ｓ７１４で停止後映像データを外部機器１１に送信すると、監視装置８では、外部機器１１から開始信号を受信したか否かが判定される（Ｓ７１５）。監視センター１０では、外部機器１１が受信した停止後映像データに基づいて、エレベーターにおいて復旧運転を開始しても良いか否かが判定される。この判定は、例えば、映像を見た複数の人によって行われても良い。エレベーターにおいて復旧運転を開始しても良いと判定されると、外部機器１１から開始信号が送信される。 When the video data is transmitted to the external device 11 after the stop in S714, the monitoring device 8 determines whether or not the start signal has been received from the external device 11 (S715). At the monitoring center 10, it is determined whether or not the restoration operation may be started in the elevator based on the video data after the stop received by the external device 11. This determination may be made by, for example, a plurality of people who have viewed the video. When it is determined that the restoration operation may be started in the elevator, a start signal is transmitted from the external device 11.
　監視装置８では、Ｓ７０３でＮｏと判定された場合であっても、外部機器１１から開始信号を受信すると（Ｓ７１５のＹｅｓ）、通信部６２が第４モード信号を制御装置７及びカメラユニット１６に送信する（Ｓ７０４）。第４モード信号を受信した制御装置７及びカメラユニット１６では、図１５を用いて説明した動作と同様の動作が行われる。また、地震計１４が制御装置７に接続される場合は、図１６に示す動作フローは制御装置７で行われても良い。 In the monitoring device 8, even when No is determined in S703, when the start signal is received from the external device 11 (Yes in S715), the communication unit 62 sends the fourth mode signal to the control device 7 and the camera unit 16. Transmit (S704). The control device 7 and the camera unit 16 that have received the fourth mode signal perform the same operations as those described with reference to FIG. Further, when the seismograph 14 is connected to the control device 7, the operation flow shown in FIG. 16 may be performed by the control device 7.
　更に、カメラ２４によって撮影された映像を運転モードに応じて利用する他の例について説明する。図１７は、監視装置８の他の動作例を示すフローチャートである。 Further, another example of using the image captured by the camera 24 according to the operation mode will be described. FIG. 17 is a flowchart showing another operation example of the monitoring device 8.
　例えば、制御装置７の運転制御部５１で自動運転が行われている間、監視装置８では、保守モードに設定されたか否かが判定される（Ｓ８０１）。例えば、かご１の操作盤３４に、運転モードを保守モードに設定するためのスイッチ３４ａが備えられる。スイッチ３４ａは、運転モードを保守モードに設定する手段の一例である。スイッチ３４ａと同じ機能を有するスイッチ等の手段が、他の場所に設置されていても良い。例えば、スイッチ３４ａに対して特定の操作が行われることにより、運転モードが保守モードに設定される。スイッチ３４ａによって保守モードに設定されると（Ｓ８０１のＹｅｓ）、人検出部６４は、昇降路３に人がいるか否かを判定する（Ｓ８０２）。 For example, while the operation control unit 51 of the control device 7 is performing automatic operation, the monitoring device 8 determines whether or not the maintenance mode is set (S801). For example, the operation panel 34 of the car 1 is provided with a switch 34a for setting the operation mode to the maintenance mode. The switch 34a is an example of means for setting the operation mode to the maintenance mode. Means such as a switch having the same function as the switch 34a may be installed in another place. For example, the operation mode is set to the maintenance mode by performing a specific operation on the switch 34a. When the maintenance mode is set by the switch 34a (Yes in S801), the person detection unit 64 determines whether or not there is a person in the hoistway 3 (S802).
　また、カメラユニット１６では、エレベーターで自動運転が行われていれば、選択部４１が赤外線ランプ２３を選択する（Ｓ１０１）。例えば、自動運転が行われている間、カメラ２４によって撮影された赤外線映像が記憶部４０に保存される。 Further, in the camera unit 16, if the elevator is automatically operated, the selection unit 41 selects the infrared lamp 23 (S101). For example, the infrared image captured by the camera 24 is stored in the storage unit 40 while the automatic operation is being performed.
　選択部４１が赤外線ランプ２３を選択している時に運転モードが保守モードに設定されると、切替条件が成立したことを条件判定部４５が判定する（Ｓ１０７のＹｅｓ）。これにより、選択部４１は、Ｓ１０８で可視光ランプ２２を選択する。例えば、運転モードが保守モードに設定されると、Ｓ１０９でＹｅｓと判定され、Ｓ１１１でＹｅｓと判定される。Ｓ１１２において、通信部４４は、カメラ２４による映像データを監視装置８に送信する。 If the operation mode is set to the maintenance mode while the selection unit 41 is selecting the infrared lamp 23, the condition determination unit 45 determines that the switching condition is satisfied (Yes in S107). As a result, the selection unit 41 selects the visible light lamp 22 in S108. For example, when the operation mode is set to the maintenance mode, S109 determines Yes, and S111 determines Yes. In S112, the communication unit 44 transmits the video data obtained by the camera 24 to the monitoring device 8.
　通信部４４から送信された映像データは、監視装置８において通信部６２によって受信される。人検出部６４は、通信部６２が受信した映像データに基づいて、昇降路３に人がいることを検出する（Ｓ８０２のＹｅｓ）。例えば、人検出部６４は、カメラユニット１６から受信した映像データに基づいて、昇降路３のピット３ａに人がいることを検出する。人検出部６４は、カメラユニット１７から受信した映像データに基づいて、かご１の上に人がいることを検出する。 The video data transmitted from the communication unit 44 is received by the communication unit 62 in the monitoring device 8. The person detection unit 64 detects that there is a person in the hoistway 3 based on the video data received by the communication unit 62 (Yes in S802). For example, the person detection unit 64 detects that a person is in the pit 3a of the hoistway 3 based on the video data received from the camera unit 16. The person detection unit 64 detects that there is a person on the car 1 based on the video data received from the camera unit 17.
　昇降路３に人がいることが人検出部６４によって検出されると、禁止部６５は、自動運転が行われることを禁止する（Ｓ８０３）。例えば、自動運転でのかご１の可動範囲は、保守モードにおけるかご１の可動範囲より広い。図１７に示す例であれば、昇降路３に人がいるにも関わらず、自動運転が開始されてしまうことを防止できる。 When the person detection unit 64 detects that there is a person on the hoistway 3, the prohibition unit 65 prohibits the automatic operation from being performed (S803). For example, the movable range of the car 1 in the automatic operation is wider than the movable range of the car 1 in the maintenance mode. In the example shown in FIG. 17, it is possible to prevent the automatic operation from being started even though there is a person on the hoistway 3.
　昇降路３に人がいることが人検出部６４によって検出された場合は、昇降路３にいる人に向けて、かご１の位置に応じた報知を行っても良い。例えば、昇降路３に人がいることが人検出部６４によって検出されると、放射制御部４２は、かご１の位置に応じて、可視光ランプ２２からの可視光の放射モードを変更する。例えば、放射制御部４２は、かご１がピット３ａに近づくに従って、点滅速度が速くなるように可視光ランプ２２を制御する。放射制御部４２は、かご１の位置に応じて、可視光ランプ２２から放射される光の色を変化させても良い。 When the person detection unit 64 detects that there is a person in the hoistway 3, the person in the hoistway 3 may be notified according to the position of the car 1. For example, when the person detection unit 64 detects that there is a person in the hoistway 3, the radiation control unit 42 changes the visible light emission mode from the visible light lamp 22 according to the position of the car 1. For example, the radiation control unit 42 controls the visible light lamp 22 so that the blinking speed increases as the car 1 approaches the pit 3a. The radiation control unit 42 may change the color of the light emitted from the visible light lamp 22 according to the position of the car 1.
　他の例として、昇降路３に人がいることが人検出部６４によって検出されると、音制御部４３は、かご１の位置に応じて、スピーカ２６から音を出力させても良い。例えば、音制御部４３は、かご１がある高さより低い位置に配置されると、スピーカ２６から警告音を発生させる。これにより、昇降路３にいる人に注意を促すことができる。 As another example, when the person detection unit 64 detects that there is a person in the hoistway 3, the sound control unit 43 may output sound from the speaker 26 according to the position of the car 1. For example, when the sound control unit 43 is arranged at a position lower than a certain height of the car 1, the speaker 26 generates a warning sound. As a result, the person in the hoistway 3 can be alerted.
　本実施の形態に示す例では、カメラユニット１６がソケット１８を介してかご１に固定される。また、カメラユニット１７は、ソケット１９を介してかご１に固定される。カメラユニット１６或いは１７を用いることによって既設の設備或いは設計を利用することが可能となり、カメラ２４を設置する費用と手間とを低減できる。 In the example shown in this embodiment, the camera unit 16 is fixed to the car 1 via the socket 18. Further, the camera unit 17 is fixed to the car 1 via the socket 19. By using the camera unit 16 or 17, it becomes possible to use the existing equipment or design, and the cost and labor for installing the camera 24 can be reduced.
　以下に、既設のエレベーターを改修して、上記エレベーター装置を実現する例について説明する。図１８は、エレベーターの改修方法を示すフローチャートである。改修前のエレベーター装置には、例えば昇降路３の内部を照らすための第１電球がソケット１８を介してかご１に設けられている。同様に、昇降路３の内部を照らすための第２電球がソケット１９を介してかご１に設けられている。 The following is an example of modifying an existing elevator to realize the above elevator device. FIG. 18 is a flowchart showing a method of repairing the elevator. In the elevator device before the repair, for example, a first light bulb for illuminating the inside of the hoistway 3 is provided in the car 1 via the socket 18. Similarly, a second light bulb for illuminating the inside of the hoistway 3 is provided in the car 1 via the socket 19.
　先ず、保守員は、ソケット１８から第１電球を外す。また、ソケット１９から第２電球を外す（Ｓ９０１）。次に、第１電球を外したソケット１８に、カメラユニット１６を取り付ける。上述したように、カメラユニット１６には口金２１が備えられる。口金２１をソケット１８にねじ込むことにより、カメラユニット１６をソケット１８に固定することができる。保守員は、同様に、第２電球を外したソケット１９にカメラユニット１７を取り付ける（Ｓ９０２）。 First, the maintenance staff removes the first light bulb from the socket 18. Also, the second light bulb is removed from the socket 19 (S901). Next, the camera unit 16 is attached to the socket 18 from which the first light bulb has been removed. As described above, the camera unit 16 is provided with a base 21. The camera unit 16 can be fixed to the socket 18 by screwing the base 21 into the socket 18. Similarly, the maintenance staff attaches the camera unit 17 to the socket 19 from which the second light bulb has been removed (S902).
　Ｓ９０３からＳ９０６に示す手順は、必要に応じて採用される。例えば、カメラ２４によって昇降路３の内部の映像を常に撮影する場合は、カメラユニット１６にソケット１８を介して電力が常時供給されるように設定が変更される（Ｓ９０３）。カメラユニット１７に対しても同様の設定変更が行われる。 The procedure shown in S903 to S906 is adopted as necessary. For example, when the camera 24 constantly captures an image of the inside of the hoistway 3, the setting is changed so that power is always supplied to the camera unit 16 via the socket 18 (S903). Similar setting changes are made to the camera unit 17.
　カメラユニット１６が映像データをアクセスポイント１２を介して携帯端末１３等に送信する場合は、通信部４４とアクセスポイント１２との通信を確立する工程が更に備えられる（Ｓ９０４）。カメラユニット１７に対しても同様の処理が行われる。 When the camera unit 16 transmits video data to the mobile terminal 13 or the like via the access point 12, a step of establishing communication between the communication unit 44 and the access point 12 is further provided (S904). The same processing is performed on the camera unit 17.
　かご１に金属製の前垂れが備えられている場合は、金属製の既設の前垂れを透光性を有する前垂れ３８に交換する工程を更に備えても良い（Ｓ９０５）。これにより、前垂れ３８に覆われている部分の映像をカメラ２４によって撮影することができる。 When the car 1 is provided with a metal front hang, a step of replacing the existing metal front hang with a translucent front hang 38 may be further provided (S905). As a result, the image of the portion covered by the front hanging 38 can be captured by the camera 24.
　保守員の携帯端末１３に、信号生成部７３を新たに追加する工程を更に備えても良い（Ｓ９０６）。これにより、携帯端末１３からの操作によって選択部４１に可視光ランプ２２を選択させ、カメラ２４による可視光映像を表示器７１に表示させることができる。同様に、外部機器１１に、信号生成部８３を新たに追加する工程を更に備えても良い（Ｓ９０６）。これにより、外部機器１１からの操作によって選択部４１に可視光ランプ２２を選択させ、カメラ２４による可視光映像を表示器８１に表示させることができる。 A process of newly adding a signal generation unit 73 to the maintenance staff's mobile terminal 13 may be further provided (S906). As a result, the selection unit 41 can select the visible light lamp 22 by the operation from the mobile terminal 13, and the visible light image by the camera 24 can be displayed on the display 71. Similarly, the external device 11 may be further provided with a step of newly adding the signal generation unit 83 (S906). As a result, the selection unit 41 can select the visible light lamp 22 by the operation from the external device 11, and the visible light image by the camera 24 can be displayed on the display 81.
