　以下に、図３から図７も参照し、利用者Ｄが鍵、書類、或いはお金といった物を昇降路１２に落としてしまった時に行われる動作について詳しく説明する。 Below, with reference also to FIGS. 3 to 7, a detailed description will be given of the operations performed when User D drops an object such as a key, document, or money into the hoistway 12. FIG.
　昇降路１２に物を落とした利用者Ｄは、コールセンター４０に連絡する。例えば、乗場６に設けられた案内板にコールセンター４０の電話番号が記載されている。利用者Ｄは、その記載を見てコールセンター４０に電話を掛ける。コールセンター４０では、オペレーターＢが電話を受ける。利用者Ｄは、昇降路１２に物を落としてしまったこととエレベーター装置１の識別番号とをオペレーターＢに伝える。当該識別番号は、エレベーター装置１を特定するための番号である。識別番号は、コールセンター４０の電話番号とともに案内板に記載されている。 User D, who dropped an object on the hoistway 12, contacts the call center 40. For example, the telephone number of the call center 40 is written on the information board provided at the hall 6 . User D calls the call center 40 after seeing the description. At call center 40, operator B receives the call. The user D informs the operator B that the object has been dropped on the hoistway 12 and the identification number of the elevator device 1. - 特許庁The identification number is a number for specifying the elevator device 1 . The identification number is written on the information board together with the telephone number of the call center 40 .
　図３及び図４は、端末装置４の動作例を示すフローチャートである。図３及び図４は、一連の動作を示す。端末装置４では、識別番号が入力されたか否かが判定される（Ｓ１０１）。利用者Ｄから連絡を受けたオペレーターＢが入力装置４２を用いてエレベーター装置１の識別番号を入力すると、Ｓ１０１でＹｅｓと判定される。Ｓ１０１でＹｅｓと判定されると、表示制御部４３は、エレベーター装置１に関する情報を表示器４１に表示する（Ｓ１０２）。 3 and 4 are flow charts showing an operation example of the terminal device 4. FIG. 3 and 4 show a sequence of operations. The terminal device 4 determines whether or not an identification number has been input (S101). When the operator B, who has been contacted by the user D, uses the input device 42 to input the identification number of the elevator device 1, it is determined as Yes in S101. When it is determined as Yes in S101, the display control unit 43 displays information about the elevator device 1 on the display 41 (S102).
　次に、端末装置４では、特定の開始条件が成立したか否かが判定される（Ｓ１０３）。当該開始条件は、昇降路１２への落とし物を探すための動作を開始する条件である。開始条件は、予め設定される。例えば、Ｓ１０２において、表示器４１に開始釦が表示される。オペレーターＢが入力装置４２を用いて当該開始釦を押すと、開始条件が成立する。オペレーターＢは、利用者Ｄから昇降路１２への落とし物の連絡を受けると、この開始釦を押す。これにより、Ｓ１０３でＹｅｓと判定される。 Next, the terminal device 4 determines whether or not a specific start condition is satisfied (S103). The start condition is a condition for starting an operation for searching for an object dropped on the hoistway 12 . A start condition is set in advance. For example, a start button is displayed on the display 41 in S102. When the operator B presses the start button using the input device 42, the start condition is satisfied. The operator B presses the start button when receiving a message from the user D about the lost item on the hoistway 12 . As a result, a determination of Yes is made in S103.
　画像要求部４４は、昇降路１２への落とし物の連絡を受けた際にエレベーター装置１に対して画像要求Ｒ１を行う機能を有する。画像要求Ｒ１は、カメラ１８に昇降路１２の画像を撮影させるための要求である。Ｓ１０３でＹｅｓと判定されると、画像要求部４４は、サーバ２に画像要求Ｒ１を送信する（Ｓ１０４）。 The image requesting unit 44 has a function of making an image request R1 to the elevator device 1 upon receiving notification of an item lost in the hoistway 12 . The image request R1 is a request for causing the camera 18 to capture an image of the hoistway 12 . If determined as Yes in S103, the image requesting unit 44 transmits an image request R1 to the server 2 (S104).
　派遣要請部４５は、画像要求Ｒ１が行われる際にエレベーター装置１への保守員の派遣要請を行う機能を有する。Ｓ１０３でＹｅｓと判定されると、派遣要請部４５は、保守拠点３０に派遣要請を送信する（Ｓ１０５）。派遣要請には、昇降路１２への落とし物が発生したことを示す情報とエレベーター装置１の識別番号を示す情報とが含まれる。保守拠点３０では、当該派遣要請を受信すると、保守員Ａが携帯端末３を所持してエレベーター装置１の現場へと向かう。 The dispatch request unit 45 has a function of requesting dispatch of maintenance personnel to the elevator device 1 when the image request R1 is made. When determined as Yes in S103, the dispatch requesting unit 45 transmits a dispatch request to the maintenance base 30 (S105). The dispatch request includes information indicating that an object has been dropped on the hoistway 12 and information indicating the identification number of the elevator device 1 . At the maintenance base 30 , when the dispatch request is received, the maintenance worker A carries the portable terminal 3 and heads to the site of the elevator device 1 .
　図５は、サーバ２の動作例を示すフローチャートである。サーバ２では、コールセンター４０の端末装置４から画像要求Ｒ１を受信したか否かが判定される（Ｓ２０１）。Ｓ１０４で端末装置４から送信された画像要求Ｒ１を通信部２２が受信すると、Ｓ２０１でＹｅｓと判定される。Ｓ２０１でＹｅｓと判定されると、通信部２２は、受信した画像要求Ｒ１を監視装置１４に転送する（Ｓ２０２）。即ち、本実施の形態に示す例では、画像要求部４４は、サーバ２を介してエレベーター装置１に画像要求Ｒ１を行う。 FIG. 5 is a flowchart showing an operation example of the server 2. The server 2 determines whether or not the image request R1 has been received from the terminal device 4 of the call center 40 (S201). When the communication unit 22 receives the image request R1 transmitted from the terminal device 4 in S104, it is determined as Yes in S201. If determined as Yes in S201, the communication unit 22 transfers the received image request R1 to the monitoring device 14 (S202). That is, in the example shown in this embodiment, the image requesting unit 44 makes an image request R1 to the elevator device 1 via the server 2 .
　図６は、監視装置１４の動作例を示すフローチャートである。監視装置１４では、サーバ２から画像要求Ｒ１を受信したか否かが判定される（Ｓ３０１）。Ｓ２０２でサーバ２から送信された画像要求Ｒ１を通信部６２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 monitoring device 14. FIG. The monitoring device 14 determines whether or not the image request R1 has been received from the server 2 (S301). When the communication unit 62 receives the image request R1 transmitted from the server 2 in S202, a determination of Yes is made in S301.
　運転指令部６３は、監視装置１４が画像要求Ｒ１を受信すると、受信した画像要求Ｒ１に応じて制御装置１３に第１専用運転を行わせる。第１専用運転は、かご１１を特定の第１撮影位置に停止させるための運転である。第１撮影位置は予め設定される。一例として、第１撮影位置は最下階の乗場６である。例えば、運転指令部６３は、Ｓ３０１でＹｅｓと判定されると、運転指令Ｃ１を制御装置１３に送信する（Ｓ３０２）。 When the monitoring device 14 receives the image request R1, the operation command unit 63 causes the control device 13 to perform the first dedicated operation according to the received image request R1. The first dedicated operation is an operation for stopping the car 11 at a specific first photographing position. The first shooting position is set in advance. As an example, the first shooting position is the landing 6 on the lowest floor. For example, when determined as Yes in S301, the operation command unit 63 transmits the operation command C1 to the control device 13 (S302).
　また、監視装置１４が画像要求Ｒ１を受信すると（Ｓ３０１のＹｅｓ）、カメラ制御部６４は、受信した画像要求Ｒ１に応じてカメラ１８による撮影を開始させる（Ｓ３０３）。カメラ１８による撮影が開始される際にランプ１９が点灯する。 Also, when the monitoring device 14 receives the image request R1 (Yes in S301), the camera control unit 64 causes the camera 18 to start photographing in accordance with the received image request R1 (S303). The lamp 19 lights up when the camera 18 starts photographing.
　図７は、制御装置１３の動作例を示すフローチャートである。制御装置１３では、監視装置１４から運転指令Ｃ１を受信したか否かが判定される（Ｓ４０１）。Ｓ３０２で監視装置１４から送信された運転指令Ｃ１を制御装置１３が受信すると、Ｓ４０１でＹｅｓと判定される。 FIG. 7 is a flowchart showing an operation example of the control device 13. FIG. In the control device 13, it is determined whether or not the operation command C1 has been received from the monitoring device 14 (S401). When the control device 13 receives the operation command C1 transmitted from the monitoring device 14 in S302, a determination of Yes is made in S401.
　Ｓ４０１でＹｅｓと判定されると、運転制御部５１は、第１専用運転を行う（Ｓ４０２）。例えば、運転制御部５１は、Ｓ４０１でＹｅｓと判定されると、かご１１を第１撮影位置に向けて移動させる。運転制御部５１は、かご１１が第１撮影位置に到着すると、かご１１を第１撮影位置に停止させる。 When determined as Yes in S401, the operation control unit 51 performs the first dedicated operation (S402). For example, when determined as Yes in S401, the operation control unit 51 moves the car 11 toward the first photographing position. When the car 11 reaches the first photographing position, the operation control unit 51 stops the car 11 at the first photographing position.
　図６に示すように、監視装置１４では、Ｓ３０２で運転指令Ｃ１が送信されると、かご１１が第１撮影位置に停止したか否かが判定される（Ｓ３０４）。Ｓ４０２に示す第１専用運転においてかご１１が第１撮影位置に停止すると、Ｓ３０４でＹｅｓと判定される。なお、Ｓ３０３に示す処理は、Ｓ３０４の後に行われても良い。即ち、カメラ１８による撮影は、Ｓ３０４でＹｅｓと判定されることによって開始されても良い。 As shown in FIG. 6, when the operation command C1 is transmitted in S302, the monitoring device 14 determines whether or not the car 11 has stopped at the first imaging position (S304). When the car 11 stops at the first imaging position in the first dedicated operation shown in S402, the determination in S304 is Yes. Note that the processing shown in S303 may be performed after S304. That is, the photographing by the camera 18 may be started by determining Yes in S304.
　Ｓ３０４でＹｅｓと判定されると、画像取得部６５は、カメラ１８によって撮影された画像を取得する（Ｓ３０５）。即ち、Ｓ３０５では、第１専用運転においてかご１１が第１撮影位置に停止している時にカメラ１８によって撮影された昇降路１２の画像が、画像取得部６５によって取得される。以下においては、Ｓ３０５で画像取得部６５が取得した画像を第１画像ともいう。第１画像には、昇降路１２のピットを上方から撮影した画像が含まれる。 When it is determined as Yes in S304, the image acquisition unit 65 acquires the image captured by the camera 18 (S305). That is, in S305, the image acquiring unit 65 acquires the image of the hoistway 12 captured by the camera 18 while the car 11 is stopped at the first capturing position in the first dedicated operation. Hereinafter, the image acquired by the image acquiring unit 65 in S305 is also referred to as the first image. The first image includes an image of the pit of the hoistway 12 taken from above.
　通信部６２は、画像取得部６５によって取得された第１画像をサーバ２に対して送信する（Ｓ３０６）。 The communication unit 62 transmits the first image acquired by the image acquisition unit 65 to the server 2 (S306).
　図５に示すように、サーバ２では、Ｓ２０２で画像要求Ｒ１が送信されると、監視装置１４から第１画像を受信したか否かが判定される（Ｓ２０３）。Ｓ３０６で監視装置１４から送信された第１画像を通信部２２が受信すると、Ｓ２０３でＹｅｓと判定される。Ｓ２０３で監視装置１４から受信した第１画像は、記憶部２１に記憶される（Ｓ２０４）。また、Ｓ２０３でＹｅｓと判定されると、通信部２２は、画像要求Ｒ１の応答として、第１画像が取得されたことを示す第１取得情報を端末装置４に送信する（Ｓ２０５）。 As shown in FIG. 5, when the image request R1 is transmitted in S202, the server 2 determines whether or not the first image has been received from the monitoring device 14 (S203). When the communication unit 22 receives the first image transmitted from the monitoring device 14 in S306, a determination of Yes is made in S203. The first image received from the monitoring device 14 in S203 is stored in the storage unit 21 (S204). Further, when determined as Yes in S203, the communication unit 22 transmits first acquisition information indicating that the first image has been acquired to the terminal device 4 as a response to the image request R1 (S205).
　図３に示すように、端末装置４では、Ｓ１０４で画像要求Ｒ１が送信されると、その応答としてサーバ２から第１取得情報を受信したか否かが判定される（Ｓ１０６）。Ｓ２０５でサーバ２から送信された第１取得情報を端末装置４が受信すると、Ｓ１０６でＹｅｓと判定される。Ｓ１０６でＹｅｓと判定されると、表示制御部４３は、サーバ２の記憶部２１に保存された第１画像を表示器４１に表示する（Ｓ１０７）。 As shown in FIG. 3, in the terminal device 4, when the image request R1 is transmitted in S104, it is determined whether or not the first acquisition information has been received from the server 2 as a response (S106). When the terminal device 4 receives the first acquisition information transmitted from the server 2 in S205, it is determined as Yes in S106. If determined as Yes in S106, the display control unit 43 displays the first image saved in the storage unit 21 of the server 2 on the display device 41 (S107).
　表示器４１に第１画像が表示されると、端末装置４では、特定の第１条件が成立したか否かが判定される（Ｓ１０８）。Ｓ１０８でＮｏと判定されると、端末装置４では、特定の第２条件が成立したか否かが判定される（Ｓ１０９）。第１条件は、オペレーターＢが第１画像から落とし物を見つけた場合に行われる動作を開始するための条件である。第２条件は、オペレーターＢが第１画像からは落とし物を見つけることができなかった場合に行われる動作を開始するための条件である。 When the first image is displayed on the display 41, the terminal device 4 determines whether or not a specific first condition is satisfied (S108). If it is determined as No in S108, the terminal device 4 determines whether or not a specific second condition is satisfied (S109). The first condition is a condition for starting an action to be performed when operator B finds a lost item in the first image. The second condition is a condition for starting an action to be performed when operator B cannot find the lost item from the first image.
　オペレーターＢは、表示器４１に表示された第１画像、即ち昇降路１２のピットが写された画像を見て、落とし物を探す。一例として、オペレーターＢは、第１画像から落とし物を見つけることができれば、表示器４１に表示された確認釦を押す。これにより、第１条件が成立する（Ｓ１０８のＹｅｓ）。また、オペレーターＢは、第１画像からは落とし物を見つけることができなければ、表示器４１に表示された画像取得釦を押す。これにより、第２条件が成立する（Ｓ１０９のＹｅｓ）。なお、オペレーターＢが入力装置４２を用いて行う他の操作によって第１条件或いは第２条件が成立しても良い。 Operator B looks at the first image displayed on the display 41, that is, the image showing the pit of the hoistway 12, and searches for the lost item. As an example, if the operator B can find the lost item from the first image, the operator B presses the confirmation button displayed on the display 41 . Thereby, the first condition is satisfied (Yes in S108). Also, if the operator B cannot find the lost item from the first image, he presses the image acquisition button displayed on the display 41 . Thereby, the second condition is established (Yes in S109). Note that the first condition or the second condition may be satisfied by another operation performed by the operator B using the input device 42 .
　Ｓ１０８でＹｅｓと判定されると、画像提供部４６は、サーバ２の記憶部２１に記憶された第１画像をかご１１に提供する（Ｓ１１０）。これにより、サーバ２の記憶部２１に記憶された第１画像が表示器１６に表示される。即ち、確認釦が押されることにより、第１画像がサーバ２から監視装置１４を介して制御装置１３に提供される。表示制御部５２は、サーバ２から受信した第１画像を表示器１６に表示する。 When determined as Yes in S108, the image providing unit 46 provides the first image stored in the storage unit 21 of the server 2 to the car 11 (S110). Thereby, the first image stored in the storage unit 21 of the server 2 is displayed on the display device 16 . That is, by pressing the confirmation button, the first image is provided from the server 2 to the control device 13 via the monitoring device 14 . The display control unit 52 displays the first image received from the server 2 on the display device 16 .
　オペレーターＢは、確認釦を押すと、表示器１６を見てもらうために利用者Ｄに連絡する。そして、オペレーターＢは、自分が見つけた落とし物が利用者Ｄが落とした物と一致するかを利用者Ｄに尋ねる。オペレーターＢが見つけた落とし物が利用者Ｄが落とした物と一致すれば、オペレーターＢは、表示器４１に表示された通知釦を押す。 When operator B presses the confirmation button, he contacts user D to have him look at the display 16. Then, operator B asks user D whether the lost item he found matches the item user D dropped. If the dropped item found by the operator B matches the item dropped by the user D, the operator B presses the notification button displayed on the display 41 .
　当該通知釦が押されると、画像提供部４６は、サーバ２の記憶部２１に記憶された第１画像を保守員Ａに提供する（Ｓ１１１）。これにより、派遣要請を受けて派遣された保守員Ａの携帯端末３の表示器３１に第１画像が表示される。この時、第１画像は、サーバ２から携帯端末３に直接送信されても良い。第１画像は、端末装置４を介して携帯端末３に送信されても良い。 When the notification button is pressed, the image providing unit 46 provides maintenance worker A with the first image stored in the storage unit 21 of the server 2 (S111). As a result, the first image is displayed on the display 31 of the portable terminal 3 of the maintenance worker A dispatched in response to the dispatch request. At this time, the first image may be directly transmitted from the server 2 to the mobile terminal 3 . The first image may be transmitted to the mobile terminal 3 via the terminal device 4 .
　一方、Ｓ１０９でＹｅｓと判定されると、画像要求部４４は、サーバ２に画像要求Ｒ２を送信する（Ｓ１１２）。画像要求Ｒ２は、画像要求Ｒ１と同様に、カメラ１８に昇降路１２の画像を撮影させるための要求である。画像要求Ｒ２は、昇降路１２のピットの拡大画像を要求する。 On the other hand, if determined as Yes in S109, the image requesting unit 44 transmits an image request R2 to the server 2 (S112). The image request R2 is a request for causing the camera 18 to capture an image of the hoistway 12, similar to the image request R1. The image request R2 requests an enlarged image of the pit of the hoistway 12 .
　図５に示すように、サーバ２では、Ｓ２０５で第１取得情報が送信されると、端末装置４から画像要求Ｒ２を受信したか否かが判定される（Ｓ２０６）。Ｓ１１２で端末装置４から送信された画像要求Ｒ２を通信部２２が受信すると、Ｓ２０６でＹｅｓと判定される。Ｓ２０６でＹｅｓと判定されると、通信部２２は、受信した画像要求Ｒ２を監視装置１４に転送する（Ｓ２０７）。即ち、本実施の形態に示す例では、画像要求部４４は、サーバ２を介してエレベーター装置１に画像要求Ｒ２を行う。 As shown in FIG. 5, in the server 2, when the first acquisition information is transmitted in S205, it is determined whether or not the image request R2 has been received from the terminal device 4 (S206). When the communication unit 22 receives the image request R2 transmitted from the terminal device 4 in S112, a determination of Yes is made in S206. If determined as Yes in S206, the communication unit 22 transfers the received image request R2 to the monitoring device 14 (S207). That is, in the example shown in this embodiment, the image requesting unit 44 makes an image request R2 to the elevator device 1 via the server 2 .
　図６に示すように、監視装置１４では、Ｓ３０６で第１画像が送信されると、サーバ２から画像要求Ｒ２を受信したか否かが判定される（Ｓ３０７）。Ｓ２０７でサーバ２から送信された画像要求Ｒ２を通信部６２が受信すると、Ｓ３０７でＹｅｓと判定される。 As shown in FIG. 6, in the monitoring device 14, when the first image is transmitted in S306, it is determined whether or not the image request R2 has been received from the server 2 (S307). When the communication unit 62 receives the image request R2 transmitted from the server 2 in S207, a determination of Yes is made in S307.
　運転指令部６３は、監視装置１４が画像要求Ｒ２を受信すると、受信した画像要求Ｒ２に応じて制御装置１３に第２専用運転を行わせる。第２専用運転は、かご１１を第１撮影位置より下方の特定の第２撮影位置に停止させるための運転である。第２撮影位置は予め設定される。一例として、第２撮影位置は、かご１１が移動できる最も下方の位置である。例えば、昇降路１２に、かご１１の下方への移動を規制するためのスイッチが設けられる。第２撮影位置は、当該スイッチが動作する位置である。Ｓ３０７でＹｅｓと判定されると、運転指令部６３は、運転指令Ｃ２を制御装置１３に送信する（Ｓ３０８）。 When the monitoring device 14 receives the image request R2, the operation command unit 63 causes the control device 13 to perform the second dedicated operation according to the received image request R2. The second exclusive operation is an operation for stopping the car 11 at a specific second photographing position below the first photographing position. The second shooting position is set in advance. As an example, the second photographing position is the lowest position to which the car 11 can move. For example, the hoistway 12 is provided with a switch for restricting the downward movement of the car 11 . The second shooting position is the position where the switch operates. When determined as Yes in S307, the operation command unit 63 transmits the operation command C2 to the control device 13 (S308).
　図７に示すように、制御装置１３では、第１専用運転が行われた後、監視装置１４から運転指令Ｃ２を受信したか否かが判定される（Ｓ４０３）。Ｓ３０８で監視装置１４から送信された運転指令Ｃ２を制御装置１３が受信すると、Ｓ４０３でＹｅｓと判定される。 As shown in FIG. 7, in the control device 13, after the first dedicated operation is performed, it is determined whether or not the operation command C2 has been received from the monitoring device 14 (S403). When the control device 13 receives the operation command C2 transmitted from the monitoring device 14 in S308, a determination of Yes is made in S403.
　Ｓ４０３でＹｅｓと判定されると、運転制御部５１は、第２専用運転を行う（Ｓ４０４）。例えば、運転制御部５１は、Ｓ４０３でＹｅｓと判定されると、かご１１を最下階の乗場６から下方に移動させる。運転制御部５１は、かご１１が第２撮影位置に到着すると、かご１１を第２撮影位置に停止させる。なお、運転制御部５１は、第２専用運転において、ランプ１７を消灯させても良い。運転制御部５１は、かご１１を第２撮影位置に一定時間だけ停止させると、かご１１を上方に移動させて、最下階の乗場６に移動させる。 When determined as Yes in S403, the operation control unit 51 performs the second exclusive operation (S404). For example, when it is determined as Yes in S403, the operation control unit 51 moves the car 11 downward from the hall 6 on the lowest floor. When the car 11 reaches the second photographing position, the operation control unit 51 stops the car 11 at the second photographing position. Note that the operation control unit 51 may turn off the lamp 17 in the second dedicated operation. After stopping the car 11 at the second photographing position for a certain period of time, the operation control unit 51 moves the car 11 upward to the landing 6 on the lowest floor.
　図６に示すように、監視装置１４では、Ｓ３０８で運転指令Ｃ２が送信されると、かご１１が第２撮影位置に停止したか否かが判定される（Ｓ３０９）。Ｓ４０４に示す第２専用運転においてかご１１が第２撮影位置に停止すると、Ｓ３０９でＹｅｓと判定される。なお、第２専用運転が行われている間も、ランプ１９は点灯し、カメラ１８による撮影が行われる。 As shown in FIG. 6, when the operation command C2 is transmitted in S308, the monitoring device 14 determines whether or not the car 11 has stopped at the second imaging position (S309). When the car 11 stops at the second photographing position in the second dedicated operation shown in S404, the determination in S309 is Yes. Note that the lamp 19 is lit and the camera 18 takes pictures even while the second exclusive operation is being performed.
　Ｓ３０９でＹｅｓと判定されると、画像取得部６５は、カメラ１８によって撮影された画像を取得する（Ｓ３１０）。即ち、Ｓ３１０では、第２専用運転においてかご１１が第２撮影位置に停止している時にカメラ１８によって撮影された昇降路１２の画像が、画像取得部６５によって取得される。以下においては、Ｓ３１０で画像取得部６５が取得した画像を第２画像ともいう。第２画像には、昇降路１２のピットを上方から撮影した画像が含まれる。第２画像には、ピットの拡大画像が含まれる。 When determined as Yes in S309, the image acquisition unit 65 acquires the image captured by the camera 18 (S310). That is, in S310, the image acquiring unit 65 acquires the image of the hoistway 12 captured by the camera 18 while the car 11 is stopped at the second capturing position in the second dedicated operation. Hereinafter, the image acquired by the image acquiring unit 65 in S310 is also referred to as a second image. The second image includes an image of the pit of the hoistway 12 photographed from above. The second image contains an enlarged image of the pit.
　通信部６２は、画像取得部６５によって取得された第２画像をサーバ２に対して送信する（Ｓ３１１）。 The communication unit 62 transmits the second image acquired by the image acquisition unit 65 to the server 2 (S311).
　図５に示すように、サーバ２では、Ｓ２０７で画像要求Ｒ２が送信されると、監視装置１４から第２画像を受信したか否かが判定される（Ｓ２０８）。Ｓ３１１で監視装置１４から送信された第２画像を通信部２２が受信すると、Ｓ２０８でＹｅｓと判定される。Ｓ２０８で監視装置１４から受信した第２画像は、記憶部２１に記憶される（Ｓ２０９）。また、Ｓ２０８でＹｅｓと判定されると、通信部２２は、画像要求Ｒ２の応答として、第２画像が取得されたことを示す第２取得情報を端末装置４に送信する（Ｓ２１０）。 As shown in FIG. 5, when the image request R2 is transmitted in S207, the server 2 determines whether or not the second image has been received from the monitoring device 14 (S208). When the communication unit 22 receives the second image transmitted from the monitoring device 14 in S311, a determination of Yes is made in S208. The second image received from the monitoring device 14 in S208 is stored in the storage unit 21 (S209). Further, when it is determined as Yes in S208, the communication unit 22 transmits second acquisition information indicating that the second image has been acquired to the terminal device 4 as a response to the image request R2 (S210).
　図４に示すように、端末装置４では、Ｓ１１２で画像要求Ｒ２が送信されると、その応答としてサーバ２から第２取得情報を受信したか否かが判定される（Ｓ１１３）。Ｓ２１０でサーバ２から送信された第２取得情報を端末装置４が受信すると、Ｓ１１３でＹｅｓと判定される。Ｓ１１３でＹｅｓと判定されると、表示制御部４３は、サーバ２の記憶部２１に保存された第２画像を表示器４１に表示する（Ｓ１１４）。 As shown in FIG. 4, in the terminal device 4, when the image request R2 is transmitted in S112, it is determined whether or not the second acquisition information has been received from the server 2 as a response (S113). When the terminal device 4 receives the second acquired information transmitted from the server 2 in S210, it is determined as Yes in S113. When determined as Yes in S113, the display control unit 43 displays the second image stored in the storage unit 21 of the server 2 on the display device 41 (S114).
　表示器４１に第２画像が表示されると、端末装置４では、特定の第３条件が成立したか否かが判定される（Ｓ１１５）。第３条件は、オペレーターＢが第２画像から落とし物を見つけた場合に行われる動作を開始するための条件である。 When the second image is displayed on the display 41, the terminal device 4 determines whether or not a specific third condition is satisfied (S115). The third condition is a condition for starting an action to be performed when operator B finds a lost item in the second image.
　オペレーターＢは、表示器４１に表示された第２画像、即ち昇降路１２のピットの拡大画像を見て、落とし物を探す。一例として、オペレーターＢは、第２画像から落とし物を見つけることができれば、表示器４１に表示された確認釦を押す。これにより、第３条件が成立する（Ｓ１１５のＹｅｓ）。なお、オペレーターＢが入力装置４２を用いて行う他の操作によって第２条件が成立しても良い。 Operator B looks at the second image displayed on the display 41, that is, the enlarged image of the pit in the hoistway 12, and searches for the lost item. As an example, if the operator B can find the lost item from the second image, the operator B presses the confirmation button displayed on the display 41 . Thereby, the third condition is established (Yes in S115). Note that the second condition may be satisfied by another operation performed by the operator B using the input device 42 .
　Ｓ１１５でＹｅｓと判定された後のＳ１１６に示す処理は、図３のＳ１１０に示す処理と同様である。また、Ｓ１１７に示す処理は、図３のＳ１１１に示す処理と同様である。Ｓ１１５でＹｅｓと判定されると、画像提供部４６は、サーバ２の記憶部２１に記憶された第２画像をかご１１に提供する（Ｓ１１６）。これにより、サーバ２の記憶部２１に記憶された第２画像が表示器１６に表示される。 The processing shown in S116 after it is determined as Yes in S115 is the same as the processing shown in S110 of FIG. Also, the process shown in S117 is the same as the process shown in S111 of FIG. When it is determined as Yes in S115, the image providing unit 46 provides the second image stored in the storage unit 21 of the server 2 to the car 11 (S116). Thereby, the second image stored in the storage unit 21 of the server 2 is displayed on the display device 16 .
　その後、オペレーターＢは、自分が見つけた落とし物が利用者Ｄが落とした物と一致するかを利用者Ｄに尋ねる。オペレーターＢが見つけた落とし物が利用者Ｄが落とした物と一致すれば、オペレーターＢは、表示器４１に表示された通知釦を押す。 After that, operator B asks user D if the lost item he found matches the item user D dropped. If the dropped item found by the operator B matches the item dropped by the user D, the operator B presses the notification button displayed on the display 41 .
　当該通知釦が押されると、画像提供部４６は、サーバ２の記憶部２１に記憶された第２画像を保守員Ａに提供する（Ｓ１１７）。これにより、派遣要請を受けて派遣された保守員Ａの携帯端末３の表示器３１に第２画像が表示される。 When the notification button is pressed, the image providing unit 46 provides maintenance worker A with the second image stored in the storage unit 21 of the server 2 (S117). As a result, the second image is displayed on the display 31 of the portable terminal 3 of the maintenance worker A dispatched in response to the dispatch request.
　本実施の形態に示す例では、派遣要請を受けてエレベーター装置１の現場に向かっている保守員Ａの携帯端末３に、落とし物が写った第１画像或いは第２画像が送られる。保守員Ａは、携帯端末３に送られてきた第１画像或いは第２画像から、現場に到着する前に、落とし物の外観と落とし物の位置とを把握することができる。このため、本実施の形態に示す例であれば、保守員Ａが昇降路１２への落とし物を見つけ出すまでの時間を短縮することができる。また、保守員Ａが落とし物を拾うためには、エレベーター装置１のサービスを停止しなければならない。本実施の形態に示す例であれば、サービスを停止する時間を短くすることもできる。 In the example shown in this embodiment, the first image or the second image showing the lost item is sent to the mobile terminal 3 of the maintenance worker A who is heading to the site of the elevator device 1 in response to the dispatch request. From the first image or the second image sent to the portable terminal 3, the maintenance worker A can grasp the appearance of the lost item and the position of the lost item before arriving at the site. Therefore, in the example shown in the present embodiment, it is possible to reduce the time required for maintenance personnel A to find an object dropped on the hoistway 12 . Further, in order for the maintenance worker A to pick up the lost item, the service of the elevator device 1 must be stopped. In the example shown in this embodiment, it is possible to shorten the time during which the service is stopped.
　本実施の形態では、Ｓ１１１に示す処理が行われる前にＳ１１０に示す処理が行われる例について説明した。他の例として、Ｓ１１０に示す処理は実施されなくても良い。かかる場合、Ｓ１０８でＹｅｓと判定されると、Ｓ１１１に示す処理が行われる。同様に、Ｓ１１６に示す処理は実施されてなくても良い。かかる場合、Ｓ１１５でＹｅｓと判定されると、Ｓ１１７に示す処理が行われる。 In the present embodiment, an example has been described in which the process shown in S110 is performed before the process shown in S111 is performed. As another example, the process shown in S110 may not be performed. In such a case, if it is determined as Yes in S108, the process shown in S111 is performed. Similarly, the process shown in S116 may not be performed. In such a case, if it is determined as Yes in S115, the process shown in S117 is performed.
　本実施の形態では、第１専用運転及び第２専用運転が行われている間は、自動運転が実施されない例について説明した。他の例として、第１専用運転及び第２専用運転よりも自動運転を優先して実施しても良い。かかる場合、例えば、監視装置１４では、Ｓ３０１でＹｅｓと判定されても、呼びがなく且つかご１１が無人である状態が一定時間継続しなければ、Ｓ３０２に示す処理は開始されない。また、第１専用運転が行われている時に呼びが発生すると、第１専用運転が中断されて自動運転が開始される。同様に、第２専用運転が行われている時に呼びが発生すると、第２専用運転が中断されて自動運転が開始される。他の方法によって自動運転を優先しても良い。 In this embodiment, an example in which automatic operation is not performed while the first exclusive operation and the second exclusive operation are being performed has been described. As another example, priority may be given to automatic operation over the first exclusive operation and the second exclusive operation. In such a case, for example, the monitoring device 14 does not start the processing shown in S302 unless the state in which there is no call and the car 11 is unmanned continues for a certain period of time even if it is determined as Yes in S301. Further, when a call is generated while the first exclusive operation is being performed, the first exclusive operation is interrupted and the automatic operation is started. Similarly, if a call occurs while the second exclusive operation is being performed, the second exclusive operation is interrupted and automatic operation is started. Priority may be given to automatic driving by other methods.
