　運転制御部４１は、自動運転、管制運転、及び復旧運転を行う。自動運転は、登録された呼びにかご１を順次応答させるための運転である。管制運転は、地震が発生した直後に、かご１内の乗客を避難させるための運転である。復旧運転は、復旧の可否を判定するための運転である。復旧運転は、地震が発生した後にかご１を実際に移動させることによって行われる。 The operation control unit 41 performs automatic operation, controlled operation, and recovery operation. Automatic operation is operation for sequentially responding to registered calls by car 1 . Control operation is an operation for evacuating passengers in the car 1 immediately after an earthquake occurs. The recovery operation is an operation for determining whether or not recovery is possible. Recovery operation is performed by actually moving the car 1 after an earthquake occurs.
　以下に、図３から図５も参照し、エレベーター装置の動作について詳しく説明する。図３及び図４は、実施の形態１におけるエレベーター装置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。 The operation of the elevator device will be described in detail below with reference to FIGS. 3 to 5 as well. 3 and 4 are flowcharts showing an operation example of the elevator device according to Embodiment 1. FIG. 3 and 4 show a sequence of operations.
　制御装置６では、運転制御部４１が自動運転を行う（Ｓ１０１）。自動運転が行われていれば、乗客は、かご１に乗って目的階に行くことができる。運転制御部４１が自動運転を行っている間、制御装置６では、地震が発生したか否かが判定される（Ｓ１０２）。地震計１３から制御装置６に対して特定の信号が入力されると、Ｓ１０２でＹｅｓと判定される。 In the control device 6, the operation control unit 41 performs automatic operation (S101). If automatic operation is performed, the passenger can get on the car 1 and go to the destination floor. While the operation control unit 41 is automatically operating, the control device 6 determines whether or not an earthquake has occurred (S102). When a specific signal is input from the seismometer 13 to the control device 6, a determination of Yes is made in S102.
　Ｓ１０２でＹｅｓと判定されると、制御装置６では、第１開始条件が成立するか否かが判定される（Ｓ１０３）。第１開始条件は、管制運転を開始するための条件である。一例として、特定のレベル以上の加速度が検出されたことを示す信号が地震計１３から制御装置６に入力され、且つかご１が移動中であれば、Ｓ１０３でＹｅｓと判定される。Ｓ１０３でＹｅｓと判定されると、運転制御部４１は管制運転を行う（Ｓ１０４）。管制運転では、かご１が最寄り階の乗場１４に停止する。かご１が乗場１４に停止すると、ドア２１が開放される。 When it is determined as Yes in S102, the control device 6 determines whether or not the first start condition is satisfied (S103). The first start condition is a condition for starting controlled operation. As an example, if a signal indicating that an acceleration equal to or higher than a specific level has been detected is input from the seismometer 13 to the control device 6 and the car 1 is moving, a determination of Yes is made in S103. If determined as Yes in S103, the operation control unit 41 performs controlled operation (S104). In controlled operation, the car 1 stops at the landing 14 of the nearest floor. When the car 1 stops at the landing 14, the door 21 is opened.
　次に、制御装置６では、第２開始条件が成立するか否かが判定される（Ｓ１０５）。第２開始条件は、復旧運転を開始するための条件である。一例として、特定のレベル以上の加速度が検出されたことを示す信号が地震計１３から制御装置６に入力され、且つ停止しているかご１が無人であれば、Ｓ１０５でＹｅｓと判定される。Ｓ１０５でＹｅｓと判定されると、運転制御部４１は復旧運転を開始する（Ｓ１０６）。 Next, the control device 6 determines whether or not the second start condition is satisfied (S105). The second start condition is a condition for starting recovery operation. As an example, if a signal indicating that an acceleration of a specific level or higher has been detected is input from the seismometer 13 to the control device 6, and if the stopped car 1 is unmanned, the determination in S105 is Yes. If determined as Yes in S105, the operation control unit 41 starts recovery operation (S106).
　復旧運転が行われている時に、制御装置６によって復旧用データが取得される（Ｓ１０７）。また、復旧運転が行われている時に、監視装置８の取得部５１によって確認用データが取得される（Ｓ１０８）。 　While the recovery operation is being performed, the control device 6 acquires recovery data (S107). Also, while the recovery operation is being performed, the confirmation data is acquired by the acquisition unit 51 of the monitoring device 8 (S108).
　復旧用データは、復旧の可否を制御装置６において自動判定するために必要なデータである。異常検出部４２は、Ｓ１０７で取得された復旧用データに基づいて、異常を検出する。一例として、復旧用データには、巻上機５のトルク値が含まれる。復旧用データに、インターホン２６によって取得された音声データが含まれても良い。異常検出部４２は、取得したトルク値が基準範囲に入っていなければ異常を検出する。異常検出部４２は、取得した音声データの最大値が基準値を超える場合に異常を検出する。当該基準範囲及び基準値は、記憶部４０に予め記憶される。 The recovery data is data necessary for the control device 6 to automatically determine whether recovery is possible. The abnormality detection unit 42 detects an abnormality based on the recovery data acquired in S107. As an example, the recovery data includes the torque value of the hoist 5 . The recovery data may include voice data acquired by the intercom 26 . The abnormality detection unit 42 detects an abnormality if the acquired torque value does not fall within the reference range. The anomaly detection unit 42 detects an anomaly when the maximum value of the acquired audio data exceeds a reference value. The reference range and reference value are stored in advance in the storage unit 40 .
　異常検出部４２によって異常が検出されると（Ｓ１０９のＹｅｓ）、運転制御部４１は復旧運転を中止する（Ｓ１１０）。異常検出部４２によって異常が検出されると（Ｓ１０９のＹｅｓ）、監視装置８の通信部５２は、監視センター１０に発報する（Ｓ１１０）。 When an abnormality is detected by the abnormality detection unit 42 (Yes in S109), the operation control unit 41 stops recovery operation (S110). When an abnormality is detected by the abnormality detection unit 42 (Yes in S109), the communication unit 52 of the monitoring device 8 notifies the monitoring center 10 (S110).
　異常検出部４２によって異常が検出されなければ（Ｓ１０９のＮｏ）、復旧運転が終了したか否かが判定される（Ｓ１１１）。かご１等が規定された動作を全て行い、且つ取得された全ての復旧用データについて異常が検出されなければ、Ｓ１１１でＹｅｓと判定される。 If no abnormality is detected by the abnormality detection unit 42 (No in S109), it is determined whether or not the recovery operation has ended (S111). If the car 1 etc. performs all the specified operations and no abnormality is detected in all of the acquired recovery data, the determination in S111 is Yes.
　異常検出部４２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、エレベーター装置は仮復旧する（Ｓ１１２）。仮復旧では、運転制御部４１は、登録された呼びにかご１を順次応答させる運転を行う。このため、エレベーター装置が仮復旧すると、乗客は、かご１に乗って目的階に行くことができる。 When the recovery operation ends without any abnormality being detected by the abnormality detection unit 42, the elevator device is temporarily restored (S112). In the temporary restoration, the operation control unit 41 operates to sequentially respond to the registered calls by the car 1 . Therefore, when the elevator device is temporarily restored, the passengers can get on the car 1 and go to the destination floor.
　更に、仮復旧では、通常運転では行われない特殊制御が行われる。Ｓ１１２で行われる特殊制御として、表示制御部４３は、仮復旧であることを示す特定の表示を表示器１６に行っても良い。例えば、表示制御部４３は、Ｓ１１２において乗場１４に設けられた表示灯を点滅させる。表示制御部４３は、仮復旧であることを示す特定の表示を表示器３０に行っても良い。乗客は、当該表示を見ることにより、完全な復旧ではないことを知ることができる。 In addition, during temporary restoration, special controls that are not performed during normal operation are performed. As the special control performed in S112, the display control unit 43 may perform a specific display on the display 16 indicating temporary restoration. For example, the display control unit 43 blinks the indicator lamps provided at the hall 14 in S112. The display control unit 43 may display a specific display indicating temporary restoration on the display 30 . Passengers can know that the restoration is not complete by looking at the display.
　異常検出部４２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、通信部５２は、取得部５１によって取得された確認用データを監視センター１０のサーバ１１に送信する（Ｓ１１３）。当該確認用データは、監視センター１０にいる専門知識を有する技術者が、エレベーター装置を本復旧させても良いか判断するために用いられる。 When the recovery operation ends without any abnormality being detected by the abnormality detection unit 42, the communication unit 52 transmits the confirmation data acquired by the acquisition unit 51 to the server 11 of the monitoring center 10 (S113). The confirmation data is used by a technician with specialized knowledge in the monitoring center 10 to determine whether the elevator system can be fully restored.
　確認用データには、カメラ３１によって取得された画像データが含まれる。確認用データに、カメラ３３によって取得された画像データが更に含まれても良い。また、確認用データには、マイクロホン３４によって取得された音声データ、及び振動センサ３５によって取得された振動データも含まれる。 The confirmation data includes image data acquired by the camera 31. The confirmation data may further include image data acquired by the camera 33 . The confirmation data also includes audio data acquired by the microphone 34 and vibration data acquired by the vibration sensor 35 .
　確認用データにカメラ３１によって取得された画像データが含まれるため、当該画像データは、復旧用データに含まれなくても良い。確認用データにマイクロホン３４によって取得された音声データが含まれるため、当該音声データは、復旧用データに含まれなくても良い。復旧用データにインターホン２６によって取得された音声データが含まれる場合、当該音声データは、確認用データに含まれなくても良い。 Since the image data acquired by the camera 31 is included in the confirmation data, the image data need not be included in the recovery data. Since the confirmation data includes the voice data acquired by the microphone 34, the voice data need not be included in the recovery data. If the recovery data includes voice data acquired by the intercom 26, the voice data may not be included in the confirmation data.
　図５は、サーバ１１の動作例を示すフローチャートである。サーバ１１では、確認用データを受信したか否かが判定される（Ｓ２０１）。Ｓ１１３で監視装置８から送信された確認用データをサーバ１１が受信すると、Ｓ２０１でＹｅｓと判定される。 FIG. 5 is a flowchart showing an operation example of the server 11. FIG. The server 11 determines whether or not confirmation data has been received (S201). When the server 11 receives the confirmation data transmitted from the monitoring device 8 in S113, it is determined as Yes in S201.
　Ｓ２０１でＹｅｓと判定されると、サーバ１１は、確認用データを表示器１７に表示する（Ｓ２０２）。例えば、サーバ１１は、カメラ３１によって取得された画像データをパノラマ化して表示器１７に表示する。これにより、技術者は、監視センター１０において昇降路３の全体を確認することができる。他の例として、サーバ１１は、マイクロホン３４によって取得された音声データ及び振動センサ３５によって取得された振動データに対して周波数分析を行う。サーバ１１は、周波数分析の結果を表示器１７に表示しても良い。 When determined as Yes in S201, the server 11 displays the confirmation data on the display 17 (S202). For example, the server 11 converts the image data acquired by the camera 31 into a panorama and displays it on the display 17 . This allows the engineer to check the entire hoistway 3 at the monitoring center 10 . As another example, the server 11 performs frequency analysis on the audio data acquired by the microphone 34 and the vibration data acquired by the vibration sensor 35 . The server 11 may display the frequency analysis result on the display 17 .
　Ｓ２０２では、技術者が以下の事項を確認することができるような表示が行われることが望ましい。
・ガバナロープの引っ掛かりの有無
・昇降路機器の破損の有無、昇降路外壁の破損の有無
・かご内機器の破損の有無
・乗場のドア装置の破損の有無
　また、異常検出部４２では異常を検出することができないような事象を表示器１７から読み取ることができるように、確認用データには、復旧用データに含まれていないデータが含まれていることが望ましい。 In S202, it is desirable to display a display that allows the engineer to confirm the following items.
・Presence or absence of catching of the governor rope ・Presence or absence of damage to the hoistway equipment, presence or absence of damage to the outer wall of the hoistway ・Presence or absence of damage to the equipment inside the car ・Presence or absence of damage to the door device of the landing The confirmation data desirably includes data that is not included in the recovery data so that an event that cannot be detected can be read from the display 17 .
　Ｓ２０２において確認用データの表示が行われると、サーバ１１では、復旧が許可されたか否かが判定される（Ｓ２０３）。技術者は、確認用データを確認してエレベーター装置を本復旧させても良いと判断すると、特定の操作を行う。例えば、表示器１７に表示された特定の釦がクリックされると、Ｓ２０３でＹｅｓと判定される。Ｓ２０３でＹｅｓと判定されると、Ｓ２０１で確認用データを送信してきたエレベーター装置に対し、サーバ１１から復旧信号が送信される（Ｓ２０４）。 When the confirmation data is displayed in S202, the server 11 determines whether recovery is permitted (S203). When the engineer confirms the confirmation data and determines that the elevator apparatus can be fully restored, the engineer performs a specific operation. For example, when a specific button displayed on the display 17 is clicked, a determination of Yes is made in S203. If it is determined as Yes in S203, a restoration signal is transmitted from the server 11 to the elevator device that has transmitted the confirmation data in S201 (S204).
　制御装置６では、Ｓ１１３で監視装置８の通信部５２から確認用データが送信されると、その応答としてサーバ１１から復旧信号を受信したか否かが判定される（Ｓ１１４）。Ｓ２０４でサーバ１１から送信された復旧信号を通信部５２が受信すると、Ｓ１１４でＹｅｓと判定される。 In the control device 6, when the confirmation data is transmitted from the communication unit 52 of the monitoring device 8 in S113, it is determined whether or not a restoration signal has been received from the server 11 as a response (S114). When the communication unit 52 receives the recovery signal transmitted from the server 11 in S204, it is determined as Yes in S114.
　Ｓ１１４でＹｅｓと判定されると、エレベーター装置は本復旧する（Ｓ１１５）。即ち、Ｓ１１４でＹｅｓと判定されると、運転制御部４１は通常運転を再開する。また、Ｓ１１４でＹｅｓと判定されると、Ｓ１１２で開始された特殊制御が終了する。仮復旧であることを示す特定の表示が表示器１６で行われていれば、表示制御部４３は、表示器１６から当該特定の表示を消す。仮復旧であることを示す特定の表示が表示器３０で行われていれば、表示制御部４３は、表示器３０から当該特定の表示を消す。 If it is determined as Yes in S114, the elevator device is fully restored (S115). That is, when it is determined as Yes in S114, the operation control unit 41 resumes normal operation. Also, if it is determined as Yes in S114, the special control started in S112 ends. If a specific display indicating temporary restoration is displayed on the display 16 , the display control unit 43 erases the specific display from the display 16 . If a specific display indicating temporary restoration is displayed on the display 30 , the display control unit 43 erases the specific display from the display 30 .
　本実施の形態に示す例では、地震後に復旧運転が自動的に開始される。また、異常が検出されることなく復旧運転が終了すれば、エレベーター装置は仮復旧する。このため、エレベーター装置の復旧（仮復旧）を早期に行うことができる。また、本実施の形態に示す例では、エレベーター装置を本復旧するために、技術者が現地に行って確認作業を行う必要がない。このため、地震後の技術者の負担を軽減できる。 In the example shown in this embodiment, recovery operations are automatically started after an earthquake. Further, if the restoration operation is completed without detecting any abnormality, the elevator device is temporarily restored. Therefore, restoration (temporary restoration) of the elevator device can be performed early. Further, in the example shown in the present embodiment, there is no need for an engineer to go to the site and perform confirmation work in order to fully restore the elevator device. Therefore, the burden on engineers after an earthquake can be reduced.
　なお、エレベーター装置を本復旧するために技術者が確認する確認用データは、復旧運転が行われている時に取得される。復旧運転では、例えば、かご１が各乗場１４に停止し、各乗場１４においてドア２１の開閉が行われる。このため、技術者は、監視センター１０において、乗場１４のドア装置の破損の有無、及び外壁の破損の有無といった、復旧用データからでは異常を検出できないような事象を確認することができる。 In addition, the confirmation data that the engineer confirms in order to fully restore the elevator equipment is obtained when the restoration operation is being performed. In the recovery operation, for example, the car 1 stops at each landing 14 and the doors 21 are opened and closed at each landing 14 . Therefore, at the monitoring center 10, the engineer can confirm events that cannot be detected from the recovery data, such as whether the door device of the hall 14 is damaged or not, and whether the outer wall is damaged.
