　図２は実施の形態１におけるエレベーターの監視装置のブロック図である。 Next, the monitoring device 20 will be described with reference to FIG.
FIG. 2 is a block diagram of the elevator monitoring device according to the first embodiment.
　図２に示されるように、監視装置２０は、エレベーター運行監視部２２と閉じ込め回避運転指令部２３とを備える。 As shown in FIG. 2, the monitoring device 20 includes an elevator operation monitoring unit 22 and a trapping avoidance operation command unit 23.
　エレベーター運行監視部２２は、巻上機モーター速度指令値記憶部２２ａと巻上機エンコーダー出力値記憶部２２ｂと調速機エンコーダー出力値記憶部２２ｃと速度比較部２２ｄとを備える。 The elevator operation monitoring unit 22 includes a hoist motor speed command value storage unit 22a, a hoist encoder output value storage unit 22b, a governor encoder output value storage unit 22c, and a speed comparison unit 22d.
　巻上機モーター速度指令値記憶部２２ａは、巻上機４のモーターの速度指令値の情報を記憶する。巻上機エンコーダー出力値記憶部２２ｂは、巻上機エンコーダー１７の出力値の情報を記憶する。調速機エンコーダー出力値記憶部２２ｃは、調速機エンコーダー１８の出力値の情報を記憶する。速度比較部２２ｄは、電気スイッチ１６が動作する直前における巻上機４のモーターの速度指令値と、電気スイッチ１６が動作する直前における巻上機エンコーダー１７および調速機エンコーダー１８の少なくとも一方の出力値を比較する。また、速度比較部２２ｄは、電気スイッチ１６が動作する直前の判定期間（例えば数秒間）における巻上機４のモーターの速度指令値と、電気スイッチ１６が動作する直前の判定期間（例えば数秒間）における巻上機エンコーダー１７および調速機エンコーダー１８の少なくとも一方の出力値とを比較するようにしてよい。 The hoist motor speed command value storage unit 22a stores information on the motor speed command value of the hoist 4.

　次に、図３を用いて、監視装置２０による電気スイッチ１６の動作状況の判定方法を説明する。
　図３は実施の形態１におけるエレベーターの監視装置による電気スイッチの動作状況の判定方法を説明するための図である。 Next, a method of determining the operation status of the electric switch 16 by the monitoring device 20 will be described with reference to FIG.
FIG. 3 is a diagram for explaining a method of determining an operating state of an electric switch by the elevator monitoring device according to the first embodiment.
　図３の左側において、横軸は、かご６の走行開始からの経過時間を示す。縦軸は、電気スイッチ１６がかご６の過速により動作した際のかご６の速度を示す。図３の右側において、横軸は、かご６の走行開始からの経過時間を示す。縦軸は、電気スイッチ１６が異物との接触により動作した際のかご６の速度を示す。 On the left side of FIG. 3, the horizontal axis indicates the elapsed time from the start of traveling of the car 6. The vertical axis represents the speed of the car 6 when the electric switch 16 operates due to the overspeed of the car 6. On the right side of FIG. 3, the horizontal axis represents the elapsed time from the start of traveling of the car 6. The vertical axis represents the speed of the car 6 when the electric switch 16 operates due to contact with foreign matter.
　図３の左側に示されるように、かご６の速度が何らかの理由により速度指令値を超えると、調速機１０において、振子１５は、かご６の速度に応じて、綱車１１の回転時の遠心力により綱車１１の半径方向の外側に広がる。さらに、かごの６の速度が予め設定した速度を越えると、振子１５は、綱車１１の半径方向の外側にさらに広がる。この際、振子１５は、電気スイッチ１６に接触する。その結果、電気スイッチ１６が動作する。 As shown on the left side of FIG. 3, when the speed of the car 6 exceeds the speed command value for some reason, the pendulum 15 of the speed governor 10 changes according to the speed of the car 6 when the sheave 11 rotates. The centrifugal force spreads to the outside of the sheave 11 in the radial direction. Further, when the speed of the car 6 exceeds the preset speed, the pendulum 15 further spreads outward in the radial direction of the sheave 11. At this time, the pendulum 15 contacts the electric switch 16. As a result, the electric switch 16 operates.
　図３の右側に示されるように、かご６の速度が速度指令値に追従している場合でも、異物が電気スイッチ１６に接触する場合もある。この場合も、電気スイッチ１６が動作する。 As shown on the right side of FIG. 3, even if the speed of the car 6 follows the speed command value, foreign matter may come into contact with the electric switch 16. In this case also, the electric switch 16 operates.
　電気スイッチ１６が動作した場合、監視装置２０は、電気スイッチ１６が動作する直前における巻上機４のモーターの速度指令値と、電気スイッチ１６が動作する直前における巻上機エンコーダー１７および調速機エンコーダー１８の少なくとも一方の出力値との差に基づいて電気スイッチ１６の動作状況を判定する。巻上機４のモーターの速度指令値と巻上機エンコーダー１７および調速機エンコーダー１８の少なくとも一方の出力値との差が予め設定された範囲内である場合、監視装置２０は、かご６の速度が異常速度ではないと判定する。この際、監視装置２０は、電気スイッチ１６の動作が異物による一時的な動作であると判定する。また、電気スイッチ１６が動作した場合、監視装置２０は、電気スイッチ１６が動作する直前の判定期間（例えば数秒間）における巻上機４のモーターの速度指令値と、電気スイッチ１６が動作する直前の判定期間（例えば数秒間）における巻上機エンコーダー１７および調速機エンコーダー１８の少なくとも一方の出力値との差に基づいて電気スイッチ１６の動作状況を判定してもよい。 When the electric switch 16 operates, the monitoring device 20 causes the motor speed command value of the hoisting machine 4 immediately before the electric switch 16 operates, and the hoisting machine encoder 17 and the speed governor immediately before the electric switch 16 operates. The operation status of the electric switch 16 is determined based on the difference between the output value of at least one of the encoders 18. If the difference between the speed command value of the motor of the hoisting machine 4 and the output value of at least one of the hoisting machine encoder 17 and the governor encoder 18 is within a preset range, the monitoring device 20 causes the car 6 It is determined that the speed is not an abnormal speed. At this time, the monitoring device 20 determines that the operation of the electric switch 16 is a temporary operation due to a foreign substance. When the electric switch 16 operates, the monitoring device 20 determines the speed command value of the motor of the hoisting machine 4 in the determination period (for example, several seconds) immediately before the electric switch 16 operates, and immediately before the electric switch 16 operates. The operating condition of the electric switch 16 may be determined based on the difference between the output value of at least one of the hoisting machine encoder 17 and the governor encoder 18 during the determination period (for example, several seconds).
　次に、図４から図６を用いて、監視装置２０の動作の概要を説明する。
　図４から図６は実施の形態１におけるエレベーターの監視装置の動作の概要を説明するためのフローチャートである。 Next, the outline of the operation of the monitoring device 20 will be described with reference to FIGS. 4 to 6.
4 to 6 are flowcharts for explaining the outline of the operation of the elevator monitoring device according to the first embodiment.
　ステップＳ１では、監視装置２０は、巻上機４のモーターの速度指令値と巻上機エンコーダー１７の出力値と調速機エンコーダー１８の出力値との記憶を開始する。その後、監視装置２０は、ステップＳ２の動作を行う。ステップＳ２では、監視装置２０は、調速機１０の電気スイッチ１６が動作したか否かを判定する。 In step S1, the monitoring device 20 starts storing the speed command value of the motor of the hoisting machine 4, the output value of the hoisting machine encoder 17, and the output value of the governor encoder 18. Then, the monitoring device 20 performs the operation of step S2. In step S2, the monitoring device 20 determines whether the electric switch 16 of the speed governor 10 has operated.
　ステップＳ２で調速機１０の電気スイッチ１６が動作していない場合、監視装置２０は、ステップＳ３の動作を行う。ステップＳ３では、監視装置２０は、かご６が目的階に到着したか否かを判定する。ステップＳ３でかご６が目的階に到着していない場合、監視装置２０は、ステップＳ２の動作を行う。ステップＳ３で監視装置２０が目的階に到着した場合、監視装置２０は、ステップＳ４の動作を行う。 If the electric switch 16 of the governor 10 is not operating in step S2, the monitoring device 20 performs the operation of step S3. In step S3, the monitoring device 20 determines whether or not the car 6 has arrived at the destination floor. When the car 6 has not arrived at the destination floor in step S3, the monitoring device 20 performs the operation of step S2. When the monitoring device 20 arrives at the destination floor in step S3, the monitoring device 20 performs the operation of step S4.
　ステップＳ４では、監視装置２０は、巻上機４のモーターの速度指令値と巻上機エンコーダー１７の出力値と調速機エンコーダー１８の出力値との記憶を停止する。監視装置２０は、巻上機４のモーターの速度指令値と巻上機エンコーダー１７の出力値と調速機エンコーダー１８の出力値との情報を破棄する。その後、監視装置２０は、動作を終了する。 In step S4, the monitoring device 20 stops storing the speed command value of the motor of the hoisting machine 4, the output value of the hoisting machine encoder 17, and the output value of the governor encoder 18. The monitoring device 20 discards the information on the speed command value of the motor of the hoisting machine 4, the output value of the hoisting machine encoder 17, and the output value of the governor encoder 18. Then, the monitoring device 20 ends the operation.
　ステップＳ２で調速機１０の電気スイッチ１６が動作した場合、監視装置２０は、ステップＳ５の動作を行う。ステップＳ５では、監視装置２０は、調速機１０の電気スイッチ１６の動作によりかご６が停止したことを把握する。その後、監視装置２０は、ステップＳ６の動作を行う。ステップＳ６では、監視装置２０は、かご６がドアゾーンの範囲に存在しているか否かを判定する。 When the electric switch 16 of the governor 10 operates in step S2, the monitoring device 20 performs the operation of step S5. In step S5, the monitoring device 20 recognizes that the car 6 has stopped due to the operation of the electric switch 16 of the speed governor 10. Then, the monitoring device 20 performs the operation of step S6. In step S6, the monitoring device 20 determines whether or not the car 6 exists in the range of the door zone.
　ステップＳ６でかご６がドアゾーンの範囲に存在している場合、監視装置２０は、ステップＳ７の動作を行う。ステップＳ７では、監視装置２０は、かごドア９が開くこと、かご６の床面と乗場３の床面との間に段差があり得ること、かごドア９が開いてから直ちにかご６の外に移動することを乗場３またはかご６に設けられたアナウンス装置に報知させてからかごドア９を開かせる。 If the car 6 exists in the range of the door zone in step S6, the monitoring device 20 performs the operation of step S7. In step S7, the monitoring device 20 determines that the car door 9 is open, that there may be a step between the floor surface of the car 6 and the floor surface of the landing 3, and that the car door 9 is immediately opened to the outside of the car 6. The announcement device provided in the hall 3 or the car 6 is notified of the movement, and then the car door 9 is opened.
　その後、監視装置２０は、ステップＳ８の動作を行う。ステップＳ８では、監視装置２０は、かご６に設けられた秤装置の出力が０％であるか否かを判定する。ステップＳ８で秤装置の出力が０％でない場合、監視装置２０は、ステップＳ９の動作を行う。ステップＳ９では、一定時間が経過したか否かを判定する。 After that, the monitoring device 20 performs the operation of step S8. In step S8, the monitoring device 20 determines whether the output of the weighing device provided in the car 6 is 0%. When the output of the weighing device is not 0% in step S8, the monitoring device 20 performs the operation of step S9. In step S9, it is determined whether or not a fixed time has elapsed.
　ステップＳ９で一定時間が経過していない場合、監視装置２０は、ステップＳ８の動作を行う。ステップＳ８で秤装置の出力が０％である場合またはステップＳ９で一定時間が経過した場合、監視装置２０は、ステップＳ１０の動作を行う。ステップＳ１０では、監視装置２０は、かごドア９が閉まることをアナウンス装置に報知させてから一定時間後にかごドア９を閉じさせる。その後、監視装置２０は、ステップＳ１１の動作を行う。 If the predetermined time has not elapsed in step S9, the monitoring device 20 performs the operation of step S8. If the output of the weighing device is 0% in step S8, or if the fixed time has elapsed in step S9, the monitoring device 20 performs the operation of step S10. In step S10, the monitoring device 20 causes the announcement device to notify that the car door 9 is to be closed, and then causes the car door 9 to be closed after a certain period of time. Then, the monitoring device 20 performs the operation of step S11.
　ステップＳ６でかご６がドアゾーンの範囲に存在していない場合にも、監視装置２０は、ステップＳ１１の動作を行う。ステップＳ１１では、巻上機４のモーターの速度指令値と巻上機エンコーダー１７の出力値と調速機エンコーダー１８の出力値との記憶を停止する。この際、監視装置２０は、巻上機４のモーターの速度指令値と巻上機エンコーダー１７の出力値と調速機エンコーダー１８の出力値との情報を速度比較部２２ｄに通知する。その後、監視装置２０は、ステップＳ１２の動作を行う。ステップＳ１２では、監視装置２０は、速度比較部２２ｄにおいて、巻上機４のモーターの速度指令値と巻上機エンコーダー１７の出力値と調速機エンコーダー１８の出力値とを比較する。 Even if the car 6 does not exist in the range of the door zone in step S6, the monitoring device 20 performs the operation of step S11. In step S11, the storage of the speed command value of the motor of the hoisting machine 4, the output value of the hoisting machine encoder 17, and the output value of the governor encoder 18 is stopped. At this time, the monitoring device 20 notifies the speed comparison unit 22d of information on the speed command value of the motor of the hoisting machine 4, the output value of the hoisting machine encoder 17, and the output value of the governor encoder 18. Then, the monitoring device 20 performs the operation of step S12. In step S12, the monitoring device 20 compares the speed command value of the motor of the hoisting machine 4, the output value of the hoisting machine encoder 17, and the output value of the governor encoder 18 in the speed comparing unit 22d.
　その後、監視装置２０は、ステップＳ１３の動作を行う。ステップＳ１３では、監視装置２０は、巻上機４のモーターの速度指令値と巻上機エンコーダー１７の出力値と調速機エンコーダー１８の出力値との比較結果に基づいて調速機１０の電気スイッチ１６の動作が異物による一時的な動作であるか否かを判定する。例えば、巻上機４のモーターの速度指令値と巻上機エンコーダー１７の出力値と調速機エンコーダー１８の出力値との差が予め設定された範囲内である場合、監視装置２０は、調速機１０の電気スイッチ１６の動作が異物による一時的な動作であると判定する。 After that, the monitoring device 20 performs the operation of step S13. In step S13, the monitoring device 20 determines whether or not the speed governor 10 has an electric value based on the comparison result of the speed command value of the motor of the hoisting machine 4, the output value of the hoisting machine encoder 17, and the output value of the speed governor encoder 18. It is determined whether the operation of the switch 16 is a temporary operation due to a foreign substance. For example, if the difference between the speed command value of the motor of the hoisting machine 4, the output value of the hoisting machine encoder 17, and the output value of the speed governor encoder 18 is within a preset range, the monitoring device 20 It is determined that the operation of the electric switch 16 of the speed machine 10 is a temporary operation due to a foreign substance.
　ステップＳ１３で調速機１０の電気スイッチ１６の動作が異物による一時的な動作でない場合、監視装置２０は、ステップＳ１４の動作を行う。ステップＳ１４では、監視装置２０は、エレベーターの運転を休止する。その後、監視装置２０は、ステップＳ１５の動作を行う。ステップＳ１５では、監視装置２０は、保守員による点検、修理等が必要であることを示す情報を情報センター装置２１に送信する。 If the operation of the electric switch 16 of the speed governor 10 is not a temporary operation due to a foreign object in step S13, the monitoring device 20 performs the operation of step S14. In step S14, the monitoring device 20 suspends the operation of the elevator. After that, the monitoring device 20 performs the operation of step S15. In step S15, the monitoring device 20 transmits to the information center device 21 information indicating that maintenance, inspection, repair, etc. by the maintenance personnel is necessary.
　その後、監視装置２０は、ステップＳ１６の動作を行う。ステップＳ１６では、保守員による点検、修理等が終了していることを条件として、監視装置２０は、エレベーターの運転を復旧させる。その後、監視装置２０は、動作を終了する。 After that, the monitoring device 20 performs the operation of step S16. In step S16, the monitoring device 20 restores the operation of the elevator on condition that inspection, repair, etc. by the maintenance personnel have been completed. Then, the monitoring device 20 ends the operation.
　ステップＳ１３で調速機１０の電気スイッチ１６の動作が異物による一時的な動作である場合、監視装置２０は、ステップＳ１７の動作を行う。ステップＳ１７では、監視装置２０は、調速機１０の電気スイッチ１６を調速機１０近傍に設けられる復帰手段により自動的に復帰または制御装置１９の制御プログラムの電気スイッチ接点をマスク処理する。その後、監視装置２０は、制御装置１９に対し、かご６を最寄階まで低速で移動させた後に当該最寄階においてかごドア９を開かせるように指令を送信する。 If the operation of the electric switch 16 of the speed governor 10 is a temporary operation due to a foreign object in step S13, the monitoring device 20 performs the operation of step S17. In step S17, the monitoring device 20 automatically restores the electric switch 16 of the speed governor 10 by the returning means provided near the speed governor 10 or masks the electric switch contact of the control program of the control device 19. After that, the monitoring device 20 sends a command to the control device 19 to move the car 6 to the nearest floor at a low speed and then open the car door 9 at the nearest floor.
　その後、監視装置２０は、ステップＳ１８の動作を行う。ステップＳ１８では、監視装置２０は、かごドア９が開くこと、かご６の床面と乗場３の床面との間に段差があり得ること、かごドア９が開いてから直ちにかご６の外に移動することをアナウンス装置に報知させてからかごドア９を開かせる。 After that, the monitoring device 20 performs the operation of step S18. In step S18, the monitoring device 20 causes the car door 9 to open, that there may be a step between the floor surface of the car 6 and the floor surface of the landing 3, and immediately after the car door 9 opens, the monitoring device 20 moves to the outside of the car 6. The announcement device is notified of the movement, and then the car door 9 is opened.
　その後、監視装置２０は、ステップＳ１９の動作を行う。ステップＳ１９では、監視装置２０は、秤装置の出力が０％であるか否かを判定する。ステップＳ１９で秤装置の出力が０％でない場合、監視装置２０は、ステップＳ２０の動作を行う。ステップＳ２０では、監視装置２０は、一定時間が経過したか否かを判定する。 After that, the monitoring device 20 performs the operation of step S19. In step S19, the monitoring device 20 determines whether the output of the weighing device is 0%. If the output of the weighing device is not 0% in step S19, the monitoring device 20 performs the operation of step S20. In step S20, the monitoring device 20 determines whether a fixed time has elapsed.
　ステップＳ２０で一定時間が経過していない場合、監視装置２０は、ステップＳ１９の動作を行う。ステップＳ１９で秤装置の出力が０％である場合またはステップＳ２０で一定時間が経過した場合、監視装置２０は、ステップＳ２１の動作を行う。ステップＳ２１では、監視装置２０は、かごドア９が閉まることをアナウンス装置に報知させてから一定時間後にかごドア９を閉じさせる。 If the fixed time has not elapsed in step S20, the monitoring device 20 performs the operation of step S19. When the output of the weighing device is 0% in step S19 or when the fixed time has elapsed in step S20, the monitoring device 20 performs the operation of step S21. In step S21, the monitoring device 20 causes the announcement device to notify that the car door 9 is to be closed, and then causes the car door 9 to be closed after a certain period of time.
　その後、監視装置２０は、ステップＳ２２の動作を行う。ステップＳ２２では、監視装置２０は、制御装置１９に遠隔試運転または運転状態診断を実施させる。その後、監視装置２０は、ステップＳ２３の動作を行う。ステップＳ２３では、監視装置２０は、診断結果に基づいてエレベーターの状態が良好であるか否かを判定する。 After that, the monitoring device 20 performs the operation of step S22. In step S22, the monitoring device 20 causes the control device 19 to perform a remote test run or a driving state diagnosis. After that, the monitoring device 20 performs the operation of step S23. In step S23, the monitoring device 20 determines whether the elevator is in a good condition based on the diagnosis result.
　ステップＳ２３でエレベーターの状態が良好である場合、監視装置２０は、ステップＳ１６の動作を行う。ステップＳ１６では、監視装置２０は、エレベーターの運転を復旧させる。その後、監視装置２０は、動作を終了する。 If the condition of the elevator is good in step S23, the monitoring device 20 performs the operation of step S16. In step S16, the monitoring device 20 restores the operation of the elevator. Then, the monitoring device 20 ends the operation.
　ステップＳ２３でエレベーターの状態が良好でない場合、監視装置２０は、ステップＳ１４の動作を行う。ステップＳ１４では、監視装置２０は、エレベーターの運転を休止させる。その後、監視装置２０は、ステップＳ１５の動作を行う。ステップＳ１５では、監視装置２０は、保守員による点検、修理等が必要であることを示す情報を情報センター装置２１に送信する。 If the condition of the elevator is not good in step S23, the monitoring device 20 performs the operation of step S14. In step S14, the monitoring device 20 suspends the operation of the elevator. After that, the monitoring device 20 performs the operation of step S15. In step S15, the monitoring device 20 transmits to the information center device 21 information indicating that maintenance, inspection, repair, etc. by the maintenance personnel is necessary.
　その後、監視装置２０は、ステップＳ１６の動作を行う。ステップＳ１６では、監視装置２０は、エレベーターの運転を復旧させる。その後、監視装置２０は、動作を終了する。 After that, the monitoring device 20 performs the operation of step S16. In step S16, the monitoring device 20 restores the operation of the elevator. Then, the monitoring device 20 ends the operation.
　以上で説明した実施の形態１によれば、監視装置２０は、巻上機４のモーターの速度指令値と巻上機エンコーダー１７の出力値と調速機エンコーダー１８の出力値との比較結果に基づいてかご６の内部に閉じ込められた利用者を救出する閉じ込め回避運転を実施するか否かを判定する。このため、調速機１０の電気スイッチ１６の動作が異物による一時的な動作である場合に利用者がかご６の内部に閉じ込められたままになることを回避することができる。 According to the first embodiment described above, the monitoring device 20 determines whether the speed command value of the motor of the hoisting machine 4, the output value of the hoisting machine encoder 17, and the output value of the governor encoder 18 are compared. Based on this, it is determined whether or not to perform the confinement avoidance operation to rescue the user who is confined inside the car 6. Therefore, it is possible to prevent the user from being trapped inside the car 6 when the operation of the electric switch 16 of the speed governor 10 is a temporary operation due to a foreign object.
　また、監視装置２０は、巻上機４のモーターの速度指令値と巻上機エンコーダー１７の出力値と調速機エンコーダー１８の出力値との差が予め設定された範囲内である場合に、閉じ込め回避運転を制御装置１９に実施させる。このため、かご６に閉じ込められた利用者を安全に救出することができる。 Further, the monitoring device 20, when the difference between the speed command value of the motor of the hoisting machine 4, the output value of the hoisting machine encoder 17, and the output value of the governor encoder 18 is within a preset range, The control device 19 is caused to perform the trapping avoidance operation. Therefore, the user trapped in the car 6 can be safely rescued.
　この際、電気スイッチ１６が動作する直前の判定期間において、巻上機４のモーターの速度指令値と巻上機エンコーダー１７の出力値と調速機エンコーダー１８の出力値とを複数点比較すれば、１点のデータ比較で判定する場合よりも、電気スイッチ１６の動作が異物による一時的な動作であるか否かをより確実に判定することができる。 At this time, if the speed command value of the motor of the hoisting machine 4, the output value of the hoisting machine encoder 17, and the output value of the governor encoder 18 are compared at a plurality of points in the determination period immediately before the operation of the electric switch 16. It is possible to more reliably determine whether or not the operation of the electric switch 16 is a temporary operation due to a foreign substance, as compared with the case of making a determination by comparing data of one point.
　また、監視装置２０は、閉じ込め回避運転を実施させる際に、かご６がドアゾーンの範囲内に存在していない場合に、かご６を最寄階まで走行させ、当該最寄階においてかごドア９を開かせる。このため、かご６に閉じ込められた利用者を早急に救出することができる。なお、ドアゾーンは、乗場３の床面とかご６の床面との高さの差が利用者の移動に差し支えない範囲となるように設定すればよい。 Further, the monitoring device 20 causes the car 6 to travel to the nearest floor when the car 6 does not exist within the range of the door zone when the confinement avoidance operation is performed, and the car door 9 is moved to the nearest floor. Let it open. Therefore, the user trapped in the car 6 can be rescued immediately. The door zone may be set so that the difference in height between the floor surface of the hall 3 and the floor surface of the car 6 is within a range that does not interfere with the movement of the user.
　また、監視装置２０は、閉じ込め回避運転を実施させる際に、かご６がドアゾーンの範囲内に存在している場合に、かご６を走行させることなく、かごドア９を開かせる。このため、かご６に閉じ込められた利用者をより早急に救出することができる。 Further, the monitoring device 20 causes the car door 9 to be opened without running the car 6 when the car 6 is within the range of the door zone when performing the trapping avoidance operation. Therefore, the user trapped in the car 6 can be rescued more quickly.
　また、監視装置２０は、かごドア９を開かせる前に、かごドア９が開いてからかご６の外に移動することを報知させる。このため、かご６に閉じ込められた利用者をかご６の外へ誘導することができる。 Also, the monitoring device 20 informs that the car door 9 will move to the outside of the car 6 after the car door 9 is opened before the car door 9 is opened. Therefore, the user trapped in the car 6 can be guided to the outside of the car 6.
　また、監視装置２０は、かごドア９を開かせた後に、秤装置が荷重を検出していない場合は、かごドア９を閉じさせる。このため、かご６に閉じ込められた利用者をかご６の外へ誘導することができる。 Also, the monitoring device 20 closes the car door 9 after the car door 9 is opened and the load is not detected by the weighing device. Therefore, the user trapped in the car 6 can be guided to the outside of the car 6.
　また、監視装置２０は、かごドア９を閉じさせる前に、かごドア９が閉じることを報知させる。このため、かご６に閉じ込められた利用者がかご６の内部に留まることを防止できる。 Also, the monitoring device 20 informs that the car door 9 will be closed before closing the car door 9. Therefore, it is possible to prevent the user who is trapped in the car 6 from staying inside the car 6.
　また、監視装置２０は、閉じ込め回避運転が実施された後、エレベーターの状態を診断し、エレベーターが異常でないと診断された場合は、エレベーターの運転を復旧させる。この際、電気スイッチ１６を初期状態に自動で戻すようにしておけばよい。この場合、電気スイッチ１６の動作が異物による一時的な動作である場合に、エレベーターの運行効率が下がることを防止できる。 Also, the monitoring device 20 diagnoses the state of the elevator after the containment avoidance operation is performed, and restores the operation of the elevator if the elevator is not abnormal. At this time, the electric switch 16 may be automatically returned to the initial state. In this case, when the operation of the electric switch 16 is a temporary operation caused by a foreign object, it is possible to prevent the operation efficiency of the elevator from being lowered.
　なお、エレベーターの復旧後、電気スイッチ１６が動作した際のかご６の位置において、電気スイッチ１６が再び動作するか否かで電気スイッチ１６の動作の原因を判定してもよい。例えば、電気スイッチ１６が動作した際のかご６の位置において、電気スイッチ１６が再び動作した場合、電気スイッチ１６が調速機ロープ１３の特定の位置に付着したゴミ、虫、鼠等の異物との接触により動作したと判定してもよい。例えば、電気スイッチ１６が動作した際のかご６の位置において、電気スイッチ１６が動作しない場合、電気スイッチ１６が落下物との接触により動作したと判定してもよい。 After the elevator is restored, the cause of the operation of the electric switch 16 may be determined by whether or not the electric switch 16 operates again at the position of the car 6 when the electric switch 16 operates. For example, when the electric switch 16 is operated again at the position of the car 6 when the electric switch 16 is operated, the electric switch 16 detects foreign matter such as dust, insects, and rats attached to a specific position of the speed governor rope 13. You may judge that it operated by the contact of. For example, when the electric switch 16 does not operate at the position of the car 6 when the electric switch 16 operates, it may be determined that the electric switch 16 has operated due to contact with a falling object.
　なお、実施の形態１の監視装置２０を機械室２のないエレベーターに適用してもよい。この場合も、調速機１０の電気スイッチ１６の動作が異物による一時的な動作である場合に利用者がかご６の内部に閉じ込められたままになることを回避することができる。 The monitoring device 20 according to the first embodiment may be applied to an elevator without the machine room 2. Also in this case, it is possible to prevent the user from being trapped inside the car 6 when the operation of the electric switch 16 of the speed governor 10 is a temporary operation due to a foreign object.
