The power failure operation device 12 controls the shut-off device 10 for normal use when an abnormality such as an earthquake or fire is detected by the abnormality detection device 11 and a power failure of the utility power source 7 is detected by the power failure detection device 9. The electrical connection between the power source 7 and the control panel 6 is cut off. The power failure operation device 12 has a built-in battery (emergency power supply) 13. The power failure operation device 12 can supply the power of its own internal battery 13 to the power conversion device 8 of the control panel 6 by turning on the normally open switch 14. Further, the power failure operation device 12 can directly supply the power of its own internal battery 13 to the hoist 5 by turning on the normally open switch 15.

The safety device 16 urgently stops the car 2 when an abnormality such as an earthquake or fire is detected by the abnormality detection device 11.

The brake release operation is to move the car 2 in the heavy load direction by utilizing the weight imbalance between the car 2 and the counterweight 3. The brake release operation is performed not by the control panel 6 but by the power failure operation device 12, and even if all functions of each part of the elevator are not normal, it can be executed if only some functions are normal. In the example of FIG. 2, if the three functions of the brake, door, and position switch are normal, they can be executed.
次に、本発明の実施の形態に係るエレベータの運転装置の動作について、図３のフローチャートを参照して説明する。
Next, the operation of the elevator driving apparatus according to the embodiment of the present invention will be described with reference to the flowchart of FIG.
エレベータの通常運転時に、異常検出装置１１によって地震や火災の発生が検出されると（Ｓ１０１＝ＹＥＳ）、制御盤６内の安全装置１６は、かご２を緊急停止させる（Ｓ１０２）。制御盤６は、緊急停止した箇所が丁度ドアゾーンである場合には（Ｓ１０３＝ＹＥＳ）、かご２の扉を開いて運転を停止する（Ｓ１０４）。
When the occurrence of an earthquake or fire is detected by the abnormality detection device 11 during normal operation of the elevator (S101 = YES), the safety device 16 in the control panel 6 makes an emergency stop of the car 2 (S102). When the emergency stop is just in the door zone (S103 = YES), the control panel 6 opens the door of the car 2 and stops the operation (S104).
一方、緊急停止した箇所がドアゾーンでない場合には（Ｓ１０３＝ＮＯ）、制御盤６は、安全装置１６の作動状態を確認する（Ｓ１０５）。前述したように、安全装置１６は、異常検出時に作動してかご２を緊急停止させた後、エレベータ各部の自己診断を行い、診断結果に対応する複数の信号（図２）を出力する。そして、各信号がすべて正常の場合には、安全装置１６は作動状態から解除状態に復帰し、第１の判定回路１７は判定結果として正常を出力する。
On the other hand, when the emergency stop is not in the door zone (S103 = NO), the control panel 6 confirms the operating state of the safety device 16 (S105). As described above, the safety device 16 operates at the time of detecting an abnormality to urgently stop the car 2, and then performs self-diagnosis of each part of the elevator and outputs a plurality of signals (FIG. 2) corresponding to the diagnosis results. When all the signals are normal, the safety device 16 returns from the operating state to the released state, and the first determination circuit 17 outputs normal as a determination result.
安全装置１６が解除状態（第１の判定回路１７が正常を出力）であり（Ｓ１０５＝ＮＯ）、かつ現在停電中でない場合には（Ｓ１０６＝ＮＯ）、常用電源７から供給される電力によって、制御盤６による異常時管制運転が行われる（Ｓ１０７）。具体的には、例えば地震の場合には、制御盤６は、地震規模が所定の大きさ以下であれば通常運転を継続し、所定の大きさ以上であれば、かご２を最寄り階まで走行させた後、かご２の扉を開いて運転を停止する。
When the safety device 16 is in a released state (the first determination circuit 17 outputs normal) (S105 = NO) and is not currently in a power outage (S106 = NO), the power supplied from the regular power supply 7 is An abnormal time control operation is performed by the control panel 6 (S107). Specifically, for example, in the case of an earthquake, the control panel 6 continues normal operation if the magnitude of the earthquake is less than a predetermined magnitude, and if the magnitude is greater than a prescribed magnitude, the control panel 6 runs the car 2 to the nearest floor. Then, the car 2 is opened and the operation is stopped.
また、安全装置１６が解除状態（第１の判定回路１７が正常を出力）であるが（Ｓ１０５＝ＮＯ）、現在停電中である場合には（Ｓ１０６＝ＹＥＳ）、停電時動作装置１２から供給される非常用電力によって、制御盤６による異常時管制運転が行われる（Ｓ１０８）。詳細には、停電時動作装置１２は、停電検出装置９によって常用電源７からの電力供給が停止されたことが検出されると、遮断装置１０を動作させて常用電源７と制御盤６との間の電気的な接続を遮断した後、常開のスイッチ１４をオンにして、自身の内蔵バッテリ１３の電力を制御盤６の電力変換装置８に供給する。制御盤６は、停電時動作装置１２から供給される電力によって、かご２を最寄り階まで走行させた後、かご２の扉を開いて運転を停止する。
Further, when the safety device 16 is in a released state (the first determination circuit 17 outputs normality) (S105 = NO), but is currently undergoing a power failure (S106 = YES), the power is supplied from the operation device 12 during a power failure. The emergency operation is performed by the control panel 6 by the emergency power (S108). Specifically, when the power failure detection device 9 detects that the power supply from the normal power supply 7 is stopped, the power failure operation device 12 operates the shut-off device 10 to connect the normal power supply 7 and the control panel 6. After the electrical connection between them is cut off, the normally open switch 14 is turned on to supply the power of its own internal battery 13 to the power conversion device 8 of the control panel 6. The control panel 6 stops the operation by opening the door of the car 2 after running the car 2 to the nearest floor with the electric power supplied from the operation device 12 during a power failure.
一方、ステップＳ１０５で安全装置１６が作動状態（第１の判定回路１７が異常を出力）である場合には（Ｓ１０５＝ＹＥＳ）、停電時動作装置１２は、遮断装置１０を動作させて常用電源７と制御盤６との間の電気的な接続を遮断した後、常開のスイッチ１５をオンにして、自身の内蔵バッテリ１３の電力を制御盤６の電力変換装置８に供給する（Ｓ１０９）。この電源リセットに相当する動作が行われた後、制御盤６は、安全装置１６の作動状態を再度確認し（Ｓ１１０）、安全装置１６が解除状態（第１の判定回路１７が正常を出力）に復帰した場合には（Ｓ１１０＝ＮＯ）、ステップＳ１０７と同様に、停電時動作装置１２から供給される非常用電力によって、制御盤６による異常時管制運転が行われる（Ｓ１１１）。
On the other hand, when the safety device 16 is in an operating state (the first determination circuit 17 outputs an abnormality) in step S105 (S105 = YES), the power failure operation device 12 operates the shut-off device 10 to operate the normal power supply. After disconnecting the electrical connection between the control panel 6 and the control panel 6, the normally open switch 15 is turned on to supply the power of its own internal battery 13 to the power converter 8 of the control panel 6 (S109). . After the operation corresponding to the power reset is performed, the control panel 6 confirms again the operating state of the safety device 16 (S110), and the safety device 16 is released (the first determination circuit 17 outputs normal). When returning to (S110 = NO), similarly to step S107, the emergency control operation by the control panel 6 is performed by the emergency power supplied from the power failure operation device 12 (S111).
ステップＳ１０９で電源リセットを行った後も、安全装置１６が作動状態（第１の判定回路１７が異常を出力）のままである場合には（Ｓ１１０＝ＹＥＳ）、停電時動作装置１２は、制御盤６の第２の判定回路１８の出力する判定結果を調べる（Ｓ１１２）。前述したように、第２の判定回路１８は、安全装置１６からの各信号のうち幾つかが異常である場合でも、ブレーキ開放運転を行う際に最低限必要な箇所のみが正常である場合には、判定結果として正常を出力する。
If the safety device 16 remains in the operating state (the first determination circuit 17 outputs an abnormality) after the power reset in step S109 (S110 = YES), the power failure operation device 12 controls the power failure. The determination result output from the second determination circuit 18 of the panel 6 is examined (S112). As described above, the second determination circuit 18 is used when only a minimum necessary part for performing the brake release operation is normal even when some of the signals from the safety device 16 are abnormal. Outputs normal as a determination result.
制御盤６の第２の判定回路１８の判定結果が正常である場合には（Ｓ１１２＝ＹＥＳ）、停電時動作装置１２によるブレーキ開放運転が行われる（Ｓ１１３）。具体的には、停電時動作装置１２は、まずスイッチ１４をオフにして制御盤６の電力変換装置８への電力供給を停止すると共に、常開のスイッチ１５をオンにして、自身の内蔵バッテリ１３の電力を直接巻上機３に供給する。そして、かご２と釣合おもり３との重量のアンバランスを利用して、重負荷方向にかご２を最寄り階まで移動させた後、かご２の扉を開いて運転を停止する。なお、制御盤６の第２の判定回路１８の判定結果も異常である場合には（Ｓ１１２＝ＮＯ）、停電時動作装置１２は、第２の判定回路１８の判定結果が正常になるまで待機する。
If the determination result of the second determination circuit 18 of the control panel 6 is normal (S112 = YES), the brake release operation is performed by the power failure operation device 12 (S113). Specifically, the power failure operation device 12 first turns off the switch 14 to stop the power supply to the power conversion device 8 of the control panel 6 and turns on the normally open switch 15 to turn on its own built-in battery. 13 electric power is supplied directly to the hoisting machine 3. Then, using the unbalance of the weights of the car 2 and the counterweight 3, the car 2 is moved to the nearest floor in the heavy load direction, and then the car 2 is opened to stop the operation. When the determination result of the second determination circuit 18 of the control panel 6 is also abnormal (S112 = NO), the power failure operation device 12 waits until the determination result of the second determination circuit 18 becomes normal. To do.
以上説明したように、本発明に係るエレベータの運転装置１では、停電時動作装置１２は、安全装置１６から出力されるすべての診断信号が正常である場合には、自身の内蔵バッテリ１３の電力を使用して、制御盤６による異常時管制運転を実行させるが、安全装置１６から出力されるすべての診断信号が正常でない場合でも、ブレーキ開放運転を実行可能な必要最小限の診断信号が正常である場合には、自身の内蔵バッテリ１３の電力を使用してブレーキ開放運転を実行する。
As described above, in the elevator operating device 1 according to the present invention, the power failure operation device 12 has the power of its built-in battery 13 when all the diagnostic signals output from the safety device 16 are normal. Is used to execute the control operation at the time of abnormality by the control panel 6, but even if all the diagnostic signals output from the safety device 16 are not normal, the minimum necessary diagnostic signal that can execute the brake release operation is normal If this is the case, the brake release operation is executed using the power of its own internal battery 13.
これにより、制御盤６による異常時管制運転が不可能な場合でも、ブレーキ開放運転を行う際に必要最小限の箇所が正常である場合には、内蔵バッテリ１３の電力を使用して、停電時動作装置１２によるブレーキ開放運転を行うことができるため、災害の発生時に乗客がかご２内に閉じ込められるリスクを従来よりも少なくすることができる。
As a result, even when the control operation at the time of abnormality by the control panel 6 is impossible, if the minimum necessary part is normal when performing the brake release operation, the power of the built-in battery 13 is used to Since the brake opening operation by the operating device 12 can be performed, it is possible to reduce the risk that a passenger is trapped in the car 2 when a disaster occurs.
