《第１実施形態の処理手順》
図２のフローチャートに基づき、第１実施形態のエレベータシステムの処理手順を説明する。 <<Processing procedure of the first embodiment>>
A processing procedure of the elevator system of the first embodiment will be described based on the flowchart of FIG.

割当号機決定部２１は、乗場行先階登録装置１０による行先階登録があると、利用者が乗るべきエレベータを割当てる処理を実行して割当号機を決定する。割当指令出力部２２は、割当号機決定部２１により決定されたエレベータを行先階登録に応答させるための割当指令をエレベータ制御装置３０の運転制御部３１へ出力する。これにより、割当てられたエレベータが行先階登録がされた呼出階から利用者を乗せて行先階へ移動する。 When there is destination floor registration by the hall destination floor registration device 10, the assigned elevator determination unit 21 executes processing for assigning an elevator for the user to ride, and determines the assigned elevator. The allocation command output unit 22 outputs to the operation control unit 31 of the elevator control device 30 an allocation command for making the elevator determined by the allocated elevator determination unit 21 respond to the destination floor registration. As a result, the assigned elevator picks up the user from the registered destination floor and moves to the destination floor.

このような通常運転が実行されている間に、独立運転起動操作部３２が操作され、運転制御部３１に独立運転起動が指示される（ステップＳ１YES）と、運転制御部３１は、既割当が有るか否かを判定する（ステップＳ２）。既割当が有る場合には、全ての既割当に応答する運転を実行する（ステップＳ３）。全ての既割当に応答する運転を実行した後は、群管理制御装置２０の制御から切り離されて、独立運転に移行し、エレベータを指定階へ移動させ戸開待機を実施する「指定階への引き戻し運転」を実行する。 While the normal operation is being performed, when the independent operation start operation unit 32 is operated and the operation control unit 31 is instructed to start the independent operation (step S1 YES), the operation control unit 31 It is determined whether or not there is (step S2). If there are existing allocations, the operation is executed in response to all the existing allocations (step S3). After executing the operation responding to all the allocations already made, it is cut off from the control of the group supervisory control device 20, shifts to independent operation, moves the elevator to the designated floor, and waits with the door open. Execute pull-back operation.

割当指令出力部２２から割当指令を受信していない場合は、直ぐに、独立運転に移行し、エレベータを指定階へ移動させ戸開待機を実施する「指定階への引き戻し運転」を実行する（ステップＳ４）。 If the allocation command is not received from the allocation command output unit 22, immediately shift to independent operation, move the elevator to the designated floor, and execute "pull-back operation to the designated floor" for waiting with the door open (step S4).

このように、第１実施形態によれば、乗場行先階登録装置１０を備えた乗場行先階登録システムにおいて、利用者に対して号機の割当変更があった場合でも、乗場の利用者を混乱させることなく、独立運転状態に移行させることができる。 As described above, according to the first embodiment, in the hall destination floor registration system provided with the hall destination floor registration device 10, even if there is a change in the allocation of the car to the user, the users of the hall are confused. can be shifted to the independent operation state without

独立運転解除操作部３４は、独立運転を解除する際に操作され、運転制御部３１および追加割当禁止信号出力部３３に対して独立運転解除指令を出力する。 The independent operation cancellation operation section 34 is operated when the independent operation is cancelled, and outputs an independent operation cancellation command to the operation control section 31 and the additional allocation prohibition signal output section 33 .

《第２実施形態の処理手順》
図４のフローチャートに基づき、第２実施形態のエレベータシステムの処理手順を説明する。なお、図２に示した第１実施形態のフローチャートと同一手順には同一ステップ番号を付している。 <<Processing procedure of the second embodiment>>
A processing procedure of the elevator system of the second embodiment will be described based on the flowchart of FIG. The same step numbers are assigned to the same procedures as those in the flowchart of the first embodiment shown in FIG.

独立運転起動操作部３２が操作され、運転制御部３１に独立運転起動が指示される（ステップＳ１YES）と、追加割当禁止信号出力部３３から割当号機決定部２１へ追加割当禁止信号出力が出力される。これによって、当該エレベータへの追加割当が禁止される（ステップＳ１０）。この場合、割当号機決定部２１は、追加割当禁止信号が出力されているエレベータ制御装置３０が制御するエレベータを割当号機の対象号機から外し、別のエレベータを割当号機として選定する。 When the independent operation start operation unit 32 is operated and the operation control unit 31 is instructed to start the independent operation (step S1 YES), the additional allocation prohibition signal output unit 33 outputs an additional allocation prohibition signal output to the assigned car determination unit 21. be. As a result, additional allocation to the elevator is prohibited (step S10). In this case, the assigned elevator determination unit 21 excludes the elevator controlled by the elevator control device 30 to which the additional assignment prohibition signal is output from the assigned elevators, and selects another elevator as the assigned elevator.

次いで、運転制御部３１は、既割当が有るか否かを判定する（ステップＳ２）。既割当が有る場合には、全ての既割当に応答する運転を実行する（ステップＳ３）。全ての既割当に応答する運転を実行した後は、群管理制御装置２０の制御から切り離されて、独立運転に移行し、エレベータを指定階へ移動させ戸開待機を実施する「指定階への引き戻し運転」を実行する。 Next, the operation control unit 31 determines whether or not there is already allocation (step S2). If there are existing allocations, the operation is executed in response to all the existing allocations (step S3). After executing the operation responding to all the allocations already made, it is cut off from the control of the group supervisory control device 20, shifts to independent operation, moves the elevator to the designated floor, and waits with the door open. Execute pull-back operation.

割当指令出力部２２から割当指令を受信していない場合は、直ぐに、独立運転に移行し、エレベータを指定階へ移動させ戸開待機を実施する「指定階への引き戻し運転」を実行する（ステップＳ４）。 If the allocation command is not received from the allocation command output unit 22, immediately shift to independent operation, move the elevator to the designated floor, and execute "pull-back operation to the designated floor" for waiting with the door open (step S4).

独立運転を解除するために、独立運転解除操作部３４により独立運転解除操作がされ、独立運転起動操作部３２の操作により独立運転が起動されている場合（ステップＳ１１）は、追加割当禁止信号の出力を停止し、通常運転状態へ復帰する（ステップＳ１２）。 In order to cancel the independent operation, the independent operation cancellation operation is performed by the independent operation cancellation operation unit 34, and when the independent operation is started by the operation of the independent operation start operation unit 32 (step S11), the additional allocation prohibition signal The output is stopped and the normal operating state is restored (step S12).

このように、第２実施形態によれば、確実に独立運転を解除して通常運転へ復帰させることができ、利用者へのサービス低下を防止できる。 As described above, according to the second embodiment, the independent operation can be reliably canceled and the normal operation can be resumed, thereby preventing deterioration of the service to the user.

図５は第３実施形態のエレベータシステムの構成を示すブロック図である。 <Third Embodiment>
<<Configuration of the Third Embodiment>>
FIG. 5 is a block diagram showing the configuration of the elevator system of the third embodiment.

図５に示すエレベータシステムは、第２実施形態の構成に加えて、群管理制御装置２０内に、行先階登録待ち時間管理部２３と、保守運転中止指令出力部２４を更に備えている。また、エレベータ制御装置３０内に、保守運転中止部３５を更に備えている。 In addition to the configuration of the second embodiment, the elevator system shown in FIG. 5 further includes a destination floor registration waiting time management unit 23 and a maintenance operation stop command output unit 24 in the group supervisory control device 20 . In addition, the elevator control device 30 further includes a maintenance operation suspension unit 35 .

行先階登録待ち時間管理部２３は、乗場行先階登録装置１０による行先階登録に対して、割当号機決定部２１により決定されたエレベータが乗場行先階登録装置１０の設置階への応答が完了するまでの時間を管理する。 The destination floor registration waiting time management unit 23 completes the response of the elevator determined by the assigned elevator determination unit 21 to the installation floor of the hall destination floor registration device 10 in response to the destination floor registration by the hall destination floor registration device 10. manage time to

保守運転中止指令出力部２４は、独立運転後に、保守運転へ移行した場合に、行先階登録待ち時間管理部２３で管理している時間が一定時間を超えた場合、保守運転を実施しているエレベータ制御装置３０へ保守運転中止指令を出力する。 The maintenance operation stop command output unit 24 performs maintenance operation when the time managed by the destination floor registration waiting time management unit 23 exceeds a certain time when shifting to maintenance operation after independent operation. A maintenance operation stop command is output to the elevator control device 30 .

保守運転中止部３５は、保守運転中止指令を受信すると、保守運転の中止をかご内に報知した後、保守運転を中止し、通常運転状態へ移行させる。 When the maintenance operation suspension unit 35 receives the maintenance operation suspension command, the maintenance operation suspension unit 35 notifies the maintenance operation suspension to the inside of the car, then suspends the maintenance operation and shifts to the normal operation state.

《第３実施形態の処理手順》
図６のフローチャートに基づき、第２実施形態のエレベータシステムの処理手順を説明する。なお、図４に示した第２実施形態のフローチャートと同一手順には同一ステップ番号を付している。 <<Processing procedure of the third embodiment>>
A processing procedure of the elevator system of the second embodiment will be described based on the flowchart of FIG. The same step numbers are assigned to the same procedures as those in the flowchart of the second embodiment shown in FIG.

ステップＳ４の処理で独立運転へ移行した後、他の保守モードへ移行させるか否かが判定される（ステップＳ２１）。保守モードとして、専用運転や点検運転等へ移行させる場合、保守運転が実施される（ステップＳ２１YES、Ｓ２２）。 After shifting to independent operation in the process of step S4, it is determined whether or not to shift to another maintenance mode (step S21). When shifting to a dedicated operation, an inspection operation, or the like as the maintenance mode, maintenance operation is performed (steps S21 YES, S22).

他の保守モードへ移行しない場合（ステップＳ２１NO）、指定階への引き戻し運転されて戸開待機しているエレベータが戸開待機を開始してから一定時間経過したか否かが判定される（ステップＳ２３）。例えば、戸開待機状態が１～２分経過した場合には、独立運転を継続させる必要が無いので、保守運転中止指令出力部２４から保守運転中止部３５へ中止指令が出力される。これにより、当該エレベータは通常運転に復帰する（ステップＳ２３YES、Ｓ２４）。戸開待機時間が一定時間を経過しない場合は独立運転を継続する（ステップＳ２３NO、Ｓ２５）。 If the elevator does not shift to another maintenance mode (NO in step S21), it is determined whether or not a certain period of time has elapsed since the elevator that was pulled back to the designated floor and was waiting for the door to open started waiting for the door to open (step S21: NO). S23). For example, when the door open waiting state has passed for one to two minutes, there is no need to continue the independent operation, so the maintenance operation stop command output unit 24 outputs a stop command to the maintenance operation stop unit 35 . As a result, the elevator concerned returns to normal operation (step S23 YES, S24). If the waiting time for door open does not elapse, the independent operation is continued (steps S23 NO, S25).

その後、独立運転を解除するために、独立運転解除操作部３４により独立運転解除操作がされ、独立運転起動操作部３２の操作により独立運転が起動されている場合（ステップＳ１１）は、追加割当禁止信号の出力を停止し、通常運転状態へ復帰する（ステップＳ１２）。 After that, in order to cancel the independent operation, the independent operation cancellation operation is performed by the independent operation cancellation operation unit 34, and when the independent operation is started by the operation of the independent operation start operation unit 32 (step S11), additional allocation is prohibited. The signal output is stopped, and the normal operating state is restored (step S12).

このように、第３実施形態によれば、指定階への引き戻し運転後、一定時間を超えた場合、保守運転を中止し、通常運転状態へ移行するようにしたので、通常運転への戻し忘れを防止することができ、利用者へのサービス低下を防止できる。 As described above, according to the third embodiment, when a certain period of time elapses after the return operation to the designated floor, the maintenance operation is stopped and the state is shifted to the normal operation state. can be prevented, and deterioration of service to users can be prevented.
