The HMB 20 is installed, for example, in an elevator hall on the top floor of a building, and a hall operation panel 10-3 is installed on the operation surface of the HMB 20 in an overlapping manner.

  The hall operating panel 10-1 is provided with a hall display device 11-1 and a call registration button 12-1 that is operated when the user moves upward. Also, the hall operating panel 10-2 is operated when the hall display device 11-2, the call registration button 12-2a operated when the user moves upward, and the user moves downward. A call registration button 12-2b is provided. The hall operation panel 10-3 is provided with a hall display device 11-3 and a call registration button 12-3 that is operated when the user moves downward.

  The HMB 20 is provided with an HMB board 21, and a failure signal cut switch (FDS switch) 22 is provided on the HMB board 21. During normal operation, when a failure occurs in the elevator, a failure signal is transmitted to the monitoring center device 60 via the elevator control device 40. However, during inspection work, the FDS switch 22 is turned on by an operator. Thus, the notification of the failure signal is blocked by the elevator control device 40, and the transmission processing to the monitoring center device 60 is stopped.

  The car operation panel 30 includes an in-car display device 31, a destination floor registration button group 32 for the user to operate the destination floor, and a door open / close button 33 for the user to open and close the car. And are installed.

  When the FDS switch operation information acquisition unit 41 detects that the FDS switch 22 has been operated to the ON state and when it has detected that the FDS switch 22 has been operated from the ON state to the OFF state, the failure signal processing is performed. The detected contents are notified to the unit 42 and the device control unit 43.

  When the failure signal processing unit 42 receives a failure signal generated in a device in the elevator during normal operation, the failure signal processing unit 42 transmits the failure signal to the monitoring center device 60 via the network 50. Further, when the FDS switch operation information acquisition unit 41 notifies that the FDS switch 22 has been operated to the ON state, the process of transmitting the failure signal to the monitoring center device 60 is stopped. That is, the generated failure signal is invalidated. When the FDS switch operation information acquisition unit 41 notifies that the FDS switch 22 has been operated from the ON state to the OFF state, the failure signal transmission process to the monitoring center device 60 is restored.

  The device control unit 43 causes the hall display devices 11-1 to 11-3 and the car display device 31 to display the current position and the traveling direction of the car during normal operation. In addition, when the FDS switch operation information acquisition unit 41 notifies that the FDS switch 22 has been turned ON, a part or all of the hall display devices 11-1 to 11-3 and the car display device 31 blink. Switch to let When the FDS switch operation information acquisition unit 41 notifies that the FDS switch 22 has been operated from the ON state to the OFF state, the hall display devices 11-1 to 11-3 and the car display device 31 blink. Stop and switch to display the current position and travel direction of the car.

  When the monitoring center device 60 receives the failure signal transmitted from the elevator control device 40, the monitoring center device 60 responds to the failure signal, performs a display to notify the monitoring staff, outputs a sound, or transmits a predetermined control signal to the elevator control device 40. To do.

<Operation of Elevator System Using Elevator Control Device According to One Embodiment>
Next, the operation of the elevator system 1 according to the present embodiment will be described. FIG. 3 is a flowchart showing processing executed by the elevator control device 40 when an elevator inspection work managed by the elevator system 1 is performed.

  In the elevator system 1 according to the present embodiment, during normal operation, the platform display devices 11-1 to 11-3 and the in-car display device 31 are controlled by the device control unit 43 of the elevator control device 40, and the current position of the car and The direction of travel is displayed. In addition, when a failure signal is generated in the elevator during normal operation, the failure signal processing unit 42 of the elevator control device 40 is set to be transmitted to the monitoring center device 60 (S1).

  When the inspection operation is started in the elevator, if the operator removes the hall operation panel 10-3 and the FDS switch 22 on the HMB board 21 of the HMB 20 is turned on, the operation is controlled by the elevator control device. It is detected by 40 FDS switch operation information acquisition units 41.

  When the FDS switch operation information acquisition unit 41 detects that the FDS switch 22 has been operated to ON ("YES" in S2), the failure signal processing unit 42 and the device control unit 43 are notified (S3).

  When the failure signal processing unit 42 is notified that the FDS switch 22 has been operated to the ON state, the transmission processing of the failure signal to the monitoring center device 60 is stopped. In addition, when the device control unit 43 notifies that the FDS switch 22 has been operated to be in the ON state, a part or all of the hall display devices 11-1 to 11-3 and the car display device 31 are blinked. It is switched (S4).

  Thereafter, when the inspection work is completed and the FDS switch 22 is returned to the OFF state by the worker, the operation is detected by the FDS switch operation information acquisition unit 41 of the elevator control device 40.

  When the FDS switch operation information acquisition unit 41 detects that the FDS switch 22 has been operated from the ON state to the OFF state (S5), the failure signal processing unit 42 and the device control unit 43 are notified (S6).

  When the failure signal processing unit 42 is notified that the FDS switch 22 has been operated from the ON state to the OFF state, the failure signal transmission processing to the monitoring center device 60 is restored. When the device control unit 43 notifies that the FDS switch 22 has been operated from the ON state to the OFF state, the hall display devices 11-1 to 11-3 and the car display device 31 stop blinking, It is switched so that the current position and traveling direction of the car are displayed (S7). And it returns to the normal driving | operation process of step S1.

  According to the above embodiment, when starting the inspection work, in conjunction with the state of the FDS switch operated by the worker, in order to blink a part or the whole of the display device in the hall or the car, An operator can be notified that the FDS switch is in an ON state so that the operator can easily recognize it.

  In the above-described embodiment, the FDS switch 22 is turned on, and as shown in FIG. 1, the elevator control device 40 causes some blinking areas of the hall display devices 11-1 to 11-3 and the car display device 31. When 11 a-1 to 11 a-3, 31 a are blinking, these display devices may be displayed together with a character indicating “inspection”.

  Further, when the FDS switch 22 is in the ON state, the elevator controller 40 may turn off or blink the lights in the car. If the lights in the car are turned off or blinking, it will be inconvenient when performing inspection work in the car. Therefore, the equipment control unit 43 of the elevator control device 40 monitors whether or not there is a person in the car. When it is determined that there is a person in the car when the FDS switch 22 is ON, the car is normally illuminated. When it is determined that there is no person in the car, the car lights may be turned off or blinked. Whether or not there are people in the car is determined by the load detected by the load detector installed in the car, the image information of the surveillance camera installed in the car, or the person installed in the car. This can be determined by monitoring detection information of the sensor. By controlling in this way, when the worker finishes the inspection work and gets off from the car to the landing without turning off the FDS switch 22, the lights in the car are turned off or blinked, and the switch is surely switched. You can notice that you forgot to operate.

  Further, when the FDS switch 22 is in the ON state, the elevator control device 40 causes the call registration buttons 12-1, 12-2a, 12-2b, 12-3 of the hall operation panels 10-1 to 10-3, and The destination floor registration button 32 and the door opening / closing button 33 of the in-car operation panel 30 may be blinked. By blinking these buttons, it is possible to make it easier for the operator to recognize that the FDS switch 22 is forgotten to be turned off.
