  Next, the operation of the elevator operating device in the present embodiment will be described based on the flowcharts of FIGS. 3 and 4. First, in step S1, it is determined whether a power failure has occurred. Step S1 constitutes a power failure determination means for determining whether or not a power failure has occurred. In addition, this power failure is taken as the case where both the power supply device and the backup power supply apparatus which consists of private power generation facilities fail. Further, the determination in step S1 may be performed at a constant cycle, or the occurrence of a power failure may be detected by receiving an abnormal signal from the power supply device and the standby power supply device. In step S1, when a power failure has not occurred (that is, when one of the power supply device and the standby power supply device is normal), the process proceeds to step S19 and normal operation is performed. On the other hand, when it is detected in step S1 that a power failure has occurred, the process proceeds from step S1 to step S2, and the display 13 and / or the alarm device 14 causes a power failure to the passenger in the elevator car and at the landing. Inform about the occurrence. Next, it progresses to step S3 and it is determined whether the rescue operation car switch 11 provided in the elevator car for a firefighter to operate in an emergency is ON. If not, the process proceeds to step S4. In step S4, it is determined whether or not the rescue operation hall switch 10 provided at the hall for the firefighter to operate in an emergency is turned on. Steps S3 and S4 constitute a mode determination unit that determines whether or not the operation mode is the rescue operation mode. If it is determined in step S4 that the rescue operation hall switch 10 is not turned on, the process proceeds to step S5. In step S5, a dedicated car call registered by operating the dedicated car destination button 5 installed in the car for passengers who are not easy to get on and off the elevator, such as wheelchair users and senior citizens, is registered. It is determined whether or not. Step S5 constitutes a general / dedicated determination means for determining whether the operation mode is the general operation mode or the dedicated operation mode. If it is determined in step S5 that the dedicated car call is not registered, the process proceeds to step S6, and the car is driven at a low speed to the nearest floor. At this time, all calls are invalidated. Next, it progresses to step S7, a cage | basket | car stops at the nearest floor, and opens a door. Thereby, even if a general passenger exists in the car, it is possible to get off at the nearest floor. Next, in step S8, it is counted whether or not a predetermined time (for example, 15 seconds) has elapsed, and when it has elapsed, the process proceeds to step S9, the door is closed and the operation is stopped, Conserve battery capacity.

  On the other hand, if a dedicated car call is registered in step S5, the process proceeds from step S5 to step S10, and the car is driven at a low speed to the dedicated car call floor. At this time, calls other than the dedicated car call are invalidated. Thereby, the wheelchair user / elderly person can go to the target floor. Thereafter, the processes of steps S7 to S9 are performed to stop the operation, and to preserve the battery capacity of the battery 16 for an emergency situation.

  Further, when a fire has occurred and the rescue operation hall switch 10 is turned on by a firefighter, this is detected in step S4, and the process proceeds from step S4 to step S11 in FIG. In step S11, the car is driven at a low speed to a predetermined evacuation floor that is most easily evacuated. At this time, all calls are invalidated. Next, it progresses to step S12, a cage | basket | car stops at an evacuation floor, and opens a door. Since the rescue operation hall switch 10 operated by the firefighter is installed on the evacuation floor as a rule, the firefighter exists on the open door. All passengers present in the car will get off here. Next, the process proceeds to step S13, where it is determined whether or not the rescue operation car switch 11 is turned on. If it is not turned on, the process proceeds to step S14 and the door opening is continued. If it is detected in step S13 that the rescue operation car switch 11 is turned on, the process proceeds to step S15, and it is confirmed whether or not the battery capacity of the battery 16 is normal by the battery capacity confirmation signal from the battery capacity confirmation signal output means 9. . If normal, the process proceeds to step S16, the remaining operable time is obtained by calculation based on the battery capacity, and the remaining operable time (calculated by the indicator 13 and / or the alarm device 14 in the car is calculated. For example, 30 minutes) is displayed and / or notified. Next, it progresses to step S17, and based on the general car call by operation of a firefighter, in order to rescue a person left in the fire fighting activity or the landing, the car is run to the general landing calling floor. At this time, calls other than the general car call are invalidated. In step S15, when the battery capacity charged in the battery 16 becomes a predetermined value or less, the process proceeds to step S18, the car is returned to the evacuation floor, and the operation is stopped.

  As described above, in the present embodiment, when a dedicated car call is registered at the time of a power failure, the elevator is caused to travel to the dedicated car call floor by the battery 16, so even in the event of a power failure. When a passenger who is difficult to use the stairs, such as a wheelchair user or an elderly person, gets in the car, the passenger can be moved to the destination floor. As a result, the passenger does not have to wait until the power is restored because the stairs cannot be used even if the passenger gets off, as in the prior art, which is efficient.

  In addition, when a general car call is registered when a power outage occurs, the battery 16 causes the elevator to travel to the nearest floor with the shortest travel distance. It is possible to get off the vehicle and to preserve the battery 16 in case of an emergency such as a fire.

  In addition, when a fire broke out and the firefighter turned on the rescue operation hall switch 10, the car was stopped at the evacuation floor where the firefighter was located, regardless of whether the car call was registered. Passengers can get off at the evacuation floor, and firefighters can quickly use the elevator for rescue and fire fighting activities for those who are late.

  When the firefighter turns on the rescue operation car switch 11, the control means 12 confirms the remaining capacity of the battery 16, and the display unit 13 and / or the alarm unit 14 indicates the remaining operation time. The firefighters can perform fire fighting and rescue activities in a planned manner only for a predetermined time with battery capacity.

Embodiment 2. FIG.
In Embodiment 1 described above, the vehicle travels to the dedicated car call floor in Step S10. However, since there is a high possibility that a power outage will occur after car call registration, Upon selection, the dedicated car call registration can be canceled and the car can be run to the evacuation floor.

  In other words, an evacuation floor button is provided on the dedicated car destination button 5, and after a power failure occurs, the passenger operates the button to release the dedicated car call registration and drive the car to the evacuation floor. Can do. In addition, the dedicated car call registration can be automatically canceled and the car can travel to the evacuation floor regardless of the operation of the passenger.

  As described above, in the present embodiment, the car can be driven to the destination floor or the evacuation floor at the time of a power failure by the passenger selection.

Embodiment 3 FIG.
In the above embodiment, in step S17, other calls are invalidated and only the general car call operated by the firefighter is answered. However, in this embodiment, the dedicated hall call (or the general hall) (Including calls), passengers who have escaped at the landing call floor may be waiting for rescue. Run the car and let the firefighters rescue.

  As described above, in the present embodiment, in the event of a power failure and a fire, a wheelchair user or an elderly person who cannot use the stairs is informed of the occurrence of a power failure in step S2 and calls the elevator using the dedicated landing button 7. Therefore, in step S17, in particular, when a special hall call is registered, the car is preferentially driven to the floor without invalidating the hall call so that the firefighters can rescue. Therefore, rescue of wheelchair users and elderly people who cannot use the stairs can be preferentially performed.

Embodiment 4 FIG.
In the above embodiment, in step S6, the elevator car is caused to travel from the position of the elevator car at the time of the power failure to the nearest floor, which is closest to the elevator car. Make the elevator car run to the evacuation floor, not the floor.

  As described above, in this embodiment, when a normal operation is performed and there is no dedicated car call, and a power failure occurs, the elevator car is not the nearest floor but the entrance floor, etc. Since it was made to drive to a predetermined evacuation floor, even when a general passenger needs to evacuate, it is not necessary to move using the stairs after getting off the elevator. In addition, depending on the usage status of commercial buildings, etc., there are cases where there are floors where entry by persons other than those concerned is prohibited for the purpose of protecting information security. It can be set and is convenient.

  In the first to fourth embodiments described above, the example of switching to the rescue operation mode when the rescue operation car switch 11 and the rescue operation landing switch 10 are operated when a power failure occurs has been described. 3, when the rescue operation car switch 11 and the rescue operation hall switch 10 are operated during the normal operation of step S19 in FIG. 3, the rescue operation mode may be switched.
