Description

  The present invention relates to an elevator control device.

  Conventionally, elevator operation control during an earthquake stops when the earthquake is detected, stops at the nearest floor, opens the door for a predetermined time, closes the door, and stops operation. After that, after an inspection by an elevator specialist such as a maintenance worker, the vehicle returns to normal operation. The inspection by a specialist engineer includes confirmation of equipment in the elevator machine room and hoistway, confirmation that there are no passengers remaining in the elevator, and confirmation of low-speed traveling of the elevator.

  In addition, there is an elevator that automatically performs a diagnostic operation and recovers from an operation stop (for example, refer to Patent Document 1) for the purpose of early recovery from an operation stop state without performing an inspection by an elevator engineer.

JP-A-5-139642

  Regardless of the inspection by an elevator specialist, the elevator that automatically performs the diagnostic operation and recovers from the operation stop is run before the inspection by the elevator specialist. After the automatic diagnosis operation, there is a problem that it is difficult to perform the inspection because the elevator has already been restored when the inspection is performed by the elevator specialist.

  An object of the present invention is to provide an elevator control device that enables an elevator engineer to smoothly perform an inspection operation after a diagnostic operation automatically, regardless of an inspection by an elevator engineer.

In order to achieve the above object, the present invention is provided with a means for stopping an elevator when a magnitude of a swing of a predetermined value or more is sensed, and automatically performs a diagnostic operation when the operation is stopped to stop the operation. In the elevator control device equipped with means to recover from the above, when the seismic detector operates, the elevator in operation stops at the nearest floor, turns off the lights in the car, opens the door for a predetermined time, then closes the door If the amount of change in the car load is less than or equal to the specified value, diagnostic operation is performed.If there is no abnormality, inspection by a specialist engineer has not been performed. If the floor where no call is generated for the hall call or car call is stopped, each floor is stopped without opening the door, and after inspection by a specialist engineer is completed, Destination floor registration button and a predetermined operation of the door opening and closing button created panel, by one of the maintenance terminal is to cancel the notification and the floor stop operation.

  According to the present invention, after the automatic recovery from the operation stop after the control operation at the time of the earthquake, in order to notify the expert engineer and the elevator user of the presence or absence of the inspection by the expert engineer, Inspection can be carried out smoothly.
