のまま、引き続き待機させる（ステップＳ９）。The independent management device 107 constantly monitors the transmission state of the signal exchanged between the control panel 1 and the car 2 through the tail code 3, and monitors the state of the control panel 1 for a failure or damage to the tail code 3. When a transmission error occurs due to a physical failure or when a power failure occurs (step S1), the current car operation status is immediately extracted from the monitoring information immediately before the failure, and the car 2 is currently in a hall call or a car. In response to the call, it is determined whether the vehicle is operating or waiting for door closing (step S2). Here, if the car 2 is waiting for the door to be closed, it means that there is no user in the car 2, so that the car 2 is kept on standby with the door closed (step S9).

Alternatively, if the vehicle stops after moving, the stop position information is received from the car position detecting device 102, and it is determined whether or not the current car stop position is in the door opening / closing zone (step S5). Then, the guide device 105 in the car guides the door opening information and the evacuation instruction (step S6), and gives a door opening command to the car door control device 103 through the signal input / output device 101 to open the door and evacuate the user (step S6). Step S7). On the other hand, if the car stop position is not the door openable / closable zone, the in-car guide device 105 is instructed to indicate that a failure has occurred and that the car has been waiting for a while (step S8).

When an abnormality in the transmission signal exchanged between the control panel and the car via the tail code is detected, it is determined whether or not the car door can be opened based on the car position and the car speed. If any, the passengers in the car are moved down by opening the door, and the passenger in the car can be safely evacuated when an abnormality occurs in the transmission system using the tail code, preventing the trapping accident. be able to.

And determines whether the car door can be controlled to be opened based on the car position detection signal and the car speed detection signal.If the door opening control is possible, the door control device operates the door to open the passengers in the car. When the normal current detection supplied through the tail cord is lost, the user in the car can be safely evacuated, and a trapping accident can be prevented.
