The control device 120 is connected. The position detection device 180 is used to detect the current position of the rail vehicle 100 and generate position information; the emergency unlock control device 120 is also used to obtain the position information according to the emergency unlock request signal; the emergency unlock control device 120 is also used to judge the position of the rail vehicle according to the position information 100 is in the position where parking is allowed; if the rail vehicle 100 is in the position where parking is allowed, it is determined that the door allows the open state to be valid; if the rail vehicle 100 is not in a position where parking is allowed, then it is determined that the door allows the open state to be invalid.

It should be understood that the position detection device 180 is connected to the transponder or sensor installed on the ground, the position detection device 180 receives the position information fed back by the transponder or the sensor, and sends the position information to the emergency unlock control device 120, and at the same time, the built-in The train site information and platform information are sent to the emergency unlocking control device 120 . The emergency unlocking control device 120 determines whether the rail vehicle 100 is in a position where parking is allowed in combination with the position information, train station information and platform information. The location where parking is allowed can be a platform area and an area with an escape platform, and the location detection device 180 can be a network system or other control systems.

If the emergency unlocking control device 120 determines that the rail vehicle 100 is in a position where parking is allowed, it will generate a signal for prohibiting the opening of the door, and the signal for prohibiting the opening of the door can be at a low level. The emergency unlocking control device 120 generates a signal for prohibiting the opening of the vehicle door, which indicates that the state of allowing the vehicle door to be opened is valid. If the emergency unlocking control device 120 determines that the rail vehicle 100 is not in the position where parking is allowed, the door opening prohibition signal will not be generated, and if the emergency unlocking control device 120 does not generate the door prohibition opening signal, it indicates that the door permitting opening state is invalid.

In this embodiment, before the emergency unlocking control device 120 obtains the location information according to the emergency unlocking request signal, it needs to determine whether the position detection device 180 has a fault, and if there is a fault, it determines that the door is allowed to open.
