However, when two or more vehicle units are coupled to operate, sometimes the length of the rail vehicle exceeds the length of a platform in some places. Then, the doors of some carriages are located outside the platform. Once the doors outside the platform are opened, passengers or staffs may get off from the doors outside the platform, resulting in casualties. Existing door control systems cannot guarantee that the doors outside the platform will not be opened.

- The above solution achieves the purpose that only the doors on a platform side and in a platform range can be opened, avoids casualties caused when passengers or staffs get off the doors outside the platform, ensures the safety of the passengers and staffs, and improves the safety of the vehicle. The rail transit vehicle has the advantages of safety and reliability, and easy to be implemented and promoted.

When the door enabling signal is valid, it indicates that the door can be controlled to be opened, otherwise the door cannot be controlled to be opened.
- The platform enabling signal is sent to the door controller by the vehicle-mounted signal device. It is confirmed whether each door on the platform side can be opened, according to the determination whether the door is on the platform side and in the platform range. When a door is on the platform side and in the platform range, the platform enabling signal of the door is valid.
- If the door opening signal, the zero-speed signal, the door enabling signal and the platform enabling signal of a door are all valid, the vehicle is stationary, the door can be controlled to be opened, and the door control switch of the door sends a door opening instruction. It is determined whether the door is on the platform side and in the platform range, which ensures that only the doors on the platform side and in the platform range can be opened, thereby avoiding casualties caused when passengers or staffs get off the doors outside the platform.
- As shown in
FIG. 1 , a door control system according to an embodiment of the present invention includes: a vehicle-mounted signal device, a door controller, a door control switch, and an external display. - The vehicle-mounted

A vehicle-mounted signal device detects a platform side, a platform length and a stop position where the rail transit vehicle locates, determines, according to a set vehicle length and door layout, which doors are on the platform side and in a platform range, and transmits a platform enabling signal to a door controller.
- S203. A door control switch sends a door opening/closing instruction, a door enabling signal, a zero-speed signal, etc.
- S204. The door controller receives a door control signal, and the door controller controls a door to be opened when a door opening signal, a zero-speed signal, a door enabling signal and a platform enabling signal are all valid; and the door is not opened when any of the door opening signal, the zero-speed signal, the door enabling signal, and the platform enabling signal is invalid.
