Description

TECHNICAL FIELD

[0001] The present application relates to a rail transit signal system, in particular to an automatic train stopping system and method under the condition of failure of platform door linkage opening and closing. BACKGROUND

[0002] The platform door is one of the important guarantees for safe operation of urban rail transit. For the fully automatic unmanned line, the signal system automatically controls the opening and closing of the platform door according to the corresponding conditions. If the platform door linkage opening fails, the train will automatically start after the stop time ends, resulting in that the passengers at the station platform and the train cannot get on and off the train. At the same time, when the stop time ends, the train automatically closes the door, and there is a great risk of pinching people and objects between the platform door and the train door, which brings great safety risk to passengers and train operation. If the platform door linkage closing fails, there is the same risk. Even if the staff finds that the platform door linkage opening or closing fails for a short stop time (about 30S), it is difficult for manual to stop the train in time.

[0003] Therefore, how to make the platform door system under the condition of linkage opening and closing failure, the signal system automatically stops the train, improves the response efficiency of the system, improves the train safety, and reduces the labor intensity of the platform staff has become an urgent problem to be solved.

[0038] As shown in Figure 2 A FAM system platform door linkage door opening and closing failure car stopping method, the method comprises the following steps:

[0039] Step 1, after the train stops at the station and is stable, the platform operation is performed.

[0040] Step 2, the ATC system calculates the platform door opening and closing command and sends it to the interlocking system.

[0041] Step 3, after receiving the opening and closing command, the interlocking system forwards the platform door system through the relay interface.

[0042] Step 4, after receiving the opening command, the platform door system executes the opening, and after receiving the closing command, executes the closing.

[0043] Step 5, the platform door system sends the opening and closing state information to the interlocking system through the relay interface.
