Platform gap detection and train operation interlocking method

Abstract

The invention relates to a platform gap detection and train operation interlocking method. The method comprises the steps that when a signal system judges that a train door and a platform door are both closed and locked, and a starting instruction is sent to a gap detection system; the gap detection system feeds back an obstacle detection state to the signal system; and after no obstacle is determined to be left in the gap detection system, the signal system controls a train to leave a station. Compared with the prior art, the method has the advantages that the influence of interlocking on operation efficiency is effectively reduced, the influence of false alarm of the gap detection system on operation is reduced, whether an obstacle exists or not is monitored in the train departure process, and operation safety is guaranteed.

Description

technical field [0001] The invention relates to a communication-based automatic train control (CBTC) signal system, in particular to a method for platform gap detection and train operation interlocking for fully automatic driverless lines in urban rail transit. Background technique [0002] Based on the fact that there is a risk of stranded passengers in the gap between the platform door of the urban rail transit station and the train, resulting in personal injury or death of passengers, and at the same time, in the unmanned urban rail transit line, there is a lack of drivers to monitor the train operation on-site, which needs to be replaced by the system The driver automatically judges whether there are passengers stranded in the gap. [0003] In recent years, with the rapid development of intelligence and information technology, unmanned subways have also developed rapidly. More and more cities are building or planning unmanned subway lines. In order to prevent passengers ...

Problems solved by technology

[0005] At present, the platform door gap detection state is commonly used to interlock with the platform door system, that is, the gap detection information is connected to the platform door system to provide the closing and locking information of the signal system. This solution is simple in structure and easy to implement in terms of interface circuits. , but in normal operation, the platform door belongs to the controlled system, which is controlled by the signal system, and there are certain technical limitations in the degree of degradation processing and system automation:

[0006] 1) It is impossible to check whether the train doors are closed. At the same time, in order to ensure the accuracy of detection, the train is authorized to run only after there are no obstacles within the configurable time of continuous detection, which has a great impact on operational efficiency;

[0007] 2) When an obstacle or a false alarm is detected, the system only gives an alarm prompt, and cannot handle it automatically, requiring manual intervention;

[0008] 3) The detection process cannot monitor the departure process in real time. If the door is opened before the train leaves the station and passengers are squeezed into the gap, they cannot be detected
