Control method of train-mounted signal system for on-line double heading of trains

Abstract

The invention provides a control method of a train-mounted signal system for on-line double heading of trains. The control method comprises the steps of simultaneously providing a hardwired signal A and a hardwired signal B to the train-mounted signal system through train interface devices, not activating the hardwired signal A or the hardwired signal B in the case of no double heading of the trains, activating the hardwired signal A in the case of double heading of two A-type trains, activating the hardwired signal B in the case of double heading of two B-type trains, simultaneously activating the hardwired signal A and the hardwired signal B in the case of double heading of the A-type train and the B-type train, identifying a double heading type through train-mounted signal devices according to the two received hardwired signals, loading matched train data, performing calculation and train control operation according to the loaded train data, sending a power supply control signal through the train interface devices in the case of double heading of the trains to turn off power supply of non-control devices so as to ensure that the non-control devices quit operation, and reestablishing communication connection between the front and back train-mounted signal devices after double heading of the trains so as to be in charge of the operation and control of the trains.

Description

technical field [0001] The invention relates to an urban rail traffic signal system, in particular to train reconnection operation of the rail traffic signal system. Background technique [0002] Reconnection of trains is a common operation mode of trains, that is, two locomotives are connected to each other, and the locomotive in the forward direction is responsible for the operation. After the trains are reconnected, the number of train carriages is doubled, and the transport capacity is doubled. [0003] In the prior art, train reconnection is performed by two trains of exactly the same type, and it is impossible to realize the connection between different types of trains. [0004] In addition, in the prior art, there is no technical solution for power-off processing of non-control signal devices through hard-wire circuit isolation, thus increasing the power consumption of signal operation and making the processing logic more complicated. [0005] Furthermore, in the pr...

[0003] In the prior art, train reconnection is carried out by two trains of exactly the same type, and it is impossible to realize the connection between different types of trains

[0004] In addition, in the prior art, there is no technical solution for power-off processing of non-control signal devices through hard-wire circuit isolation, thus increasing the power consumption of signal operation and making the processing logic more complicated

[0005] Furthermore, in the prior art, the communication problem of the control devices at both ends after the connection is also a technical problem that needs to be solved urgently, which is related to the automatic end-changing or turning-back of the train.
