Problems solved by technology
[0005] However, one of the reasons why the above-mentioned operation mode cannot be implemented is that the existing urban rail transit train control system does not support the dynamic connection and decommissioning of trains, that is, it is required that the formation of operating trains must be fixed
The reason is that in the on-board controller, parameter information such as the length of the train and the distance from the transponder antenna to the front of the car needs to be stored in advance, which cannot be changed during operation
If the train formation has changed, the data of the on-board controller must be reprogrammed to ensure that the information used in the controller is consistent with the actual train, otherwise it will lead to wrong calculation of the train position and cause serious safety problems

The present invention relates to a control method for supporting dynamic connection and unmarshalling of trains, comprising: step A: acquiring stored connection state information in the initialization stage; step B: loading the offline configuration of the corresponding marshalling according to the stored connection state; step C: Collect three sets of input signals related to the connection; step D: judge whether the state of the train connection is legal according to the collected signal, if it is legal, go to step E; if not legal, go to step F; step E: judge the current connection Whether the state is consistent with the offline configuration used in step B, if it is consistent, then execute step H; if not, then execute step G; step F: apply for emergency braking, and report an error alarm; step G: apply for emergency braking, and judge the train After stopping, rewrite the coded connection state information, and then turn to step A for reinitialization. Compared with the prior art, the invention has the advantages of high safety, high reliability, high degree of automation and the like.
Description
technical field [0001] The invention relates to the field of urban rail traffic signal control, in particular to a control method supporting dynamic train connection and decoupling. Background technique [0002] The passenger flow of urban rail transit lines is usually unevenly distributed in time, and there are obvious passenger flow peaks during commuting and commuting on weekdays. In order to keep the platform at the destination of passengers as soon as possible, more trains need to be put into operation during peak hours to improve operational capacity; while in other periods, the number of operating trains is generally reduced to avoid waste of resources caused by running empty trains. However, this mode of operation will lead to long waiting times for passengers during non-peak hours and a decrease in satisfaction. [0003] In addition, in order to solve the problem of uneven distribution of passenger flow in the lines connecting suburban new cities and the city cente...
