Abstract

The invention provides a networking sorting method of a train wired electric pneumatic brake control system, relates to the field of train brake control, and solves the limitation problems of hardware dependence, bus congestion, data loss and the like in the existing method. The method comprises the following steps: performing communication networking on each component device in the wired electric pneumatic brake control system by adopting a time division multiple access technology to form a train ordering communication network; acquiring actual geographic position data of the corresponding locomotive or vehicle; the composition devices corresponding to the locomotives collect respective actual geographic position data of the composition devices corresponding to all the vehicles, and actual distance data between the vehicles and the locomotives are calculated; and completing train sequencing according to the actual geographical position data and the calculated actual distance data between each section of train and the corresponding locomotive. According to the invention, the construction cost and complexity of the system are effectively reduced, and accurate and effective transmission of the brake control signal among the vehicles of the train can be ensured based on an efficient networking sorting mode.
