Abstract

The invention relates to a train speed limitation control method based on a train network system. According to the method, an air braking system and a traction system can send the respective states and fault information of the air braking system and the traction system to a TCMS (Train Control and Management System), the TCMS works out loss (fault) condition of air braking and electric braking through comprehensive analysis, so as to judge the highest speed limit of a train and execute speed limitation in the following two manners: the TCMS sends a speed limitation instruction to a traction control unit through a network bus, and when the traction control unit detects a network bus signal indicating that speed limitation is in need, a corresponding speed limitation mode is carried out to ensure that the train is not overspeed; the TCMS sends a speed limitation mode to be executed to a driver display screen to be displayed so as to mind a driver, and then the driver operates a driver master controller to enter into a corresponding speed limitation mode. The train speed limitation control method is based on the train network control system and has the advantages that speed limitation grades and speed limitation values at all grades can be adjusted according to project characteristics, so the train speed limitation control system has very strong portability and expandability.

Description

technical field [0001] The invention relates to a train speed limit control method based on a train network system. Background technique [0002] The brake device is an indispensable device to ensure the safe operation of the train. The sources of braking force of subway trains mainly include the air brake device provided by each car and the electric brake device provided by the traction equipment on the train. Only sufficient braking force can ensure that the running train decelerates as required or stops within a specified distance. Therefore, if there is a loss of braking force, the train needs to enter the corresponding speed limit mode to ensure that the train is in a safe running state. [0003] At present, the source of the speed limit command of the subway train is mainly the speed limit mode command of the driver's main controller. The speed limit modes of the driver main controller mainly include: forward speed limit (RMF, speed limit 25km / h), car wash mode (WM,...
