Abstract

The invention discloses a braking force management system and method for railway vehicles. The system comprises a communication data acquisition unit, a central processing unit, a regulation and control center, a braking force distribution unit, a communication data conversion unit and a communication data mapping unit, wherein the communication data acquisition unit is responsible for acquiring state information of a vehicle and control data and state data of a traction system and a brake system from a train communication network, and the management system carries out vehicle total braking force calculation, traction system electric braking force distribution, braking system mechanical braking force distribution, electric braking / mechanical braking cooperation, distribution in the anti-skid and anti-idling control period and maintenance braking application control on all vehicles on a rail, all the components are brought into the braking force management category, and unified controlis carried out.

Description

technical field [0001] The invention relates to the control technology of rail vehicles, in particular to a braking force management system and method for rail vehicles. Background technique [0002] As the network control system of rail transit vehicles gradually matures, its stability and security continue to improve, so it undertakes more and more control functions and becomes more and more important. [0003] Vehicle braking force management is the general term for a series of control actions of the vehicle under braking conditions. The braking command and level are obtained through the signal system or the driver's cab controller, and the vehicle's network control system, traction system and braking system jointly Finish. [0004] At present, the various braking force management methods and devices implemented by the network control system have their own advantages, but they have not been able to manage all stages and various working conditions of the braking process a...
