Title:
TRAIN-GRADE BRAKING FORCE MANAGEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2020/258486
Kind Code:
A1
Abstract:
A train-grade braking force management method, implemented by means of a braking system consisting of a train network and a braking internal network on the basis of an electronic braking control unit. When the braking internal network breaks down, the braking internal network is divided into two areas, two main control units of a fault network segment collect vehicle weight information and available air braking information of a fault local side electronic braking control unit respectively by means of the braking internal network and upload same by means of the train network, so that the main control units receive related information of a whole train and perform braking calculation and calculation of braking force applied to each vehicle, and the two main control units of the fault network segment distribute the required braking force to the fault local side electronic braking control unit by means of the braking internal network. According to the management method, the fault-tolerant operation capability of the braking system is improved, and the reliability and the safety of the braking system are improved; moreover, a whole vehicle braking force management mode is adopted, and the system braking force control precision is higher.
