Train traction-brake controller system of urban rail transit and working method of system

Abstract

The invention discloses a train traction-brake controller system of urban rail transit and a working method of the system. The system comprises a data input module, a train operation simulation module and a communication interface module; the data input module provides initial parameters for the controller system, and operates the initial parameters; according to the initial parameters, the train operation simulation module obtains traction-brake force information of a train, line information and train attributes, carries out dynamics operation to determine the acceleration and speed of the train at present, and implements a fault simulated calculation on the train; and the communication interface module receives an ATO / ATP control instruction, sends train speed and position information, calculated by the train operation simulation module, to an ATO / ATP, and communicates with a motor to control operation of the motor. According to the route and train information, the traction-brake operation state of the train is simulated, and the working system serves as a test system for the train ATO / ATP to verify the accuracy and reliability of the train ATO / ATP.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to an urban rail transit vehicle-mounted traction brake controller system and a working method thereof. Background technique [0002] Almost all large and medium-sized cities in our country use urban rail transit as the backbone of the entire urban transportation system, and our country is ushering in a round of urban rail construction upsurge. 10 cities including Beijing, Shanghai, Tianjin, Guangzhou, Changchun, Dalian, Shenzhen, Wuhan, Nanjing, and Chongqing have opened and operated lines with a length of 770 kilometers. The above-mentioned 10 cities plus Shenyang, Chengdu, Hangzhou, Xi'an, Suzhou, a total of 15 cities under construction, have a total length of 1100km. According to the current development speed of construction of 100-120 kilometers per year, by 2020, my country's urban rail transit lines will reach 2,000-2,500 kilometers. In particular, the rail trans...

Problems solved by technology

However, the current test system still has the following problems: it cannot accurately restore the real-time line conditions of the train, and the accuracy is low; the simulation of the fault situation of the train is not comprehensive enough, and it cannot truly reproduce the fault situation of the train. Therefore, the fault tolerance of the ATO / ATP system The rate is low, and the security and stability of the ATO / ATP system are poor
