Train traction force and braking force distributing system based on TCMS control

Abstract

The invention discloses a train traction force and braking force distributing system based on TCMS control. The system comprises a train control and management system (TCMS), a remote input and output module (RIOM), a traction system and a braking system, and the traction system and the braking system are distributed on a train. Compared with the prior art, the train traction force and braking force distributing system has the advantages that the TCMS can directly and comprehensively control various conditions of traction force and braking force distribution of the train, a distributing result on traction force and braking force is output after reasonable operating, the traction system and the braking system are only responsible for executing the result, the train control efficiency is improved to a large degree, and the phenomenon that the traction and braking function cannot be achieved according to needs due to the fact that a controller in the traction system cannot coordinate with other braking systems in time is avoided.

Description

technical field [0001] The invention belongs to the technical field of subway train control traction force and braking force distribution, and relates to a vehicle traction force and braking force distribution system based on TCMS control. Background technique [0002] The safety and reliability of train vehicle traction and braking are the key to train operation. [0003] In the prior art, the traction of the train mainly relies on the traction converter, which independently outputs the appropriate traction force according to the total traction force requirement of the train and the state of each converter, so as to drive the motor to achieve an appropriate speed. During this process, if the traction converters cannot coordinate their outputs in time according to their own traction output capabilities, ideal traction control cannot be achieved, and it is easy to cause safety problems due to impacts caused by excessive instantaneous traction forces, or Insufficient traction...

AI Technical Summary

Problems solved by technology

[0006] The problem to be solved in the present invention is that in the traction process of the above-mentioned prior art trains, the output coordination between the traction converters cannot be carried out in time according to its own traction output capacity, or because the traction system and the braking system are opposite to each other during the braking process. The distribution of braking force is unreasonable, which seriously threatens the lack of driving safety, and provides a fast, stable and safe vehicle traction and braking force distribution system based on TCMS control
