Description

technical field [0001] The invention relates to control system technology, in particular to a train traction control system. Background technique [0002] Rail transit includes large railways, intercity trains, subways, light rails, trams and low- and medium-speed maglevs, and is the main mode for public travel. The traction and auxiliary converter system is the key core equipment of the train, which is responsible for the power drive and power supply of the train. The core part of the traction and auxiliary conversion system is the traction control system. The existing traction control system can complete the control functions, including signal detection and processing, main circuit control, control algorithm, protection logic, information processing and other control functions. [0003] In the process of carrying out the research of the present invention, the inventor finds that adopting above-mentioned existing train traction control system has the following technical de...
