Abstract

The invention discloses an automatic control system and method for the stability loss of a train bogie. The control system comprises a control module, a bogie stability loss detection module, a speed detection module and a braking module, wherein the bogie stability loss detection module, the speed detection module and the braking module are connected with the control module. The bogie stability loss detection module is used for detection and used for sending bogie state information to the control module. The speed detection module is used for detection and used for sending speed information of a train to the control module. The braking module is used for braking the train according to a braking command of the control module. The control method includes the steps that multiple speed limit values are preset, the speed limit values are divided into different grades from high to low according to the speed limit values, and the speed limit values at the high grades are larger than those at the low grades; and when the train bogie loses stability, through braking, the train is made to run with the speed limit value reduced by one grade. The system has the beneficial effects that the automation degree is high, the response speed is high, manual intervention is not needed, the stability loss of the train bogie can be rapidly eliminated, the train bogie stability loss control accuracy is improved, and the safe running of the train is guaranteed.

Description

technical field [0001] The invention relates to a train control system and control method, in particular to an automatic control system and control method for train bogie instability. Background technique [0002] When the EMU bogie runs at a high speed on a straight line, it will produce lateral abnormal vibration, and the amplitude of the vibration will continue to expand with time, and in severe cases, it will cause serpentine motion instability. Bogie serpentine motion instability will affect the safety of high-speed trains, and the train control system should control the train speed according to the instability state of the train to ensure the safe operation of the train. [0003] Currently, train instability control is limited to hardware control, without automatic software control. One is to install a bogie instability detection device and related instability control circuit on the train bogie. The instability control circuit applies the maximum braking force to the ...
