Train-set traction control system

Abstract

The invention relates to the railway electronic field, in particular to a traction control system of a multi-unit train. A processor host of the train-set traction control system is connected with a lower computer board card through a CPCI bus. The train-set traction control system comprises a rapid operation plate, a network module and a debugging module. An order is transmitted to the lower computer board card through the CPCI bus, meanwhile, the lower computer board card transmits state information to the processor host through the CPCI bus, and the overall control over the interior of the train-set traction control system is achieved. A signal sampling plate and the rapid operation plate perform two-way communication through a high-speed difference LinkPort bus, the rapid control over an inverter power module and a four-quadrant power module is achieved, the network board card performs two-way communication with all board cards of an I / O module through a CAN bus, the digital value and analog quantity signal sent by all board cards of the I / O module are transmitted to the processor host through the CPCI bus, and the stability and the reliability of information transmission of the train-set traction control system are guaranteed.

Description

technical field [0001] The invention relates to the field of railway electronics, in particular, to a traction control system of an EMU train. Background technique [0002] The EMU traction control system is the core power controller of the EMU train. The EMU traction control system controls the IGBT switches of the four-quadrant rectifier, brake chopper, and traction inverter to obtain the control that meets the traction / braking performance requirements of the vehicle. [0003] The main circuit structure diagram of the current EMU traction control system is shown in figure 1 . The single-phase high-voltage power is received by the pantograph and output to the four-quadrant unit for rectification through the secondary side of the transformer. The rectified high-voltage direct current is output to the inverter power module through the intermediate DC bus. After being inverted by the inverter power module, it is output to the traction motor to control the operation of the t...
