MOTOR TRAIN UNIT TRACTION CONTROL SYSTEM

摘要

Disclosed is a motor train unit traction control system. A processor host of the motor train unit traction control system is connected to a lower computer board card through a CPCI bus, and comprises a rapid operation board, a network module and a debugging module. An instruction is transmitted to the lower computer board card through the CPCI bus. At the same time, the lower computer board card transmits state information to the processor host through the CPCI bus, so as to realize the overall control inside the motor train unit traction control system. A signal sampling board and the rapid operation board perform bi-directional communication through a high-speed differential LinkPort bus, so as to realize the rapid control over an inverter power module and a four-quadrant power module. The network board card performs bi-directional communication with various board cards of an I/O module through a CAN bus, and transmits digital quantity and analogue quantity signals sent by the various board cards of the I/O module to the processor host through the CPCI bus, so as to ensure the stability and the reliability of information transmission of the motor train unit traction control system.
