Rail transit car's control system

The utility model discloses a rail transit car's control system, vehicle control unit pass through vehicle network communication unit and data acquisition unit communication connection, and vehicle control unit, vehicle network communication unit and data acquisition unit all set up in quick -witted case. Because vehicle control unit and vehicle network communication unit have a same soft hardwarearchitecture, the communication interface unanimity of vehicle network communication unit and data acquisition unit, so, there are not different problems that influence the communication performancebecause of soft hardware architecture between vehicle control unit and the vehicle network communication unit, there is not the problem because of the rigid communication performance of communicationinterface nonconformity between vehicle network communication unit and the data acquisition unit yet. Consequently, this rail transit car's control system can effectively promote the communication performance of vehicle control
