Design And Development Control System Of Rail Car Transmission Test Equipment

Rail cars, as the main means of conveyance in the mission of the construction sector such as the railway equipment maintenance, overhaul and infrastructure construction, are an important part of the rail transportation. The research and manufacture of the test device of transmission system of mechanical driving rail cars is of practical significance, the results which are mainly used in no-load test of transmission, reversing box and power wheel of the mechanical transmission system after the completion of the rail car overhaul.However, there has been no use of rail transmission system test equipment in the overhaul of rail car depot. In this thesis, the research and development status and developing trend of the domestic and international rail car testing device are first analysed, and then each unit of control system are designed and developed, for the functional requirements of the intelligent test.According to the composition principle, structural features, operating requirements of the transmission, reversing box, power wheels, tests content and methods are proposed. The hardware and software design of the measurement and control system, test parameters of the system are given in detail.PLC controller are used in the core components of the control system, a reliable motor control unit, a friendly man-machine interaction unit, reasonable and efficient information acquisition unit, efficient PC communication unit are designed. PC control procedure is written with the application of VB, achieving good man-machine communication. Upper and lower computer together form a perfect distributed control system.Currently, the measurement and control system has been completed, and the entire system has been in practice. Field experiments show that the test system researched and developed by this subject is simple, information-rich, stable, and the design is reasonable and practical.
