Control and Communication Techniques of High-Speed Railway Train Wheel-Set Running-In Test Based on LabVIEW

Abstract:

The production, assembly and repair qualities of high-speed railway train wheel-set directly relates to traffic safety. It is very import to build wheel-set running-in test bench and develop high efficiency control and communication module. Running-in test methods of high-speed railway wheel-set, the communication techniques between computer and Frequency Inverter and serial port communication based on LabVIEW are introduced. The control and communication module is set up by using the Frequency Inverter, motor, serial communication card, computer and other devices. The control and communication software based on LabVIEW is developed. Working conditions are simulated effectively. The automatic testing is realized. The mutual interference of reading and writing commands to Frequency Inverter because of using one port is solved. All kinds of control and communication functions are achieved. The applications show that the design of control and communication module is reasonable, the testing process is flexible and controllable, the control and communication is accurate and efficient, the analyzed results are reliable.
