In order to realize real time monitoring and controlling of mobile dynamometer vehicle test system on test process in tractor traction test system,a communication system of mobile dynamometer vehicle is studied. A wireless communication scheme between computer and monitor which is based on Windows CE operating system is proposed. The functions of the communication system and Modbus protocol between the computer and monitors are mainly expounded,and the Serial Port control is used to achieve the development of monitor communication software in the VB. NET programming environment. The communication system is verified by experiment. The test results show that the communication system is stable,and it can receive and send the data timely and accurately,and realize the real time monitoring and controlling of test data and test process. This study provides a reference for the design and development of mobile dynamometer vehicle communication system.
