Abstract

To solve the problem of the multifarious wired connection between tested tractor and power wagon, the low working reliability and the poor motility of the tractor traction performance test system, two-cars and multicomputer communication function was developed by use of wireless communication technology. The motility of the test vehicles was enhanced. The analog quantity channel detection was carried out for the selfmade data collector. The maximum error of traction channel signal was 3 mV, and the linearity of the system was 0. 06%. The results of static test show that the system can carry out accurate and stable data transmission under good communication conditions, and the maximum effective transmission distance is 520 m. The results of dynamic test show that within the scope of the 15 m away from the car, the performance test system can conduct data collect, exchange and manage in real time. Under the condition of wireless communication and wired communication, the maximum relative error of test performance parameter of the tested tractor is 0. 98%, which is within the range of sensor precision. The results of static and dynamic contrast test show that the vibration of the traction performance test system has a certain influence on the stability of the wireless communication system. The data acceptance rate of dynamic test is 97. 36%, which meets the requirements of system stability.
