This article puts forward the design of wire rope tension detection system, and emphatically expounds how to design experiment device to simulate the actual movements of jacks. In the experimental process, the adjustable rheostat is altered to change current value, to simulate the output of sensors. Through breakpoint debugging function, every export of program is verified. The comparison between actual output and program output proves the correctness of synchronization algorithms. Technological aspects like measurement system, electrical system and computer communication are verified as well.
