Timing Circuit Design Based on Sequential Logic and Micro-processing Technology

Qing-tian HAN


According to the need of equipment testing, the paper presented the overall scheme of timing circuit and the wiring diagram of hardware circuit, and also designed the indicator circuit, the timing software and the band switch circuit. Then modular design concept and function decomposition method were adopted, and the time sequence step-by-step technology and safety isolation technology were used to solve the difficulty and credibility of acquiring multi-functional components, multi-system modules and complex multi-channel correlated signal interference problem. Finally, the off-line debugging was carried out. The results show that the technology can test the functions and performance indexes of the plug-in board comprehensively and completely, realize the functions of depth setting system debugging, extension testing and fault precise location, and shorten the maintenance and detection time.
