Detonation Wave Of The Cpld And Microcontroller-based Data Acquisition System Design

The explosive performance test system is primarily designed to test kinds of gun-power parameters in explosion and sent them to PC that records data and deals with them. The system has two functions: the test of speed data and the test of waveform data in explosion.In this paper, according to the practical needs and based on the study of system theory of test, a method is discussed to implement high-speed data acquire with complex programmable logic device (CPLD) and micro-controller AT89C52. The STD bus is used to connect every part of the system. The paper discussed particular the principle and circuit implementation of data store, control and communication in the course.
