Abstract: The intelligent simulation system is controlled by a monolithic processor, it can acquire signal data and output analog signal with different velocity, can carry on data communication with the computer, data input or data output in any stipulated areas, implement computation and display of exploding distance of fuse, etc. The article gives the design of relative hardware circuits and software programmes. The system acts not only as a data record device and signal generation device, but also as a frequency - spectrum analysis device. Hence the system has extensive applications in fields of radio detection, automatic control and proximity fuse simulation, etc.
