Abstract:	In order to verify the main functions and performance of fuze products and improve the detection efficiency in product production, a whole process test system for fuze circuit components is designed to complete the full process test of the timing assembly function, speed correction, trigger, delay and self destruction function of fuze circuit components. The relay control module is used to accurately simulate the fuze switching signal and power on signal, and the external signal generator is used to simulate the geomagnetic signal required for fuze speed measurement, which enhances the credibility of the fuze test and reduces the complexity of the design. Using one button operation technology, the fuze time installation, trigger, delay, self destruction and other different working modes for simulation test, a set of test system can test the two appearances of the fuze, the test output results are directly read by the oscilloscope, the test time is short, the error is small, greatly improving the product testing efficiency and reducing the cost. The experimental results show that the test system can complete the whole process test of the fuze function, and the test results meet the error range required by the test system, meet the requirements of the functional design, and achieve the expected effect of the fuze circuit component test, which can provide design experience for other fuze test equipment.
