Abstract:Testing of missile ignition circuits at this stage requires dedicated test equipment, too many types of equipment ,complicated and tedious operation methods,low test accuracyand low test efficiency,It has gradually become difficult to meet the requirements of generalization,miniaturization and high precision;Therefore,according to the test requirements of missile ignition circuits,considering a combination of reliability and economic factors,a set of ignition circuit tester which domestic seven types of missile ignition circuit tests have been developed;The ignition circuit tester has the characteristics of light weight,small size and simple operation,The first automatic test of the pyrotechnic circuit was realized,which greatly improved the test efficiency;Elaborated its system composition and working principle,introducted hardware design,system software architecture design and test process design in detail;The actual application results show:gengral electric explosion circuit tester meets testability,stability,safety and scalability requirements,greatly improving the automation and accuracy of the pyrotechnics,and the test process is safe and reliable,which has been greatly improved compared to traditional test methords,ensuring the reliability of missile launch and the success rate of flight missions.
