The new type of rocket launcher equipped in our army is a mechanical-electronic product. In order to improve the technical guarantee capability of rocket launcher. It is necessary to design the technical detecting system of rocket launcher. This paper introduces the basic malfunction models of rocket launcher, analyses the operating principles and composition of detecting system, forms the overall design program of detecting system. And according to malfunction phenomena of the rocket launcher; it establishes the malfunction fuzzy diagnose model of electric operation system. We hope that the detecting system can improve the combat effectiveness of rocket launcher.
