An Artillery Servo System Fault Detection Study

From 1970' s the technique on analog circuit fault diagnosis has been developed very much. It' s used widely and plays a more and more important role. It makes equipment maintain change from being passive to active, being diagnosis by object data rather than by subject experience.Fault diagnosis aims at identifying the characteristics representing fault, dividing it from useless information and telling the nature, place, reason, degree.The paper analyzes the problem of selecting test nodes in antiaircraft gun servo system diagnosis using fault dictionary. Based on carving up the fuzzy sets, according to quantity of fault information, a node selecting method for real-time fault diagnosis tree is established. And the paper discusses the fault separation and the arrangement of fault dictionary in antiaircraft gun servo system fault diagnosis and presents the method for fault separation and arrangement of fault dictionary by use of fault code.The detection instrument of an antiaircraft gun servo system is a special tertiary maintain and detection instrument used in rapidly auto-detecting and fault orientation to main assembly of antiaircraft gun servo system. The detection instrument can display the result with fault code and tell the fault position by pronunciation.The paper is made up of not only theories but also practice. It gives a scientific way for fault diagnosis. It brings forth new ideas on the basis of inheritance. It is of value in the sphere of learning. I believe that the detection instrument has a good future.
