Application of Neural Network in Missile Test System Fault Diagnosis
HE Xin-feng · Jisuanji fangzhen · 2005
The diagnosis and elimination of faults mainly depend on technician's experience. Because of the complexity of circuit principle in the missile test system, the quick flowage of technician is not beneficial for the accumulation of experience. For adapting the need of modern war, strengthening army's survivability and elimination faults timely, in the paper, we analyze the possible faults (including indicators, test instruments and so on ) one by one according to the circuit principle, domain expert's experience and the step of the missile test, then build the knowledge base of fault diagnosis in missile test, launch and control systems and apply BP(back-propagation)neural network to the systems. It makes the diagnosis and elimination more convenient and quicker and solves the problems of eliminating faults by manpower. This application can advance army's battle ability.
