| Abstract: | Because a certain aerial defense weapon system consists of large amounts of components and complex circuits,it is difficult to check the performance and diagnose the fault in technology support.In accordance with the actual circuit units composed by function modules,and taking the position regulator board as an example,we proposed a module diagnosis method.Neural network and pattern recognition were combined to realize the fault diagnose of the functional modules and the fault component location.Result show... |
