Large-scale simulation circuit fault diagnosis,first position the fault sub-network by dint of orientation vectors,then position the component fault of fault sub-network by dint of neural network.The diagnosis is divided into before test and after test,before test diversified fault of every sub-network should be simulated with the help of Multisim;then gain the voltage of tested node and take it as training sample of BP;once more unitary dispose the tested voltage signal and define the fault orientation vectors of network.Finally analysis the fault character by dint of BP network and diagnosis fault.
