Fire control computer power supply module fault diagnosis method

A fault diagnosis method for a power module of a fire control computer belongs to the technical field of fire control computer fault diagnosis, and comprises the following steps: step S01, performing data set division processing on acquired data; step S02, carrying out normalization processing on the data; step S03, selecting the number of hidden layer nodes; step S04, introducing the chaotic mapping into the whale optimization algorithm; step S05, introducing a self-adaptive inertia weight; step S06, setting an adaptive probability threshold value; and S07, performing parameter optimization on the BP neural network by using a whale optimization algorithm introducing an inertia weight and an adaptive probability threshold, calculating the fitness value of each whale individual, and updating the positions of the whale individuals. The whale optimization algorithm is optimized and improved by introducing chaotic mapping, an adaptive probability threshold and an inertia weight, and the optimized whale optimizati
