Embodiment Construction
[0049] The present invention will be specifically introduced below in conjunction with the drawings.
[0050] According to the present invention, most of the fault diagnosis methods are focused on the analysis of the sensor signal, and there are few studies on the fault location and analysis of the WSN node itself. According to the voltage and current parameters related to the fault characteristics, the concept of active in the circuit and the direction of inflow and outflow, the abnormal current or voltage of a module will affect the state of other module parameters in the entire series circuit, and the abnormal voltage or current The diagnosis can finally determine the location and cause of the fault. Establish a fuzzy neural network current model for fault diagnosis of wireless communication module. First, subtractive clustering is used to adaptively extract fuzzy rules, and then a hybrid learning method combining particle swarm optimization and partial least squares is used ...
