Fault self-diagnosis for wireless networked sensor of robot based on fuzzy set theory

The possibility of wireless networked sensor used to monitor and control robot wireless network by Internet was discussed in this paper, and a novel fault self-diagnosis method and model for wireless networked sensor used in robot network based on the fuzzy theory was developed. The structure of wireless networked sensor, fault self-diagnosis method and model are introduced in detail. The fuzzy reasoning is a core of total diagnosis. To work out membership of state model through membership of state characteristic value, to draw a diagnosis conclusion by maximal membership or threshold were presented. Fault diagnosis of monitor and control system in high power microwave transmitter were chosen as objects of application and experiment. The results of practical application and simulate validate that correct rate of faults diagnosis can achieve 97.5%.
