Data Fusion in Vacuum Level Measuring System
Methods of electric potential on shielding and magnetron-discharge are two ordinary methods of vacuum level measuring for vacuum circuit breakers. In this paper, the joint application of two methods is researched. The fuzzy control theory is applied, and the credibility of different measuring methods is given. Then through the application of data fusion, accuracy of vacuum level measuring is improved. At last, based on fusion matrix theory eliminating invalid data, a method of judging whether the measuring sensor is invalid is put forward, as assistant means to fuzzy control.
