ETC door frame system key equipment operation health evaluation method

The invention discloses an ETC door frame system key equipment operation health evaluation method, which comprises the following steps: based on door frame monitoring heartbeat data, referring to traffic department examination indexes, selecting a door frame charging success rate, a door frame plate identification success rate and a door frame communication qualification rate, and combining a door frame industrial personal computer average CPU use ratio, a memory average use ratio and a door frame RSU controller temperature in examination data to obtain an ETC door frame system key equipment operation health evaluation result. The method comprises the following steps: determining weights of related factors on indexes by using a plurality of analysis models such as average power of a portal antenna channel, main operation index factors, an entropy weight method and the like, obtaining portal operation health scores, and establishing an electromechanical equipment operation health evaluation key algorithm model
