Switch cabinet fault fuzzy diagnosis method based on indirect temperature testing mode

The invention discloses a switch cabinet fault fuzzy diagnosis method based on an indirect temperature testing mode. According to the switch cabinet fault fuzzy diagnosis method, a conventional switch cabinet indirect temperature testing fault diagnosis method is further optimized, various indirect temperature testing fault diagnosis methods are comprehensively used, and thus multiple different fault diagnosis indexes are made. According to resources and states of fuzziness, a fuzzy diagnosis theory and a fuzzy algorithm are adopted, fuzzy subordinating degree functions of various diagnosis indexes are made, and thus a subordinating degree matrix related to fault state grades is established; through fuzzy matrix operation of relevance, a diagnosis conclusion of a fault state grade of high reliability can be made. By adopting the switch cabinet fault fuzzy diagnosis method, the diagnosis conclusion can be relatively accurate, and the conclusion uncertainty caused by fuzziness of any single diagnosis index can
