The invention relates to the field of electromechanical equipment fault positioning, and aims at providing an electromechanical equipment fault
positioning system which comprises a
knowledge base and a box body. One side of the outer wall of the top of the box body is movably connected with a box cover through a hinge, a detection
microcomputer is installed on one side in the box body through screws, a plurality of storage grooves are formed in the side, close to the detection
microcomputer, of the box body, and a rubber convex pad matching the interior of the box body is bonded to the outer wall of the side, close to the box body, of the box cover. The
system has the beneficial effects that a
hybrid reasoning strategy is adopted, firstly, case-based reasoning is adopted to obtain a historical fault source of the fault phenomenon, if the historical fault source does not exist, rule-based reasoning is adopted to obtain a possible fault component, reverse reasoning is carried out to obtain a sign which can be caused by the fault component, and if the fault sign is confirmed through interactive inquiry, the fault source is confirmed, otherwise, reverse reasoning is carried out on the next possible fault source until the fault component is confirmed.
