Fault recognition method and device for heating and ventilation equipment, equipment and storage medium

Abstract

The invention relates to a fault recognition method and device for heating and ventilation equipment, the equipment and a storage medium. The method comprises the steps of presetting a fuzzy search library and an exception jump library based on processing equipment so as to select a judgment word from the fuzzy search library after a detection item name is obtained, and comparing with the detection item name, and taking the judgment word of which the comparison result is matched as a preliminary recognition result; then judging whether an exception word corresponding to the preliminary recognition result in an exceptional jump library is matched with the detection item name or not; if so, selecting a judgment word which is the same as the matched exceptional word from the fuzzy search library as a final recognition result; otherwise, taking the preliminary recognition result as a final recognition result. According to the arrangement, fault recognition is performed through the processing equipment, and the processing efficiency can be effectively improved compared with manual recognition; besides, through combination of fuzzy search and an exceptional jump function, unique recognition of the test item name of the heating and ventilation equipment can be realized, and the accuracy of arecognition result is improved.

Description

technical field [0001] The present application relates to the technical field of fault identification, and in particular to a fault identification method, device, device and storage medium for HVAC equipment. Background technique [0002] HVAC equipment refers to the three related equipment of heating, ventilation and air conditioning. With the development of economy, its application in family and work environment is more and more extensive. Naturally, the fault detection and analysis involved are becoming more and more more and more. Taking the multi-connected air conditioner as an example, due to the large number of parts and complex detection technology of the whole machine, the following problems exist in the inspection and after-sales maintenance of the air conditioner in the factory: the multi-connected system is complicated, the detection parameters , it is difficult to accurately locate; the fault handling efficiency of manual identification and detection is low, an...
