Refrigerating machine room multi-device linkage fault prediction method, medium and system

The invention provides a refrigerating machine room multi-device linkage fault prediction method, medium and system, and belongs to the technical field of refrigerating machine room fault monitoring, and the method comprises the steps: collecting the operation data of the operation of a refrigerating machine room; establishing a change rate curve of each type of operation data, and calculating primary and secondary relationships between each type of operation data and other types of operation data according to the change rate curve of each type of operation data; fusing the operation data into a comprehensive index vector by adopting a fuzzy fusion method; the method comprises the following steps: establishing a linkage relation model among multiple devices according to historically collected operation data, and predicting possible fault correlation among the devices; calculating a first threshold vector and a second threshold vector based on the operation data collected historically; and based on the acquire
