Fault detection method and device, electronic equipment and storage medium

The invention discloses a fault detection method. The method comprises the following steps: acquiring state monitoring parameters of a liquid cooling server; wherein the state monitoring parameters comprise at least one of liquid cooling system operation parameters, water quality index parameters and component temperature parameters; acquiring a state characterization parameter according to the state monitoring parameter, and constructing a state characterization vector according to the state characterization parameter; and performing similarity comparison on the state representation vector and the fault representation vector of each fault type to obtain a predicted fault type of the liquid cooling server. According to the technical scheme, fault prediction of the liquid cooling server is achieved, specific fault types are given, the timeliness of fault detection is improved, damage to the server caused by faults is avoided, the accuracy of fault detection is improved through acquisition of multi-type state m
