The invention discloses a method and a device for determining a health state of equipment, and is used for solving the problems that the weight evaluation reasonability is difficult to ensure, and anevaluation result is possible to deviate from a real situation in the prior art. The method comprises the following steps: normalizing detection data of parameter characteristics related to the equipment; determining a single parameter evaluation set of the parameter characteristics by the normalized detection data through a fuzzy membership degree function, and determining an evaluation set of aplurality of parameter characteristics according to the single parameter evaluation set; determining weight values of the parameter characteristics through an average weight method and an entropy weight method, and determining the health state of the equipment through a formula which is as shown in the specification according to the weight values of the parameter characteristics and the evaluationset of the plurality of parameter characteristics.
Description
technical field [0001] The present invention relates to the technical field of statistics, and in particular to a method and device for determining the health status of equipment. Background technique [0002] At present, the online monitoring of most important equipment mainly judges its working status by comparing with the preset threshold value. If the detection parameter exceeds the limit, it is judged as a fault. The above detection method belongs to the binary judgment of success or failure. The result of this judgment method is simple, it cannot reflect the development trend of the equipment health status, and cannot realize the judgment and identification of the deterioration of the operation trend, and has little reference value for equipment maintenance and repair. The health status assessment method expands the status of the equipment from the original binary to multiple, covering all stages of the equipment life cycle, and can more accurately reflect the operatin...
