Abstract

The present invention provides a method, system, memory and controller for fan health assessment, which includes: acquiring historical data of the fan during normal operation and forming a working condition feature vector of the fan; dividing the historical operating conditions of the fan; Identify the category of working conditions, and use the state feature vector to construct a benchmark model for online assessment of fan health according to the category of working conditions; input the feature vector of the current working condition into the preset training model to obtain the operating conditions of the current fan that belong to each working condition Working condition category probability and calculate the Mahalanobis distance between the current state feature vector and the benchmark model under each working condition; obtain the weighted average of the working condition category probability and the Mahalanobis distance from the benchmark model under each working condition and weighted average The value is transformed into a health index to describe the degree to which the fan operation status deviates from normal operation at the current moment. The invention can identify the deterioration process of the blower fan before the fault occurs in advance, and accurately evaluate the change of the health state of the blower fan during operation.
