| description | The invention relates to an industrial equipment time sequence data compression and storage method and device. The method comprises the following steps: acquiring time sequence data collected at the current time; the deviation between the time sequence data and time sequence data recorded last time is calculated; when the deviation exceeds a dead zone range, recording the time sequence data; obtaining time sequence data recorded for multiple times, and counting the occurrence frequency of each characteristic value in the time sequence data recorded for multiple times; calculating the information entropy of each characteristic value according to the statistical frequency; according to the weight of the information entropy of each feature value in the total information entropy, obtaining the weight of each feature value; wherein the total information entropy is the sum of the information entropies of all the feature values; and by taking each feature value as a symbol, taking the weight of the feature value as |
