Method and system for predicting residual life of oil filter element based on data analysis

The invention relates to the technical field of data processing, in particular to an oil filter element remaining life prediction method and system based on data analysis, and the method comprises the steps: obtaining the change mismatching of each piece of pressure difference data according to the correlation and difference between the pressure difference data and oil flow rate data of an oil filter element; clustering all the pressure difference data to obtain a target cluster, dividing a pressure difference fluctuation curve into an adjacent time sequence interval and a historical time sequence interval, calculating a distribution characteristic value of the pressure difference data in the target cluster in the adjacent time sequence interval, and obtaining the validity of each pressure difference data by combining the change mismatching of each pressure difference data; and obtaining the contribution degree of each differential pressure data and taking the contribution degree as the weight of the differen
