Zusammenfassung:The invention discloses an electric screw press service life prediction method and system based on data fusion. The method comprises the steps that S1, historical operation data of key components of an electric screw press in the operation process are collected; s2, preprocessing the historical operation data to generate a sample data set; s3, inputting the historical operation data subjected to final dimension reduction and filling into a time sequence model in a mode of parallel fusion of a long-short-term memory model and the time sequence model, obtaining a first sequence of continuous residual life prediction values at a future time point and a corresponding confidence interval, constructing the long-short-term memory model, and obtaining a second sequence of continuous residual life prediction values at the future time point; training the prediction model according to the sample data set; and S4, acquiring real-time operation data, inputting the real-time data into the prediction model to obtain a life
