Abstract

The present invention discloses a method and system that are used to determine the service life endpoint and evaluate the current historical service life. The current historical service life evaluation method comprises: generating the load waveform of the driver according to the load information and movement position information of the transmission mechanism; obtaining the weighted coefficient of the current historical service life of the transmission mechanism according to said load waveform of the driver, and using the weighted coefficient to perform the weighted calculation on the current initial historical service life of the transmission mechanism to obtain the current historical service life of the transmission mechanism. In the method to determine the service life endpoint of the transmission mechanism, the initial value of the previous cumulated historical service life is preset; the current historical service life is added to the previous cumulated historical service life, and the resulting value is compare with the preset estimated service life of the transmission mechanism to determine whether this transmission mechanism reaches its service life endpoint. The technical solution of the present invention can increase the accuracy of the estimation made on the historical service life of the transmission mechanism.
