Cable life prediction system and method based on multiple environment parameters and variable weight

The embodiment of the invention discloses a cable life prediction system and method based on multiple environment parameters and variable weights, and the method comprises the steps: obtaining the cable type and layout environment of a to-be-predicted cable, and determining a plurality of life influence parameters and respective corresponding first weights based on the cable type and layout environment, when a linkage influence parameter with a linkage effect exists between the life influence parameters, linkage effect information of the linkage influence parameter is obtained, a first weight of the linkage influence parameter is adjusted based on the linkage effect information to obtain a second weight, and the standard service life of the cable to be predicted and a statistical value of the life influence parameter are obtained; and adjusting the standard service life according to the statistical value, the first weight of the service life influence parameter without the linkage effect and the second weight
