Cable health state evaluation method and system

The cable health state evaluation method comprises the steps that evaluation indexes for evaluating the health state of a target cable are preset, the evaluation indexes comprise first-level indexes and second-level indexes, and the first-level indexes comprise an online monitoring index, a laying environment index, an offline detection index, an equipment information index and a daily inspection information index; obtaining evaluation index parameterized data in the target cable, and preprocessing the parameter data; according to a preprocessing result, combining a first preset weight to obtain logic, and constructing a comprehensive evaluation matrix; and determining the health state of the target cable according to the comprehensive evaluation matrix and the actual parameter data of the target cable in combination with the second comprehensive evaluation index calculation logic. According to the cable health state evaluation method and system provided by the invention, evaluation indexes in multiple aspect
