Method and device for determining cable state

The invention provides a cable state determination method and a cable state determination device. The method comprises the following steps: acquiring a plurality of groups of first concentration data and a plurality of groups of second concentration data at a plurality of continuous monitoring moments; and determining the health state of the cable of the trench body according to each group of first concentration data and each group of second concentration data. According to the method, the problem of low accuracy of determining the health state of the cable based on the power frequency electric signal in the prior art is solved. 本申请提供了一种电缆状态的确定方法和确定装置。该方法包括：在多个连续监测时刻下，获取多组第一浓度数据和多组第二浓度数据；根据各组第一浓度数据和各组第二浓度数据，确定沟体的电缆的健康状态。该方法解决了现有技术中基于工频的电信号确定电缆的健康状态的准确度较低的问题。
