Power cable full life cycle tracking method and device

The invention provides a power cable full-life-cycle tracking method and device, and relates to the technical field of power cables, and the method comprises the steps: constructing a full-life-cycle monitoring database about the power cables; according to the full-life-cycle monitoring database, the operation state of the power cable put into use is obtained in real time; when the power cable breaks down, a first life stage of the power cable when the power cable breaks down is determined, and a second life stage corresponding to the fault is determined according to the full life cycle monitoring database; and when the first life stage is the same as the second life stage, predicting the fault occurrence condition of other power cables in the same batch as the power cable. According to the invention, by determining that other power cables which are produced, installed or used in the same batch as the corresponding faulty power cable possibly have the same or similar faults, the power cables which possibly ha
