Abstract

The invention provides a label-set-free cable trend identification method and device, and the method comprises the steps: determining a chip sequence of each transformer substation according to the number of transformer substations in a preset region, and a modulation signal carrying transformer substation information being injected into a cable for transmission through a grounding network; detecting and acquiring a signal carried by a to-be-detected cable through detection, demodulating and restoring an injected modulation signal, confirming station information at two ends of the to-be-detected cable based on correlation operation of a detection signal on the to-be-detected cable and the injected modulation signal, and identifying the trend of the cable. Through the scheme, the problem that an existing online cable identification method cannot identify the trend of the label-free cable is solved, the trend of the label-free cable can be accurately identified, the identification time is shortened, and the reliability of an identification result is guaranteed.

Description

Technical field [0001] The invention relates to the field of power cable detection, in particular to a method for identifying the direction of an unlabeled set cable. Background technique [0002] With the deepening of urbanization, the laying density of power cables is increasing, making the maintenance and management of cables particularly important. Correctly identifying the direction and attribution of cables is an important prerequisite for cable maintenance and maintenance, and its accuracy directly affects Affect the safety of people and equipment. [0003] For the identification of power cables, a lot of research has been done at home and abroad, which can be divided into offline identification and online identification: offline identification is mainly based on the pulse current method, which has high identification accuracy, but the pulse signal must be loaded after power failure To the cable; the online identification is mainly based on the electromagnetic coupling meth...
