Embodiment 1

[0092] figure 1 It is a flow chart of a cable positioning method provided by Embodiment 1 of the present invention. This embodiment is applicable to the positioning of underground cables. The method can be executed by a cable positioning device, which can be controlled by software and / or hardware implementation, which can be configured in computer equipment, such as personal computers, servers, workstations, etc., specifically including the following steps:

[0093] S101. Drive the ground penetrating radar to detect the area where the cable is embedded, and obtain radar data.

[0094] In this embodiment, ground penetrating radar detection technology is used to locate and identify underground cables. Ground-penetrating radar judges the underground target body based on the analysis of the reflection waveform characteristics, and judges the spatial position, structure and distribution of the underground target body according to the travel time, amplitude and waveform of the ref...

Abstract

The embodiment of the invention provides a cable positioning method and device, computer equipment and a storage medium, and the method comprises the steps: driving a ground penetrating radar to carry out the detection of a region where a cable is pre-buried, and obtaining radar data; drawing geological image data for the underground space of the region according to the radar data; carrying out at least two levels of wavelet denoising on the geological image data; if wavelet denoising is completed, detecting inflection points in the geological image data; and connecting inflection points to the cable image data in sequence to represent the cable. According to the embodiment of the invention, an effective cable positioning scheme is provided for external force damage or aging fault supervision of the cable, cable identification under the condition that the cable is not touched is realized, the input labor cost is reduced, and the efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electric power engineering, and in particular to a cable positioning method, device, computer equipment and storage medium. Background technique [0002] Nowadays, with the rapid development of urban construction, after entering the modern society, due to the shortage of urban land, heavy traffic pressure, city appearance construction and other reasons, large cities generally use underground cable transmission methods. Especially in coastal areas, typhoons are frequent, and overhead lines are very vulnerable to injury. Buried cables perfectly resolve this problem. Compared with overhead lines, cables have the advantages of small footprint, reliable power transmission, and strong anti-interference ability. [0003] However, due to the buried nature of the cables, the cables are often damaged by external forces such as excavators. According to statistics, nearly 80% of urban powe...
