Embodiment 1

[0034] This embodiment provides a sensor monitoring system for cable hot spots and damage tracking, including an infrared sensor, a visible light camera, a mechanical arm and a processor. The infrared sensor and the visible light camera are both installed on the mechanical arm and driven by the mechanical arm. The processor is respectively connected to the infrared sensor, the visible light camera and the robotic arm, such as figure 1 As shown, the data processing process of the processor includes the following steps:

[0035] Hot spot detection step S1: Obtain the infrared sensing data of the cable through the infrared sensor, construct an infrared image, judge the abnormal temperature point in the infrared image, and mark the coordinate position of the abnormal temperature point;

[0036] The acquisition of infrared images is specifically: converting the received infrared sensing data into electrical signals, and then converting them into digital signals after amplification,...

Abstract

The invention relates to a sensing monitoring method and system for cable hot spot and damage tracking. The system comprises an infrared sensor, a visible light camera, a mechanical arm and a processor, and the infrared sensor and the visible light camera are both installed on the mechanical arm. A data processing process of the processor comprises the steps of obtaining the infrared sensing data of a cable through the infrared sensor, judging the temperature abnormal points, and marking the coordinate positions; obtaining the visible light data of the cable through the visible light camera, determining a cable damage area, and marking a coordinate position; driving the mechanical arm to rotate, and obtaining the coordinate positions of the temperature abnormal points and the cable damage area; and according to the target with the highest temperature or the maximum damage range, driving the mechanical arm to conduct position adjustment, so that the target with the highest temperature or the maximum damage range is located within a monitoring range. Compared with the prior art, the sensing monitoring method and system has the advantages that the autonomous detection capability is realized, the manual operation is reduced, and the monitoring target can be tracked in real time.

Description

technical field [0001] The invention relates to the technical field of cable monitoring, in particular to a sensor monitoring method and system for cable hot spot and damage tracking. Background technique [0002] Currently common security monitoring equipment (infrared temperature measurement, camera) can be divided into: [0003] 1. For monitoring at a fixed location, the monitoring range is small, the angle cannot be changed, and the flexibility is low. [0004] 2. In the monitoring system with a pan-tilt, the camera can be rotated left and right or up and down, but the degree of automation is relatively low, and real-time online operation is required. In view of the large monitoring range, the existing ordinary monitoring equipment cannot be well utilized. [0005] The fault monitoring of cables is also mostly realized by monitoring schemes at fixed locations. For example, the invention with the publication number CN111707902A discloses a downhole cable fault detection ...
