Abstract

The invention provides a power transmission line hidden danger detection method and system. The method comprises the steps of: extracting the basic features of a monitoring image, and searching a candidate region; respectively detecting construction machinery, a smoke and fire target and a ground wire foreign matter on the candidate area; combining the detection results to obtain a detection conclusion. Based on the fact that power transmission line channel hidden danger targets are diverse and the characteristics of three types of targets including construction machinery, fireworks and groundwire foreign matters, the recognition performance of a Cascade R-CNN frame regression method, a Faster R-CNN frame regression method and an FCOS frame regression method on each type of hidden dangertargets is tested respectively, reference detection algorithms of the three types of hidden danger targets are determined on the basis, each algorithm is optimized in a targeted mode, and compared with a traditional power transmission line channel hidden danger target detection algorithm adopting a single universal algorithm, the recognition accuracy of all kinds of hidden danger targets is improved. On the basis of ensuring the target detection precision, the detection speed is improved, and the hardware power consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of comprehensive protection of transmission lines, in particular to a method and system for detecting hidden dangers of transmission lines. Background technique [0002] With the large-scale installation of transmission line channel monitoring devices, line inspectors can obtain real-time transmission line channel live conditions without leaving home, which reduces the workload of out-of-the-box inspections and reduces the cost of transmission line operation and maintenance. Shandong Power Grid has installed 55,000 sets of visual monitoring devices for transmission line channels in the province, generating about 2.4 million pictures every day. In order to reduce the workload of manual image reading, artificial intelligence image recognition technology is applied to the automatic identification of hidden dangers outside the transmission line channel. Greatly reduced the number of manual reading required. [...
