Abstract

The invention discloses an unmanned patrol method and system for a transformer substation. The method comprises the steps that firstly, meter images, panel equipment images, pedestrian channel images, humidity, temperature and water immersion condition data are collected; then reading recognition is carried out on the meter type images through an SURF algorithm, state recognition is carried out on the panel type images through a mobilenet-v3 algorithm, pedestrian recognition is carried out on the pedestrian channel images through a yolov3 model, work garment and safety helmets of pedestrians are recognized through the mobilenet-v3 algorithm, and humidity, temperature and water immersion condition data are compared with preset values; when the recognition result does not accord with a preset value, alarm processing is carried out; and finally, based on a preset transformer evaluation criterion, generating an inspection report according to an recognition result, and sending the inspection report to operation and maintenance personnel. Therefore, the technical problems of single scene and single function of the existing patrol technology are solved.

Description

technical field

[0001] The present application relates to the technical field of electric power operation and maintenance, and in particular to an unmanned substation inspection method and system. Background technique

[0002] With the rapid development of technologies such as drones and intelligent robots, the functional complexity of drones and robots is increasing. In the construction of smart substations, the use of drones and robots for unmanned inspections has become a key to the construction of smart substations. content. However, the existing drone or robot inspection technology is only aimed at certain specific scenarios or designated types of equipment, such as drone inspection for a 500kv transmission line, such as robot intelligent recognition for substation meters, panels and indicators , the equipment is single, the scene and lines are fixed, and it is relatively simple to implement. However, for the full coverage of substations without inspection, due to the ...
