Power transmission line high-definition video monitoring method and system based on 5G communication

Abstract

The invention discloses a power transmission line high-definition video monitoring method and system based on 5G communication, and the method comprises the steps: obtaining a monitored image of a power transmission line, and extracting the feature points of the monitored image of the obtained monitored image through employing an SIFT algorithm; respectively matching the feature points of the monitoring image with the feature points of each image in the fuzzy space generated by the clear image, and judging the matching similarity between the feature points of the monitoring image and the feature points of each image in the fuzzy space generated by the clear image; if the matching similarity between the feature points of the monitoring image and the feature points of each image in the blurred space generated by the clear image is higher than a preset threshold, sending the monitoring image to a monitoring center. According to the invention, the acquired image is processed, so the image quality of the image transmitted to the monitoring center is improved.

Description

technical field [0001] The invention relates to the technical field of power transmission line monitoring, in particular to a method and system for high-definition video monitoring of power transmission lines based on 5G communication. Background technique [0002] With the rapid development of social economy, all walks of life have put forward higher requirements for the quality and quantity of power supply. Due to the uncertainty of the environment of the transmission line in the power grid, whether the line operation is safe has become a part of the reliability of the power grid. an important indicator. [0003] Since transmission lines extend tens or even hundreds of kilometers vertically and horizontally, they are in different environments. Therefore, the high-voltage transmission line is greatly affected by the geographical environment and climate, and the annual power outage accidents in the power grid are mainly caused by line accidents. [0004] In the past, trans...

Problems solved by technology

[0004] In the past, transmission line inspections mainly relied on periodic inspections by operation and maintenance personnel. Although hidden dangers in equipment can be found, due to their own limitations, they lack detection of special environments and climates, and they cannot timely grasp changes in external forces in line corridors during the vacuum period of inspection cycles. It is very easy to have a line accident due to lack of monitoring before the next inspection. Therefore, the application of the line online monitoring system is born. It uses wireless (GSM / GPRS / CDMA) transmission methods to monitor the environment, temperature, humidity, and wind speed of the transmission line. , wind direction, leakage current, icing, conductor temperature, wind deflection, sag, galloping, insulator pollution, surrounding construction conditions, tower tilt and other parameters are monitored in real time, and early warning of abnormal conditions of the line is provided. By monitoring the effective parameters of the line , can improve the management level of the safe and economical operation of transmission lines, and provide the necessary degree for the condition maintenance work of transmission lines

[0005] However, due to the interference of the external environment, such as wind and sand, heavy fog and other weather, the camera of the current transmission line online monitoring system causes the image collected by the camera to be blurred, and the blurred image is transmitted to the monitoring system through the online monitoring system. After the center, it also makes the picture of the monitoring center unclear, which may easily lead to misjudgment by the staff
