Spring, known as the kingdom of the wind, especially in the northern region, the power of the spring wind is not to be underestimated. Into April, from Xinjiang, Inner Mongolia to North China, Northeast, windy weather frequently attacked, transmission lines are faced with a number of foreign body hidden danger, not only threatens the safe and stable operation of the power grid, but also may cause safety accidents, to the social production and residents of the life of a serious impact.
First, the current situation of transmission line foreign body potential hazards
The transmission line foreign body potential hazards are many and wide, mainly focusing on the following aspects:
1, agricultural activities in the area: spring is the spring plowing period, farmers in the fields laid plastic film, reflective film and other materials, if not fixed, it is easy to be blown up by the wind, drifting down to the transmission line wires, towers.
2, construction sites: dust nets, waste plastics and other debris around the site, if not managed properly, can also become a potential threat to transmission lines.
3, human activities: the number of kite flying increased significantly in the spring, once the kite breaks hanging on the wire, it is very easy to cause line failure.
4, natural factors: spring trees grow vigorously, branches may be in contact with transmission lines, triggering short circuits. In addition, high winds may also cause hill fires, threatening the safety of transmission lines.
II. Response Program:Transmission Line Image video online monitoring device
This is a 360 ° rotation of the "head" of the "electronic eye", from all sides of the line for 24-hour monitoring, with automatic patrol function (such as 255 preset positions, 16 patrol lines), through intelligent identification and real-time warning. Through intelligent identification and real-time warning, it can discover and deal with the hidden danger of line foreign objects in time, and improve the level of line safety management.
Technical Advantages and Functional Features
1、High-definition panoramic monitoring
Our transmission line image video online monitoring device also called Transmission line AI video online monitoring device adopts high-definition camera and omnidirectional PTZ technology, with horizontal 360°, vertical ±90° omnidirectional rotation capability, supporting 30x optical zoom, realizing all-round and dead-angle-free capturing of equipment and channels. Illumination ≤ 0.001Lux/f1.2, night can also be shot in full color, real-time guarding the safe operation of the power grid.
2. Intelligent identification and early warning
Using front-end AI algorithms, it is able to quickly identify a variety of line hazards locally, such as foreign objects hanging (plastic bags, kites, etc.), construction machinery (cranes, excavators, pump trucks, etc.), hill fires, tree barriers, etc., and issue an early warning as soon as a hazard is detected, improving the efficiency of handling hazards.
3. Data transmission
The image data collected at the front end is transmitted wirelessly to the monitoring center through 4G/5G/WIFI, which can be accessed to the monitoring platform of the South China Grid, State Grid and other provincial power companies, supporting real-time viewing and historical data access. In addition, the operation and maintenance personnel can also remotely adjust the monitoring and shooting cycle, control the monitoring angle, focal length and other parameters, and fine patrol lines.
4、Self-powered
Adopt solar energy and lithium battery power supply, in the continuous no light and no other power supplement conditions, the battery can maintain the normal operation of the equipment for at least 15 days or more.
