Demand Analysis
At present, China's power shortage phenomenon is serious, transmission lines are often overloaded, towers, fixtures, insulators and other aging is becoming more and more serious, defects lead to higher temperatures, there is an urgent need for a monitoring, not only to see the video, but also to measure the temperature of towers, fixtures, wire clips, insulators and other temperature, to provide a basis for decision-making for the maintenance of transmission lines, but also to ensure the stable operation of the line.
Second, the principle of work
Overhead line image video monitoring device (dual-optical dome) to dual-optical infrared video and visible light video monitoring, including the main control unit, communication module, power supply module, dual-optical dome, wireless transmission unit; the use of solar energy and lithium battery power supply, the use of front-end dual-optical dome to capture the video data, through the 4G/5G/WIFI/OPGW fiber-optic network image/video data transmission to the monitoring center, to realize the transmission line tower equipment maintenance decision-making. Realize the transmission line tower equipment temperature monitoring timely detection of thermal defects and early warning, to realize the tower status, metal tools, insulator strings, conductors and channels and other details of the full range of status tracking, to protect the stable operation of the line.
Functional characteristics
1、with infrared dual-spectrum temperature monitoring of tower equipment to detect thermal defects and early warning;
2、support visible light and thermal imaging picture-in-picture and image fusion;
3、support for automatic generation, online view, a key to export the infrared inspection report function.
4、all-round intelligent dynamic monitoring: the head supports horizontal 360 ° rotation, vertical -90 ° ~ +90 ° rotation.
5、40 times optical zoom, to achieve the tower state, gold, insulator strings, wires and channels and other details of the full range of state tracking.
6、based on the industry depth of customized intelligent analysis algorithms, support for picture capture analysis, AI target recognition function.
7、Support line automatic patrol.
8、intelligent AI function support fog, intelligent exposure AE, intelligent focus AI.
9、Support real-time video monitoring functions, including PTZ control, zoom control, and night vision function.
10、support for automatic video patrol function, patrol mode can be configured to choose, the configuration includes running cycle, running time, patrol route and other information.
11、with dormant, timed capture, real-time video, 24-hour operation and other work modes to adapt to different work needs.
12、the device should be able to collect power supply voltage, mobile communication signal strength at the installation point and other information, data collection interval can be set to 1 minute.
13、through the monitoring center platform on the camera power on/off control, and the camera focal length, aperture, depth of field, image quality, PTZ orientation, preset position and other remote settings and control.
14、the device supports the South China Grid communication protocol, access to the power grid company intranet platform (support APN access capabilities).
15、continuous no light and no other power to supplement the conditions, split machine battery should be able to maintain the monitoring device for at least 15 days of normal operation.
16、such as the configuration of the alarm device, when the alarm comes into effect will be timely and automatically select the voice alarm mode for on-site alarm (can be remotely closed or open alarm and shouting function).
