Precision is paramount in power line maintenance. Today, power maintenance personnel no longer need to traverse rugged terrain or endure extreme weather conditions. With just a few taps on their PC or mobile device to select indicators, they can clearly monitor every environmental dynamic along the transmission line corridor. This capability is delivered by the high-definition intelligent video/image condition monitoring device developed by Dingxin Smart Technology's R&D team—enabling full-process automatic identification of potential hazards along transmission line corridors, intelligent alerts, stable transmission, and image backhaul. It delivers grid security at your fingertips.
The image below shows a monitoring site. Upon opening the monitoring terminal, the screen clearly displays a large-scale greenhouse cultivation area beneath the transmission lines. What appears to be an ordinary farming zone actually conceals hidden threats to line safety. For overhead transmission lines, plastic sheeting from greenhouses poses a significant hazard that cannot be ignored. Particularly during strong winds, loose plastic fragments can become entangled with conductors over a wide area, triggering widespread power outages. Therefore, pre-installing online monitoring equipment is a prudent choice. Beyond foreign object hazards on conductors, construction activities below the lines and wildfires are also key monitoring targets.
In terms of hazard monitoring equipment, the advantages of high-definition intelligent video/image status monitoring devices supporting 24/7 continuous front-end monitoring are fully demonstrated. Equipped with industrial-grade high-definition cameras, these devices can capture real-time or scheduled snapshots of monitored transmission line corridors based on actual needs. The monitoring cycle can be shortened to as little as one minute per capture, significantly reducing monitoring gaps and ensuring no hazard detail is overlooked. Additionally, the device features starlight-level night vision with full-color imaging capability. It maintains full-color recording even in low-light conditions, delivering high-definition imaging day and night. During daylight hours, it captures intricate details with 8MP/16MP high-definition resolution, while at night, its 2MP night vision full-color lens clearly reconstructs the scene.
In terms of data transmission, the device features robust adaptability, enabling secure and stable delivery of captured images and short video data to the monitoring center via multiple transmission methods including 4G/5G/Wi-Fi wireless networks and dedicated power networks. It also supports VPN dedicated channels and encrypted transmission to ensure secure data communication. Power maintenance personnel no longer need to travel to the site. Instead, they can view real-time conditions along power lines anytime, anywhere via terminals such as computers or mobile phones, truly achieving "inspection at your fingertips." Furthermore, the device employs a low-power design with an online static power consumption of just 0.2W. It can selectively transmit only identified hazard images based on actual needs, effectively reducing communication costs and extending standby time. Paired with a solar and lithium-ion battery power system supporting wide voltage input, it operates reliably even in remote areas without signal coverage.
Notably, the device incorporates front-end network hardware AI algorithms, delivering robust intelligent recognition and early warning capabilities. It automatically identifies large construction machinery such as tower cranes, excavators, and lifts within line protection zones, promptly alerting to potential external construction hazards. It also accurately identifies various safety hazards including smoke, wildfires, foreign objects on conductors, and fishing activities. This eliminates the cumbersome need for manual screen monitoring. The device supports multiple installation methods—bracket mounting, wall mounting, suspended installation, and pole mounting—and is compatible with monitoring platforms of China Southern Power Grid, State Grid, and provincial power companies. It facilitates data sharing and system integration, providing power supply departments with comprehensive and accurate line status information.
