I. Requirements Analysis

With the acceleration of China's urbanization process, large-scale planning and construction projects across the country have led to compressed transmission line corridors. Illegal construction, tree planting, and unauthorized operations within transmission protection zones, along with sudden and seasonal external damage, pose significant threats to the safe operation of power lines. In some areas, isolated towers have even emerged, severely jeopardizing the secure and stable operation of the power grid. Therefore, our company has developed the "Overhead Line Image Online Monitoring Device (Dual-Camera Night Vision)" specifically to address these challenges. This highly specialized system is designed to monitor transmission line foundations for external damage prevention, severe ice storm conditions, construction site cranes, and vehicles crossing overhead lines.

II. Working Principle

Overhead Line Image Online Monitoring Device (Dual-Camera Night Vision) utilizes 4G/CDMA/GPRS technology from telecommunications providers. The system host digitizes and compresses data—including images from industrial high-definition cameras—then transmits it via 4G/GPRS/CDMA wireless networks or dedicated power grids to the monitoring center. Upon decoding the image signals at the center, real-time footage captured by the cameras is displayed on-screen. These images are displayed directly on screens, enabling real-time monitoring of potential safety hazards beneath transmission lines while also serving line inspection functions. Personnel can use computers at the monitoring center or smartphones/laptops in the field to check for unauthorized activities under transmission lines anytime, anywhere, significantly reducing the workload of inspection teams.

III. Features and Functions

1. Savings: Low equipment costs, low data charges, low maintenance expenses;

2. Fast: Quick installation: Only the camera unit and small solar panel are required, making setup simple and swift; Rapid system response: Images are delivered quickly from command issuance to reception.

3. More: More monitoring points: For the same cost, it can cover far more areas than video surveillance systems, effectively preventing external damage. More application scenarios: Monitoring offline construction sites, monitoring offline crane operations, monitoring offline tall vegetation, etc.

4. Ease of Use: User-friendly operation: As a B/S architecture system, it can be operated not only conventionally at a computer but also monitored anytime via WeChat. Ease of Maintenance: Designed from the outset to withstand harsh outdoor environments, the front-end equipment requires minimal maintenance and boasts a service life of 5-10 years.
