The distance between power transmission towers is relatively large, and across these lengthy conductor spans, complex situations frequently arise. For instance, accidents involving external forces—such as construction vehicle cranes accidentally snagging conductors or excavators severing cables—still occur from time to time. These incidents not only cause circuit tripping and power outages but may also lead to equipment damage and personal injury. Manual surveillance is incomplete and prone to oversight due to fatigue. Conventional video monitoring systems are susceptible to weather conditions and obstructions, creating blind spots. While they serve a purpose, they cannot eliminate risks entirely.

To more effectively guard against threats to transmission lines from external forces such as construction vehicles, Dingxin Smart Technology Co., Ltd. has launched a lightweight version of its Line Guardian—the Intelligent External Damage Prevention Device—specifically the Transmission Line Millimeter-Wave Radar External Damage Prevention Online Monitoring Device (Model DX-WPS100-JG3).

As a lightweight "Line Guardian," The intelligent anti-external damage devicedraws upon the core characteristic of "short-wavelength electromagnetic waves." Its emitted signals operate at millimeter-scale wavelengths. This physical property addresses the pain points of traditional monitoring equipment—bulky size, high power consumption, and insufficient accuracy—laying the foundation for adapting the device to outdoor tower scenarios and enabling effective monitoring.

Its operational logic is straightforward, integrating channel visualization, standardized sensor connectivity, AI edge computing, radar ranging, and ultra-low power consumption. It pinpoints potential hazards and safety distances with millimeter-level precision, employing dual "radar + image" verification to ensure reliable alerts. This system detects the distance, angle, height, and speed of objects within the measurement area, enhancing recognition accuracy. It assists line inspectors in promptly identifying external threats such as construction machinery trespassing or foreign objects encroaching on boundaries, compressing hazard response times from "hours" to "minutes" and establishing an intelligent defense for grid safety. or foreign object intrusion. This reduces hazard response time from hours to minutes, fortifying an intelligent defense line for secure power grid operations.
