Against the backdrop of escalating low-altitude threats, critical infrastructure such as power grid substations and oil production facilities are frequently subjected to intrusions by unauthorized drones. Building an efficient low-altitude defense barrier has become an essential industry requirement. By deeply integrating photoelectric turntables with anti-drone equipment, an integrated collaborative defense system is established. Using the photoelectric turntable as the core sensing unit and equipped with dual-band detection technology, it can accurately capture drone trajectories, identify targets, and transmit data synchronously around the clock, effectively addressing the pain points of traditional defenses and providing solid support for precise countermeasures. The anti-drone equipment relies on front-end sensing data and employs a combination of radio monitoring and navigation deception. It can be flexibly deployed in both fixed and mobile modes, while parameter optimization avoids interference with critical facilities and equipment, achieving integrated reconnaissance and strike capabilities around key areas such as substations. The system's collaborative operation achieves fully automated operation, adapting to complex all-weather scenarios, effectively resisting various illegal low-altitude drone threats, safeguarding the security of critical facilities, and contributing to the stable and orderly development of the industry.
