To strengthen the low altitude security construction of large venues, Kongyu Technology proposes to adopt a fixed deployment plan within the control range. The deployment plan usually deploys radio detection equipment in higher areas. When black flying drones enter the control range, the radio performs passive detection to achieve high-precision detection and discovery of the drones. And coordinate with omnidirectional jamming equipment to carry out disposal measures such as driving away or forced landing of unmanned aerial vehicles, ensuring safety within the control range. Security personnel can also carry portable jamming guns for countermeasure patrols, protect key control areas, and take corresponding disposal measures upon discovering drones to allow them to return. This plan can achieve real-time monitoring, analysis, warning, and flexible disposal of unmanned aerial vehicles that violate regulations and illegally enter low altitude airspace, prevent major malignant accidents from occurring in event venues, enhance users' rapid response capabilities and emergency response capabilities, form a new mechanism for scientific management and efficient command, and ensure the continuous safety and stability of sensitive airspace.
