In order to strengthen the low-altitude security construction of large venues, Kongyu Technology proposed a fixed deployment plan within the control range. The deployment plan usually deploys the radio detection equipment in a higher area. When the black flying drone enters the control range, the radio performs passive detection to achieve high-precision detection and discovery of the drone. And the omnidirectional jamming equipment is linked to drive away the drone or make an emergency landing to ensure absolute safety within the control range. Support personnel can also carry portable jamming guns for counterattack patrols to protect key control areas. After discovering a drone, they can take corresponding measures to return the drone. This solution can realize real-time monitoring, analysis, pre-alarm and flexible disposal of drones that violate regulations or illegally enter low-altitude airspace, prevent major and malignant accidents in event venues, improve users' rapid response capabilities and emergency response capabilities, and form scientific management and efficient command mechanisms to ensure the continued safety and stability of sensitive airspace.
