Description

Technical Field

[0001] This invention relates to the field of drone countermeasures technology, specifically to a fully automatic drone detection device and its countermeasures system. Background Technology

[0002] In recent years, unmanned aerial vehicle (UAV) technology has matured and its application has become more widespread. As a result, control accidents and related safety issues caused by UAVs have become increasingly common. Therefore, the task of preventing and dealing with UAV-related accidents and terrorist attacks will be extremely challenging.

[0003] Currently, domestic drone countermeasure systems have begun to enter the market and have been applied in various industries. Some drone countermeasure systems are installed in mobile vehicles and can be flexibly deployed according to on-site needs. Most drone countermeasure systems operate within fixed locations and do not require dedicated drivers for long-distance travel, thus wasting manpower. Furthermore, conventional drone landing pads have poor constraint and positioning capabilities for drones. When vehicles need to be moved urgently, the drones must be manually stored and re-deployed before countermeasure operations can be carried out, resulting in low functionality for emergency situations. Summary of the Invention

[0004] To address these issues, the present invention provides a fully automatic unmanned aerial vehicle (UAV) detection device and its countermeasure system.

The limit strip 3 is engaged with the grooved structure at the lower end of the body 4, facilitating replacement of the body 4 and enabling rapid disassembly and assembly. This reduces maintenance time for a single body 4 and prevents situations where the vehicle cannot be dispatched. A door 7 is provided on the rear side of the body 4, and an unfolding plate 5 is rotatably connected to the left end of the body 4. The body 4 and the unfolding plate 5 are connected... The rotating connection is driven by a motor.
