Description

Technical Field

[0001] This invention relates to a countermeasure system and method for the safe transportation of large-item logistics drones, belonging to the field of drone protection technology. Background Technology

[0002] Currently, cargo drones are primarily used for cargo transportation operations via airborne navigation and ground control systems. However, in practice, current cargo drone equipment often lacks necessary protective capabilities, particularly in dealing with interference from ground or airborne wireless signals, as well as interference and obstruction from smaller drones. There are often no effective countermeasures, posing a significant safety hazard to cargo drone operations. Currently, there is no professional and effective solution to this problem.

[0003] To address this issue, there is an urgent need to develop a novel countermeasure system and method for the safe transportation of large-item logistics drones, in order to meet the needs of practical work. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a countermeasure system and method for the safe transportation of large-item logistics drones. This invention features a high degree of system integration, modularity, and automation. On the one hand, it can effectively meet the needs of various types of drones with different structures, offering good flexibility and versatility. On the other hand, during operation, it can effectively detect and investigate factors that threaten the safety of drone system operation and effectively suppress and respond to them, thereby improving the operational safety of transport drones.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] A countermeasure system for the safe transportation of large-item logistics drones includes a guide chute, a countermeasure radio frequency antenna group, an antenna radome, a target identification unit, an interference signal generator, and a drive circuit. The guide chute is connected to the outer side of the transport drone and is distributed parallel to the axis of the transport drone's fuselage. At least one antenna radome is slidably connected to the outer side of the transport drone via the guide chute and is distributed parallel to it. The countermeasure radio frequency antenna group is located inside the antenna radome and is electrically connected to the interference signal generator. The number of target identification units is the same as the number of antenna radomes. Each target identification unit is connected to the guide chute, and each target identification unit and one antenna radome constitute a countermeasure group. The interference signal generator and the drive circuit are both located inside the transport drone. The interference signal generator is electrically connected to the countermeasure radio frequency antenna group, the target identification unit, and the drive circuit. The drive circuit is also electrically connected to the target identification unit and the flight control system of the transport drone.

[0007] Furthermore, the radome includes a polymer faceplate, a polymer base, an electromagnetic shielding mesh, a semiconductor cooling mechanism, an alloy frame, and an assembly base. The polymer faceplate and polymer base both have a U-shaped cross-section. The polymer faceplate covers the upper surface of the polymer base and forms a sealed cavity. The counter-RF antenna assembly is located within the assembly cavity and connected to the polymer base via the assembly base. The counter-RF antenna assembly is coaxially distributed with the assembly cavity. The bottom of the polymer base has several assembly slots, each for... Each slot is equipped with a semiconductor cooling mechanism, and the heat dissipation end of the semiconductor cooling mechanism is located outside the polymer base. The electromagnetic shielding mesh is embedded in the inner surface of the polymer face mask and the polymer base. After the polymer face mask and the polymer base are closed, the electromagnetic shielding mesh inside the polymer face mask and the polymer base are electrically connected to each other. The electromagnetic shielding mesh of the polymer base is electrically connected to the drive circuit through wires. The alloy keel is a frame structure coaxially distributed with the polymer base, covering the bottom of the polymer base and slidingly connected to the guide groove.

[0008] Furthermore, the radome has a cross-section that is rectangular, U-shaped, or saddle-shaped. When the radome is U-shaped or saddle-shaped, the radome covers the outside of the transport drone's fuselage, and the counter-radio frequency antenna assembly inside the radome also covers the outside of the transport drone's fuselage.

[0009] Furthermore, the target identification unit includes a support base, a support bracket, an optoelectronic camera unit, a passive detection radar antenna, and a passive detection radar main unit. The support base is a closed cavity structure with a rectangular cross-section, and its outer surface is slidably connected to a guide groove. The optoelectronic camera unit is coaxially distributed and connected to the upper surface of the support base via a turntable mechanism. There are at least three support brackets, evenly distributed around the axis of the support base and hinged to the outer surface of the support base via a flipping mechanism. The support bracket plate surface forms an angle of 0°–90° with the axis of the support base. At the same time, each support bracket has a passive detection radar antenna on its upper and lower surfaces, and each passive detection radar antenna is electrically connected to the passive detection radar main unit. The passive detection radar main unit is located inside the support base, and the passive detection radar main unit, optoelectronic camera unit, flipping mechanism, and turntable mechanism are all electrically connected to the drive circuit. The passive detection radar main unit is also electrically connected to an interference signal generator.

[0010] Furthermore, the photoelectric imaging unit includes a carrier shell, a lidar, a microwave radar, a visible light / low light camera, an infrared thermal imager, a gyroscope stabilizer, and an optical lens. The carrier shell is a closed cavity structure, and its rear end is connected to the turntable mechanism of the carrier base through the gyroscope stabilizer. The carrier shell has several independent working chambers. The lidar, microwave radar, visible light / low light camera, and infrared thermal imager are each located in an independent working chamber and are coaxially distributed with the working chamber. Optical lenses are provided at the front end of the working chambers corresponding to the lidar, visible light / low light camera, and infrared thermal imager. The lidar, microwave radar, visible light / low light camera, infrared thermal imager, and gyroscope stabilizer are all electrically connected to an interference signal generator and a drive circuit.

[0011] Furthermore, the driving circuit is an FPGA-based circuit system.

[0012] A countermeasure method for a system designed to counter the secure transport of large-item logistics drones includes the following steps:

[0013] S1, System Configuration: First, based on the structure of the transport drone's fuselage, set the structure and quantity of the counter-radio frequency antenna group, radome, and target identification unit. Then, on the one hand, install the interference signal generator and drive circuit inside the transport drone's fuselage, and on the other hand, install the counter-radio frequency antenna group, radome, and target identification unit outside the transport drone's fuselage. Finally, perform a power-on test on the assembled counter-radio frequency antenna group, target identification unit, interference signal generator, and drive circuit.

[0014] S2, Operation and Countermeasures: During the operation of the UAV, the target identification unit is driven to operate synchronously with the transport UAV. First, the target identification unit monitors and identifies potential targets in the surrounding airspace and on the ground that threaten the flight safety of the transport UAV along its flight path. Then, when it detects aircraft or radio interference signals that interfere with the normal operation of the transport UAV, it drives the interference signal generator to operate and uses the countermeasure radio frequency antenna group to suppress the interference signals of the aircraft and interference signals, thereby ensuring that the transport UAV can perform its flight mission normally.

[0015] The present invention has a high degree of system integration, modularity and automation. On the one hand, it can effectively meet the needs of various types of UAVs with different structures, and has good flexibility and versatility. On the other hand, during operation, it can effectively detect and investigate factors that threaten the safety of UAV system operation, and effectively suppress and respond to them, thereby achieving the goal of improving the safety of transport UAV operation.
