Description

Technical Field

[0001] The present invention relates to the field of UAV countermeasures, and particularly to a UAV prevention and control countermeasure system and method. Background Art

[0002] UAVs are commonly used in fields such as detection, reconnaissance, and photography. A UAV countermeasure system refers to a system that controls UAVs when they reach an uncontrollable state. Nowadays, "unauthorized flights" are prevalent, and a set of system devices are needed to control illegally flying UAVs. Anti-UAV technology refers to a device that detects, identifies, interferes with, deceives, controls, or even destroys UAVs. The anti-UAV system consists of four main subsystems and modules: a search system, an optical tracking system, a radio frequency interference system, and a display and control unit. Among them, the search system completes the monitoring and position indication functions of low-altitude targets in the mission area and is composed of a search radar and a radio spectrum monitoring system. The two types of search systems can be used independently or in combination according to the environment to improve detection performance. Common countermeasure methods include radio interference, net capture technology, hard damage technology, laser strike technology, etc. The following problem points to be solved are proposed for these technologies:

[0003] 1. The speed of UAVs is relatively fast, and there are often large differences in timeliness for fixed-point strikes, making it impossible to accurately and timely locate illegally flying UAVs.

[0004] 2. Conventional radio interference technologies often cannot strike some UAVs equipped with anti-countermeasure systems.

[0005] 3. The net capture method for capturing UAVs has very high technical requirements for accuracy. Often, when the first net bullet is fired and fails to capture, there is no time for a second capture, resulting in countermeasure failure. Summary of the Invention

[0019] Step 2: When the communication vehicle arrives at the target countermeasure area, the hydraulic system controls the first hydraulic rod to extend upward, so that the radar extends upward out of the front top plate, and then the radar can locate the target UAV;

[0020] Step 3: After the radar locates the target drone, the information is transmitted to the terminal processor.

[0025] 2. A drone prevention and control countermeasure system and method of the present invention combines radio jamming technology and net capturing technology for application. When the radio jamming deception fails, the communication server controls the hijacked drone to take off and combines the data fed back by the radar to the terminal processor to quickly fly the hijacked drone above the target drone. When the radar feedback data shows that the hijacked drone is located at a suitable position above the target drone, the terminal processor controls the communication server to send a net capturing signal to the hijacked drone, thereby solving the problem that conventional radio jamming technology often cannot attack some drones with anti-countermeasure systems.

[0026] 3. A drone prevention and control countermeasure system and method of the present invention improves the hit rate by improving the conventional land-launched net bomb to the air-launched net bomb of the hijacked drone. After the terminal processor controls the communication server to send a net capture signal to the hijacked drone, the net bomb primer is triggered, and the net bomb bracket wrapped with the capture net is launched out of the net bomb tube. Under the action of the torsion spring bolt, the third connecting rod, the second connecting rod and the first connecting rod will open the capture net so that the target drone can be accurately captured, which solves the problem that the conventional net capture method has very high technical requirements on accuracy in capturing drones, and often the first net bomb is launched but fails to capture, so there is no time for the second capture, resulting in countermeasure failure.

[0045] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0046] Among them, the accompanying drawings are only for illustrative purposes, showing only schematic diagrams, rather than physical diagrams, and should not be construed as a limitation of this patent; in order to better illustrate the embodiments of the present invention, some components in the accompanying drawings will be omitted, enlarged or reduced, and do not represent the dimensions of the actual product.

[0047] Refer to Figures 1 to 8An anti-drone prevention and countermeasure system and method as shown, including a target drone 8, and further including a carrier 1, a power system 2, a support system 3, a hydraulic mechanism 4, a radar communication system 5, a flipping mechanism 6, and a hijacking device 7. The power system 2, the support system 3, and the hydraulic mechanism 4 are respectively fixedly connected inside the carrier 1. The radar communication system 5 is fixedly connected to the hydraulic mechanism 4. The flipping mechanism 6 is hinged to the upper end of the carrier 1, and the hijacking device 7 for capturing the target drone 8 is placed inside the carrier 1.

[0048] The carrier 1 includes a communication vehicle 1a, a parking partition 1e, and a rear sliding roof 1f. One end of the communication vehicle 1a is provided with a carriage 1b. The top of one end of the carriage 1b is provided with a front roof 1c. A skylight opening 1d1 is opened on the front roof 1c. A first relief ramp 1d2 is opened at the bottom of the skylight opening 1d1. The skylight opening 1d1 is clamped with the flipping mechanism 6. The parking partition 1e is fixedly connected inside the carriage 1b. The hijacking device 7 is placed on the upper end of the parking partition 1e. The rear sliding roof 1f is slidably connected to the top of the other end of the carriage 1b. One end of the rear sliding roof 1f is provided with a tail door panel 1g. The tail door panel 1g is fixedly connected to the hydraulic mechanism 4. Setting the carrier 1 facilitates the transfer of this countermeasure system. The communication vehicle 1a can quickly reach the target countermeasure area according to the target countermeasure area, so that this countermeasure system can perform real-time positioning on the target drone 8 and then countermeasure. Setting the skylight opening 1d1 facilitates the hidden radar 5a to extend out of the front roof 1c to locate the target drone 8. The tail door panel 1g can slide out under the push of the second hydraulic rod 4d, so as to make room for the takeoff of the hijacking drone 7a.

[0049] The power system 2 includes a power distribution cabinet 2a. The power distribution cabinet 2a for providing driving power to the support system 3, the hydraulic mechanism 4, and the radar communication system 5 is fixedly installed inside the carriage 1b. An inverter is provided inside the power distribution cabinet 2a. The power distribution cabinet 2a is connected to each power device inside the carriage 1b through cables, so as to be able to provide power to the systems or devices that need power supply. A wireless charging device can be set on the parking partition 1e to charge the hijacking drone 7a.

[0050] The support system 3 includes a support base 3a, a buffer spring 3d, a buffer plate 3e, and a fixed cover 3g. The support base 3a is fixedly installed at the bottom inside the compartment 1b. An opening groove 3b is formed on the support base 3a. The buffer plate 3e is slidably connected inside the opening groove 3b. A spring base 3c is provided at the bottom of the opening groove 3b. A spring top seat 3f is provided at the bottom end of the buffer plate 3e. The two ends of the buffer spring 3d are respectively fixedly connected to the spring base 3c and the spring top seat 3f. The fixed cover 3g is fixedly connected to the upper end of the support base 3a and abuts against the buffer plate 3e. The support system 3 has a buffering effect to reduce the vibration caused by the bumps during the driving of the communication vehicle 1a to the radar 5a above, avoiding damage or accuracy reduction of the radar 5a due to vibration. Specifically, during the driving of the communication vehicle 1a, the buffer plate 3e shakes, which drives the buffer spring 3d to stretch or swing to absorb the vibration force.

[0051] The hydraulic mechanism 4 includes a hydraulic system 4a, a support plate 4c, two first hydraulic rods 4b, and a second hydraulic rod 4d. The hydraulic system 4a is fixedly installed inside the compartment 1b. The bottom ends of the two first hydraulic rods 4b are respectively fixedly installed on the upper end of the buffer plate 3e. The support plate 4c is fixedly installed on the upper ends of the two first hydraulic rods 4b. The two second hydraulic rods 4d are respectively fixedly installed on both side walls inside the compartment 1b, and the end parts of the two second hydraulic rods 4d are respectively fixedly connected to the tail door plate 1g. The hydraulic system 4a is connected to the first hydraulic rods 4b and the second hydraulic rod 4d through hydraulic pipelines, and the terminal processor 5c can control the hydraulic system 4a. When the communication vehicle 1a arrives at the target countermeasure area, the hydraulic system 4a controls the first hydraulic rod 4b to extend upward, so that the radar 5a extends upward out of the front top plate 1c, and then the radar 5a can locate the target UAV 8. The hydraulic system 4a controls the second hydraulic rod 4d to extend, so that the rear sliding top plate 1f slides backward in the compartment 1b, so that when the hijacking device 7 needs to be activated, the hijacking UAV 7a can take off to fly side by side and hijack the target UAV 8.

[0052] The radar communication system 5 includes a radar 5a, a communication server 5b, and a terminal processor 5c. The radar 5a is fixedly installed on the upper end of the support plate 4c. The communication server 5b and the terminal processor 5c are respectively fixedly installed inside the compartment 1b. Driven by the first hydraulic rod 4b, the radar 5a extends out of the front top plate 1c, and then the radar 5a can locate the target UAV 8. After the radar 5a locates the target UAV 8, it transmits the information to the terminal processor 5c. The terminal processor 5c controls the communication server 5b to first perform signal interference induction on the target UAV 8. If the communication server 5b successfully induces the target UAV 8, the countermeasure task is completed. If not, the terminal processor 5c controls the communication server 5b, and then the communication server 5b controls the hijacking UAV 7a to take off to fly side by side and hijack the target UAV 8.

[0053] The flipping mechanism 6 includes a flipping skylight 6a1, a slider 6c, a cover plate 6d, and a support rod 6e. The flipping skylight 6a1 is hinged to the front top plate 1c. Second relief ramps 6a2 and sliding grooves 6b are respectively formed at the bottom of the flipping skylight 6a1. The second relief ramps 6a2 are in abutting contact with the first relief ramps 1d2. The slider 6c is slidably installed in the sliding groove 6b. The cover plate 6d for preventing the slider 6c from falling off is fixedly installed at the port of the sliding groove 6b. The bottom end of the support rod 6e is fixedly installed on the support plate 4c, and the upper end of the support rod 6e is hinged to the slider 6c. The flipping mechanism 6 serves to seal and conceal the radar 5a. During non-operation, both the flipping mechanism 6 and the rear sliding top plate 1f remain in a normally closed state to prevent the system from being easily detected. When the communication vehicle 1a arrives at the target countermeasure area, the first hydraulic rod 4b pushes upward, causing the support rod 6e to move upward. The support rod 6e drives the slider 6c to slide in the sliding groove 6b, thereby causing the flipping skylight 6a1 to rotate upward and open to make way for the radar 5a. When the task is completed, the first hydraulic rod 4b retracts downward, thereby driving the flipping skylight 6a1 to close.

[0054] The hijacking device 7 includes a hijacking drone 7a, a net cartridge 7b, a net cartridge support 7e, and three compression springs 7d2. The net cartridge 7b is fixedly installed at the bottom of the hijacking drone 7a. A primer interface 7c is provided at the bottom of the cavity of the net cartridge 7b. Three spring grooves 7d1 are formed on the net cartridge 7b. The top ends of the three compression springs 7d2 are respectively fixedly installed in the three spring grooves 7d1. The net cartridge support 7e is snap-fitted with the net cartridge 7b. When the communication server 5b fails to successfully interfere with and induce the target drone 8 through signal jamming, the terminal processor 5c controls the communication server 5b, which in turn controls the hijacking drone 7a to take off and fly alongside the target drone 8 for hijacking.

[0055] The net bullet bracket 7e includes a base 7e1, three first connecting rods 7e3, a second connecting rod 7e4, a third connecting rod 7e5 and a plurality of torsion spring bolts 7e7. The base 7e1 is clamped in the primer interface 7c, a primer 7e2 is provided at one end of the base 7e1, one end of the three first connecting rods 7e3 are respectively hinged on the base 7e1 through three torsion spring bolts 7e7, one end of the three second connecting rods 7e4 are respectively hinged to the other end of the three first connecting rods 7e3 through three torsion spring bolts 7e7, one end of the three third connecting rods 7e5 are respectively hinged to the other end of the three second connecting rods 7e4 through three torsion spring bolts 7e7, and the other end of each third connecting rod 7e5 is provided with a resistance cylinder 7e6, the three resistance cylinders 7e6 are respectively slidably connected in the three spring grooves 7d1, and the three resistance cylinders 7e6 are respectively in resistance with the three compression springs 7d2. The net bomb bracket 7e is wrapped with a capture net. When the communication server 5b fails to induce signal interference on the target UAV 8, the communication server 5b controls the hijacked UAV 7a to take off and combines the data fed back by the radar 5a to the terminal processor 5c to quickly fly the hijacked UAV 7a above the target UAV 8. When the radar 5a feedback data shows that the hijacked UAV 7a is located at a suitable position above the target UAV 8, the terminal processor 5c controls the communication server 5b to send a net capture signal to the hijacked UAV 7a, thereby triggering the primer 7e2, and the net bomb bracket 7e wrapped with the capture net is launched out of the net bomb tube 7b. Under the action of the torsion spring bolt 7e7, the third connecting rod 7e5, the second connecting rod 7e4 and the first connecting rod 7e3 will open the capture net so that the target UAV 8 can be accurately captured.

[0056] A method for a drone prevention and control countermeasure system comprises the following steps:

[0057] Step 1: quickly move the communication vehicle 1a to the target countermeasure area so that the countermeasure system can locate the target drone 8 in real time and then countermeasure it;

[0058] Step 2: When the communication vehicle 1a arrives at the target countermeasure area, the hydraulic system 4a controls the first hydraulic rod 4b to extend upward, so that the radar 5a extends upward from the front top plate 1c, and then the radar 5a can locate the target drone 8;

[0059] Step 3: After the radar 5a locates the target UAV 8, the information is transmitted to the terminal processor 5c. The terminal processor 5c controls the communication server 5b to first perform signal interference induction on the target UAV 8. If the communication server 5b successfully induces the target UAV 8, the countermeasure mission is completed;

[0060] Step 4: When the communication server 5b fails to induce the signal interference to the target UAV 8, the terminal processor 5c controls the communication server 5b to make the communication server 5b control the hijacking UAV 7a to take off and hijack the target UAV 8;

[0061] Step 5: When the communication server 5b fails to induce signal interference on the target UAV 8, the communication server 5b controls the hijacked UAV 7a to take off and combines the data fed back by the radar 5a to the terminal processor 5c to quickly fly the hijacked UAV 7a above the target UAV 8. When the radar 5a feedback data shows that the hijacked UAV 7a is located at a suitable position above the target UAV 8, the terminal processor 5c controls the communication server 5b to send a net capture signal to the hijacked UAV 7a, thereby triggering the primer 7e2, and the net bomb bracket 7e wrapped with the capture net is launched out of the net bomb tube 7b. Under the action of the torsion spring bolt 7e7, the third connecting rod 7e5, the second connecting rod 7e4 and the first connecting rod 7e3 will open the capture net so that the target UAV 8 can be accurately captured.

[0062] Working principle: The carrier 1 is set to facilitate the transfer of this countermeasure system. The communication vehicle 1a can quickly reach the target countermeasure area according to the target countermeasure area, so that this countermeasure system can perform real-time positioning on the target UAV 8 and then counter it. The skylight opening 1d1 is set to facilitate the hidden radar 5a to extend out of the front roof panel 1c to position the target UAV 8. The tail door panel 1g can slide out under the push of the second hydraulic rod 4d, so as to make room for the hijacking UAV 7a to take off. An inverter is provided in the power distribution cabinet 2a. The power distribution cabinet 2a is connected to each power device in the carriage 1b through cables, so as to provide power for the systems or devices that need power supply. A wireless charging device can be set on the shutdown partition 1e to charge the hijacking UAV 7a. The support system 3 has a buffering effect to reduce the vibration caused by the bumps during the driving of the communication vehicle 1a to the radar 5a above, and avoid damage or reduced accuracy of the radar 5a due to vibration. Specifically, when the communication vehicle 1a is driving, the buffer plate 3e shakes, and then drives the buffer spring 3d to stretch or swing to absorb the vibration force. The hydraulic system 4a is connected to the first hydraulic rod 4b and the second hydraulic rod 4d through hydraulic pipelines, and the terminal processor 5c can control the hydraulic system 4a. After the communication vehicle 1a arrives at the target countermeasure area, the hydraulic system 4a controls the first hydraulic rod 4b to extend upward, so that the radar 5a extends out of the front roof panel 1c, and then the radar 5a can position the target UAV 8. The hydraulic system 4a controls the second hydraulic rod 4d to extend, so that the rear sliding roof panel 1f slides backward in the carriage 1b, so that when the hijacking device 7 needs to be started, the hijacking UAV 7a can take off to fly side by side with the target UAV 8 for hijacking. The radar 5a extends out of the front roof panel 1c under the drive of the first hydraulic rod 4b, and then the radar 5a can position the target UAV 8. After the radar 5a positions the target UAV 8, the information is transmitted to the terminal processor 5c. The terminal processor 5c controls the communication server 5b to first perform signal interference induction on the target UAV 8. If the communication server 5b successfully induces the target UAV 8, the countermeasure task is completed. If not, the terminal processor 5c controls the communication server 5b, and then the communication server 5b controls the hijacking UAV 7a to take off to fly side by side with the target UAV 8 for hijacking. The flipping mechanism 6 plays a role in sealing and hiding the radar 5a. During the non-operation process, both the flipping mechanism 6 and the rear sliding roof panel 1f remain in the normally closed state to prevent this system from being easily detected. After the communication vehicle 1a arrives at the target countermeasure area, the first hydraulic rod 4b pushes upward, causing the support rod 6e to move upward. The support rod 6e drives the slider 6c to slide in the chute 6b, and then the flipping skylight 6a1 rotates upward to open to make room for the radar 5a. When the task is completed, the first hydraulic rod 4b retracts downward, driving the flipping skylight 6a1 to close. When the communication server 5b fails to perform signal interference induction on the target UAV 8 first, the terminal processor 5c controls the communication server 5b, and then the communication server 5b controls the hijacking UAV 7a to take off to fly side by side with the target UAV 8 for hijacking.The net bomb bracket 7e is wrapped with a capture net. When the communication server 5b fails to induce signal interference on the target UAV 8, the communication server 5b controls the hijacked UAV 7a to take off and combines the data fed back by the radar 5a to the terminal processor 5c to quickly fly the hijacked UAV 7a above the target UAV 8. When the radar 5a feedback data shows that the hijacked UAV 7a is located at a suitable position above the target UAV 8, the terminal processor 5c controls the communication server 5b to send a net capture signal to the hijacked UAV 7a, thereby triggering the primer 7e2, and the net bomb bracket 7e wrapped with the capture net is launched out of the net bomb tube 7b. Under the action of the torsion spring bolt 7e7, the third connecting rod 7e5, the second connecting rod 7e4 and the first connecting rod 7e3 will open the capture net so that the target UAV 8 can be accurately captured.
