Description

Technical Field

[0001] The present invention relates to the technical field of signal jammer equipment, and in particular to a six-channel unmanned aerial vehicle shielding backpack. Background Art

[0002] With the booming development of the drone market, drones are widely used in all aspects of social life. Inevitably, the use of drones has also brought some hazards, such as the frequent appearance of illegal drones in no-fly zones, or the use of drones to poison people.

[0003] Current drone technology is already relatively mature. How to interfere with drone signals to protect against hazards such as drone information leakage is a technical problem that needs to be solved urgently. Summary of the invention

[0004] In view of the above technical problems, the present invention provides a six-channel drone shielding backpack, which is easy to carry and has a wide range of applications. It can be used to drive away and force land illegal drones within the field of vision. After being controlled, the drone cuts off the image transmission channel and will not be able to transmit videos, aerial photos, or receive any instructions from the ground remote controller, thereby protecting key areas and preventing privacy leaks.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] The present invention proposes a six-channel UAV shielding backpack, including a shielding backpack body, and also includes:

[0007] A cooling fan is installed on the side of the shielding backpack body and is connected to the inside of the shielding backpack body to release the heat inside the shielding backpack body; preferably, a main switch valve and a function indicator light are also provided at the cooling fan.

[0008] The backpack bottom plate is placed inside the shielded backpack body, and the backpack bottom plate is connected to the shielded backpack body through a mounting hole set on the backpack bottom plate; a lithium battery, a microwave module, an ADRV9009 radio frequency transceiver module, aluminum heat dissipation teeth, a power supply voltage stabilizing module and a number of vertical poles are placed on the backpack bottom plate, and a stable space is obtained by supporting the shielded backpack body through the vertical poles. The remaining modules are placed in the stable space, and the control signal transmitted by the drone remote control is received through the microwave module and the ADRV9009 radio frequency transceiver module, and the interference signal that interferes with the drone control signal is transmitted to the omnidirectional antenna array. The microwave module and the ADRV9009 radio frequency transceiver module can transmit interference signals of six different bands.

[0009] The omnidirectional antenna array is fixed to the top of the shielding backpack body through a RF conversion connector with a flange, and is used to radiate interference signals.

[0010] Preferably, the present invention further includes a backpack buckle and a password device. The backpack buckle is used for the stable engagement of the backpack upper cover and the backpack. The password device is used to encrypt the backpack buckle. Only when the password device is decoded can the backpack buckle be opened, preventing the main devices inside the backpack from being damaged or lost due to being opened without reason.

[0011] Preferably, the lithium battery is fixed on the backpack bottom plate through sheet metal parts and screws, and the lithium battery powers the microwave module and the ADRV9009 radio frequency transceiver module through a power supply voltage stabilization module.

[0012] Preferably, the ADRV9009 radio frequency transceiver module, the aluminum heat dissipation teeth and the microwave module are stacked and fixed on the backpack bottom plate. The aluminum heat dissipation teeth are located between the ADRV9009 radio frequency transceiver module and the microwave module; the power supply voltage stabilization module is fixed on the side of the aluminum heat dissipation teeth.

[0013] Preferably, the number of the aluminum heat dissipation teeth is not less than 2 groups.

[0014] Preferably, the maximum receiving range of the microwave module and the ADRV9009 radio frequency transceiver module is 500 - 700 meters. The operating band is analyzed based on the received control signal, and the microwave module and the ADRV9009 radio frequency transceiver module are controlled to emit interference signals that have an interference effect on this band.

[0015] Preferably, the working frequency band of the unmanned aerial vehicle is between 49 MHz and 1100 MHz. The microwave module and the ADRV9009 radio frequency transceiver module include six interference signal generating devices placed inside them, generating six different bands of interference signals of 49 - 500 MHz, 500 - 600 MHz, 600 - 630 MHz, 630 - 89 MHz, 89 - 980 MHz, and 980 MHz - 1100 MHz.

[0016] Preferably, the signal generated by the voltage - controlled oscillator is further amplified through two - stage signal amplification circuits.

[0017] Preferably, the amplified signal is output through a radio frequency power transistor and connected to an omnidirectional antenna array through an SMA cable.

[0018] Preferably, a pneumatic balance device is also provided on the side of the shielded backpack body. The pneumatic balance device balances the air pressure inside the shielded backpack body through a pneumatic valve. When the air pressure difference between the inside and outside of the backpack exceeds the valve threshold, the corresponding pneumatic valve will open, and a unidirectional air flow will pass through the pneumatic valve to achieve the purpose of balancing the air pressure.

[0019] Preferably, a main switch valve, function indicator lights and function interfaces are also provided on the side of the shielded backpack body, and the function interfaces include a charging interface and an external power supply interface.

[0020] The beneficial effects of the present invention are as follows:

[0021] The present invention provides a six-channel drone shielding backpack. At present, drones are becoming increasingly mature, but the control of drones has not achieved the expected effect. When targeting unlicensed drones, the microwave module and ADRV9009 radio frequency transceiver module of the present invention can receive and identify the frequency band of the drone receiving signal and emit interference signals of the same frequency band with sufficient power, so that the drone cannot receive the control signal. The preparation is simple and the versatility is strong. Description of the Drawings

Detailed Embodiments

[0025] In order to more clearly illustrate the embodiments of the present invention or the technical solutions of the prior art, the present invention will be described in more detail below with reference to the accompanying drawings. Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0026] Such as Figure 1As shown, the present invention provides a six-channel UAV shielding backpack, the backpack style can free the user's hands and is convenient to move with the user to better play a shielding role, including a shielding backpack body 1, a cooling fan 2, a backpack lock 3, a password device 4, an omnidirectional antenna array 5, a backpack bottom plate 6, and an air pressure balance device. The cooling fan 2 and the air pressure balance device are placed on the side of the shielding backpack body 1 and fixed with screws. The air pressure balance device balances the air pressure inside and outside the shielding backpack body through the air pressure valve; the shell lock 3 is located in the middle and upper part of the side of the shielding backpack body 1, and the shell lock 3 is encrypted by the password device 4. The omnidirectional antenna array 5 is located at the top of the shielding backpack body 1 and is connected to the backpack through the radio frequency conversion connector 601, and the radio frequency conversion connector is fixed on the backpack by screws; the backpack bottom plate 6 is placed inside the shielding backpack body 1, and the backpack bottom plate 6 and the shielding backpack body 1 are connected through the mounting holes set on the backpack bottom plate 6; the backpack bottom plate is provided with a lithium battery 7, a microwave module 8, an ADRV9009 radio frequency transceiver module 9, an aluminum heat dissipation tooth 10, a power supply voltage stabilizing module 11 and a number of vertical poles 12, and a stable space is obtained by supporting the inside of the shielding backpack body 1 through the vertical poles 12, and the remaining modules are placed in the stable space, and the control signal transmitted by the drone remote controller is received through the microwave module 8 and the ADRV9009 radio frequency transceiver module 9, and the interference signal that interferes with the drone control signal is transmitted to the omnidirectional antenna array 5. The omnidirectional antenna array is connected to the ADRV9009 RF transceiver module and microwave module through an RF conversion connector and SMA cable.

[0027] In this embodiment, the shielding backpack body 1 can adopt a conventional backpack structure, and the shell size can be designed according to actual conditions. The shell material is made of polypropylene, which has the advantages of excellent heat resistance, chemical stability, good mechanical properties, etc. After the backpack is laid flat, the backpack cover and the backpack are stably connected through the backpack lock 3. The backpack lock is encrypted to prevent it from being opened without reason to cause damage or loss of the main device in the backpack. Only when the password device is decoded, the backpack lock can be opened. The shielding backpack body 1 is internally provided with seven vertical poles 12, the bottom of the vertical poles is fixed to the backpack bottom plate by screws, and the top of the vertical poles 12 is in contact with the backpack shell to ensure that the main functional part will not be squeezed during use or transportation. The air pressure balance device on the side balances the air pressure inside the shielding backpack body through the air pressure valve. When the air pressure difference between the inside and outside of the backpack exceeds the valve threshold, the corresponding air pressure valve will open, and a one-way air flow will flow through the air pressure valve to achieve the purpose of balancing the air pressure; the cooling fan adopts a PWM-controlled four-wire large air volume fan to ensure that the inside of the backpack will not overheat when the power amplifier module is working at full power.

[0028] like Figure 2As shown, the backpack bottom plate is the core structure of the present invention. An ADRV9009 radio frequency transceiver module 9 is placed on the backpack bottom plate 6. The ADRV9009 radio frequency transceiver module 9 is fixed to the backpack bottom plate 6 by screws, and there are multiple interference signal generating devices inside it. The drone control signal is received through the omnidirectional antenna 5, transmitted to the microwave module 8 and the ADRV9009 radio frequency transceiver module 9, and the band where the drone control signal is located is analyzed. The function of the interference signal generating device is to generate interference signals with the same frequency band as the drone control signal to affect the drone's reception of the control signal, achieving the purpose of shielding the drone. A lithium battery 7 is placed on the backpack bottom plate 6, and it is fixed to the backpack bottom plate by a sheet metal part 701 and screws. Its function is to provide a power supply with sufficient power. The aluminum heat dissipation teeth 10 are placed above the ADRV9009 radio frequency transceiver module 9 and are connected to the backplane bottom plate 6 by screws, so that it is fastened above the ADRV9009 radio frequency transceiver module 9, making full contact with the ADRV9009 radio frequency transceiver module 9 to ensure that the aluminum heat dissipation teeth 10 can dissipate heat from the ADRV9009 radio frequency transceiver module in a timely manner during operation. The microwave module 8 is placed above the aluminum heat dissipation teeth 10 and is fixed above the aluminum heat dissipation teeth 10 by screws. The power supply voltage stabilizing module 11 is placed on the side of the aluminum heat dissipation teeth 10, and it is connected to the aluminum heat dissipation teeth by screws. The power supply voltage stabilizing module is circuit-connected to the lithium battery, and its function is to provide stable power supply for the ADRV9009 radio frequency transceiver module and the microwave module. After the omnidirectional antenna array 5 is connected to the radio frequency conversion joint, the radio frequency conversion joint 601 is connected to the ADRV9009 radio frequency transceiver module 9 through an SMA connection line, so that the high-power interference signal generated by the ADRV9009 radio frequency transceiver module can be radiated outward through the omnidirectional antenna array to achieve the purpose of interfering with the drone's reception of the control signal.

[0029] In a specific implementation of the present invention, the microwave module 8 and the ADRV9009 radio frequency transceiver module 9 receive signals through the omnidirectional antenna array 5. Their built-in signal processing chips convert the signals into digital signals and perform spectrum analysis. In the spectrum analysis results, the frequency band where the drone control signal is located is identified through the spectral characteristics of the signals.

[0030] In a specific implementation of the present invention, the microwave module 8 and the ADRV9009 radio frequency transceiver module 9 can generate and transmit, through an antenna, interference signals with sufficiently high power to affect the control of the drone by the remote controller. This device is mainly targeted at drones with a working frequency band between 49 MHz and 1100 MHz. For the corresponding frequency bands, the microwave module and the ADRV9009 radio frequency transceiver module can emit interference waves in six different frequency bands: 49 - 500 MHz, 500 - 600 MHz, 600 - 630 MHz, 630 - 89 MHz, 89 - 980 MHz, and 980 MHz - 1100 MHz. The working principles of the microwave module 8 and the ADRV9009 radio frequency transceiver module are as follows: The module uses a voltage-controlled oscillator of model V1015-9 to generate interference signals in the corresponding frequency bands and is connected to the first-stage signal amplification circuit. The first stage uses a broadband radio frequency gain amplifier of model YG602020 with a gain of 20 dB, which amplifies the original signal to 90 times its original value. The amplified signal is input into the second-stage signal amplification circuit. The second stage uses MW6S004NT1, which further amplifies the signal by approximately 64 times on the original basis, so that the noise reaches a sufficient output power to affect the connection between the drone remote controller and the drone. Since the frequency band of the interference signal generated by the power amplifier module covers two common drone signal transmission frequency bands, this six-channel drone shielding backpack has a strong suppression effect on common drones. Finally, the signal amplified through two stages is connected to an omnidirectional antenna array through BLP14M8S60 (a 60W general-purpose LDMOS radio frequency power transistor) to achieve the radiation function and affect the connection between the drone and the remote controller. The detailed circuit design is omitted here, and only the key components are pointed out. If the frequency needs to be changed, only some of the components need to be changed, and professionals can obtain a new frequency without incurring labor costs.

[0031] In a specific implementation of the present invention, the backpack is also provided with a switch main valve 13, a function indicator light 14, a charging interface 15, an external power interface 16, etc. The switch main valve controls the on and off of the backpack power supply. During use, the backpack can be operated by simply opening the switch main valve. The switch main valve, the function indicator light, the charging interface, and the external power interface are connected to the inside of the shielded backpack body 1 through the mounting hole using an aviation line to meet the functional requirements of the whole machine. For example, a small mechanical or electronic switch is used as the main valve. The mechanical switch controls the on and off of the lithium battery circuit through a physical button, and the electronic switch is controlled by a chip to achieve more complex functions, such as long press and short press to achieve different operations, such as short press switch, long press restart, etc. When the switch main valve is turned on, the function indicator lights and various functional modules of the backpack can work normally, avoiding wasting electricity when not needed, and playing the role of energy saving and circuit protection. The function indicator light can be an LED indicator light, which displays different states according to different signals, such as detecting a drone control signal and starting a shielding mechanism, or it can prompt other information, such as insufficient power, through different colors and flashing frequencies. The charging interface is used to charge the internal lithium battery 7, which is convenient for maintaining the power supply of the backpack in various occasions to meet its use needs. The external power interface is connected to the lithium battery 7 in the backpack through a discharge circuit. The discharge circuit is provided with a protection circuit to ensure stable output voltage and current. Other devices can be charged through the external power interface.

[0032] The UAV shielding backpack can produce an obvious interference effect on UAVs operating within a functional band, causing the UAV to make an emergency landing and cutting off the image transmission channel of the UAV. The present invention adopts a backpack structure and is not restricted by the use site.

[0033] The above examples are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above examples, and many variations are possible. All variations that can be directly derived or associated with the contents disclosed by a person skilled in the art should be considered as the protection scope of the present invention.
