Description
Technical Field
[0001] This invention relates to the field of signal jamming equipment technology, specifically to a six-channel drone shielding backpack. Background Technology
[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 harms, such as the frequent occurrence of unauthorized drone flights in no-fly zones, or the use of drones to deliver poison.
[0003] While current drone technology is relatively mature, how to interfere with drone signals to protect against the risks of information leakage from drones is a technical problem that urgently needs to be solved. Summary of the Invention
[0004] To address the aforementioned technical problems, this invention provides a six-channel drone shielding backpack, which is easy to carry and widely applicable. It can be used to drive away and force landing unauthorized drones within visual range. Furthermore, once the drone is under control, its image transmission channel is cut off, preventing it from transmitting video, aerial photos, or receiving any commands from the ground controller, thus achieving protection of critical areas and preventing privacy breaches.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] This invention proposes a six-channel drone shielding backpack, comprising a shielding backpack body, and further comprising:
[0007] A cooling fan is installed on the side of the shielded backpack body and communicates with the interior of the shielded backpack body to release heat from inside the shielded backpack body; preferably, a main valve and a function indicator light are also provided at the cooling fan.
[0008] The backpack base plate is located inside the shielded backpack body and is connected to the shielded backpack body through mounting holes on the base plate. The backpack base plate houses a lithium battery, a microwave module, an ADRV9009 RF transceiver module, aluminum heat sinks, a power supply regulator module, and several uprights. These uprights provide stable support within the shielded backpack body, and the remaining modules are placed within this stable space. The microwave module and ADRV9009 RF transceiver module receive control signals transmitted by the drone remote controller and transmit interference signals to the omnidirectional antenna array to interfere with the drone control signals. The microwave module and ADRV9009 RF transceiver module can transmit interference signals in six different frequency bands.
[0009] An omnidirectional antenna array, which is fixed to the top of the shielded backpack body via a flanged RF conversion connector, is used to radiate interference signals.
[0010] As a preferred embodiment of the present invention, it also includes a backpack buckle and a combination lock. The backpack buckle is used for the stable connection between the backpack cover and the backpack, and the combination lock is used to encrypt the backpack buckle. The backpack buckle can only be opened after the combination lock is decoded, preventing it from being opened without cause and causing damage or loss of the main components inside the backpack.
[0011] As a preferred embodiment of the present invention, the lithium battery is fixed to the bottom plate of the backpack by sheet metal parts and screws, and the lithium battery supplies power to the microwave module and the ADRV9009 radio frequency transceiver module through a power supply voltage regulator module.
[0012] As a preferred embodiment of the present invention, the ADRV9009 RF transceiver module, the aluminum heat sink, and the microwave module are stacked and fixed on the bottom plate of the backpack, with the aluminum heat sink located between the ADRV9009 RF transceiver module and the microwave module; the power supply regulator module is fixed on the side of the aluminum heat sink.
[0013] As a preferred embodiment of the present invention, the number of aluminum heat dissipation teeth is not less than two sets.
[0014] As a preferred embodiment of the present invention, the maximum receiving range of the microwave module and the ADRV9009 RF transceiver module is 500-700 meters. The received control signal is analyzed to determine the current frequency band, and the microwave module and the ADRV9009 RF transceiver module are controlled to transmit interference signals that interfere with the frequency band.
[0015] As a preferred embodiment of the present invention, the UAV operates in a frequency band between 49MHz and 1100MHz. The microwave module and the ADRV9009 RF transceiver module include six interference signal generating devices placed inside them, generating interference signals in six different frequency bands: 49-500MHz, 500-600MHz, 600-630MHz, 630-89MHz, 89-980MHz, and 980MHz-1100MHz.
[0016] As a preferred embodiment of the present invention, the signal generated by the voltage-controlled oscillator is further amplified by a two-stage signal amplification circuit.
[0017] As a preferred embodiment of the present invention, the amplified signal is output through a radio frequency power transistor and connected to an omnidirectional antenna array via an SMA line.
[0018] As a preferred embodiment of the present invention, the side of the shielded backpack body is also provided with an air pressure balancing device. The air pressure balancing device balances the air pressure inside the shielded backpack body through an 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 airflow will flow through the air pressure valve to achieve the purpose of balancing the air pressure.
[0019] As a preferred embodiment of the present invention, the side of the shielded backpack body is also provided with a main switch valve, a function indicator light and a function interface, the function interface including a charging interface and an external power interface.
[0020] The beneficial effects of this invention are:
[0021] This invention provides a six-channel drone shielding backpack. While drone technology is becoming increasingly sophisticated, effective drone control has not yet met expectations. This invention targets unauthorized drone flights. The microwave module and ADRV9009 RF transceiver module can receive and identify the frequency band of the drone's received signals and emit sufficiently powerful interference signals of the same frequency band, preventing the drone from receiving control signals. The invention is simple to manufacture and highly versatile. Attached Figure Description

Detailed Implementation
[0025] 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 drawings described below are merely some embodiments of the present invention, and those skilled in the art can obtain other drawings based on these drawings without any creative effort.
[0026] like Figure 1As shown, the present invention provides a six-channel drone shielding backpack. The backpack design can free the user's hands and is convenient to move with the user, thus better exerting the shielding effect. It includes a shielding backpack body 1, a cooling fan 2, a backpack buckle 3, a password device 4, an omnidirectional antenna array 5, a backpack bottom plate 6, and an air pressure balancing device. The cooling fan 2 and the air pressure balancing device are fixed to the side of the shielded backpack body 1 with screws. The air pressure balancing device balances the air pressure inside and outside the shielded backpack body through an air pressure valve. The shell buckle 3 is located in the upper middle part of the side of the shielded backpack body 1. The shell buckle 3 is encrypted by the password device 4. The omnidirectional antenna array 5 is located at the top of the shielded backpack body 1 and is connected to the backpack through the radio frequency conversion connector 601. The radio frequency conversion connector is fixed to the backpack with screws. The backpack bottom plate 6 is placed inside the shielded backpack body 1. The backpack bottom plate 6 is connected to the shielded backpack body 1 through the mounting holes provided on the backpack bottom plate 6. The backpack bottom plate is equipped with a lithium battery 7, a microwave module 8, an ADRV9009 radio frequency transceiver module 9, aluminum heat dissipation teeth 10, a power supply voltage regulator module 11, and several uprights 12. The uprights 12 provide a stable space inside the shielded backpack body 1. The remaining modules are placed in the stable space. The microwave module 8 and the ADRV9009 radio frequency transceiver module 9 receive the control signals transmitted by the drone remote controller and transmit interference signals to the omnidirectional antenna array 5 to interfere with the drone control signals. The omnidirectional antenna array is connected to the ADRV9009 RF transceiver module and microwave module via RF converters and SMA cables.
[0027] In this embodiment, the shielded backpack body 1 can adopt a conventional backpack structure. The shell size can be designed according to actual conditions. The shell material is made of polypropylene, which has excellent heat resistance, chemical stability, and good mechanical properties. After the backpack is laid flat, the backpack cover and the backpack are stably connected by the backpack buckle 3. The backpack buckle is encrypted to prevent it from being opened without cause, which could damage or lose the main devices inside the backpack. The backpack buckle can only be opened after the password device is decoded. The shielded backpack body 1 is equipped with seven uprights 12. The bottom of the uprights is fixed to the bottom plate of the backpack with screws, and the top of the uprights 12 contacts the backpack shell to ensure that the main functional parts are not squeezed during use or transportation. The side air pressure balancing device balances the air pressure inside the shielded backpack body through air pressure valves. 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 airflow 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 high-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 base plate is the core structure of this invention. An ADRV9009 RF transceiver module 9 is mounted on the backpack base plate 6, and is fixed to the backpack base plate 6 with screws. Multiple interference signal generators are located inside the ADRV9009 RF transceiver module 9. The drone control signal is received through the omnidirectional antenna 5 and transmitted to the microwave module 8 and the ADRV9009 RF transceiver module 9, where the frequency band of the drone control signal is analyzed. The interference signal generators produce interference signals in the same frequency band as the drone control signal to affect the drone's reception of the control signal, thus achieving the purpose of shielding the drone. A lithium battery 7 is mounted on the backpack base plate 6 and is fixed to the backpack base plate by sheet metal parts 701 and screws. Its function is to provide sufficient power supply. The aluminum heat sink 10 is positioned above the ADRV9009 RF transceiver module 9 and connected to the backplate 6 with screws, ensuring it is securely attached to the ADRV9009 RF transceiver module 9 and in full contact with it. This ensures timely heat dissipation for the ADRV9009 RF transceiver module during operation. The microwave module 8 is positioned above the aluminum heat sink 10 and secured with screws. The power regulator module 11 is located on the side of the aluminum heat sink 10 and connected to it with screws. The power regulator module circuit is connected to a lithium battery, providing stable power to the ADRV9009 RF transceiver module and the microwave module. The omnidirectional antenna array 5, after being connected to the RF converter 601, is connected to the ADRV9009 RF transceiver module 9 via an SMA cable. This allows the high-power interference signals generated by the ADRV9009 RF transceiver module to be radiated outwards through the omnidirectional antenna array, thereby interfering with the UAV's received control signals.
[0029] In one specific embodiment of the present invention, the microwave module 8 and the ADRV9009 radio frequency transceiver module 9 receive signals through the omnidirectional antenna array 5. The built-in signal processing chip converts the signals into digital signals and performs spectrum analysis. In the spectrum analysis results, the frequency band of the UAV control signal is identified by the spectrum characteristics of the signal.
[0030] In one specific embodiment of the present invention, the microwave module 8 and the ADRV9009 RF transceiver module 9 can generate and transmit sufficiently powerful interference signals via an antenna to affect the remote controller's control of the drone. This device is mainly designed for drones operating in the 49MHz and 1100MHz frequency bands. For the corresponding frequency bands, the microwave module and the ADRV9009 RF transceiver module can transmit interference waves in six different frequency bands: 49-500MHz, 500-600MHz, 600-630MHz, 630-89MHz, 89-980MHz, and 980MHz-1100MHz. The working principle of the microwave module 8 and the ADRV9009 RF transceiver module is as follows: The module uses a V1015-9 voltage-controlled oscillator to generate interference signals in the corresponding frequency bands, which are then connected to the first-stage signal amplification circuit. The first stage uses a YG602020 broadband RF gain amplifier with a gain of 20dB, amplifying the original signal to 90 times its original value. The amplified signal is input into the second-stage signal amplification circuit, which uses an MW6S004NT1. This amplifies the signal by approximately 64 times, providing sufficient output power to interfere with the communication between the drone remote controller and the drone. Because 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, after two stages of amplification, is connected to an omnidirectional antenna array via a BLP14M8S60 (a 60W general-purpose LDMOS RF power transistor) to radiate and affect the communication between the drone and the remote controller. Detailed circuit design is omitted here; only key components are indicated. Changing the frequency only requires modifying some components; professionals can achieve the new frequency without additional effort.
[0031] In one specific embodiment of the present invention, the backpack is further equipped with a main switch valve 13, function indicator lights 14, a charging interface 15, and an external power interface 16. The main switch valve controls the power supply to the backpack. During use, simply opening the main switch valve enables the backpack to operate. The main switch valve, function indicator lights, charging interface, and external power interface are connected to the interior of the shielded backpack body 1 via mounting holes using aviation cables, fulfilling the functional requirements of the entire device. For example, a small mechanical or electronic switch can be used as the main valve. The mechanical switch controls the on / off of the lithium battery circuit through physical buttons, while the electronic switch is controlled by a chip, enabling more complex functions, such as long presses and short presses for different operations, such as short presses for on / off and long presses for restart. When the main switch valve is opened, the backpack's function indicator lights and various functional modules can operate normally, avoiding wasting power when not in use, thus achieving energy saving and circuit protection. The function indicator lights can be LED indicators, displaying different states according to different signals, such as detecting a drone control signal and activating the shielding mechanism. They can also use different colors and flashing frequencies to indicate other information, such as low battery. The charging port is used to charge the internal lithium battery 7, ensuring the backpack's power supply is maintained in various situations to meet its usage needs. The external power interface connects to the internal lithium battery 7 via a discharge circuit. This discharge circuit includes a protection circuit to ensure stable output voltage and current, and can also charge other devices via the external power interface.
[0032] This drone shielding backpack can significantly interfere with drones operating within the functional band, forcing them to land and cutting off their image transmission channels. The invention adopts a backpack structure and is not limited by the location of use.
[0033] The above examples are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of the present invention should be considered within the scope of protection of the present invention.
