Background Art

[0002] Unmanned Aerial Vehicle (UAV) is an unmanned aircraft controlled by radio remote control equipment and self-contained program control devices. It is widely used in many fields such as aerial photography, agricultural supervision, plant protection, material transportation, wildlife observation, surveying and mapping, news reporting, etc., bringing great convenience and economic benefits to all walks of life. However, with the iteration and update of drone technology, the manufacturing cost of drones has been reduced, and the adaptability to complex flight environments has been improved. The improper use of drones has also become a new management problem. For example, the use of drones for illegal photography in no-fly zones or dangerous transportation operations usually requires timely use of jamming technology to respond.

[0003] The working principle of a drone jammer is to interfere with the communication and control signals of a drone by emitting interference signals. Specifically, when encountering a drone that flies illegally, the drone jammer can obtain the frequency band where the drone's communication and control signals are located, and interfere with the communication interaction between the drone and the drone's controller by emitting interference signals in the corresponding frequency band, thereby forcing the drone to land or driving it away.

[0004] However, existing drone jammers are usually large in size and weight, which requires a large space for installation, complicated installation steps, high material costs, long production assembly and testing cycles, and low production efficiency.

[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0045] References to "one embodiment" or "example" or "example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed herein. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0046] In the related art, drone jammers usually include detection equipment and jamming equipment that are separated from each other, that is, the detection equipment is an independent entity, and the jamming equipment is an independent entity. For the multi-band receiving function of the detection equipment, each frequency band corresponds to a radio frequency channel, and each radio frequency channel mainly includes a detection antenna, an amplifier, a filter and other circuit structures. Multiple radio frequency channels receive radio frequency signals of different bands through the detection antenna, and input them to the radio frequency signal processing module for processing to realize the entire detection function;

[0047] The jamming device supports the same frequencies as the detection device, and also includes multiple jamming channels corresponding to multiple frequency bands. Each channel mainly includes a signal source, a power amplifier and a jamming antenna. The signal source is used to generate jamming signals, and the power amplifier is used to amplify the power of the jamming signals. Finally, the jamming signals are transmitted through the jamming antenna to achieve high-power suppression of drone targets.

[0048] However, as the RF frequency bands that drone jammers deal with increase, the number of channels of detection equipment and jamming equipment will also increase, resulting in an increase in the size, weight and structural complexity of the two, which in turn leads to an increase in the overall size and weight of drone jammers. The internal structure of drone jammers also becomes more complex. The space required for the installation of drone jammers is large, the installation steps are cumbersome, the material cost is high, the production assembly and testing cycles are long, and the production efficiency is low.

[0049] In order to solve the above technical problems, as one aspect of the present invention, a transceiver device for UAV interference is provided, such as Figures 1 to 4 As shown, the transceiver device includes a controller 100 (which may be a device management function module), a signal processing module 200, at least one transceiver circuit 300, and at least one antenna 400 corresponding to the transceiver circuit 300. The transceiver circuit 300 includes a signal generating module 310, a circulator 320, and a limiter 330, wherein:

[0050] The circulator 320 is used to transmit the signal generated by the signal generation module 310 to the corresponding antenna 400, and transmit the drone signal received by the antenna 400 to the limiter 330;

[0051] The limiter 330 is used to receive the signal transmitted by the circulator 320, and transmit the limited signal with an amplitude less than or equal to a preset amplitude threshold to the signal processing module 200;

[0052] The signal processing module 200 is used to generate drone identification information in response to the clipping signal;

[0053] The controller 100 is used to generate an interference transmission instruction according to the drone identification information, so that the signal generation module 310 generates an interference signal corresponding to the drone signal frequency in response to the interference transmission instruction.

[0054] In the transceiver device provided by the present invention, each transceiver circuit 300 includes a signal generating module 310, a circulator 320 and a limiter 330. The signal generating module 310 can transmit an interference signal unidirectionally to the antenna 400 through the circulator 320, and the antenna 400 can transmit the received drone signal unidirectionally to the limiter 330 through the circulator 320, thereby realizing signal transceiver (receiving drone signals and sending interference signals) using the same antenna and the same circuit structure.

[0055] That is, the present invention combines the radio frequency channel of the detection device and the interference channel of the interference device in the related art into the same transceiver circuit 300 of the transceiver device, and realizes signal reception and transmission through a single antenna 400; accordingly, when the transceiver device needs to realize the wide-band detection function through multiple channels, the transceiver device may include multiple transceiver circuits 300 and corresponding multiple antennas 400, thereby combining the multiple radio frequency channels of the detection device and the multiple interference channels of the interference device in the related art into multiple transceiver circuits 300, and combining the multiple detection antennas of the detection device and the multiple interference antennas of the interference device into multiple antennas 400.

[0056] The transceiver provided by the present invention simplifies the circuit structure for realizing the signal transceiver function, reduces the number of antennas, reduces the volume and weight of the transceiver, simplifies the internal structure of the transceiver, thereby reducing the manufacturing cost of the transceiver and improving the production efficiency of the transceiver. According to tests, under the premise of achieving the same function, the volume of the transceiver provided by the present invention can be reduced to 60% of the volume of the existing UAV jammer, and the production material cost of the transceiver provided by the present invention can be reduced to 70% of the material cost of the existing UAV jammer.

[0057] Furthermore, the transceiver provided by the present invention is smaller in size and requires less space for installation, thereby improving the adaptability of the transceiver to the installation environment and facilitating the expansion of the application scenarios of the transceiver (for example, it can be installed on the top of a building with a smaller installation area, or on a carrier).

[0058] It can be understood that the limiter 330 is mainly used to absorb the interference signal received by the circulator 320. Specifically, the drone signal received by the antenna 400 of the transceiver device usually has a relatively low power, while the interference signal generated by the signal generating module 310 has a relatively high power. Therefore, the present invention absorbs the higher power part through the limiter 330 and only transmits the drone signal to the signal processing module 200.

[0059] Specifically, the drone signal received by the antenna 400 is generally a low-power signal. When the low-power drone signal is input to the limiter 330 by the circulator 320, the limiter 330 is in an insertion loss state, and can transmit the drone signal to the subsequent circuit structure with lower loss;

[0060] When the standing wave of the antenna 400 is relatively poor, when the interference signal passes through the circulator 320, part of the power will be reflected back to the circulator 320 and input to the limiter 330 by the circulator 320. At this time, the limiter 330 will enter the limiting state, the insertion loss will increase and the leakage power will be absorbed to limit the signal amplitude output by the limiter 330 to not exceed a predetermined threshold, thereby protecting the subsequent circuit structure from overload damage and ensuring the safety of the circuit structure of the transceiver.

[0061] As an optional embodiment of the present invention, Figure 1 As shown, the output end of the signal generating module 310 is connected to the first end a of the circulator 320, the antenna 400 is connected to the second end b of the circulator 320 in a one-to-one correspondence, the input end of the limiter 330 is connected to the third end c of the circulator 320, the first end a and the second end b of the circulator 320 are unidirectionally connected, and the second end b and the third end c of the circulator 320 are unidirectionally connected.

[0062] It can be understood that the transceiver provided by the present invention is applicable to both full-duplex application scenarios and half-duplex application scenarios. That is, the action of the output end of the signal generation module 310 sending the interference signal to the antenna 400 through the circulator 320 and the action of the antenna 400 sending the received drone signal to the limiter 330 through the circulator 320 can occur simultaneously, realizing a full-duplex working mode;

[0063] Alternatively, the controller 100 may send an interference transmission instruction to the corresponding signal generation module 310 only when the antenna 400 does not receive the drone signal, so that the time period when the antenna 400 sends the interference signal is staggered with the time period when the antenna 400 receives the drone signal, thereby realizing a half-duplex working mode.

[0064] As an optional embodiment of the present invention, Figure 1 As shown, the transceiver device may include only one transceiver circuit 300 and one antenna 400 .

[0065] Alternatively, in order to realize the wideband detection function, as a preferred embodiment of the present invention, as Figures 2 to 4 As shown, the transceiver device includes multiple (i.e., two or more, more than two are shown in the figure) transceiver circuits 300 (first transceiver circuit 300-1, second transceiver circuit 300-2, ... nth transceiver circuit 300-n) and corresponding multiple antennas 400 (first antenna 400-1, second antenna 400-2, ... nth antenna 400-n).

[0066] It is understandable that when the multiple antennas 400 are used to receive and transmit signals in different frequency bands respectively, the multiple antennas 400 can be designed to have different shapes, structures and materials.

[0067] As a preferred embodiment of the present invention, Figures 1 to 4 As shown, the transceiver device also includes an amplifier 340, which is connected between the output end of the limiter 330 and the input end of the signal processing module 200. The amplifier 340 is used to increase the amplitude of the limited signal output by the limiter 330 to ensure the accuracy of the signal processing module 200 in identifying the drone signal.

[0068] As an optional implementation of the present invention, the amplifier 340 is a low noise amplifier 340 .

[0069] As a preferred embodiment of the present invention, Figures 1 to 4 As shown, the transceiver device also includes a filter 350, which is connected between the output end of the amplifier 340 and the input end of the signal processing module 200. The filter 350 is used to filter out the part of the signal output by the amplifier 340 whose frequency exceeds the preset frequency range, and send the rest to the signal processing module 200, thereby reducing the interference information in the signal received by the signal processing module 200.

[0070] It is understandable that when the multiple antennas 400 are respectively used to receive and transmit signals in different frequency bands, the multiple filters 350 may also correspond to different preset frequency ranges.

[0071] As an optional embodiment of the present invention, Figures 1 to 4 As shown, the signal generating module 310 includes a signal source 311 and a power amplifier 312;

[0072] The signal source 311 is used to generate a precursor signal corresponding to the UAV signal frequency in response to the jamming transmission instruction;

[0073] The power amplifier 312 is used to amplify the amplitude of the precursor signal to obtain an interference signal.

[0074] To facilitate understanding by technicians, the following provides a specific process in which the transceiver device receives a drone signal and sends a drone interference signal to the drone when the transceiver device includes multiple transceiver circuits 300 and multiple antennas 400:

[0075] like Figure 2 , Figure 3 As shown, the transceiver device includes a controller 100, a signal processing module 200, a plurality of transceiver circuits 300 (a first transceiver circuit 300-1, a second transceiver circuit 300-2, ... an nth transceiver circuit 300-n) and a corresponding plurality of antennas 400 (a first antenna 400-1, a second antenna 400-2, ... an nth antenna 400-n), wherein:

[0076] The first transceiver circuit 300-1 includes a first signal generating module 310-1, a first circulator 320-1, a first limiter 330-1, a first amplifier 340-1 and a first filter 350-1, the first signal generating module 310-1 is connected between the controller 100 and the first circulator 320-1, the first signal generating module 310-1 includes a first signal source 311-1 and a first power amplifier 312-1, the first limiter 330-1, the first amplifier 340-1 and the first filter 350-1 are sequentially connected between the first circulator 320-1 and the signal processing module 200;

[0077] The second transceiver circuit 300-2 includes a second signal generating module 310-2, a second circulator 320-2, a second limiter 330-2, a second amplifier 340-2 and a second filter 350-2. The second signal generating module 310-2 is connected between the controller 100 and the second circulator 320-2. The second signal generating module 310-2 includes a second signal source 311-2 and a second power amplifier 312-2. The second limiter 330-2, the second amplifier 340-2 and the second filter 350-2 are sequentially connected between the second circulator 320-2 and the signal processing module 200. …The nth transceiver circuit 300-n includes an nth signal generating module 310-n, an nth circulator 320-n, an nth limiter 330-n, an nth amplifier 340-n and an nth filter 350-n. The nth signal generating module 310-n is connected between the controller 100 and the nth circulator 320-n. The nth signal generating module 310-n includes an nth signal source 311-n and an nth power amplifier 312-n. The nth limiter 330-n, the nth amplifier 340-n and the nth filter 350-n are connected in sequence between the nth circulator 320-n and the signal processing module 200.

[0080] Taking the first transceiver circuit 300-1 and the first antenna 400-1 corresponding to the first frequency band as an example, when the first antenna 400-1 receives a drone signal with a frequency within the first frequency band, the drone signal enters the first circulator 320-1, the first limiter 330-1, the first amplifier 340-1, the first filter 350-1 and the signal processing module 200 in sequence. The signal processing module 200 analyzes the radio signal, and after parsing out the target object, sends the drone identification information with relevant information of the target object to the controller 100. The controller 100 sends an interference transmission instruction to the first signal generating module 310-1 of the first transceiver circuit 300-1. The first signal source 311-1 generates a precursor signal corresponding to the drone signal frequency. The first power amplifier 312-1 amplifies the precursor signal to form an interference signal, and outputs it to the first antenna 400-1 through the first circulator 320-1. Finally, the first antenna 400-1 radiates the interference signal to interfere with the target object and achieve the purpose of expulsion.

[0081] As an optional embodiment of the present invention, Figure 4 As shown, the transceiver device includes five transceiver circuits 300 and corresponding five antennas 400 (a first antenna 400-1, a second antenna 400-2, ..., a fifth antenna 400-5).

[0082] Specifically, Figure 4As shown, the first transceiver circuit 300-1 includes a first signal generating module 310-1, a first circulator 320-1, a first limiter 330-1, a first amplifier 340-1 and a first filter 350-1, the first signal generating module 310-1 is connected between the controller 100 and the first circulator 320-1, the first signal generating module 310-1 includes a first signal source 311-1 and a first power amplifier 312-1, the first limiter 330-1, the first amplifier 340-1 and the first filter 350-1 are sequentially connected between the first circulator 320-1 and the signal processing module 200;

[0083] The second transceiver circuit 300-2 includes a second signal generating module 310-2, a second circulator 320-2, a second limiter 330-2, a second amplifier 340-2 and a second filter 350-2. The second signal generating module 310-2 is connected between the controller 100 and the second circulator 320-2. The second signal generating module 310-2 includes a second signal source 311-2 and a second power amplifier 312-2. The second limiter 330-2, the second amplifier 340-2 and the second filter 350-2 are sequentially connected between the second circulator 320-2 and the signal processing module 200. ...the fifth transceiver circuit includes a fifth signal generating module 310-5, a fifth circulator 320-5, a fifth limiter 330-5, a fifth amplifier 340-5 and a fifth filter 350-5, the fifth signal generating module 310-5 is connected between the controller 100 and the fifth circulator 320-5, the fifth signal generating module 310-5 includes a fifth signal source 311-5 and a fifth power amplifier 312-5, the fifth limiter 330-5, the fifth amplifier 340-5 and the fifth filter 350-5 are sequentially connected between the fifth circulator 320-5 and the signal processing module 200.

[0086] As an optional embodiment of the present invention, the transceiver device further includes a shell, the controller 100, the signal processing module 200 and the transceiver circuit 300 are all arranged inside the shell, and the antenna 400 is fixedly arranged on the surface of the shell.

[0087] As an optional embodiment of the present invention, the shell of the transceiver device has at least one mounting portion, the mounting portion has a mounting through hole, and the mounting portion is used to be fixedly connected to a building or a vehicle by a fastener passing through the mounting through hole.

[0088] As a second aspect of the present invention, a method for controlling interference of a drone is provided. The control method is implemented by the controller 100 of the transceiver provided by the present invention. The control method includes:

[0089] Step S1, in response to the drone identification information generated by the signal processing module 200, generating an interference transmission instruction corresponding to the drone signal frequency;

[0090] Step S2: sending an interference transmission instruction to the signal generation module 310 of at least one transceiver circuit 300, so that the corresponding antenna 400 outputs an interference signal corresponding to the drone signal frequency.

[0091] In the UAV interference control method provided by the present invention, the antenna for receiving the UAV signal and the antenna for sending the interference signal can be the same antenna 400. The present invention combines the radio frequency channel of the detection device and the interference channel of the interference device in the related technology into the same transceiver circuit 300 of the transceiver device, and realizes signal reception and transmission through a single antenna 400, which simplifies the circuit structure for realizing the signal reception and transmission function, reduces the number of antennas, reduces the volume and weight of the transceiver device, and simplifies the internal structure of the transceiver device, thereby reducing the manufacturing cost of the transceiver device and improving the production efficiency of the transceiver device.

[0096] That is, in an embodiment of the present invention, multiple antennas 400 are used to receive drone signals of different frequency bands and output interference signals of different frequency bands, thereby expanding the overall frequency band width that can be detected by the transceiver device and improving the adaptability of the transceiver device to different types of drones.

[0097] As an optional implementation of the present invention, step S2 may also include:
