DETAILED DESCRIPTION
[0037] The core of this utility model is to provide an integrated reconnaissance and interference device. By setting a radio frequency switch between the detection antenna and the detection module, the switching between the detection function and the interference function can be achieved more quickly without repeatedly restarting the detection module, thereby improving the reliability of the device's working performance.
[0038] To help those skilled in the art better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the embodiments described are only a portion of the present invention, not all of the embodiments. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0039] like Figure 1 As shown, Figure 1 A schematic diagram of the circuit structure of an integrated interference detection device provided in an embodiment of the present application.
[0040] In a specific embodiment of the present application, the integrated interference detection device may include:
[0041] Main control module 1; power amplifier module 2 and detection module 3 connected to the main control module 1; interference antenna 4 connected to the power amplifier module 2; detection antenna 5; RF switch 6;
[0042] The RF switch 6 is a single-pole double-throw switch, the active end of the RF switch 6 is connected to the detection antenna 5; the first fixed end of the RF switch 6 is connected to the detection module 3; the second fixed end of the RF switch 6 is connected to the load 7;
[0043] The main control module 1 is connected to the control end of the radio frequency switch 6 and is used to control the active end of the radio frequency switch 6 to switch between being connected to the first fixed end and being connected to the second fixed end.
[0044] like Figure 1As shown, the main control module 1 in this embodiment can specifically adopt a PLC control chip or a single-chip microcomputer; and the power amplifier module 2 can be connected to the enable pin of the main control module 1. When the main control module 1 outputs an enable signal to the power amplifier module 2, the power amplifier module 2 can start to output the interference signal through the interference antenna 4.
[0045] In practical applications, multiple power amplifier modules 2 may be included. For example, in this embodiment, eight power amplifier modules 2 may be provided, each configured to output interference signals in eight different frequency bands, namely, 0.4 GHz, 0.8 GHz, 0.9 GHz, 1.2 GHz, 1.5 GHz, 2.4 GHz, 5.2 GHz, and 5.8 GHz. Furthermore, the eight power amplifier modules 2 should be connected to eight different enable pins of the main control module 1, so that the main control module 1 can independently control the start and stop of each power amplifier module 2.
[0046] In addition, it is further considered that if each power amplifier module 2 works alone for a long time, the temperature of the power amplifier module 2 may be too high, thereby affecting the working performance of the power amplifier module 2; for this reason, in an optional implementation method of this embodiment, the main control module 1 can also be connected to a timer to time the working time of each power amplifier module 2. Once the working time of a single power amplifier module 2 reaches the set time, the main control module 1 can control the power amplifier module 2 to stop working for a short period of time and then restart working, thereby ensuring the working performance and service life of the power amplifier module 2.
[0047] Based on the above discussion, the main control module 1 is further connected to a detection module 3, and the detection module 3 is connected to a detection antenna 5. Therefore, when monitoring whether there are unauthorized drones flying in the airspace, the detection antenna 5 can receive the radio frequency signal of the communication between the drone and its corresponding ground equipment. Once the radio frequency signal is detected, the detection module 3 can analyze and process the radio frequency signal to determine what frequency band of interference signal the power amplifier module 2 needs to use to interfere with the drone.
[0048] If the detection function is turned on at the same time as the jamming function in the integrated reconnaissance and jamming device, the detection antenna 5 will obviously receive the jamming signal output by the jamming antenna 4. In general, in order to jam the drone, the jamming signal is often much stronger than the drone's normal communication signal, thereby covering the drone's communication signal. When this jamming signal is transmitted to the detection module 3 through the detection antenna 5, it may cause damage to the detection module 3. For this reason, in actual applications, the jamming function and the detection function in the integrated reconnaissance and jamming device cannot be turned on at the same time.
[0049] On this basis, in the integrated reconnaissance and interference device, the detection function and the interference function often need to be operated alternately. For example, the detection function is turned on first. Once a drone is detected invading a specific airspace, the detection function is turned off and the interference function is turned on. After the interference function has been activated for a period of time, the detection function is activated again to monitor whether the drone has been driven out of the specific airspace. If not, the detection function is turned off again and the interference function is activated. This process is repeated to ensure that there are no invading drones in the monitored airspace.
[0050] It is understandable that in the above-mentioned working process of the integrated reconnaissance and interference device, both the detection function and the interference function need to be repeatedly turned on and off. For the interference function, different control signals can be outputted only through the enable pin of the main control module 1; and for the detection module 3, it is necessary to cut off the power to it to turn it off, which affects the service life of the detection module 3; and each time the detection module 3 is powered on and restarted, there is a self-test process, and the frequent power on and off consumes a long time, which leads to inflexible switching between the detection function and the interference function.
[0051] To this end, in this embodiment, a radio frequency switch 6 is further provided between the detection antenna 5 and the detection module 3. This radio frequency switch 6 can be a single-pole double-throw switch. Furthermore, the active end of the radio frequency switch 6 is connected to the detection antenna 5, the first fixed end is connected to the detection module 3, and the second fixed end is connected to the load 7. Thus, as the active end of the radio frequency switch 6 switches between connecting to the first fixed end and the second fixed end, the detection antenna 5 can switch between connecting to the detection module 3 and connecting to the load 7.
[0052] When the detection antenna 5 is connected to the detection module 3, the RF signal received by the detection antenna 5 can be transmitted to the detection module 3 via the RF switch 6, thus activating the detection function. When the detection antenna 5 is connected to the load 7, the detection antenna 5 and the detection module 3 are disconnected from each other, and the detection function is also disabled. At this time, even if the detection antenna 5 receives an RF signal, the RF signal is transmitted to the load 7 and eliminated by the load 7, preventing the RF signal from leaking and preventing other signals from interfering with the line. For the load 7 in this embodiment, an SMA (SubMiniature version A) coaxial load terminal can be used.
[0053] Based on the above discussion, in an optional embodiment of the present application, the detection module 3 includes:
[0054] The RF spectrum detection module 31 is used to determine the frequency band of the signal collected by the detection antenna 5;
[0055] The CRPC protocol decoding module 32 is used to determine the position information of the detection target based on the signal collected by the detection antenna 5;
[0056] The detection antenna 5 includes a first detection antenna 51 and a second detection antenna 52;
[0057] The RF switch 6 includes a first RF switch 61 and a second RF switch 62;
[0058] The movable end of the first RF switch 61 is connected to the first detection antenna 51 , and the first fixed end of the first RF switch 61 is connected to the RF spectrum detection module 31 ;
[0059] The movable end of the second RF switch 62 is connected to the second detection antenna 52 , and the first fixed end of the second RF switch 62 is connected to the CRPC protocol decoding module 32 .
[0060] The detection module 3 in this embodiment includes two modules: an RF spectrum detection module 31 and a CRPC protocol decoding module 32. Among them, the RF spectrum detection module 31 is specifically a radio frequency module, which can analyze and determine the frequency band of the signal collected by the detection antenna 5; and the CRPC (Cognitive Radio Protocol Cracking) protocol decoding module 32 can locate the current flight longitude and latitude of the drone, the longitude and latitude of the drone's return point, and the longitude and latitude of the remote control for remotely controlling the drone based on the signal detected by the detection antenna 5, thereby obtaining more comprehensive drone information.
[0061] In order to ensure that the RF spectrum detection module 31 and the CRPC protocol decoding module 32 can each receive a sufficiently strong signal, a corresponding first detection antenna 51 and a second detection antenna 52 can be configured for the two different modules respectively; accordingly, a first RF switch 61 is provided between the first detection antenna 51 and the RF spectrum detection module 31, which can control whether the first detection antenna 51 and the RF spectrum detection module 31 are conductive or not; and a second RF switch 62 is provided between the second detection antenna 52 and the CRPC protocol decoding module 32, which can control whether the second detection antenna 52 and the CRPC protocol decoding module 32 are conductive or not. In addition, the control end of the first RF switch 61 and the control end of the second RF switch 62 can be connected to the two control pins of the main control module 1 respectively, so that the main control module 1 can independently control the switching on and off states of the first RF switch 61 and the second control switch; therefore, in actual applications, if only the signal frequency band of the drone needs to be detected, the main control module 1 can only control the active end of the first RF switch 61 to connect to its first fixed end, that is, to connect the connection between the first detection antenna 51 and the RF spectrum detection module 31, and control the active end of the second RF switch 62 to connect to the second fixed end, that is, to disconnect the first detection antenna 51 and the RF spectrum detection module 31. Open the connection between the second detection antenna 52 and the CRPC protocol decoding module 32; of course, the main control module 1 can also simultaneously control the first RF switch 61 and the second RF switch 62 to be in a state where the active end is connected to the first fixed end; or, the main control module 1 controls the active end of the first RF switch 61 to be connected to its second fixed end while controlling the active end of the second RF switch 62 to be connected to its first fixed end; or, the main control module 1 simultaneously controls the first RF switch 61 and the second RF switch 62 to be in a state where the active end is connected to the second fixed end; specific control and adjustment can be performed based on actual monitoring needs.
[0062] Based on the above embodiment, refer to Figure 2 In another optional embodiment of the present application, based on the fact that the detection module 3 includes the RF spectrum detection module 31 and the CRPC protocol decoding module 32, the integrated detection and detection device may further include:
[0063] There are multiple first detection antennas 51 and multiple second detection antennas 52;
[0064] The first RF switch 61 and the first detection antenna 51 are connected via a first combiner 81 ; wherein the output port of the first combiner 81 is connected to the active end of the first RF switch 61 ; and each input port of the first combiner 81 is connected to one of the first detection antennas 51 ;
[0065] The second RF switch 62 and the second detection antenna 52 are connected via a second combiner 82 ; wherein the output port of the second combiner 82 is connected to the first fixed end of the second RF switch 62 ; and each input port of the second combiner 82 is connected to a second detection antenna 52 .
[0066] It is understandable that the main function of a combiner is to combine two or more RF signals into one signal and output it together. A combiner generally has two or more input ports and only one output port.
[0067] In this embodiment, the number of input ports of the first combiner 81 is the same as the number of first detection antennas 51, so each input port of the first combiner 81 is connected to a first detection antenna 51. Therefore, when each first detection antenna 51 receives a radio frequency signal, it can be combined into one radio frequency signal through the first combiner 81 and transmitted to the RF spectrum detection module 31 through the first radio frequency switch 61. Compared with a single first detection antenna 51, the radio frequency signals synchronously detected by multiple first detection antennas 51 are combined to increase the strength of the radio frequency signal, which can also, to a certain extent, expand the airspace range that the integrated reconnaissance and jamming device can monitor.
[0068] Similarly, each input port of the second combiner 82 is also connected to a second detection antenna 52, so that the RF signals received by multiple second detection antennas 52 can be combined through the second combiner 82 and transmitted to the CRPC protocol decoding module 32 through the second RF switch 62. This can also enhance the signal strength received by the CRPC protocol decoding module 32, thereby expanding the airspace range that the integrated reconnaissance and jamming device can monitor.
[0069] Based on the above embodiment, even if a plurality of the first detection antenna 51 and the second detection antenna 52 are provided, the implementation is not limited to the above one.
[0070] Reference Figure 3 In another optional embodiment of the present application, based on the fact that the detection module 3 includes the RF spectrum detection module 31 and the CRPC protocol decoding module 32, the integrated detection and detection device may further include:
[0071] There are multiple first detection antennas 51 and multiple second detection antennas 52;
[0072] Accordingly, there are multiple first RF switches 61 and multiple second RF switches 62; the main control module 1 is individually connected to the control end of each first RF switch 61 and the control end of each second RF switch 62, and is used to independently control the switching of the active end of each first RF switch 61 and each second RF switch 62 between connecting to the first fixed end and connecting to the second fixed end;
[0073] Each first detection antenna 51 is connected to the RF spectrum detection module 31 via a first RF switch 61; each second detection antenna 52 is connected to the CRPC protocol decoding module 32 via a second RF switch 62;
[0074] Furthermore, the first fixed end of each first RF switch 61 and the RF spectrum detection module 31 are connected via a first combiner 81; the first fixed end of each first RF switch 61 is connected to an input port of the first combiner 81, and the output port of the first combiner 81 is connected to the RF spectrum detection module 31;
[0075] The first fixed end of each second RF switch 62 and the CRPC protocol decoding module 32 are connected through the second combiner 82; the first fixed end of each second RF switch 62 is connected to an input port of the second combiner 82, and the output port of the first combiner 81 is connected to the CRPC protocol decoding module 32.
[0076] In this embodiment, multiple first detection antennas 51 and second detection antennas 52 are also provided. However, the difference is that in this embodiment, each first detection antenna 51 is configured with a first RF switch 61, and each first detection antenna 51 is respectively connected to the active end of the corresponding first RF switch 61. On this basis, the first fixed end of each first RF switch 61 is connected to an input port of the first combiner 81, and the second fixed end is connected to the load 7. In addition, the output port of the first combiner 81 is connected to the RF spectrum detection module 31. Therefore, the RF signals received by each first detection antenna 51 can also be transmitted to the first combiner 81 through the corresponding first RF switch 61, and then combined into one RF signal by the first combiner 81 and transmitted to the RF spectrum detection module 31.
[0077] In addition, in this embodiment, whether the active end of each first RF switch 61 is connected to the first fixed end or the second fixed end is independently controlled by the main control module 1; thus, in actual application, the number of first RF switches 61 connected to the active end and the first fixed end can be controlled according to the needs of the airspace actually monitored. For example, when it is necessary to monitor a larger airspace range, the active ends and the first fixed ends of more first RF switches 61 can be controlled to be connected; and when the airspace range to be monitored is relatively small, the active ends and the first fixed ends of fewer first RF switches 61 can be controlled to be connected. For example, when it is rainy and the interference to the RF signal during transmission is relatively large, the active end and the first fixed end of the first RF switch 61 can also be controlled.
[0078] Of course, the first detection antennas 51 may also be redundant with each other. When one or more detection antennas 5 fail, the first RF switches 61 may be controlled to connect the first detection antennas 51 that are not at fault to the RF spectrum detection module 31 .
[0079] Similarly, each second detection antenna 52 is also connected to the active end of the corresponding second RF antenna; the first fixed end of each second RF antenna is respectively connected to the input port of the second combiner 82, and the second fixed end is commonly connected to the load 7; and the output port of the second combiner 82 is connected to the CRPC protocol decoding module 32; on this basis, the main control module 1 can also independently control the switching of the active end of each second RF switch 62 between connecting to the first fixed end and connecting to the second fixed end, that is, it can independently control whether each second detection antenna 52 is connected to the CRPC protocol decoding module 32; thus, in actual application, the number of connected CRPC protocol decoding modules 32 can also be controlled based on actual needs.
[0080] Optionally, in practical applications, the number of the first detection antennas 51 may be greater than the number of the second detection antennas 52 , so as to ensure the detection of the signal frequency band of the drone as much as possible.
[0081] Based on any of the above embodiments, in an optional embodiment of the present application, the main control module 1, the power amplifier module 2, the detection module 3 and the RF switch 6 are all connected to the power module 9 through a one-to-many junction box 91, thereby enabling a single power module 9 to synchronously power multiple different module devices.
[0082] In addition, Figures 1 to 3 In order to avoid the circuit being too complicated, the circuits connecting each power amplifier module 2 and the one-to-many junction box 9 are not directly shown, but it can be understood that each power amplifier module 2 is connected to the power module 9 through the one-to-many junction box 91; similarly, in Figure 3 There is no direct output of the circuit connecting the output end of the step-down module and the power supply end of each RF switch 6, but the power supply end of each RF switch 6 can be connected to the power module 9 through the step-down module 92.
[0083] On this basis, the operating voltage of the RF switch 6 is relatively low. In practical applications, a step-down module 92 is further provided between the RF switch 6 and the one-to-many junction box 91 ; specifically, the step-down module 92 may be a DC-DC module.
[0084] In summary, in the detection and interference integrated device of the present application, a radio frequency switch is provided between the detection module and the detection antenna, so that the detection antenna can switch between connecting to the detection module and connecting to the load. Therefore, when the main control module controls the power amplifier module to work, the active end and the second fixed end of the radio frequency switch can be controlled to be connected, so that the radio frequency signal received by the detection antenna is introduced into the load and eliminated. There is no need to shut down the detection module, and the interference signal output by the power amplifier module through the interference antenna can be avoided from being transmitted to the detection module through the detection antenna. The load eliminates unnecessary radio frequency signals, and can also avoid the radio frequency signal from causing unnecessary interference to other devices. On this basis, when the main control module controls the power amplifier module to stop working, The detection function is operated and needs to be started, so when the detection module and the detection antenna are disconnected, the detection module is not shut down, and there is no need to restart. The main control module only needs to connect the active end of the RF switch to the first fixed end to make the detection antenna and the detection module conductive, thereby starting the detection function; it can be seen that the start and stop of the detection function in the present application can be achieved only by controlling the connection state of the RF switch by the main control module, and there is no need to restart and shut down the detection module, which saves the time spent on repeated restarts of the detection module to a great extent, and avoids damage to the detection module caused by repeated restarts, thereby improving the speed of switching between the detection function and the interference function in the detection and interference integrated device, and also improving the reliability of the working performance of the device.
