[0024] Fig. 1 is a logical structure diagram of a software radio module according to an embodiment of the application. The software radio module 1 of the embodiment includes a functional module 11 and an interface component 12. The functional module 11 is electrically connected to the interface component 12, and the interface component 12 is further configured to be detachably electrically connected to an interface component of a control terminal (not shown) and / or another software radio module (not shown). The interface component 12 is configured to receive control information from the control terminal. The functional module 11 is configured to generate a radio frequency signal of a corresponding frequency band based on the control information.

[0025] In this embodiment, the interface component 12 of the software radio module 1 can be electrically connected with the control terminal and the interface component of other software radio module, but the actual electrical connection relationship of the interface component 12 can be different according to the application scenario. That is, the interface component 12 is also used for detachable electrical connection with the interface component of the control terminal and / or other software radio module, which means that the external electrical connection mode of the interface component 12 of the software radio module 1 can be different in different application scenarios, for example, the software radio module 1 can be detachably electrically connected with the control terminal through the interface component 12, or the software radio module 1 can be detachably electrically connected with the interface component of other software radio module, or the software radio module 1 can be detachably electrically connected with the interface component of other software radio module and the control terminal through the interface component 12. Therefore, based on the above setting mode of the interface component 12, the software radio module 1 can be flexibly configured to be suitable for different application scenarios.

[0026] The control end is, for example, a single-chip microcomputer, a CPU, etc. The function module 11 is, for example, capable of generating a radio frequency signal of a corresponding frequency band based on the control information. The control information is, for example, an on-off control signal to control the function module 11 to start or stop running. The function module 11 is, for example, implemented in a software radio architecture, so that the relevant functions can be realized according to the actual application scenario. After receiving the on control signal, the function module 11 can generate a radio frequency signal of a corresponding frequency band capable of realizing a specific function. After input to the antenna, the radio frequency signal can be directly transmitted. If applied to the field of anti-unmanned aerial vehicle (UAV) systems, after receiving the on control signal, the function module 11 can generate an UAV interference code (for example, the format of the interference code, such as the bandwidth, frequency band, and data length, is the same as that of the UAV communication signal, but the content is noise), and process the UAV interference code through modulation, amplification, etc. to obtain an UAV interference signal, and transmit the UAV interference signal through the antenna. If applied to the field of frequency interference, after receiving the on control signal, the function module 11 can generate a frequency interference code (for example, the format of the interference code generated for 5G communication signals is the same as that of the 5G communication signal, and the content is noise), and process the frequency interference code through modulation, amplification, etc. to form a frequency interference signal and transmit the frequency interference signal through the antenna to interfere with illegal wireless communication equipment. It should be noted that the specific way in which the function module 11 generates the radio frequency signal can be that the function module 11 directly generates a corresponding source signal in real time based on an algorithm configured in advance after receiving the control information, and then processes the source signal through modulation, power amplification, etc. to output the radio frequency signal. Alternatively, the function module 11 can read a corresponding source signal (for example, an UAV interference code for a certain type of UAV) from a storage device after receiving the control information, and then process the source signal through modulation, power amplification, etc. to output the radio frequency signal.

[0027] In addition, the above-mentioned control information is not limited to the on-off control signal, and can also be a source signal (for example, an UAV interference code). After the function module 11 receives the source signal, the function module 11 processes the source signal through modulation, power amplification, etc. to output the radio frequency signal. These are within the protection scope of the present application.

[0028] In addition, the frequency band of the radio frequency signal can also be configured according to actual needs. Taking the application of the anti-UAV system as an example, the control end can configure the frequency band of the UAV interference signal generated by the software radio module 1 according to actual needs, so as to adapt to the characteristics of continuous updating and iteration of UAV models. Therefore, the technical solution of the embodiment improves the flexibility of system configuration.

[0029] In practical applications, multiple software radio modules 1 provided by the embodiment can be used to form a system. Since each interface component 12 of each software radio module 1 has the above-mentioned characteristics, multiple software radio modules 1 can be cascaded to form a wireless communication system, such as a frequency interference system (in which case, each software radio module 1 can implement the function of frequency interference), a UAV countermeasure system (in which case, each software radio module 1 can implement the function of UAV countermeasures), and the like. In the wireless communication system, all software radio modules 1 can simultaneously transmit multiple radio frequency signals. For example, in a UAV countermeasure system, different software radio modules 1 can simultaneously transmit interference signals (interference signals are one of radio frequency signals) of different frequency bands to interfere with the communication of different UAVs, thereby improving the countermeasure effect and efficiency. In addition, the number of software radio modules 1 can be increased or decreased according to actual needs without major changes to the wireless communication system. For example, if the types of UAVs to be countered increase, the number of software radio modules 1 can be increased to counter the newly added UAVs.

[0030] Therefore, by optimizing the connection mode of the interface component 12 and the interaction mode between the functional module 11 and the control end, the embodiment can equip different numbers of software radio modules 1 according to actual scenarios, and by configuring each software radio module 1, different frequency band interference signals can be simultaneously transmitted, thereby being applicable to various application scenarios and improving the flexibility of system configuration, and being more suitable for changing UAV countermeasure scenarios.

[0031] Further, as shown in FIG. 1, the interface component 12 is also configured to send state information of the software radio module 1 to the control end. The state information includes, for example, identity information, power-on completion information, configuration completion information, upgrade completion information, and the like. The technical solution of the embodiment not only enables the control end to control the functional module 11 in the software radio module 1, but also enables the control end to know the state of the software radio module 1 in time, so as to facilitate the control end to control the entire system uniformly and orderly, thereby ensuring the operation reliability.

[0032] Figure 2 is a logic structure diagram of a software radio module in an embodiment of the present application. The software radio module 1 in this embodiment includes a function module 11 and an interface component 12 electrically connected, wherein the interface component 12 includes a first interface 121. The first interface 121 is used to receive control information from a control terminal and send the control information to the function module 11. The first interface 121 is, for example, an I / O control interface (such as a connector of GH series), an Ethernet interface, or other types of interfaces (such as other interfaces similar to the connector of GH series and the Ethernet interface) that can output high and low levels. One end of the first interface 121 is used to be detachably electrically connected with one of the first connection terminals of the control terminal (not shown), and the other end of the first interface 121 is electrically connected with the function module 11.

[0033] In this embodiment, the control terminal can be provided with a plurality of first connection terminals. Since the first interface 121 can be detachably electrically connected with one of the first connection terminals of the control terminal, the control terminal can be connected with a plurality of software radio modules 1 one by one through the plurality of first connection terminals. This connection mode is a star cascade mode. In this embodiment, the control terminal can send control information to each software radio module 1 through the first interface 121 to control all the software radio modules 1. This star cascade mode has the advantages of low cost, simple operation mode, and fast response, and is suitable for application scenarios that pay more attention to response speed.

[0034] Figure 3 is a logic structure diagram of a software radio module in an embodiment of the present application. The software radio module 1 in this embodiment is a specific scheme in the embodiment shown in Figure 2. In this embodiment, the main function of the software radio module 1 includes amplifying and outputting a radio frequency signal. The control information includes an enable signal. The function module 11 includes a power amplification unit 112, which is electrically connected with the first interface 121, and the power amplification unit 112 is used to output a radio frequency signal when the enable signal is received.

[0035] In this embodiment, the control end can control the software radio module 1 to turn on or off. The specific control mode is, for example, that an enable signal can be sent to the software radio module 1 that needs to work according to actual needs, and no enable signal needs to be sent to the software radio module 1 that does not need to work, at this time, the enable signal can be any type of signal. Alternatively, an enable signal can also be sent to the software radio module 1 that needs to work, and a shutdown signal is sent to the software radio module 1 that does not need to work (for example, the same pin is used for the enable signal and the shutdown signal, when the pin transmits a high level, it is considered to transmit an enable signal, and when the pin is low, it is considered to transmit a shutdown signal). In this embodiment, since the functional module 11 includes the power amplification unit 112, when the enable signal is received through the first interface 121, the software radio module 1 is equivalent to a power amplifier, which can access any kind of input signal (for example, a radio frequency signal corresponding to a frequency interference code with relatively low power, a radio frequency signal corresponding to a drone interference code with relatively low power), and the input signal is power amplified to obtain a radio frequency signal, and then transmitted through an antenna, so as to be applicable to various application scenarios that need a power amplifier.

[0036] Therefore, in this embodiment, the control end controls each software radio module 1 through an enable signal, which is convenient to operate, fast to respond, and can save unnecessary power consumption to prolong the service life of the software radio module 1. In addition, since the software radio module 1 in this embodiment is equivalent to a power amplifier, it can be applied to various application scenarios.

[0037] Further, the functional module 11 further comprises other devices. As shown in FIG. 3, in this embodiment, the functional module 11 further comprises a signal processing unit 111, which is electrically connected with the power amplification unit 112 and the first interface 121 respectively. The signal processing unit 111 and / or the power amplification unit 112 are / is configured to send state information to the control end through the first interface 121. The state information can be a signal generated according to the running state of the software radio module 1, for example, a power-on completion information of the software radio module 1 (including the power amplification unit 112 and the signal processing unit 111). The signal processing unit 111 may, for example, first generate a drone jamming code for jamming a drone of a certain frequency band, and then generate a corresponding initial signal after modulation and other processing, and then obtain a drone jamming signal of the corresponding frequency band after amplification by the power amplification unit 112. Moreover, different software radio modules 1 can generate drone jamming signals of different frequency bands. Therefore, by adopting multiple software radio modules 1, different types of drones can be simultaneously jammed. In this embodiment, when the power supply is connected to the functional module 11, and after the power amplification unit 112 and the signal processing unit 111 are both powered on, the signal processing unit 111 and / or the power amplification unit 112 can send a power-on completion information (a signal for indicating power-on completion) to the first interface 121, and the first interface 121 can then transmit the power-on completion information to the control end. Since the power-on completion time of the signal processing unit 111 is generally later than that of the power amplification unit 112, the signal processing unit 111 can be configured to send the power-on completion information after being powered on. Alternatively, only the power amplification unit 112 can be configured to send the power-on completion information. Of course, the power-on completion information can also be sent by the signal processing unit 111 and the power amplification unit 112 respectively (i.e., the power amplification unit 112 sends a power-on completion information indicating that it has completed power-on after being powered on, and the signal processing unit 111 also sends a power-on completion information indicating that it has completed power-on after being powered on), as long as the information that both of them have completed power-on can be conveyed. In this embodiment, the power-on completion information can be a high-level signal. In this embodiment, the software radio module 1 can make the control end know the real-time state of the software radio module 1 in time by sending state information to the control end. Finally, it should be noted that according to actual application requirements, the state information sent by the software radio module 1 to the control end can also be other types of state information, for example, information representing whether the running is normal, which is not limited here.

[0038] Further, in an optional embodiment, the power amplifying unit 112 is also configured to send operation indication information, for example, enable success information, to the control end through the first interface 121, which represents that the power amplifying unit 112 has completed normal starting. In this embodiment, after the power amplifying unit 112 is powered on, the control end can send an enable signal to the power amplifying unit 112 through the first interface 121. After receiving the enable signal, the power amplifying unit 112 can start normally, and after starting, the power amplifying unit 112 sends the enable success information to the control end through the first interface 121, so that the control end can know the operation result of the power amplifying unit 112 in time. In this embodiment, the signal processing unit 111 can monitor the pin of the first interface 121 for receiving the enable signal, so as to identify whether the control end sends the enable signal, and thus the control end does not need to send an enable signal to the signal processing unit 111 additionally. For example, assuming that the enable signal is high level, when the signal processing unit 111 monitors that the pin of the first interface 121 for receiving the enable signal is high level, it is determined that the control end sends the enable signal, and then the signal processing unit 111 can complete the enable by itself. It can be understood that in other embodiments, in order to enable the signal processing unit 111, the power amplifying unit 112 can also send the enable signal to the signal processing unit 111, or the control end can additionally send the enable signal to the signal processing unit 111 through the first interface 121. Finally, it should be noted that the operation indication information sent to the control end can also be other operation indication information except the enable success information, or operation indication information of other devices except the power amplifying unit.

[0039] Based on the software radio module 1 shown in Figure 3, the application can be applied to the application scene with faster response speed. The working principle of the whole software radio module 1 is as follows: after the software radio module 1 is connected to the power supply, the power amplification unit 112 and the signal processing unit 111 are powered on in turn. After the power-on is completed, the signal processing unit 111 and / or the power amplification unit 112 sends the power-on completion information to the control end through the first interface 121. The control end will then send an enable signal. After the power amplification unit 112 receives the enable signal through the first interface 121, it can start normal work and send the enable success information to the control end through the first interface 121. At the same time, the signal processing unit 111 can also complete the enablement by itself after monitoring that the control end sends the enable signal. After that, the power amplification unit 112 can perform power amplification on the initial signal transmitted by the signal processing unit 111 to obtain a radio frequency signal and transmit it through the antenna. At the same time, the control end can control different software radio modules 1 to work, so as to be able to transmit signals of different frequency bands, for example, it can interfere with different categories of unmanned aerial vehicles at the same time. In this embodiment, the control end can start the software radio module 1 of the corresponding frequency band by the enable signal, so as to be applicable to different unmanned aerial vehicle countermeasures scenes, and the control method is simple and convenient, so that each software radio module 1 can start working as soon as possible, thereby having a faster response speed.

[0040] Figure 4 is a logic structure diagram of a software radio module in an embodiment of the present application. The software radio module 1 of this embodiment includes a function module 11 and an interface assembly 12 connected electrically. The interface assembly 12 includes a second interface 122 and a third interface 123, which are, for example, RS422 interfaces, RS485 interfaces, CAN bus interfaces, RS232 interfaces or other interfaces similar in function to these interfaces (such as other types of interfaces capable of supporting serial communication). One end of the second interface 122 can be detachably connected electrically to the second connection end of the control end (not shown) or the third interface of the previous software radio module (not shown), and the other end of the second interface 122 is connected electrically to the function module 11, for directly receiving or receiving the control information of the control end through the previous software radio module and sending the control information to the function module 11. One end of the third interface 123 is connected electrically to the function module 11, and the other end of the third interface 123 can be detachably connected electrically to the second interface of the next software radio module or be suspended, for sending the control information of the control end to the next software radio module (not shown).

[0041] In this embodiment, one end of the second interface 122 of the software radio module 1 supports two connection modes (one is detachable electrical connection with the second connection end of the control terminal, and the other is detachable electrical connection with the third interface of the previous software radio module), and the specific connection mode depends on the position of the software radio module 1 in the cascade system (i.e. the system including the control terminal and multiple software radio modules 1). Among them, the previous software radio module will receive the control information of the control terminal earlier than the software radio module 1. The latter software radio module will receive the control information of the control terminal later than the software radio module 1. If the software radio module 1 is the first module in the cascade system, one end of the second interface 122 is detachably electrically connected with the second connection end of the control terminal, and the other end of the third interface 123 is detachably electrically connected with the second interface 122 of the latter software radio module. If the software radio module 1 is a module in the middle position in the cascade system, one end of the second interface 122 is detachably electrically connected with the third interface 123 of the previous software radio module, and the other end of the third interface 123 is detachably electrically connected with the second interface 122 of the latter software radio module. If the software radio module is the last module in the cascade system, one end of the second interface 122 is detachably electrically connected with the third interface 123 of the previous software radio module, and the other end of the third interface 123 is left dangling.

[0042] When the software radio module 1 needs to be controlled, the control terminal generates and sends the control information of the software radio module 1. If the software radio module 1 is the first module, the second interface 122 can directly receive the control information from the control terminal and send it to the functional module 11 to control the functional module 11. If the software radio module 1 is not the first module, each software radio module in front will in turn pass the control information from the control terminal to the rear until the control information reaches the second interface 122 of the software radio module 1, and the second interface 122 sends the control information to the functional module 11. In this embodiment, since the interface assembly 12 of the software radio module 1 includes the second interface 122 and the third interface 123, multiple software radio modules 1 can be connected in sequence by their respective second interfaces 122 and third interfaces 123, and the second interface 122 of the first software radio module 1 is electrically connected with the second connection end of the control terminal. Such a cascade connection mode can be called a chain cascade connection mode. In this chain cascade connection mode, since the control terminal only needs one output end, it can transmit more types and more complex data, thereby enabling the control terminal to control the software radio modules 1 more intelligently.

[0043] Figure 5 is a logical structure diagram of a software radio module in an embodiment of the present application. The software radio module 1 in this embodiment is a specific implementation of the embodiment shown in Figure 4. The control information includes an enable signal. The functional module 11 includes a signal processing unit 111 and a power amplification unit 112. The signal processing unit 111 is electrically connected to the second interface 122, the third interface 123, and the power amplification unit 112, respectively, and is configured to generate an initial signal upon receiving the enable signal. The power amplification unit 112 is electrically connected to the signal processing unit 111 and is configured to perform power amplification on the initial signal to generate a radio frequency signal upon receiving the enable signal.

[0044] In this embodiment, the control end can control the software radio module 1 to turn on or off. The specific control method is, for example, that an enable signal can be sent to the software radio module 1 that needs to work according to actual needs, and no enable signal needs to be sent to the software radio module 1 that does not need to work. At this time, the enable signal can be any type of signal. Alternatively, an enable signal can be sent to the software radio module 1 that needs to work, and a shutdown signal can be sent to the software radio module 1 that does not need to work (for example, the same pin is used for the enable signal and the shutdown signal, when the pin transmits a high level, it is considered to transmit the enable signal, and when the pin is low, it is considered to transmit the shutdown signal). The initial signal is, for example, a radio frequency signal with relatively low power, which can be a radio frequency signal modulated or modulated, up-converted, etc. after a drone jamming code generated or called for a certain frequency band drone. Moreover, different software radio modules 1 can output interference signals of different frequency bands. Therefore, by adopting multiple software radio modules 1, interference can be performed on different types of drones at the same time. In addition, in other embodiments, the control end can generate a drone jamming code of a corresponding frequency band and send the drone jamming code to the corresponding software radio module 1, and the software radio module 1 can modulate the drone jamming code to obtain the initial signal.

[0045] Moreover, the control end can simultaneously or sequentially enable the signal processing unit 111 and the power amplification unit 112 in the software radio module 1. The signal processing unit 111 and the power amplification unit 112 that are not enabled can enter a low-power state, for example, thereby further prolonging the service life of the software radio module 1.

[0046] Fig. 6 is a logic structure diagram of the software radio module in an embodiment of the present application. The software radio module 1 in this embodiment is a further specific implementation of the embodiment shown in Fig. 5. In this embodiment, the signal processing unit 111 further includes a processor 1111, for example, an FPGA, and a transceiver 1112. The processor 1111 is electrically connected to the second interface 122 and the third interface 123, respectively, and is configured to generate a source signal upon receiving an enabling signal. The transceiver 1112 is electrically connected to the processor 1111 and the power amplification unit 112, respectively, and is configured to modulate the source signal into an initial signal upon receiving the enabling signal. In this embodiment, the processor 1111 can generate a corresponding source signal (for example, a drone jamming code), and convert it into an initial signal through the transceiver 1112, for example, modulating the source signal onto a carrier wave of a specific frequency band, amplifying the initial signal through the power amplification unit 112, and outputting a corresponding radio frequency signal. It should be noted that in other embodiments, the transceiver 1112 can perform up-conversion on the modulated signal in addition to modulation. The up-converted signal is the initial signal. These are within the scope of the present application. For principles of modulation, up-conversion, etc., please refer to related technologies of wireless communication, which will not be described here.

[0047] Further, the control information further includes a parameter control signal, for example, a configuration signal for configuring a frequency band. It should be noted that the specific form of the configuration signal is not limited here, as long as the signal processing unit 111 can recognize it. The signal processing unit 111 is further configured to perform parameter configuration according to the parameter control signal. In this embodiment, the control end can configure the parameters of the signal processing unit 111 in each software radio module 1 to change the parameters of the processor 1111, and the processors 1111 in different software radio modules 1 can be correspondingly set to different parameters. For example, different software radio modules 1 correspond to different frequency bands. In addition, the control end can also control parameters such as bandwidth and signal content. For example, if a new drone is found in the environment, the software radio module 1 can be configured to generate a drone jamming signal that is compatible with the frequency band, bandwidth, etc. of the new drone, so that the new drone can also have a jamming signal. Or, if there are multiple types of drones in the current environment, the control end can control multiple software radio modules 1 to generate drone jamming signals corresponding to each drone, so that each type of drone in the current environment can be effectively jammed.

[0048] Further, the signal processing unit 111 is also configured to send the status information of the software radio module 1 to the control terminal through the second interface 122, and send the status information of other software radio modules received through the third interface 123 to the control terminal through the second interface 122. In the embodiment, each software radio module 1 can pass its status information to the control terminal through the previous software radio module in turn. The status information can be, for example, frequency band configuration information (e.g., indicating which frequency band of the unmanned aerial vehicle it interferes with) or enable completion information (i.e., indicating that it has started working). Further, each software radio module 1 does not need to set its ID, number or other identity information in advance, but can be automatically numbered after all the software radio modules 1 are cascaded. This automatic numbering method has no sequence limitation when each software radio module 1 is cascaded, so that the application of the software radio module 1 is more flexible.

[0049] For example, one specific transmission method of the status information is that the control information sent by the control terminal can include an acquisition information instruction. When all the software radio modules 1 are powered on and completed, the control terminal can send an acquisition information instruction to the first software radio module 1. After receiving the acquisition information instruction, the processor 1111 of the first software radio module 1 automatically generates an initial number (e.g., 1) and reports its number and status information to the control terminal through the second interface 122, and sends the acquisition information instruction and its number to the second software radio module 1 through the third interface 123. After receiving the acquisition information instruction and the number of the first software radio module 1, the second software radio module 1 automatically generates its own number (e.g., in an increasing order, such as 2), and then sends its number and status information to the first software radio module 1 through the second interface 122. The above process is repeated. Finally, the first software radio module 1 transmits the numbers and status information of all the software radio modules 1 received through the third interface 123 to the control terminal. The control terminal can know the number and corresponding status information of all the connected software radio modules 1. It can be understood that the software radio module 1 can also automatically upload its status information to the control terminal without receiving the acquisition information instruction, for example, it can automatically send its power-on completion information to the control terminal after being powered on. In this embodiment, the signal processing unit 111 of each software radio module 1 can send the status information to the control terminal directly or indirectly, so that the control terminal can know the status of each software radio module 1 in time.

[0050] Further, the control information further comprises software upgrade information, and the signal processing unit 111 is further configured to perform software upgrade according to the software upgrade information, for example, upgrade the stored drone jamming code, or upgrade the algorithm of the signal processing unit 111. In this embodiment, the control terminal can perform software upgrade on the signal processing unit 111 in each software radio module 1 according to actual needs, which is more convenient and efficient, and can improve the performance and signal decoding efficiency without the need to make substantial changes to the hardware circuit of the drone countermeasure system. Of course, in other embodiments, the software radio module 1 can also be upgraded by a dedicated device.

[0051] Fig. 7 is a logic structure diagram of the software radio module in an embodiment of the present application. The software radio module 1 in this embodiment comprises a functional module 11, an interface component (not shown), a first circuit board 13, a second circuit board 14, and a board-to-board connector 15 (BTB connector). The functional module 11 comprises a signal processing unit 111 disposed on the first circuit board 13 and a power amplification unit 112 disposed on the second circuit board 14. The first circuit board 13 and the second circuit board 14 are electrically connected through the board-to-board connector 15. The signal processing unit 111 and the power amplification unit 112 are respectively electrically connected with the board-to-board connector 15.

[0052] In this embodiment, the first circuit board 13 comprises the signal processing unit 111, i.e., the signal processing unit 111 can be composed of several devices (e.g., a processor 1111 and a transceiver 1112) on the first circuit board 13. The second circuit board 14 comprises the power amplification unit 112, i.e., the power amplification unit 112 can be composed of several devices (e.g., a power amplifier) on the second circuit board 14. The signal processing unit 111 and the power amplification unit 112 in the functional module 11 are respectively disposed on two different circuit boards, and the two circuit boards are stacked, so that the volume of the entire software radio module 1 can be reduced. In addition, the first circuit board 13 and the second circuit board 14 are connected through the board-to-board connector 15, and the volume of the board-to-board connector 15 is small, which facilitates the connection of the two stacked circuit boards, so that the volume of the entire software radio module 1 can be further reduced, and it is more convenient to integrate multiple software radio modules 1 in a product, thereby improving the degree of integration.

[0053] Further, besides the functional module 11 is dispersedly arranged on the two circuit boards, the interface assembly 12 can also be dispersedly arranged on the two circuit boards. Fig. 8 is a specific arrangement scheme of the software radio module 1 in the embodiment shown in Fig. 7. In this embodiment, the software radio module 1 comprises the functional module 11 (not shown), the interface assembly 12, the first circuit board 13, the second circuit board 14 and the board-to-board connector 15 (such as a BTB connector). The functional module 11 comprises the signal processing unit 111 and the power amplification unit 112. Moreover, the interface assembly 12 comprises the first interface 121 arranged on the second circuit board 14, and the second interface 122 and the third interface 123 arranged on the first circuit board 13.

[0054] In this embodiment, since the first interface 121 is used as the interface of the star-type cascade and is mainly used for enabling control of the power amplification unit 112 on the second circuit board 14 by the control terminal, arranging the first interface 121 on the second circuit board 14 can make the second circuit board 14 be used as an independent power amplifier board. Meanwhile, since the second interface 122 and the third interface 123 are used as the interfaces of the chain-type cascade and are mainly used for control of the signal processing unit on the first circuit board 13 by the control terminal, arranging the second interface 122 and the third interface 123 on the first circuit board 13 is more convenient for control of the signal processing unit 111 by the control terminal.

[0055] Further, as shown in Fig. 8, the interface assembly 12 further comprises a power supply interface 124, which is electrically connected with the functional module 11 and is used for inputting a power supply voltage and supplying power to the functional module 11. In this embodiment, the power supply interface 124 of each software radio module 1 is connected with a power supply, i.e., each software radio module 1 is independently powered, so that when a power supply fails in the star-type cascade mode, the work of other software radio modules 1 is not affected, and the reliability of the system is improved.

[0056] Further, as shown in FIG. 8, the power interface 124 is arranged on the second circuit board 14. The power interface 124 is electrically connected with the power amplification unit 112 and also supplies power to the devices on the first circuit board 13 through the board-to-board connector 15. In this embodiment, the power interface 124 is arranged on the second circuit board 14, which can make the second circuit board 14 work independently, i.e., the second circuit board 14 is used as a power amplifier board. On the other hand, since the current of the power amplification unit 112 is large and the main power supply object is the power amplification unit 112, arranging the power interface 124 on the second circuit board 14 can ensure that the power supply connected to the power interface 124 supplies power to the power amplification unit 112 first. When the power supply interface 124 of the software radio module 1 is connected to the power supply, the power supply supplies power to the power amplification unit 112 on the second circuit board 14 first, and then supplies power to the devices (including the signal processing unit 111) on the first circuit board 13 through the board-to-board connector 15. In this embodiment, the power supply can be a voltage power supply. When the voltage power supply supplies power to the devices on the first circuit board 13 and the second circuit board 14 through the power interface 124, the actual current size in the power supply path is determined by the power consumption of the devices. Since the power consumption of the power amplification unit 112 is large, the current of the connected power supply is also large. If the power interface 124 is arranged on the first circuit board 13, the voltage power supply needs to supply power to the power amplification unit 112 through the board-to-board connector 15, so a large current will flow through the board-to-board connector 15, which requires a high requirement for the board-to-board connector 15, increases the cost and occupies a large volume. In this embodiment, the power interface 124 is arranged on the second circuit board 14. Since the power consumption of the devices (such as the processor 1111) on the first circuit board 13 is small, the current of the voltage power supply provided for the first circuit board 13 is also small, so the board-to-board connector 15 will not pass a large current. In this embodiment, the power interface 124 only needs to output a small current to the first circuit board 13 through the board-to-board connector 15, and a large current only exists in the power supply path of the power interface 124 to the power amplification unit 112 on the second circuit board 14, so the above problem can be avoided.

[0057] Further, as shown in FIG. 8, the interface assembly 12 further includes a radio frequency output interface 125, which is electrically connected with the power amplification unit 112 and is used to output the radio frequency signal generated by the power amplification unit 112. In this embodiment, the radio frequency output interface 125 can be used to connect an antenna, i.e., in use, the antenna can be directly connected to the radio frequency output interface 125, which is more convenient for users to increase or decrease the software radio module 1 and the antenna according to actual needs.

[0058] Further, as shown in Fig. 8, the first interface 121, the second interface 122 and the third interface 123 are respectively arranged at the edge position of the corresponding circuit board, which is more convenient for cascading with the control terminal or other software radio module 1 (not shown). Similarly, the power interface 124 and the radio frequency output interface 125 are also arranged at the edge position of the second circuit board 14, which is more convenient for the access of the power supply and the antenna.

[0059] Fig. 9 is a logic structure diagram of the software radio module in an embodiment of the present application. In combination with the above-mentioned embodiments, the software radio module 1 of this embodiment includes the functional module 11, the interface assembly 12, the first circuit board 13, the second circuit board 14 and the board-to-board connector 15. The interface assembly 12 includes the first interface 121, the second interface 122, the third interface 123, the power interface 124 and the radio frequency output interface 125. The functional module 11 includes the signal processing unit 111 arranged on the first circuit board 13 and the power amplification unit 112 arranged on the second circuit board 14. The signal processing unit 111 includes the processor 1111 and the transceiver 1112 electrically connected. The processor 1111 is electrically connected with the second interface 122 and the third interface 123, and is also electrically connected with the first interface 121 through the board-to-board connector 15. The transceiver 1112 is electrically connected with the processor 1111, and is also electrically connected with the power amplification unit 112 through the board-to-board connector 15. The first circuit board 13 and the second circuit board 14 are electrically connected through the board-to-board connector 15. The board-to-board connector 15 includes the digital board-to-board connector 151 and the radio frequency board-to-board connector 152. The radio frequency board-to-board connector 152 is electrically connected with the transceiver 1112 and the power amplification unit 112, respectively. The digital board-to-board connector 151 is electrically connected with the processor 1111, the power amplification unit 112 and the first interface 121, respectively. As shown in Fig. 9, the digital board-to-board connector 151 is also electrically connected with the power interface 124 and the power supply circuit 113, respectively. The software radio module 1 of this embodiment can support two kinds of cascading modes: the star cascading mode and the chain cascading mode.

[0060] For the star cascade mode, when the control end is connected to the first interface 121 of each software radio module 1 through the corresponding first connection end, the star cascade mode can be constructed. Since the first interface 121 of each software radio module 1 is also connected to the power amplification unit 112 of itself and connected to the processor 1111 through the digital board-to-board connector 151, the enable signal, the state information, the operation instruction information, etc. can be transmitted. In this way, the control end can obtain the state of the software radio module 1 and can also control the enable of the software radio module 1 individually. Specifically, after the power amplification unit 112 is initialized, the processor 1111 and / or the power amplification unit 112 outputs a high-level state signal to the control end through the first interface 121. After receiving the high-level state signal, the control end can output an enable signal to the power amplification unit 112 under the manual trigger of the operator or automatically to trigger the enable of the power amplification unit 112. After the power amplification unit 112 is successfully enabled, an operation instruction signal is fed back to the control end through the first interface 121. After receiving the operation instruction signal, the control end can know that the power amplification unit 112 has been enabled. After that, the software radio module 1 can start working. In practical applications, the control end can control multiple software radio modules 1 to start working to simultaneously transmit signals of different frequency bands. Under the star cascade control mode, the control mode of the control end for each software radio module 1 is simple and efficient, which can improve the starting efficiency of the overall system.

[0061] For the chain cascade mode, the second connection end of the control end is connected with the second interface 122 of the first software radio module 1, the third interface 123 of the first software radio module 1 is connected to the second interface 122 of the second software radio module 1 through a corresponding connection line, and so on until the second interface 122 of the last software radio module 1, and the third interface 123 of the last software radio module 1 is left hanging. In this way, the chain cascade mode can be constructed. After power-on, the control end sends an acquisition information instruction to the first software radio module 1, the processor 1111 of the first software radio module 1 receives the instruction and automatically generates a number, and reports the information of the number of the software radio module 1 and the frequency band configuration information and the like to the control end, while forwarding the instruction of the control end to the second software radio module 1 through the third interface 123 and sending the current software radio module number. The second software radio module 1 automatically generates its own number after receiving the instruction and the number of the first software radio module 1, and replies the state information of itself with the number and the frequency band configuration information and the like through the second interface 122, and forwards the instruction of the control end through the third interface 123 and sends the current software radio module number to the third software radio module, and so on until the last software radio module 1. The first software radio module 1 returns all the software radio module numbers + information to the control end through the second interface 122. Through the second interface 122 and the third interface 123 of each software radio module 1, the chain cascade mode enables the control end to acquire the number of all the currently connected software radio modules 1 and the frequency band configuration corresponding to the software radio modules 1 and the like, and can send corresponding instructions to control whether the corresponding software radio modules 1 are turned on or not. In addition, the control end can also change the control parameters of the processor 1111 in each software radio module 1 to change the parameters of the final output signal (such as the content of the interference code and the bandwidth of the interference signal). In addition, in the chain cascade mode, the control end can also perform software upgrade on the processor 1111 in the corresponding software radio module 1 through the second interface 122 and the third interface 123, so that the software radio module 1 supports software upgrade iteration, that is, without changing the hardware, the interference signal can be adjusted according to the unmanned aerial vehicle communication protocol. Of course, in other embodiments, the processor 1111 of the software radio module 1 can also be upgraded by a dedicated device.

[0062] From the above, the three signals of the enable signal, the state signal, and the operation indication signal can be used for both the star-type cascade control and the chain-type cascade control, and the functions of the three signals are basically the same, with the difference being that, in the star-type cascade mode, the control end directly communicates data with the signal processing unit 111 and the power amplification unit 112 of the corresponding software radio module 1 through the first interface 121 on each software radio module 1. In the chain-type connection mode, the control end communicates data with the signal processing unit 111 and the power amplification unit 112 in each software radio module 1 through the second interface 122 and the third interface 123 of each software radio module 1. In addition, in this embodiment, the enable signal, the state signal, the operation indication signal, and the control signal can be signals matched with preset level values and preset signal types, which are not specifically limited here.

[0063] In addition, in the star-type cascade mode, since the control end mainly controls the switches of the software radio modules 1, the cost is low, the operation mode is simple, and the operation efficiency is high, and it is suitable for the integration of some simple systems. In the chain-type cascade mode, the control end can not only control the switches of the software radio modules 1, but also flexibly change the configuration parameters of the software radio modules 1, so the operation mode is more intelligent. Moreover, since only one connection end of the control end is used in the chain-type cascade mode, the interface design of the control end is simplified. The software radio module 1 of this embodiment can support both the two cascade modes, so the applicable use scenarios are more extensive.

[0064] It should be understood that, in some applications, if the star-type cascade control mode needs to be applied, the first interface 121 of each software radio module 1 can be directly connected to the corresponding first connection end of the control end, and the second interface 122 and the third interface 123 of each software radio module 1 are in an unconnected state. If the chain-type cascade control mode needs to be applied, the first interface 121 of each software radio module 1 can be in an unconnected state, and the second interface 122 and the third interface 123 of each software radio module 1 are sequentially connected and form a chain structure with the control end. Of course, in some applications, the star-type cascade control mode and the chain-type cascade control mode can be applied at the same time, or a part of the software radio modules 1 can be constructed into the star-type cascade control mode, and another part of the software radio modules 1 can be constructed into the chain-type cascade control mode.

[0065] Further, as an embodiment, the first interface 121 is, for example, an I / O control interface, the second interface 122 is, for example, an RS422 input port, and the third interface 123 is, for example, an RS422 output port, as shown in FIG. 9. In this embodiment, since the RS422 interface has excellent anti-interference performance, the accuracy of the communication signal can be ensured in a complex radio frequency signal environment.

[0066] Further, as shown in FIG. 9, the power interface 124 is arranged on the second circuit board 14, and the power interface 124 is electrically connected with the power amplification unit 112 and is also electrically connected with the signal processing unit 111 through the board-to-board connector 15 (digital board-to-board connector 151). In addition, the functional module 11 further comprises a power supply circuit 113, which is electrically connected with the digital board-to-board connector 151. The power supply circuit 113 is used for voltage conversion of the input power voltage and power supply for each device of the first circuit board 13 (including the signal processing unit 111). The power supply circuit 113 is, for example, a voltage conversion circuit. In addition, when the power interface 124 is arranged on the second circuit board 14, since the power amplification unit 112 is powered first, and the signal processing unit 111 is powered after a period of time, after the signal processing unit 111 is powered, the processor 1111 can send a signal for indicating that the power-on is completed to the first interface 121 through the digital board-to-board connector 151. In this embodiment, the power amplification unit 112 is also electrically connected with the transceiver 1112 through the board-to-board connector 15 (radio frequency board-to-board connector 152). After the signal processing unit 111 is enabled, the processor 1111 generates a source signal, and converts the source signal into an initial signal through modulation and other processing of the transceiver 1112, and then sends the initial signal to the power amplification unit 112 through the radio frequency board-to-board connector 152, and the power amplification unit 112 amplifies the initial signal and outputs a radio frequency signal.

[0067] Further, in some embodiments, the software radio module 1 can be wrapped by metal aluminum material, so that good heat dissipation and signal shielding can be provided, thereby improving the working performance.

[0068] The embodiments of the present application also provide a UAV countermeasure system, which comprises the above-mentioned software radio module 1, and the logical structure of the software radio module 1 can refer to the foregoing embodiments, which will not be described herein.

[0069] FIG. 10 is a logical structure diagram of a UAV countermeasure system in an embodiment of the present application. The UAV countermeasure system in this embodiment comprises a control end 2 and a plurality of software radio modules 1. The control end 2 is, for example, a single-chip microcomputer. Taking one of the software radio modules 1 as an example, as shown in FIG. 2, the software radio module 1 comprises a functional module 11 and an interface assembly 12, and the interface assembly 12 comprises a first interface 121, which is, for example, an I / O control interface. In combination with FIG. 2 and FIG. 10, the control end 2 comprises a plurality of first connection ends, and the first interfaces 121 of the plurality of software radio modules 1 are electrically connected with the plurality of first connection ends one by one in a detachable manner. It should be understood that in other embodiments, the number of the software radio modules 1 can also be only one.

[0070] In this embodiment, the control end 2 can be connected with the plurality of software radio modules 1 through the plurality of first connection ends respectively, so as to build the UAV countermeasure system in a star type cascade. This connection mode has low cost and simple operation mode.

[0071] In this mode, the control end 2 can control the plurality of software radio modules 1 simultaneously. When the control end 2 and the plurality of software radio modules 1 build the UAV countermeasure system in a star type cascade, the control end 2 can output control information to the first interface 121 of the corresponding software radio module 1 under automatic triggering or manual triggering of the operator, so as to control the function module 11 correspondingly. After the function module 11 is executed according to the control information, the function module 11 will feed back a running indication signal to the control end through the first interface 121. The control end 2 can know that the function module 11 has been controlled after receiving the running indication signal. The function module 11 will also send state information to the control end 2 through the first interface 121, and the control end 2 can know the state information of the function module 11 after receiving the state information.

[0072] FIG. 11 is a logic structure diagram of the UAV countermeasure system in an embodiment of the present application. The UAV countermeasure system in this embodiment includes the control end 2 and the plurality of software radio modules 1. The control end 2 is, for example, a single-chip microcomputer. As shown in FIG. 4, the interface assembly 12 includes the second interface 122 and the third interface 123. In combination with FIG. 4 and FIG. 11, the control end 2 includes the second connection end, the second interface 122 of the first software radio module 1 is detachably electrically connected with the second connection end of the control end 2, the third interface 123 of the first software radio module 1 is detachably electrically connected with the second interface 122 of the second software radio module 1, the second interface 122 of the intermediate software radio module 1 is detachably electrically connected with the third interface 123 of the previous software radio module 1 of the software radio module 1, the third interface 123 of the intermediate software radio module 1 is detachably electrically connected with the second interface 122 of the next software radio module 1 of the software radio module 1, and the third interface 123 of the last software radio module 1 is suspended. The intermediate software radio module 1 is the other software radio module 1 except the first software radio module 1 and the last software radio module 1 among all the software radio modules 1.

[0073] Of course, it can be understood that the number of the software radio modules 1 can also be two or one. If the number is two, there is no above-mentioned intermediate software radio module 1. If the number is one, there is only the above-mentioned first software radio module 1.

[0074] In this embodiment, all the software radio modules 1 can be connected in series through the respective second interfaces 122 and third interfaces 123, and the second interface 122 of the first software radio module 1 is electrically connected with the second connection end of the control terminal 2. In this way, the control terminal 2 can be connected with the plurality of software radio modules 1 to form a chain-cascaded UAV countermeasure system. This connection mode enables the control terminal 2 to not only control the opening or closing of any software radio module 1, but also flexibly change the interference code and bandwidth and other parameters, thus being more intelligent.

[0075] In this mode, the control terminal 2 can also control a plurality of software radio modules 1 at the same time. After being powered on, the control terminal 2 sends an acquisition information instruction to the first software radio module 1. The processor 1111 of the first software radio module 1 receives the instruction and reports the information of the number of the software radio module 1 and the frequency band configuration information to the control terminal 2. Meanwhile, the processor 1111 forwards the instruction of the control terminal to the second software radio module 1 through the third interface 123 and sends the number of the current software radio module 1. After receiving the instruction and the number of the first software radio module 1, the second software radio module 1 replies the state information of itself with the number and the frequency band configuration information through the second interface 122, forwards the instruction of the control terminal 2 through the third interface 123, and sends the number of the current software radio module 1 to the third software radio module 1. This process is repeated until the last software radio module 1. The first software radio module 1 transmits the numbers and information of all the software radio modules 1 back to the control terminal 2 through the second interface 122. In this chain-cascaded mode, the control terminal 2 can acquire the number of all the software radio modules 1 connected and the frequency band configuration information of the software radio modules 1 through the second interfaces 122 and the third interfaces 123 of the software radio modules 1, and send corresponding instructions to control whether the corresponding software radio modules 1 are started. The control terminal 2 can also change the control parameters of the processors 1111 of the software radio modules 1 to change the parameters of the final output signal (such as the content of the interference code and the bandwidth of the interference signal). In addition, in the chain-cascaded mode, the control terminal 2 can also perform software upgrade on the processors 1111 of the corresponding software radio modules 1 through the second interfaces 122 and the third interfaces 123, so that the software radio modules 1 support software upgrade iteration, that is, the interference signal can be adjusted according to the UAV communication protocol without changing the hardware. Of course, in other embodiments, the processors 1111 of the software radio modules 1 can also be upgraded by a dedicated device.

[0076] The UAV countermeasure system constructed in the embodiment can simultaneously launch multiple interference signals (for example, interference signals of different frequency bands) to perform communication interference on different types of UAVs. Meanwhile, the UAV countermeasure system can increase or decrease the number of software radio modules 1 according to the number of frequency bands, realize one frequency band corresponding to one module, and in the case of adding a UAV frequency band, directly add a module without involving large changes of the system, so that the upgrade iteration is convenient and fast.

[0077] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not conflict, they should be considered within the scope of the present disclosure.

[0078] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
