Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

At present, most civilian drones use radio technology to achieve positioning, remote control and image transmission functions, such as positioning, remote control and image transmission through wireless working signals. Therefore, the use of radio interference technology to interfere with the drone can achieve the purpose of causing the drone to lose control or return to the air, that is, to send an interference signal to the drone to interfere with the drone.

In the prior art, two methods are mainly used to interfere with the unmanned aerial vehicle: wideband interference and narrowband frequency sweeping. Wideband interference is when an interfering device transmits an interfering signal over a large bandwidth, so that the transmit power of the interfering device is allocated to this larger bandwidth. Thus, in the actual interference process, the transmission power of the frequency band covering the wireless working signal of the drone will be relatively small, the energy concentration of the interference signal is low, and the effect on the wireless working signal of the drone is not good. In addition, when broadband interference is performed, the bandwidth covered by the interference signal is large, so interference with other electronic devices that are in use is caused, and environmental friendliness is poor.

The narrowband sweep is to transmit the interference signal by sweeping in a bandwidth range. Although the signal energy is concentrated, the interference signal is blindly scanned (for example, according to a certain step sequence or according to a certain rule), thus, no The interference time of the wireless working signal of the man-machine is very short, and the interference effect is poor. Currently, some interfering devices achieve multiple interferences in one bandwidth range by reducing the frequency of the sweep period. However, speeding up the frequency sweeping cycle will increase the difficulty of implementing the interference device and increase the hardware cost of the interference device. In addition, the frequency sweeping cycle is accelerated, and the effective interference time of the interference frequency band is further reduced, and the interference effect is also unsatisfactory.

The wireless working signals of the drone generally work in the ISM (Industrial Scientific Medical) band, and there may be other electronic devices in this band. Wideband interference and narrowband sweeping will affect other electronic equipment operating in this frequency band. Moreover, both broadband interference and narrowband frequency sweeping are persistent interferences, which will seriously affect the electromagnetic environment around the interference equipment and affect other The normal movement of electronic equipment. In addition, the transmission of the wireless working signal of the UAV currently adopts the frequency hopping transmission technology, which further improves the interference difficulty and reduces the interference effect of the interference device on the UAV.

According to the analysis of the prior art, the interference device does not analyze the signal characteristics of the wireless working signal of the drone, and the signal characteristics of the generated interference signal do not match the signal characteristics of the wireless working signal of the drone. Poor interference effects can also affect the operation of other electronic devices in the environment. In the embodiment of the present invention, before the wireless working signal of the drone is interfered, the wireless working signal of the drone is analyzed to obtain the signal characteristic of the wireless working signal. An interference signal that matches a signal characteristic of the wireless operational signal is generated for the signal characteristic. This can improve the interference effect and effectively reduce the impact on the surrounding electromagnetic environment.

In some embodiments, the specific step of controlling the interference device to send the interference signal is as shown in FIG. 4, and may include:

Step S401: Control the interference device to continuously transmit the interference signal for a preset length of time;

Specifically, the interference device is controlled to continuously transmit the interference signal for a preset length of time. The size of the preset time length can be set by the user. Alternatively, the preset time length may be determined according to a first signal characteristic of the wireless working signal.

For the specific determination method, refer to the foregoing part, when the preset working frequency is used. When the second signal characteristic of the wireless signal transmitted at each frequency point of the point does not meet the first preset requirement, it is determined that the wireless working signal of the drone is not found, and the detector continues to scan the preset working frequency point. Determining a first signal characteristic of the wireless working signal transmitted at the working frequency point, determining an interference signal generated by the interference device according to the first signal feature, and controlling the interference device to be in a preset time length The interference signal is continuously sent, and after the preset time length ends, the control interference device pauses to send the interference signal, acquires a wireless working signal transmitted on the target working frequency point, and determines a third signal of the wireless working signal. And when the third signal feature meets the second preset requirement, the interference device is controlled to generate an interference signal according to the first signal feature, and the interference device is controlled to continuously transmit the interference signal for a preset time length, and is repeated. Performing the above process until the third signal characteristic of the wireless working signal does not meet the second preset requirement, indicating that the interference of the wireless working signal on the working frequency point has been completed. At this point, the processor can control the detector to re-scan the preset working frequency point and repeat the above process. In this way, the tracking interference of the wireless working signal can be realized, the interference effect is good, and the influence on other electronic devices in the surrounding environment can be minimized.
