Embodiment 1, as shown in Figure 1, this application provides a method and system for dynamic monitoring and adjustment of the operating status of drone interference equipment. The method includes:

Build a space domain based on drone interference equipment, which is configured based on the radio frequency range of the equipment;

The spatial domain of the UAV interference device refers to the working range of the UAV interference device, which is set according to the radio frequency range of the UAV interference device. Among them, the radio frequency range is an important indicator of the interference capability of UAV interference equipment. When building the space domain, it is necessary to ensure that the radio frequency range can cover the interference range of the UAV to ensure that the UAV can be interfered. The radio frequency range of the UAV interference equipment is obtained, and the spatial range of the UAV interference equipment is set according to the equipment range of the UAV to obtain the spatial domain of the UAV interference equipment. The spatial domain of the UAV interference equipment can be arbitrarily divided according to the radio frequency range of the equipment, and the corresponding spatial domain of the UAV interference equipment can be constructed according to the actual situation. After determining the coordinate system, the spatial coordinate system is obtained and generated according to the spatial coordinate system. Corresponding coordinate space, output the coordinate space to obtain the spatial domain of the drone interference device. The acquisition of the spatial domain provides a data basis for subsequent detection space constraints based on the spatial domain. Combined with the detection operation control module, target identification is performed through radio detection of UAV jamming equipment, and identification responses are generated.

Based on the detection space constraints in the spatial domain, combined with the detection operation and control module, target identification is performed through radio detection of UAV jamming equipment, and an identification response is generated. The detection operation and control module is used to control the UAV interference equipment to perform radio detection. ;

The detection space constraint based on the spatial domain is a constraint that uses physical space information to constrain detection and identification. When the UAV jamming equipment interferes with the UAV, it cannot interfere with all objects in the spatial domain. This is too efficient. Low, the interference is limited, the interference of the drone is carried out in a set way, and the radio detection of the detection operation control module and the drone jamming equipment can be combined to achieve more efficient and accurate target identification. Among them, the detection operation control module is used to control the UAV jamming equipment to conduct radio detection, and perform target identification through the radio detection of the UAV interference equipment. After the radio detection completes the target identification, the target identification result is obtained, and the target identification result is Obtain and generate a corresponding recognition response based on the target recognition result, indicating that the target is a UAV, and with the subsequent receipt of the recognition response, the interference operation control module is activated synchronously, and an interference scheme based on the interference mode is configured, where the interference mode Including forced landing mode, return mode and flight control interference mode to provide data basis.

With the reception of the identification response, the interference operation control module is activated synchronously and an interference scheme based on interference modes is configured. The interference modes include forced landing mode, return mode and flight control interference mode. The interference operation control module uses Correspond to the receiving identification, judge the current interference mode and configure the interference plan;

After receiving the identification response, the interference operation control module is activated. The interference operation control module is used to receive the identification response, judge the current interference method, obtain the judgment result, and configure the interference plan according to the judgment result. Construct an interference scheme database. There are multiple interference schemes in the interference scheme database. Users can select the interference mode according to the actual situation, confirm the current interference mode, and select the interference scheme accordingly according to the interference mode to complete the interference scheme. Configuration. There are three interference modes: forced landing mode, return mode and flight control interference mode. The forced landing mode interferes with the signal of the UAV and makes the UAV land rapidly; the return mode interferes with the direction of the UAV and causes it to land rapidly. The drone is driven away and leaves the space domain of the drone interference device; the flight control interference mode is to interfere with the flight control of the drone, causing the drone to become unstable during flight and crash. The determination of the interference plan provides a data basis for subsequent tracking and positioning of the target UAV, combined with the interference space constraints in the space domain, radio countermeasures for the target UAV based on the interference plan, and determining the actual situation of target interference.

Track and locate the target UAV, combine the interference space constraints in the space domain, conduct radio countermeasures for the target UAV based on the interference plan, and determine the actual situation of target interference;

To track and locate the target UAV, it is necessary to collect the position information of the target UAV, obtain the speed and direction information of the target UAV, determine the position of the UAV through GPS, and obtain the UAV position information through The position information calculates the speed of the target UAV to obtain the speed information of the target UAV, and determines the direction information of the target UAV based on the speed information to obtain the direction information. Based on the position information and speed information of the target UAV, and direction information to track and locate the target drone. The interference space constraints in the space domain are obtained, and the interference signal is emitted to the target UAV according to the interference space constraints in the space domain. The signal emission direction and signal dose are controlled according to the interference space constraints in the space domain, so that the emission direction and emission dose are Achieve the preset interference effect, monitor the interference process, determine the actual target interference, and provide a data basis for subsequent extraction of echo feedback signals and operating status evaluation based on the recognition response and the actual target interference, and determine the braking off-axis degree.

Based on the recognition response and the target interference situation, the echo feedback signal is extracted and the operating status is evaluated to determine the braking off-axis degree, which is the difference between the expected control effect and the actual control effect. ;

Evaluate the operating status of the interfered UAV, determine the interference situation of the interfered UAV, and extract the echo feedback signal. The echo feedback signal includes the reflected signal of the interfered UAV and the interference signal of the UAV jamming equipment. A mixed signal that emits a signal. By identifying the response and target interference live analysis results, the echo feedback signal is extracted, the echo feedback signal is obtained, the echo feedback signal is signal processed, the signal processing result is obtained, and the echo feedback signal of the signal processing result is processed Feature extraction to obtain the signal characteristics of the echo feedback signal. Evaluate the signal characteristics of the feedback signal. The evaluation indicators include interference effects, power consumption, stability, etc. Based on the operating status evaluation effect, the braking off-axis degree is determined, where the braking off-axis degree refers to the expected control effect. The difference between the actual control effect. The determination of the braking off-axis degree provides a data basis for tracing the source of the braking off-axis degree and determining the operating disturbance factors that indicate the degree of disturbance if the braking off-axis degree does not meet the threshold standard.

If the braking off-axis degree does not meet the threshold standard, trace the source of the braking off-axis degree and determine the operating disturbance factors marked with the degree of disturbance;

Set the braking off-axis threshold. The braking off-axis threshold is the minimum qualifying standard for braking off-axis. If it is lower than the braking off-axis threshold, it means that the current UAV interference device has poor interference effect on the UAV. It is necessary to Make adjustments to the drone jamming equipment. When the braking off-axis degree does not meet the braking off-axis degree threshold, the source of the braking off-axis degree is traced, that is, the echo feedback signal in the braking off-axis degree is obtained, and the error that causes the echo feedback signal is detected. Obtain the parameters of the human-machine interference equipment and analyze the causes to obtain the causes of the echo feedback signals, that is, operating disturbance factors, and extract features of the disturbance factors based on the operating disturbance factors to obtain the characteristics of the disturbance factors and analyze the disturbance factors The characteristics of the system are used to judge the degree of disturbance, obtain the degree of disturbance of the disturbance factors, and obtain the operating disturbance factors with disturbance degree identification. The acquisition of operational disturbance factors provides a data basis for subsequent adaptive operation control of UAV interference equipment based on operational disturbance factors.

Based on the operation disturbance factors, adaptive operation control of the UAV interference equipment is performed.

UAV interference equipment is regulated accordingly based on operational disturbance factors. There are many operational disturbance factors, such as ambient temperature, wind speed, air pressure, UAV type, etc. For example, in a scene with high wind speed, The drone will be unstable and unable to maintain a stable position, causing the drone jamming equipment to be unable to stably and accurately interfere with the target drone. When the drone is a type of drone with strong anti-interference ability , the power consumption of the required drone interference equipment will also increase, and the interference effect will decrease accordingly. Different operation control methods are required for different operation disturbance factors. The operation control methods include but are not limited to adjusting the signal frequency. Different UAVs use different communication signal frequencies. By adjusting the signal frequency of the interference equipment, the control method can be achieved. Effective interference of different drones; control signal power: too large a signal power may cause interference to other electronic equipment, while too small a signal power may not have an effective impact on the drone. The signal power needs to be flexibly adjusted according to the actual situation; adjustment Interference mode: Select the appropriate interference mode according to the type and number of drones. For example, for a group of UAVs, the cooperative interference mode can be used, and for a single UAV, the directional interference mode can be used. Analyze the operating disturbance factors, obtain the operation control methods corresponding to the operation disturbance factors, and complete the adaptive operation control of the UAV interference equipment, which can further improve the interference effect of the UAV interference equipment and improve the UAV's interference efficiency.

Furthermore, the method further includes:

Use the layout space of the drone interference equipment as the benchmark and the equipment layout position as the origin to determine the spatial axis;

Build a spatial coordinate system based on the spatial axis, perform longitude and latitude positioning fitting on the spatial coordinate system, and determine the fitting coordinate system;

Read the detection range and interference range of the UAV interference device, perform spatial constraints on the fitting coordinate system, and generate the spatial domain.

When generating a spatial domain, it is necessary to first establish a coordinate system and generate the spatial domain according to the coordinate system. Generating the spatial domain according to the coordinate system can position the UAV in the spatial domain and provide a basis for subsequent operations on the UAV. Location tracking provides the data foundation. Set the layout position of the UAV interference equipment as the origin of the coordinates, take the plane where the UAV interference equipment is located as the horizontal plane, use the horizontal plane as the benchmark to confirm the spatial axis, construct the Z-axis perpendicular to the horizontal plane, and perform corresponding operations based on the Z-axis The X-axis and Y-axis are constructed, and the X-axis and Y-axis are in the horizontal plane. Coinciding the X-axis and Y-axis of the spatial coordinate system with the longitude and latitude of the earth, complete the positioning coincidence of the longitude and latitude of the spatial coordinate system, and obtain the coincidence result, which is useful for you and The coordinate system is determined. Then obtain the detection range of the UAV jamming equipment, take the origin as the center of the circle in the fitting coordinate system, take the detection range of the UAV interference equipment as the radius, construct a sphere in the fitting space coordinate system, and obtain the is a hemisphere, and the internal range of the hemisphere is the actual detection range; in the same way, the interference range of the UAV interference device is obtained. In the fitting coordinate system, the origin is the center of the circle, and the interference range of the UAV is The interference range of the device is the radius. Construct a sphere in the fitting space coordinate system to obtain the hemisphere on the ground. The internal range of the hemisphere is the actual interference range. That is, the spatial constraints on you and the coordinate system are completed, and the spatial domain is obtained. , the spatial domain includes the actual detection range and the actual interference range. The generation of the spatial domain provides a data basis for subsequent detection space constraints based on the spatial domain.

Furthermore, the method further includes:

Configure an interference database, wherein the interference database includes multiple sequences characterized by interference patterns-pre-interference schemes that have a one-to-many relationship;

With the identification response as a constraint and the interference pattern as a requirement, the interference database is traversed for matching to determine the interference plan.

When determining the interference scheme, it is necessary to organize the interference scheme, establish an interference scheme database, and establish the corresponding relationship between each data scheme in the interference database. According to the identification response, traverse the interference scheme database to obtain the corresponding interference scheme. Improve the efficiency of determining interference plans and further improve the efficiency of the overall system. Construct a corresponding relationship between the interference mode and the interference plan. Since the interference plan has not yet been executed, the interference plan is used as the pre-interference plan to obtain the interference mode-pre-interference plan sequence. For example, the interference modes are divided into forced landing mode, return mode and flight control interference mode. Among them, the interference methods corresponding to the return mode include GPS suppressive interference, that is, transmitting high-power signals with the same frequency as GPS satellites, making the UAV GPS The receiver module is saturated, causing the UAV to make an emergency landing; it also corresponds to blocking interference. Blocking interference uses noise signals to disrupt the other party's receiver, achieving complete coverage of the echo in the time domain, frequency domain, and transform domain. , so that the other party's radar cannot capture effective echo information and complete the emergency landing of the UAV. Multiple interference pattern-pre-interference scheme sequences are obtained, and the multiple interference pattern-pre-interference scheme sequences are combined into an interference database. Extract features based on the recognition response, perform feature matching on the interference pattern based on the identified corresponding features, obtain the matching results, traverse the interference database based on the matching results, obtain the matching interference patterns, and obtain the matching interference patterns based on the multiple sequences corresponding to the interference patterns. The interference plan can improve the efficiency of determining the interference plan and further improve the efficiency of the overall system.

Furthermore, the method further includes:

The echo feedback signal is transmitted to the operation control deviation traceability module, and the module is independently analyzed to determine the single traceability result, where the single traceability result corresponds to each analysis module one-to-one;

Perform in-line fitting on the single traceability results to determine the operating disturbance factors.

There are many reasons for the off-axis braking of UAV interference equipment, including the UAV itself having a certain anti-interference ability, the control deviation of the UAV interference equipment itself, and the magnetic field in the working environment of the UAV interference equipment. Interference, in view of the reasons for the braking off-axis degree of the UAV interference equipment, corresponding solution modules are generated to solve the corresponding problems, namely the anti-interference analysis module, the operation control deviation analysis module and the environmental field interference analysis module. The anti-interference analysis module, operation control deviation analysis module and environmental field interference analysis module are combined to build an operation control deviation traceability module. The operation control deviation traceability module performs braking off-axis analysis based on the received echo feedback signal. The echo feedback signal is sent to the three analysis modules in the operation control deviation traceability module.

The UAV interference log includes a large number of radio frequency signals, echo feedback signals and anti-interference data, among which The sample anti-interference data is the overall data generated when interfering with the drone. Different interference situations correspond to different anti-interference data. Different analysis modules can be constructed based on different anti-interference data to combine the data in the drone interference log. Radio frequency signals, echo feedback signals and anti-interference data are extracted to obtain sample radio frequency signals, sample echo feedback signals and sample anti-interference data.

The generation of the anti-interference analysis module is for subsequent configuration of the operation control deviation traceability module. The echo feedback signal is transmitted to the operation control deviation traceability module, and the module is independently analyzed to determine the single traceability result. Among them, the single traceability result is consistent with each analysis module. One-to-one correspondence provides data basis.
