[0015] Embodiment 1

[0016] The present application is described in detail below with reference to the accompanying drawings. Figure 1 As shown, the present application provides a multi-band UAV intelligent interference control module, which includes:

[0017] The communication grid establishment unit M100 is used to establish a low-altitude communication grid according to the communication connection between the target UAV and the terminal control center, wherein the low-altitude communication grid includes multiple communication links, and each communication link is configured within the initial frequency band interval; the continuous spectrum scanning unit M200 is used to use a high-speed voltage-controlled oscillator to perform continuous spectrum scanning within the initial frequency band interval to collect a real-time monitoring signal set, wherein the real-time monitoring signal set includes a UAV control signal subset, an image transmission signal subset, and a positioning signal subset; the communication planning unit M300 is used to use the multiple communication links in the low-altitude communication grid as the communication interaction sagittal axis direction, perform communication planning according to the UAV control signal subset, the image transmission signal subset, and the positioning signal subset, and establish a low-altitude communication corridor, wherein the low-altitude communication corridor avoids sensitive areas and potential interference sources within the coverage range of the low-altitude communication grid.

[0018] Specifically, the communication grid refers to the low-altitude communication structure established through the communication link between the target UAV and the terminal control center. In this grid, each node represents a communication link to ensure smooth data transmission between the UAV and the control center; the communication link refers to the wireless signal channel connecting the UAV and the control center, which is used for the transmission of data, control instructions, images and other information. The frequency band of each link is fixed and initially configured within a certain frequency band range; the frequency band interval refers to the frequency range used by wireless communication equipment. Usually, a frequency band interval represents a series of frequency values, and the equipment sends and receives signals within this range; continuous spectrum scanning refers to continuous scanning within a certain frequency range to collect all signals operating in this frequency band. This process uses a high-speed voltage-controlled oscillator (VCO), which is an electronic component used to change the frequency; UAV control signal subset, image transmission signal subset, positioning signal subset: During the continuous spectrum scanning process, the system will classify the collected signals into corresponding subsets according to different functions such as UAV control, image transmission and positioning; the low-altitude communication corridor refers to one or more communication links determined in the communication grid, avoiding interference and sensitive areas to ensure that the communication between the UAV and the control center is not affected.

[0019] Execution steps: By detecting the communication signals between the drone and the control center, a low-altitude communication grid is constructed. This grid is like a detailed map. All nodes represent the communication points between the drone and the control center. The grid contains multiple communication links, and each link is initially configured in a specific frequency band range, such as 2.4GHz or 5.8GHz, which are common wireless communication frequency bands; in order to monitor and control the communication of the drone, the system starts continuous spectrum scanning. By using a high-speed voltage-controlled oscillator (VCO), the system can quickly scan the target frequency band range and detect all signals within this range. This process is similar to looking for the signal of a radio station on the radio, except that what needs to be detected here are signal subsets such as control signals, image transmission signals, and positioning signals. For example, when a drone sends real-time images, the image transmission signal will be classified into the image transmission signal subset, while the signal that controls its flight direction belongs to the drone control signal subset. These signals are continuously collected and monitored to determine the frequency and strength used by each signal.

[0020] After collecting all necessary signal subsets, communication planning is required. The core of communication planning is to accurately locate the communication path between the drone and the control center, so that the communication link avoids the interference area as much as possible to ensure smooth communication. Generally speaking, if an illegal drone is flying over a sensitive area and there are potential interference sources nearby (such as other electromagnetic equipment), these interference sources will be identified in advance to avoid them, and a communication path to avoid interference will be calculated, which is called a low-altitude communication corridor. This corridor is equivalent to a dedicated channel for drone communication and can avoid interference. The communication planning unit uses multiple communication links in the low-altitude communication grid as a reference and follows a priority direction (i.e., the communication interaction vector). For example, if the UAV needs to maintain continuous communication with the control center, the communication planning unit will select the appropriate frequency band and link according to the real-time feedback of the UAV control signal, image transmission signal and positioning signal. For example, a UAV performs a monitoring mission near an airport. There are many potential interference sources in the area (such as other wireless devices). If the UAV encounters signal interference while performing the mission, the system will dynamically adjust the communication link, select a stable frequency band and plan a new communication corridor. For example, it may switch from 2.4GHz to 5.8GHz band to ensure the normal image transmission and flight control.

[0021] The anchor point identification unit M400 is used to parse the UAV control signal subset, image transmission signal subset, and positioning signal subset, identify frequency characteristic indicators, and anchor point identify the low-altitude communication corridor to obtain a frequency hopping positioning switching sequence; the interference simulation unit M500 is used to introduce a transmission interference instance in the communication environment within the low-altitude communication corridor to perform interference simulation evaluation, wherein the transmission interference instance has any one or more of a signal interference scene mark, an electromagnetic interference scene mark, an optoelectronic interference scene mark, and a camouflage interference scene mark; the communication protection unit M600 is used to simultaneously, for the initial frequency band intervals of the multiple communication links, use the frequency hopping positioning switching sequence and the spread spectrum positioning switching sequence to perform multi-band interference control adjustment, determine the interference control strategy, and perform communication protection during the interaction between the target UAV and the terminal control center.

[0022] Specifically, anchor point identification refers to identifying key communication nodes or frequency characteristic indicators in the low-altitude communication corridor and marking them as anchor points. These anchor points are similar to important reference points in the navigation system and are used to guide the frequency hopping and switching of the communication link; the frequency hopping positioning switching sequence refers to the preset switching sequence in which the device maintains stable communication by constantly changing the communication frequency in a multi-band environment to avoid interference. This is an adaptive frequency hopping mechanism for flexible switching between multiple frequency bands; interference scenario marking refers to the marking and classification of different types of interference scenarios during the interference simulation process. For example, signal interference markers, electromagnetic interference markers, optoelectronic interference markers and camouflage interference markers represent different types of interference sources.

[0023] Execution steps: First, the drone control signal, image transmission signal and positioning signal need to be analyzed in detail. These signals are classified into signal subsets, corresponding to the drone's operation control, image data transmission and GPS positioning respectively. The system detects the frequency characteristics of each signal subset and identifies its key frequency indicators. These key frequency indicators are the anchor points that the system needs to mark in the low-altitude communication corridor. For example, when the drone transmits images in the 2.4GHz frequency band, the system identifies the best transmission path in the 2.4GHz frequency band as the anchor point to ensure signal stability during image transmission. Once these anchor points are determined, the system will generate a frequency hopping positioning switching sequence to prepare for subsequent interference response.

[0024] Interference signals are artificially introduced into the communication environment to evaluate the system's ability to cope with different interference sources. These interferences may include signal interference, electromagnetic interference, optoelectronic interference, and camouflage interference. Various possible interference scenarios are simulated to evaluate the anti-interference capability of the drone communication system. The interference simulation unit will inject multiple types of interference signals into the low-altitude communication corridor, which are marked as signal interference scene markers, electromagnetic interference scene markers, optoelectronic interference scene markers, and camouflage interference scene markers. For example, when a drone flies over a city, electromagnetic interference may come from surrounding radio stations. This electromagnetic interference scenario is simulated and tested by inserting noise signals.

[0025] After the interference simulation is completed, communication protection is performed according to the detected interference intensity and type. Here, the system will enable the preset frequency hopping positioning switching sequence and spread spectrum positioning switching sequence, and perform frequency hopping and spread spectrum between different frequency bands according to the interference environment. Frequency hopping technology avoids interference sources by constantly changing the communication frequency band, while spread spectrum technology disperses the signal to transmit it on a wide frequency band. For example, when the drone encounters signal interference while performing a mission, the frequency hopping mechanism will automatically switch the communication link from the interfered frequency band to a cleaner frequency band, such as from 2.4GHz to 5.8GHz, to ensure that the communication between the drone and the control center is not interrupted. At the same time, the spread spectrum positioning switching sequence transmits data on the entire frequency band by increasing the spectrum width of the signal, which can effectively disperse the impact of the interference source. Finally, according to the execution results of frequency hopping and spread spectrum, the interference situation in the current communication environment is comprehensively evaluated, and an interference control strategy is generated. The interference control strategy will predict potential interference sources and affected areas in advance based on previous interference simulation results. By coordinating the frequency-hopping positioning switching sequence with the spread spectrum positioning switching sequence, the interference frequency band and signal transmission path are flexibly adjusted to successfully shield or interfere with the control signal, image transmission signal and positioning signal of the drone, achieving the technical effect of forcing the drone remote control to be interrupted, image transmission to fail, and positioning function to be disordered, thereby effectively preventing the drone from operating normally and ensuring the safety and privacy protection of the target area.

[0026] Furthermore, each communication link is configured within the initial frequency band interval, and the communication grid establishment unit M100 is used to perform the following method:

[0027] According to the frequency band monitoring task issued by the terminal control center and in combination with the flight environment conditions of the target UAV, a frequency band allocation target is set, and the frequency band allocation target includes a transmission rate allocation threshold and a communication efficiency allocation threshold; based on the low-altitude communication grid and in combination with the transmission rate allocation threshold in the frequency band allocation target, a first frequency band connection layer is established; based on the low-altitude communication grid and in combination with the communication efficiency allocation threshold in the frequency band allocation target, a second frequency band connection layer is established; based on the first frequency band connection layer and the second frequency band connection layer, a frequency band allocation mechanism is set.

[0028] Specifically, the communication link refers to the communication path between the UAV and the control center, which transmits data through radio frequencies. Each communication link sends and receives data based on a preset frequency band; the frequency band allocation target is an optimization strategy for the frequency band resources required for the communication link, including the transmission rate allocation threshold and the communication efficiency allocation threshold. The former is used to set the minimum rate requirement for data transmission in the communication link, and the latter is used to ensure the transmission efficiency of the entire communication system; the low-altitude communication grid is a network composed of multiple communication links between the UAV and the terminal control center, mainly covering the low-altitude airspace communication frequency bands used by the UAV during flight; the frequency band connection layer is a hierarchical structure of communication links in different frequency bands. The first frequency band connection layer corresponds to the optimization of the transmission rate, while the second frequency band connection layer is optimized for communication efficiency; the frequency band allocation mechanism is based on two frequency band connection layers, and the system automatically allocates the best frequency band to ensure the reliability and efficiency of communication, including selecting the best frequency band from multiple available frequency bands to allocate to each communication link.

[0029] Execution steps: The terminal control center will issue a frequency band monitoring task based on the specific mission of the drone. This task needs to set the frequency band allocation target of the communication link in combination with the flight environment conditions of the drone; Transmission rate allocation threshold setting: If the drone mission requires real-time transmission of high-definition video images (such as reconnaissance or monitoring tasks), the transmission rate allocation threshold will be higher to ensure smooth transmission of video data and avoid delays and freezes; Communication efficiency allocation threshold setting. Furthermore, if the drone flies in an environment with complex interference, the communication efficiency allocation threshold needs to be adjusted according to the interference situation of the channel to ensure that the drone's control signals and data are efficiently transmitted in the network without being affected by interference.

[0030] After the frequency band allocation target is set, the system needs to establish the first frequency band connection layer, which is for the optimization of transmission rate. The system will combine the flight conditions of the drone and the communication link between it and the control center to determine which frequency bands can provide the best transmission rate; by analyzing multiple communication links in the low-altitude communication grid, select frequency bands within the transmission rate allocation threshold range. These frequency bands will give priority to ensuring the speed of data transmission, especially in cases of high data demand (such as real-time video transmission). For example: System analysis shows that the 2.4GHz frequency band has a good transmission rate and is suitable for the transmission of high-definition video, so this frequency band is allocated to the first frequency band connection layer.

[0031] On the basis of ensuring the transmission rate, it is also necessary to optimize the communication efficiency. At this time, the second frequency band connection layer will be established; according to the communication efficiency allocation threshold, select those frequency bands that can ensure signal stability, low interference and efficient transmission of control instructions. This connection layer mainly ensures the robustness of the communication link, especially in scenarios that require long-term missions or communications in complex environments; based on these two frequency band connection layers, by analyzing the real-time communication needs and environmental interference of the drone, a dynamic frequency band allocation mechanism is established. This mechanism balances the transmission rate and communication efficiency, and alternately or in parallel allocates the frequency bands of the first and second frequency band connection layers to ensure that the communication between the drone and the terminal control center is always in the best state. Through the above steps, the frequency band allocation mechanism that the drone can use in different mission environments and communication needs is restored to provide support for setting targeted interference countermeasures.

[0032] Further, based on the first frequency band connection layer and the second frequency band connection layer, a frequency band allocation mechanism is set, and the communication grid establishment unit M100 is further used to perform the following method:

[0033] The first frequency band connection layer is used as the upper layer, and the second frequency band connection layer is used as the lower layer to connect nodes to construct a frequency band optimized fully connected layer; the target UAV is connected to obtain real-time operating parameters, and the real-time operating parameters include flight speed, flight altitude, and flight direction; based on the frequency band optimized fully connected layer, the frequency band configuration of multiple communication links in the low-altitude communication grid is dynamically adjusted through the real-time operating parameters to obtain the frequency band allocation mechanism.

[0034] Specifically, the frequency band optimized fully connected layer is a multi-layer network structure consisting of the first frequency band connection layer and the second frequency band connection layer, which aims to provide dynamic and optimal frequency band allocation for UAV communications. The upper layer (the first frequency band connection layer) is responsible for optimizing the transmission rate, while the lower layer (the second frequency band connection layer) focuses on ensuring communication efficiency. The real-time operation parameters are the real-time data obtained by the UAV during the flight, mainly including its flight speed, flight altitude and flight direction. These parameters directly affect the communication needs and frequency band selection of the UAV.

[0035] Execution steps: The first band connection layer and the second band connection layer need to be connected as nodes to form a band-optimized fully connected layer. This process is implemented through programming. The band characteristics in each band connection layer are defined and connected as nodes. During the connection process, the system will compare the band characteristics of each layer, such as transmission rate and communication efficiency, to ensure a quick response when switching bands. For example, assuming that the first band connection layer includes band A (2.4GHz) and band B (5.8GHz), and the second band connection layer includes band C (1.2GHz) and band D (900MHz), the system will establish a connection based on the transmission rate and communication efficiency to form a complete band-optimized fully connected layer.

[0036] The UAV is connected to the band-optimized fully connected layer through a wireless communication interface to obtain the operating parameters of the UAV in real time. The UAV collects parameters such as flight speed, flight altitude and flight direction through built-in sensors and sends these parameters to the control center through a data link. For example, when the UAV flies over a city at a speed of 10 m / s, an altitude of 100 m and a direction of northwest (such as NW 45°), these parameters can be updated in real time. Based on the real-time operating parameters obtained, the system will dynamically adjust through the band-optimized fully connected layer to optimize the frequency band configuration of multiple communication links in the low-altitude communication grid, and determine the most suitable frequency band according to the flight speed and altitude of the UAV. For example, when the UAV is flying at a higher speed, the system may give priority to a frequency band that can provide a high transmission rate (such as 2.4 GHz) to ensure fast data transmission and real-time response of control signals. On the other hand, if the UAV is crossing complex terrain (such as a valley or an area with many buildings), the system will adjust the frequency band to a less interfered frequency band (such as 900 MHz) to ensure signal stability. This dynamic adjustment mechanism can ensure that the UAV always maintains the best communication quality in various environments. Through the above steps, the entire frequency band allocation mechanism realizes efficient and stable communication between the drone and the control center during flight, providing support for setting up targeted interference countermeasures.

[0037] Further, based on the low-altitude communication grid and in combination with the transmission rate allocation threshold in the frequency band allocation target, a first frequency band connection layer is established, and the communication grid establishment unit M100 is further used to execute the following method:

[0038] Connect the RF power amplifier module, obtain the operating parameters of the first device, and determine the basic value of the transmission rate; compare the basic value of the transmission rate with the transmission rate allocation threshold in the frequency band allocation target, and screen according to the comparison result to form a first candidate frequency band set; select the optimal frequency band combination from the first candidate frequency band set, and determine the inter-layer mapping map of the first frequency band connection layer.

[0039] Specifically, the first frequency band connection layer is a communication layer built on the basis of the low-altitude communication grid, which is mainly used to optimize the transmission rate to meet the communication needs of the drone; the RF power amplifier module is a device used to amplify the signal strength to ensure that the signal does not lose quality due to attenuation during transmission. It can increase the power of the transmitted signal to ensure a wider signal coverage range; the basic transmission rate value refers to the transmission rate that the drone can currently achieve under a specific environment and equipment configuration. This value is determined by multiple factors, including environmental conditions, equipment performance, etc.; the frequency band allocation target is a target parameter set to optimize communication performance, including the transmission rate allocation threshold, etc., which is used to guide the selection and adjustment of frequency bands; the first candidate frequency band set refers to the list of available frequency bands screened out by comparing the transmission rate basic value with the transmission rate allocation threshold to ensure that these frequency bands can meet the set communication needs; the inter-layer mapping map is a data structure used to describe how the frequency band connection layers are connected and interacted with each other, indicating the usage and optimization strategies of different frequency bands.

[0040] Execution steps: construct the first frequency band connection layer based on the low-altitude communication grid and the transmission rate allocation threshold in the frequency band allocation target. This process includes connecting to the RF power amplifier module, obtaining the first device operating parameters from it and determining the basic value of the transmission rate; comparing the obtained basic value of the transmission rate with the transmission rate allocation threshold in the set frequency band allocation target. According to the comparison result, the system will screen out qualified frequency bands to form a first candidate frequency band set. For example, assuming that the candidate set includes frequency band A (2.4 GHz), frequency band B (5.8 GHz), etc.; from the first candidate frequency band set, the system will select the optimal frequency band combination to determine the inter-layer mapping spectrum of the first frequency band connection layer. This selection process may involve evaluating other indicators of the candidate frequency bands, such as signal quality, interference conditions and usage scenarios. For example, if the bit error rate of frequency band A is low and the transmission delay of frequency band B is high, the system will give priority to frequency band A to ensure the stability of communication. Finally, after evaluation, the mapping spectrum that may be formed is as follows: Frequency band A (2.4 GHz): used for real-time image transmission; Frequency band B (5.8 GHz): used to control signal transmission; the system will record this mapping information and establish a suitable frequency band connection layer for the drone's communication needs, thereby providing guidance for subsequent communication interference control.

[0041] Further, an optimal frequency band combination is selected from the first candidate frequency band set, and an inter-layer mapping spectrum of the first frequency band connection layer is determined. The communication grid establishment unit M100 is further used to perform the following method:

[0042] Based on multiple communication links in the low-altitude communication grid, communication quality indicators are extracted, and the communication quality indicators include bit error rate and transmission delay; with the communication quality indicators as constraints, the optimal frequency band combination is selected from the first candidate frequency band set.

[0043] Specifically, the first candidate frequency band set refers to multiple available frequency bands obtained through comparison under the transmission rate allocation threshold. These frequency bands have been preliminarily screened and have potential good communication performance; communication quality indicators are quantitative indicators used to evaluate the performance of communication links, including: bit error rate (BER) refers to the ratio of the number of erroneous bits to the total number of bits per unit time, usually expressed as a percentage, reflecting the clarity and stability of the signal; transmission delay refers to the time required for a signal to be transmitted from the transmitter to the receiver, affecting real-time performance and response speed; the inter-layer mapping map is used to describe the structure of how different frequency bands interact in the connection layer, and provides a graphical representation of the relationship between communication links to help determine the optimal transmission path for data.

[0044] Execution steps: Before determining the frequency band combination of the first frequency band connection layer, the system first needs to evaluate multiple communication links in the low-altitude communication grid. By analyzing these links, the system extracts corresponding communication quality indicators to evaluate the performance of each candidate frequency band, and uses monitoring tools (such as spectrum analyzers) to collect bit error rate and transmission delay data in real time. Once the communication quality indicators are obtained, the system will use these data as constraints to select the optimal frequency band combination from the first candidate frequency band set. Assume that in the candidate set, the bit error rate and delay of band A and band B are as follows: Band A: bit error rate 0.1%, transmission delay 20ms; Band B: bit error rate 0.5%, transmission delay 30ms; Band C: bit error rate 0.05%, transmission delay 15ms; In this case, band C will be selected first because it has the lowest bit error rate and the shortest transmission delay. The selection conditions may include: the bit error rate should be less than 0.1%, and the transmission delay should be less than 25ms.

[0045] After selecting the optimal frequency band combination, the system will create an inter-layer mapping map based on these frequency bands to guide future communication operations. Furthermore, if band C is selected as the main frequency band for data transmission, the system can connect this band with other frequency bands (such as band A for control signals) to form the following mapping map: band C (main frequency band, used for data transmission); band A (control signal frequency band). The system records this information to provide a basis for subsequent dynamic adjustments. For example, in future missions, if the quality indicators of band C deteriorate, quickly switch to band A or other available frequency bands. Through the above steps, the system can effectively screen and determine the optimal frequency band combination for drone communications, ensure comprehensive monitoring of all available frequency bands, and provide support for comprehensive interference control.

[0046] Further, based on the low-altitude communication grid and in combination with the communication efficiency allocation threshold in the frequency band allocation target, a second frequency band connection layer is established, and the communication grid establishment unit M100 is further used to execute the following method:

[0047] Connect to the routing and switching module, obtain the operating parameters of the second device, and determine the basic value of communication efficiency; compare the basic value of communication efficiency with the communication efficiency allocation threshold in the frequency band allocation target, and screen according to the comparison result to form a second candidate frequency band set; based on the second candidate frequency band set, determine the inter-layer mapping map of the second frequency band connection layer.

[0048] Specifically, the second frequency band connection layer refers to the second-layer communication frequency band established in the low-altitude communication grid, which aims to improve communication efficiency and ensure the stability of information transmission; the routing and switching module is responsible for transmitting data between different network devices and optimizing data paths, thereby improving communication efficiency; the communication efficiency basic value represents the data transmission efficiency of a specific frequency band under actual operating conditions, usually expressed in bits per second (bps); the communication efficiency allocation threshold defines the minimum acceptable communication efficiency standard under certain conditions. If the communication efficiency basic value is lower than the threshold, the frequency band will no longer be selected; the second candidate frequency band set is a set of available frequency bands obtained after screening based on the communication efficiency basic value and the allocation threshold; the inter-layer mapping map is a structural diagram used to describe the relationship between different frequency bands in the second frequency band connection layer, showing how the frequency bands work together.

[0049] Execution steps: Before establishing the second frequency band connection layer, the system first needs to connect to the routing and switching module. The task of this module is to monitor and collect equipment operating parameters related to the frequency band to determine the basic value of communication efficiency. For example, the system may track the speed of data transmission, packet loss rate, delay and other information in real time through the routing and switching module. In one monitoring, the system found that the transmission speed of frequency band G is 5 Mbps and the transmission speed of frequency band H is 3 Mbps. At this time, the basic value of communication efficiency of frequency band G is 5 Mbps.

[0050] Once the basic value of communication efficiency is obtained, the system will compare it with the communication efficiency allocation threshold defined in the frequency band allocation target. This threshold may be set by the terminal control center according to the task requirements. For example, the allocation threshold is 4 Mbps. The system will compare frequency band G (5 Mbps) with frequency band H (3 Mbps). Since frequency band G is higher than the threshold and frequency band H is lower than the threshold, the system will exclude frequency band H to form a second candidate frequency band set, and only frequency band G is retained at this time; based on the screened second candidate frequency band set, the system will build an inter-layer mapping map for the second frequency band connection layer to optimize the communication path and configuration. For example, frequency band G, as the only candidate frequency band, will be designated as the main data transmission frequency band. At this time, the system records its relationship with other frequency bands (such as frequency band I, used for backup control signals) and establishes a corresponding mapping map, such as: frequency band G (main frequency band); frequency band I (backup frequency band); through this mapping, the drone can quickly switch frequency bands to cope with future environmental changes and communication needs. Through the above steps, the system can efficiently establish and adjust the second frequency band connection layer, focus on monitoring the main frequency band, and provide support for targeted interference control.

[0051] Further, for the initial frequency band intervals of the multiple communication links, the frequency hopping positioning switching sequence and the spread spectrum positioning switching sequence are used to perform interference control adjustment of multiple frequency bands to determine the interference control strategy, and the communication protection unit M600 is used to execute the following method:

[0052] Based on transmission interference examples, an interference scenario model library is established; according to potential interference sources in the communication environment in the low-altitude communication corridor, multiple matching interference scenario models are selected from the interference scenario model library; the multiple matching interference scenario models and the initial frequency band intervals of the multiple communication links are used to deploy in the low-altitude communication corridor to evaluate the degree of interference; according to the interference degree evaluation results of the initial frequency band intervals of the multiple communication links, the frequency hopping positioning switching sequence and the frequency hopping switching instruction, the spread spectrum positioning switching sequence and the spread spectrum switching instruction, the multi-band interference control adjustment is performed.

[0053] Specifically, the frequency hopping positioning switching sequence is a signal sequence that quickly switches between different frequency bands, which is used to enhance the anti-interference ability and concealment of communications; the spread spectrum positioning switching sequence is a signal sequence that transmits by spreading the signal to a wider frequency band, aiming to improve the signal's anti-interference and multipath propagation capabilities; transmission interference examples: interference situations in specific circumstances, such as signal attenuation, noise interference or electromagnetic interference; the interference scenario model library contains a database of various interference scenarios and provides models of different interference situations for predicting and evaluating the impact of interference on communication links; the matching interference scenario model is a model selected from the interference scenario model library based on the characteristics of the specific communication environment and that matches the actual environment.

[0054] Execution steps: Establish an interference scenario model library based on different types of transmission interference instances. This library will store a variety of possible interference scenario models, including electromagnetic interference, signal loss, noise impact, etc. For example, the system may record the interference conditions and performance of different signal types (such as Wi-Fi, Bluetooth) in specific environments (such as cities, mountainous areas, etc.). These data are obtained through previous experiments and tests to provide a reference for subsequent interference control strategies.

[0055] According to the communication environment in the low-altitude communication corridor, the system will select multiple scenario models that match potential interference sources from the interference scenario model library. Suppose in a certain mission, the system detects electromagnetic interference near a building. Based on the data in the model library, the system can select the interference model corresponding to the building environment for analysis; using the selected matching interference scenario model, the system deploys interference in the low-altitude communication corridor to evaluate the performance of multiple communication links under different interference conditions. For example, the system introduces multiple communication links in a simulated environment and tests their transmission effects under specific interference sources (such as signal shielding, strong interference noise) according to the model, and records the signal quality of each link (such as bit error rate, delay, etc.).

[0056] According to the interference level evaluated in the previous steps, the system will analyze the performance of the initial frequency band intervals of multiple communication links and adjust the interference control strategy accordingly. If a certain communication link performs poorly under specific interference conditions, the system may start the frequency hopping positioning switching sequence to quickly switch to a frequency band with less interference, or apply the spread spectrum positioning switching sequence to improve the signal's anti-interference ability. In this process, the system will send frequency hopping and spread spectrum instructions to the RF power amplifier module and the routing switch module to dynamically adjust the frequency of the signal to ensure the reliability of communication. For example, if frequency band A is subject to strong interference, the system can adjust to frequency band B or C. Through the above steps, the system can effectively manage and optimize the interference control strategy of the communication link.

[0057] Furthermore, the communication protection unit M600 is also used to perform the following method:

[0058] The frequency hopping switching instruction is issued by the RF power amplifier module, corresponding to the inter-layer mapping map of the first frequency band connection layer; the spread spectrum switching instruction is issued by the routing switching module, corresponding to the inter-layer mapping map of the second frequency band connection layer.

[0059] Specifically, the frequency hopping switching instruction is used to instruct the communication system to switch between different frequency bands to avoid or reduce interference; the radio frequency power amplifier module, that is, the radio frequency (RF) power amplifier, is used to enhance the strength of the wireless signal to ensure that the signal can cover a larger area or resist interference; the spread spectrum switching instruction is used to instruct the communication system to use spread spectrum technology for signal transmission to enhance the signal's anti-interference ability and transmission quality; the routing switching module is responsible for the equipment or components of data packet forwarding and route selection, and can dynamically adjust the data transmission path according to network conditions; the first frequency band connection layer refers to the connection layer associated with a specific frequency band in the low-altitude communication grid, which is responsible for processing signals and instructions related to the frequency band; the second frequency band connection layer refers to the connection layer associated with another specific frequency band in the low-altitude communication grid, which is responsible for processing signals and instructions related to the frequency band; the inter-layer mapping map is a diagram or data structure used to describe the mapping relationship and interaction logic between different connection layers.

[0060] Execution steps: When the system detects that the signal quality of a communication link has decreased or faces a potential interference source, the RF power amplifier module will generate and issue a frequency hopping switching instruction. This instruction is to instruct the system to quickly switch to other frequency bands; the frequency hopping switching instruction corresponds to the inter-layer mapping map of the first frequency band connection layer. This mapping map describes the relationship between the connection layers under different frequency bands and can connect to the corresponding frequency band when performing frequency hopping; in some cases, the signal may be affected by the transmission distance or environmental noise. At this time, the routing and switching module will generate and issue a spread spectrum switching instruction, so that the system uses spread spectrum technology to enhance the stability and anti-interference ability of the signal; the spread spectrum switching instruction corresponds to the inter-layer mapping map of the second frequency band connection layer, so that the system can quickly find a suitable connection layer and transmit signals when performing spread spectrum; in the process of executing frequency hopping and spread spectrum, the system continuously monitors the signal quality and environmental changes, effectively manages the signal transmission of multiple frequency bands, and the dynamic issuance of frequency hopping switching instructions and spread spectrum switching instructions and the mapping relationship between the connection layers, and the corresponding interference control strategy is formulated to counter, thereby effectively shielding the control signal, image transmission signal and positioning signal of the drone, forcing the drone remote control, image positioning, and signal interruption.

[0061] In summary, the beneficial effects of the embodiments of the present application are:

[0062] 1. By establishing a low-altitude communication grid and multi-band communication links, comprehensive coverage of multi-band communications for drones is achieved. Through real-time spectrum scanning and frequency hopping and spread spectrum positioning switching sequences, the interference frequency band can be flexibly adjusted, thereby effectively shielding the drone's control signal, image transmission signal and positioning signal, forcing the drone's remote control, image positioning, and signal interruption.

[0063] 2. Dynamically adjust the interference strategy based on the real-time operating parameters such as the UAV flight environment and the quality of the communication link, and avoid interference with normal communications through communication planning and frequency band allocation of low-altitude communication corridors.

[0064] 3. Through interference simulation and scene marking evaluation, potential interference sources and sensitive areas can be identified in advance, and according to the interference level and frequency hopping switching instructions, the interference strategy can be optimized to improve the accuracy and effect of drone interference.

[0065] 4. Since the frequency hopping switching instruction is issued by the RF power amplifier module, it corresponds to the inter-layer mapping spectrum of the first frequency band connection layer; the spread spectrum switching instruction is issued by the routing switching module, which corresponds to the inter-layer mapping spectrum of the second frequency band connection layer. In the process of executing frequency hopping and spread spectrum, the system continuously monitors the signal quality and environmental changes, effectively manages the signal transmission of multiple frequency bands, and the mapping relationship between the dynamic issuance of frequency hopping switching instructions and spread spectrum switching instructions and the connection layer, and the corresponding interference control strategy is formulated to counter it, thereby effectively shielding the control signal, image transmission signal and positioning signal of the drone, forcing the drone remote control, image positioning, and signal interruption.
