[0001] The present invention relates to the technical field of communication network management, and in particular to a low-altitude communication navigation integrated management system and method. Background Art

[0002] With the advancement of the low-altitude airspace opening policy, the demand for low-altitude flight is increasing, which puts higher requirements on low-altitude communication and navigation systems. Traditional communication and navigation systems cannot effectively meet the real-time communication, navigation and management needs in complex low-altitude environments.

[0003] In the prior art, some low-altitude communication and navigation systems use a single communication network or navigation equipment for regional management, such as using fixed base stations or beacons to achieve communication and navigation support for low-altitude aircraft. However, such solutions often lack flexibility when faced with the complex and diverse environmental characteristics of low-altitude flight areas, and are difficult to adapt to dynamically changing communication needs.

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1: The embodiment of the present invention provides a low-altitude communication navigation integrated management system, such as Figure 1 As shown, including: Demand analysis module: obtains the communication and navigation requirements of the preset low-altitude flight area and conducts demand analysis; Network division module: Determine several communication network modules of the preset low-altitude flight area based on the demand analysis results and the scene characteristics of the preset low-altitude flight area; Configuration and deployment module: Based on the divided communication network modules, deployment is performed using a preset configuration method; Data acquisition module: a preset sensor network is deployed inside each communication network module to monitor and collect the surrounding environment data of each communication network module and the device status data of each communication network module; Communication management module: Analyze the collected surrounding environment data of each communication network module and the equipment status data of each communication network module, and then determine the low-altitude communication navigation management strategy based on the analysis results.

[0025] In this embodiment, the preset low-altitude flight area refers to the airspace range geographically demarcated for the purpose of communication and navigation of low-altitude aircraft (such as drones and helicopters). These areas are usually specific low-altitude flight scenarios, such as urban logistics routes, agricultural operation areas, or disaster relief areas. For example: the airspace below 300 meters in the city is demarcated as a low-altitude flight area for drone logistics distribution, and satellite communications are used to cover the area to ensure stable communication and navigation between the aircraft and the ground station; In this embodiment, the communication and navigation requirements refer to the functional requirements for communication and navigation put forward by low-altitude aircraft during flight to ensure safe and efficient operation, such as real-time positioning, route adjustment, communication with ground stations, etc. For example, a drone needs to receive accurate navigation signals and weather information through satellite communication, and send real-time flight data to adjust the route to avoid collision with other aircraft; In this embodiment, demand analysis is to determine the specific needs of communication and navigation, including signal coverage, communication bandwidth, navigation accuracy, etc., through a comprehensive analysis of the aircraft type, flight mission and environmental conditions in the low-altitude flight area. For example, by analyzing the low-altitude flight needs in mountain rescue areas, it is found that high-precision navigation signals and strong anti-interference communication capabilities are required, and it is recommended to adopt a communication solution that combines high-orbit satellites with ground relays.

[0026] In this embodiment, the communication network module refers to an independent communication network unit divided for low-altitude flight areas. Each module can be configured with specific communication and navigation functions according to flight requirements and regional characteristics. For example, in a low-altitude flight area, cities, rural areas and mountainous areas are divided into independent communication network modules. High-capacity satellite communication modules are used in urban areas, and low-latency modules are used in rural and mountainous areas to enhance navigation performance.

[0027] In this embodiment, the preset configuration method refers to a method for designing and deploying a satellite communication network based on demand, including selecting a satellite orbit (such as a low-orbit, medium-orbit or high-orbit satellite), setting a communication frequency band (such as a Ka band or a Ku band), and deploying ground terminals. For example: configuring a satellite communication network for a low-altitude logistics drone, selecting a low-orbit satellite to achieve low-latency communication, and cooperating with ground base stations to provide signal enhancement to ensure high reliability of navigation signals in urban areas.

[0028] In this embodiment, the preset sensor network refers to a sensor system arranged in the communication network module, which is a network used to monitor the surrounding environment (such as weather, signal strength) and equipment operating status (such as power consumption, temperature). For example: in a low-altitude flight area, the sensor network can collect real-time wind speed in the drone route and signal strength of the satellite communication terminal to ensure stable operation of communication and navigation.

[0029] In this embodiment, the device status data of the communication network module refers to the real-time data of the operation of the equipment in the communication network module, including the status of the communication equipment (such as signal power, data rate) and the operation status of the sensor equipment (such as battery power, transmission delay). For example: the device status data of a communication module shows that the signal power of the satellite communication terminal has decreased and the temperature of the sensor feedback device has increased, indicating that there may be a risk of hardware failure.

[0030] In this embodiment, the low-altitude communication and navigation management strategy refers to the management methods and solutions proposed for optimizing low-altitude aircraft communication and navigation based on communication and environmental data analysis, such as dynamic channel allocation and route optimization. For example, in severe weather conditions, the analysis results of satellite communications show that the navigation signal is interfered. The management strategy dynamically switches the channel frequency and replans the drone route to avoid strong interference areas to ensure flight safety.

[0031] The beneficial effects of the above technical solution are: through demand analysis, network division, dynamic configuration and data collection, accurate division and efficient deployment of communication networks in low-altitude flight areas are achieved, and real-time monitoring of the environment and equipment status by sensor networks is combined to improve the system's perception capabilities; based on analysis and optimization of collected data, dynamic communication and navigation management strategies are formulated to improve the system's flexibility, adaptability and reliability, and to achieve accurate demand matching, flexible network division, dynamic configuration optimization, and real-time data monitoring and management of low-altitude communication and navigation systems.

[0032] Embodiment 2: An embodiment of the present invention provides a low-altitude communication and navigation integrated management system, with preset configuration methods including: frequency band allocation method, topology structure configuration method, equipment deployment method, communication protocol configuration method, sensor network configuration method, energy supply configuration method, redundant backup configuration method and dynamic adjustment configuration method.

[0033] In this embodiment, the frequency band allocation method is to select a suitable satellite communication frequency band (such as L band, Ka band or Ku band) according to the low-altitude communication requirements to meet the signal transmission requirements in different scenarios, such as high coverage or high-bandwidth transmission. For example, when the drone logistics network flies at low altitude, the L band is allocated for navigation signals (because of its strong anti-interference ability) and the Ka band is allocated for large data transmission (such as real-time video streaming); In this embodiment, the topology configuration method is to design a connection mode between the satellite and the low-altitude communication network, including a star structure, a grid structure or a hybrid topology, to optimize communication efficiency and coverage. For example, in a disaster relief scenario, a grid topology is selected to connect low-orbit satellites, relay stations and aircraft to ensure multi-path redundant communication and avoid signal interruption. In this embodiment, the equipment deployment method is to reasonably arrange communication and navigation equipment, such as satellite terminals, base stations and relay stations, in the low-altitude flight area to ensure that the signal coverage has no dead angles. For example, in a mountainous flight area, a satellite communication receiver is deployed at a higher point of the terrain, and a ground relay station is deployed at the same time to improve the signal transmission efficiency; In this embodiment, the communication protocol configuration method is to select or customize a communication protocol suitable for low-altitude flight (such as TCP / IP, UDP or adaptive protocol) to improve data transmission efficiency and anti-interference performance. For example: using an adaptive communication protocol, when the drone communicates with a satellite, the data transmission rate and encoding method are automatically adjusted to ensure stable video and navigation data transmission; In this embodiment, the sensor network configuration method is to arrange the sensor network in the communication network module to collect environmental data (such as meteorological data) and equipment status data (such as satellite signal strength). For example, temperature and humidity sensors and wind speed sensors are arranged to collect low-altitude flight environment data and adjust the navigation path of the aircraft in combination with the satellite communication system; In this embodiment, the energy supply configuration mode is to design an energy supply scheme according to the equipment requirements, such as solar power supply, battery power supply or hybrid energy supply mode, to ensure the long-term stable operation of the communication system. For example: in remote mountainous flight areas, solar power supply is used to provide energy for satellite communication terminals and sensor networks to ensure the continuity of system operation; In this embodiment, the redundant backup configuration method is to design a redundant mechanism for key equipment and data to ensure that the communication system can still operate normally in the event of a failure. For example, a dual-link redundant backup mechanism is designed for a satellite communication terminal. When the main link fails, it automatically switches to the backup link to ensure that the UAV communication is not interrupted; In this embodiment, the dynamic adjustment configuration method is to monitor the communication environment and equipment status in real time, dynamically adjust the communication frequency band, topology structure or equipment parameters, to ensure that the system adapts to the changing low-altitude flight needs. For example, in a high-density flight area, when a frequency band is congested, the satellite communication system dynamically switches to a backup frequency band and adjusts the antenna direction to optimize signal coverage.

[0034] The beneficial effect of the above technical solution is: by introducing multi-dimensional configuration methods such as frequency band allocation, topology, equipment deployment, communication protocol, sensor network, energy supply, redundant backup and dynamic adjustment, efficient resource management, flexible adaptation and reliability improvement of the low-altitude communication and navigation system can be achieved.

[0035] Embodiment 3: The embodiment of the present invention provides a low-altitude communication and navigation integrated management system, a network division module, including: The first analysis unit: performs a first analysis on the scene characteristics of the preset low-altitude flight area to obtain a first feature of the preset low-altitude flight area, and at the same time, performs a second analysis on the scene characteristics of the preset low-altitude flight area to obtain a second feature of the preset low-altitude flight area; A first division unit: performing a first division on the preset low-altitude flight area based on a first feature of the preset low-altitude flight area and a preset division method; A second division unit: performing a second division on the preset low-altitude flight area after the first division based on a second feature of the preset low-altitude flight area and a preset division method; Area determination unit: determines the shape and coverage area of ​​each communication network module based on the demand analysis results and the preset low-altitude flight area scenario; The module determination unit determines a number of communication network areas based on the shape and coverage area of ​​each communication network module and the preset low-altitude flight area after the second division, and then determines a number of communication network modules.

[0036] The module determination unit determines a plurality of communication network areas based on the shape and coverage area of ​​each communication network module and the preset low-altitude flight area after the second division. In this embodiment, the first analysis is to analyze the overall characteristics of the preset low-altitude flight area from a macro perspective, extract basic attributes such as environment, terrain, flight density, etc., and provide a basis for preliminary division. For example: in the satellite communication scenario, the first analysis makes a preliminary assessment of the geographical characteristics (such as cities and mountainous areas) and flight demand density of a low-altitude flight area, and extracts the area as "flat and open land with high flight density"; In this embodiment, the second analysis is to further analyze the specific characteristics of the preset area from a detailed perspective, and to explore more local details, such as weather, distribution of communication interference sources, etc., for fine division. For example: based on satellite monitoring data, the second analysis found that some parts of the above-mentioned area have strong wireless interference (such as areas with dense communication towers) and complex weather (such as foggy areas), which require special treatment.

[0037] In this embodiment, the first division is based on the macro characteristics obtained by the first analysis, and the low-altitude flight area is preliminarily divided into blocks at a larger scale to form a coarse-grained division result. For example, based on the analysis results of satellite communications, the first division divides the entire low-altitude flight area into three main communication network modules: urban core area, rural low-density area and mountainous complex area.

[0038] In this embodiment, the second division is based on the first division, and according to the refined features of the second analysis, the preliminary blocked areas are further subdivided to form smaller and more precise communication network units. For example, for the core area of ​​the city, the second division further distinguishes between areas with high-rise buildings (strong signal obstruction) and open commercial areas (high signal demand), providing a detailed plan for satellite signal deployment.

[0039] In this embodiment, the shape and coverage area of ​​each communication network module are determined by analyzing the geographical distribution and demand density of the low-altitude flight area to facilitate effective communication deployment. For example, through satellite remote sensing analysis, a communication network module is determined to be a rectangle, covering the core area of ​​the city's CBD, with an area of ​​5 square kilometers, ensuring that all aircraft can receive satellite navigation and communication signals.

[0040] In this embodiment, the determination of several communication network areas based on the shape, coverage area and preset low-altitude flight area after the second division of each communication network module is a division result combining the shape and area, and the number of communication network modules and their distribution are finally determined according to flight requirements and environmental characteristics. The communication coverage and navigation optimization strategy within each module is also determined accordingly. For example, through satellite communication analysis and the second division, the module determination unit divides an urban area into 5 communication network areas, covering high-density residential areas, commercial areas and industrial areas respectively, and determines the use of satellite communication signals of different frequency bands to meet the needs of each area.

[0041] The beneficial effects of the above technical solution are: by dividing the low-altitude flight area into multiple levels, dynamically determining the shape and coverage of the communication network module in combination with scene characteristics and demand analysis, it achieves refined regional division, optimized resource allocation and precise communication network layout, and improves the adaptability and efficiency of the low-altitude communication navigation system.

[0042] Embodiment 4: The embodiment of the present invention provides a low-altitude communication navigation integrated management system, wherein the first analysis unit includes: The first characteristics include: geographical characteristics and geographical electromagnetic interference characteristics, and the second characteristics include: airspace characteristics and aircraft arrangement characteristics.

[0043] In this embodiment, the geographical features refer to the geographical environment features of the low-altitude flight area, including terrain (plains, mountains, hills, etc.), landforms (open areas or densely populated buildings), etc. These factors will affect the satellite signal propagation path and coverage effect. For example, in a mountainous flight area, geographical feature analysis finds that valleys and peaks will block satellite signals, so it is necessary to plan the collaborative deployment of satellites and ground relay stations to ensure smooth signal transmission; In this embodiment, the geographic electromagnetic interference feature refers to the impact on satellite communication signals caused by radio interference in the geographical environment (such as high-density communication base stations or industrial equipment in the city). For example, in the analysis of the core area of ​​the city, the geographic electromagnetic interference feature shows that there is a large amount of 5G base station signal interference, and satellite communication needs to select a frequency band with less interference (such as the L band) for low-altitude aircraft navigation; In this embodiment, airspace characteristics refer to the airspace distribution within the low-altitude flight area, including open airspace, no-fly airspace, and airspace hierarchical division, which directly affects the satellite communication coverage design and frequency allocation strategy. For example, in the airspace characteristics analysis, a certain area includes part of the military no-fly airspace, and it is necessary to ensure that the satellite signal avoids the airspace, while providing strong coverage for the adjacent open airspace to ensure the navigation continuity of low-altitude aircraft; In this embodiment, the aircraft arrangement characteristics refer to the distribution density, arrangement mode (such as column, scatter) and movement trajectory characteristics of low-altitude aircraft in a specific area. These characteristics affect the satellite communication capacity demand and coverage accuracy. For example, the analysis of aircraft arrangement characteristics shows that logistics drones present a high-density point-to-point mode in urban distribution. Therefore, it is necessary to strengthen the bandwidth allocation and latency optimization of satellite communications to support the simultaneous transmission of large amounts of data.

[0044] The beneficial effect of the above technical solution is: by comprehensively analyzing geographical features, electromagnetic interference features, airspace features and aircraft arrangement features, a multi-dimensional feature model of the low-altitude communication and navigation system is constructed, accurate evaluation and optimal configuration of complex low-altitude environments can be achieved, and the robustness and adaptability of communication and navigation can be significantly improved.

[0045] Embodiment 5: The embodiment of the present invention provides a low-altitude communication navigation integrated management system, an area determination unit, including: Demand analysis subunit: determines several demand data based on demand analysis results; Scenario analysis subunit: Analyze the scenario of the preset low-altitude flight area to determine the regional characteristics and environmental characteristics of each communication network module; Flight analysis subunit: obtains and analyzes relevant data of the aircraft to determine the flight characteristics of the aircraft for each communication network module; A coefficient determination subunit: determining a module form factor of each communication network module based on regional characteristics, environmental characteristics, and flight characteristics of the aircraft of each communication network module in combination with demand data; A shape determination subunit: determining a module shape of each communication network module based on a module shape coefficient of each communication network module and a preset coefficient-shape data table; Area determination subunit: determines the coverage area of ​​each communication network module based on all demand data, regional characteristics of each communication network module and environmental characteristics.

[0046] In this embodiment, regional characteristics refer to the attributes of a specific geographical area covered by satellite communications, including terrain (plains, mountains, oceans, etc.), landform complexity (open areas, canyons, etc.), and signal propagation conditions in the area (such as obstruction). For example, in a mountain flight scenario, regional characteristic analysis shows that there is signal obstruction in the mountains, and the communication network module needs to design multiple relay nodes to assist in signal coverage, while using low-orbit satellites to provide dynamically adjusted signal transmission paths. In this embodiment, environmental characteristics describe the external environmental conditions of the communication area, including meteorological conditions (wind speed, rainfall, ionospheric interference) and electromagnetic interference (interference from other communication equipment or regional wireless signals). For example, in a low-altitude flight scenario over the sea, environmental characteristics show that high humidity and heavy rain will weaken Ku-band signal transmission, so it is necessary to switch to the L-band to improve satellite communication stability.

[0047] In this embodiment, the flight characteristics of the aircraft include flight speed, altitude, trajectory mode (straight flight, cruising, circling) and density distribution. These characteristics directly affect the planning of bandwidth allocation, coverage and real-time requirements of the satellite communication network. For example, in the UAV formation operation scenario, the flight characteristics of the aircraft are high-density, low-speed circling. The satellite communication network needs to plan centralized beam coverage and give priority to allocating higher bandwidth to support real-time data transmission.

[0048] In this embodiment, the module form factor is a mathematical description of the shape of the communication network module, which is used to optimize the satellite signal coverage area and ensure the efficiency and coverage uniformity of the low-altitude communication network. It comprehensively considers regional characteristics, environmental characteristics, and aircraft flight characteristics to define the optimal module coverage shape. For example, in the urban distribution scenario, the regional characteristics show that the buildings are dense and the aircraft trajectories are asymmetrically distributed. The module form factor analysis shows that rectangular coverage is more suitable for this scenario than circular, thereby reducing signal blind spots and optimizing communication resource utilization.

[0049] The beneficial effects of the above technical solution are: through three-dimensional analysis of demand, scenario, and flight, combined with dynamic calculation of module shape coefficient and coverage area, the module shape and coverage range of the low-altitude communication network are accurately determined, and multi-demand-oriented communication resource optimization configuration is achieved, which improves the flexibility, adaptability and coverage efficiency of navigation management.

[0050] Embodiment 6: The embodiment of the present invention provides a low-altitude communication navigation integrated management system, the coefficient determination subunit includes: The module form factor of each communication network module is determined based on the regional characteristics, environmental characteristics and flight characteristics of the aircraft combined with the demand data:

[0054]

[0055] in, is the module shape factor of the i-th communication network module, is the regional characteristic coefficient of the i-th communication network module, is the influence coefficient of obstacles in the area where the i-th communication network module is located, is the preset maximum value of the obstacle influence coefficient, is the maximum flight altitude of the aircraft of the i-th communication network module, is the airspace height limit of the i-th communication network module, is the area of ​​the no-fly zone of the ith communication network module, is the flight area of ​​the ith communication network module, is the height characteristic influence coefficient, is the flight range characteristic influence coefficient, is the environmental impact coefficient of the i-th communication network module, is the severe weather impact coefficient of the i-th communication network module, is the attenuation coefficient of climate on signal propagation, is the influence coefficient of electromagnetic interference on signal strength, is the electromagnetic interference intensity of the i-th communication network module, is the flight characteristic coefficient of the aircraft of the i-th communication network module, is the average flight altitude coefficient of the aircraft in the i-th communication network module, is the average flight speed coefficient of the aircraft in the i-th communication network module, is the influence coefficient of aircraft altitude on communication coverage, is the influence coefficient of aircraft flight speed on communication coverage, is the demand characteristics influence coefficient, is the influence coefficient of the importance of the jth demand, is the influence coefficient of the feasibility of the jth demand, is the importance coefficient of the jth demand, is the feasibility coefficient of the jth demand, is the adjustment factor of the importance of the jth demand, is the adjustment factor for the feasibility of the jth demand, is the preset maximum importance coefficient, is the preset maximum feasibility coefficient, and ln is the logarithmic function.

[0056] In this embodiment, the attenuation coefficient of the climate on signal propagation describes the degree of weakening of the satellite signal strength due to climate conditions (such as rain, snow, fog, humidity, etc.). This coefficient is dynamically adjusted according to different climate conditions and determines the propagation efficiency of the signal in a specific climate environment. For example, in tropical areas, due to frequent rainstorms, the Ka-band signal in satellite communication is severely attenuated, and the attenuation coefficient of the climate on signal propagation is relatively large (for example, 0.8), and it is necessary to switch to a more stable L-band to ensure communication quality; In this embodiment, the obstacle influence coefficient indicates the degree of obstruction of satellite signal propagation by ground buildings, mountains or other obstacles. In areas with severe obstruction, the influence coefficient value is higher, and more supplementary measures are needed to maintain signal coverage. For example, in the central area of ​​the city, high-rise buildings are densely packed and irregularly distributed, resulting in an obstacle influence coefficient of 0.9. The solution is to reduce signal blind spots through joint coverage of low-orbit satellites and ground relay stations; In this embodiment, the regional characteristic coefficient combines factors such as geographical attributes, landforms, and airspace distribution to represent the impact of the region on the satellite communication network design. Complex areas (such as mountains or no-fly airspace) usually have higher regional characteristic coefficients. For example, in mountainous flight scenarios, due to significant terrain undulations and more airspace restrictions, the regional characteristic coefficient is 0.85, and it is necessary to increase the satellite beam partition design and cooperate with adaptive beam pointing technology to cover the gully area; In this embodiment, the demand feature impact coefficient reflects the weight of the user's communication demand on the network module design, combining the importance and feasibility of the demand. For example, high-priority, strong-demand scenarios will have a higher demand feature impact coefficient. For example, the real-time navigation demand of the logistics drone is marked as high priority, and the demand feature impact coefficient is 0.9. This means that the satellite communication network needs to prioritize the allocation of higher bandwidth resources for this scenario to ensure the accuracy of the aircraft path planning.

[0057] In this embodiment, the importance adjustment factor is used to adjust the importance coefficient of the demand to ensure that the core demand in a specific scenario is met first. Its value is dynamically determined by integrating user requirements and system resource configuration. For example, in a disaster emergency communication scenario, the real-time data transmission of search and rescue drones is considered extremely important. The importance coefficient of the demand is increased from 0.85 to 0.95 through the adjustment factor, thereby giving priority to the real-time transmission resources of the satellite communication network; In this embodiment, the feasibility adjustment factor is used to dynamically adjust the feasibility of realizing the demand, taking into account factors such as system resource limitations, technical implementation difficulties, and environmental impacts. For example, in polar scientific research areas, since satellite signals are restricted by extreme weather and environment, the initial feasibility coefficient is 0.5. By optimizing the constellation distribution and low-frequency signal coverage, the adjustment factor is increased to 0.7, so that the system can meet the communication needs of the area.

[0058] The beneficial effects of the above technical solution are: by quantifying the regional characteristics, environmental characteristics, flight characteristics and demand characteristics of each communication network module in multiple dimensions, a comprehensive calculation model of the module shape coefficient is proposed, the complex state of the low-altitude communication network is accurately evaluated, and it is dynamically adapted to different needs and environmental changes, which significantly improves the accuracy, adaptability and reliability of the communication and navigation system.

[0059] Embodiment 7: The embodiment of the present invention provides a low-altitude communication and navigation integrated management system, a communication management module, including: Coefficient determination unit: analyzing the collected surrounding environment data of each communication network module and the device status data of each communication network module to determine the management coefficient of each communication network module; Comprehensive analysis unit: determines the comprehensive management coefficient based on the management coefficient of each communication network module and a preset algorithm; Strategy determination unit: determines the corresponding low-altitude communication navigation management strategy based on the comprehensive management coefficient and the preset coefficient-strategy database.

[0060] In this embodiment, the management coefficient is a quantitative evaluation of the operating status, surrounding environment, equipment performance and other factors of a single module in a satellite communication network. It reflects the current operating efficiency and resource requirements of the module. The management coefficient comprehensively considers signal strength, equipment health status, environmental impact (such as meteorology, electromagnetic interference) and current task load. For example, the communication module of a low-orbit satellite is currently operating in a high-load state (50% of the bandwidth has been allocated), and the equipment temperature is monitored to be high (accounting for 80% of the maximum operating temperature), and there is strong electromagnetic interference in the coverage area. Through analysis, the management coefficient is set to 0.6, indicating that the module needs to be load optimized and maintained.

[0061] In this embodiment, the preset algorithm is used to comprehensively analyze the rules and models of the management coefficients of each module, and combines multi-dimensional data (such as module load, electromagnetic environment, and communication requirements) to perform dynamic weight calculations to obtain a comprehensive management coefficient. Common algorithms include weighted average algorithms, fuzzy logic models, and machine learning prediction models. For example: In satellite cluster management, the preset algorithm uses a fuzzy logic model to calculate a comprehensive score based on the module management coefficients (such as signal strength weight 0.4, device health weight 0.3, and task priority weight 0.3). If the signal strength of module A is 0.8, the device health is 0.6, and the task priority is 0.9, the preset algorithm calculates a comprehensive score of: 0.77; In this embodiment, the comprehensive management coefficient is a global quantitative evaluation of the state of the entire satellite communication network (or its subset), which is obtained based on the management coefficients of all communication network modules and reflects the real-time operation status and task satisfaction capability of the entire network. It determines the allocation of communication resources and the selection of optimization strategies. For example, a low-altitude communication network includes 5 satellite modules, and their management coefficients are 0.7, 0.6, 0.8, 0.9, and 0.5 respectively. The comprehensive management coefficient is calculated by the preset weighted average algorithm as: 0.7. The comprehensive management coefficient is 0.7, indicating that the current network is in a normal load state, and part of the spare bandwidth can be allocated to high-priority tasks as needed.

[0062] In this embodiment, the preset coefficient-strategy database is a predefined rule base that corresponds the comprehensive management coefficient (or correlation coefficient interval) to the communication management strategy. It provides optimization solutions for different network states through mapping relationships, including strategies such as bandwidth allocation, task priority adjustment, and fault repair scheduling. Example: The content of the coefficient-strategy database is as follows: Comprehensive management coefficient>0.8: The system is stable and the existing resource allocation strategy is maintained. 0.6 ≤ Comprehensive management coefficient≤0.8: Light load, reallocate bandwidth, and give priority to high-priority communication tasks. Comprehensive management coefficient<0.6: High load or abnormal state, enable backup satellite resources, and perform fault diagnosis. In the above example, if the comprehensive management coefficient is 0.7, the system will select the "reallocate bandwidth" strategy from the database to give priority to supporting the real-time navigation task of the logistics drone.

[0063] The beneficial effects of the above technical solution are: by introducing management coefficients and comprehensive management coefficients, based on multi-module environment and equipment status data, dynamically evaluating the operation status of the communication network, and combining the coefficient-strategy database to intelligently match the optimal management strategy, it realizes the adaptive optimization management of the low-altitude communication navigation system, improves the communication stability, resource utilization efficiency and task execution accuracy in complex environments, and has the innovative advantages of strong real-time performance and intelligent decision-making.

[0065] The beneficial effects of the above technical solution are: through demand analysis, network division, dynamic configuration and data collection, accurate division and efficient deployment of communication networks in low-altitude flight areas are achieved, and real-time monitoring of the environment and equipment status by sensor networks is combined to improve the system's perception capabilities; based on analysis and optimization of collected data, dynamic communication and navigation management strategies are formulated to improve the system's flexibility, adaptability and reliability, and effectively solve the problems of multi-scenario adaptation and low management efficiency in existing technologies.
