[0052] The present application is further described in detail below in conjunction with the accompanying drawings.
[0053] In one embodiment, if Figure 1 As shown, the present application discloses a method for analyzing the development forms of low-altitude economy based on high-density cities, which specifically includes the following steps:
[0054] S10: Obtain mission address information and mission type information of each aircraft, and perform path planning within a preset airspace according to the mission address information and mission type information to obtain flight path information of each aircraft.
[0055] Specifically, the mission address information and mission type information of the aircraft are extracted, and the mission address information is formatted to match the airspace data. The mission priorities are divided according to the mission type to facilitate flexible priority management in path planning. During the path planning process, the paths are reasonably allocated according to the airspace restrictions within the preset airspace range. The smooth execution of various tasks is guaranteed while meeting the flight safety requirements. Through a comprehensive assessment of the mission requirements and airspace conditions, a preliminary path plan that meets the flight mission requirements is planned.
[0056] S20: Obtain real-time traffic flow and airspace status information within a preset airspace range, and optimize and adjust the flight path information in real time based on the real-time traffic flow and airspace status information.
[0057] Specifically, real-time data on traffic flow and airspace conditions are obtained within the airspace, and path planning settings are dynamically adjusted according to the current flight density and traffic conditions in the airspace to ensure safe spacing and smooth operation between aircraft. Each flight path is automatically optimized based on the real-time data, and the speed and route of the aircraft are adjusted to adapt to the current airspace conditions. When necessary, airspace resources are reallocated to ensure the applicability of the flight path in a high-density environment.
[0058] S30: Monitor the activities of aircraft in the airspace in real time, obtain flight information of each aircraft, and determine whether the corresponding aircraft has any flight violations based on the flight information.
[0059] Specifically, the real-time position information, speed and route trajectory of aircraft in the airspace are obtained, and by comparing the real-time flight data of the aircraft with the preset path information, it is determined whether there is any deviation from the path or non-compliance with flight rules. During the monitoring process, continuous judgments are made on flight altitude, speed limit and other conditions to identify whether the aircraft has any violations, thereby ensuring that all aircraft in the airspace operate according to the planned route and specified speed.
[0060] S40: Provides real-time tracking and feedback of flight mission status, and monitors the aircraft status and equipment operation in the airspace. In the event of an abnormality, it triggers equipment alarms and takes preset emergency response measures.
[0061] Specifically, it monitors the mission progress and current status of the aircraft in real time, including battery power, signal strength and location information. When encountering abnormal situations, it triggers an alarm signal according to the preset alarm conditions and sends emergency processing instructions. If necessary, it issues return or landing instructions to ensure the safety of the aircraft, and records relevant information for subsequent analysis and processing.
[0062] In one embodiment, if Figure 2 As shown, before step S10, that is, before performing path planning within a preset airspace according to the task address information and the task type information, it also includes:
[0063] S101: Based on the preset city map database and airspace distribution data, a GIS module is used to divide the airspace into no-fly zones, suitable-fly zones, and airspace available zones.
[0064] Specifically, the city map database and airspace distribution data are imported into the GIS module, and the city’s geographical location, building distribution and traffic conditions are marked through map parsing tools. Different types of areas such as no-fly zones, suitable flying zones, and available flight routes are specifically divided. The boundary lines and boundary points of each area are marked in the GIS module, and an airspace distribution map suitable for low-altitude aircraft is created. These area data are stored in the path planning database for reference in subsequent path planning, so that the aircraft can follow the distribution division in actual flight.
[0065] S102: Divide the regions according to different airspaces and establish boundary conditions for flight path planning.
[0066] Specifically, the data of airspace areas such as no-fly zones and suitable flying zones are converted into boundary conditions for path planning, and different entry and obstacle avoidance rules are set according to the attributes of each area. Path entry conditions are set during the path planning process to prevent the aircraft from entering no-fly zones or unsuitable airspace areas. Flight altitude, speed limit and other conditions are set for the paths in suitable flying zones. A specific path planning rule set is created to dynamically call the boundary conditions during path calculation, ensuring that the path planning process completes the optimal calculation and reasonable planning of the path within the set airspace rules.
[0067] In one embodiment, if Figure 3 As shown, in step S10, path planning is performed within a preset airspace according to the mission address information and the mission type information to obtain flight path information of each aircraft, specifically including:
[0068] S11: Convert the task address information into a geographic coordinate format, and map the task type information into a corresponding priority identifier.
[0069] Specifically, the mission address information is extracted and converted into standardized geographic coordinate data through a geocoding tool, the geographic coordinate information is entered into the aircraft path database to ensure that it can match the geographic information data in the preset airspace range, the mission type information is compared with the data in the priority identification table to generate a corresponding priority identification, and it is attached to the path planning conditions of the mission, so that the path planning can dynamically adjust the priority of the flight path according to the importance of the mission during execution, and provide basic mission data for subsequent path optimization.
[0070] S12: Match the geographical coordinates of the mission address with the geographical information within the preset airspace, combine the priority identification determined by the aircraft mission type, and establish obstacle avoidance rules based on the boundary conditions of the flight path planning.
[0071] Specifically, the converted geographic coordinates of the mission address are automatically matched with the airspace range data, the position of the address point in the airspace distribution is analyzed, and the obstacle avoidance rules for path planning are established according to the mission priority identification. The paths of no-fly zones, suitable flying zones and obstacle-dense areas are screened and excluded. In path planning, the boundary conditions for aircraft entry or avoidance are set with reference to the priority identification. In combination with airspace restrictions, path guidance for tasks of different priorities is generated to form a final obstacle avoidance plan and output it to the path planning system for application.
[0072] S13: Calculate the optimal path for each aircraft based on the Dijkstra algorithm, match the mission address information with the preset airspace range, and generate optimal flight path information suitable for missions of different priorities.
[0073] Specifically, the Dijkstra algorithm is called during the path calculation process, and the mission address point, path nodes in the airspace range and boundary conditions are input into the algorithm. Priority weights are set so that the algorithm gives priority to important tasks and safe airspace nodes. The optimal path is generated based on the path weights and the connection relationship between the nodes. The path weights are calculated and updated in real time during the algorithm iteration process. After each path is generated, safety checks are performed on key points in the path to ensure that the path plan adapts to the priority and airspace distribution of the current task. Finally, the optimal flight path is generated and stored in the path database so that the aircraft can perform the flight mission according to the optimal path.
[0074] In one embodiment, if Figure 4 As shown, in step S20, the real-time traffic flow and airspace status information within the preset airspace is obtained, and the flight path information is optimized and adjusted in real time according to the real-time traffic flow and airspace status information, specifically including:
[0075] S21: Collect and calculate real-time airspace traffic based on building density, aircraft quantity and flight speed data within the preset airspace range to obtain traffic density data.
[0076] Specifically, multiple distributed sensors in the airspace continuously collect data on building density, real-time number of aircraft and aircraft speed in the current area, and combine these data to calculate traffic density. The building density data is combined with the aircraft speed and number of flights to generate a dynamic traffic distribution in the airspace. The real-time traffic density data of the current area is calculated based on the traffic calculation model, and the traffic density data is used as the basis for flight path adjustment and provides input for traffic-aware path optimization to ensure the adaptability of real-time traffic in path calculation.
[0077] S22: Through the flow-aware based path optimization algorithm, the flight speed and direction parameters of the flight path information are adjusted according to the flow density data, and the flight spacing and entry times of the aircraft are calculated.
[0078] Specifically, the traffic density data is input into the path optimization algorithm model, and the flight speed is adjusted and the direction parameters are optimized according to the changes in traffic density in different areas. The safety distance between aircraft is measured and adjusted in real time, and the number of times aircraft enter the airspace is counted and restricted to avoid excessive congestion in high-traffic areas. By adjusting the speed and direction parameters of the flight path, the aircraft can adapt to the traffic distribution in the current area and ensure safe operation in the airspace.
[0079] S23: Calculate the traffic changes in different areas based on the traffic density data, and perform dynamic path switching based on the path switching strategy with preset priorities when airspace traffic congestion is detected.
[0080] Specifically, the traffic changes in each airspace area in the traffic density data are analyzed in real time. According to the traffic density changes in the current area, it is determined whether path switching needs to be triggered. The aircraft path is dynamically adjusted through the preset path priority switching strategy, and the aircraft in the traffic congestion area is guided to the area with lower traffic. The airspace load caused by congestion is reduced through dynamic path adjustment. After the path switching is completed, the aircraft's airspace resources are reallocated, thereby realizing effective airspace management.
[0081] In one embodiment, if Figure 5 As shown, in step S20, the flight path information is optimized and adjusted in real time according to the real-time traffic flow and airspace status information, and further includes:
[0082] S201: Acquire the weather data of the current airspace in real time, and adjust the flight speed and altitude of the aircraft according to the weather data to reduce flight deviations caused by adverse weather conditions.
[0083] Specifically, it receives weather data provided by the meteorological monitoring module, including real-time meteorological information such as wind speed, wind direction, temperature and humidity, and adjusts the speed and altitude parameters of the aircraft in real time according to the meteorological conditions of the current airspace. When encountering weather with excessive wind speed or drastic changes in air pressure, it reduces the risk of aircraft yaw in bad weather to a minimum by appropriately adjusting the speed and altitude, thereby ensuring the stability of the aircraft under complex weather conditions.
[0084] S202: Detect the relative distance between the aircrafts through a distance-based detection module, and adjust the flight speed and / or flight direction of the aircraft when the relative distance is less than a preset safety distance threshold.
[0085] Specifically, a distance-based detection module is used to measure the relative position of each aircraft. When the relative distance is less than the set safety distance threshold, the aircraft's flight speed is automatically reduced or the flight direction is changed. Aircraft that are too close are automatically guided to an appropriate distance range. The safety distance is maintained through dynamic distance adjustment to ensure that aircraft remain in a safe flight state in areas with dense aircraft.
[0086] In one embodiment, if Figure 6 As shown, in step S30, the aircraft activities in the airspace are monitored in real time, the flight information of each aircraft is obtained, and it is determined whether the corresponding aircraft has any flight violation according to the flight information, which specifically includes:
[0087] S31: Use a high-frequency radar system to capture the position information, speed information and route trajectory of the aircraft in real time, and determine whether the aircraft has deviated from the preset route by comparing the flight path information.
[0088] Specifically, the high-frequency radar system scans the aircraft position information in the airspace in real time, records the aircraft's speed and route trajectory data, and compares the real-time captured trajectory data with the route information set in the flight path planning. When it is found that the aircraft's position or speed deviates from the preset route, it is judged that the aircraft has deviated, and the deviated aircraft position and speed data are stored, and an early warning process is triggered when the deviation data exceeds the set threshold.
[0089] S32: In combination with the real-time speed data of the aircraft, by comparing the real-time speed data with a preset speed limit value, it is determined whether the flight speed of the aircraft is abnormal.
[0090] Specifically, the real-time speed data of the aircraft is continuously monitored, and the current speed is dynamically compared with the speed limit value according to the speed limit in the flight mission. When it is detected that the speed of the aircraft exceeds the speed limit value, the system records the speed anomaly and triggers the speed control mechanism. On the premise of keeping the aircraft speed within a safe range, it ensures that its operation complies with the speed limit stipulated in the airspace.
[0091] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
