[0045] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] The aircraft route control method provided in this application is applied to an aircraft route control system based on A2X (Aircraft to Everything) direct communication. Figure 1 The block diagram of the aircraft route control system based on A2X direct communication provided for this application is composed of multiple subsystems, each of which works together to ensure the efficient operation of aircraft such as drones and eVTOL in complex low-altitude airspace environments. The system includes: airspace management system (UTM / U-Space), ground base station network system, automated flight and route planning system, emergency response and obstacle avoidance system, and low-altitude airspace aircraft.

[0047] Among them, the airspace management system is responsible for airspace authorization, flight planning, conflict detection and obstacle avoidance management, and mainly includes: airspace optimization and authorization module, conflict detection and avoidance module and formation management and collaboration module. Among them, the airspace optimization and authorization module is used to analyze the use of airspace, issue flight authorization and optimized routes to drones; the conflict detection and avoidance module is used to monitor the airspace in real time, detect potential conflicts between aircraft, and provide avoidance instructions; the formation management and collaboration module is used to manage the formation flight of drones and eVTOLs, coordinate formation formations, and allocate and adjust tasks.

[0048] The ground base station network system includes communication base stations and edge computing nodes, which are responsible for receiving aircraft data, performing route optimization and conflict detection, assisting aircraft in complex computing tasks, and processing communications between aircraft and airspace management systems. The ground base station network system not only has traditional communication functions, but also has A2X direct communication capabilities, allowing aircraft to communicate with other aircraft or base stations through base stations.

[0049] The automated flight and route planning system is responsible for generating and optimizing the drone's route and providing the optimal path based on mission requirements, airspace usage and flight data.

[0050] The emergency response and obstacle avoidance system monitors the flight environment in real time and automatically adjusts the flight path according to emergencies (such as weather, obstacles, and other aircraft) to ensure safety.

[0051] The low-altitude airspace aircraft includes an A2X direct communication module, a flight navigation module and a real-time monitoring module. Among them, the flight navigation module is used for navigation and heading control, and receives route planning instructions from the airspace management system; the real-time monitoring module is used to obtain flight data (such as position, speed, altitude) in real time and feed it back to the airspace management system or the ground base station network system; the A2X direct communication module is used to communicate directly with other aircraft, ground base station network systems, and airspace management systems within the preset airspace range, and exchange real-time location information, flight status, and formation data. Preferably, the direct communication interface is 3GPPPC5.

[0052] In the pre-flight stage, after the drone or eVTOL is started, it applies for airspace authorization from the airspace management system and submits a flight plan; the airspace management system generates an initial route based on the current airspace status and aircraft mission requirements, and sends it to the aircraft. Figure 2 A flowchart of the route control during the pre-flight phase of a drone flight is provided for this application.

[0053] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0054] In a first aspect, an embodiment of the present application provides an aircraft route control method.

[0055] In one embodiment, referring to Figure 3 , Figure 3 This is a flow chart of the first embodiment of the aircraft route control method of the present application. Figure 3 As shown, the aircraft route control method includes:

[0056] Step 310: for each aircraft in the low-altitude airspace, based on the spatial position coordinates of the aircraft itself and the spatial position coordinates of each aircraft in the preset airspace, calculate a first distance between the aircraft and each aircraft in the preset airspace, wherein the aircraft exchange first information in a direct communication manner, and the first information includes the spatial position coordinates of the aircraft;

[0057] The preset airspace range is a spherical range or a rectangular range with the aircraft itself as the center point.

[0058] During specific implementation, each aircraft in the low-altitude airspace establishes a direct communication link with the direct communication modules of other aircraft in the preset airspace during the flight stage to achieve first information exchange, where the first information includes the spatial position coordinates and route of the aircraft.

[0059] Each aircraft dynamically calculates the first distance between the aircraft based on its own spatial position coordinates and the spatial position coordinates of each aircraft within the preset airspace range obtained through the ACX direct connection module. The formula corresponding to calculating the first distance is:

[0060]

[0061] Among them, C ij is the first distance between the i-th aircraft and the j-th aircraft, (x i ,y i ,z i ) is the spatial position coordinate of the i-th aircraft, (x j ,y j ,z j ) is the spatial position coordinate of the j-th aircraft.

[0062] Step 320: determine whether each first distance is less than a preset distance threshold;

[0063] Step 330: When the first distance is less than a preset distance threshold, an obstacle avoidance program is triggered to improve the safety of the aircraft.

[0064] Furthermore, whether there is a risk of conflict is detected by judging whether each first distance is less than a preset distance threshold. It can be understood that when all first distances are greater than the preset distance threshold, it is determined that there is no risk of conflict; when there is a first distance less than the preset distance threshold, it is determined that there is a risk of conflict, and it is necessary to trigger the obstacle avoidance program to adjust the route to avoid obstacles, thereby improving the safety of the aircraft.

[0065] In this embodiment, for each aircraft in the low-altitude airspace, the first distance between the aircraft and each aircraft within the preset airspace is calculated based on the spatial position coordinates of the aircraft itself and the spatial position coordinates of each aircraft within the preset airspace, wherein the aircraft exchange first information in a direct communication manner, and the first information includes the spatial position coordinates of the aircraft; it is determined whether each first distance is less than a preset distance threshold; when there is a first distance less than the preset distance threshold, an obstacle avoidance program is triggered. The present application adopts a real-time, low-latency direct communication method to enable rapid data exchange between aircraft, achieve efficient conflict detection, and improve the safety of aircraft.

[0066] When each aircraft in the low-altitude airspace is in flight, if the aircraft computing power is insufficient or the low-altitude airspace is congested, the drone can request edge computing support from the edge computing node, and there will be frequent data interaction between the edge computing node and the ground base station. After the aircraft requests edge computing support, the edge computing node collaborates with the UTM through the ground base station to process complex tasks, such as formation planning, route optimization, and conflict detection.

[0067] Among them, UTM plays an important role in each link of formation route optimization, dynamic task adjustment, conflict detection and formation disbanding, ensuring that each decision meets airspace management requirements and avoids conflicts with other aircraft or formations. UTM will feed back airspace management information to the ground base station network system and edge computing nodes at each stage.

[0068] Furthermore, in one embodiment, the calculating the first distance between the aircraft and each aircraft within the preset airspace includes:

[0069] When the computing power of the aircraft is insufficient, the first distance between the aircraft and each aircraft within the preset airspace is calculated through the edge computing node in the ground base station network system.

[0070] In specific implementation, if the aircraft computing power is insufficient during the flight phase, complex computing tasks can be offloaded to the ground base station network system. Complex computing tasks include calculating the first distance between the aircraft and each aircraft within the preset airspace, optimizing the formation route, determining the target formation of the aircraft to be formed, etc., and implementing relevant detection with the assistance of the ground base station network system. In airspace congestion or other potential conflicts, the edge computing node works in conjunction with the ground base station network system and UTM to ensure rapid response.

[0071] In this embodiment, when the computing power of the aircraft is insufficient, the first distance between the aircraft and each aircraft within the preset airspace is calculated through the edge computing node in the ground base station network system, thereby offloading the computing task to the ground base station network system, reducing its own computing power burden, and improving flight efficiency. The ground base station network system assists in conflict detection, realizes efficient conflict detection, and improves the safety of the aircraft.

[0072] Furthermore, in one embodiment, the method further includes:

[0073] In the case of congestion in the low-altitude airspace, the optimized route of each formation in the low-altitude airspace is calculated by the edge computing nodes in the ground base station network system, so that each formation can adjust from the current route to the optimized route. The formation is composed of several aircraft whose route similarity is greater than the similarity threshold.

[0074] Among them, the route similarity is determined based on the take-off point, route point and destination of each aircraft in the formation.

[0075] For example, a formation composed of several drones whose route similarity is greater than the similarity threshold is taken as an example. In the case of congestion in the low-altitude airspace, the formation pilot drone requests edge computing support from the edge computing node in the ground base station network system according to mission requirements and airspace environment changes. The edge computing node first determines at least two alternative routes based on the current route of the formation; then determines the optimal route from the alternative routes; finally, through the ground base station and UTM collaboration, the optimized route is fed back to the formation pilot drone. The formation pilot drone then transmits the optimized route to each member of the formation in a direct communication manner, so that the formation can adjust from the current route to the optimized route.

[0076] Similarly, the formation disbanding process is that the formation leading drone requests edge computing support from the edge computing node in the ground base station network system to assist in analyzing the disbanding timing based on the mission completion status and environmental changes. The UTM approves and feeds back the disbanding data to ensure the flight safety of the drone after disbanding.

[0077] In this embodiment, when there is congestion in the low-altitude airspace, the optimized routes of each formation in the low-altitude airspace are calculated by the edge computing nodes in the ground base station network system, so that each formation can adjust from the current route to the optimized route, thereby offloading the computing tasks to the ground base station network system, reducing its own computing power burden, and improving flight efficiency. The ground base station network system assists in optimizing the routes of formations in the low-altitude airspace, realizes real-time adjustment of routes, and ensures the efficiency and safety of the routes.

[0078] Further, in one embodiment, the calculating of the optimized routes of each formation in the low-altitude airspace includes:

[0079] Step 410: for each formation, determine at least two alternative routes based on the current route of the formation;

[0080] In the specific implementation, for each formation, assuming that the current route of the formation is from departure point A to destination D, while ensuring departure point A and destination D, the determined alternative route can be departure point A-travel point B-destination D, the alternative route can also be departure point A-travel point C-destination D, etc.

[0081] Step 420, calculating the economic safety quantitative index corresponding to the alternative route based on the safety weight, the safety factor of each aircraft in the formation on each alternative route, the flight cost and the flight time;

[0082] During specific implementation, the safety weight, the safety factor of each aircraft in the formation on each alternative route, the flight cost and the flight time are substituted into the calculation formula to calculate the quantitative economic safety indicators corresponding to the alternative routes.

[0083] The calculation formula is:

[0084]

[0085] Among them, f is the alternative route, n is the total number of aircraft in the formation, A f is the economic safety quantitative index corresponding to the alternative route f, C i is the flight cost of the i-th aircraft in the formation on the alternative route f, t i is the flight time of the i-th aircraft in the formation on the alternative route f, λ is the safety weight, S i is the safety factor of the i-th aircraft in the formation on the alternative route f. λ is a calibration value and can be flexibly set according to actual needs.

[0086] Step 430: determine the minimum value of each economic safety quantitative index, and use the alternative route corresponding to the minimum value as the optimized route.

[0087] After obtaining the economic safety quantitative index corresponding to each alternative route, the minimum value is determined from each economic safety quantitative index, and the alternative route corresponding to the minimum value is used as the optimized route.

[0088] In this embodiment, it is specifically provided how to calculate the optimized routes of each formation in the low-altitude airspace, so as to quickly determine the optimized routes and ensure the efficiency and safety of the routes.

[0089] Furthermore, in one embodiment, the method further includes:

[0090] In the case of congestion in the low-altitude airspace, the target formation of each aircraft to be formed in the low-altitude airspace is calculated through the edge computing nodes in the ground base station network system, so that the aircraft to be formed can join the target formation, which is composed of several aircraft whose route similarity is greater than the similarity threshold.

[0091] In the case of congestion in low-altitude airspace, the aircraft to be formed requests edge computing support from the edge computing node in the ground base station network system to determine the target formation. The edge computing node first determines at least two alternative formations based on the current route of the aircraft to be formed; then determines the target formation from the alternative formations; finally, through the collaboration of the ground base station and UTM, the target formation is fed back to the aircraft to be formed and the pilot drone of the target formation. Then the pilot drone of the target formation transmits the information to each member of the formation in a direct communication mode, so that the aircraft to be formed can join the target formation.

[0092] In this embodiment, when there is congestion in the low-altitude airspace, the target formation of each aircraft to be formed in the low-altitude airspace is calculated by the edge computing nodes in the ground base station network system, so that the aircraft to be formed can join the target formation, thereby offloading the computing tasks to the ground base station network system, reducing its own computing power burden, and improving flight efficiency. The ground base station network system assists in determining the target formation of the aircraft to be formed, which can effectively improve the efficiency of airspace utilization, reduce energy consumption, and realize dynamic adjustment of the target formation.

[0093] Furthermore, in one embodiment, the calculation of the target formation of each aircraft to be formed in the low-altitude airspace includes:

[0094] Step 510: Determine at least two candidate formations based on the current routes of the aircraft to be formed;

[0095] In the specific implementation, assuming that the current route of the aircraft to be formed is from departure point A to destination D, while ensuring departure point A and destination D, the formation with the route of departure point A-travel point B-destination D can be used as an alternative formation, or the formation with the route of departure point A-travel point C-destination D can be used as an alternative formation, and so on.

[0096] Step 520: for each candidate formation, based on the formation compactness weight, the distance between the aircraft to be formed and each aircraft in the candidate formation, and the energy consumption of each aircraft in the candidate formation, calculate the energy consumption safety quantitative index corresponding to the candidate formation;

[0097] During the specific implementation, for each alternative formation, the formation compactness weight, the distance between the aircraft to be formed and each aircraft in the alternative formation, and the energy consumption of each aircraft in the alternative formation are substituted into the corresponding calculation formula to calculate the energy consumption safety quantitative index corresponding to the alternative formation.

[0098] The calculation formula is:

[0099]

[0100] Among them, d is the alternative formation, m is the total number of aircraft in the alternative formation, B d is the energy consumption safety quantitative index corresponding to the alternative formation d, E k is the energy consumption of the kth aircraft in the alternative formation on the alternative formation d, α is the formation compactness weight, D k is the distance between the aircraft to be formed and the kth aircraft in the candidate formation. α is a calibration value, which can be flexibly set according to actual needs.

[0101] Step 530: determine the minimum value among the energy consumption safety quantitative indicators, and use the alternative formation corresponding to the minimum value as the target formation.

[0102] After obtaining the energy consumption safety quantitative index corresponding to each alternative formation, the minimum value is determined from each energy consumption safety quantitative index, and the alternative formation corresponding to the minimum value is used as the target formation.

[0103] In this embodiment, a specific method of determining the target formation of each aircraft to be formed in the low-altitude airspace is given to ensure that a safe distance can be maintained while reducing energy consumption during formation flight, thereby achieving rapid determination of the target formation of the aircraft to be formed.

[0105] In the post-flight phase, after the aircraft completes the flight mission, it reports the mission status and flight data to the airspace management system. The flight data is uploaded to the airspace management system, and the airspace management system optimizes the use of airspace based on the flight data.

[0106] In a second aspect, an embodiment of the present application also provides an aircraft route control device.

[0108] The first calculation module 601 is used to calculate, for each aircraft in the low-altitude airspace, a first distance between the aircraft and each aircraft within the preset airspace based on the spatial position coordinates of the aircraft itself and the spatial position coordinates of each aircraft within the preset airspace, wherein the aircraft exchange first information in a direct communication manner, and the first information includes the spatial position coordinates of the aircraft;

[0111] Furthermore, in one embodiment, the first calculation module is specifically used for:

[0112] When the computing power of the aircraft is insufficient, the first distance between the aircraft and each aircraft within the preset airspace is calculated through the edge computing node in the ground base station network system.
