[0002] In existing technologies, the construction of low-altitude aircraft communication networks faces challenges in dynamic environments and resource constraints. Traditional network systems typically rely on fixed communication infrastructure or predefined communication paths, making it difficult to adapt to the needs of low-altitude aircraft in high-speed, dynamic environments. These networks lack dynamic adjustment capabilities in resource allocation and path planning, and are prone to communication congestion or resource waste. In addition, existing optimization solutions for aircraft networks often target a single dimension and fail to fully integrate the real-time status of aircraft and environmental information for comprehensive optimization. This results in insufficient adaptability and poor stability of the communication network, making it difficult to meet the needs of multi-aircraft collaborative communication and dynamic missions.

[0026] Example 2: An embodiment of the present invention provides a dynamically adaptive low-altitude flight communication network system, including a monitoring module, comprising: Real-time sub-state information unit: collects real-time sub-state information of each low-altitude aircraft in the communication network system within the current specified time period, wherein the real-time sub-state information includes the real-time position, real-time altitude, real-time speed of the low-altitude aircraft and the actual communication route determined in the previous specified time period before the current specified time period; Real-time status information unit: determines real-time status information based on the real-time sub-status information of all low-altitude aircraft in the communication network system; Real-time sub-environment information unit: collects real-time sub-environment information of each low-altitude aircraft in the communication network system within the current specified time period.

[0028] In this embodiment, the actual communication route of the last specified time period, that is, the actual optimal data transmission path determined for each aircraft in the last period, is used as a reference input to optimize the communication decision of the current period.

[0029] In this embodiment, the real-time sub-environment information of all aircraft is aggregated and combined with the second communication network structure of the previous time period to dynamically generate the real-time environment information of the entire system.

[0030] In this embodiment, the real-time sub-status information represents the operational status details of a single aircraft in the current time period.

[0035] Example 3: An embodiment of the present invention provides a dynamically adaptive low-altitude flight communication network system, a routing module, including: The first node location unit is used to determine whether any node in the optimal communication route of the low-altitude aircraft in the previous specified time period of the current specified time period is consistent with the real-time position of the low-altitude aircraft. If so, the node in the optimal communication route that is consistent with the real-time position of the low-altitude aircraft is determined to be the node at the first node position of the optimal path of the current specified time period. If not, the node in the optimal communication route that is closest to the real-time position of the low-altitude aircraft is determined to be the node at the first node position of the optimal path of the current specified time period. Second node position unit: determine the next node of the node at the first node position of the low-altitude aircraft in the optimal communication route of the previous specified time period of the current specified time period, and regard it as the node at the second node position of the optimal path of the low-altitude aircraft; A third node location unit: after locking the node position of the last node of the optimal communication route in the optimal path of the low-altitude aircraft, determines the node at the next position of the node position in the optimal path as the first node in the optimal communication route; Optimal path unit: Determine the optimal path for each low-altitude aircraft based on the nodes of all node positions of each low-altitude aircraft; in, represents the optimal path of the i-th low-altitude aircraft, The node representing the first node position of the optimal path for the i-th low-altitude aircraft, The node representing the node position of the jth node position of the optimal path of the i-th low-altitude aircraft, The node representing the iN1th node position of the optimal path of the i-th low-altitude aircraft, iN1 represents the number of node positions of the optimal path of the i-th low-altitude aircraft; Actual communication routing unit: determines the actual communication route of each low-altitude aircraft based on the optimal path, real-time status information and real-time environmental information of each low-altitude aircraft.

[0036] In this embodiment, the optimal communication route node positions of the aircraft in the current specified time period and the previous specified time period are compared to determine whether the current real-time position of the aircraft is consistent with a node in the optimal communication route of the previous period. If they are consistent, the node is regarded as the first node of the optimal path of the current period; if they are inconsistent, the optimal communication route node of the previous period that is closest to the real-time position of the aircraft is selected as the first node of the optimal path, ensuring that the aircraft can start path selection based on its actual position.

[0037] In this embodiment, once the first node is determined, the next node after the first node is determined from the optimal communication route of the previous cycle and used as the second node of the optimal path of the current cycle. This step helps maintain the continuity and stability of the communication link by continuing along the historical optimal path.

[0038] In this embodiment, when the aircraft has approached the end point along the optimal communication route, the position of the last node in the optimal path is locked, and the next node thereafter is determined as the first node of the optimal communication route, which means that the communication path is circular.

[0039] In this embodiment, each aircraft determines the nodes at all node positions to generate the optimal path for each aircraft.

[0040] In this embodiment, for example: the optimal communication path of the i-th low-altitude aircraft is {node 1, node 2, node 3, ..., node iN1}, the node at the first node position of the optimal path of the i-th low-altitude aircraft is determined to be node 2 in the corresponding optimal communication route, then the node at the second node position of the optimal path of the i-th low-altitude aircraft is determined to be node 3 in the corresponding optimal communication route, after locking the position of node iN1 in the optimal communication route of the i-th low-altitude aircraft in the corresponding optimal path, node 1 in the optimal communication route of the i-th low-altitude aircraft is determined to be the node at the next node position of the node position of node iN1 in the corresponding optimal path, and the node optimal path determined based on all node positions of the i-th low-altitude aircraft is expressed as {node 2, node 3, ..., node iN1, node 1} The beneficial effects of the above technical solution are: based on real-time status information and real-time environmental information, the optimal path for each low-altitude aircraft is determined, and the actual communication route of each low-altitude aircraft is determined, which can improve the accuracy of low-altitude aircraft path selection, make the network system more flexible and intelligent in responding to environmental changes, enhance the sustainability of the path, and adapt to complex flight and communication environments.

[0042] In this embodiment, when the availability value of a node path is 0, the path is determined to be a failed path, and the system will search for an alternative adjustment path based on the current real-time status and environmental information to ensure that aircraft communication is not interrupted.

[0043] In this embodiment, the actual communication route is determined based on the following paths: In this embodiment, all node paths with an availability value of 1 are normal working paths; and the adjustment paths corresponding to node paths with an availability value of 0 are backup paths that replace failed paths. Combining the above two types of paths, the actual communication route for each low-altitude aircraft is generated.

[0044] In this embodiment, the distance of the node path represents the physical straight-line distance between two communication nodes.

[0045] In this embodiment, the received power indicates the signal power at the receiving end on the communication link, reflecting the signal strength and transmission quality.

[0046] In this embodiment, the interference power indicates the power of other signal interferences that a communication link experiences during signal transmission.

[0047] In this embodiment, the available value indicates a status identifier of a node path. An available value of 1 indicates that the path is available, and an available value of 0 indicates that the path is invalid.

[0048] In this embodiment, the adjustment path is used as a backup communication path to replace the failed path.

[0061] In this embodiment, every two nodes in the optimal path of each low-altitude aircraft correspond to one available value.

[0062] In this embodiment, if any one of the distance factor, the channel quality factor, and the interference factor is 0, the corresponding available values ​​of the two nodes of the optimal path of the low-altitude aircraft are 0.

[0063] The beneficial effects of the above technical solution are: determining the available value of the node path between every two nodes in the optimal path of each low-altitude aircraft can provide a data basis for determining the actual communication route, dynamically optimize the path, and ensure the scientificity and accuracy of the route selection.

[0064] Example 8: An embodiment of the present invention provides a dynamically adaptive low-altitude flight communication network system, including a determination module, comprising: A region division unit is configured to divide the first communication network structure into regions, and determine the communication resources of each divided region after the region division in combination with the optimal communication routes of all low-altitude aircraft; Identification unit: identifies the communication resources of each partitioned area, and determines the partitioned area where communication information is overloaded and the partitioned area where communication information is redundant; An area segmentation unit is configured to segment the area where the communication resource is overloaded to obtain a plurality of segmented sub-areas, and perform a first marking; An area merging unit is configured to determine an adjacent area with the smallest communication resource among all adjacent areas of the divided area with redundant communication resources, and perform area merging and second marking on the adjacent area with the corresponding divided area with redundant communication resources; A second communication network structure unit is configured to determine a second communication network structure based on the first marking result, the second marking result, and all divided areas that have not been marked by the first marking and the second marking.

[0065] In this embodiment, each divided sub-area, merged area, and partitioned area in the second communication network structure uses independent or shared network resources, and adjusts its network connection according to the movement of the aircraft through different areas.

[0066] In this embodiment, the first communication network structure is divided into regions according to geographical locations, and the communication resources (including bandwidth, power, number of nodes, etc.) of each divided region are determined in combination with the optimal communication routes of all low-altitude aircraft.

[0067] In this embodiment, the communication information overload area represents an area where resource demand exceeds available communication resources, resulting in congestion.

[0068] In this embodiment, the communication information redundant area represents an area where resource demand is far lower than resource supply, and resources are underutilized.

[0069] In this embodiment, the area where communication resources are overloaded is divided into multiple sub-areas to disperse the load. Intelligent segmentation is performed according to the distribution characteristics of communication resources (such as load density, node distribution, etc.). Each sub-area is allocated independent communication resources. The divided area is given a first mark to facilitate identification during subsequent network structure optimization.

[0070] In this embodiment, the divided areas with redundant communication resources are merged with the adjacent areas with the smallest communication resources. Through resource evaluation, the adjacent areas with the smallest resources are selected for merging to form a new merged area. The merged area is given a second tag to facilitate network structure optimization and identification.

[0071] In this embodiment, the results of all area adjustments are integrated to construct a new communication network structure: first marked area: the divided sub-areas of the communication resource overload area are incorporated into the new network; second marked area: the area after the communication resource redundant areas are merged is incorporated into the new network; unmarked area: the original divided areas are directly incorporated into the new network.

[0072] The beneficial effects of the above technical solution are: determining the second communication network structure of the communication network based on the optimal communication routes of all low-altitude aircraft and the first pass network structure can enhance the sustainability of the path, improve the scientificity and accuracy of route selection, enhance the adaptability, stability and resource utilization efficiency of the communication network, meet the communication needs in complex dynamic environments, and improve the adaptability and robustness of communication routes and network structures in complex environments.
