Embodiment 1

[0095] For the efficient layered network access management method and equipment of aircraft formations provided by the embodiments of the present invention, refer to image 3 The implementation steps are as follows:

[0096] Step 1, network scene description:

[0097] In a mission-driven scenario, aircraft formations receive TT&C commands from ground stations or satellites to fly to designated areas, and initiate network access to another aircraft network. Among them, the aircraft formations that actively initiate network access are called formations to be networked, and will be responsible for the formations to be networked. The aircraft network under certification management is called the main topology. The invention uses an improved mechanism to achieve fast, efficient and accurate certification and integration of formations, so as to ensure the high efficiency of task execution and improve network robustness;

[0098] Step 2, initialize aircraft network parameters

Embodiment 2

[0151] The high-efficiency layered network access management method and equipment based on the aircraft formation are the same as in Embodiment 1. The method for constructing the visual map of the entire network node capabilities in the present invention will be described in detail below in conjunction with specific scenarios. See Figure 4 .

[0152] The picture shows the network scene of the formation to be networked. There is a detection area of ​​πr within a range of 600km*600km 2 km 2 There are 6 aircraft nodes in the aircraft formation FA in the formation, then identify the capability state variables for the nodes in the formation, and the process of constructing the capability visual map is shown in the figure, and the specific steps are as follows:

[0153] Step 1: Perform parameter initialization and identify node capability status information

[0154] According to the parameters, the parameters obtained by the message acquirer module GT through perception and infor...

Embodiment 3

[0159] The efficient layered network access management method and equipment based on aircraft formation are the same as those in Embodiment 1. The method for selecting the network access initiating node org_node in the present invention will be described in detail below in combination with specific scenarios. see Figure 5 .

[0160] Scenario 1: The formation to be connected to the network is small in scale, and all aircraft nodes in the formation need to join the main topology network to cooperate to complete specified tasks;

[0161] Scenario description: as Figure 5 For the network scenario of the formation to be networked, there is a detection area πr within a range of 600km*600km 2 km 2 The aircraft formation FA of the aircraft, where r=25km, there are 6 aircraft nodes in the formation, and the communication radius of one hop of nodes is rad=20km, then the process of selecting the network initiation node org_node for the formation to be connected to the network is sho...

Abstract

The invention belongs to the technical field of equipment maintenance or management, and discloses an aircraft formation hierarchical network access management method and system. The management methodincludes the following steps: initializing aircraft formation network parameters; identifying aircraft node capability state information; defining node comprehensive property parameter indexes by using the node capability state information; constructing a whole network node capability visibility graph according to the comprehensive property parameter indexes; selecting a formation network accessinitiation node according to the consideration of the node capability visibility graph and the geographical location area; completing control information interaction between the network access initiation node and a main topology central control node according to the principle of minimum hop count and a sleep state multipath way-finding mode based on geographic location information; and carrying out information in a formation after the network access initiation node receives network access response so as to make the nodes update a local information field to finish the formation network access.According to the invention, maximum network access efficiency is obtained with lowest cost, the comprehensive performance of formation network access is improved, network communication QoS needs are guaranteed, and the task completion efficiency and quality are improved.

Description

technical field [0001] The invention belongs to the technical field of devices used for maintenance or management, and in particular relates to a method and system for aircraft formation layered network access management. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: The air information platform is a high-speed mobile space platform, and it is a communication service and mission planning system that supports important missions such as surveying, communication, and reconnaissance, including various low-altitude aircraft. Compared with the wired network and ground wireless local area network, the aircraft in the air information platform has unique network characteristics: limited resources, susceptible to the influence of the communication environment, and highly dynamic changes in the network topology. On the other hand, it also brings great challenges to the QoS guarantee of network communication service qu...
