Embodiment 1

[0024] Such as figure 1 As shown, this embodiment proposes a dual-frequency heterogeneous ad hoc network data link, the data link includes a main link and a backup link, the main link is a central star ad hoc network data link (30km), the main The link realizes ad hoc network communication through a ground-end data link transmission unit as a central node and multiple air-end data link encoding transmission units as sub-nodes, and the backup link is a centerless MESH multi-hop ad hoc network data link ( 3km). The main link uses L-band to realize ad hoc network communication, and the backup link uses U-band to realize ad hoc network communication. When a sub-node in the main link has poor channel quality or abnormal link disconnection, the sub-node is connected to the adjacent normal sub-node through the standby link and communicates with the ground-end data link transmission unit through the main link adjacent to the normal sub-node, or In the short distance, the sub-node co...

Abstract

The embodiment of the invention discloses a dual-frequency heterogeneous ad-hoc network data chain, and compared with a traditional single-frequency data chain product, the advantages of a one-to-many ad-hoc network data chain in a double-frequency-band double-networking mode are reflected in reliability and strong real-time performance. A central strong real-time star ad-hoc network data link is used as a main link, the strong real-time performance of communication among platforms and the hot backup of the centerless MESH multi-hop ad-hoc network data link are guaranteed, the advantages of random access exit and random relay of the MESH ad-hoc network are fully utilized, the obstacle avoidance capability of the system is improved, and the working reliability of the equipment main link under the condition of interference or shielding is guaranteed.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a dual-frequency heterogeneous ad hoc network data link. Background technique [0002] At present, the ad hoc network data link system is mainly divided into two types: one is a central star ad hoc network data link, a central node and multiple sub-node star-shaped networking, sub-nodes can transfer data through the central node, the group The network mode has strong real-time characteristics, but its ability to circumvent obstacles is weak, and its anti-damage performance is poor. After the central node is damaged, the relay function cannot be realized; the other is the non-central MESH multi-hop ad hoc network data link, which supports any node at any time. Move, join, exit, this networking mode has the characteristics of strong anti-damage and arbitrary relay, but the real-time performance is not strong. At the same time, the data link o...
