Data chain networking method used for autonomous formation of unmanned aerial vehicle

Abstract

The invention discloses a data chain networking method used for autonomous formation of an unmanned aerial vehicle, and a data chain system provides information sharing with high speed and high updaterate under the high-dynamic environment. The data chain networking method comprises the following steps: designing a network plane structure of a data chain, defining information frames of nodes, carrying out initial networking and node accession, executing single-node initial networking or multi-node initial networking, and finally receiving and transmitting data after the nodes are accessed into a network. Based on common single-channel wireless data-transmission ratio stations, the invention realizes all functions of autonomous networking and information receiving and transmitting of the data chain. The networking method can enable a plurality of nodes to be accessed into the network autonomously in the motion process and finish data receiving and data transmission; the data link has better fault-tolerant capability, and the nodes can fall out autonomously and do not influence the normal operation of the network. The invention solves the node network-accession collision under the single-channel condition, improves the multi-node network rapid-accession ability and ensures that the data link can be operated stably in a short time.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a data link networking method for autonomous formation of unmanned aerial vehicles. Background technique [0002] The data link system is defined as a communication link and network that uses automated radio transceiver equipment to transmit and exchange load data information between users based on a common communication protocol. By definition, a system should consist of a communication protocol that is commonly observed between various radio transceivers and users. [0003] The formation flight of unmanned aerial vehicles shares information such as the position, attitude, and decision-making of each aircraft through the data link. Therefore, the data link system needs to complete the high-speed and high-update rate sharing of information under high dynamic conditions. Through the research and analysis of the technical status quo, the current data link ...

Problems solved by technology

[0006] 2. Insufficient node leaving and joining team management capabilities

The existing data link fails to consider the special operation mode of the network structure, so the response time of nodes leaving and entering the team is long, and it is difficult to achieve stable and reliable operation of the system

[0008] 3. Insufficient data link reliability
