Abstract

The invention provides an auto-management data link of micro unmanned aerial vehicles, which comprises a physical medium which is 2.4 to 2.483GHz microwaves, a link protocol which is ZigBee protocol is an international standard IEEE802.15.4-based wireless network protocol, and equipment formed by connecting a micro unmanned aerial vehicle model with a wireless module and an antenna, which are fixedly arranged in the unmanned aerial vehicle model, through a serial port RS-232. The wireless module consists of a ZigBee coordinator and a ZigBee router and adopts a half duplex communication mode; a data link network topology is a tree topology; and data link simulation software is the 14.5 edition of OPNET network simulation software. The data link allows the transmission speed of the unmannedaerial vehicles to reach 250kbps; the channel utilization rate can reach 90 percent; the packet transfer delay is 0.4s; and the throughput of the data link is 63kbps.

Description

technical field [0001] The invention relates to a data link for the autonomous management of a micro unmanned aerial vehicle group, and belongs to the technical field of wireless communication. Background technique [0002] With the advancement of aviation technology and the traction of military struggle requirements, UAV (Unmanned Aerial Vehicle, referred to as UAV) will play an increasingly important role as one of the members of multi-aircraft formation cooperative operations. At present, most of the domestic and foreign research on multi-UAV formation cooperative operations stays in theoretical research and simulation of control algorithms and decision-making methods. [0003] The research of the "UAV SWARM Health Management Project" project team of the Massachusetts Institute of Technology proposed a practical UAV group health management system. [0004] This project proposes a unique multi-UAV test system based on indoor and outdoor test flights in a long-term control...
