摘　　要：针对多旋翼无人机在飞行操作中常受气象条件、误操作等多种影响导致无人机坠机问题,本文设计一款基于STC89C52RC单片机与nRF24L01+无线收发的失控一键开伞装置。当机体发生意外坠机时,地面操作人员按下手中开伞按键,在3 s内有效遥控打开降落伞并平稳落地,开伞最低高度为4 m,遥控距离最远可达750 m。该系统具有结构简单、响应迅速、安全性高等优点,对降低机体损坏、保护人身安全具有重要意义。In order to solve the problem that the multi-rotor UAV is often affected by meteorological conditions,misoperation and other factors in flight operation,resulting in the UAV crash,this paper designs a runaway one-button umbrella opening device based on STC89C52RC single-chip microcomputer and nRF24L01+wireless transceiver.When the plane crashes unexpectedly,the ground operator will press the button to open the parachute,and the parachute will be launched by remote control within 3 seconds.The lowest height of the parachute is 4 meters,and the remote control distance can reach 750 meters.The system has the advantages of simple structure,rapid response and high safety,which is of great significance to reduce the damage of the body and protect the safety of human beings.
