基于四旋翼飞行器的低空空域智能搜救系统设计

Design of intelligent search and rescue system based on four-rotor aircraft in low altitude airspace

传统四旋翼控制系统采用人工遥控控制,在搜救过程中牵扯人员精力太大并且实施飞行条件较高。现旨在缩短救援时间、提高操作便捷性,对四旋翼飞行器的各项性能做出了改进。整个系统采用人工控制模式与自动搜救模式相结合的方式对飞行器进行控制,同时也扩大了四旋翼飞行器在搜救过程中的使用范围。人工控制部分基于STC12C5A60S2单片机进行设计,结合指纹识别传感器、角度传感器、nRF24L01无线传输模块、QQ飞控、摄像头、12864液晶屏等元器件可完成身份认证、手势采集、无线传输、飞行姿态调整、高度调整及回传地理位置检测、环境视频监控信息等功能。自动控制部分基于STC12C5A60S2单片机,结合GPS模块、指纹识别传感器、nRF24L01模块、超声波模块、红外感应模块、QQ飞控、摄像头等。系统最终实现了低空空域自动避障,自动搜人等功能。

The traditional four-rotor control system uses manual remote control in the process of search and rescue leading to involving too much personnel energy and needing higher flying conditions.Now aiming to shorten the rescue time and improve operation convenience,the various properties of four-rotor aircraft has been made improvement.The whole system adopts manual control mode combined with independent intelligent control mode expanding the four-rotor aircraft＇s use range.Artificial control section is based on STC12C5A60S2 microcontroller to design,combined with fingerprint sensor,angle sensor,nRF24L01 wireless transmission module,QQ flight control,camera,12864 LCD screen can complete identity authentication,gesture acquisition,wireless transmission,flight attitude adjustment,the geographical position detection,environment,etc.STC12C5A60S2 based on single-chip microcomputer automatic control part,combined with GPS module,fingerprint sensors,nRF24L01 module,ultrasonic module,infrared sensor module,QQ flight control,cameras.The task of automatic obstacle avoidance and automatic search was realized correspondingly.
