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.
