Intelligent Detection Aircraft Design Based on Internet of Things

In order to overcome the problem of automatic reconnaissance, alarm and detection in unmanned area, a design method of intelligent detection aircraft is proposed in this paper. The design is based on Cortex-A8 processor as the control core, using quadcopter aircraft, equipped with sensors, cameras, WIFI module to achieve the reconnaissance function of aircraft. The system is built with BOA server and equipped with Mjpg- Streamer video streaming technology for the viewing of client device information and video. There are two data stream transmission modes: wiFi-based and 2.4g RF transmission. Data streams and video streams are transmitted via WIFI, and handheld remote controls send control commands to the aircraft via radio frequency signals. The experimental results show that the aircraft is stable in flight and can adjust its flight attitude and hover at fixed point. The transmission of data stream and video stream is stable and can be detected by ground PC, mobile phone and other equipment with good effect
