摘要
提出了应用于微型飞行器中的新型无线数据传输系统。与传统的无线数据通信系统相比,其质量低、体积小、功耗低,可应用多种场合,抗干扰能力强,误码率达到10-6,传输有效半径达1.5km。通过微型飞行器三维模拟转台搭载微机电系统(MEMS)微型方位水平仪和微型无线数据传输系统组合的姿态测控系统,实现了对该无线数据传输系统的可靠性仿真测试。
A miniature wirelessdata communication system was developed for use in a micro air vehicle (MAV). This paper focuses on the attitude detector system which is small, light and accurate. The digital communication can provide better security, higher transmission rate and better quantity. Compared with traditional communication systems, this miniature wireless data communication system has better disturbance resistance and lower error probability (10-6) for distances up to 1 500 m. The communication system integrated with a miniature microelectromechanical system (MEMS) azimuthlevel detector was tested on a 3axis simulator which can simulate the real movement of an MAV. The results show that the miniature wirelessdata communication system reliably measures and transmits the attitude which can be used to control the MAV.
