基于Android手机的多轴飞行器姿态控制系统 摘 要 随着Android开发技术的日趋成熟，基于Android操作系统的手机使用也越来越广泛，从而Android手机的音频接口技术的发展也引起了软件开发人员的广泛关注，可以利用音频接口进行相关的控制。 音频接口通常与前置麦克、线路输入和其他一系列的输入设备配合使用。在深入理解Android开发技术和音频接口后，构建了一个小型控制系统。该系统中通过Android平台播放纯音文件，纯音文件播放使得音频接口输出正弦波信号，并通过Android端的程序控制信号的幅度和频率。Android端通过音频线与ARM开发板连接，ARM开发板将接收的信号转换为遥控器所需的模拟信号，从而控制遥控器发出无线电波控制多轴飞行器的姿态。Android端的音频接口输出四路信号，左、右两个声道的幅度和频率信号分别对应多轴飞行器的俯仰，横滚，偏航和油门四个姿态。 该设计最终实现了将Android平台输出的音频信号转换为四路的数字信号，还未能在实体的多轴飞行器上进行测试。Android；音频；单片机 The Multirotor Attitude Control System Based on Android Abstract With the maturing of Android development technology, based on the Android operating system is becoming more and more widely used. so the Android mobile phone audio interface technology development also caused wide attention of software developers, can use to control audio interface. Audio interface and pre - mike usually, line input and a host of other input devices.In the deep understanding of the Android development technology and audio interface. I built a small control system. The system through the Android platform in the play pure tone files, pure tone file broadcast audio interface output sine wave signal, and through to the Android program control signal amplitude and frequency.Android through audio line connected to the ARM development board, ARM development board will receive signals into analog signals required for remote control, remote control to control a radio control multi-axis vehicle attitude. Androids audio output interface four-way signal, the amplitude and frequency of the left and right two channel signals respectively corresponding to the pitch of multi-axle vehicle roll and yaw and the throttle four gesture. Finally achieved the design of the Android platform of the output audio signal can be converted into four digital signal of the road. But not on the entity of multi-axle vehicle test.
