摘要
设计并实现了一种利用可见光通信技术的音乐播放器。系统发送端使用STM32读取音乐文件并解码,经发光二极管驱动电路发送;接收端使用透镜聚光,利用光电二极管实现光电转换,经过互阻放大和滤波电路,最终实现音乐播放。系统具有点播功能,可以实现远程无线控制。测试结果表明,信号传输距离可达5 m,音质清晰,遥控范围为10 m,能够满足设计要求。
Abstract
In this paper, we design and realize a music player based on visible light communication technology. At the transmitter side, the STM32 module reads the music files and decodes them, which are sent by LED array. At the receiver side, a lens condenses the light which carries information. A PIN photodiode converts the light into the current. After that, through a trans-impedance amplifier and a filter circuit, the music can be played by a speaker. The system has on-demand function, which can achieve remote wireless control. The test results show that the transmission distance of the signals can be up to 5 m, with clear sound. And the remote control achieves a range of 10 m, which satisfy the requirement of the design.
