一种全双工VLC无线导览系统的设计及实现

摘要

提出了一种具有无线管理功能的全双工可见光通信(VLC)导览系统,定义了系统设备间通信的指令集,使用ISIM仿真环境模拟了无线管理的动态修改过程.基于FPGA和Android4.3开发环境搭建了系统测试平台,并在导览设备上正确调用和播放了相应的视频文件,充分验证了该系统上行、下行链路的可行性.%This paper presents a full duplex visible light communication (VLC) navigation system with wireless management performance,and defines an instruction set for communication between system devices,uses the ISIM simulation environment to simulate the dynamic modification of the wireless management performance parameters.Basing on FPGA and Android4.3 development environment,the paper builts the current system test platform,and correctly plays the corresponding video files on the navigation equipment,which sufficiently verifies that up-down linker of the system is very right and effective.
