摘要
LED可见光通信技术通信速率高、绿色安全,是未来通信网络的重要通信手段之一。研究了LED可见光通信网络与以太网的互融技术。通过研制光通信介质转换模块实现了信号在RJ-45网络接口(有线)和自由空间(无线)不同传输介质之间的转换。进行了可见光通信与以太网的互融网络实验,客户端可以通过白光通信手段成功接入以太网。通过自定义通信协议实现了互融网络中服务器对多个客户端以及各个客户端相互间的信息交互。
LED visible light communication technology is featured with high communication rate, green and safe, which make it being one of the important communication methods for future communication network. The fusion technology of LED visible optical communication network with ethernet is studied in this paper. The light communication media converter circuit is designed to complete the conversion of different signals between RJ-45 network interface and free space. Experiments on the fusion network between visible optical communication with ethernet are carried out. The client can successfully access the ethernet network by means of white light communication. Through the custom communication protocol, the information transmission among the server and multiple clients is realized.
