摘要
煤矿井下通信环境复杂多变,现有的煤矿井下短距离无线通信技术在煤矿井下泛在覆盖、布设成本、电磁干扰等方面存在诸多不足。对可见光通信理论进行研究,以煤矿物联网为基础,构建了基于可见光通信的全IP煤矿井下通信系统,实现照明和通信的融合,可有效解决目前煤矿井下通信网络末端接入问题和目标精准定位问题。
Thecommunication environment to underground coal mine is complex and changeable.The existing short-range wireless communication technology have a few shortcomings,such as ubiquity and full-cover, the cost of group networks,electromagnetic interference. The theory of visible light communication is conducted. Based on mine internet of thing as study object, the overall structure of visible light communication in underground coal mine is introduced. On the basis of achieving lighting, the type of visible light communication can be used for datacommunication. Moreover, it effectively solve terminal access problemofthe coal mine communication network and target accurate positioning.
