摘要
煤矿井下照明灯的泛在全覆盖特性,为可见光通信的应用提供了得天独厚的优势,利用这一优势设计了一种煤矿井下可见光通信定位系统。该系统将可见光通信、红外通信和电力线通信技术相结合,构建了适于煤矿井下应用环境的可见光通信系统,实现了煤矿井下人员定位、上行报警和下行广播预警等功能。与原有的煤矿井下通信定位系统相比,该通信系统性能稳定、抗电磁干扰、定位精度高,凸显出很好的实用价值。
The feature of ubiquity and full-cover of lighting in the coal mine, providing a unique advantage for the application of the visible light communication （VLC）, a visible light communication positioning system applied in mine is designed by taking this advantage. VLC technology, being applied in the coal mine, in comibination with infrared communication and power line communication technology, build a communication system suitable for coal mine. Besides, this technology makes personnel positioning, uplink and downlink broadcast warning alarm function in the coal mine being achieved. Compared with original coal mine underground communication positioning system, this system has stable performance, a good resistance to electromagnetic interference and high positioning accuracy, which is high practical valued.
