WF-IoT融合物联网技术在铁路隧道照明中的应用研究

Research on the Application of WF-IoT Technology in Railway Tunnel Lighting

WF-IoT融合物联网技术具有自主组网及无线节点多的优点,在物联系统中应用较多。传统铁路隧道照明系统结构复杂,灯具供电、控制需要分别架设电缆,远程监控也要布设通信网络,照明模式单一,电缆消耗量大、施工周期长。为了克服传统系统不足,以含有WF-IoT协议的LED光源作为隧道照明灯具,每个灯具独立控制,由灯具作为通信节点在隧道内部构成无中心的无线物联网,通过网关与铁路专网连接实现远程监控管理。该系统在隧道内部无需设置照明控制箱、控制线路和通信线缆,不仅能够满足巡检照明的需求,也可实现预设的照明模式。基于灯具节点构建的WF-IoT无线网络还可用于隧道内部其他设备的监控。该技术为铁路隧道照明提供了一种新方案。

Converged Internet of Things(WF-IoT)technology is widely used in IoT systems with the advantages of independent networking and multiple wireless nodes.The traditional railway tunnel lighting system has a complex structure.It requires separate cables for power supply and control of luminaires.In the meantime,remote monitoring also needs deployment of communication networks.This leads to the higher cable consumption and longer construction cycle.To overcome the shortcomings of traditional system,tunnel lighting control and remote monitoring system based on Wide area Fusion Internet of Things(WF-IoT)is developed in this paper.The system adopts LED light source with WF-IoT protocol as tunnel lighting fixture.Each luminaire is controlled independently and all luminaires are used as communication nodes to form a centerless wireless Internet of Things in the tunnel.Thus,the lighting system is connected to the railway network through a gateway to achieve remote monitoring and management.The lighting control cabinets,control wires or communication cables is no longer needed in this system.It can not only meet the needs of patrol lighting,but also realize the preset of lighting modes.The WF-IoT wireless network can also be used to monitor other devices in the tunnel.We provide a new solution for railway tunnel lighting.
