摘要
为解决公路隧道节能低碳、减少电力资源浪费的问题,针对公路隧道典型场景,以圭噶拉隧道为依托工程,设计了基于LoRa物联网的公路隧道按需照明控制系统。通过对物联网主流通信技术的分析比选,选择了适用于隧道典型场景的低功耗广域物联网技术,并以该技术为基础搭建了按需照明的调光系统。系统通过现场布设的各类传感器采集隧道洞外实时亮度、灯具亮度、交通量等数据,通过LoRa物联网将采集数据上传至主控器,主控器结合照明设计细则的亮度计算方法实时控制隧道内照明亮度,实现精细平滑调光。该系统还增加了车辆感应联动设施,通过检测车辆信息实现车来灯亮、车走灯熄的功能,最大程度地实现节能减排的目标。
In order to solve the energy-saving and low-carbon operation of highway tunnels and reduce the waste of power resources, for the typical scenes of highway tunnels, relying on the Guigala Tunnel, a road tunnel on-demand lighting control system based on LoRa Internet of Things is designed. Through the analysis and comparison of the mainstream communication technologies of the Internet of Things, a low-power wide-area Internet of Things technology suitable for typical tunnel scenarios is selected, and an on-demand lighting dimming system is built on the basis of this technology. The system collects real-time brightness,lamp brightness,traffic and other data outside the tunnel through various sensors deployed on site,and uploads the collected data to the main controller through the LoRa Internet of Things.The main controller combines the brightness calculation method of the lighting design rules to control the tunnel in real time Illumination brightness,realize fine and smooth dimming.The system also adds vehicle induction linkage facilities,which can realize the functions of turning on and off lights by detecting vehicle information,so as to achieve the goal of energy saving and emission reduction to the greatest extent.
