基于ZigBee无线网络的隧道LED灯控制系统

Tunnel led light control system based on ZigBee wireless networking

针对当前隧道照明控制存在的单一性突出、布线难度大,以及盲目控制隧道照明亮度给行车安全带来的隐患等问题,设计出了一种基于ZigBee无线网络技术的簇树型隧道LED灯控制系统。该系统采用嵌入式结构,采用QT进行了用户交互界面的设计;将系统控制分为3种模式:手动模式、自动模式以及定时模式,同时将隧道划分为5个路段:入口段、入口过渡段、中间段、出口过渡段以及出口段,然后根据各个路段进行分段照明控制,通过安装在各路段的环境参数采集终端定时采集各路段的车速、车流量以及洞内外亮度,进而具体制定了各路段的自动照明策略,并利用ZigBee无线网络进行组网,通过路段控制器实现了控制命令和数据的无线传输。研究结果表明,该系统组网速度快、布线少、数据传输可靠。

Aiming at the singleness of current tunnel lighting control system,routing difficulty and blinding control of the tunnel lighting brightness would bring danger for safety. A tunnel LED control system which used ZigBee wireless networking based on cluster tree structure was designed, in which the embedded structure was the core, and an user interaction interface was designed by QT. The system had three control mode which were manual mode, automatic mode and timer mode, the tunnel was divided into five sections： entrance section, entrance transition section, middle section, exit section, exit transition section. The lighting by tunnel section was controlled, to make automatic lighting rules based on vehicle speed, vehicle flow and the brightness of the tunnel which were collected in a certain time by environmental parameter collector. The ZigBee was used to communicate with tunnel section controller.The results indicate that the system is easy to make system networking,less routing and the data transmission is reliable.
