智能LED隧道照明控制系统的设计与开发

The Development of LED Intelligent Illumination Control System for Tunnel Lighting

以《公路隧道通风照明设计规范》为理论依据,提出了智能LED隧道照明控制系统的设计思路。通过采集洞外的亮度和驶经车辆的车流量及车速改变LED灯的驱动电流,从而实现对隧道灯的无级控制,满足人眼的特性曲线,保障驾驶员的安全。对系统的软件进行分析,将任务的各功能模块进行划分,并据此制定了中心控制器、节点控制器与监控中心之间的通信协议。设计了基于ARM的中心控制器模块以及节点控制器模块的硬件电路。最后针对系统中的不足并提出改进建议。

Based on the design standard of the ventilation and illumination of highway tunnel,a design of the intelligent illumination control system was put forward.The luminance outside the tunnel and the traffic flow and speed were collected to change the drive current of the LED,which can smooth luminance of each section to fit the curve of human eyes to make sure the safety.The system software was analyzed and functional module was described. Based on the analysis communication protocols between the center controller, the node controller and monitor center were set up.The hardware circuits of the center controller and the node controller were designed.Finally, the system deficiencies were analyzed and some suggestion were given.
