【摘要】：高速公路车速快,交通量大,高速公路隧道的照明标准要求高、隧道照明功率大。高亮度长时间照明会导致灯具损坏多,更换频繁,因而隧道照明优化设计显得更为重要。 本文依据国家关于隧道照明的需求的相关规范,结合环境亮度、车速和交通量是隧道照明亮度的决定要素,以及复旦大学电光源研究所提出的中间视觉和重庆交科所提出的等效亮度等照明理论,利用新型LED灯具具有无级调光的特点,通过视频车检器来检测车辆的存在、车速和交通量,光照度传感器检测隧道洞内外环境亮度,采用PLC为控制单元,设计了一种“有车灯亮、无车灯暗”,同时亮灯时根据隧道洞口的环境亮度自适应无级调整洞内灯亮度的新型隧道照明方案,成功应用于黄塔桃高速公路的管铺街1号隧道。 本文主要工作与研究内容为：1)采用光照度传感器获取环境光的照度,经过实验室和隧道现场的多次实验,实现了LED灯具0-5V的模拟电压控制信号与灯具光通亮的线性匹配。其中LED灯单个颗粒的光效,灯具恒流源的稳定,以及两者性能的一致性是调控灯具实现的关键；2)通过视频车检器与隧道原有的其他微波或线圈检测器配合使用,提高了恶劣天气和傍晚时的检测准确率；3)采用PLC控制器作为整个系统的核心控制单元,实现了有车来时根据环境亮度、车速、交通量的变化,隧道洞内的照度也能够实时跟随变化的效果。实时变化的照度符合当时车辆的安全照度要求,无车时洞内照度维持在最低基本照度的要求。与原高压钠灯照明相比节能50%。 本文所设计的智能隧道照明系统优化了设备配置、节约了照明费用。本系统通过适当的车检器位置调整,也适用于其他照明灯具。随着LED灯具无线调控技术的发展,建设成本和调控的性能将进一步提高,因而具有广阔的推广前景。
[Abstract]:The speed of highway is fast, the traffic volume is large, the lighting standard of highway tunnel is high, and the power of tunnel lighting is large. High brightness and long time lighting will lead to more damage and frequent replacement of lamps, so it is more important to optimize the lighting design of tunnel. In this paper, according to the relevant national regulations on tunnel lighting requirements, combined with environmental brightness, speed and traffic volume are the determining factors of tunnel lighting luminance. And the lighting theory of intermediate vision proposed by the Institute of Electric Light Source of Fudan University and equivalent brightness and other theories put forward by Chongqing Jiaotong University. The new LED lamps have the characteristics of stepless dimming, and the existence of vehicles is detected by video vehicle detector. The vehicle speed, traffic volume and light intensity sensor are used to detect the environmental brightness inside and outside the tunnel. The PLC is used as the control unit to design a kind of "there is a car light on, no car light is dark". At the same time, a new tunnel lighting scheme, which adaptively adjusts the light intensity in the tunnel according to the environmental brightness of the tunnel entrance, is successfully applied to the No. 1 Guanpu Street Tunnel of Huangtadao Expressway. The main work and research contents of this paper are as follows: 1) the illumination of ambient light is obtained by using light intensity sensor, and many experiments are carried out in laboratory and tunnel field. The linear matching between the analog voltage control signal of LED lamp and the luminaire brightness is realized. Among them, the light efficiency of single particle of LED lamp, the stability of lamp constant current source, and the consistency of their performance are the key to realize the regulation and control of lamps and lanterns. 2) the video vehicle detector is combined with other microwave or coil detectors in the tunnel to improve the detection accuracy in bad weather and in the evening; 3) the PLC controller is adopted as the core control unit of the whole system, and the effect of following the change of illumination in tunnel can be realized according to the change of environment brightness, speed and traffic volume when there is a vehicle coming. The change of illumination in real time accords with the requirement of the safety illumination of the vehicle at that time, and the illumination in the tunnel is kept at the minimum basic illumination when there is no vehicle. Compared with the original high pressure sodium lamp lighting energy saving 50. The intelligent tunnel lighting system designed in this paper optimizes the equipment configuration and saves the lighting cost. This system is suitable for other lighting lamps by adjusting the position of vehicle detector. With the development of wireless control technology of LED lamps, construction cost and regulation performance will be further improved, so it has a broad prospect of promotion.
