【摘要】：伴随我国交通建设的快速发展和公路隧道的日趋增多,公路隧道照明引起的巨大的能源消耗已被重点讨论。国内隧道大都存在着能源消耗和资源浪费现象,许多公路隧道的供电光源控制方法比较单一,不能根据实时的环境条件进行调光,节能效果不明显。隧道照明调光优化技术的研究,不仅保证了驾驶员进出隧道以及在隧道内行驶的安全性,同时避免了不必要的能源消耗。本文提出了选用PLC为控制核心,实现根据隧道内外部的实际环境条件实时优化调节隧道各区段照明的设计方法。依据最新颁布的《公路隧道照明设计细则》(JTG/T D70/2-01-2014),设计整个系统的硬件框架,之后给出一套以PLC为处理核心,以视频车辆检测器和洞外亮度检测器、PLC相关数据接收模块组成的硬件框架,对硬件各部分的主要特点和功能做了介绍,同时介绍了相关的硬件地址分配和接口连接。根据需求和硬件框架设计,对PLC、各检测器、现场总线等各部分的通信和数据处理部分进行了软件程序设计。并且给出了一套依据实际情况的隧道最优化照明节能调光优化模型,利用模型设计出一套最优化节能控制算法,算法以以隧道内部的实际照明总功率最小为目标,实现照明控制能够依据隧道洞外的实际亮度和隧道内部实际车辆运行情况来进行实时的照明优化,求出符合实时照明需求的最节能的调光占空比。最后在实验条件下对各检测器的通信及数据检测进行了现场验证,并且结合温州的江北岭隧道为例,仿真模拟整个系统的调光过程及及相应的调光占空比的优化程度,对系统的节能效益进行了估算。
[Abstract]:With the rapid development of traffic construction and the increasing number of highway tunnels in China, the huge energy consumption caused by highway tunnel lighting has been discussed. Most domestic tunnels have the phenomenon of energy consumption and resource waste. The control method of power supply light source in many highway tunnels is relatively simple and can not be adjusted according to the real time environmental conditions, so the effect of energy saving is not obvious. It not only ensures the safety of the driver in and out of the tunnel, but also avoids unnecessary energy consumption. In this paper, PLC is used as the control core. The design method of realtime optimizing and adjusting the lighting of each section of the tunnel according to the actual environmental conditions inside and outside the tunnel is realized. According to the newly promulgated detailed rules for Lighting Design of Highway Tunnel, the hardware frame of the whole system is designed according to JTG / T D70 / 2-01-2014. Then a set of hardware frame which is composed of video vehicle detector and external luminance detector is presented. The main features and functions of each part of the hardware are introduced. At the same time, the hardware address assignment and interface connection are introduced. The communication and data processing part of the field bus and other parts are programmed, and a set of optimization model of energy saving dimming of tunnel lighting is given according to the actual situation, and a set of optimal energy saving control algorithm is designed by using the model. With the aim of minimizing the actual total power of lighting inside the tunnel, the algorithm can realize the lighting control based on the actual luminance outside the tunnel and the actual operation of the vehicle inside the tunnel to optimize the lighting in real time. The most energy saving dimming duty cycle which meets the real-time lighting requirement is obtained. Finally, the communication and data detection of the detectors are verified in the field under the experimental conditions, and the Jiangbei Ridge Tunnel in Wenzhou is taken as an example. The whole system dimming process and the optimized degree of dimming duty cycle are simulated, and the energy saving benefit of the system is estimated.
