【摘要】：隧道建设对于我国改善道路交通现状，实现经济建设的平稳快速发展具有重要意义。隧道智能照明控制系统作为隧道建设的关键技术环节，日益受到越来越多的关注。逐渐增多的隧道交通安全事故以及巨大的隧道照明成本要求我们设计一套安全、稳定、节能的隧道智能照明控制系统。根据以上对于隧道照明控制系统的设计要求，本文设计了一套基于Zigbee的智能LED隧道照明控制系统。通过Zigbee无线控制网络构建了一套动态调节LED灯具照明亮度的智能控制系统，采用模糊神经网络控制算法，能够根据隧道洞外亮度、车流量以及车速动态地调整隧道照明亮度，在保证安全性和稳定性的同时，大大节省了隧道的照明成本。本文首先对隧道照明控制系统的国内外研究现状进行了总结，，通过不同方案的对比分析确定了模糊神经网络的控制算法以及隧道照明系统的整体方案。然后，利用电力电子技术对隧道照明控制系统的硬件进行了相关设计。系统硬件以TI公司的Zigbee芯片CC2530为核心，主要设计了LED调光灯具模块、传感器采集模块以及协调器节点模块。模块化设计的思想被运用到本次系统的软件设计当中，基于Zstack的应用层，通过添加相关任务完成了LED调光灯具节点、传感器采集节点以及协调器节点的应用程序开发。同时，研究了Zigbee无线组网的软件协议，保证终端节点与协调器节点通信的稳定性。其次，利用了C#编程语言和SQL Server数据库进行了上位机监控软件的开发。监控软件具有用户管理、控制管理、监测管理以及数据库管理等多种功能，能够实时查看控制系统的工作状态，当系统出现故障时能够及时报警。最后，对全文进行了总结和展望。
[Abstract]:Tunnel construction is of great significance for improving the current situation of road traffic and realizing the steady and rapid development of economic construction. The intelligent lighting control system of tunnel is the key technical link of tunnel construction. The increasing number of tunnel traffic accidents and the huge tunnel lighting costs require us to design a safe, stable and energy-saving intelligent lighting control system for tunnels. According to the above design requirements for tunnel lighting control system, this paper designs an intelligent LED tunnel lighting control system based on Zigbee. Through the Zigbee wireless control network, an intelligent control system to dynamically adjust the lighting brightness of LED lamps is constructed. The fuzzy neural network control algorithm can dynamically adjust the luminance of the tunnel according to the luminance of the tunnel outside the tunnel, the traffic flow rate and the speed of the vehicle. The security and stability of the tunnel lighting can be guaranteed, and the lighting cost of the tunnel can be greatly saved at the same time. In this paper, the research status of tunnel lighting control system at home and abroad is summarized, and the control algorithm of fuzzy neural network and the overall scheme of tunnel lighting system are determined through the comparison and analysis of different schemes. Then, the hardware of tunnel lighting control system is designed by using power electronics technology. The hardware of the system is based on TI's Zigbee chip CC2530, and the module of LED dimming lamp is designed. Sensor acquisition module and coordinator node module. The idea of modular design has been applied to the software design of this system. Based on the application layer of Zstack, the application program development of LED dimming light node, sensor acquisition node and coordinator node is completed by adding related tasks. The software protocol of Zigbee wireless network is studied to ensure the stability of communication between terminal node and coordinator node. Secondly, we use C # programming language and SQL Server database to develop the monitoring software of upper computer, which has many functions, such as user management, control management, monitoring management and database management, etc. Can view the working status of the control system in real-time, and alarm in time when the system fails. Finally, the full text is summarized and prospected.
