【摘要】：针对传统隧道照明系统存在的环境适应性差、能源浪费大、环境污染高、安全程度低、智能化水平低等问题,本论文在公路隧道照明领域中以“按需照明”为理念、节能环保为宗旨、新型LED照明技术为基础,建立一种新型的隧道照明节能系统运行模式和控制方法。新型的运行模式以实时的洞外亮度、交通流量、车流速度三个参数为模型输入,通过线性插值法、阶跃线性化和对数调光等数学手段来平滑曲线,从而建立节能运行模式下的亮度变化曲线模型,动态调节隧道入口段、过渡段、中间段、出口段各区段的长度和亮度,使隧道照明系统安全、高效、经济、节能。新型的隧道照明节能控制系统,以工业以太网、RS485总线、ZigBee无线技术自上而下组建通信网络,以智能控制为主、半自动控制和手动控制为辅设计隧道照明控制模式,以DALI-M协议作为隧道灯光控制协议,保证整套系统的可靠性和准确性。下位机系统采用分层模块化设计,分为隧道监控主控制器、DALI主控制器和DALI从控制器三大模块。对其中的CPU模块、电源模块、数据通信模块、DALI主从机接口模块、LED恒流驱动调光模块等关键电路设计并得以实现。上位机系统以新型运行模式为基础,连接下位机系统,实时接收并显示环境参数,动态调节隧道LED照明灯具的亮度；在图形化隧道平面图上实时显示隧道照明状态,对系统异常报警实时显示和提醒,在系统异常情况下自动切换预定义的控制模式,提高隧道管理人员的效率和系统智能化水平,实现智能的自适应隧道照明控制系统。最后,对系统的软、硬件进行调试,为验证系统的可行性在隧道沙盘模型上进行了演示,达到了预期的效果。
[Abstract]:Aiming at the problems existing in the traditional tunnel lighting system, such as poor environmental adaptability, large energy waste, high environmental pollution, low safety level and low intelligence level, this paper takes "on-demand lighting" as the concept in the field of highway tunnel lighting. Based on new LED lighting technology and energy saving and environmental protection, a new operation mode and control method of tunnel lighting energy saving system are established. Through linear interpolation, step linearization and logarithmic dimming to smooth the curve, the model of luminance change curve under the mode of energy saving operation is established, and the tunnel entrance section is dynamically adjusted, the three parameters of the vehicle flow speed are input into the model, and the linear interpolation method, step linearization and logarithmic dimming are used to smooth the curve. The length and brightness of each section of the transition section, middle section and outlet section make the tunnel lighting system safe, efficient, economical and energy-saving. Based on industrial Ethernet RS485 bus and ZigBee wireless technology, the communication network is constructed from top to bottom, with intelligent control as the main control, semi-automatic control and manual control as auxiliary design of tunnel lighting control mode, and DALI-M protocol as tunnel lighting control protocol. In order to ensure the reliability and veracity of the whole system, the lower computer system adopts hierarchical modularization design, which is divided into three modules: tunnel monitor main controller, Dali master controller and DALI slave controller. Among them, the CPU module, power module, power module, The key circuits such as LED constant current drive dimming module and so on are designed and realized in the data communication module. The upper computer system is based on the new operation mode and connects the lower computer system to receive and display the environmental parameters in real time. The luminance of tunnel LED lighting is dynamically adjusted, the tunnel lighting status is displayed in real-time on the graphical tunnel plan, the system abnormal alarm is displayed and alerted in real time, and the predefined control mode is automatically switched under the abnormal condition of the system. In order to improve the efficiency of tunnel managers and the level of system intelligence, an intelligent adaptive tunnel lighting control system is realized. Finally, the software and hardware of the system are debugged, and the feasibility of the system is demonstrated on the tunnel sand table model. The expected effect has been achieved.
