【摘要】：随着LED灯具技术的不断成熟,高速公路隧道LED灯具照明得到广泛应用,但是目前LED灯具照明设计依然采用高压钠灯设计方法,即采用回路开关来控制LED灯具照明亮度,没有充分发挥LED灯具连续调光特性,因此,设计和开发一套合理、有效的LED灯具控制系统很有必要,对节省隧道供配电回路线缆、降低隧道电能消耗有着重要意义。本论文首先介绍了高速公路隧道照明系统的现状,详细叙述了高压钠灯照明和LED照明的系统设计与控制,对隧道LED灯具各段照度进行了仿真,在满足设计亮度要求前提下分析得出了LED灯具的配置方案;其次分析了回路控制和高压钠灯存在二次启动时间长以及不能连续调光等问题,提出采用PWM数字信号传输控制LED灯具亮度的柔性调光控制方式;然后完成了柔性调光控制设计,提出了相对应的控制方案,加强照明跟随隧道外亮度检测器采集数据变化而变化,基本照明采用固定数值调光控制。本文以.net framework 4.0为平台、MSSQL2008为后台数据库,完成LED隧道柔性调光控制系统软件的设计开发。现场实验测试和节能评价分析结果表明,亮度、均匀度等参数符合设计规范,节电效果明显,满足高速公路隧道运营管理需求。
[Abstract]:With the development of LED lighting technology, LED lighting for highway tunnel has been widely used. However, at present, the design method of high-pressure sodium lamp is still used in the design of LED lamps, that is, the circuit switch is used to control the brightness of LED lamps. The continuous dimming characteristics of LED lamps have not been brought into full play, so it is necessary to design and develop a reasonable and effective control system for LED lamps and lanterns. It is of great significance to reduce the power consumption of tunnel. Firstly, this paper introduces the current situation of tunnel lighting system, describes the system design and control of high-pressure sodium lamp lighting and LED lighting, and simulates the illumination of each section of tunnel LED lamps. Under the premise of satisfying the design luminance requirement, the configuration scheme of LED lamps is analyzed. Secondly, the problems of loop control and high pressure sodium lamp are analyzed, such as long secondary start-up time and discontinuous dimming, etc. A flexible dimming control method of PWM digital signal transmission is proposed to control the brightness of LED lamps, and then the design of flexible dimming control is completed, and the corresponding control scheme is proposed. The enhanced illumination changes with the change of the data collected by the brightness detector outside the tunnel, and the basic lighting is controlled by fixed numerical dimming. This paper uses. Net framework 4. 0 as the platform and MSSQL2008 as the background database. The software of flexible dimming control system for LED tunnel is designed and developed. The results of field test and energy saving evaluation show that the parameters such as brightness and evenness are in accordance with the design criterion, and the effect of saving electricity is obvious, which can meet the requirements of highway tunnel operation and management.
