摘要
为降低隧道照明系统能耗,研究隧道灯具的最优布置方法,基于MATLAB软件编写一种包含隧道照明计算与参数优化功能的程序。照明计算程序根据输入的隧道参数与布灯参数,计算输出平均亮度、总均匀度和纵向均匀度作为照明效果评价指标,并实现路面亮度分布的可视化。选取中线布置、对称布置和交错布置3种灯具布置方式,调整灯具间距、高度、偏置距离和角度4个布灯参数。通过程序计算分别研究布设方式和灯具参数对隧道照明效果的影响。计算结果表明:1)在灯具总功率和布置间距相同的情况下,中线布置方案相较于对称布置方案的路面平均亮度提高27.63%,但总均匀度降低44.60%;2)路面平均亮度与灯具高度呈负相关,随灯具角度增大呈现“先增后减”的非线性趋势;3)以隧道灯具总能耗为评价指标,通过粒子群算法进行布灯参数的最优化计算,优化方案增大了灯具间距并降低了灯具布置高度,使得灯具总功率较原始方案降低17.88%;4)通过DIALux软件构建隧道仿真模型进行结果验证,其中平均亮度的误差为4.41%,均匀度的误差在10%的容许范围内,验证了本程序的有效性和准确性。
Efficient lamp arrangement methodologies are essential for minimizing energy consumption in tunnel lighting systems.The authors present a MATLAB-based program that integrates tunnel lighting calculations with parameter optimization.The lighting calculation program computes the average output luminance,total uniformity,and longitudinal uniformity,which serve as indicators for evaluating lighting effectiveness based on input tunnel and lighting parameters.This approach enables the visualization of road brightness distribution.Three lamp layout configurations(central,symmetrical,and staggered)are evaluated by varying four parameters:lamp spacing,installation height,offset distance,and tilt angle.The effects of the lamp arrangement methodologies and parameters on tunnel lighting effectiveness are investigated.The results reveal the following:(1)Under identical total power and spacing conditions,the central layout achieves an average luminance that is 27.63%higher than that of the symmetrical layout but also shows a 44.60%reduction in total uniformity.(2)Average luminance is inversely related to lamp installation height and exhibits a nonlinear trend,initially increasing and then decreasing with changes in the lamp tilt angle.(3)A multi-objective framework based on a particle swarm optimization algorithm is applied to minimize total energy consumption.The optimized configuration results in a 17.88%reduction in total power consumption compared to the baseline setup while maintaining compliance with lighting standards.(4)Validation through DIALux simulations confirms the program′s effectiveness,with average illuminance errors of 4.41%and uniformity errors within the acceptable 10%tolerance,thus verifying the accuracy and reliability of the proposed methodology.
