摘要
利用多目标进化算法,建立了城市隧道照明优化设计模型,并提供了城市隧道照明中的相关设计参数的理论值,既能满足保证行车安全的照明需求,又能尽量减少布灯数目实现绿色节能。首先确定了灯具间距、安装高度、安装角度以及灯具相距道路中线的侧向距离等作为基本设计参数,定量分析了相应参数对隧道照明质量的影响,并建立了隧道照明优化设计模型。其次基于建立的模型具有的多参数、非线性的特点,选用进化算法NGSAII对其进行求解,为以后的隧道照明设计灯具安装提供理论参考。
In this paper,an optimization model of urban tunnel lighting design is created,and multi-objective evolutionary algorithm are applied to this model to obtain parameters of lamps installation,which can not only meet the basic lighting requirements to guarantee traffic safety,but also can reduce the number of lamps to achieve green energy.On the one hand,variables like the distance of lamps,installation height,installation angles and the distance to centerline of the road are determined and the calculation process of corresponding parameters on the tunnel basic lighting indicators is analyzed;on the other hand,the usage of multi-objective evolutionary algorithm NSGA-II solves the problem in spite of the complexity of multi parameter and nonlinear model.And this paper provides a theoretical reference for the future design of tunnel lighting lamp installation.
