摘要
动车组列车司机室照明环境对于保障列车司机视觉作业有着不容忽视的作用,反射眩光是影响司机室照明质量的主要因素之一。司机室内照明灯具选用不当、不合理的照明布置方案与内饰设计方案以及不合适的司机室空间布局方案,会引起司机室内出现反射眩光,进而影响行车安全。本文采用视觉仿真方法,利用视觉仿真模拟软件平台,以视光学理论与光线追踪算法为理论基础,搭建能够模拟人眼真实视觉感受的司机室视觉仿真模型,获得照明环境下司机室反射眩光参数,通过调整司机室灯具数量、布置位置,或选择合适的灯具,有效控制司机室内眩光对司机驾驶作业的影响。
EMU driver＇s cab lighting environment has the momentous function of ensuring the visual task of the train driver.Reflected glare is one of the main factors affecting the quality of the driver ＇s cab lighting.Improper selection of lamps,inappropriate lighting and furnishing design,and inappropriate driver＇s cab spatial layout generate reflected glare and affect traffic safety.Based on the theory of optometry and ray-tracing algorithm,by using visual simulation software,the driver＇s visual simulation environment is set up to simulate the real human visual perception.By adjusting the number of lamps,lamps＇ position and the selection of appropriate lamps,the effect of the driver＇s cab reflected glare to the driver＇s operation can be effectually controlled.
