夜间机车驾驶环境中LCD眩光的分析与评价

Compositive Analysis and Evaluation of Glare at LCD in Locomotive's Driving Environment During Night-Time

眩光对司机室液晶显示设备的认读直接影响到人机交互的有效性和列车的行车安全.针对我国铁路干线机车夜间运行环境,对机车室内照明条件下车载液晶显示器(LCD)的眩光进行了测试,对机车夜间正常运行时车载液晶显示器上的眩光产生机理及其等级进行了综合分析,提出了机车夜间运行时室内光源及光照度布置的参考方案.

The impact of glare on readability at Liquid Crystal Displays (LCD) will directly affect the efficiency of the man-machine interaction and even the safety of a roaring train. Under the running condition of Chinese main locomotives during night_time, this paper measures the glare at LCD in a series of experiments on the indoor illumination conditions at night, and also this paper compositively analyses the mechanism and the indices of glare of the LCD installed in the current cab on the rails. In conclusion, this paper develops a reference arrangement scheme and illuminance of the door light source in the locomotive cab when the train moves at night.
