机车新型闪烁灯光示警系统的性能实验研究

Experimental Study on the Performance of New Locomotive Flash Light Alerting System

光信号示警受自然环境、气候、地段等的影响较小,尤其是在夜晚,示警效果高于声信号.新型闪烁示警灯光系统由头灯、一对具有闪烁功能的辅助照明灯组成“三角形”示警形状,并确定了灯碗散角、安装高度和间距等参数.通过实验,对灯光系统的性能进行研究,包括有效性验证、闪烁对司机眼疲劳的影响.结果表明,新型闪烁示警灯光系统的性能良好,兼顾了照明和示警的双重要求.

The Light signal is disturbed slightly by environment, climate and terrain, and is more effective than sound signal especially at night. The new locomotive flash light alerting system is made up of one headlight and a pair of auxiliary lights to form a right triangle. The auxiliary lights have the function to flash. The parameters including light beam width, the height above rail and the space of two lights have been determined. By experimental method, efficiency and the influence on drivers＇ sight tiredness to the light system have been studied. The light alerting system operates well, and meets the requirement of both illumination and alerting system.
