本文介绍了铁路驼峰自动化的车辆速度控制系统的方案概要及特点.提出用数理统计方法,寻找车辆走行阻力在减速器工作前后的变化规律以及用回归线法预计车辆在编组线上的走行阻力.该系统在北京丰西编组站进行了运行试验,取得了预期的效果,实践证明它是一种简单、经济、安全、可靠的溜放速度自动化制式.
This paper introduces the outline and characteristics of the program of automatic speed control system of railway humps.This paper presents a mathematical statistics method to find the variation of vehicle running resistance before and after the reducer work and the regression line method to predict the running resistance of the vehicle on the assembly line. The system was tested at Fengxian marshalling yard in Beijing and achieved the expected results. Practice has proved that it is a simple, economical, safe and reliable automated system for the speed of sliding and discharging.
