减速顶是根据对车辆溜放速度的判断来决定是否对车辆起减速作用的,但是千变万化的编组作业并不是仅仅根据车辆的溜放速度即可实现对车辆的控制的,往往还要根据车辆的重量、车辆的组合、车辆的走行特性等情况来决定是否对车辆进行减速控制。同时,编组场内布置的减速顶常常是车列从场内高速返回驼峰的障碍。为此,有必要研制一种可以按照人的要求,通过控制系统,随机地对车辆溜放速度进行控制的减速顶,即可控减速顶。
Deceleration top is based on the judgment of the speed of the vehicle to determine whether to slow down the role of the vehicle, but the ever-changing grouping operation is not just based on the speed of the vehicle can be achieved on the vehicle’s control, often based on the vehicle’s Weight, combination of vehicles, traveling characteristics of the vehicle, and the like, whether or not to decelerate the vehicle is controlled. At the same time, the decelerating roof arranged in the yard is often an obstacle for the train to return to the hump from the field at high speed. For this reason, it is necessary to develop a decelerating roof that can control the speed of vehicles to be controlled randomly by the control system according to human requirements, namely the decelerating roof.
