摘要
为了防止电机车制动过程中发生滑移,研制了一种基于单片机控制的电机车防滑控制系统。该系统采用速度传感器采集车轮转速,计算车身速度、滑移率和减速度等控制参数,当控制参数超过逻辑门限值时,向防滑排风阀发出控制指令,通过防滑排风阀调整机车制动力,从而使车轮和轨道之间的黏着系数保持在最大值,最大程度上利用摩擦力进行制动,减少制动距离,提高电机车安全性。
In order to prevent the sliding phenomenon in the braking process of electric locomotive, an anti-skid control system of electric locomotive based on single chip microcomputer is developed. The speed sensor is used to collect the wheel speed, calculate the body speed, slip rate, deceleration and other control parameters. When the control parameters exceed the logical threshold value, the control command is sent to the anti-skid exhaust valve, and the locomotive braking force is adjusted through the anti-skid exhaust valve, so as to keep the adhesion coefficient between the wheel and the track at the maximum value, and brake to the maximum extent by using friction, Reduce the braking distance and improve the safety of electric locomotive.
