电机车微机数字控制制动系统

The Digital Control Braking System with a Microcomputer for Electrical Locomotive

分析了电机车制动时的运动学状况和电气制动及机械制动的特点,介绍了电机车微机数字控制制动系统的组成原理、电子电路的功能作用及控制逻辑,用控制逻辑取代了原电气控制回路中的"硬触点",减少了系统的故障源。具有一定的应用前景。

This paper analyzes the kinematics condition of electric locomotive braking and characteristics of electrical and mechanical braking. And it also introduces the composition principle, circuit function and control logic of the digital control braking system with a rnicrocornputer for electrical locomotive. Using control logic to replace the ＂hard contacts＂ for origihal electrical control circuit, the source of system failure is decreased. This system has a good application prospects.
