1、 1 基于单片机的步进电机运行控制系统基于单片机的步进电机运行控制系统 摘要摘要： 步进电机是一种将脉冲信号转换成直线位移或角位移的控制微 电机,其机械角位移和转速分别与输入电机绕组的脉冲个数和脉冲频 率成比例;它易于实现与计算机或其它数字元件接口，适用于数字控 制系统。通过一种设计方案，包括硬件的介绍和组建、硬件原理图和 软件流程图的设计、源程序的编写等，介绍一种基于单片机的步进电 机运行控制系统。该系统接收到液氮液面的液位信号后，与键盘、显 示系统设置的初值比较后，转化成步进电机的步进脉冲， 然后通过单 片机控制器驱动步进电机旋转，以带动丝杆传动系统，进而控制液氮 液面升降的运动。 关键词
