分布式多串口步进电机控制的设计与实现

Design and Implementation of Distributed and Multi-Serial-Port Control for Stepper Motor

设计了一种基于串口扩展卡的分布式步进电机控制系统。采用串口扩展卡扩展RS-232串口数,每个串口对应一个单片机。计算机通过选择串口的方式与单片机进行通信,进而控制单个步进电机。整个系统易于扩展。重点介绍了计算机与单片机之间的控制协议及系统软硬件的实现。

A distributed stepper motor control system based on serial-port extender card is designed. Through the serial-port extender card, computer can choose one RS-232 serial-port to build one communication channel to microcontroller, then control one stepper motor. This system is easy to be extended, The controlling protocol between computer and microcontroller and the implementation of system software and hardware are introduced mainly.
