摘要
针对基于ISA总线的分布式测控系统已不适合当前PC机的发展方向,提出了一种在Windows环境下PC机与中间控制器串行通信的实现方法,研制了基于AT89C51串行通信的位置测量与电机控制系统,实现了PC机与多台单片机的实时通信,实验证明该方法可保证通信的可靠性和效率。
A new way of serial communication between a PC and a middle controller in Windows is proposed for measurement and control of a distributed ISA_bus system. A position measuring and motor control system is designed in this way to realize the real time communication between a PC and several SCMs. The reliability and efficiency of commuication achieved in this way has been proved through experiments.
