说明：  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
(Based on the ISA bus Distributed Control System is not suitable for the current development of the PC direction, a Windows PC environment with the serial communication controller middle of the method was developed based on the serial communication AT89C51 position measurement and motor control system that the PC and more single- the real-time machine communications, experiments show that this method can ensure the reliability of communications and efficiency)
