在由PC 机和多台单片机构成的多机控制系统中,PC 机与多台单片机的通信接口设计是实现多

机系统功能的关键。介绍了一种基于PC 总线的PC 机与多台单片机并行通信接口设计方法,并将其应用

到交接箱远程监控管理系统中,取得了满意的结果。-In the multi2computer control system which comprises a PC and single2chip microcomputers , it is quite important to design

the interface for communicating among them in order to implement the systemfunction. In the paper , a kind of paralleled interface for

communicating based on PC bus is proposed. Good results are also obtained when it is used in the Surveillance system for distribution

boxes.
