摘要
本文提出了一种用于现代工业设备控制的分布式多单片微机系统的通讯电路。它是以并行解优的仲裁方式来解决多单片机之间信息传输所存在的争用问题。文章详细地阐述了通讯电路的设计思想,并讨论了三种不同类型的通讯电路的工作原理。
This paper presents a type of communication circuit of distributed multiple Single-Chip microcomputer system which is used in morden industrial equipment control. An arbitration based on parallel priority technique is used to solve the competition of information transfer among multiple Single-Chip microcomputers. The design concept of communication circuit is described in detail, and the operating principle of three different types of communication circuit is discussed.
