基于时间片的多单片机通信方法

A Communication Method for Multi Single chip Computer System Based on Time Segment

介绍由６０余个单片机组成的电化教学系统中多机通信的软硬件实现方法，重点阐述时间同步技巧和减少通信开销的协议安排，讨论了差错处理技术。给出的软硬件方法亦适用于工业控制中基于单片机的多机系统。

A software and hardware implement method for communication in an electronic teaching system with more than sixty shigle-chip computers is introduced. A time-synchronization technique and a decreasing communication-consuming agreement are diseussed stressfully in this paper, as well as error processing technique. The method also is suitable to applications in multi-level systems based on single-chip computer in industrial control.
