用单片微机构成的总线型通信网络

The Bus Type Communication Network Consists of Single--Chip Computer

本文分析讨论了由单片微机构成的总线型局部通信网络,它在工业控制中有实用价值。文中分析了单总线、双总线、四总线及通信板结构,提供了接口标准及相应的软硬件。给出了主从式(轮询式)与竞争式CSMA传输控制方法。

This paper discusses the bus type lo- cal area communication network consists of sing- chip computer. It'spractical for industrialk control system. The paper analyses the structures of 1 line, 2-line, 4-line and communication board. It provides CSMA transmission control methods of roll -call and competion styles. It of fers the interface standard and relevant software and hardware.
