总线竞争式通信的实现

Implementation of Communication Based on Race Bus

在总线结构的分布式测控系统中 ,当系统实时性要求较高、突发性较强时 ,主从通信方式往往不能适应需要 ,而需要采用竞争式通信 .讨论了在非平衡传输和平衡传输的两种典型总线上实现竞争式通信的方案 .该方法简单可行 。

In distributed measurement and control system with bus structure, master slave communication may be replaced by race communication, when real time and burst are needed. In this paper, the implementations of communication for race bus based on balance and unbalance transmition are discussed. The present method is sample and useful in some measurement systems.
