基于光纤令牌总线的分布式数据监测系统设计

Design of Distributed Data Monitoring System Based on Fiber Token Bus

针对目前分布式数据监测系统普遍存在数据传输不及时,数据传输丢包率高等问题,设计了一种基于ARCNET令牌传递协议的光纤传输总线,以此为系统的神经中枢,将物理上分散的监测点有机地联系在一起,实现相互协调和系统信息的共享,使系统中庞大繁杂的数据信息可靠而高效的传输。文中介绍了一种基于ARCNET令牌协议的光纤令牌总线的搭建方法,将其应用于分布式数据监测系统中。监测区域节点数据传回上位机显示,该系统数据传输丢包率低,数据传输稳定、可靠性高。

Distributed data for the current data transmission is not ubiquitous monitoring system in time,problems such as packet loss rate data transmission,optical fiber transmission bus is designed based on the ARCNET protocol token passing,as a central nervous system will physically discrete The monitoring points are organically connected to achieve mutual coordination and sharing of system information,so that the large and complex data information in the system can be reliably and efficiently transmitted. This article introduces a method of building a fiber optic token bus based on the ARCNET token protocol,and applies it to a distributed data monitoring system. The data of the monitoring area node is transmitted back to the host computer to show that there is no packet loss in the system data transmission,and the data transmission is stable and highly reliable.
