现场总线技术及其应用研究

中文摘要:

现场总线技术自70年代诞生至今，由于它在多方面的优越性，得到大范围的推广，导

致了自动控制领域的一场革命。本文从多个方面介绍了现场总线技术的种类、现状、应用领

域及前景。

现场总线FF（Field Bus）的概念起源于70年代，当时主要考虑将操作室的现场信号和

到控制仪器的控制信号由一组总线以数字信号形式传送，不必每个信号都用一组信号线。随

着仪表智能化和通讯数字化技术的发展，数字通信网络延伸到工业过程现场成为可能，由全

数字现场控制系统代替数字与模拟分散型控制系统已成为工业化控制系统发展的必然趋势。

现场总线已经发展成为集计算机网络、通信技术、现场控制、生产管理等内容为一体

的现场总线控制系统FCS（Field-bus Control System）。它将通信线一直延伸到生产现场生产

设备，用于过程和制造自动化的现场设备或现场仪表互连的现场通信网络，将传统的DCS

三层网络结构变成两层网络结构，降低了成本，提高了可靠性，实现了控制管理一体化的结

构体系。

English summary :

Fieldbus technology since the 70 birth date, because of its superiority in many ways to get a

wide range of promotion, led to a revolution in the field of automatic control. This article

describes several aspects of the types of field bus technology, status, applications and prospects.

Fieldbus FF (Field Bus) concept originated in the 70's, the main consideration was the

operating room on-site signals and control signals to control the instrument by a team bus to the

digital signal is transmitted, each signal having a set of signal lines are used . Intelligent

instrumentation and communication with the digital technology, digital communication network

extends to the field of industrial process possible, by the all-digital on-site instead of digital and

analog control system Distributed control system industrial control systems have become an

inevitable trend.

Fieldbus has developed into computer networks, communication technology, field control,

production management, etc. as one of the field bus control system FCS (Field-bus Control

System). Communication line will extend to the production site has been producing equipment for

process and manufacturing automation equipment or field instrument field-site communication

network interconnection, the traditional DCS network structure into a two-tier network

architecture, reduce costs, Improve the reliability, control and management to achieve the

integration of architecture.
