摘要

现场总线(Fieldbus)是指开放式、国际标准化、数字化、相互交换操作的双向传送、连接智能仪表和控制系统的通信网络。它作为工厂数字通信网络的基础沟通了生产过程现场及控制设备之间及其与更高控制管理层次之间的联系。它不仅是一个基层网络而且还是一种开放式、新型全分布控制系统。这是一项以智能传感、控制、计算机、数字通讯等技术为主要内容的综合技术是信息化带动工业化和工业化推动信息化的适用技术是能应用于各种计算机控制领域的工业总线因现场总线潜在着巨大的商机世界范围内的各大公司投入相当大的人力、物力、财力来进行开发研究[1]。当今现场总线技术一直是国际上各大公司激烈竞争的领域由于现场总线技术的不断创新过程控制系统由第四代的DCS发展至今的FCS(Fieldbus Control System)系统已被称为第五代过程控制系统[2]。而FCS 和DCS 的真别在于其现场总线技术。现总线技术以数字信号取代模拟信号在3C(Computer 计算机、Control 控、Commcenication 通信)技术的基础上大量现场检测与控制信息就地采集、就地处理、就地使用许多控制功能从控制室移至现场设备。由于国际上各大公司在现场总线技术这一领域的竞争仍未形成一个统一的标准目前现场总线网络互联都是遵守OSI 参考模型[3]。由于现场总线以计算机、微电子、网络通讯技术为基础这一技术正在从根本上改变控制系统的理念和方法将极大地推动整个工业领域的技术进步对工业自动化系统的影响将是积极和深远的。

Abstract

Fieldbus (Fieldbus) refers to open, international standardization, digital and mutual exchange operations two-way transmission, connecting intelligent instrument and control system of communication network. It as plant digital communication network, the basis of the production process communication between field and the control equipment with higher control management level and the contact between. It s not only a grass-roots network, but also a kind of open, new whole distribution control system. This is an intelligent sensing, control, computer, digital communication technology as the main contents of the comprehensive technology, is becoming an information based society impetus industrialization and the industrialization push the applicable technology, information can be applied to various computer control areas of industrial bus, because of fieldbus potential great opportunities, the worldwide each big companies invest considerable human, material nd financial resources to develop research [1]. Today's Fieldbus technology has been international companies competitive field, because of Fieldbus technology unceasing innovation, process Control System consists of the fourth generation since the DCS development of Fieldbus Control System (FCS) System, has been called the fifth generation process Control System [2]. But the real difference of DCS and FCS in the fieldbus technology. Now bus technology replaced with digital signal analog signals in 3C (Computer Control Control, Computer, Commcenication communication) technology, and on the basis of field test and Control information of in situ Set, in situ treatment and on-the-spot use, many control functions from the control room moved to site equipment. The big company because international in the fieldbus technology this field of competition, still not form an unified standards, currently fieldbus network interconnection abide by the OSI reference model [3].
