工业现场测控设备的数量远比现在Internet上的设备多，连接这些设备的控制网络将使得控制系统的性能大幅度提高，并将改变企业的运行管理模式。本文从当前现场控制网络中存在多种现场总线、多种系统和多种技术的现状，阐述了集成是现场控制网络发展的主题。简要介绍了对现场控制网络具有重要影响的设备互操作性技术、OPC技术、工业Ethernet技术、测控现场采用TCP/IP技术和现场设备实时管理技术。介绍了现场控制网络集成中的网络连接技术、自动化软件套件技术和基于WEB浏览器的实时信息监视技术。
The number of industrial field measurement and control equipment far more than the current Internet equipment, control equipment connected to these networks will make the control system performance greatly improved, and will change the operation and management mode of the enterprise. This article from the current field control network exists in a variety of fieldbus, a variety of systems and a variety of technologies, the status quo, described the integration is the scene control network development theme. This paper briefly introduces the equipment interoperability technology, OPC technology and industrial Ethernet technology that have important influence on the field control network. TCP / IP technology and field device real-time management technology are adopted in the monitoring and control site. The network connection technology, automation software suite technology and WEB browser based real-time information monitoring technology in field control network integration are introduced.
