摘要
现场总线技术具有数字化、全分散性、开放性和互操作性等特点,是当今成熟可靠的自动化技术。Profibus现场总线是使用最广泛的现场总线之一,在电力、石油化工、制造业、楼宇等领域广泛应用。对于电厂来说,水处理岛是一种新型的水处理模式,简单介绍水处理岛工艺系统。针对Profibus总线控制技术在水处理岛中的应用实例,重点介绍控制系统的网络结构及硬件配置,分别介绍主机架、网络结构、通信协议、人机接口及现场总线设备,详细阐述了水处理岛总线控制系统网络的设计思路,总结了总线控制系统在水处理岛上的应用体会。
The Fieldbus technology has following characteristics： digital, distributed, open, interoperability, and is a ripe, reliable automation technology at present. The Profibus is the one of the Fieldbus widely used in power, petrochemical, manufacture industry, homebuilding supervisory control etc.. The water treatment island is a new pattern of water processing mode, its process system is introduced simply. Aimed at application example that the Profibus control system used in water treatment island; network structure and hardware configuration are mainly introduced. The main frame, network topology, communication protocol, man-machine interface and fieldbus equipments are introduced respectively. Design thinking of the water treatment island control system network topology is described in detail,and application experience is summarized.
