摘 要 作为自动化领域的热点之一，现场总线己成为自动化系统与分散的现场设备间信息交换的主要技术。PROFIBUS是国际上应用十分广泛的工业过程现场总线，主要应用于加工自动化、过程自动化、楼宇自动化等领域。 文章从结合所研究的水厂的实际需要出发，将先进的现场总线技术、以太网技术与传统的机械电气技术相结合，并应用到水厂控制系统的实际设计过程中。在电气控制系统的设计过程中，采用了上位机加下位机的设计模式，组建了远程集中控制与现地控制相结合的控制网络。上位机选用功能强大的工控组态软件——组态王和操作方便灵活的触摸屏。下位机则采用可靠性高的可编程控制器和先进的PROFIBUS现场总线完成对现场设备的控制。 关键词：可编程控制器，现场总线，PROFIBUS-DP， 监控系统 The Control System Based on Fieldbus Abstract Nowadays, the technology of Fieldbus has become the hotspot in the research field of automation and become the main method of communication and exchange of information in the DCS systems. And the Profibus is a kind of Fieldbus broadly used in many situations of process control of industry such as automation of processing, automation of machining and automation of building. According to the actuality of the studied water station, the thesis combine the advanced Fieldbus technique, Ethernet and the traditional machine and electric technique together, and use them to design the supervise controlling system of the water station. During the designing of the electricity control system, the thesis used the mode that made up of monitor system and control system, formatted a network that is combined by far concentrates control system and nearly control system. The monitor system chooses the functional monitoring software—the king monitor and the man-machine interface, which operated conveniently. And the control system chooses dependably programmable logic controller and advance Profibus Fieldbus to completely control the spot equipments.
