基于LonWorks技术的水厂全分布管控一体化网络研究

摘要

In view of the most Waterworks use is distribution control mode based on PLC （DCS, Distributed Control System）. The purpose of this paper is to study a method to building Waterworks control network adopting Field bus technology. Here is the selection of Echelon out with LonWorks technology, used to construct the Waterworks＇ whole distribution integrative management and control network system, involve the function and setting of intelligent node, the construction of field control network and function and implementation of upper levels control system, for similar enterprise reference in design.%鉴于目前多数水厂采用的是基于PLC的集散式（DCS，Distributed Control System）控制模式。目的在于研究一种采用现场总线技术构建水厂控制网络的方法。这里选用的是Echelon公司推出的LonWorks技术，用来构建水厂全分布式管控一体化的网络体系，涉及现场智能节点的功能与设置、现场控制网络的构建和上层管控系统的功能与实现，可供同类企业设计时参考。
