基于LonWorks水厂全分布式管控一体化网络前端智能节点的配置与实现

Configuration and implementation of front-end intelligent node to waterworks' whole distribution integrative management and control network on LonWorks

鉴于目前在水厂的自动控制中,多采用的是用PLC构成的集散式控制系统(Distributed Control System,DCS)。介绍采用现场总线技术(Fieldbus technology)构成全分布式管控一体化网络中前端智能节点的配置与实现。在此,首先介绍底层测控设备的类型与性能参数;进而介绍LonWorks智能节点的组成、性能和开发使用;最后,介绍该控制系统中前端智能节点的配置与实现。

In view of use more is a Distribution Control System （DCS） with PLC at present, in waterworks＇ automatic control system. In this paper will introduce the intelligent node configuration and realized in the whole distribution integrative management and control network constituted with Fieldbus technology （Fieldbus technology）. In this, first introduced the type and performance parameters of measurements and control equipments used for the bottom ,then introduces the composition, performance and the development of the LonWorks intelligent node. Finally, introduces the configuration and implementation of Front-end intelligent node in the control system.
