【摘要】：自来水厂是城市的心脏，城市供水关乎着城市居民的日常生活起居。城市饮用水水质的高要求与落后的供水能力的矛盾日益尖锐，加快对老旧城镇水厂的改造升级的要求越来越紧迫。如何利用信息技术，引入现代化科技手段提升供水管理水平成为一个重要的研究课题。本课题主要研究如何利用科技手段保证安全、连续、优质供水，包括用于生产的自动控制和办公自动化。生产的自动控制主要通过软件组态技术实现对水厂的多级控制以及控制系统与办公系统的无缝连接,以构造安全、高效、节能的水厂自动化供水系统。水厂自控系统的设计采取“集中监控，分散控制”的原则，分三级组成控制网络，分别是就地控制、现场控制和中央控制。现场控制分站由分布在工艺流程的各个监控分站和相关在线检测仪表以及检测、执行设备组成。主要包括：取水泵房控制站、送水泵房控制站、加药间控制站、反冲洗泵房控制站以及中央控制室。中控室两个监控主站采用IFix组态软件，利用以太网与下面4个PLC主站通讯。PLC主站采用星状网络拓扑结构，每个主站的工业控制机监控各自站的数据，以避免故障发生时，单个主站的问题导致整个工厂产生监控盲点。通过对组态软件的技术的探讨，结合水厂自动化控制的需要，最后采用了GE智能平台(GE-IP)的iFIX解决方案。利用该方案实现了生产操作的过程可视化、数据采集和数据监控。系统能够精确地监视、控制生产过程，并优化生产设备和企业资源管理，提高应急反应能力，减少原材料消耗，提高生产率。同时，通过进一步研究iFix软件的内部架构，利用其预设的接口，将iFix组态软件应用于无缝连接水厂自动控制系统和办公自动化系统，解决了自动化系统数据安全问题，进一步优化友好操作界面，帮助员工更加高效地完成水厂控制工作。自动控制系统充分组态软件的功能特性，设计合理，实现规范。经三年多的使用，水厂自动化控制系统运行正常，提升了水厂的信息化管理水平。
[Abstract]:Waterworks is the heart of the city, urban water supply is related to the daily life of urban residents.The contradiction between the high demand of drinking water quality and the backward water supply capacity is increasingly sharp, so it is more and more urgent to speed up the renovation and upgrading of the old town water plants.How to use information technology and introduce modern scientific and technological means to improve the level of water supply management has become an important research topic.This paper mainly studies how to use scientific and technological means to ensure safe, continuous and high quality water supply, including automatic control of production and office automation.The automatic control of production mainly realizes the multilevel control of water plant and the seamless connection between control system and office system through software configuration technology, in order to construct the automatic water supply system of water plant which is safe, efficient and energy saving.The design of automatic control system of water plant adopts the principle of "centralized monitoring and decentralized control", and consists of three levels: local control, field control and central control.The field control sub-station consists of each monitoring sub-station distributed in the process flow and related online inspection instruments and inspection and execution equipment.It mainly includes: the control station of water pump house, the control station of water supply pump room, the control station of dosing room, the control station of backwash pump room and the central control room.The two main stations of the central control room adopt the IFix configuration software, and the communication between Ethernet and the following four main stations. The master station adopts the star network topology. The industrial control computer of each main station monitors the data of their respective stations, so as to avoid the malfunction.Problems with a single master station lead to monitoring blind spots throughout the plant.Based on the discussion of configuration software technology and the need of water plant automation control, the iFIX solution of GE intelligent platform (GE-IP) is adopted at last.Using this scheme, the process visualization, data acquisition and data monitoring of production operation are realized.The system can accurately monitor and control the production process, optimize the production equipment and enterprise resource management, improve the emergency response ability, reduce the consumption of raw materials, and improve productivity.At the same time, through the further study of the internal structure of iFix software, using its preset interface, the iFix configuration software is applied to seamlessly connect the automatic control system of water plant and the office automation system, which solves the data security problem of the automation system.Further optimize the friendly operation interface to help the staff to complete the water plant control more efficiently.The automatic control system has the function characteristic of configuration software, reasonable design and standard realization.After more than three years of use, the automatic control system of water plant runs normally, and improves the information management level of water plant.
