Besides , the paper analyzed the disputing system of steady high pressure water supply , and pointed out the possibility and necessity of classifying this system out from temporary high pressure and constant high pressure water supply system , and listed modes of steady high pressure water supply system 此外，对存有争议的稳高压给水系统，分析了将该系统从临时高压给水系统中单独分出的可能性和必要性，给出了稳高压给水系统的给水方式。
Appling these methods and the software to water supply system in yuci city , the result show that the short term optimization is feasible . the development of software for optimal operation of water supply system is successful and application can reach the result of saving energy 用榆次市的给水系统作为工程实例，对该市的给水系统进行短期优化调度，结果表明，榆次市优化调度结果具有明显的节能意义，说明该优化调度模型软件的开发是成功的。
On the basis of urban water demand forecasting methods " studying , and activex controls integrated , urban water demand forecasting system for shenzhen is developed by using visual basic , sql server and matlab as the developing stage . the system , which offers a simple and efficacious way to develop software , is effective in timely optimal control of water supply system , and the system is worth referring to while developing other optimal dispatching software such as water supply system 在对城市需水量预测方法研究的基础上，本文选用visualbasic 、 matlab 、 sqlserver为开发平台，结合activcx技术开发了深圳特区需水量预测系统，为实现输配水系统的实时优化调度奠定了基础，有良好的实用价值，也提供了一种简单高效的软件开发思路，对于给水系统其它优化调度软件的开发也具有很好的参考价值。
Abstract : based on a simple analysis of the methods for water supply used domestically an d abroad , this paper discusses the principle and system ' s structure of automatic water supply system by using frequency conversion speed regulation in detail . the n the system ' s advantages are discussed and some key problems that should be pay attention to in designing are presented 文摘:在简要分析国内外给水系统现状的基础上，介绍了系统的组成，提出了以变频调速为核心所构成的全自动给水系统控制方式，并以实例详细分析了该系统的组成、工作原理以及在控制与节能方面所表现出的优越性.文中根据作者的实际使用经验，简要阐述了该系统在应用中应注意的一些问题
Abstract : the authors researched existing water distribution control systems and are willing to emphasize that ( 1 ) the progress of water industry might be obstructed if the foregoing big system is still used to considerate , because the water supply system has already became a complicated engineering being , and ( 2 ) it is most important to the technical progress of water supply if more attentions have to be paid to study the complexities of the water supply engineering and the effect to it of the existing water system control 文摘:对现行给水控制进行研究，力图说明：给水系统是一个复杂的工程存在，在水工业思想已经提出的今天，再沿用以往的大系统观将有碍于水工业工程技术的进步；重视并研究给水工程的复杂性及其对现行给水工程控制模式的影响，对给水工程科技进步至关重要。
The third generation of scada , based on the technology of distributing computer net and relation data base , could realize the large - scale internet connection , which is currently applied in data collection , surveillance control and processing control in the fields of electric power system , water supply system , petroleum and chemical industry etc . the fourth generation of scada would adopt the internet technology , object oriented technology , neural network as well as java technology as its main development tendency , aiming at enlarging the integration of scada and other systems , which could finally meet the needs of business management and integrated security economic circulation 现在的基于分布式计算机网络以及关系数据库技术的能够实现大范围联网的第三代scada系统被广泛应用于电力系统、给水系统、石油、化工等领域的数据采集与监视控制以及过程控制等诸多领域。第四代scada系统的主要发展趋势是采用internet技术、面向对象技术、神经网络技术以及java技术等技术，继续扩大scada系统与其它系统的集成，综合安全经济运行以及商业化运营的需要。
