基于WinCC恒压变频供水系统毕业设计西安文理学院.docVIP

摘要： 水对国民生产和生活地位是独一无二的，并且随着人们生活水平的不断提高和科学技术的不断发展。尤其是随着生产效率的不断提高。人们对水的供应的要求不断提高。尤其是最原始的水塔供应方式已经远远不能满足人们的需求。高层供水的要求更加苛刻，采用水塔供水已经不可能实现或附加费用会更高。并且传统供水系统以及一些不合理的供水方式也已经不再适应现在对降低能耗减少资源浪费的需求。因此我们就需要不断的改进供水方式，达到节约的目的。 本设计中以WinCC监测为核心，监控系统和现场操作箱可以实现两地控制，可以进行手自动切换，本地与远程，变频与工频切换。组态画面直观，可以显示官网水压及水泵的运行状态。 本设计中应用了WinCC监控软件，使用编程组态技术实现了基于PLC和变频器控制的恒压供水系统，具有高效节能、自动可靠、维护简单、管理方便的优点。 关键字： WinCC；恒压供水；监控。 Abstract： Water on the national production and life status is unique, and along with the continuous development of science and technology and the continuous improvement of peoples living level. Especially with the continuous improvement of production efficiency. The demand for water supply is improving. Especially the original tower supply mode has far cannot satisfy peoples needs. High water requirements are more demanding, the water tower has not possible or additional costs will be higher. And traditional water supply system and some unreasonable water no longer has to adapt to now of decreasing energy consumption and reducing waste of resources. So we need to improve the water supply way constantly, achieve the purpose of saving. This design by WinCC monitoring as the core, the monitoring system and site operation box can achieve dual control, can carry out the automatic switchover of the hand, local and remote, frequency conversion and power switch. The configuration picture directly, can display the running state and the hydraulic pump. The design of the application of the WinCC monitoring software, programmed using configuration technology to realize the constant pressure water supply system based on PLC and inverter control, with high efficiency and energy saving, automatic, reliable, easy maintenance, convenient management advantages. Keywords: WinCC; constant pressure water supply; monitoring and controlling. 目录 第1章 绪论 1 1.1 选题的目的与意义 1 1.2 WinCC国内外的研究现状及发展趋势 1 1.3 课题主要研究内容 2 第2章 WinCC组态软件 3 2.1组态软件介绍及选择 3 2.2 WinCC组态软件的功能和特点 4 2.2.1 WinCC组态软件的功能 4 2.2.2 WinCC组态软件的
