　　根据本公司无负压管网增压设备的特点，采用西门子 S7-200 SMART、SMART LINE 和 V20 变频器的全套解决方案。文中对设备的工艺流程进行了分析，使用一控二的方式达到了良好的控制效果，V20 变频器通过 Modbus 与 S7-200 SMART 进行通讯，驱动无负压管网增压设备，保证了用户对恒压管网供水的要求。在软件方面采用了 S7-200 SMART PID 控制方式，实现了对无负压管网增压设备的完美控制。
　　关键词：S7-200 SMART，SMART LINE，V20，无负压管网增压设备
　　1. 项目简介
　　随着我国物质文明生活水平的提高，高层建筑越来越多，自来水管网压力出现不足，很多城市普遍存在着用水高峰期上不去水的现象。由此引发生活、办公用水难的问题。无负压管网增压设备可直接与自来水管网串接而不产生负压，能够安全、卫生的向用户供水。该设备充分利用了市政自来水管网的原有压力，在原有压力的基础上实现压力叠加，差多少，补多少，使二次加压设备的选型减小，节省投资，同时在使用过程中也可节能很大一笔费用，是目前最先进最新型的二次供水方式。
　　该设备采用 SIMATIC S7-200 SMART + SMART LINE + V20 变频器。优良的工艺造就了高质量的产品，强大的技术支持保证了产品的高性能。SIMATIC S7-200 SMART 与 SMART LINE 上添加的以太网口，方便了调试程序，不用频繁的插拔电缆，节省了下载程序的时间。V20 变频器的宏指令调用功能，可快速实现参数设置。V20 变频器的小体积与上进下出的接线方式，节省了所占用的空间，便捷的接线方式，强大的功能，简洁的操作方式，体现了基本型变频器的发展趋势。
　设备选型为一控二。自动运行时 SIMATIC S7-200 SMART 驱动 V20 变频器。通过变频器拖动一台泵升速，一台泵运行到某个频率能够达到目标压力，则单台泵进行恒压供水。如果单台泵运行到 50Hz，经过延时进行切换，一台工频、一台变频运行，目标压力为用户设定压力。通过触摸屏可以查询以及更改参数。可以查询某一时间段的故障以及故障时间。触摸屏还设计了手动控制系统的启停。
　　3、 方案确定
　　由于该无负压供水设备系统属于成熟机的升级，客户比较倾向于性价比高的产品。SIMATIC S7-200 SMART、SMART LINE、V20 作为西门子新一代研产品具有良好的性价比。SIMATIC S7-200 SMART、SMART700IE 本身具有集成的以太网口，既方便了技术人员的调试，又方便了设备连接到工厂的网络上。SIMATIC S7-200 SMART 还有可扩展的 RS485 接口，方便了现场通讯口使用。
　　a)、设备接通电源，SIMATIC S7-200 SMART 电源信号灯亮，SMART LINE 处于待机工作模式，系统通过 SA1 分为手动与自动模式。
　　b)、SA1 转换打到自动模式：手动模式是操作人员就地控制每台水泵的启停。手动运行可选择为手动变频或者手动工频。手动变频运行的时，只能运行一台水泵，需要操作人员通过电位器控制频率的升降。
　　c)、SA1 转换打到自动模式：自动模式又分为屏手动与屏自动。屏手动是操作人员通过 SMART LINE 控制相对应的每台泵的输出。屏自动控制需要操作人员把相关的参数设置完全,系统会判断当前的实际数值与操作员设置的数值进行比较，判断管网压力是小于设定压力还是高于设定压力。
