　　根據(jù)本公司無負壓管網(wǎng)增壓設(shè)備的特點，采用西門子 S7-200 SMART、SMART LINE 和 V20 變頻器的全套解決方案。文中對設(shè)備的工藝流程進行了分析，使用一控二的方式達到了良好的控制效果，V20 變頻器通過 Modbus 與 S7-200 SMART 進行通訊，驅(qū)動無負壓管網(wǎng)增壓設(shè)備，保證了用戶對恒壓管網(wǎng)供水的要求。在軟件方面采用了 S7-200 SMART PID 控制方式，實現(xiàn)了對無負壓管網(wǎng)增壓設(shè)備的完美控制。
　　關(guān)鍵詞：S7-200 SMART，SMART LINE，V20，無負壓管網(wǎng)增壓設(shè)備
　　1. 項目簡介
　　隨著我國物質(zhì)文明生活水平的提高，高層建筑越來越多，自來水管網(wǎng)壓力出現(xiàn)不足，很多城市普遍存在著用水高峰期上不去水的現(xiàn)象。由此引發(fā)生活、辦公用水難的問題。無負壓管網(wǎng)增壓設(shè)備可直接與自來水管網(wǎng)串接而不產(chǎn)生負壓，能夠安全、衛(wèi)生的向用戶供水。該設(shè)備充分利用了市政自來水管網(wǎng)的原有壓力，在原有壓力的基礎(chǔ)上實現(xiàn)壓力疊加，差多少，補多少，使二次加壓設(shè)備的選型減小，節(jié)省投資，同時在使用過程中也可節(jié)能很大一筆費用，是目前最先進最新型的二次供水方式。
　　該設(shè)備采用 SIMATIC S7-200 SMART + SMART LINE + V20 變頻器。優(yōu)良的工藝造就了高質(zhì)量的產(chǎn)品，強大的技術(shù)支持保證了產(chǎn)品的高性能。SIMATIC S7-200 SMART 與 SMART LINE 上添加的以太網(wǎng)口，方便了調(diào)試程序，不用頻繁的插拔電纜，節(jié)省了下載程序的時間。V20 變頻器的宏指令調(diào)用功能，可快速實現(xiàn)參數(shù)設(shè)置。V20 變頻器的小體積與上進下出的接線方式，節(jié)省了所占用的空間，便捷的接線方式，強大的功能，簡潔的操作方式，體現(xiàn)了基本型變頻器的發(fā)展趨勢。
　設(shè)備選型為一控二。自動運行時 SIMATIC S7-200 SMART 驅(qū)動 V20 變頻器。通過變頻器拖動一臺泵升速，一臺泵運行到某個頻率能夠達到目標壓力，則單臺泵進行恒壓供水。如果單臺泵運行到 50Hz，經(jīng)過延時進行切換，一臺工頻、一臺變頻運行，目標壓力為用戶設(shè)定壓力。通過觸摸屏可以查詢以及更改參數(shù)?？梢圆樵兡骋粫r間段的故障以及故障時間。觸摸屏還設(shè)計了手動控制系統(tǒng)的啟停。
　　3、 方案確定
　　由于該無負壓供水設(shè)備系統(tǒng)屬于成熟機的升級，客戶比較傾向于性價比高的產(chǎn)品。SIMATIC S7-200 SMART、SMART LINE、V20 作為西門子新一代研產(chǎn)品具有良好的性價比。SIMATIC S7-200 SMART、SMART700IE 本身具有集成的以太網(wǎng)口，既方便了技術(shù)人員的調(diào)試，又方便了設(shè)備連接到工廠的網(wǎng)絡(luò)上。SIMATIC S7-200 SMART 還有可擴展的 RS485 接口，方便了現(xiàn)場通訊口使用。
　　a)、設(shè)備接通電源，SIMATIC S7-200 SMART 電源信號燈亮，SMART LINE 處于待機工作模式，系統(tǒng)通過 SA1 分為手動與自動模式。
　　b)、SA1 轉(zhuǎn)換打到自動模式：手動模式是操作人員就地控制每臺水泵的啟停。手動運行可選擇為手動變頻或者手動工頻。手動變頻運行的時，只能運行一臺水泵，需要操作人員通過電位器控制頻率的升降。
　　c)、SA1 轉(zhuǎn)換打到自動模式：自動模式又分為屏手動與屏自動。屏手動是操作人員通過 SMART LINE 控制相對應(yīng)的每臺泵的輸出。屏自動控制需要操作人員把相關(guān)的參數(shù)設(shè)置完全,系統(tǒng)會判斷當前的實際數(shù)值與操作員設(shè)置的數(shù)值進行比較，判斷管網(wǎng)壓力是小于設(shè)定壓力還是高于設(shè)定壓力。
