【正文】 方式的諸多弊端，由于變頻調(diào)速技術(shù)的發(fā)展， PLC 技術(shù)的廣泛應(yīng)用，工業(yè)控制技術(shù)的成熟及完善，可以很方便的組成恒壓供水系統(tǒng)，這樣不僅可以擴大水泵的高效運行，提高效率，節(jié)約能源，提高供水服務(wù)質(zhì)量，還可為安全高效生產(chǎn)提供一定的保障。然而這些辦法或自動化程度低，能量損耗大，壓力變化 大，或因為維護工作量大，水質(zhì)容易受污染而被逐步淘汰。然而，長期以來，我國用水行業(yè)的技術(shù)水平相對比較落后，自動化程度低，由于用戶用水的不穩(wěn)定性，經(jīng)常導(dǎo)致用水高峰期水壓較低，供水量低于需求量，特別是高層用戶經(jīng)常出現(xiàn)水壓太低而無法用水的狀況。近年來，能源緊張不時影響到工業(yè)生產(chǎn)及人民生活。 constant pressure water supply。s 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 people39。 關(guān)鍵字 ： WinCC；恒壓供水；監(jiān)控。組態(tài)畫面直觀，可以顯示官網(wǎng)水壓及水泵的運行狀態(tài)。因此我們就需要不斷的改進供水方式，達到節(jié)約的目的。高層供水的要求更加苛刻，采用水塔供水已經(jīng)不可能實現(xiàn)或附加費用會更高。人們對水的供應(yīng)的要求不斷提高。 摘要 ： 水對國民生產(chǎn)和生活地位是獨一無二的，并且隨著人們生活水平的不斷提高和科學(xué)技術(shù)的不斷發(fā)展。尤其是隨著生產(chǎn)效率的不斷提高。尤其是最原始的水塔供應(yīng)方式已經(jīng)遠遠不能滿足人們的需求。并且傳統(tǒng)供水系統(tǒng)以及一些不合理的供水方式也已經(jīng)不再適應(yīng)現(xiàn)在對降低能耗減少資源浪費的需求。 本設(shè)計中以 WinCC 監(jiān)測為核心，監(jiān)控系統(tǒng)和現(xiàn)場操作箱可以實現(xiàn)兩地控制，可以進行手自動切換，本地 與遠程，變頻與工頻切換。 本設(shè)計中應(yīng)用了 WinCC 監(jiān)控軟件，使用編程組態(tài)技術(shù)實現(xiàn)了基于 PLC 和變頻器控制的恒壓供水系統(tǒng)，具有高效節(jié)能、自動可靠、維護簡單、管理方便的優(yōu)點。 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 people39。s 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。 monitoring and controlling. 目錄 0 目錄 第 1章 緒論 ..........................................................................................................................1 選題的目的與意義 .....................................................................................................1 WinCC國內(nèi)外的研究現(xiàn)狀及發(fā)展趨勢 ..........................................................................1 課題主要研究內(nèi)容 .....................................................................................................2 第 2章 WinCC組態(tài)軟件 ...........................................................................................................3 ...................................................................................................3 WinCC 組態(tài)軟件的功能和特點 .....................................................................................4 WinCC組態(tài)軟件的功能 .....................................................................................4 WinCC組態(tài)軟件的特點 .....................................................................................4 第 3章 變頻恒壓供水系統(tǒng)簡述 ..............................................................................................6 ............................................................................................6 ............................................................................................6 ......................................................................................................8 ...................................................................................................8 第 4章 恒壓供水系統(tǒng)中 WinCC的應(yīng)用 ................................................................................... 10 恒壓供水系統(tǒng)中 WinCC界面的設(shè)計 ........................................................................... 10 ................................................................................................. 10 ................................................................................................. 13 ..................................................................... 16 WinCC 的組態(tài)變量及通訊 .......................................................................................... 18 WinCC的變量管理器 .............................
