tain control device to stop working. Fountain works by pattern selection switch and singlestep/continuous switching decision. When step/continuous switch selection step, select only in accordance with figure fountain switch is set in a way, running a loop。因此PLC控制系統(tǒng)具有一定的工程應(yīng)用和推廣價值。PLC控制系統(tǒng)體積小、功能強、可靠性高,且具有較大的靈活性和可擴展性的特點。當(dāng)單步∕連續(xù)開關(guān)選擇單步時,噴泉只能按照花樣選擇開關(guān)設(shè)定的方式,運行一個循環(huán);當(dāng)單步∕連續(xù)開關(guān)選擇連續(xù)時,噴泉按照花樣選擇開關(guān)設(shè)定的方式,運行多個循環(huán),直至按下停止按鈕。按下啟動按鈕,噴泉裝置開始工作,按下停止按鈕,噴泉控制裝置停止工作。榆林學(xué)院本科畢業(yè)設(shè)計(論文)摘 要本設(shè)計基于西門子 S7200 PLC編程,設(shè)計了花樣噴泉系統(tǒng)?;訃娙刂葡到y(tǒng)的主要任務(wù)就是改變噴泉的噴水樣式,以達到有規(guī)律的改變噴泉噴水樣式的目的。噴泉工作方式由花樣選擇開關(guān)和單步∕連續(xù)開關(guān)決定。花樣循環(huán)方式選擇開關(guān)用于選擇噴泉的噴水花樣,本文設(shè)計四種噴水花樣循環(huán)。用 PLC花樣噴泉控制系統(tǒng),不但實現(xiàn)了自動轉(zhuǎn)換花樣噴泉的噴水樣式,提高了系統(tǒng)的可靠性和安全性,而且,美化了我們的生活環(huán)境,使我們的生活環(huán)境更加安逸、舒適。關(guān)鍵詞:噴泉,PLC控制,花樣噴泉系統(tǒng) ABSTRACTThis design is based on Siemens S7200 PLC programming, design patterns fountain system. Figure fountain control system39。 when step/continuous switching select continuous time, fountain in accordance with the pattern selection switch is set in a way, running several cycles, until you press the stop button. Figure cycle way selector switch is used to select a fountain of water spray pattern, this article design four spray pattern. The PLC control system volume is small, versatile, high reliability, and with greater flexibility and scalability features. The PLC figure fountain control system, not only for automated conversion figure fountain water style, improves system reliability and security, and beautified our living environment, make our life more easy, fortable environment. Thus plc control system has certain engineering application and extension value.Key words: fou
