PLC is the product of the bination of microelectronic technology and automatic control technology, and it can be influenced by puter technology and munication technology. Recent years, as the level of the industry automation increased in our country, PLC has been widely used in more and more fields. Siemens PLC of the s7300 series has been the favor of many industries, with the characters of pacted structure, strong extensible ability, and high function/price ratio. This design is going to fulfill a liquid level control system, which is stable, safe, and affordable, using s7300 as the controller. The core is CPU313C2DP of S7300 series and the auxiliary parts contain a solenoid valve, a pressure transmitter, a motor, PC, a separatedtype tank and so on. In the design, software system and hardware system can be designed pletely.During the designing process, first of all, hardwires are chosen and designed. Second, module programming can be done to get normalized data and Position Control. Third, HMI can be finished using King software, which is used to control the liquid level, adjust the top and bottom limitation parameters online, monitor measured value of the liquid level, and meet the technical needs of controlling liquid level.Key Word: S7300；Kingview；Liquid level目 錄1 引言 1 1 PLC及過程控制技術(shù)的概述及發(fā)展 1 本課題研究的內(nèi)容與目的 42 液位控制系統(tǒng)硬件設(shè)計(jì) 5 液位控制系統(tǒng)的系統(tǒng)設(shè)計(jì) 5 PLC的選型 5 CPU型號(hào)的選擇 6 模擬量模塊（SM）的確定 6 電源模塊的選用 8 8 9 93 液位控制系統(tǒng)的軟件設(shè)計(jì) 11 11 11 PLC程序設(shè)計(jì) 12 固定頻率的設(shè)定 12 PLC控制要求和策略 12 PLC程序控制流程 12 STEP 7編程過程 13 16 “組態(tài)王”軟件界面 17 上位機(jī)組態(tài)畫面的創(chuàng)建 17 上位機(jī)組態(tài)軟件數(shù)據(jù)詞典的創(chuàng)建 18 設(shè)置上位機(jī)通訊連接設(shè)備 194 系統(tǒng)調(diào)試 21結(jié)論 22參考文獻(xiàn) 23附錄 24致謝 321 引言過程控制通常是指連續(xù)生產(chǎn)過程的自動(dòng)控制，是自動(dòng)化技術(shù)最重要的組成部分之一。近幾十年來(lái)，自動(dòng)控制系統(tǒng)已被廣泛使用，在其研究與發(fā)展上也已趨于完備，而控制的概念更是應(yīng)用在許多生活周圍的事物。假若我們能使用此系統(tǒng)來(lái)自動(dòng)維持液位的高度，那么工作人員便可輕易的在操作室獲知整個(gè)設(shè)備的儲(chǔ)水狀況，因此，液面高度是工業(yè)控制過程中一個(gè)重要的參數(shù)，特別是在動(dòng)態(tài)的狀態(tài)下，采用適合的方法對(duì)液位進(jìn)行檢測(cè)、控制，不僅能收到
