西門(mén)子工業(yè)自動(dòng)化研究綜述
摘要：隨著科學(xué)技術(shù)的發(fā)展，工業(yè)控制的技術(shù)發(fā)展越來(lái)越快，工業(yè)控制技術(shù)使得工廠(chǎng)的生產(chǎn)效率大幅提高，而工業(yè)控制器PLC、工業(yè)PC等的應(yīng)用也大幅度提高了系統(tǒng)的自動(dòng)化程度，觸摸屏，人機(jī)界面的使用也使得工業(yè)現(xiàn)場(chǎng)的監(jiān)控更加方便，變頻器的發(fā)展也使得控制的精度越來(lái)越高?，F(xiàn)場(chǎng)總線(xiàn)的發(fā)展使得系統(tǒng)的通訊更加方便。本文主要對(duì)工業(yè)控制進(jìn)行一下初步的了解。
關(guān)鍵詞：PLC；人機(jī)界面；現(xiàn)場(chǎng)總線(xiàn)
引言
工業(yè)自動(dòng)化就是工業(yè)生產(chǎn)中的各種參數(shù)為控制目的，實(shí)現(xiàn)各種過(guò)程控制，在整個(gè)工業(yè)生產(chǎn)中，盡量減少人力的操作，而能充分利用動(dòng)物以外的能源與各種資訊來(lái)進(jìn)行生產(chǎn)工作，即稱(chēng)為工業(yè)自動(dòng)化生產(chǎn)，而使工業(yè)能進(jìn)行自動(dòng)生產(chǎn)之過(guò)程。
所謂的參數(shù)控制就是通過(guò)計(jì)算機(jī)控制系統(tǒng)，利用各種算法使系統(tǒng)達(dá)到穩(wěn)態(tài)。減少人力操作是通過(guò)使用計(jì)算機(jī)和可編程控制器就是PLC，來(lái)實(shí)現(xiàn)整個(gè)工廠(chǎng)的自動(dòng)控制的。監(jiān)控方面也采用了集中監(jiān)控和部分分散監(jiān)控相結(jié)合的原則，對(duì)工廠(chǎng)自動(dòng)化系統(tǒng)而言，使用人機(jī)界面軟件監(jiān)控，如西門(mén)子公司的WINcc，組態(tài)王，萬(wàn)維公司的InTouch，還有北京亞控科技發(fā)展有限公司開(kāi)發(fā)的組態(tài)王kingview等等。對(duì)系統(tǒng)局部的控制或者監(jiān)測(cè)可以使用觸摸屏。在運(yùn)動(dòng)控制和過(guò)程控制過(guò)程中，變頻器的使用也是十分的廣泛，主要用于交流電機(jī)的調(diào)速。而西門(mén)子公司對(duì)工廠(chǎng)自動(dòng)化控制過(guò)程所要用到的設(shè)備的生產(chǎn)和研發(fā)也是非常的到位的。
一．
PLC（Programmable Logic Controller）就是可編程邏輯控制器。德國(guó)西門(mén)子公司是上研制PLC早的少數(shù)幾個(gè)公司之一。歐洲臺(tái)PLC是由該公司在1973年研制成功的，1975年推出了SIMATIC S3系列PLC，1979年推出了SIMATIC S5系列，20世紀(jì)末又推出了SIMATIC S7系列的 PLC。
西門(mén)子S7系列PLC更接近于現(xiàn)場(chǎng)要求：高可靠性，減少了中間接口，具有多中斷、現(xiàn)場(chǎng)總線(xiàn)口、集成電位器、定時(shí)器、 計(jì)數(shù)器、碼盤(pán)接口等成功能，以及強(qiáng)大的網(wǎng)絡(luò)功能：RS232／485接口及多種現(xiàn)場(chǎng)總線(xiàn)標(biāo)準(zhǔn)、遠(yuǎn)程I/O，還可以作為DCS的下位站和PC機(jī)的下位機(jī)。同時(shí)支持多種編程語(yǔ)言，多種編程環(huán)境和可配套的集成軟件。【1】
