描述

集中式數(shù)字控制系統(tǒng)于七八十年代占主導(dǎo)地位。采用單片機(jī)、PLC、SLC或微機(jī)作為控制器,控制器內(nèi)部傳輸?shù)氖菙?shù)字信 號(hào),因此克服了模擬儀表控制系統(tǒng)中模擬信號(hào)精度低的缺陷,提高了系統(tǒng)的抗干擾能力。集中式數(shù)字控制系統(tǒng)的優(yōu)點(diǎn)是易于根據(jù)全局情況進(jìn)行控制計(jì)算和判斷,在控制方式、控制機(jī)時(shí)的選擇上可以統(tǒng)一調(diào)度和安排;不足的是,對(duì)控制器本身要求很高,必須具有足夠的處理能力和極高的可靠性,當(dāng)系統(tǒng)任務(wù)增加時(shí),控制器的效率和可靠性將急劇下降。集散控制系統(tǒng)(DCS)于八、九十年代占主導(dǎo)地位。其核心思想是集中管理、分散控制,即管理與控制相分離,上位機(jī)用于集中監(jiān)視管理功能,若干臺(tái)下位機(jī)下放分散到現(xiàn)場(chǎng)實(shí)現(xiàn)分布式控制,各上下位機(jī)之間用控制網(wǎng)絡(luò)互連以實(shí)現(xiàn)相互之間的信息傳遞。因此,這種分布式的控制系統(tǒng)體系結(jié)構(gòu)有力地克服了集中式數(shù)字控制系統(tǒng)中對(duì)控制器處理能力和可靠性要求高的缺陷。在集散控制系統(tǒng)中,分布式控制思想的實(shí)現(xiàn)正是得益于網(wǎng)絡(luò)技術(shù)的發(fā)展和應(yīng)用,遺憾的是,不同的DCS廠家為達(dá)到壟斷經(jīng)營(yíng) 的目的而對(duì)其控制通訊網(wǎng)絡(luò)采用各自專(zhuān)用的封閉形式,不同廠家的DCS系統(tǒng)之間以及DCS與上層Intranet、Internet信息網(wǎng)絡(luò)之間難以實(shí)現(xiàn)網(wǎng)絡(luò)互連和信息共享,因此集散控制系統(tǒng)從該角度而言實(shí)質(zhì)是一種封閉專(zhuān)用的、不具可互操作性的分布式控制系統(tǒng)且DCS造價(jià)昂貴。在這種情況下,用戶(hù)對(duì)網(wǎng)絡(luò)控制系統(tǒng)提出了開(kāi)放化和降低成本的迫切要求。FCS正是順應(yīng)以上潮流而誕生,它用現(xiàn)場(chǎng)總線這一開(kāi)放的,具有可互操作的網(wǎng)絡(luò)將現(xiàn)場(chǎng)各控制器及儀表設(shè)備互連,構(gòu)成現(xiàn)場(chǎng)總線控制系統(tǒng),同時(shí)控制功能徹底下放到現(xiàn)場(chǎng),降低了安裝成本和維護(hù)費(fèi)用。因此,F(xiàn)CS實(shí)質(zhì)是 一種開(kāi)放的、具可互操作性的、徹底分散的分布式控制系統(tǒng),有望成為21世紀(jì)控制系統(tǒng)的主流產(chǎn)品?,F(xiàn)場(chǎng)總線是將自動(dòng)化最底層的現(xiàn)場(chǎng)控制器和現(xiàn)場(chǎng)智能儀表設(shè)備互連的實(shí)時(shí)控制通訊網(wǎng)絡(luò),遵循ISO的OSI開(kāi)放系統(tǒng)互連參考模型的全部或部分通訊協(xié)議。FCS則是用開(kāi)放的現(xiàn)場(chǎng)總線控制通訊網(wǎng)絡(luò)將自動(dòng)化最底層的現(xiàn)場(chǎng)控制器和現(xiàn)場(chǎng)智能儀表設(shè)備互連的實(shí)時(shí)網(wǎng)絡(luò)控制系統(tǒng)

選擇深圳長(zhǎng)欣,選擇放心,售后無(wú)憂(yōu)大量現(xiàn)貨,當(dāng)天順豐發(fā)貨!
主營(yíng):本特利,英維思,伍德沃德,??怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門(mén)子、摩托羅拉、GE發(fā)那科、安川、博世力士樂(lè),ACSO,力士樂(lè)等各大品牌的DCS系統(tǒng)配件,機(jī)器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗(yàn)。
1、先通讀一遍“系統(tǒng)手冊(cè)”(不管能不能看懂,先了解個(gè)大概,以便學(xué)習(xí)編程時(shí)查找);
2、由位控邏輯入手,逐漸增加定時(shí)、計(jì)數(shù)等條件,把或、與、非關(guān)系理順;
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實(shí)數(shù)運(yùn)算、類(lèi)型轉(zhuǎn)換;
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個(gè)物理回路驗(yàn)證,比如變頻器+電機(jī)+測(cè)速傳感器);
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制(盡量避免跳轉(zhuǎn),非跳不可時(shí)也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動(dòng)器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學(xué)會(huì)一種至于其它的學(xué)習(xí)起來(lái)也就簡(jiǎn)單了。
