描述

MIC-2752

DCS系統(tǒng)是繼PLC之外的一大自動化控制系統(tǒng),它在化工、火電等領(lǐng)域的應用極為廣泛,但是生產(chǎn)方面的自動化技術(shù)需求進一步提高,傳統(tǒng)的DCS系統(tǒng)已不能滿足需要,需要進行技術(shù)升級。
  DCS系統(tǒng)由多臺計算機分別控制生產(chǎn)過程中多個控制回路,同時又可集中獲取數(shù)據(jù)、集中管理和集中控制的自動控制系統(tǒng)。分布式控制系統(tǒng)采用微處理機分別控制各個回路,而用中小型工業(yè)控制計算機或高性能的微處理機實施上一級的控制。
  經(jīng)過這些年來的不斷應用,DCS系統(tǒng)在行業(yè)發(fā)展的一些局限性逐步體現(xiàn)出來,DCS存在的問題:
 ?、?對1結(jié)構(gòu)。1臺儀表,1對傳輸線,單向傳輸1個信號。這種結(jié)構(gòu)造成接線龐雜、工程周期長、安裝費用高、維護困難。
 ?、诳煽啃圆?。模擬信號傳輸不僅精確度低,且易受干擾。為此采用各種措施提高抗干擾性和傳輸精確度,其結(jié)果是增加了成本。
 ?、凼Э貭顟B(tài)。操作員在控制室既不了解現(xiàn)場模擬儀表的工作狀況,也不能對其進行參數(shù)調(diào)整,更不能預測事故,導致操作員對其處于失控狀態(tài)。因操作員不能及時發(fā)現(xiàn)現(xiàn)場儀表故障,而發(fā)生事故已屢見不鮮。
 ?、芑ゲ僮餍圆?。盡管模擬儀表已統(tǒng)一4~20mA信號標準,可大部分技術(shù)參數(shù)仍由制造商自定,致使不同品牌儀表無法互換。因此導致用戶依賴制造廠,無法使用性能價格比最優(yōu)的配套儀表,甚至出現(xiàn)個別制造商壟斷市場的局面。

選擇深圳長欣,選擇放心,售后無憂大量現(xiàn)貨,當天順豐發(fā)貨!
主營:本特利,英維思,伍德沃德,??怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂,ACSO,力士樂等各大品牌的DCS系統(tǒng)配件,機器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點經(jīng)驗。
1、先通讀一遍“系統(tǒng)手冊”(不管能不能看懂,先了解個大概,以便學習編程時查找);
2、由位控邏輯入手,逐漸增加定時、計數(shù)等條件,把或、與、非關(guān)系理順;
3、進而練習整數(shù)運算、實數(shù)運算、類型轉(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(最好是有個物理回路驗證,比如變頻器+電機+測速傳感器);
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)機器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動器系列為主攻。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,學會一種至于其它的學習起來也就簡單了。
