PC-ACR8020-03

目前計(jì)算機(jī)控制系統(tǒng)已經(jīng)基本上實(shí)現(xiàn)開(kāi)放，主要?dú)w功于DCS的操作站和控制器都采用以PC機(jī)為基礎(chǔ)的硬件結(jié)構(gòu)。操作站的操作系統(tǒng)采用Windows NT/2000，用戶希望能制訂一套像IEC 61131那樣的編程標(biāo)準(zhǔn)。因?yàn)榭刂破鞯木幊汰h(huán)境如具備IEC 61131標(biāo)準(zhǔn)，能給用戶在控制器組態(tài)方面提供很大方便。
對(duì)于DCS來(lái)說(shuō)，除操作系統(tǒng)以外，在系統(tǒng)中所用軟件可分為3大部分：(1)標(biāo)簽數(shù)據(jù)庫(kù)：包括讀取系統(tǒng)的輸入和輸出、控制回路，數(shù)據(jù)庫(kù)功能的擴(kuò)展，OPC數(shù)據(jù)的通信；(2)顯示：包括顯示動(dòng)態(tài)流程圖、趨勢(shì)、報(bào)警；(3)控制器組態(tài)平臺(tái)：這部分被稱為工程師站軟件，目前已經(jīng)有IEC 61131標(biāo)準(zhǔn)。
標(biāo)簽數(shù)據(jù)庫(kù)和顯示軟件安裝在人機(jī)界面中?，F(xiàn)在各家軟件公司對(duì)標(biāo)簽的定義是自己規(guī)定的，顯示的部件和標(biāo)簽數(shù)據(jù)庫(kù)及屬性的描述也是各家自己定義的，所以給用戶造成極大不便，用戶要花費(fèi)很多時(shí)間來(lái)掌握這些組態(tài)技巧，學(xué)習(xí)繁瑣的工具手段，而不是把時(shí)間用在該用的地方，去進(jìn)行優(yōu)化控制。
在用戶系統(tǒng)升級(jí)時(shí)，操作站的各項(xiàng)工作都要重來(lái)，如作圖、文本，沒(méi)有繼承性可言，每次都要重作。如在更換系統(tǒng)時(shí)，也是重新作圖，即使只更換操作站，其工作量也很大。其實(shí)，控制系統(tǒng)更換了，現(xiàn)場(chǎng)的被控對(duì)象并沒(méi)有變化，閥門(mén)還是閥門(mén)，變送器還是變送器，管道還是管道?？偟膩?lái)說(shuō)，被控對(duì)象是不變的，只不過(guò)各個(gè)系統(tǒng)的監(jiān)控軟件對(duì)它們的描述改變了。即便是新建的項(xiàng)目，用的變送器、閥門(mén)也是一樣的，只要對(duì)它們的描述規(guī)定了，老的基建項(xiàng)目有部分圖形在新項(xiàng)目中還是可以用的。即使是部分繼承，也能節(jié)省許多人力。另外，浪費(fèi)更大的還是在新老人員交接的時(shí)侯，新人都要重新學(xué)習(xí)一遍，經(jīng)過(guò)幾年以后才能走向正規(guī)。如果老技術(shù)人員是在一個(gè)標(biāo)準(zhǔn)的環(huán)境下工作，他們的工作很容易傳給新一代的技術(shù)人員，而不必在低水平上重復(fù)。
需要制訂標(biāo)準(zhǔn)的另外一個(gè)原因是，由于DCS、PLC要與企業(yè)局域網(wǎng)相聯(lián)，如果現(xiàn)在有幾十種監(jiān)控軟件，相互之間需要轉(zhuǎn)換，編寫(xiě)轉(zhuǎn)換軟件需要有上百個(gè)。因?yàn)楝F(xiàn)在的軟件是“所見(jiàn)即所得”的，它帶來(lái)了很大麻煩。這種軟件對(duì)于轉(zhuǎn)換來(lái)說(shuō)，它不是表意的。如果我們采用XML(Extensible Markup Language)方法，它使得開(kāi)發(fā)人員能夠創(chuàng)建以邏輯內(nèi)容而不是以格式為基礎(chǔ)的標(biāo)記結(jié)構(gòu)。這將使人和計(jì)算機(jī)能夠更容易地在文檔內(nèi)搜索具體的基于內(nèi)容的信息，而不是僅僅搜索一個(gè)頁(yè)面的文本。采用XML方法，可以作到部分表意。因此，就不需要編寫(xiě)那么多軟件。
