身在自動(dòng)化行業(yè)有多少人知道dcs系統(tǒng)中動(dòng)態(tài)數(shù)據(jù)服務(wù)器的設(shè)置方法呢。本文針對(duì)其設(shè)置方法做一個(gè)詳細(xì)介紹，供大家參考。
dcs控制系統(tǒng)屬于基礎(chǔ)自動(dòng)化，mis系統(tǒng)側(cè)重于辦公自動(dòng)化。這兩者在反映速度上的區(qū)別很大，dcs是屬于秒級(jí)的，而mis是以小時(shí)或更長(zhǎng)時(shí)間為單位的。所以這兩者之間必須要有隔離設(shè)備，這個(gè)隔離設(shè)備就是動(dòng)態(tài)數(shù)據(jù)服務(wù)器。它的功能是生產(chǎn)過(guò)程監(jiān)控;歷史數(shù)據(jù)的存儲(chǔ)及管理;統(tǒng)計(jì)質(zhì)量控制;設(shè)備預(yù)防性維護(hù);設(shè)備故障診斷;生產(chǎn)優(yōu)化等。
dcs采集現(xiàn)場(chǎng)的生產(chǎn)過(guò)程數(shù)據(jù)通過(guò)通訊網(wǎng)絡(luò)把數(shù)據(jù)傳給操作站和動(dòng)態(tài)數(shù)據(jù)服務(wù)器。動(dòng)態(tài)數(shù)據(jù)服務(wù)器是采集生產(chǎn)全過(guò)程的模擬信號(hào)或邏輯信號(hào)，所以它的采集速度是海量的。要經(jīng)過(guò)數(shù)據(jù)淘金，將信號(hào)送到生產(chǎn)管理部門。
通常情況下，一個(gè)企業(yè)往往有幾種不同牌號(hào)的dcs、plc，要把這幾種信號(hào)都集中到動(dòng)態(tài)數(shù)據(jù)服務(wù)器中，最好要選擇一個(gè)通用顯示平臺(tái)。在這個(gè)平臺(tái)上來(lái)顯示不同型號(hào)的dcs、plc的信號(hào)。通用顯示平臺(tái)可采用fix、intouch、組態(tài)王、synall等軟件，開(kāi)發(fā)各種dcs和plc的驅(qū)動(dòng)軟件。
最近出廠的dcs采用通用操作站，它采用nt操作系統(tǒng)，監(jiān)控軟件就是fix、intouch.不同dcs型號(hào)采用不同的驅(qū)動(dòng)軟件。各種dcs之間信號(hào)傳輸采用opc服務(wù)器聯(lián)接，也可以把少量的信號(hào)送到mis系統(tǒng)的服務(wù)器中。fix、intouch等軟件都能存儲(chǔ)歷史數(shù)據(jù)，幾十個(gè)信號(hào)可存儲(chǔ)280天之多。如要存儲(chǔ)更多的歷史數(shù)據(jù)，可以采用osi歷史數(shù)據(jù)庫(kù)，它可以存儲(chǔ)三年以上。這些通用監(jiān)控軟件都有osi的接口。
老一代的dcs系統(tǒng)的操作站無(wú)論操作系統(tǒng)還是監(jiān)控軟件都是專用的，和其它系統(tǒng)通訊都非常困難。如要建立系統(tǒng)間的互聯(lián)，通過(guò)計(jì)算機(jī)接口單元建立動(dòng)態(tài)數(shù)據(jù)服務(wù)器，監(jiān)控軟件仍然可以使用通用的，在nt平臺(tái)上運(yùn)行，但它的數(shù)據(jù)只能上行，不能下行。在設(shè)計(jì)mis系統(tǒng)過(guò)程中，最好使用動(dòng)態(tài)數(shù)據(jù)服務(wù)器，不要把dcs和plc數(shù)據(jù)直接送到web否則會(huì)影響到 dcs、plc的正常運(yùn)行。至于究竟需要建立多少個(gè)動(dòng)態(tài)數(shù)據(jù)服務(wù)器，由所需采集的數(shù)據(jù)量和數(shù)據(jù)安 全決定(一般情況下，可達(dá)10000點(diǎn))。
