為何要獨(dú)立設(shè)置ESD系統(tǒng)呢?當(dāng)然一般安全聯(lián)鎖保護(hù)功能也可由DCS來(lái)實(shí)現(xiàn)。但是對(duì)于較大規(guī)模的緊急停車系
統(tǒng)應(yīng)按照安全獨(dú)立原則與DCS分開(kāi)設(shè)置,這樣做主要有以下幾方面原因:
(1)降低控制功能和安全功能同時(shí)失效的概率,當(dāng)維護(hù)DCS部分故障時(shí)也不會(huì)危及安全保護(hù)系統(tǒng);
(2)對(duì)于大型裝置或旋轉(zhuǎn)機(jī)械設(shè)備而言,緊急停車系統(tǒng)響應(yīng)速度越快越好。這有利于保護(hù)設(shè)備,避免事故擴(kuò)
大;并有利于分辨事故原因記錄。而DCS處理大量過(guò)程監(jiān)測(cè)信息,因此其響應(yīng)速度難以作得很快;
(3)DCS系統(tǒng)是過(guò)程控制系統(tǒng),是動(dòng)態(tài)的,需要人工頻繁的干預(yù),這有可能引起人為誤動(dòng)作;而ESD是靜態(tài)
的,不需要人為干預(yù),這樣設(shè)置ESD可以避免人為誤動(dòng)作。
其他含義
ESD:ESD(Electro-Static discharge)的意思是“靜電釋放”、“靜電放電”。
防靜電ESD系統(tǒng)解決方案
隨著微電子技術(shù)的飛速發(fā)展,靜電對(duì)其生產(chǎn)制造過(guò)程中造成的危害越來(lái)越明顯,同時(shí)也為靜電防護(hù)技術(shù)本身提出
更高的要求。
ESD防護(hù)體系對(duì)于不同規(guī)模和水平的企業(yè)要求也不同。目前主要在微電子企業(yè)比較規(guī)范。大體分為三類:一是
靜電防護(hù)要求的企業(yè),如生產(chǎn)晶片、磁頭的生產(chǎn)商;二是整機(jī)、電子器件、電子成品生產(chǎn)企業(yè),如IBM、
Motorola等;三是承接OEM、ODM的加工企業(yè)。他們?cè)诮⒁?guī)范的ESD防護(hù)體系的規(guī)模水平和成本投入也有很
