近日，由常州大學(xué)和揚(yáng)子石化聯(lián)合開發(fā)的大型石化裝置HART智能儀表實(shí)時(shí) 管理與診斷系統(tǒng)再次獲得了中國(guó)石油和化工自動(dòng)化行業(yè)協(xié)會(huì)科技進(jìn)步二等獎(jiǎng)。 專家組鑒定認(rèn)為，作為首個(gè)自主國(guó)產(chǎn)技術(shù)，該系統(tǒng)具有創(chuàng)新性和先進(jìn)性；其實(shí) 際運(yùn)行效果表明，主要技術(shù)指標(biāo)達(dá)到國(guó)外同類產(chǎn)品水平，經(jīng)濟(jì)效益顯著。目前 ，該系統(tǒng)已經(jīng)在揚(yáng)子石化、安慶石化等公司成功應(yīng)用
HART是美國(guó)ROSEMOUNT公司于1985年推出的一種用于現(xiàn)場(chǎng)智能儀表和控制 室設(shè)備之間的通信協(xié)議，目前已經(jīng)成為全球智能儀表的工業(yè)標(biāo)準(zhǔn)，基于HART協(xié) 議的智能儀表也已經(jīng)在石油化工裝置的生產(chǎn)控制系統(tǒng)中得到廣泛應(yīng)用。
然而，由于起步較晚，國(guó)內(nèi)HART智能儀表的實(shí)時(shí)管理與診斷系統(tǒng)技術(shù)一直 為國(guó)外某些跨國(guó)公司所壟斷，并且不向用戶開放系統(tǒng)的源代碼，使得國(guó)內(nèi)用戶 不能自由使用和深度開發(fā)，相關(guān)的儀表設(shè)備全部依賴進(jìn)口，為此石化企業(yè)需要 多支付更多的采購(gòu)費(fèi)用。并且，國(guó)外系統(tǒng)針對(duì)性不強(qiáng)，現(xiàn)場(chǎng)安裝、使用、操作 、售后服務(wù)均不方便，同時(shí)服務(wù)費(fèi)用和診斷費(fèi)用高昂。為此，從2004年開始， 常州大學(xué)和揚(yáng)子石化聯(lián)手開展技術(shù)開發(fā)，并先后在揚(yáng)子石化烯烴廠乙烯裝置10 萬(wàn)噸/年乙烯裂解爐和化工廠PTA一線和二線上應(yīng)用，均獲得成功。

“首先，它實(shí)現(xiàn)了智能化巡檢和智能監(jiān)控，減少了人工現(xiàn)場(chǎng)巡檢的風(fēng)險(xiǎn) ，尤其是裝置的高點(diǎn)遠(yuǎn)點(diǎn)、有污染的場(chǎng)所、人工不能到達(dá)的場(chǎng)所，都能實(shí)現(xiàn)巡 檢；其次，診斷效果更快更好，儀表故障診斷準(zhǔn)確率穩(wěn)定在99％以上，設(shè)備報(bào) 警準(zhǔn)確率在99%以上；并且解決了源代碼開放，推動(dòng)了國(guó)內(nèi)相關(guān)產(chǎn)業(yè)的發(fā)展。 ”研發(fā)人員揚(yáng)子石化烯烴廠電儀副總工程師楊金城介紹說，該系統(tǒng)對(duì)所管理的 現(xiàn)場(chǎng)儀表具有在線實(shí)時(shí)調(diào)校、在線實(shí)時(shí)診斷、在線實(shí)時(shí)監(jiān)控功能，對(duì)現(xiàn)場(chǎng)儀表 的維護(hù)方式由以往被動(dòng)性維護(hù)轉(zhuǎn)變?yōu)楝F(xiàn)在的預(yù)期性維護(hù)，從而使現(xiàn)場(chǎng)儀表的維 護(hù)功能由故障停車型轉(zhuǎn)向了預(yù)期診斷型，減少了儀表的故障率，提高了在線儀 表的穩(wěn)定性，避免了因儀表故障造成的波動(dòng)或停車風(fēng)險(xiǎn)，使揚(yáng)子烯烴廠乙烯裂 解爐上的先進(jìn)控制系統(tǒng)的投運(yùn)率由原來的75%提高到現(xiàn)在的95%以上；使揚(yáng)子化 工廠PTA一線和二線上的先進(jìn)控制系統(tǒng)的投運(yùn)率由原來的74%提高到現(xiàn)在的95% 以上；每年為企業(yè)帶來上千萬(wàn)元的經(jīng)濟(jì)效益。
該項(xiàng)目技術(shù)瓶頸的解決，是工業(yè)自動(dòng)化控制領(lǐng)域國(guó)內(nèi)具有自主知識(shí)產(chǎn)權(quán)技 術(shù)的重大突破，對(duì)構(gòu)建智能化數(shù)字工廠具有重大意義，具有很好的推廣條件和 市場(chǎng)前景。
