因PC機(jī)軟硬件資源豐富、產(chǎn)量大、價(jià)格低且質(zhì)量高,所以為廣大技術(shù)人員所熟悉和認(rèn)可。家用電腦逐步普及,目前,PC機(jī)占通用計(jì)算機(jī)95%以上。這是工業(yè)PC熱的基礎(chǔ)。搞工控的專家和技術(shù)人員自然想賦予PC總線更高的使命,擬讓它在過程控制、制造自動(dòng)化及樓宇自動(dòng)化等方面扮演重要角色。作為與DCS、PLC成鼎足之勢的IPC市場在擴(kuò)大,尤其是在我國。IPC機(jī)箱中插入各種高性能的CPU卡、RAM、ROM/FLash電子盤、各類外設(shè)卡及工業(yè)I/O卡,便構(gòu)成了一個(gè)工業(yè)過程控制IPC硬件系統(tǒng)。嵌入式PC和嵌入式計(jì)算機(jī),嵌入到設(shè)備內(nèi)部,提供用戶接口,管理數(shù)據(jù)輸入、輸出和指導(dǎo)設(shè)備工作的計(jì)算機(jī)。目前,中國在嵌入式設(shè)計(jì)中使用最多的還是80386和80486,這種CPU性能價(jià)格比高,有InTel、IBM、Cyixs、AMDT TI等著名CPU制造商支持。豐富的軟件(包括操作系統(tǒng)、開發(fā)工具和應(yīng)用軟件)支持。嵌入式PC能在惡劣環(huán)境下(如高溫、潮濕和震動(dòng)等)長期可靠工作。嵌入式PC平均無故障時(shí)間(MBTF)為1000~150000h,而臺(tái)式機(jī)僅為10000~15000h。硬件、軟件和工業(yè)PC差不多。
