工(gong)(gong)控(kong)機箱(xiang)(xiang)抗(kang)(kang)震(zhen)(zhen)：工(gong)(gong)控(kong)機箱(xiang)(xiang)在工(gong)(gong)作時，機箱(xiang)(xiang)內的(de)光驅和(he)硬盤會高速振動(dong)，振動(dong)容易導(dao)致光盤讀(du)錯(cuo)、硬盤磁道損(sun)壞甚(shen)至數據丟失，因此工(gong)(gong)控(kong)機箱(xiang)(xiang)抗(kang)(kang)震(zhen)(zhen)性(xing)能良(liang)好(hao)也是本(ben)案(an)的(de)關(guan)鍵結構設計方案(an)。考慮到(dao)工(gong)(gong)業控(kong)制(zhi)(zhi)柜的(de)耐腐蝕性(xing)、導(dao)電性(xing)和(he)導(dao)熱性(xing)的(de)內在要求(qiu)，我們的(de)工(gong)(gong)業控(kong)制(zhi)(zhi)箱(xiang)(xiang)減震(zhen)(zhen)系統采用金(jin)屬材料，比橡膠(jiao)材料更(geng)有效地降(jiang)低了(le)抗(kang)(kang)震(zhen)(zhen)性(xing)和(he)耐熱性(xing)。

嵌入(ru)(ru)式工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)計(ji)(ji)算(suan)(suan)(suan)機(ji)(ji)更流(liu)行的名稱是盒式計(ji)(ji)算(suan)(suan)(suan)機(ji)(ji)、便(bian)攜(xie)式工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)計(ji)(ji)算(suan)(suan)(suan)機(ji)(ji)或無風扇工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)計(ji)(ji)算(suan)(suan)(suan)機(ji)(ji)。它可(ke)(ke)以(yi)作為工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)控(kong)制器在工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)環境(jing)中可(ke)(ke)靠運行。一般來(lai)說，嵌入(ru)(ru)式工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)計(ji)(ji)算(suan)(suan)(suan)機(ji)(ji)是專門為工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)領域設計(ji)(ji)的小型計(ji)(ji)算(suan)(suan)(suan)機(ji)(ji)。早在上世(shi)紀90年代初，美國廣(guang)告(gao)公司就推出了(le)類(lei)似的工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)計(ji)(ji)算(suan)(suan)(suan)機(ji)(ji)。嵌入(ru)(ru)式工(gong)(gong)(gong)(gong)(gong)控(kong)機(ji)(ji)以(yi)其性能可(ke)(ke)靠、無風扇結構(gou)、體積小、價(jia)格低廉等優點在工(gong)(gong)(gong)(gong)(gong)控(kong)機(ji)(ji)中得(de)到(dao)了(le)廣(guang)泛的應用。

嵌(qian)入式(shi)工(gong)控機技術(shu)特點：。

機箱(xiang)內沒有(you)風扇，機箱(xiang)散(san)熱，可在惡(e)劣環境下使用。

配備高可(ke)靠的(de)工業電源，并有過(guo)壓、過(guo)流保護。

電(dian)源(yuan)和鍵(jian)盤配有電(dian)子鎖開(kai)關(guan)，可防(fang)止非法(fa)開(kai)、關(guan)和非法(fa)鍵(jian)盤輸入。

具有自診斷功能(neng)。

配有“看門狗”定時器(qi)，故障(zhang)時無需(xu)人工干預即可自動(dong)復位(wei)。

便于多(duo)任務(wu)調度和運行。

工(gong)(gong)業(ye)計算機的(de)軟件系(xi)統(tong)(tong)不(bu)同于(yu)普通(tong)(tong)計算機。工(gong)(gong)控(kong)(kong)機軟件系(xi)統(tong)(tong)比(bi)較單一，主要是實現特(te)定(ding)的(de)功能(neng)，而且(qie)由(you)于(yu)工(gong)(gong)控(kong)(kong)機通(tong)(tong)常使用(yong)的(de)處理器(qi)速(su)度不(bu)是很快，對編程的(de)要求也比(bi)較高(gao)。工(gong)(gong)業(ye)計算機通(tong)(tong)常使用(yong)模(mo)擬(ni)環境(jing)來開(kai)發程序并離線運行(xing)。普通(tong)(tong)計算機有大量(liang)的(de)通(tong)(tong)用(yong)應用(yong)，處理器(qi)的(de)速(su)度非常快，軟件開(kai)發系(xi)統(tong)(tong)完全在機器(qi)上(shang)，不(bu)需要其他環境(jing)的(de)支(zhi)持。

事物有兩(liang)個方(fang)面，工業(ye)計(ji)(ji)算(suan)機(ji)(ji)和普通(tong)計(ji)(ji)算(suan)機(ji)(ji)有更多相似的(de)特點(dian)。例如，雖然(ran)它們使用(yong)不同(tong)(tong)的(de)CPU，但這些(xie)CPU仍然(ran)是相同(tong)(tong)的(de)產品系(xi)列，內部結構相同(tong)(tong)：兩(liang)臺計(ji)(ji)算(suan)機(ji)(ji)的(de)總線結構基本(ben)相同(tong)(tong)，許多工業(ye)計(ji)(ji)算(suan)機(ji)(ji)是通(tong)用(yong)計(ji)(ji)算(suan)機(ji)(ji)的(de)簡化(hua)版，許多工業(ye)計(ji)(ji)算(suan)機(ji)(ji)具有與(yu)通(tong)用(yong)計(ji)(ji)算(suan)機(ji)(ji)相同(tong)(tong)或(huo)兼(jian)容的(de)接口。
