為什么工控主板(ban)的(de)價(jia)格比商用主板(ban)高?相(xiang)信很多用戶朋友都(dou)有這個疑問，下面澤創偉業小(xiao)編就來給(gei)大家分析下。
一、保護功能
商用主板沒有提供的(de)任何的(de)保護(hu)功能;
工控主板通過特(te)殊設計，在(zai)遇(yu)到死機等(deng)異常情況，可以實現看(kan)門狗(gou)自動(dong)重(zhong)新啟動(dong)、防浪(lang)涌沖擊等(deng)功能，全力的保證系統(tong)在(zai)惡劣(lie)環境的高穩(wen)定性(xing)的要求。
二、工作溫度與散熱方式
商用(yong)主板基本只能(neng)在5℃~38℃之間的(de)(de)環境溫度中(zhong)使用(yong)，對機(ji)構的(de)(de)散熱要求低，講(jiang)究外觀夠炫(xuan)夠酷。
工控主(zhu)板(ban)可(ke)以(yi)在(zai)-20℃~60℃之間的(de)(de)(de)環境(jing)中(zhong)穩定(ding)、無故障的(de)(de)(de)工作(zuo)，甚至某些工業(ye)主(zhu)板(ban)采用特(te)殊(shu)的(de)(de)(de)寬(kuan)溫設計，溫度范圍可(ke)達-20度~70度。這對(dui)機構的(de)(de)(de)散(san)熱(re)方案，散(san)熱(re)效(xiao)率(lv)都是(shi)一個嚴峻的(de)(de)(de)考驗。在(zai)工控主(zhu)板(ban)機構的(de)(de)(de)散(san)熱(re)設計上，必須(xu)使用的(de)(de)(de)特(te)殊(shu)散(san)熱(re)設計，甚至還采用全(quan)鋁制的(de)(de)(de)機構外殼，而且(qie)對(dui)CPU、南北橋和(he)硬盤等發熱(re)大戶(hu)，進(jin)行特(te)殊(shu)處理，保證工控主(zhu)板(ban)和(he)整機的(de)(de)(de)正常運行。
很(hen)多工控(kong)機(ji)由于在惡劣(lie)的(de)(de)應用(yong)(yong)(yong)環(huan)(huan)境下(xia)(例(li)如潮濕、振(zhen)動、多塵、輻(fu)射、高(gao)(gao)溫等(deng)等(deng)應用(yong)(yong)(yong)環(huan)(huan)境)使(shi)用(yong)(yong)(yong)，空氣中的(de)(de)塵埃(ai)和鹽(yan)分，都會對(dui)(dui)主(zhu)(zhu)板造(zao)(zao)成(cheng)腐蝕，影響主(zhu)(zhu)板的(de)(de)正常使(shi)用(yong)(yong)(yong)，因此很(hen)多工控(kong)機(ji)有必要采(cai)用(yong)(yong)(yong)無(wu)風扇的(de)(de)機(ji)箱結構(gou)(gou)(gou)，防止(zhi)惡劣(lie)環(huan)(huan)境對(dui)(dui)系統造(zao)(zao)成(cheng)傷(shang)害。但是全密封無(wu)風扇的(de)(de)結構(gou)(gou)(gou)，因為熱(re)源的(de)(de)互相干擾，對(dui)(dui)主(zhu)(zhu)板的(de)(de)性(xing)能和穩定性(xing)的(de)(de)要求比較(jiao)高(gao)(gao)，對(dui)(dui)機(ji)構(gou)(gou)(gou)的(de)(de)散(san)熱(re)方式和散(san)熱(re)效能的(de)(de)要求很(hen)高(gao)(gao)，務必要將積熱(re)有效散(san)發(fa)出去。
三、使用環境
工控主板常在惡劣環境下工作(壽命期內永久開機、氣候惡劣、潮濕、振動、多塵、輻射、高溫等等)，而這些環境下是商用主板無法勝任，當今商業主板大部分只能運行在安定的環境下(工作時間短、室內、常溫等等)。
四、主板元器件的用料與設計：
商用主板：
商用(yong)(yong)主板(ban)由(you)于其更新換代的(de)(de)速度比(bi)較(jiao)(jiao)快，且對(dui)產(chan)品的(de)(de)穩定(ding)性及使用(yong)(yong)環(huan)境(jing)的(de)(de)要求比(bi)較(jiao)(jiao)低(di)(di)，故此追求的(de)(de)是(shi)產(chan)品的(de)(de)時效性，以(yi)及本身(shen)產(chan)品的(de)(de)市場(chang)定(ding)位(wei)，對(dui)元器件(jian)選擇要求上(shang)一般只需滿足系統運行(xing)2到3年的(de)(de)使用(yong)(yong)壽命即(ji)可(3年之(zhi)后大部(bu)分已經更新換代了)，元器件(jian)的(de)(de)用(yong)(yong)料上(shang)使用(yong)(yong)普(pu)通(tong)級(ji)別的(de)(de)就可以(yi)了。例如電(dian)容，商用(yong)(yong)主板(ban)都是(shi)大量(liang)使用(yong)(yong)普(pu)通(tong)的(de)(de)電(dian)解電(dian)容，一是(shi)出于商用(yong)(yong)市場(chang)產(chan)品的(de)(de)使用(yong)(yong)考(kao)慮，二(er)是(shi)為降低(di)(di)主板(ban)的(de)(de)成(cheng)本考(kao)慮。
工控主(zhu)板(ban)：
1)工(gong)控主板(ban)的元器件
工控主(zhu)板(ban)選料會選用(yong)經過長時間(jian)，高(gao)要求(qiu)驗證元(yuan)(yuan)器件(jian)，用(yong)以(yi)保(bao)證產品在(zai)(zai)惡劣條件(jian)下(xia)高(gao)可靠(kao)性要求(qiu)。例(li)如工控主(zhu)板(ban)的元(yuan)(yuan)器件(jian)需(xu)要適應寬(kuan)溫環境(-20℃~60℃)，如固態(tai)電(dian)容器，保(bao)證在(zai)(zai)惡劣環境下(xia)(壽命期內永久開機、氣(qi)候惡劣、潮(chao)濕、振動、多(duo)塵、輻射、高(gao)溫等(deng)(deng)等(deng)(deng))正常工作;主(zhu)板(ban)元(yuan)(yuan)器件(jian)需(xu)要耐高(gao)溫、抗潮(chao)濕等(deng)(deng)等(deng)(deng)。
2)工控主(zhu)板的電(dian)容(rong)
工控(kong)(kong)主(zhu)(zhu)板(ban)(ban)(ban)采用(yong)(yong)(yong)的(de)(de)是高(gao)質量的(de)(de)貼片式(shi)(shi)(shi)的(de)(de)固態(tai)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)、鉭(tan)(tan)、陶瓷電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)，即使(shi)(shi)(shi)使(shi)(shi)(shi)用(yong)(yong)(yong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)，對其(qi)品(pin)質、性能及(ji)壽(shou)命要求也遠高(gao)于(yu)商(shang)用(yong)(yong)(yong)產(chan)品(pin)，現在(zai)的(de)(de)工控(kong)(kong)主(zhu)(zhu)板(ban)(ban)(ban)都基(ji)本(ben)上(shang)采用(yong)(yong)(yong)固態(tai)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)，特別中(zhong)高(gao)端的(de)(de)工控(kong)(kong)主(zhu)(zhu)板(ban)(ban)(ban)。商(shang)用(yong)(yong)(yong)主(zhu)(zhu)板(ban)(ban)(ban)基(ji)本(ben)都是大(da)量采用(yong)(yong)(yong)針腳式(shi)(shi)(shi)的(de)(de)大(da)電(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)，因(yin)為(wei)大(da)電(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)成本(ben)低(di)、容(rong)(rong)(rong)(rong)(rong)(rong)(rong)值大(da)一(yi)個(ge)可以頂多(duo)個(ge)貼片或坦電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)。從(cong)性質來說，電(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)穩定性不及(ji)鉭(tan)(tan)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)、陶瓷電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)高(gao)，壽(shou)命不及(ji)它們(men)長，耐(nai)高(gao)溫程度(du)不及(ji)它們(men)好。貼片式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)比(bi)針腳式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)更(geng)加穩定。從(cong)價(jia)格上(shang)，鉭(tan)(tan)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)比(bi)普通(tong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)要貴，且由于(yu)鉭(tan)(tan)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)量較小，使(shi)(shi)(shi)用(yong)(yong)(yong)在(zai)主(zhu)(zhu)板(ban)(ban)(ban)上(shang)時，需要使(shi)(shi)(shi)用(yong)(yong)(yong)更(geng)多(duo)數量的(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)，單單鉭(tan)(tan)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)的(de)(de)成本(ben)就(jiu)是電(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)的(de)(de)幾(ji)十倍(bei)，這也是導(dao)致工控(kong)(kong)主(zhu)(zhu)板(ban)(ban)(ban)比(bi)商(shang)用(yong)(yong)(yong)主(zhu)(zhu)板(ban)(ban)(ban)成本(ben)價(jia)格高(gao)的(de)(de)原因(yin)之(zhi)一(yi)。隨(sui)著國產(chan)固態(tai)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)器廠家(jia)越(yue)來越(yue)多(duo)，固態(tai)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)器的(de)(de)價(jia)格的(de)(de)下降，現在(zai)的(de)(de)高(gao)檔次的(de)(de)商(shang)用(yong)(yong)(yong)主(zhu)(zhu)板(ban)(ban)(ban)都在(zai)使(shi)(shi)(shi)用(yong)(yong)(yong)固態(tai)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)器。
3)工控主板的PCB
商用主板(ban)(ban)(ban)采(cai)用的(de)(de)是(shi)4層(ceng)(ceng)(ceng)PCB設計，一般的(de)(de)PCB線路(lu)(lu)板(ban)(ban)(ban)分有(you)四層(ceng)(ceng)(ceng)，最上和最下的(de)(de)兩層(ceng)(ceng)(ceng)是(shi)信號層(ceng)(ceng)(ceng)，中間(jian)兩層(ceng)(ceng)(ceng)是(shi)接(jie)地層(ceng)(ceng)(ceng)和電源層(ceng)(ceng)(ceng)，將接(jie)地和電源層(ceng)(ceng)(ceng)放在中間(jian)。工業主板(ban)(ban)(ban)采(cai)用的(de)(de)是(shi)6層(ceng)(ceng)(ceng)以上PCB線路(lu)(lu)板(ban)(ban)(ban)設計，其設計是(shi)為了加強主板(ban)(ban)(ban)的(de)(de)抗電磁干擾、電磁兼容能力，增(zeng)強主板(ban)(ban)(ban)的(de)(de)穩定(ding)性等等。
4)工控(kong)主板的壽命
與商用主(zhu)板2到(dao)3年(nian)使(shi)用壽命不同，大(da)多數的工(gong)控主(zhu)板壽命要求在3年(nian)以上，部(bu)分高品質(zhi)的工(gong)控主(zhu)板，使(shi)用壽命甚至達到(dao)5—7年(nian)。
一、保護功能
商用主板沒有提供的(de)任何的(de)保護(hu)功能;
工控主板通過特(te)殊設計，在(zai)遇(yu)到死機等(deng)異常情況，可以實現看(kan)門狗(gou)自動(dong)重(zhong)新啟動(dong)、防浪(lang)涌沖擊等(deng)功能，全力的保證系統(tong)在(zai)惡劣(lie)環境的高穩(wen)定性(xing)的要求。
二、工作溫度與散熱方式
商用(yong)主板基本只能(neng)在5℃~38℃之間的(de)(de)環境溫度中(zhong)使用(yong)，對機(ji)構的(de)(de)散熱要求低，講(jiang)究外觀夠炫(xuan)夠酷。
工控主(zhu)板(ban)可(ke)以(yi)在(zai)-20℃~60℃之間的(de)(de)(de)環境(jing)中(zhong)穩定(ding)、無故障的(de)(de)(de)工作(zuo)，甚至某些工業(ye)主(zhu)板(ban)采用特(te)殊(shu)的(de)(de)(de)寬(kuan)溫設計，溫度范圍可(ke)達-20度~70度。這對(dui)機構的(de)(de)(de)散(san)熱(re)方案，散(san)熱(re)效(xiao)率(lv)都是(shi)一個嚴峻的(de)(de)(de)考驗。在(zai)工控主(zhu)板(ban)機構的(de)(de)(de)散(san)熱(re)設計上，必須(xu)使用的(de)(de)(de)特(te)殊(shu)散(san)熱(re)設計，甚至還采用全(quan)鋁制的(de)(de)(de)機構外殼，而且(qie)對(dui)CPU、南北橋和(he)硬盤等發熱(re)大戶(hu)，進(jin)行特(te)殊(shu)處理，保證工控主(zhu)板(ban)和(he)整機的(de)(de)(de)正常運行。
很(hen)多工控(kong)機(ji)由于在惡劣(lie)的(de)(de)應用(yong)(yong)(yong)環(huan)(huan)境下(xia)(例(li)如潮濕、振(zhen)動、多塵、輻(fu)射、高(gao)(gao)溫等(deng)等(deng)應用(yong)(yong)(yong)環(huan)(huan)境)使(shi)用(yong)(yong)(yong)，空氣中的(de)(de)塵埃(ai)和鹽(yan)分，都會對(dui)(dui)主(zhu)(zhu)板造(zao)(zao)成(cheng)腐蝕，影響主(zhu)(zhu)板的(de)(de)正常使(shi)用(yong)(yong)(yong)，因此很(hen)多工控(kong)機(ji)有必要采(cai)用(yong)(yong)(yong)無(wu)風扇的(de)(de)機(ji)箱結構(gou)(gou)(gou)，防止(zhi)惡劣(lie)環(huan)(huan)境對(dui)(dui)系統造(zao)(zao)成(cheng)傷(shang)害。但是全密封無(wu)風扇的(de)(de)結構(gou)(gou)(gou)，因為熱(re)源的(de)(de)互相干擾，對(dui)(dui)主(zhu)(zhu)板的(de)(de)性(xing)能和穩定性(xing)的(de)(de)要求比較(jiao)高(gao)(gao)，對(dui)(dui)機(ji)構(gou)(gou)(gou)的(de)(de)散(san)熱(re)方式和散(san)熱(re)效能的(de)(de)要求很(hen)高(gao)(gao)，務必要將積熱(re)有效散(san)發(fa)出去。
