為什么工控主(zhu)板(ban)的價(jia)格比商用主(zhu)板(ban)高?相(xiang)信很多用戶朋友(you)都有這個疑問,下面澤創(chuang)偉業小編就來給大家(jia)分析下。
一、保護功能
商用主板沒有提供的任(ren)何(he)的保護(hu)功能(neng);
工控主板通過特殊設計,在遇到死機等(deng)異(yi)常情況,可以實現看(kan)門(men)狗自動重(zhong)新啟動、防浪涌沖(chong)擊(ji)等(deng)功能(neng),全力的(de)保(bao)證(zheng)系統在惡劣環境的(de)高穩定性(xing)的(de)要求。
二、工作溫度與散熱方式
商用主(zhu)板基本(ben)只能在5℃~38℃之間的環境(jing)溫度中使用,對機構的散熱要(yao)求(qiu)低(di),講究外觀夠炫夠酷(ku)。
工控主(zhu)板可以在-20℃~60℃之間的(de)環境(jing)中穩定、無故障的(de)工作,甚(shen)至某些(xie)工業主(zhu)板采用(yong)特殊的(de)寬溫設計(ji),溫度(du)(du)范圍可達-20度(du)(du)~70度(du)(du)。這對(dui)機構的(de)散(san)(san)熱方案,散(san)(san)熱效(xiao)率都是一個嚴(yan)峻的(de)考驗。在工控主(zhu)板機構的(de)散(san)(san)熱設計(ji)上,必須使用(yong)的(de)特殊散(san)(san)熱設計(ji),甚(shen)至還采用(yong)全鋁(lv)制的(de)機構外殼(ke),而且(qie)對(dui)CPU、南(nan)北橋和硬盤(pan)等發熱大(da)戶(hu),進行特殊處理,保(bao)證工控主(zhu)板和整機的(de)正常運(yun)行。
很(hen)(hen)多工控機(ji)(ji)由于(yu)在惡(e)劣(lie)(lie)的(de)(de)(de)(de)應用(yong)環境下(例如潮濕、振(zhen)動、多塵、輻射、高(gao)溫等(deng)等(deng)應用(yong)環境)使(shi)用(yong),空氣中的(de)(de)(de)(de)塵埃(ai)和鹽(yan)分,都會對(dui)主(zhu)板(ban)造成腐(fu)蝕,影(ying)響主(zhu)板(ban)的(de)(de)(de)(de)正常(chang)使(shi)用(yong),因此很(hen)(hen)多工控機(ji)(ji)有必(bi)要(yao)(yao)采用(yong)無風(feng)扇的(de)(de)(de)(de)機(ji)(ji)箱結構,防止(zhi)惡(e)劣(lie)(lie)環境對(dui)系統造成傷(shang)害。但是全密封無風(feng)扇的(de)(de)(de)(de)結構,因為(wei)熱(re)源的(de)(de)(de)(de)互(hu)相干擾,對(dui)主(zhu)板(ban)的(de)(de)(de)(de)性能(neng)和穩定性的(de)(de)(de)(de)要(yao)(yao)求(qiu)(qiu)比較高(gao),對(dui)機(ji)(ji)構的(de)(de)(de)(de)散(san)熱(re)方式和散(san)熱(re)效能(neng)的(de)(de)(de)(de)要(yao)(yao)求(qiu)(qiu)很(hen)(hen)高(gao),務必(bi)要(yao)(yao)將(jiang)積(ji)熱(re)有效散(san)發出去。
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(ban):
商(shang)(shang)用(yong)(yong)主板(ban)由于其更(geng)新換代的速度比較快,且對產品的穩定(ding)性及使(shi)(shi)用(yong)(yong)環境的要求比較低,故此追求的是(shi)產品的時效性,以及本身產品的市場(chang)定(ding)位,對元(yuan)器(qi)件選(xuan)擇要求上一般(ban)只(zhi)需滿足系統運行2到3年(nian)的使(shi)(shi)用(yong)(yong)壽命即可(3年(nian)之后大部分已經更(geng)新換代了(le)),元(yuan)器(qi)件的用(yong)(yong)料上使(shi)(shi)用(yong)(yong)普(pu)通級別的就(jiu)可以了(le)。例如電(dian)容,商(shang)(shang)用(yong)(yong)主板(ban)都是(shi)大量使(shi)(shi)用(yong)(yong)普(pu)通的電(dian)解電(dian)容,一是(shi)出于商(shang)(shang)用(yong)(yong)市場(chang)產品的使(shi)(shi)用(yong)(yong)考慮(lv),二是(shi)為降低主板(ban)的成本考慮(lv)。
工控(kong)主板(ban):
1)工控主板的元器件
工控(kong)主(zhu)板(ban)(ban)選(xuan)料會選(xuan)用經過(guo)長時(shi)間(jian),高要(yao)(yao)求驗證元(yuan)器(qi)(qi)(qi)件,用以保證產品在惡(e)劣(lie)條件下高可靠(kao)性(xing)要(yao)(yao)求。例如工控(kong)主(zhu)板(ban)(ban)的元(yuan)器(qi)(qi)(qi)件需(xu)要(yao)(yao)適應寬溫(wen)環(huan)境(jing)(-20℃~60℃),如固態(tai)電容(rong)器(qi)(qi)(qi),保證在惡(e)劣(lie)環(huan)境(jing)下(壽命(ming)期(qi)內永久開(kai)機、氣候惡(e)劣(lie)、潮(chao)濕、振動、多塵、輻射(she)、高溫(wen)等(deng)(deng)等(deng)(deng))正(zheng)常工作;主(zhu)板(ban)(ban)元(yuan)器(qi)(qi)(qi)件需(xu)要(yao)(yao)耐高溫(wen)、抗潮(chao)濕等(deng)(deng)等(deng)(deng)。
2)工控主(zhu)板的電容
工(gong)控主(zhu)板(ban)(ban)采用(yong)(yong)的(de)(de)(de)(de)(de)是(shi)高(gao)質量的(de)(de)(de)(de)(de)貼片(pian)式(shi)(shi)的(de)(de)(de)(de)(de)固(gu)態(tai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)、鉭、陶瓷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong),即使(shi)使(shi)用(yong)(yong)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong),對其品質、性(xing)能及壽命要求也(ye)遠(yuan)高(gao)于商(shang)用(yong)(yong)產(chan)品,現在(zai)的(de)(de)(de)(de)(de)工(gong)控主(zhu)板(ban)(ban)都(dou)基本(ben)上采用(yong)(yong)固(gu)態(tai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong),特別中高(gao)端的(de)(de)(de)(de)(de)工(gong)控主(zhu)板(ban)(ban)。商(shang)用(yong)(yong)主(zhu)板(ban)(ban)基本(ben)都(dou)是(shi)大(da)(da)量采用(yong)(yong)針(zhen)腳式(shi)(shi)的(de)(de)(de)(de)(de)大(da)(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong),因(yin)為大(da)(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)成本(ben)低、容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)值大(da)(da)一個可以(yi)頂多個貼片(pian)或(huo)坦電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)。從(cong)(cong)性(xing)質來說,電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)穩定性(xing)不及鉭電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)、陶瓷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)高(gao),壽命不及它(ta)們(men)長(chang),耐(nai)高(gao)溫程度不及它(ta)們(men)好。貼片(pian)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)比針(zhen)腳式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)更加穩定。從(cong)(cong)價格(ge)上,鉭電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)比普通(tong)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)要貴,且(qie)由于鉭電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)量較小(xiao),使(shi)用(yong)(yong)在(zai)主(zhu)板(ban)(ban)上時,需要使(shi)用(yong)(yong)更多數量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong),單單鉭電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)的(de)(de)(de)(de)(de)成本(ben)就(jiu)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)的(de)(de)(de)(de)(de)幾(ji)十(shi)倍,這也(ye)是(shi)導致工(gong)控主(zhu)板(ban)(ban)比商(shang)用(yong)(yong)主(zhu)板(ban)(ban)成本(ben)價格(ge)高(gao)的(de)(de)(de)(de)(de)原因(yin)之一。隨著國產(chan)固(gu)態(tai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)器廠家越(yue)來越(yue)多,固(gu)態(tai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)器的(de)(de)(de)(de)(de)價格(ge)的(de)(de)(de)(de)(de)下(xia)降,現在(zai)的(de)(de)(de)(de)(de)高(gao)檔(dang)次(ci)的(de)(de)(de)(de)(de)商(shang)用(yong)(yong)主(zhu)板(ban)(ban)都(dou)在(zai)使(shi)用(yong)(yong)固(gu)態(tai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)器。
3)工控主板的PCB
商用(yong)主(zhu)(zhu)板(ban)(ban)采用(yong)的是4層(ceng)(ceng)PCB設(she)計(ji),一般的PCB線路板(ban)(ban)分有四(si)層(ceng)(ceng),最(zui)上和最(zui)下的兩(liang)層(ceng)(ceng)是信號層(ceng)(ceng),中(zhong)間兩(liang)層(ceng)(ceng)是接地(di)層(ceng)(ceng)和電源層(ceng)(ceng),將接地(di)和電源層(ceng)(ceng)放在中(zhong)間。工業主(zhu)(zhu)板(ban)(ban)采用(yong)的是6層(ceng)(ceng)以上PCB線路板(ban)(ban)設(she)計(ji),其設(she)計(ji)是為了加(jia)強(qiang)主(zhu)(zhu)板(ban)(ban)的抗(kang)電磁(ci)干擾(rao)、電磁(ci)兼容能(neng)力(li),增強(qiang)主(zhu)(zhu)板(ban)(ban)的穩定性等等。
4)工控主板的壽命
與商用(yong)主板(ban)2到3年(nian)使(shi)用(yong)壽命不同(tong),大多數的工(gong)控主板(ban)壽命要求(qiu)在3年(nian)以(yi)上,部分高品(pin)質(zhi)的工(gong)控主板(ban),使(shi)用(yong)壽命甚至達到5—7年(nian)。
一、保護功能
商用主板沒有提供的任(ren)何(he)的保護(hu)功能(neng);
工控主板通過特殊設計,在遇到死機等(deng)異(yi)常情況,可以實現看(kan)門(men)狗自動重(zhong)新啟動、防浪涌沖(chong)擊(ji)等(deng)功能(neng),全力的(de)保(bao)證(zheng)系統在惡劣環境的(de)高穩定性(xing)的(de)要求。

3)工控主板的PCB
商用(yong)主(zhu)(zhu)板(ban)(ban)采用(yong)的是4層(ceng)(ceng)PCB設(she)計(ji),一般的PCB線路板(ban)(ban)分有四(si)層(ceng)(ceng),最(zui)上和最(zui)下的兩(liang)層(ceng)(ceng)是信號層(ceng)(ceng),中(zhong)間兩(liang)層(ceng)(ceng)是接地(di)層(ceng)(ceng)和電源層(ceng)(ceng),將接地(di)和電源層(ceng)(ceng)放在中(zhong)間。工業主(zhu)(zhu)板(ban)(ban)采用(yong)的是6層(ceng)(ceng)以上PCB線路板(ban)(ban)設(she)計(ji),其設(she)計(ji)是為了加(jia)強(qiang)主(zhu)(zhu)板(ban)(ban)的抗(kang)電磁(ci)干擾(rao)、電磁(ci)兼容能(neng)力(li),增強(qiang)主(zhu)(zhu)板(ban)(ban)的穩定性等等。
4)工控主板的壽命
