工(gong)(gong)控主板(ban)是應用(yong)于工(gong)(gong)業場(chang)合的主板(ban),被工(gong)(gong)業電腦所采用(yong),根據(ju)需(xu)求可(ke)(ke)以適(shi)應寬溫環境(jing)(jing),可(ke)(ke)以適(shi)應惡劣環境(jing)(jing),可(ke)(ke)以長時(shi)間高負荷工(gong)(gong)作等。工(gong)(gong)控主板(ban)是嵌入(ru)式(shi),低功(gong)耗,耐低溫-20度、耐高溫70度,防(fang)干擾。
工控主(zhu)板(ban)元(yuan)器(qi)件:主(zhu)板(ban)的元(yuan)器(qi)件需要適應寬溫環境(jing)(jing)(-20℃~60℃),保(bao)證在惡(e)劣環境(jing)(jing)下(壽命(ming)期內永久開機(ji)、氣候惡(e)劣、潮濕、振動(dong)、多塵(chen)、輻射、高溫等等)正(zheng)常工作。主(zhu)板(ban)元(yuan)器(qi)件需要耐(nai)高溫、抗潮濕等等。高質量的貼片式(shi)的電(dian)(dian)解、鉭(tan)、陶(tao)瓷電(dian)(dian)容(rong)。
工控主板的PCB(線路布(bu)局(ju)):商用(yong)主板采(cai)用(yong)的是4層(ceng)(ceng)(ceng)PCB設(she)計,一(yi)般的PCB線路板分有四層(ceng)(ceng)(ceng),最上和(he)最下(xia)的兩(liang)層(ceng)(ceng)(ceng)是信(xin)號層(ceng)(ceng)(ceng),中(zhong)間(jian)(jian)兩(liang)層(ceng)(ceng)(ceng)是接地層(ceng)(ceng)(ceng)和(he)電(dian)(dian)源層(ceng)(ceng)(ceng),將(jiang)接地和(he)電(dian)(dian)源層(ceng)(ceng)(ceng)放在中(zhong)間(jian)(jian)。工控主板采(cai)用(yong)的是6層(ceng)(ceng)(ceng)以(yi)上PCB線路板設(she)計,其(qi)設(she)計是為了加(jia)強(qiang)工控主板(ban)的(de)抗電(dian)磁干擾、電(dian)磁兼容能力,增強主板的(de)穩定性等(deng)等(deng)配置信息。
CPU:工控(kong)(kong)主板一般選(xuan)用的(de)(de)是低功耗(hao)的(de)(de)CPU,以便適應工控(kong)(kong)行業惡(e)劣的(de)(de)環境應用,部分功能(neng)整合(he)在(zai)處理器上的(de)(de)CPU抗電(dian)磁波干(gan)擾能(neng)力(li)不同:對抗電(dian)磁波干(gan)擾能(neng)力(li)要求較高,需要通過EMI、EMC等測(ce)試和(he)認證。
工(gong)(gong)控(kong)(kong)(kong)(kong)主板(ban)主要(yao)應用:工(gong)(gong)控(kong)(kong)(kong)(kong)設備(bei),GPS導(dao)航、污水在(zai)(zai)線監控(kong)(kong)(kong)(kong)、空氣在(zai)(zai)線監測、儀(yi)器儀(yi)表(biao),專業設備(bei)控(kong)(kong)(kong)(kong)制器,軍工(gong)(gong),政府機關、電(dian)信(xin)、銀(yin)行、電(dian)力、車載(zai)液(ye)晶(jing),監視器,可(ke)視門鈴,便(bian)攜DVD,液(ye)晶(jing)電(dian)視、環保(bao)設備(bei)等(deng)。
