11、干擾造成的故障
干擾造成的故障的實例也不少。系統(tǒng)的干擾信號可能來自于系統(tǒng)本身,也可能來自于外部環(huán)境。由于不同的系統(tǒng)對接地都有嚴格要求的規(guī)定,一旦接地電阻或接地方式達不到要求,就會使網路通信的效率降低或增加誤碼的可能,輕則造成部分功能不正常,重則導致網絡癱瘓。 電源質量同樣影響系統(tǒng)的穩(wěn)定運行。用于系統(tǒng)的電源既要保證電壓的穩(wěn)定,也要保證在一路電源故障時,無擾切換至另一路電源,否則會對系統(tǒng)工作產生干擾。過程控制處理機主/備處理機之間的切換有時也會導致干擾。另外,大功率的無線電通信設備如手機、對講機等在工作時,極易造成干擾,危及系統(tǒng)運行。
根據以往的DCS使用檢修維護管理經驗,總結了DCS常見故障,希望可以幫助更多在DCS維護方面欠缺的儀表人。
