所謂自動檢測，是指由計(jì)算機(jī)進(jìn)行控制對系統(tǒng)、設(shè)備和部件進(jìn)行性能檢測和故障診斷，是性能檢測、連續(xù)監(jiān)測、故障檢測和故障定位的總稱?，F(xiàn)代自動檢測技術(shù)是計(jì)算機(jī)技術(shù)、微電子技術(shù)、信息論、控制論、測量技術(shù)、傳感技術(shù)等學(xué)科發(fā)展的產(chǎn)物，是這些學(xué)科在解決系統(tǒng)、設(shè)備、部件性能檢測和故障診斷的技術(shù)問題中相結(jié)合的產(chǎn)物。凡是需要進(jìn)行性能測試和故障診斷的系統(tǒng)、設(shè)備、部件，均可以采用自動檢測技術(shù)，它既適用于電系統(tǒng)也適用于非電系統(tǒng)。電子設(shè)備的自動檢測與機(jī)械設(shè)備的自動檢測在基本原理上是一樣的，均采用計(jì)算機(jī)/微處理器作控制器通過測試軟件完成對性能數(shù)據(jù)的采集、變換、處理、顯示/告警等操作程序，而達(dá)到對系統(tǒng)性能的測試和故障診斷的目的。
