At present the identification signal of rolling bearing is based on analog monitoring system composed of analog instrument such as fft analyzer , amplitude analyzer and so on . the system has the shortcoming as follows : not enough friendly user interface , unitary function , under abundant analytical contents , poor generality , long developing period , high cost and so forth 目前對滾動軸承信號識別主要采用模擬監(jiān)測系統(tǒng),系統(tǒng)均由模擬量儀器組成,如fft分析儀、幅值分析儀電平記錄儀等,系統(tǒng)存在操作界面不夠友好,功能單一,分析內(nèi)容欠豐富、通用性差、開發(fā)周期長、成本高等缺點。
