          對轉轍器進行遠程監控,通過監控數據準確診斷早期故障并完成故障定位,為軌旁設備整體維修維護提供決策支持,最終達到降低系統風險,并降低系統維修維護費用的目的,從而達到安全性和經濟性的平衡點。

          轉轍器由幾大核心部件組成,包括電機、定位桿、固定軌、移動軌、驅動桿等,精確的故障診斷和定位有助于維修維護團隊準確及時的解決問題。常見的故障模式包括不對準、摩擦力上升、有異物等。

          圖2轉轍器示例[3]

          對關鍵設備的早期故障診斷及故障定位,核心在于發現或者創造相應的故障特征。故障特征可以是原始信號,也可以是由原始信號加工得到。主要運用技術包括數字信號處理、特征選擇、降維、時間序列分析、以及多變量狀態估計等。在實際系統構架當中,各種技術需要搭配使用,相輔相成,最終實現目的。

          如下圖所示,從原始信號中,例如電機電壓、電流、扭矩等,得到的特征應該在設備性能發生衰退時呈現出逐漸偏移的趨勢,并且偏移的速率與衰退的速率成正比。當然,這是理想狀態下的完美特征,也是無數工業數據分析工作者的完美伴侶。在通常情況下,受制于原始信號的完整性,以及工作環境的變化等,這樣的完美伴侶總是如“戈多”一樣的可遇而不可求。
