To provide a novel technique capable of determining the presence/absence of occurrence of abnormality in a switch machine.SOLUTION: A switch machine state monitoring device 1 detects operation sound of a control relay 34 from an analysis result of acoustic data acquired by an acoustic sensor 5 installed in a housing of a switch machine 3 and specifies a switching operation period of the switch machine 3 in the acoustic data. The changeover operation period is divided into an unlocking step, a switching step, and a locking step. The presence/absence of occurrence of an abnormality in the switch machine 3 is determined for each step created by dividing the switching operation period based on the analysis result of the acoustic data determined to be normal in the past and an analysis result this time.SELECTED DRAWING: Figure 1
【課題】転てつ機の異常発生の有無の判定を可能とする新たな技術を提供すること。【解決手段】転てつ機状態監視装置1は、転てつ機3の筐体内に設置された音響センサ5により取得された音響データの解析結果から制御リレー34の動作音を検出して、音響データにおける転てつ機3の転換動作期間を特定する。また、転換動作期間を、解錠工程、転換工程及び鎖錠工程に区分する。そして、過去に異常無しと判定した音響データの解析結果と今回の解析結果とに基づいて、転換動作期間を区分した各工程毎に転てつ機3の異常発生の有無を判定する。【選択図】図1
