ABNORMALITY DETERMINATION METHOD AND ABNORMALITY DETERMINATION PROGRAM

To provide an abnormality determination method which can determine not only an abnormality in a current collecting device but also an abnormality in an overhead power line by monitoring the state of the current collecting device.SOLUTION: An abnormality determination method according to an embodiment of the present disclosure acquires an output value of each line separation sensor corresponding to each of a plurality of current collecting devices, calculates a line separation rate for each travel section of each current collecting device on the basis of the output value, determines whether or not there is an abnormality in the current collecting device being the determination object on the basis of a difference between a travel section reference line separation rate preset for each travel section and the line separation rate in each travel section of the current collecting device being the determination object, and determines whether or not there is an abnormality in an overhead power line in the travel section being the determination object on the basis of the difference between the current collecting device reference line separation rate preset for each current collecting device and the line separation rate in each current collecting device in the travel section being the determination object.SELECTED DRAWING: Figure 2 【課題】集電装置の状態を監視することで、集電装置のみならず架線の異常も判定できる異常判定方法を提供する。【解決手段】本開示の一態様に係る異常判定方法は、複数の集電装置のそれぞれに対応する各離線センサの出力値を取得し、前記出力値に基づいて各集電装置の走行区間ごとの離線率を算出し、走行区間ごとに予め設定した走行区間基準離線率と判定対象の集電装置の各走行区間における離線率との差分に基づいて、判定対象の集電装置に異常があるか否かを判定するとともに、集電装置ごとに予め設定した集電装置基準離線率と判定対象の走行区間の各集電装置における離線率との差分に基づいて、判定対象の走行区間の架線に異常があるか否かを判定する。【選択図】図２
