To prevent a device from getting out of order while saving the trouble, concerned with setting work used for abnormality diagnosis on a component of a moving body, in the abnormality diagnosis.SOLUTION: An abnormality diagnosis system comprises: a state sensor which acquires state information on a component constituting a moving body; a position sensor which acquires position information on the moving body; a setting part which sets, based upon the state information on the component when the moving body is located in a predetermined section, an initial value for the state information on the component and a threshold for a quantity of change from the initial value; and a diagnosis part which performs, when detecting the moving body being located in the predetermined section based upon the position information acquired by the position sensor, abnormality diagnosis on the component from whether the difference between the initial value and the state information acquired by the state sensor exceeds the predetermined threshold.SELECTED DRAWING: Figure 1

    【課題】移動体の構成部品に対する異常診断において、異常診断に用いられる設定作業に係る手間を低減しつつ、装置の故障を未然に防ぐ。【解決手段】異常診断システムであって、移動体を構成する構成部品の状態情報を取得する状態センサと、前記移動体の位置情報を取得する位置センサと、前記移動体が所定の区間に位置した際の前記構成部品の状態情報に基づいて、前記構成部品の状態情報に対する初期値と、当該初期値からの変化量に対する閾値を設定する設定部と、前記位置センサにて取得される位置情報に基づいて前記移動体が前記所定の区間に位置したことを検知した際に、前記初期値と前記状態センサにて取得される状態情報との差分が前記所定の閾値を超えるか否かにより前記構成部品の異常診断を行う診断部とを備える。【選択図】図1
