DEBRIS FLOW DETECTOR, RECEIVER AND DEBRIS FLOW DETECTION SYSTEM
To provide a debris flow detector that is able to detect an occurrence of a debris flow highly accurately and at a low cost.SOLUTION: One aspect of the present invention relates to a debris flow detector that comprises: a detection unit that detects vibrations including a ground vibration of a target place to be subjected to debris flow detection; a first determination unit that obtains and extracts an amount of feature from a waveform of the vibration detected by the detection unit and, based on the extracted amount of feature, determines whether an abnormal phenomenon has been occurring; a second determination unit that, in a case where the first determination unit determines that the abnormal phenomenon has been occurring, determines, through a mechanical learning model that has learned, whether the extracted amount of feature is caused by the occurrence of the debris flow; and a communication unit that communicates the occurrence of the debris flow.SELECTED DRAWING: Figure 5
【課題】土石流の発生を高い精度で検知可能であると共に、低コストで実現可能な土石流検知装置を提供することである。【解決手段】本発明の一態様は、土石流を検知する対象箇所の地振動を含む振動を検知する検知部と、前記検知部からの振動波形から特徴量を求めて抽出を行い、その抽出した特徴量に基づいて異常現象が発生しているかを判定する第１の判定部と、前記第１の判定部が前記異常現象が発生していると判定した場合に、学習済み機械学習モデルによって、前記抽出した特徴量が土石流の発生によるものであるかを判定する第２の判定部と、前記土石流の発生を通知する通信部と、を備える土石流検知装置に関する。【選択図】図５
