To estimate the mass of a hoisted load of a hoisting machine highly accurately.SOLUTION: A hoisting machine for moving a hoisted load in the vertical direction, includes an operation information acquisition unit for acquiring operation information of the hoisting machine and a hoisted load mass estimation unit for estimating the mass of a hoisted load of the hoisting machine from the operation information acquired by the operation information acquisition unit. The hoisted load mass estimation unit estimates the mass of the hoisted load according to a hoisted load mass estimation formula learned in advance by using data associated with the operation information and the mass of the hoisted load. Accordingly, it is possible to estimate the mass of the hoisted load reflecting behavior in the real world that cannot be modeled by the model-based method so that the mass of the hoisted load of the hoisting machine can be estimated highly accurately.SELECTED DRAWING: Figure 2

    【課題】巻上機の吊荷質量を高精度に推定する。【解決手段】吊り下げた吊荷を鉛直方向に移動させる巻上機であって、前記巻上機の運転情報を取得する運転情報取得部と、前記運転情報取得部が取得した前記運転情報から前記巻上機の吊荷質量を推定する吊荷質量推定部と、を備え、前記吊荷質量推定部は、前記運転情報と前記吊荷質量が対応付けられたデータを用いて予め学習しておいた吊荷質量推定式に基づいて、前記吊荷質量を推定する。これにより、モデルベースの手法ではモデル化しきれない現実世界の挙動までも反映した吊荷質量の推定ができるため、巻上機の吊荷質量を高精度に推定することが可能となる。【選択図】図2
