Title
(EN) DEVICE FOR MEASURING DISPLACEMENT OF STRUCTURE
(FR) DISPOSITIF DE MESURE DU DÉPLACEMENT D'UNE STRUCTURE
(JA) 構造物の変位計測装置
Abstract
(EN)
The present invention comprises: an acquisition means that acquires, along a time series, the degree of displacement of a structure as produced at a measurement location due to the weight of vehicles traveling on the structure; a detection means that detects the sizes of the vehicles passing over the structure and detects the types of vehicles from the sizes; and a control means that controls the acquisition means on the basis of the detected types of vehicles.
(FR)
La présente invention comprend : un moyen d'acquisition qui acquiert, le long d'une série chronologique, le degré de déplacement d'une structure telle que produite à un emplacement de mesure en raison du poids de véhicules se déplaçant sur la structure; un moyen de détection qui détecte les tailles des véhicules passant sur la structure et détecte les types de véhicules à partir des tailles; et un moyen de commande qui commande les moyens d'acquisition sur la base des types de véhicules détectés.
(JA)
構造物を走行する車両の重量によって構造物の計測箇所に生じる変位量を時系列に沿って取得する取得手段と、構造物を通過する車両の大きさを検出し、上記大きさから車両の種別を検出する検出手段と、検出された車両の種別に基づいて、取得手段を制御する制御手段と、を備える。
