ROAD SURFACE INSPECTION SYSTEM AND ROAD SURFACE INSPECTION METHOD
PROBLEM TO BE SOLVED: To easily measure an index of an accurate road surface independently of a measurement condition of an installation position or the like of an acceleration sensor in a road surface inspection system using the acceleration sensor.SOLUTION: A measurement device removably installed in a vehicle acquires a measurement condition and stores it into a first storage unit, measures vibration data of the vehicle during travel using a vibration measurement unit, measures position data of the vehicle using a position measurement unit and stores the vibration data and the position data into the first storage unit. A computer for calculating an index accepts the measurement condition, the vibration data, and the position data stored in the first storage unit and converts the vibration data into an acceleration displacement of sprung mass of a vibration model and converts the acceleration displacement of sprung mass into the index and stores the index and the position data into a second storage unit in association with each other.
【課題】加速度センサを用いた路面点検システムに関して、加速度センサの設置位置等の測定条件によらず、正確な路面の指標を容易に測定することを目的とする。【解決手段】脱着自在に車両へ設置された測定装置が測定条件を取得して第１の記憶部へ格納し、測定装置が、走行中の前記車両の振動データを振動測定部で測定し、車両の位置データを位置測定部で測定し、振動データと位置データを前記第１の記憶部へ格納し、前記指標を演算する計算機が、第１の記憶部に格納された測定条件と振動データ及び位置データを受け付け、振動データを振動モデルのばね上質量の加速度変位に変換し、ばね上質量の加速度変位を前記指標に変換し、前記指標と位置データを対応付けて第２の記憶部へ格納する。【選択図】図１
