道路路面异常点收集系统及道路路面异常点收集方法;SYSTEM AND METHOD OF COLLECTING ABNORMAL POINT OF ROAD SURFACE

摘要

一种道路路面异常点收集系统及其方法在此揭露。道路路面异常点收集方法包含：收集车辆行驶时之震动值，并据以取出垂直于路面之震动分量值；根据车辆开始行驶在固定时间内之震动分量值以计算出基准数值，进而计算平均震动变化范围；于多个单位时间中找出震动分量值有超过平均震动变化范围之所有部分震动分量值并计算出异常数值；计算异常数值与基准数值之比值以得出异常指标；传送异常指标至伺服器。; calculating a reference value according to the vibration component value collected within a fixed interval when the car is started driving and further calculating an average vibration variation range; finding all parts of the vibration component value that is over the average vibration variation range within the unit intervals and calculating an abnormal value according the part of the vibration component value; calculating an abnormal index that is the ratio of the abnormal value to the reference value; and transmitting the abnormal index to a server.
