摘　　要：三维传感器有激活阈值参数,达到该参数时,可触发采集加速度数据;船舶的运行状态与三维加速度有密切联系;支持向量机是一种监督分类方法,学习三维加速度对应的船舶状态,再通过支持向量机学习参数,识别船舶的运动状态以及修正三维传感器激活阈值,可以达到记录运动轨迹的目的,减少不必要的GPS、北斗定位,实现系统的节能降耗及航程记录。The three dimensional sensor has an activation threshold parameter.When this parameter is reached,it can trigger the acquisition of acceleration data,the operating state of the ship is closely related to the three dimensional acceleration,the support vector machine is a supervised classification method.The vector machine learns the parameters,identifies the motion state of the ship and corrects the activation threshold of the three dimensional sensor,which can achieve the purpose of recording the motion trajectory,reduce unnecessary GPS and Beidou positioning,and realize the energy saving and voyage recording of the system.
