Train Running Slope Measurement Device Based on Multi-accelerometer Fusion Algorithm

提出一种基于多加速度计融合的列车运行坡度测量装置。该装置通过不同角度的加速度计来测量列车的实时加速度,结合加速度计融合算法,可动态计算出列车所在位置的线路坡度值。该方法使得列车不依赖于精确定位和电子地图就可进行超速防护,提升了安全性和可用性,有利于推广应用到互联互通CBTC(基于通信的列车控制)系统中。

A train running slope measurement device based on multi-accelerometer fusion is proposed.The system measures the real-time acceleration of the train through accelerometers of different angles,and combined with the accelerometer fusion algorithm,the slope value of the train position can be dynamically calculated.By using this method,the train does not rely on precise positioning and electronic map for overspeed protection,which improves the security and availability of the system,and is beneficial for popularizing and being integrated into the interoperable CBTC system.
