基于九轴传感器监测导线舞动的研究方法

Monitoring Galloping of Transmission Lines Based on Nine-Axis Sensors

摘要: 本文设计提出用九轴传感器(加速度计 + 磁力计 + 陀螺仪)测量导线舞动的扭转和平动的架构，得到完全的监测信息，克服传统只用加速度计监测导线舞动只能得到位移的缺陷。并且我们用仿真实验证明，传统的只用三轴加速度计的监测算法，在扭转比较大时会得到错误的位移估计结果，而九轴算法则可以避免这种错误。由此证明在普遍存在扭转的导线舞动监测的实际应用中，九轴架构相比于传统三轴加速度计算法存在巨大的优势。

Abstract: This paper designs the architecture using nine-axis sensors (accelerometer, magnetometer, and gyroscope) to monitor the galloping of transmission lines, which can get full information of galloping including position and rotation, and overcome the shortcomings of traditional method; namely using accelerometer alone we can only get the position of the measured point. We show that the traditional method may get wrong result without considering the rotation involved using simulation platform, and using nine-axis algorithm we can avoid this. Thus we show the great ad-vantages of nine-axis algorithm compared to traditional method.
