基于MIMU的输电线路运动监测技术
Monitoring Technology of Transmission LineMovement Based on MIMU
摘要
Abstract
On the base of the transmission line movement monitoring techniques presently,a monitoring technology of transmission line movement base on MIMU is presented. The signals of MIMU are collected and establish ARMA model of MIMU time series and the data signals are processed by Kalman filter;and then treat the sum of squares of each axis specific force and the squares of angular velocity as a standard to measure the amplitude of the transmission line vertical motion and rotation, then the processed data is putted into different segments, through monitoring the euclidean similarity between data segments to measure the the magnitude of the transmission line vertical motion and rotation,motion frequency is obtained by FFT of acceleration and angular velocity data. Three different magnitudes movement of transmission line were simulated by the swings of turntable and the data was collected and processed by the algorithm above. The results show that the estimated vertical motion and rotational amplitude trends are the same as true amplitude. The simulation system can work properly under the laboratory conditions.关键词
