摘　　要：针对高压输电塔线体系风致振动研究现状和面临的问题,设计并实现了一款可对风速信号和位移信号进行采集和处理的低频振动采集分析仪。设计了一种基于时差的三维风速算法对风速信号进行处理,与传统的二维风速处理结果相比较,其处理结果更可靠。另外,该分析仪还实现了对风速信号、位移信号的频谱、功率谱分析,并且支持远程Web控制。经过实验和分析发现,该分析仪风速测量精度可达到0.01 m/s。Aiming at the present situation and the problems of wind induced vibration in high voltage transmission tower sys-tem,this paper designed and realized a low frequency vibration acquisition analyzer which can collect and process wind speed sig-nal and displacement signal.The three-dimensional wind speed algorithm based on time difference was designed to deal with thewind speed signal.Compared with the traditional two-dimensional wind speed processing,the processing result was more reliable.In addition,the analyzer also implemented spectrum analysis and power spectrum analysis of wind speed signals,displacement sig-nals,and supported remote Web control.Experiments and analysis found that the wind speed measurement accuracy of the analyzercan reach 0.01 m/ s.
