摘要
谱烈度传感器采用三分量MEMS器件采集加速度信号,经过IIR带通滤波器,采用一种地震动谱烈度的实时计算方法,根据单自由度系统的地震输入响应,利用Z变换方法,得到相对速度反应谱的差分方程,来计算实时地震动谱烈度。
Spectrum intensity sensor collects acceleration signal by using three components MEMS device, by IIR band-pass filter, adopt a real-time calculation method of ground vibration spectrum intensity, according to earthquake input response of single degree of freedom （SDOF） system, use z-transformation method, difference equation of relative velocity response spectrum is deduced, realtime groun vibrmtion spectrum intensity is calculated.
