摘要
提出一种基于LabVIEW地震动信号采集的方法,该系统将采集的地震动信号,经硬件电路放大、滤波,再由LabVIEW对输出信号进行实时采集与显示。通过电路设计、仿真及外场实验测试,实现了系统验证。试验结果表明,该系统功耗低,测量精度高,界面友好,在国防、民用领域的多种场合均可起到预警作用,有广泛的应用前景和重大的现实意义。
Presents a method to acquire vibration signal based on LabVIEW.The system collects the vibration signal,amplify and filter it by hardware circuit,then acquire and display the output signal by the LabVIEW in real time.Through the circuit design,simulation and field test,realize the system verification.The result of experiments shows that the system has low power consumption,high measuring precision and friendly interface.It plays an early warning role in a variety of occasions such as the defence and residential areas,and has wide application foreground and important practical significance.
