虚拟仪器在声波激发的地表振动检测系统中的应用
|
摘要
设计一个声波激发的地表振动检测系统,用基于Labview的软件平台实现数据的采集与处理。用扬声器发出扫频的正弦声波激励地表产生地表振动,并用地震检波器接收地表振动速度信号,通过NI 5112数字化仪传送到计算机,在Labview环境下进行滤波、频谱分析、波形显示与数据存储等处理。实验结果显示,该系统能有效完成测量任务,可用于声-地震耦合现象的进一步研究。
An experimental system for acoustic-to-seismic coupling is developed.Labview software development plat-form is used to conduct data acquisition and processing.Seismic waves are induced by using a loudspeaker to generate a swept sine tone to the ground surface.The vibration velocity of the ground surface is received by a geophone,and sent to a computer via NI-5112 digitizer.Functions of filtering,spectrum analysis,waveform display and data storage are performed with Labview.The results indicate that the presented system can realize the test efficiently and can be used for further experimental study of acoustic-to-seismic coupling.
