中文摘要：
基于软硬件技术,设计了一种用于地下爆破震动信号检测及处理的系统。系统硬件部分由传感器、存储器、USB等部件组成,负责采集原始震动信号。软件部分设计了以LabWindows/CVI为平台的虚拟示波器,不仅具有传统示波器的功能,还可实现对震动信号不同方向轴分量的合成、滤波和提取震动信号初至波时间等。实验结果表明,该系统工作稳定可靠、操作简单,能够对震动信号进行检测、处理和显示。
英文摘要：
In order to detect and process underground vibration signal, this paper presents a system with the combination of software and hardware. The hardware part consists of sensor, memory chips, USB, etc. , which is responsible for capturing original signals from sensors. The software part is a virtual oscilloscope based on LabWindows/CVI （C vitual instrument）, which not only has the functions of traditional oscilloscope but also can analyze and process vibration signals in special ways. The experimental results show that the designed system is stable, reliable and easy to be operated, which can meet practical requirements.
