Abstract：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.
Key words：LabVIEW；sensor；seismic signals；real-time acquisition
