Abstract :
In view of the underground vibration signals with characteristics of mutation, fast attenuation and so on, a testing data processing system was designed and based on LabWindows/CVI. System was designed by the reasonable allocation of software and hardware, hardware part consists of sensor, memory, USB and other parts. Software p art is virtual oscilloscope based on LabWindows/CVI, not only has the function of traditional oscilloscope, but can compound, filter the different direction signals, extract the first break time of the signal and so on. The system uses LabWindows/CVI the strong signal processing function of LabWindows/CVI, realized the design of vibration testing data processing system. Experimental verification, the system was stable and reliable, operation is simple, convenient maintenance, has reached the expected goal.
