Time Pulse Interpolation Analysis Method for Data Acquisition Test
The time service accuracy of the seismic data acquisition device is an important index to evaluate the performance of equip-ment.Standard time pulse signals are generally used for testing,but the low sampling rate of the instrument limits the resolution of time error testing.The algorithms of pulse signal rising edge identification,high and low potential calculation and time deviation analysis are designed,and the waveform upsampling recovery of standard time pulse signal collected by seismic data acquisition device is studied by using nonlinear interpolation analysis method,and experimental analysis and discussion are carried out based on the proposed algorithms.Therefore,the resolution of time deviation test of seismic data acquisition device is improved,and the test data processing method and process are standardized.
