Research on the Multi-Channel Surface Wave Data Acquisition for Seismic Exploration Based on ADS1258
the technology of surface wave data acquisition acquires the surface wave data efficiently.ADS1258 serves as the AD conversion chip,Altium Designer 9.0 is used as the development tool and the hardware description language (VHDL)is applied to control the application of various hardware modules.The specific design content of the hardware is to connect the original surface wave signals acquired by 16 channels to AD8253circuit,the software programming is used to control the amplification factor of control signal,and then input the 16-channel signals amplified to ADS1258 AD converter in order to convert the analog signals into digital signals.3 pieces of ADS1258 are used in the detector;totally 48 channels of data are acquired.Finally,using SPI bus protocol to control the normal work,so that the hardware acquisition board can achieve its optimal working condition.
