Development of a New Centralized Data Acquisition System for Seismic Exploration
Abstract. Seismic exploration equipment has developed rapidly over the past few decades. One such piece of equipment is a centralized seismograph, which plays an important role in engineering, so improving its performance is of great scientific significance. However, there is still a gap between seismic exploration equipment that is inde-pendently developed by China and that developed worldwide; this gap needs to be bridged via the advancements made in technology. In this research, the core part of general seismic data acquisition devices is packaged to develop a centralized seismic data acquisition system (Named as CUGB-CS48DAS) that has independent operating ability and high scalability, which can be used for engineering seismic and electrical prospecting. The low-power-consumption computer of the system comprises a 24-bit Σ-△ modulation A/D converter and 48 sampling channels with an optional sampling rate of 50 Hz to 64 KHz, crosstalk rejection ratio ≥ 80 dB, dynamic range ≥ 120 dB, frequency response range of DC to 16 KHz, synchronization accuracy better than 200 ns, and data transmission speed ≥ 90 Mbps. With regard to the host computer, the ar-chitecture of the control software is smart, and it can integrate the multiple functions of data acquisition, preprocessing, and self-testing; clear interfaces reduce the com-plexity of development and migration.
