摘要
提出了一种高精度、高性能的用于海洋地震勘探的拖缆数字包,并给出其设计与实现。每个数字包含有16个数据采集通道,每个通道都可以直接连接水听器,而水听器产生的模拟信号被由FPGA控制的24-bit高精度Δ-ΣADC实时采集。同时,基于串行并发总线结构,设计和实现了系统的实时控制和远距离数据传输与同步。测试结果表明:该拖缆数字包满足海洋地震勘探的要求。
A reliable high-precision and high-performance strea mer cable digitizer for marine seismic exploration is proposed.In the precise digitizer,there are total 16 data acquisition channels,each of which can be co nnected to hydrophones directly.Analog signals are digitized by 24-bit high pr ecise Δ-Σ ADCs controlled by field programmable gate array(FPGA) in real ti m e.Schemes of real time system control and remote synchronization are also well designed and realized in the digitizer based on the architecture of serial concu rrent bus which is implemented by FPGA.The results indicate that the digitizer can meet the requirements of marine seismic exploration.
