|
摘要
针对地震勘探大数据量的采集要求,设计了一种基于双CPCI总线的地震数据采集接口卡。接口卡采用双CPCI总线结构,使用高性能的FPGA和DDR2 SDRAM进行数据处理和存储,实现地震数据的高速采集、预处理及CPCI总线传输等功能。重点介绍了双CPCI总线结构、存储器接口以及高速通信接口的设计和实现方案。海上生产应用结果表明,板卡满足海上地震勘探对接口卡的采集、处理和存储要求。
In order to meet the requirement of large amount of seismic data acquisition,a seismic data acquisition interface board based on dual CPCI bus is designed.The board is designed to double CPCI bus structure,and uses high performance FPGA and DDR2 SDRAM for data processing and storage.It can realize the function of high-speed acquisition,preprocessing and CPCI bus transmission of seismic data.The design and implementation of dual CPCI bus structure,memory and high speed communication are introduced.The application results show that the board can meet the requirements of acquisition,processing and storing in the marine seismic exploration.
