摘要
随着石油勘探的发展,在地震勘探仪器中越来越需要高精度的同步技术来支持高效采集。基于这种目的,采用FPGA技术设计了一种时钟恢复以及系统同步方案,并完成了系统的固件和嵌入式软件设计。通过室内测试、野外试验以及生产应用,证明结合FPGA技术,时钟恢复和系统同步技术在地震勘探仪器中具有独到的优势,其精度可达us级,而且稳定,实现方便。
With the development of petroleum prospecting, it requests higher synchronization accuracy for high efficiency acquisition with seismic instrument. So we design a solution of CDR and system synchronization implementation with FPGA to meet this requirement, and we also finished the firmware and embedded software. By room and field test, it shows that this solution has a good performance with FPGA technology. It has high accurate, better than one microsecond, and it is stable, easy to match our requirements.
