A High Performance Data Readout System Design for Marine Multi-channel Seismic Exploration
【摘要】 介绍了一种用于海洋地震勘探的高性能、多通道数据读出系统,该系统基于先进的Compact PCI平台,由拖缆数据读出和预处理插件、系统同步插件以及数据汇聚传输插件组成,各模块之间通过高速背板总线进行数据交互,并通过千兆以太网将数据传输至数据获取系统。实验室测试和海上作业实验表明,本读出系统架构合理、配置灵活、工作可靠,能够完成高精度三维海洋地震勘探对读出系统的实时处理和传输的要求。
【Abstract】 A high performance data readout system is proposed for marine multi-channel seismic exploration.This readout system is designed and implemented based on the advanced Compact PCI architecture.It is composed of cable data readout and pre-processing,system synchronous module and data concentration module.These modules are connected together through the high speed backplane bus of Compact PCI crate.The concentrated seismic data are sent to the data acquisition system via Gigabit Ethernet.Lab and in-situ experiments and tests show that exploration equipment with this readout system has advantages of good architecture,resilient configuration and reliability.It can fulfill the requirements of data real-time processing and transmission for 3D marine seismic exploring.
