摘要
针对地震勘探仪器在多道数据并行采集控制技术上的瓶颈问题,提出基于嵌入式可编程片上系统的并行采集方案,开发了符合Avalon标准的"多道数据并行采集A/D组控制器"外设IP核,实现了多道数据严格并行采集控制,并成功应用在工程地震数据采集系统中。应用表明,该控制器能控制多道A/D转换器严格并行同步采样,具有同步精度高、非均匀误差小、通道扩展方便等优点,为地震勘探仪器高性能、低功耗、微型化设计提供了参考。
In order to solve the bottleneck of muhi-channel seismic data parallel acquisition control,this paper presented a parallel acquisition solutions which was based on embedded system on a programmable chip(SOPC),and developed the peripheral IP cores named "Parallel Multi-channel Data Acquisition A/D Group Controller" which met the Avalon standard. The controller had achieved strictly control of parallel muhi-channel conversion,and was ap- plied successfully in engineering seismic data acquisition system. Practical applications have shown that the controller has the characteristics of high synchronization accuracy,low non-uniform error and convenient to expansion.
