摘要
为解决EILog测井系统采集箱体硬件升级后ACME采集前端软件与硬件的匹配问题,对精确延时和采集卡中断管理进行研究。分析问题产生的原因,介绍硬延时和PCI配置头的原理和工作流程,阐述问题的解决方案并给出了具体实现方法。改进升级后的前端软件完全适应EILog新旧采集硬件在不同情况下的应用,可保证EILog测井系统采集获取到正确的井下数据。
ACME acquisition front-end software and hardware matching becomes an urgent problem with upgrading of the EILog well logging system acquisition cabinet hardware. In this paper we focus on two key issues encountered during the system upgrade process：accurate delay and capture card interrupt management. We analyze the causes of this problem, and briefly introduce the principle and workflow of the hard delay and PCI configuration header, and give the solution of implementation method on specific problem. The good adaptability has been proved between upgraded front-end software and old and new EILog system acquisition hardwares in different cases and the logging data accuracy is guaranteed.
