基于IPC的数控测井系统升级技术研究

针对目前在国内占主流地位的“小数控”测井装备大多采用PC机ISA总线和DOS、Windows9x作为系统的硬、软件支撑环境,提出了采用PCI局部总线和Windows2000的硬、软件升级方案。介绍了PCI的性能指标、主要概念、接口芯片和在研发中可能面临的主要问题,并给出了针对高性能测井系统要求的PCI接口卡功能分配方案。讨论了Windows2000操作系统的先进性能和在数控测井系统中应用的依据,并对应用程序开发中的关键环节———内核设备驱动程序的基本概念、编程工具、设计方法要点以及针对PCI总线即插即用驱动器接口设计作出了相应说明。随着IT技术的不断发展,这种技术升级方案可以满足今后石油行业所有测井设备对系统环境的要求,包括组成高端的成像测井系统。

UPGRADING TECHNOLOGY OF DIGITAL CONTROL LOGGING SYSTEM BASED ON IPC

With respect to most of the 'mini' well logging equipment using the ISA bus of PC and DOS/Windows9x as hardware and software supporting environment,a scheme for upgrading the hardware and software using PCI local bus and Windows2000 was proposed.The background,specifications,interface chips,main concepts and possible problems faced in research and development of PCI were introduced.Moreover,a scheme for function assigning of PCI card for the high performance logging system was given.The advantage and bankground of Windows2000 operation system applied in digital control well logging system were discussed.The gist in application program development,such as kernel device driver programming,programming tools,designing methods and PNP device driver interface for PCI bus were illustrated.With development of the IT,the scheme proposed in this paper may meet the needs of logging equipment in the future,including the high performance image logging system.
