摘要
针对以工业 PC为主机的现代测井系统 ,讨论了在 32 bits Windows操作系统下的有关设备驱动程序的设计技术。通过对操作系统实时处理性能的分析和对设备驱动程序基本概念的讨论 ,说明了基于 Win9x的 Vx D设计方案中所有与硬件控制有关的操作 ,对数据采集中的硬件中断处理方法有较为详细的叙述。所介绍的设计技术已经成功用于多种与石油测井有关的工业测控系统。
Aiming at the modern logging system with IPC as main computer, we discuss the technology in designing virtual device drivers based on 32 bits Windows operating system. By analyzing both the realtime processing performance of the operating system and the principle of the virtual device drivers, a VxD disign which controls all types of PC hardware based on Win9x and a processing method of data acquisition with an interruption is illustrated. The introduced technology has been successfully used in several industrial control systems for well logging.
