摘要
数据采集是过程监测与系统控制中极为关键的环节,其实时性能的好坏直接影响着控制系统的稳定性和动态性能。文章在分析设备驱动程序工作特点的基础上,提出了一种利用可安装的设备驱动程序,实现数据采集从DOS平台到Windows平台移植的方案,提高了Windows多任务操作系统下数据采集的实时性。
Data acquisition is very important in the process monitor and system control. Its real - time property directly affects the stability and the dynamic behavior of the system. The paper first analyses the working characteristics of device driver, and then puts forward a method that can transplant data acquisition program from DOS system to Windows system by using the installable device driver, thereby improving the real-time property of data acquisition in Windows multiple task operation system to some extent.
