The paper introduces the designing method of the industrial control system software in Windows by Visual C++, displaying the using of the Timer, interacting of man and machine, bitmap. 系统的介绍了Windows操作系统下用Visualc++编制工控软件的实现方法,说明了定时器、人机交互、位图等在工控软件的作用。
A computer automatic test system is introduced, which by using Industrial Control PC and Multifunction Data-acquisition Card PCL-818L and PCL-836 Multifunction Counter/ timer Card, which can reflect the process of change in real-time. 介绍了由工控机、多功能数据采集卡PCL-818L和PCL-836多功能计数器/定时器卡组成的一套计算机自动测试系统。
The incremental PID algorithm is applied in the electro-hydraulic servo valve control system to achieve accurate control, and the industrial PC ( IPC), Counter/ Timer and D/ A module are adopted in the hardware design. 通过利用增量式PID控制方法,采用工业控制计算机、计数器/定时器及数模转换器,实现了对电液伺服阀的准确控制。
