摘　　要：采用PCL-812PG多功能数据采集卡,在Visual C++平台上开发出液位/流量数据采集和实时控制系统。介绍了数据采集测试软件和系统实时控制软件的设计与实现。为确保实时性和控制精度,系统使用了多媒体定时器。设计的软件经实验装置检验,可以满足设备实时控制要求。Tile PCL- 812PG multi-lab card is used to form a flow/level data acquisition and real-time control system based on the Visual C ＋ ＋ . The software design and realization of a test and control system is presented in the paper. A multimedia timer is used to ensure the control accuracy and the real - time property. The results show that the software system can satisfy the real-time control required by the equipment.
