基于上位机的数据采集程序的设计

针对目前监控软件的数据归档周期无法满足某些数据采集的要求，提出了一种基于上位机的数据采集方法，介绍了工具箱函数的调用和多媒体定时器的使用。实际使用证明该方法可行。

The Design of a Data Acquisition Program Based on Upper Station

According to the problem that the data archiving period of the monitoring software can't meet the data acquisition's demand,this paper presents a data acquisition method based on upper station.The MPI communication is built between the upper station and the lower station,the PRODAVE toolbox is used to read the data of the lower station.The multimedia timer is used in the upper station to meet the speed and timing accuracy demand of the data acquisition,and the application of the toolbox and the multimedia t...
