【摘要】 采用ActiveX技术设计数据采集与显示控件,搭建了硬件实验平台,提出了数据采集与显示控件的模块结构。该控件可对压力、温度、位置等进行检测和记录,并绘制成图形,从而方便地看出多个参数变化的关系,进而有助于提高控制精度。同时还可大大减少软件编制工作量,缩短软件开发周期。更多还原

【Abstract】 In this paper,the authors design a data collection and display control based on ActiveX technology.They es-tablish a hardware experiment system,put forward the model structure of the data collection and display control.The control can be used to collection and record parameters of pressure,temperature and position,and display these data in curves.So authors can see the variational trends of these parameters conveniently,and then improve the precision of pro-cess control.At the same time ,using the control can cut down the amount of labour greatly and shorten the development cycle of software design.更多还原
