摘要:随着时代的迅猛进步,科学技术的飞速发展以及电子技术的不断更新,人们在生活工作科研等方面对于方便快捷直观的要求也是越来越高。于是开始了通过对拉力采集数据可视化的研究。
人们同样也想通过这样的方式对于拉力所采集的数据清晰、精准性能够提高,并且可以更直观的分析以及作图。本文主要介绍使用VB来编写拉力采集上位机的软件,因为在所有的编程语言中,用VB来编写上位机软件无疑是最简便也是最容易上手的。在此篇文章中主要介绍了拉力测试仪、VB的简介及发展历程。当然软件设计的思路是本文的重中之重,后面的内容有设计的框图、部分源程序以及程序运行后的界面图。这个程序主要是用来对拉力进行数字化的监控,从而在工业、科学中更直观的对拉力进行测试。23329

Programming A Software Of Pull Gathering For Upper Computer In The VB Language
Abstract:With the rapid progress of the times, the rapid development of science and technology and electronic technology, constantly updated, people living and working in research and other aspects of the requirements for convenient and intuitive is also increasing. So began the study through data visualization to pull collection. Think this way pull the data collected clarity, precision can be improved, and more intuitive analysis and mapping. This paper describes the collection to write Rally PC software using VB, because in all programming languages, using VB to write PC software is undoubtedly the easiest and most easy to use. In this article introduces the tensile tester, VB introduction and development process. Of course, the software design is the most important ideas in this article, there is a block diagram of the content behind the design, as well as part of the program to run after the source interface diagram. This procedure is used to digitize the tension monitored to industrial, scientific and more intuitive for the tensile test.
