1、摘 要本文根据任务书的要求设计了微位移运动的数字化测量系统。在分析模拟测量系统的设计思想和工作原理的基础上,对实验室所需的测量要求进行了合理的选择,包括种类、型号、技术参数等。为了对整个测量系统的运行进行控制,并对采集到的数据进行处理,编制了系统管理控制软件,本系统软件用Visual Basic 6.0编写控制界面,运行在Windows2000或Windows XP操作系统下,通过该软件能够显示微位移数据。本文在对PCL711B数据采集卡进行分析的基础上,将其应用于数字化电感测微仪的数字化改造。微位移经电感测微仪检测,变换成模拟电压量,传送到PCL711B数据采集卡,用数据采集卡把模拟量转化为
2、数字量,再用数字量在计算机上显示出来。测量软件用Visua Basic 6.0开发,通过对PCL711B数据采集卡进行一定的操作,实现包括自动定时采集数据、手动采集数据、数据存储等功能。本文阐述了系统方案设计、微位移机构测绘、PCL711B卡编程的流程分析、应用程序设计、运行效果分析等工作。指针式电感测微仪在机械零件的误差测量、物件的厚度测量、微位移的测量等方面有广泛的应用,利用微机的软硬件资源将指针式电感测微仪改造为数字化测量系统,以便对测试结果进行读数、存储、打印、以及进一步的数据分析处理,同时可制作美观廉价的虚拟仪器面板。在基于IPC的数据采集系统中采集卡是关键部件。关键词:微位移;PC
