PCL711B采集卡在测微仪数字化中的应用
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、打英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。

Abstract
According to the requirements, this paper designs the digital measurement system of micro-displacement movement. After analysis the design andwork principle of analog measurement system, reasonable choice has done on the requirements of lab measure, including types, model, technical parameters, etc. To control the operation of the measurement system, and to control the collected data processing, management software is made. The system uses Visual Basic 6.0 to make the control interface, running in Windows2000 or Windows XP operating system, and achieve the function of the displaying micro-displacement data.
This paper base on carrying out the analysis of the PCL711B data collecting card,it make it have application in Digilalization transformation of Digital inductive micrometer. Micrometric displacement is detected by inductance micrometer,transfered to simulationvoltage quantity,and then transmit it to the PCL711B Data collecting Card,show it on the PC. Measurement software is developed in Visua Basic 6.0,according to the operations of PCL711B Data collecting Card,to achieve the functions of automatic and timing collecting data,manual drive collecting data,data memory etc. This paper makes a presentation on system desin,micro displacement mapping,Flow analysis of PCL711B Card’s programming,applications design,operational effect analysis etc.
Pointer type inductive micrometer have extensive application in the error of measurement of mechanical parts, thickness measurement of objects,measurments of micro movement.etc,in the use of computer hardware and software resources, reconstruction Pointer type inductive micrometer to Digital measuring system,it makes the test result in the read, store,print,and further analysis of data more convenient,at the same time,we can make it Beautiful cheapvirtual instrument panel.Base on the IPC data collecting, data collecting card is the key parts.
