摘要
本文介绍用 IBM-PC 机与 A/D 板组成的数据采集及处理系统。只要在 IBM-PC 微型机的扩展槽内插入 A/D 数据采集板,再配以相应软件程序,可对模拟信号进行数据采集、存贮、处理和显示。本文最后介绍了该系统在汽车钢板弹簧振动测试中的应用。
This paper describes the test data acquisition and processing system which consists of IBM-PC microcomputer and A/D conversion board.In order to com- plete the data acquisition,storing,processing and displaying of analogy signal,the inserting of a A/D conversion board in the extended slot of IBM-PC microcomputer and the corre- sponding program are just needed.Finally this paper introduces the application of this sys- tem in the spring vibration test of autobody sheet.
