本文介绍一个利用计算机采集传感器输出信号的数据采集系统。该系统将一个光栅式 位移传感器与计算机联系起来，通过设计一个计算机接口卡和接口卡程序，用计算机来控制传感器动作及信号采集。 关键词：光栅式位移传感器 计算机接口卡数据采集 Abstract: This paper describes a data-picking system that uses a computer to pick up signals output by the transducer. In this system, a computer interface card and its corresponding interface card program are designed in order to control a grating displacement transducer's action and pick up signals. Key words: grating displacement transducer Computer interface card data-picking
