摘　　要：为了测量物体移动或者旋转时的速度,以虚拟仪器技术为基础,分别以测量汽车门关闭时的速度和电机旋转时的转速为例,利用PCI-1711L数据采集卡采集传感器的脉冲信号,利用LabVIEW软件开发了测量速度的程序,测得汽车关门速度和电机转速;利用所开发的系统进行了实验验证,并进行了数据分析。该文给出了一条准确、方便、性价比高的速度测量途径。In order to measure the speed of moving or rotating object, based on the virtual instrument technology, the paper took the measurement of closing car door and rotating motor respectively for example, used the PCI - 1711L data collection card to acquire the pulse signal from sensor, developed the measurement software with LabVIEW to obtain the car door closing speed and motor rotating speed. The paper also used the developed system to carry out measurement, and gave the result of data analysis. The paper put forward an accurate, convenient and cost-effective way for speed measurement.
