摘要
介绍了以LabVIEW8.5软件为平台开发的声速测量虚拟仪器系统的组成,以及应用系统测量声速的原理和方法,通过对空气和水这2种介质在不同温度下的声速测量,对仿真实验的结果进行了分析,得出了在不同温度下这2种介质的声速,验证了系统的可靠性和准确性,程序设计仿真效果符合实际实验。该研究在工农业生产上有一定实用价值。
This paper introduces the composition of virtual instrument for sonic speed measurement developed based on LabVIEW 8. 5, the principle, and methods of measuring sonic speed using this virtual instrument. It measures the sonic speed in air and water in different temperatures. We analyze the results from the simulated experiment and gets the sonic speed in these two medium in different temperatures. The results prove the reliability and accuracy of the virtual instrument. The programmed simulated experiment is similar to the actual experiment. The research which is meaningful in industrial and agricultural production and application.
