摘要
论文设计了一个基于虚拟仪器技术的便携式水声监测仪,介绍了如何利用LabVIEW语言作为软件开发平台,USB-4431采集卡等作为硬件平台,对水声信号进行监测。论文对便携式水声监测仪的各模块进行了详细的论述,对其功能做了具体介绍。该系统能够实时对水声信号进行采集,对采集的信号进行实时存储、信号处理、信号分析,得出被测系统的信号特点及时延数据等信息。实验证明:该系统界面友好、功能强大、而且操作方便,在水声学实验中具有较高的应用价值。
This article designes a portable underwater acoustic monitor based on virtual instrumention technologies,and intro⁃duces how to use LabVIEW as a software development platform and uses NI USB-4431 acquisition card as a hardware development to develop derwater acoustic monitorr.The function of each module is discussed in detail.It realizes the multiple function of re⁃al-time signal acquisition lasted minutes,real-time storage,playback,signal analysis,etc.The delay data of the target signal is got⁃ten.The experiments show that the system has the advantages of simple design,convenient operation,which can realize high speed data acquisition and real-time graphical display,etc.
