基于LabVIEW的短基线测量系统设计

针对传统短基线测量系统硬件设计复杂且不易扩展的问题,设计了基于计算机和虚拟仪器的短基线测量系统.使用数据采集卡NI USB-6366采集短基线阵元收到的水声信号,在LabVIEW开发环境下,采用生产者/消费者架构和队列消息处理器的复合设计模式,结合多线程、队列同步等技术实现了数据采集、参数估计、定位解算、存储上传和动态显示等功能.系统运行高效可靠,测量精度高,其设计模式为采集测量应用提供良好的借鉴作用.

Short Baseline Measurement System Based on LabVIEW

In order to solve the problems of complex hardware design and insufficient flexibility, a short baseline meas- urement system based on computer and virtual instrument is designed. The NI USB-6366 data acquisition card is used to col- lecl the acoustic signals received by the short baseline array. In the LabVIEW development environment, producer/consumer structure and queue messages processor complex design pattern are combined with multithread technology, and the queue synchronization technology to realize the functions of data acquisition, signal parameter estimation, positioning calculation, data storage, uploading and dynamic display. This system is proved to be efficient, reliable, and has high measurement accu racy. whose design patterns provide a good reference for application of collection and measurement system.
