摘要
设计了一种以DSP为核心的专用测量系统,该系统采用独特的测量方案,可以以较少数量的传感器完成重复性动态场强分布(相对值)的实时测量。文章介绍了系统硬件设计、测量方法的基本原理及其DSP实现,给出了软件流程及实验测量结果。结果表明该系统灵活可靠,且可节省大量传感器,能够以较低的成本完成瞬态声场的实时测量。
A special measure system which used DSP as the core is introduced. In this system by adopting some particular measure method, the real time field intensity of repetitive dynamic field can be obtained with a small number of sensors. The hardware constitution of system, the theory of measure method and the realization based on DSP are described. The software realization and measure results are presented. The system is flexible and reliable; moreover, it can realize measurement at low cost.
