摘　　要：考虑次声波检测的广泛应用前景及目前国内相关研究的相对匮乏,设计了以STM32F103为控制核心的便携式次声检测仪。结合实时操作系统μC/OS-Ⅱ的多任务调度特性和ucgui图形用户界面简易绘图的特点,通过快速傅里叶变换(FFT)实现了对环境中次声波的检测与分析。软件部分均由C语言编程实现,易于系统移植和功能扩展。该系统具有成本低、操作简单、准确度和稳定性高等优点。Considering the broad application prospects and lack of relevant research of infrasound detection,a portable infrasound detector was designed using STM32F103 as the control center.Combined with the multi-task scheduling feature of μC/OS-Ⅱ OS and graphical user interface support of ucgui,it presented the realization of the detection and analysis of infrasound by FFT algorithm.The software was accomplished by C programming,and it was easy to transplant and expand.The whole system performs the characteristic of low cost,easy operation,high accuracy and stability.
