设计了一种基于光纤声传感器进行远场声源目标声音信号采集的硬件平台方案。该平台采用NI公司生产的USB-6210数据采集卡实现光纤麦克风阵列的数据采集,通过数据采集卡将声音信号采集后输入计算机,利用计算机算法可以实现远场声源目标的识别和定位。该平台解决了其他麦克风收音效果较差,噪声较大的缺点,实现了较高质量的声音信号采集。实验数据表明,设计的平台是有效和可行的,可以满足声源定位系统的要求。
A hardware platform scheme based on optical fiber acoustic sensor for acquiring target sound signal of far-field sound source was designed. The platform uses the NI-produced USB-6210 data acquisition card to realize the data acquisition of the optical fiber microphone array. The data is collected by the data acquisition card and then input into the computer. The computer algorithm can realize the identification and location of the far-field sound source target. The platform solves the shortcomings of other microphones receiving less effective sound and larger noise, and achieves higher quality sound signal acquisition. Experimental data show that the design of the platform is effective and feasible to meet the requirements of the sound source positioning system.
