| 中文摘要: |
| 设计了一个基于AT89S52单片机的适用于低频(20Hz～2000Hz)、小区域的高精度实时三维声源定位系统。该系统包括三个模块:声源采集和模数转换模块;时间延迟采集模块;串口通信和定位算法模块。在1000m3范围内,根据该系统可以实时快速地定位出三维空间声源的位置,且定位最大水平偏向角误差为±0.3°,最大俯仰角误差为±0.5°。 |
| 英文摘要: |
| A real-time high-accuracy three-dimensional localization of sound source system is designed ba-sed on AT89S52 single-chip microcomputer. It is applicable to detecting the aural signal of low frequency ranging from 20Hz to 2000Hz. It is mainly composed of three modules: sound source gathering and analog-to-digital conversion module,time delay gathering module and serial communication and algorithm module. In the region of 1000m3,the three-dimensional position of sound source can be localized rapidly in real-time. The maximum positional errors are ±0.3 degree in horizontal direction and ±0.5 degree in vertical direction. |
