摘　　要：传统的矿井风速测量装置大多采用单点测量方式,文中设计了基于互相关原理的声学技术测速系统,包括信号源的选取、声源和声压传感器的布置、FPGA电路、FT2232H数据采集电路等;开发了一套基于LabVIEW的上位机软件系统,可以实现对风速的实时测量。实验结果表明,该测量系统可以实时准确测量风速。Traditional mine speed measuring devices mostly adopted single point measurement method,therefore,the acous⁃tical technology velocity measurement system based on cross⁃correlation principle was designed,including the selection of signal source,arrangement of sound source and sound pressure sensor,the core circuit of the FPGA,FT2232H data acquisition electric,and a software system of the host computer based on LabVIEW was developed.The experimental results show that the system can measure wind speed accurately in real time.
