基于NI的声压数据采集卡，利用labview程序采集15路麦克风信号并保存-The sound pressure based on NI data acquisition card, use 15 mic labview signal acquisition process and save

采用LabVIEW作为编程环境，通过计算机串口采集外部信号，并且对信号作相应的解算！-Use LabVIEW as a programming environment, acquisition external signal through the computer serial port, and the signal corresponding solver!
