| 摘 要： | 为实现对水下矢量声场信息的观测记录,以方便后续的矢量声场特性研究,以MSP430微功耗单片机为核心搭建信号采集存储系统平台.AD7655多通道高速模数转换器,经由MSP430单片机控制,完成对前端模拟信号的采样.经量化后的数据由MSP430单片机按固定时序,由IDE接口写入CF卡的大容量闪烁存储器中.为方便与PC机的兼容,CF存储卡中的数据是按照簇结构,以标准FAT32的DAT文件格式写入的.数据可方便地由PC机访问,该信号采集储存系统已实际应用于某水声设备中.

| Abstract: | For the purpose of recording the vector sound field information which can be used in the subsequent research of vector sound field feature, system platform for signals sampling and slorage is constructed with the micropower MSP430 microcontroller as a core. Controlled by MSP430 mierocontroller , analog signals are sampled by AD7655 high-speed multi-channel analogue to digital converter （ADC）. Quantified data is inputted into the large capacity CF flash memory via IDE ports according to fixed timing by MSP430 microcontroller. For the compatibility with PC, data in CF card are organized in standard FAT32 cluster DAT files. The data can be accessed by PC conveniently. This system has been used in the underwater acoustic equipment. |
