摘　　要：为了解决水下轨迹测量系统中数据更新速率快、数据量大不便于实时处理的问题,本文开发了一种对声学传感器以及惯性测量单元信号进行实时采集存储的系统,该系统以FPGA为主控单元,设计了AD转换与NANDFLASH控制器以实现对原始数据的采集和存储功能,并可通过USB与上位机进行数据读取和指令下发,经过实际测试,结果表明本系统能稳定采集和储存原始声信号和IMU数据,通过上位机读取后便于后续数据分析和轨迹解算。For In order to solve the problems of fast data update rate and large amount of data in underwater trajectory measurement system, this paper develops a real-time acquisition and storage system for acoustic sensor and inertial measurement unit signals. The system takes FPGA as the main control unit,develops AD converter and NANDFLASH controller to realize the acquisition and storage of raw data, and can read and issue instructions through USB and the upper computer. After the actual test, the results show that this system can stably acquire and store the original acoustic signal and IMU data, which is convenient for subsequent data analysis after being read by the upper computer.
