摘　　要：在瞬态运动参数测试中,对存储测试系统的实时性和功耗提出了更高的要求。提出了一种基于STM32的嵌入式存储测试系统的设计方案,介绍了该系统关键部分的软硬件设计,主要包括模拟信号调理、数据采集存储和USB数据回读。该系统具有实时性好、体积小、功耗低的特点,适合于恶劣环境下加速度信号的采集存储。试验结果表明,该系统工作稳定,实现了设计目标。In the test of transient motion parameters, the real-time and power consumption requirements of the storage measurement system are very high. An embedded storage measurement system based on STM32 is designed. The hardware and software of the key parts of the system are introduced,including analog signal modulation,data acquisition and storage, USB data read back. With strong real-time, small size and low power consumption, the system is suitable for working in harsh environments. The experiment results show that the system works stably and achieves the design goal.
