摘　　要：用于测量和计算的低成本的嵌入式设备节点往往需要长时间、实时地记录数据,而设备自身存储空间已经不足以存储节点所有有用的数据,在综合考虑成本和效率的情况下,利用英飞凌高性能ARM Cortex-M4架构的XMC4500单片机,设计出可以把CAN总线数据存储至本地SDHC卡的系统。详述了系统组成硬件原理和软件流程,并进行了关于系统实时性存储压力、通用性和稳定性的实验,结果表明,设计的系统具有较好的通用性,高稳定性和很好的实时性,可以提高数据处理分析的效率,极大地减少人力的使用和时间的浪费。The low-cost embedded device nodes for measuring and calculating often need to record data in a long time, and the storage space of the device is inadequate to store all useful data. With regard to both cost and efficiency, a system is designed using Infineon XMC4500 microcontroller of high performance ARM Cortex-M4 architecture,to store the CAN bus data to the local SDHC card. This paper describes the hard- ware principle and software flow of the system, and conducts experiments on real time storage pressure, gen- eral purpose and stability of the system. The experimental results show that, the designed system has good generality, high stability and good real-time performance, thus improving the efficiency of data processing and greatly reducing the consumption of time and labor.
