摘要
为解决车载CAN总线记录仪长时间记录时数据量与存储容量之间的矛盾,设计出基于"FPGA+单片机"的大容量存储系统;详细阐述了系统的整体结构、硬件电路设计,采用两种存储模式,将数据导入SD卡中后,计算机可以直接读取SD卡中的数据。实验表明,该系统可以稳定工作。
In order to solve the contradiction between the amount of data and storage capacity of vehicle information recorder based on CAN bus, a mass storage system is designed based on FPGA-plus-MCU. The whole structure and hardware electric circuit are introduced. Two kinds of storage modes are used, and the computer can read data directly from SD card after data input to SD card. Experiments show that this system works stably.
