摘　　要：为满足当前数据记录系统对国产化率和可靠性提出的更高要求,文中设计并实现了一种针对基于国产eMMC芯片数据记录系统的高可靠嵌入式软件方案。软件采用模块化设计思路,在各个模块的设计中加入防错及报警措施以提高系统的可靠性,并充分利用FreeRTOS的多任务并行处理技术、LwIP和FATFS文件系统来提高开发效率和系统的兼容性。经过实验验证可知,基于该软件方案的数据记录系统能满足大于100 GB的数据存储容量、超过20 MBps的数据读取速度和99.98%的错误检测率。In order to meet the higher requirements of the on the capacity and reliability of data recording system,this paper designs and implements an high reliable embedded software for a data recording system based on domestic eMMC chips.The software uses modular design idea and FreeRTOS multi-task parallel processing technology to achieve efficient multi-task operation.In the design of each module,error prevention and alarm measures are added,which greatly improves the reliability of the system.And make full use of LwIP and FATFS file system to improve development efficiency and system compatibility.Through experiments,the system based on the embedded software can meet the data storage capacity of more than 100 GB and more than 20 MBps data reading speed and 99.98%error detection rate.
