摘　　要：本文结合某型直升机飞参数据记录的需求,提出了一种基于NandFlash的飞参数据管理方法,核心功能包括文件列表管理、坏块状态管理和数据读写管理。通过试验和验证表明该方法实现简单,CPU资源消耗少,可靠性高且无需考虑损耗均衡策略,适合在无文件系统支撑的嵌入式系统设计中使用。This paper presents a flight data management method based on Nandflash to meet requirements for the flight data recording of a certain helicopter.The core functions include file list management,bad block state management and data read and write management.Experiments and verification show that this method is simple to implement,consumes less CPU resources,has high reliability and does not need to consider wear-leveling strategies,and is suitable for use in embedded system design without file system support.
