面向IMA综合处理系统的日志管理系统设计与实现

摘要

针对IMA综合处理系统的大规模软件运行需求,在分析其特点的基础上,提出了一种易于实现、使用方便的日志管理系统.系统主要分为三部分:基于Flash的日志管理、基于文件系统的日志管理和远程日志管理.在配有文件系统的模块上,提供了基于文件系统的日志管理,利用文件系统对数据管理的方式,管理日志记录的读写以及存储；在没有文件系统的模块上,提供基于Flash的日志管理,并根据Flash每次写一个扇区的特点,设计了异步写日志记录的机制,提高了Flash的写效率；同时设计了远程存取日志记录的机制,允许模块远程存取日志记录,扩大了日志记录的存储规模.系统是针对IMA综合处理系统的特点设计,能够满足航空电子系统对日志管理的需求.%In order to meet the requirements of the large- scale software running in the IMA integrated processing system, this paper firstly analysis the characteristics of this system, then puts forward a kind of log management system which is conveniently used and easily implemented. The system is mainly divided into three parts:log management based on Flash, log management based on file system and network log management. The module which has file system is provided with the log management based on file system. The way of data management in file system is used to manage the log reading and writing as well as storage. The other module which lacks in file system is provided with the log management based on Flash. According to the characteristics of Fash which is written a sector of data once, it designs the asynchronous writing mechanism of the log for improving the writing efficiency of Flash. While the paper designs the remotely accessing log mechanism which allows the module to remotely access log from other module,it extends log Storage size. The system is designed based on the characteristics of the IMA integrated processing system,so it can meet the needs of avionics system.
