摘　　要：对一个典型的综合化航空电子系统中的存储单元进行分析,解决其配置的事务型文件系统在实际使用一段时间之后,因自身结构不断增加导致查找有效信息的时间持续增长,影响实际的文件操作效率的问题。设计了一种机载存储系统快速维护方法,通过增加预设的逻辑分区作为临时存储区,设计适合工程使用的操作流程,实现在不影响原有存储文件的情况下,对文件系统进行格式化操作,且能够保证操作的各个时间点系统发生意外掉电等异常情况后能够有效恢复,并对系统进行了功能和可靠性性测试,结果表明满足设计要求,实现了整个维护过程的安全可靠。Analyze the storage unit in a typical integrated modular avionics system,in order to solve the problem that the configured transaction file system has been used for a period of time,due to the continuous increase of its own structure,which leads to the continuous increase of the time to find effective information,which affects the actual situation.Designed a fast maintenance method for airborne storage system.By adding a preset logical partition as a temporary storage area,design an operation process suitable for engineering use.Achieve formatting operations on the file system without affecting the original stored files.It can ensure that the system can effectively recover after unexpected power failures and other abnormal conditions occur at various points of operation.The system has been tested for function and reliability,and the results show that the design requirements are met,and the entire maintenance process can be safe and reliable.
