摘要
机载设备非易失存储器中存储的故障信息是故障排查的重要依据。当前机载设备往往采用事件触发的记录方式,该方式存在消耗时间动态范围宽、可拓展性不强,适用范围窄的缺点。本文设计实现一种故障记录机制,克服现有记录机制的不足。首先,明确了常用非易失存储器的特点;其次,设计了故障信息内容格式;然后,设计了故障记录机制;最后以EEPROM为例,实现了该记录机制。
The fault information stored in the nonvolatile memory of airborne equipment is an important basis for fault troubleshooting.At present,airborne equipment often adopts event triggered recording mode,which has the wide time-consuming range,weak scalability and narrow application range.This paper designs and implements a fault recording mechanism to overcome the shortcomings of the existing ones.Firstly,the characteristics of common nonvolatile memory are clarified;secondly,the content format of fault information is designed;then,the fault recording mechanism is designed;Finally,taking EEPROM as an example,the recording mechanism is realized.
