摘　　要：通过对现有软件黑匣子性能的分析,指出其在软件故障诊断中所存在的缺陷。提出了直接使用带有后备电源的内存或非易失性随机存储器来作为记录软件运行信息载体的方法,有效避免了软件失效前关键信息的丢失问题。增加了进出模块时间的记录,以及在必要的时候记录某些反映模块健状程度的关键数据。解决了软件故障诊断时无法还原现场的难题,为软件质量的提高开辟新的途径。Through the analysis of the performance of having existed software black box,the defects are pointed out in software fault diagnosis.A method of directly using memory with a backup power supply or non-volatile random access memory as the carrier to record software running information is proposed,which can effectively avoid the loss of critical information before software failure.The record of the time to pass in and out of module is added.Where necessary,it can also record some crucial data which is in response to the robust of modules.This method efficiently solves the problem of the disability to restore the fault site on software fault diagnosis,and provides a new method for improving software quality.
