Abstract: Aiming to the problem of obtaining fault scene information from the actual fault diagnosis, this paper proposes a method to obtain fault scene information through software runtime fault injection, designs and implements a runtime software fault injector, and gives the grammar of fault script, fault library and the algorithm of the injector. Experimental results show that the injector can inject fault into software and obtain fault scene information effectively.

Key words: fault diagnosis, fault injection, software fault injector

摘要： 针对实际故障诊断中难以有效获得故障现场信息的问题，提出通过在软件运行时注入故障的方式获取故障现场信息，设计并实现一种运行时软件故障注入器，给出其中的故障脚本描述语言、故障库和故障注入器算法。实验结果表明，该注入器能有效实现故障注入，获取故障现场信息。
