Alarm information analysis method and device

The invention discloses an alarm information analysis method and a device, and the method comprises the steps: searching an alarm paraphrase mapped by alarm information in an alarm information libraryafter the alarm information is received; if the alarm paraphrase mapped by the alarm information is not found in the alarm information base, analyzing the alarm paraphrase of the alarm information based on a cache database; and storing the alarm information and the parsed mapping relationship of the alarm paraphrases into the alarm information base. According to the alarm information analysis method, in alarm information analysis, the fields do not need to be analyzed one by one according to the cache data; the alarm paraphrase mapped by the alarm information can be directly inquired from thealarm information base, and the data volume used for analyzing the alarm information in the alarm information base is much less than that in a cache database, so that the alarm information can be analyzed more efficiently, th
