Fault diagnosis and early warning system and method based on configurable knowledge base

The invention relates to a fault diagnosis and early warning system and method based on a configurable knowledge base, and the system comprises an event server which generates an event for diagnosis and early warning according to the triggering condition of configuration; the data preprocessing module is used for generating data for diagnosis and early warning according to a configured preprocessing rule; the diagnosis and early warning knowledge base is a configurable early warning knowledge base based on fuzzy mathematics and a fault diagnosis principle and comprises early warning and corresponding criterion information; and the rule inference engine is respectively connected with the event server, the data preprocessing module and the diagnosis and early warning knowledge base, and is used for processing the generated data by adopting the data preprocessing module and the generated event triggered by the event server, and carrying out calculation according to the information in the diagnosis and early warn
