Abstract

The invention relates to a subway signal system log intelligent analysis method, device and equipment and a medium. The method is realized by constructing a multi-stage security architecture of an internal security network-network isolation region DMZ-public network, firstly, log data preprocessing and encryption are carried out in the network isolation region DMZ, secondly, reverse communication is blocked through unidirectional transmission hardware, and then, accurate analysis is carried out by utilizing a large model association version demand and log keywords, so that the log data encryption is realized. And finally, establishing a global knowledge base to mine common hidden dangers. Compared with the prior art, the method has the advantages that on the premise that absolute safety of the core production network is ensured, log data aggregation of the whole road network is achieved, and intelligent real-time analysis and early warning are carried out.
