Title:
GNN-BASED MASTER STATE GENERATION METHOD FOR REAL-TIME ANOMALY DETECTION
Document Type and Number:
WIPO Patent Application WO/2022/225117
Kind Code:
A1
Abstract:
The present specification discloses a method of analyzing log data output from a programmable logic controller (PLC) to generate a master state corresponding to a normal state in a repeating cycle. In addition, as data preprocessing for master state generation, a method of generating log data as graph data is disclosed. A master pattern generation method and a cycle analysis model training method according to the present specification are distinguished from the conventional art in that the methods correspond to a technology of processing machine control language (low-level language), which is difficult to be analyzed by humans, and converting same into analyzable language (high-level language), that is, a machine language processing (MLP)-based technology which can be understood by humans and analyzed by an executed machine language (language for controlling a machine) computer.
