Patent number: 12346084Abstract: The present disclosure discloses a master pattern generation method which is a major pattern in a repeated cycle by analyzing programmable logic controller (PLC) logic, and a method for training a model that may analyze an error of a cycle using the generated master pattern. The master pattern generation method and the training method for a cycle analysis model according to the present disclosure are different from the related art in that the methods are a technology of processing a machine control language (low-level language) that is difficult for humans to analyze and converting the machine control language into an analyzable language (high-level language), i.e., a machine language processing (MLP)-based technology that analyzes the executed machine language (a language that controls a machine) with a computer and can be understood by humans.Type: GrantFiled: April 8, 2022Date of Patent: July 1, 2025Assignee: UDMTEKInventors: Gi Nam Wang, Jun Pyo Park, Yeon Dong Kim, Nam Ki Kim, Hee Chan Yang, Yoon Woo Ha, Seung Jong Jin

Publication number: 20230027840Abstract: Disclosed is a method of analyzing a programmable logic controller (PLC) logic to detect whether an anomaly that deviates from a standard pattern occurs in a repeated cycle. After modeling and patterning an operation pattern of automation equipment and processes with a graph, an anomaly detecting model capable of detecting whether a pattern is abnormal may be constructed as a graph AutoEncoder model. By detecting the change in the process pattern, it is possible to early detect the anomaly of the equipment and processes.Type: ApplicationFiled: July 20, 2022Publication date: January 26, 2023Applicant: UDMTEK CO., LTD.Inventors: Gi Nam Wang, Jun Pyo Park, Seung Woo Han, Geun Ho Yu, Min Young Jung, Hee Chan Yang, Seung Jong Jin
