  • Patent number: 12346084
    Abstract: 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.

  • Publication number: 20250094773
    Abstract: A method, of training an anomaly detecting model using a plurality of pieces of graph data, includes: (a) inputting one piece of graph data that has not yet been input, among the plurality of pieces of graph data, to a graph neural network (GNN) AutoEncoder calculating a probability of each edge as input data; (b) calculating a difference value (hereinafter, “edge difference value”) between an edge probability value of reconstructed data output by the GNN AutoEncoder and an edge value of the input data; (c) calculating an average value (hereinafter, “positive edge loss”) of a positive edge and an average value (hereinafter, “negative edge loss”) of a negative edge using the edge difference value, and calculating an edge prediction loss value of the reconstructed data by summing the positive edge loss and the negative edge loss; (d) retraining the GNN AutoEncoder until the edge prediction loss value is minimized.

  • Publication number: 20230027840
    Abstract: 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.

  • Patent number: 8813897
    Abstract: An impact absorbing apparatus of a vehicle includes a back beam to secure an impact absorbing space while retreating rearward at the time of a collision accident with a pedestrian. This makes it possible to prevent direct contact between the back beam, which is a rigid body, and the pedestrian. Therefore, injury to the pedestrian may be significantly decreased.

  • Patent number: 8764079
    Abstract: A pedestrian protective radiator grill includes a radiator grill, an operation unit, and a guide unit. The radiator grill is provided at a front end portion of a vehicle and has an upper end portion that moves forward away from a vehicle body so that the radiator grill becomes perpendicular to the ground. The operation unit is connected to the radiator grill and pushes the radiator grill in a forward direction of the vehicle when an impact signal is input. The guide unit provided under the radiator grill guides forward linear movement of the radiator grill when the radiator grill is pushed forward by the operation unit, and guides rotational movement of the upper end portion of the radiator grill after the radiator grill reaches an end of its movable range.
