Fecha de publicación: 30/12/2022 Fuente: Wipo "IOT" A server for providing a method and a device for providing an industrial Internet of things (IIOT)-based remote control service for a smart factory can obtain programmable logic controller (PLC) data and log data of Internet of things (IoT) devices from the IoT devices. The server can obtain physical sensing data from IoT sensors. The server can obtain operation images of the IoT devices from closed-circuit television (CCTV) terminals. The server can learn error situations that occur in the IoT devices based on the PLC data and the log data through machine learning. The server can determine that a first error situation occurs in a first IoT device among the IoT devices based on the PLC data and the log data. The server can control the first IoT device according to a first preset scenario according to the occurrence of the first error situation The server can provide a user terminal with information on the first error situation and a first image of the first IoT device recorded by the CCTV terminals during the time when the first error situation has occurred in the first IoT device. Therefore, users can obtain state information and CCTV image information of each device in real time. COPYRIGHT KIPO 2023
