  • Patent number: 11270473
    Abstract: In an operation management system in the related art, it is necessary to add an identification mark such as an RFID tag to each component to be managed and prepare a fastening tool having an antenna. In contrast, a mechanical fastening unit management method is provided using an augmented reality space generated by superimposing a virtual space on a real space. In the augmented reality space where a real fastening unit (RBn) and a virtual fastening unit (IBn) are in a one-to-one correspondence, information that the real fastening unit is selected as a fastening target is acquired with a camera or the like, and analyzed by an augmented reality server connected to the camera. Accordingly, it is possible to easily record that a predetermined operation is progressing as scheduled, and to provide a high quality mechanical fastening unit management method or system that is low in operation cost.
