  • Low-power wire rope safety diagnosis method and system
    Patent number: 11430314
    Abstract: A low-power wire rope safety diagnosis method and a system thereof are provided. Since a sensor should be continuously turned on to allow a plurality of sensor nodes to diagnose safety of a wire rope in real time and it consumes much power, there is provided a method and system which can perform the safety diagnosis only when a movement is detected while being in a standby mode to reduce the power consumption, and determine a defect more correctly and consistently by utilizing deep learning when defects are determined through a wire rope safety diagnosis.
