  • Patent number: 8907243
    Abstract: The tension measuring unit that measures a physical amount corresponding to tension of a wire in a wire transport system, the fluctuation recording unit that records the physical amount measured by the tension measuring unit, the fluctuation analysis unit that obtains an average value, variation, and frequency analysis data of the recorded physical amount as an analysis result of the physical amount, the maintenance necessity determining unit that compares the analysis result with a reference value and determines whether maintenance is needed based on a comparison result and the display unit that displays a determination result are included, and it is made possible to accurately determine the time for maintenance for various components used in the wire transport system without using a measuring instrument.
