Abstract: A cable life prediction method, includes: acquiring resistance value data indicating chronological change in a resistance value of a cable based on an operation of a managed device and an operating data, by a cable status management device, from a device user-side data management device, thereby, in the cable status management device, estimating wire-break progress in the cable based on at least one of the acquired resistance value data and the acquired operating data; and in the cable status management device, predicting a life of the cable based on a wire-break progress data and the operating data, and storing the predicted life of the cable as cable life prediction data. At least a device manufacturer terminal of a device manufacturer that manufactures the managed device or a cable manufacturer terminal of a cable manufacturer that manufactures the cable is configured to be accessible with the stored cable life prediction data.

Abstract: A disconnection detection method for detecting disconnection of a plurality of strands constituting a conductor of a cable wired in a device that is caused by motion of the device includes a data acquisition step of acquiring motion information data, which is data showing changes over time in information about motion of the device, and resistance value data, which is data of a resistance value of the conductor that changes in time series due to the motion of the device, an analysis step of analyzing the resistance value data based on the motion information data acquired in the data acquisition step and obtaining an index value to detect strand disconnection, and a disconnection detection step of detecting the strand disconnection based on the index value obtained in the analysis step.
