FAILURE SIGN DETECTION SYSTEM AND FAILURE SIGN DETECTION METHOD

A failure sign detection system 100 includes: a data storage unit 160 that retains data at the time of normal operation of each action, as learning data, with respect to a manufacturing operation of a manufacturing apparatus 2 composed of a plurality of actions; a sensor (acceleration sensor 6) that measures the manufacturing operation of the manufacturing apparatus 2; an action detection unit 110 that detects an action start of each action in the manufacturing operation; a divided data collection unit 180 that divides measured data, which is measured by the acceleration sensor 6, into divided data for each action and collects the divided data; and a data analysis unit 140 that analyzes an abnormality of each action on the basis of a comparison between the divided data and the learning data of each action.
