Learning device, diagnostic system, and model generation method to diagnose abnormality based on temperature measurement in a production facility

Abstract

A learning device and other techniques allow accurate diagnosis of a production facility. A learning device () includes a data acquirer that acquires data for learning, and a model generator that generates a learning model for inferring a condition of a workpiece () handled in a production facility () on the basis of the data for learning. The data for learning includes setting data indicating a setting of the production facility (), image data indicating an image of the production facility () captured by a camera (), temperature data indicating a surface temperature of the production facility () measured by a temperature sensor (), distance data indicating a distance from a range sensor () to the production facility () measured by the range sensor (), and condition data indicating the condition of the workpiece () handled in the production facility ().
