TEMPERATURE EVALUATION SYSTEM, AND ARTICLE MANAGEMENT SYSTEM IN WHICH SAME IS USED

Document Type and Number:

WIPO Patent Application WO/2018/225319

Kind Code:

A1

Abstract:

In order for the present invention to provide a temperature evaluation system and an article management system with which it is possible to evaluate the highest temperature reached or the lowest temperature reached from the color optical density of a thermosensitive material, the temperature evaluation system according to the present invention evaluates the temperature of an indicator in which a thermosensitive material is used, wherein the temperature evaluation system is characterized by being provided with: a read-in device that acquires image data pertaining to the indicator; a storage device that stores the relationship between color density and temperature for each thermosensitive material; and a processing device provided with a color density estimation unit that estimates the color density of the thermosensitive material from the image data, a material identification unit that specifies the thermosensitive material used in the indicator, and a temperature estimation unit that selects, from among the relationships between color density and temperature for each thermosensitive material, the relationship between color density and temperature of the thermosensitive material specified by the material identification unit, and that estimates the highest temperature reached or the lowest temperature reached from the relationship between color density and temperature of the specified thermosensitive material and the color density estimated by the color density estimation unit.
