PROBLEM TO BE SOLVED: To provide a door opening/closing management system where fitting work is easy regardless of new design of a storage and post-fitting to an existing storage, capable of contributing to a reduction in manufacturing costs.SOLUTION: A door opening/closing management system includes: a detection section; a determination section; and an output section. The detection section is covered with a wall surface, is disposed in a storage provided with an opening/closing door to at least a part of the wall surface and detects variations of physical quantity in the storage in association with opening/closing of the opening/closing door. The determination section determines an opening/closing state of the opening/closing door on the basis of the variations of the physical quantity. The output section outputs determination results of the determination section to an outside.SELECTED DRAWING: Figure 2 |
