Abstract
A digital smart real showcase warning system (100) comprises a showcase (110), a freezing machine (20), a showcase control unit (18), and a portable device (70), wherein a control unit (81) of the showcase control unit (18) inputs a temperature of the showcase (110) over time, and determines that a freezing function for the showcase (110) is failing based on the inputted temperature, the control unit (81) calculates an expected date and time of an increase to a warning temperature (an increase in temperature of a product in the showcase (110) to a predetermined temperature so high as to be unsuitable for refrigerating and freezing), and the control unit (81) causes a notifying means (87) to warning-display the expected date and time and to transmit warning information to the portable device (70), whereby the occurrence of a product loss can be prevented.
