Digital smart real showcase warning system, method, and program

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.

1 . A digital smart real showcase warning system comprising:
 a temperature inputting means configured to input a temperature inside the chamber of a showcase, a refrigerator, or a freezer (hereinafter, referred to as a “showcase or the like”) over time;   a storing means configure to store calendar information n which changes in the temperature are accumulated;   a failure determining means configured to determine the showcase or the like to be failing when a difference between the calendar information read out from the storing means and the temperature is greater than a predetermined value;   a calculating means that calculates an expected date and time of an increase in temperature of a product in chamber of the showcase or the like to a warning temperature being a predetermined temperature so high as to be unsuitable for refrigerating or freezing when the failure determining means determines a failure; and   a notifying means that notifies warning information including the expected date and time calculated by the calculating means.   
     
     
         2 . The digital smart real showcase warning system according to  claim 1 , further comprising:
 an outdoor air temperature inputting means that inputs outdoor air temperature information;   an outdoor air temperature predicting means that predicts a future predicted outdoor air temperature from outdoor air temperature information inputted by the outdoor air temperature inputting means; and   a control means that controls a showcase temperature based on the predicted outdoor air temperature predicted by the outdoor air temperature predicting means.   
     
     
         3 . The digital smart real showcase warning system according to  claim 1 , wherein when the temperature deviates from a normal temperature change pattern, the failure determining means determines that the showcase or the like is failing. 
     
     
         4 . The digital smart real showcase warning system according to  claim 1 , wherein when an increase in the temperature is a change in temperature caused by defrosting in the showcase or the like, the failure determining means does not determine the temperature increase as a failure. 
     
     
         5 . (canceled) 
     
     
         6 . The digital smart real showcase warning system according to  claim 1 , wherein the notifying means transmits the warning information to a terminal device that a person who maintains the showcase or the like can keep with him/her. 
     
     
         7 . A digital smart real showcase warning method comprising:
 a temperature inputting step of inputting a temperature inside the chamber of a showcase or the like over time;   a storing step of storing calendar information in which changes in the temperature are accumulated;   a failure determining step of determining that the showcase or the like is failing when a difference between the calendar information ready out by the storing step and the temperature is greater than a predetermined value;   a calculating step of calculating an expected date and time of an increase in temperature of a product in chamber of the showcase or the like to a warning temperature being a predetermined temperature so high as to be unsuitable for refrigerating or freezing when the failure determining step determines a failure; and   a notifying step of notifying warning information including the expected date and time calculated by the calculating step.   
     
     
         8 . (canceled) 
     
     
         9 . A tangible non-transitory computer-readable storage medium, the computer-readable storage medium is configured to store a program executable by a digital smart real showcase warning system, the digital smart real showcase warning system upon execution of the program is configured to perform the digital smart real showcase warning method of  claim 7 .
