Refrigerator food freshness segmentation reminding system and application thereof

Abstract

The invention discloses a refrigerator food freshness segmentation reminding system and an application thereof. The refrigerator food freshness segmentation reminding system is characterized by comprising a sensor module, a control module, a display module, an alarm module and a press key module, wherein the sensor module is used to obtain total volatile base nitrogen content values of food in a refrigerating chamber of a refrigerator and / or a freezing chamber of the refrigerator, and send the total volatile base nitrogen content values to the control module, the press key module respectively sets different levels of total volatile base nitrogen criticality values according to the different total volatile base nitrogen content values of the food, and the control module receives the total volatile base nitrogen content values, compares the total volatile base nitrogen content values with the different levels of the total volatile base nitrogen criticality values, judges signals of the levels where the total volatile base nitrogen content values are located, and sends the signals to the display module to perform character or icon caution and to the alarm module to perform voice caution and / or lamplight alarm caution and / or short message caution for the refrigerator. The refrigerator food freshness segmentation reminding system can effectively monitor fresh status of all kinds of the food in the refrigerator in real time, and guarantees edible safety of the food.
