System and method for detecting quality of food in refrigerator

Abstract

The invention discloses a system for detecting quality of a food in a refrigerator. The system comprises a monitoring module, a memory, a data processor, a data transmission module, a monitoring system controller, a display screen and a buzzer, wherein the monitoring module is connected with the memory and the data processor through the data transmission module; the monitoring system controller isconnected with the monitoring module and is used for controlling working states of the monitoring module; the data processor is connected with the display screen and the buzzer. Due to comprehensiveapplication of a gas sensor technique, a liquid-phase-gas-phase nano electrode detection technique and a nonlinear signal analysis technique, the quality of the food in the refrigerator can be precisely judged, the technical difficulty that the quality of the food in a conventional household refrigerator cannot be accurately detected can be solved, an intelligent household refrigerator capable ofmaking alarm for deteriorated foods can be achieved, and the food security protection capability of a common family can be comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a system and method for detecting the quality of food in a refrigerator. Background technique [0002] A refrigerator is an electronic device for food preservation that is indispensable in family life. It is composed of a compressor, a heat delivery device, a heat preservation chamber, and a temperature feedback unit. The traditional refrigerator only realizes the function of food storage and temporary transitional storage. The main defect is that it cannot provide intelligent reminders and alarms for the corrupted and qualitatively changed food and ingredients stored in it. Over time, it will cause pollution in the storage room of the refrigerator. If the food and ingredients are taken away, it will also pollute the food or ingredients of good quality, which not only brings economic losses to people, but more importantly, affects people's health and reduces the happiness i...
