System for monitoring product quality in real time

Abstract

The present invention relates to a system for monitoring product quality in real time, and in particular to a system for monitoring product quality using an RFID tag and a QR code. To this end, the system for monitoring product quality according to the present invention includes: an RFID tag, attached to a first packaging container in which a product is packaged, for transmitting an identifier and waiting history information including a measured temperature and humidity; a QR code attached to the product or to a second packaging container in which the product is packaged, for storing the identifier and address (link) information of a product quality prediction server; a product circulation history database for storing the identifier and the waiting history information received from the RFID tag; a user terminal for imaging the QR code, accessing the product quality prediction server corresponding to the imaged QR code, and requesting a quality index of the product; and said product quality prediction server for calculating, from the waiting history information received from the product circulation history database according to a request from the user terminal, the quality index of the product and a point in time at which the product has a predetermined quality index.

Description

technical field [0001] The present disclosure relates to a system for monitoring product quality in real time. More specifically, embodiments of the present disclosure relate to a system for product quality monitoring using RFID tags and QR codes. Background technique [0002] In recent years, more and more research has been conducted on the application of radio frequency identification (RFID), which refers to an advanced technology in which a target object is analyzed over a long range by using a predetermined frequency band, To read tens to hundreds of information. Radio Frequency Identification requires a tag in the form of a sticker that includes a microprocessor chip and is attached to the product and a reader or antenna that is capable of identifying the tag information. [0003] Since the product information is captured by RFID, there is no need for the cashier to scan the image of the barcode attached to the product. Every time shoppers check out, they can save sh...

Problems solved by technology

While existing barcodes and magnetic cards suffer from a gradual degradation in recognition rate over time, in the case of RFID, this is a redundant problem

[0005] In general, although refrigerators are used to prevent and delay food spoilage, however, due to the variety and quantity of food stored and kept in refrigerators, if not closely watched, food can be stored in the form of unorganized piles in the refrigerator. storage space, so without searching the storage space of the refrigerator, it is difficult to identify the type of food, and the food is often expired, rotten, and thrown away
