SYSTEM FOR MONITORING PRODUCT QUALITY IN REAL TIME

摘要

Disclosed is a system for monitoring product quality in real time by using an RFID tag and a QR code. The product quality monitoring system includes: an RFID tag which is attached to a first packing container in which a product is packed, and transmits atmospheric history information comprising at least one of temperature, humidity, and gas concentration, which has been measured, and an identifier for a product distribution history; a QR code which is attached to a second packing container, in which the product is packed and is relatively smaller than the first packing container, or the product itself, and stores the identifier and address information of a product quality predicting server; a product distribution history DB which stores the atmospheric history information and the identifier which are received from the RFID tag; a user terminal which connects with the product quality predicting server corresponding to the address information stored in the captured QR code, and requests a quality index of the product; and the product quality predicting server which calculates the quality index of the product or a time when the product has a specific quality index, from the atmospheric history information received from the product distribution history DB in response to the request of the user terminal.
