Abstract

A 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 and an identifier for a product distribution history; a QR code which is attached to a second packing container 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.

Claims

1. A product quality monitoring system, comprising:

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 information, which has been measured, and an identifier for a product distribution history;

a QR code which is attached to a second packing container, which the product is packed in 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 that stores the atmospheric history information and the identifier which are received from the RFID tag;

a user terminal that 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 that 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.

2. The product quality monitoring system as claimed in claim 1, wherein the product quality predicting server calculates the quality index of the product from the atmospheric history information which is received from the RFID tag, by using a quality predicting algorithm for predicting the quality of the product by means of the atmospheric history information.

3. The product quality monitoring system as claimed in claim 2, wherein the product quality predicting server differentiates information included in the quality index which is transferred to the user terminal, according to the product.

4. The product quality monitoring system as claimed in claim 3, further comprising:

an administrator terminal that administers the product quality predicting server,

wherein the administrator server sets the product quality predicting server to differentiate the information included in the quality index which is transferred to the user terminal, according to the product.

5. The product quality monitoring system as claimed in claim 4, wherein the quality index comprises at least one of a production history, a temperature history, a humidity history, a gas history, freshness, and the number of microorganisms.

6. The product quality monitoring system as claimed in claim 5, wherein the user terminal transmits the identifier of the RFID tag which is included in the QR code, to the product quality predicting server, and the product quality predicting server receives the atmospheric information corresponding to the identifier of the RFID tag from the product distribution history DB.

7. A product quality monitoring system, comprising:

a first packing container in which a product is packed;

an RFID tag which is attached to the first packing container in which the product is packed, and transmits atmospheric history information comprising at least one of temperature and humidity, which has been measured, and an identifier; and

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 link information of a product quality predicting server, and the identifier of the RFID tag.

8. A product quality monitoring system, comprising:

a product distribution history DB which stores atmospheric history information transmitted from an RFID tag, and an identifier of the RFID tag; and

a product quality predicting server which requests the atmospheric history information corresponding to the identifier of the RFID tag which is received from a user terminal, from the product distribution history DB, and calculates at least one of a quality index of a product, and a time when the product has a specific quality index, from the received atmospheric history information, by using a quality predicting algorithm for predicting quality of the product by means of the atmospheric history information,

wherein, the RFID tag is attached to a first packing container in which the product is packed, and the user terminal acquires the identifier of the RFID tag from 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.
