Description
The present invention relates to an RFID system for a refrigerator, and more particularly, to an RFID system for a refrigerator, which records additional information on a recordable RFID tag and emits a light emitting unit when searching for an article, thereby easily managing and locating the article stored in the refrigerator. .
In general, RFID (Radio frequency identification) system is a system that can obtain the information of the article by using a tag (tag) attached to the article wirelessly, high recognition rate, contactless recognition media, linkage with other communication networks, high Due to the advantages of scalability, the scope of application of logistics, distribution, and food is expanding.
On the other hand, refrigerators are becoming larger due to changes in consumer electronics manufacturing technology and consumer consumption patterns. Furthermore, refrigerators have been developed into intelligent devices that provide various user convenience functions in conjunction with IT technology.
In particular, in recent years, RFID systems have been applied to determine the existence and shelf life of items being stored without opening the door of the refrigerator.
However, such a conventional RFID system is limited in use because it provides only fixed information according to a tag attached in advance, and since the user does not know the actual position of the article, when a user puts a lot of items in the refrigerator mixed, It is often difficult to find a desired article.
The present invention has been proposed to solve the above problems, and an object of the present invention is to provide an RFID system for a refrigerator that can easily grasp the location and related information of an article stored in the refrigerator.
The present invention for achieving the above object is an RFID tag having a light emitting unit and capable of reading and writing; At least one antenna installed on an inner wall of the refrigerator; And an RFID terminal for recording additional information including article information on the RFID tag, reading identification information of the RFID tag through the at least one antenna, and generating and transmitting a control signal of the light emitting unit. do.
Preferably, the RFID tag includes a communication unit for communicating with the RFID terminal through a tag antenna, a light emitting unit that is turned on according to the control signal, a memory unit for storing the additional information and identification information, and the tag antenna. Determine whether the received information matches the identification information or the additional information stored in the memory unit, perform communication with the RFID terminal, turn on the light emitting unit according to the control signal received from the RFID terminal, and request for recording. And a controller for controlling the stored additional information to be stored in the memory unit.
Preferably, the controller may control the light emitting unit to blink at a predetermined time period.
Preferably, the RFID terminal comprises: an input unit for inputting additional information to be recorded on the RFID tag and item information to be searched; a display unit for displaying additional information received from the RFID tag and displaying a search screen of the article; And a communication unit for communicating with the RFID tag through the at least one antenna, an RFID tag corresponding to the input search object, and transmitting a control signal of the light emitting unit to the corresponding RFID tag, and inputting the additional information. It may include a control unit for controlling to be recorded in the RFID tag.
Preferably, the RFID terminal may further include an output unit connected to an external printer to output article information and additional information of the RFID tag.
Preferably, the RFID terminal can identify the position of the RFID tag according to the strength of the signal received from the antenna arranged in a grid form inside the refrigerator.
The RFID system for a refrigerator according to the present invention records additional information of an article on a recordable RFID tag and emits a light emitting unit when searching for an article, so that not only management of the article stored in the refrigerator but also easy to locate can be used efficiently. There is an effect that can reduce the waste factor by purchasing goods.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
