Refrigerator food material management system based on near field communication technology

Abstract

The embodiment of the invention provides a refrigerator food material management system based on the near field communication technology. The system comprises a near field communication tag, a data processing module, a near field communication reader, a voice module, a data storage module and a network module. The near field communication reader, the voice module, the data storage module and the network module are all connected to the data processing module. According to the invention, the NFC reader is arranged on the outer surface of the refrigerator door body, the NFC reader can identify all the NFC tags, and compared with the prior art that one RFID reader needs to be arranged for each bin, the hardware cost can be reduced. And the NFC reader is adopted, and the NFC technology is adopted for near field communication, so that compared with the RFID technology, the problem of bin crossing can be avoided, and the information accuracy is improved.

Description

technical field [0001] One or more embodiments of this specification relate to the field of smart refrigerators, and in particular to a refrigerator food management system based on near field communication technology. Background technique [0002] With the development of smart technology, a solution for managing ingredients in a refrigerator through radio frequency identification (Radio Frequency Identification, abbreviated as RFID) technology has been applied to smart refrigerators. The scheme of using RFID technology to manage refrigerator ingredients is roughly as follows: the type, name, shelf life and other information of the ingredients are pre-recorded on the RFID tags, such as figure 1 As shown, each warehouse is equipped with an RFID reader. When the ingredients need to be stored, find the corresponding RFID tags of the ingredients and put them in the refrigerator together with the ingredients. The RFID reader in the warehouse will scan the RFID tags to get the inf...

Problems solved by technology

[0003] Although the use of RFID tags can realize the intelligent management of refrigerator ingredients, but this method also has some disadvantages: 1. The information of ingredients needs to be preset in the RFID tags. To store multiple copies of the same type of ingredients, multiple copies of the same type of labels are required, and a large number of labels requires a certain cost; When preparing ingredients, it is necessary to search for the tags corresponding to the current ingredients from a large number of tags, which increases the difficulty for users to manage tags; 3. In order to obtain the storage location of ingredients, RFID readers need to be installed in each warehouse, which increases the The manufacturing cost of the refrigerator; 4. The information of the ingredients is preset in the RFID tag. Due to the long communication distance of the RFID technology, the RFID reader in the refrigerator compartment may recognize the labels in other compartments or outside the compartment, resulting in errors in the management of ingredients. information
