Abstract

The invention discloses an intelligent refrigerator based on the Internet of Things. A refrigerating space is formed in the refrigerator; multiple supporting plates are arranged in the refrigerating space, and a complete reader antenna body is arranged on the edge of each supporting plate in a surrounding mode; the intelligent refrigerator further comprises a main controller and antenna controllers arranged on the reader antenna bodies in a matching mode, the main controller outputs set power to a power divider, and multiple output ports of the power divider output an average value of the setpower to the multiple antenna controllers in the same phase; and commodities placed on the supporting plates are each provided with a tag, the antenna controllers drive exciting magnetic fields formedby the reader antenna bodies to activate internal circuits of the tags, the multiple antenna controllers simultaneously receive identifies of the tags in the corresponding antenna magnetic field ranges and output the identifies from the tags to the main controller through the power divider in the same phase, and the main controller decodes the identifies. The invention further discloses a refrigerating system. The intelligent refrigerator has the good practicability.
