Embodiment

[0041] The unmanned vending method based on RFID technology described in the embodiment of the present invention, such as figure 1 shown, including the following steps:

[0042]Step S1. After the last transaction cabinet door was closed, scan the RFID tags corresponding to all the commodities in the unmanned vending cabinet before this transaction, and record the scanning result as A1 collection; Scan the RFID tags corresponding to all the commodities in the unmanned vending cabinet, and record the scanning results as A2 collection; after the door of the transaction cabinet is closed, scan the RFID tags corresponding to all the commodities in the unmanned vending cabinet, and record the scanning results Set for A3;

[0043] It can be understood that the collection described in this embodiment is a whole composed of one or more RFID tags corresponding to commodities as elements. Nongfu Spring (corresponding RFID tag is a), Wahaha (corresponding RFID tag is b), Turkey Noodles ...

Abstract

The present invention relates to the technical field of intelligent equipment. The present invention aims to solve the problem that the existing unmanned vending cabinets are easy to identify mistakes and cause damage to the interests of users. It proposes an unmanned vending method and device based on RFID technology. The method includes: Scan the RFID tags corresponding to all the commodities in the unmanned vending cabinet after the last transaction cabinet door is closed, before this transaction, during this transaction, before the cabinet door is opened, and after this transaction cabinet door is closed, and record The scan results correspond to sets A1, A2, and A3; calculate the union A of set A1 and set A2, the relative complement set B of set A3 with respect to set A, and the relative complement set C1 of set A2 with respect to set A1; according to set B and C1 The price of the goods corresponding to all RFID tags in the collection is settled. The invention performs settlement according to the difference between the price of the commodity purchased by the user and the price of the misidentified commodity, avoids damage to the interests of the user, and is suitable for unmanned vending cabinets.

Description

technical field [0001] The present invention relates to the technical field of smart devices, in particular to an unmanned vending method and device. Background technique [0002] RFID (radio frequency identification) is a non-contact radio frequency identification technology, which automatically identifies the target object and obtains relevant data through radio frequency signals, and the identification work does not require manual intervention. RFID tags are divided into two types: active tags and passive tags. The principle of identification is mainly: after the RFID tag enters the magnetic field, it receives the radio frequency signal sent by the reader, and sends out the product information stored in the chip by virtue of the energy obtained by the induced current (passive tag). tag), or actively send a signal of a certain frequency (active tag), the reader interprets and decodes the information, and sends it to the central information system for corresponding data pro...
