Embodiment Construction

[0011] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0012] Such as figure 1 As shown, the hardware structure of the supermarket-keyboard checkout, product update and supervision anti-theft positioning system includes the following parts: RFID tags, reader units, inventory checkout equipment and background servers.

[0013] According to the size of the supermarket, several reader units are deployed inside the supermarket to ensure that the range scanned by the reader unit can cover the entire supermarket. Paste RFID tags on all the goods in the supermarket, write the information of the goods (price, serial number, etc.) After the goods are placed, ...

Abstract

The invention discloses an RFID-based settlement and inventory and positioning and antitheft system comprising multiple RFID tags which are adhered on goods or the external packaging of the goods, a reader-writer unit, inventory and settlement equipment and a background server. The reader-writer unit comprises a locator, and a Zigbee module and an RFID reader-writer which are connected with the locator. One end of each RFID tag is connected with the RFID reader-writer, and the other end is connected with the inventory and settlement equipment. The other end of the inventory and settlement equipment is connected with the background server. Easy one-key settlement, rapid recalling of the goods and prevention of mistaken taking and placing and stealing can be realized so that the efficiency of supermarket management can be greatly enhanced and the pressure of supermarket management personnel can be reduced, the inconvenience of the conventional supermarket mode can be eliminated, management and operation of the supermarket can be greatly facilitated by the internet of things technology and thus the system is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an RFID (Radio Frequency Identification, radio frequency identification)-based checkout and positioning anti-theft system. Background technique [0002] At present, in addition to the ordinary manual settlement, traditional supermarkets mostly use bar codes to settle goods. Both of them are more labor-intensive and may cause omissions and errors, resulting in unnecessary losses. In supermarkets, some refrigerated foods often occur due to customers’ mishandling and misplacing, and the salesperson cannot find them in time due to reasons such as time and energy, which leads to losses. When the supermarket wants to find a certain product for some reason, it often costs more For a long time, using the precise positioning of passive sensing RFID can easily and quickly find the goods and avoid the loss caused by the random handling of the goods, so that the use of the cha...
