Self-service shopping system and control method thereof

Abstract

The invention discloses a self-service shopping system and a control method thereof. The self-service shopping system comprises a plurality of supermarket checkout terminals arranged at the checkout counter and microprocessors arranged on shopping carts. A barcode scanning module and a button module are connected onto an input end group of each microprocessor; a wireless transmission module, a display module, a voice module and an RFID (radio frequency identification) tag are connected onto an output end group of each microprocessor. The first input ends of the supermarket checkout terminals are connected with wireless receiving modules adaptive to the wireless transmission modules, and the second input ends of the supermarket checkout terminals are connected with RFID recognizers adaptive to the RFID tags. The output ends of the supermarket checkout terminals are connected with printers. The self-service shopping system has the remarkable advantages of being capable of achieving self-service shopping, saving queuing time for customers, greatly improves the work efficiency of cashiers in the supermarkets, and is low in cost and convenient to popularize as the system is based on the existing commodity bar codes.

Description

technical field [0001] The invention relates to the technical field of self-service shopping, in particular to a self-service shopping system and a control method thereof. Background technique [0002] At present, most cash registers in supermarkets are collected manually. This is due to the limitation of barcode technology used in supermarkets. Because barcode technology must use contact reading and cannot identify multiple tags at the same time, a cash register is required. Scan the barcode of the item one by one, and finally display the total amount of the item and charge the corresponding fee. This not only wastes customer time, but also reduces the efficiency and service quality of the supermarket. In the long run, it will affect the economic benefits of supermarkets. [0003] With the advent of the Internet of Things era, people have proposed a supermarket intelligent settlement system based on RFID. First of all, all suppliers in the supermarket must affix RFID tag...

AI Technical Summary

Problems solved by technology

[0004] However, whether this method is foreign or domestic, only a few supermarkets are doing pilot operations, and there is no plan to popularize this RFID-based supermarket intelligent settlement system.

The main reason is that the cost of electronic tags is too high, and the labor cost of pasting labels is too expensive; in addition, in the special environment of supermarkets, RFID still has some technical defects. Poor recognition ability of individual product labels

In general, the application of RFID in supermarket self-service shopping is not yet mature and cannot be applied on a large scale
