Problems solved by technology

Therefore, checkout has become a big problem. Sometimes it takes half an hour to checkout in the supermarket, which brings a lot of inconvenience to people’s lives; to bring customers a perfect shopping experience, it is necessary to increase cashiers, and manual wages occupy a large Big costs put a lot of pressure on supermarkets
After exploration, it is found that proper improvement of the shopping cart can alleviate the above problems to a certain extent, but the improvement of the shopping cart only stays in the improvement of the structure of the shopping cart, and the functions of the shopping cart such as independent payment are still not realized, so that Unable to solve the checkout queue problem

Embodiment 1

[0055] Based on the basic working principle of RFID technology: after the electronic tag enters the magnetic field, it receives the radio frequency signal sent by the RFID identification antenna 2, and sends out the product information (passive tag or passive tag) stored in the chip by virtue of the energy obtained by the induced current. Or the tag actively sends a signal of a certain frequency (active tag or active tag), and the RFID identification antenna 2 reads and decodes the information, and then sends it to the microprocessor 3 for relevant data processing.

[0056] In the present invention, when the customer selects the product and puts it in the shopping cart, the electronic tag on the product immediately enters the magnetic field formed by the RFID identification antenna 2 surrounding the car body 6, and the RFID identification antenna 2 reads the electronic tag carried Commodity information: Here, by setting the microprocessor 3, adjusting the reading frequency of t...

Embodiment 2

[0063] After the microprocessor 3 receives the commodity information, the general commodity information includes at least the commodity name, commodity unit price and commodity total price; after the microprocessor receives the information, it classifies and summarizes according to the commodity name,

[0064] Because the RFID identification antenna 2 continues to identify with a certain frequency, the commodity information obtained by the microprocessor 3 continues to be updated. At this time, the received commodity information is divided into two types, one is to continuously receive the same commodity information; It is historical commodity information; the other is that the information currently received also includes new commodity information, which is called real-time commodity information; the microprocessor 3 pre-stores the commodity information acquired for the first time, which is hereinafter referred to as pre-stored information,

[0065] Specifically, the microproce...

Embodiment 3

[0078] Because the display screen is a touch screen 4, it can be implemented by implanting a commonly used input method program in the microprocessor 3, and the spelling of the input command; because the input command at least includes: a query command of the commodity, a position command of the commodity, a browsing command, and a settlement command ; Among them, the realization process of commodity query command, commodity location command and browsing command is that the common input method program contains common fonts, and the common input method fonts display relevant commodity information according to keywords.

[0079] The specific execution process of the settlement instruction is that the settlement button is displayed on the touch screen 4, and when the loop sensor 9 detects the shopping cart, the roadside unit 8 performs microwave communication with the vehicle-mounted unit 1 installed on the shopping cart 6 to obtain the vehicle-mounted unit 1, and upload the bindi...

Abstract

The present invention provides a smart shopping cart based on RFID, a shopping system based on RFID and an application method thereof. The smart shopping card comprises a cart body, and a touch screen, a microprocessor, a vehicle unit, a RFID identification antenna and a storage battery installed on the cart body; the storage battery, the RFID identification antenna and the vehicle unit are connected with the microprocessor; and the shopping system includes the smart shopping cart, a roadside unit, a loop sensor and a control center. The smart shopping cart based on RFID, the shopping system based on RFID and the application method thereof employ the vehicle unit, the roadside unit and the loop sensor for cooperation to make the payment process simple, and convenient and rapid compared to the traditional POS and cash payment; and moreover, through adoption of the RFID identification technology, the smart shopping cart based on RFID, the shopping system based on RFID and the application method thereof realize the automatic identification of goods information with no need for manually inputting numbers of goods and performing laser scanning so as to improve the efficiency.

Description

technical field [0001] The invention relates to the technical field of the electronic internet of things, in particular to an RFID-based smart shopping cart, a shopping system and a usage method. Background technique [0002] Supermarkets As we all know, people habitually shop in supermarkets, which brings a lot of convenience to people's lives. However, with the rapid development of the country's economy, people's living standards continue to improve, people's needs are gradually increasing, and the flow of people in supermarkets continues. increase, especially during holidays. Therefore, checkout has become a big problem. Sometimes it takes half an hour to checkout in the supermarket, which brings a lot of inconvenience to people’s lives; to bring customers a perfect shopping experience, it is necessary to increase cashiers, and manual wages occupy a large The high cost has brought great pressure to the supermarket. After exploration, it is found that proper improvement ...
