Intelligent settlement shopping cart system with autonomous tracking function

Abstract

The invention belongs to the technical fields of intelligent control, wireless communication and RFID (radio frequency identification) and particularly relates to an intelligent settlement shopping cart system with an autonomous tracking function. A small controllable direct-current motor (2) is controlled by an MCU (micro control unit) (1), a pressure weighting sensor (3) senses a weight of a shopping cart body, and an RFID radio-frequency card is carried by a consumer and provides a signal source for shopping cart identification; a camera (5) provides a barrier-free path for autonomous movement of a shopping cart, an RFID reader (4), a UnionPay card reader (9) and a barcode scanner (8) are mounted on the shopping cart, a touch display screen (7) is used for man-machine interaction with the consumer, and a wireless transceiver (6) realizes real-time communication of the shopping cart with a supermarket commodity information background server. Two major functions of autonomous tracking and intelligent settlement of the shopping cart are controlled to be realized by the MCU (1). Physical strength consumed for pushing the shopping cart with hands is omitted, the process of consumption settlement is simplified, and shopping efficiency of consumers is increased greatly.

Description

technical field [0001] The invention belongs to the technical fields of intelligent control, wireless communication and radio frequency identification, and in particular relates to an intelligent settlement shopping cart system with an autonomous tracking function. Background technique [0002] The shopping carts currently used in the vast majority of large supermarkets are traditional hand-push shopping carts. This purely mechanical, non-autonomous shopping cart, although it brings convenience to consumers for hands-free shopping, Some physical strength is saved. However, when consumers buy more items and pile up the entire shopping cart, it still takes a lot of physical strength to push the shopping cart full of goods, and it also increases the difficulty of pushing the shopping cart to turn. [0003] The traditional hand-push shopping cart only provides the carrier for the purchased items for consumers. Consumers can push the shopping cart to find the items they need acc...

AI Technical Summary

Problems solved by technology

Consumers can push the shopping cart to find the items they need according to the pre-booked shopping list, and put them in the shopping cart after finding them. Consumers will unconsciously put items they don’t need into the shopping cart due to various reasons such as the good feeling of shopping, unknowingly increasing the shopping budget, but consumers have no idea about the total price of all the items they choose. This increases the possibility of final settlement troubles. For example, when consumers buy more items but have insufficient funds, they must choose to give up certain items, causing unnecessary embarrassment.

[0004] In addition, during weekends or holidays, people's shopping enthusiasm is high, and various large supermarkets are crowded with enthusiastic shoppers, but the supermarkets only set up limited checkout counters at the exits, and people have to wait in long queues for checkout. In the case of a long queue, it may even take half an hour to wait, which not only wastes the shopping time of consumers, affects the shopping mood, but also hinders the further improvement of the sales volume of supermarket goods
