Abstract

The invention provides an automatic weighing and settlement system comprising a plurality of shopping shelves used for holding commodities, and a weighing device and a settlement device. The weighingdevice is used for weighing the commodities in the shopping shelves. The settlement device comprises a communication module, a storage module, a settlement module and a display module, wherein the communication module is in communication connection with the weighing device, the storage module is used for storing the unit prices of the commodities in the shopping shelves and weight data of the commodities, and the settlement module is used for determining the change quantities of the weight of the commodities in the shopping shelves, calculating the price of each taken commodity by multiplyingthe corresponding change quantity by the unit price of the corresponding commodity, and finally adding up the prices of all the taken commodities to obtain a total settlement price, wherein the changequantities are the weight of taken commodities. During shopping, commodities can be placed together and split packaging and weighing is not needed; after commodities are taken away, the weighing device automatically transmits reduction weight data to the settlement device and the settlement device performs calculation automatically, so that complex shopping processes are simplified and self-service shopping is realized conveniently and rapidly.

Description

Technical field [0001] The invention relates to the technical field of self-service shopping, in particular to an automatic weighing and settlement system. Background technique [0002] At present, when buying vegetables, fruits, fructose, biscuits and other goods in supermarkets, the method of bulk weighing is generally adopted, but this method of bulk weighing has the following problems: [0003] 1.

In order to prevent price errors caused by mixed weighing, workers need to manually identify and sort them, and then weigh them one by one. Before weighing, they must manually enter the unit price, which is cumbersome and labor-intensive; [0005] 3. After weighing, it needs to be sealed and packaged. When shoppers need to redu...

AI Technical Summary

Problems solved by technology

[0003] 1. When shopping, it needs to be packed and taken in plastic bags, and they cannot be mixed and placed in the shopping basket, which has caused great trouble to shoppers. It also needs to waste a lot of plastic bags for packing, polluting the environment

[0004] 2. In order to prevent the price error caused by mixed weighing, the staff needs to manually distinguish and sort the weighing, and then weigh one by one. Before weighing, the unit price must be manually input, which is cumbersome and labor-intensive;

[0005] 3. After weighing, it needs to be sealed and packaged. When shoppers need to reduce or increase the goods, they need to destroy the plastic bag before proceeding, and they need to weigh again to obtain the price barcode, which is troublesome to operate;

[0006] 4. During settlement, it is necessary to scan the price barcode one by one to make a cost-effective payment before making payment, which is cumbersome to operate and poor in self-service
