An unattended supermarket settlement method based on conductive ink pressure sensor

Abstract

The invention provides an unattended supermarket settlement method based on a conductive ink pressure sensor. The film pressure sensor is used to detect changes in the weight of customers and goods in real time. The customer obtains the unique identification of the customer at the entrance area, and the background server compares the unique identification of the customer with the initial weight of the customer. Carry out association and realize customer positioning, the background server determines the goods taken by the customer according to the change of customer weight data and product weight data and updates the settlement list, and finally deducts the settlement fee according to the settlement list to complete the shopping behavior. The unattended supermarket settlement method based on the conductive ink pressure sensor provided by the present invention is ingenious in conception, low in cost, convenient in operation, simple in required algorithm, low in error rate, can meet the needs of a large number of customers shopping at the same time, and meet the needs of bulk goods. Settlement needs, suitable for all kinds of large, medium and small supermarkets.

Description

technical field [0001] The invention relates to an unattended supermarket settlement method based on a conductive ink pressure sensor, which belongs to the field of Internet information technology. Background technique [0002] Since entering the 21st century, with the rapid development of social economy and the accelerated pace of life, my country's offline retail industry is being strongly impacted by the Internet era. Now with e-commerce and well-developed logistics, more and more people are used to Shopping at home. In 2017, the entire retail industry has been shrouded in haze. Due to factors such as uncompetitive prices, capital / personnel / management efficiency, and weak domestic consumption in China, traditional supermarkets have not only seen repeated declines in operating performance, but also frequently reported store closures. On-duty supermarkets have become a major trend in offline shopping. [0003] At present, many units have been involved in the research and d...

Problems solved by technology

[0004] (1) Ma Yun’s Hangzhou unmanned supermarket adopts the scheme of pasting RFID tags on each product combined with visual sensors to prevent theft, and customers take the products to settle their own settlements; however, RFID-based unmanned supermarkets need to consume a lot of RFID tags. Although the RFID tags themselves cost Inexpensive, but for the number of commodities in the supermarket, the amount used is huge and cannot be recycled. At the same time, the input and pasting of RFID tag data before putting on the shelves will increase the labor cost;

[0005] (2) The Amazon Go convenience store launched by Amazon in the United States uses a large number of cameras combined with a variety of smart technologies to calculate who took which item by sensing the relative position between people and the shelf and the movement of items on the shelf. Final settlement; this type of unmanned supermarket based on visual tracking technology requires a large number of cameras, which has a high cost and relies on more advanced visual tracking algorithms. For customers with similar looks or clothing, the error rate is obviously increased, and the practicability is not good. powerful;

[0006] (3) F5 Future Store has designed an unattended convenience store relying on robotic arms and computers instead of manpower. In this mode, a convenience store of about 30-60 square meters consists of 4 machines, which are respectively Cargo machines (selling fast-moving consumer goods such as beverages, snacks, and daily necessities), beverage vending machines, fresh food vending machines (car noodles, fish and egg foods) and automatic table cleaning. The core technology is robotic arms and intelligent warehouse management. Customers can complete shopping through three purchase methods: (a) customers place an order through the mobile terminal, and then pick up the goods at a nearby store; (b) place an order through the self-service terminal in the store, and pick up the goods after the machine is shipped; Scan the code on the wall to place an order, and pick up the goods after the machine is shipped; F5 Future Store has imposed strict restrictions on the customer's shopping process. For customers, the shopping process is very different from the traditional shopping process in the supermarket. On the contrary, it is closer to the online shopping experience. However, it is faster to pick up goods, and because it strongly relies on mechanical devices such as robotic arms, high cost and large space constraints, this model is only suitable for small-scale convenience stores

[0007] In addition to the above-mentioned defects, the existing unmanned supermarket solutions also have a fatal weakness: they can only realize the sale of fully packaged goods, but they cannot solve the problem of weighing bulk goods. Meet the sales needs of unattended supermarkets
