Description

Unmanned automatic weighing and price calculating counter system

Technical Field

The invention belongs to the technical field of automatic vending and intelligent instruments, and particularly relates to an unmanned automatic weighing and pricing sales counter.

Background

Amazon opens a cashier-free concept grocery store Amazon Go to the seattle public on month 1, 22 of 2018, and a customer only needs to download Amazon Go APP, and after the store entrance is scanned successfully, the customer can enter the store to start shopping. Cameras distributed on the ceiling inside the shopping process store track and record the shopping process of each consumer, and record the commodity shelf consumed by the consumer and also the pressure sensor for further detection and verification of whether the information of the consumer product is accurate,

but with today's importance of personal privacy and the development of modern technology, supermarkets will obtain excessive customer information such as which merchandise the consumer has purchase impulse and possibility for, and the consumer's corresponding consumer water products etc., which will make the consumer have no privacy. The fresh fruits and vegetables sold in the supermarket are packaged and weighed well, and the current consumer is not matched with the personalized demand, so that the shopping demand of the current consumer cannot be met.

In the field of weighing, a traditional supermarket needs a customer to purchase a number commodity, then the commodity is weighed and charged to a weighing platform under the assistance of staff, and then the commodity is settled to a counter. A new solution is proposed in patent CN 106959149A, in which the customer places the purchased bulk product on top of an electronic scale for automatic weighing and pricing of fruits and vegetables, which can price different goods by their corresponding weights, but by its technical method it is shown that the cost must be increased if the accuracy is improved, but that the accuracy is not high enough, and it is not possible to bill accurately.

The operation is not simple enough for consumers and shops, and cheating of consumers cannot be avoided, and accurate pricing cannot be achieved if goods are superimposed.

The field of unmanned sales counter, along with the development of the times, the consumer increasingly attaches more importance to time, and various forms of self-service sales counter appear on the market, can provide self-service purchase of fruit vegetables for the consumer, and can directly provide juice service, the intelligent vending machine of internet commodity that proposes in patent CN 205230187U, the vending machine that this scheme described has fine theftproof protection, but the user can't select and change in like commodity, and the type is not abundant purchasing operation more loaded down with trivial details and expensive.

In the field of unmanned containers, a novel table-type weighing shelf is proposed in patent CN 203693111U, the shelf is of a multi-layer vertical structure according to description, and weighing sensors are distributed on a weighing substrate of the shelf. According to the technical description, the scheme is an improvement scheme aiming at the market and warehouse management and is a scheme for assisting in manually managing the product quantity. The payment module and the identity recognition function are not arranged, and meanwhile, each box body is required to be provided with a weighing sensor correspondingly, so that the cost is high, the maintenance is complicated, the shopping flow of the consumer is not influenced, and the shopping time of the consumer is shortened. Therefore, the scheme is that the user also needs to pay after weighing and packing the bulk commodity and the fruit, and the requirements of consumers on shortening shopping time and bringing convenience to purchasing objects cannot be met. Patent CN 105678925A proposes a self-service vending system and method, according to which, according to the description, an independent display basket is provided for all kinds of goods, an independent weighing sensor is provided for the display basket, and when a user makes a purchase, the user carries the shopping basket to put the goods into the shopping basket system, so that the price and weight information of the goods can be obtained. The scheme is a scheme aiming at the vegetable market, so that shopping is facilitated to a certain extent, but the scheme cost and the maintenance cost are higher than those of CN 203693111U, and the complexity is further improved. Meanwhile, when a plurality of consumers simultaneously take and put the commodities with the same quality in different display baskets into the shopping basket, the scheme cannot judge the purchaser of the corresponding commodity. Meanwhile, the scheme cannot be applied to unmanned sales counter because no anti-theft protection measures are provided, and therefore, the scheme cannot completely meet further requirements of the market on products.

In the field of image recognition, patent CN 107122730A proposes an automatic pricing method for a self-selected restaurant based on a computer vision technology, and according to the description of the method, learning and recognition are performed on all dish example pictures through deep learning and metric learning. To achieve the effect of distinguishing dishes similar to manual work. According to the scheme, a great deal of learning needs to be performed on all dishes in advance, the operation capability of the system is required to be high, the requirements of the market on low cost and universality cannot be met, and the operation is complicated.
