Method for generating payable bill and matching method for payable bills and paid bills

Abstract

The invention relates to the technical field of self-service vending, in particular to a method for generating a payable bill and a matching method for payable bills and paid bills. The method for generating a payable bill includes the following steps: acquiring weight bearing data of a bearing plate for carrying commodities; obtaining the type and quantity of commodities of which the state changes based on the weight bearing data and a pre-stored commodity list, wherein the commodity list records the type and quantity of commodities placed on the bearing plate and the weight value of each commodity in each type of commodities; and generating a payable bill based on the type and quantity of commodities and preset unit prices of commodities. The technical scheme has the following beneficialtechnical effects: an efficient anti-theft reverse investigation means is provided for businesses during self-service purchase by users; and self-service operation in many industries can be promoted,and the number of workers can be reduced. Low-cost and light equipment can be quickly deployed in a large scale.

Description

technical field [0001] The invention relates to the technical fields of machine vision, intelligent equipment, and unmanned vending, and in particular to a method for generating bills payable, a method for matching bills payable and bills paid, and an anti-theft method for judging suspected theft of bills payable and bills paid after matching. , An anti-theft method based on a self-service vending system. Background technique [0002] With the development of unmanned vending technology, more and more self-service vending methods have emerged one after another. [0003] In the field of self-service vending machines, from the initial self-service vending machines (for example: self-service beverage machines, self-service snack machines, self-service adult products machines) that can only be sold with individual packaging and sold in units of goods, it has developed to be able to sell products without Self-service vending machines that are individually packaged and sold in uni...

AI Technical Summary

Problems solved by technology

But the disadvantages are: on the one hand: due to the limited space of the vending machine, only a small amount of goods can be provided; The need to sell goods at scale

However, the post-event forensics process is extremely inefficient and cannot effectively support the application of this model
