Vending method based on goods identification and vending machine

Abstract

The invention discloses a vending method based on goods identification and a vending machine. The method comprises the following steps: detecting the weight change on goods placement boards by a weight sensor when detecting that the door of the vending machine is opened; controlling a camera in the vending machine to take a picture when the weight change is detected, so as to obtain an internal picture; and identifying the internal picture, when a tag is identified in the internal picture, determining the category of the goods according to the tag, and using the weight sensor to calculate thecategory and quantity of the goods taken out or put in. According to the vending method based on goods identification and the vending machine, the cost of operating an open self-service vending machine is greatly reduced by replacing the RFID tag with a custom tag, capturing the tag on the goods with the camera and calculating the weight change to summarize and check the category and quantity of the goods.

Description

technical field [0001] The invention relates to the technical field of automatic vending applications, in particular to an automatic vending method and an automatic vending machine based on item identification. Background technique [0002] With the development and progress of science and technology, there are more and more places where vending machines are used. Vending machines are common equipment for commercial automation. They are not limited by time and place. There is less manual management, which can save manpower and facilitate consumption. Traders get access to items anytime, anywhere. [0003] At present, the existing vending machines on the market mainly use RFID (Radio Frequency Identification, radio frequency identification technology, also known as radio frequency identification, which is a communication technology that can identify specific targets through radio signals and read and write related data without identification. Establish mechanical or optical c...

Problems solved by technology

[0003] At present, the existing vending machines on the market mainly use RFID (Radio Frequency Identification, radio frequency identification technology, also known as radio frequency identification, which is a communication technology that can identify specific targets through radio signals and read and write related data without identification. Establish mechanical or optical contact between the system and a specific target) to identify the category and quantity of items taken out and put in by the user (consumer), then each item will have a corresponding RFID tag (ie radio frequency tag) representing itself, The radio frequency tag is the physical carrier of the electronic product code (EPC). It is attached to trackable items and can be circulated globally and identified and read and written. However, the price of RFID tags is relatively expensive. Generally, an RFID tag costs 0.2-0.5 yuan The cost is not cost-effective for long-term operation of vending machines; in addition, the existing vending machines generally allow users to view and select items through transparent cabinets, and cannot directly open the door to select items, and the operation is more intuitive.
