vending machine

In this review article for a smart vending refrigerator, the contours of the future device are thought out and outlined and all its advantages are described. This device will be controlled using Computer Vision and some other features. The main control unit will be Raspberry PI, since it is the best for this device. Also, a web application was developed in which the user registers, and the applica- tion itself transmits the user's information through an API that will be developed to communicate with the web server, and the web server will store this information.

The article considers architecture and algorithms of vending machines. Given of criteria to choosing a microcontroller for creating vending machine. Analyzes hardware interfaces used in vending technology. Shows advantages of using of AES and CRC hardware accelerators.

The article investigates energy consumption of vending machine. Considered industrial design and analyzed energy consumption of machine’s key components. Suggested alternative components that reduce energy consumption. Suggested using of alternative power sources. Recommended a complex approach to issue of energy consumption optimization.
