Vending Machine Design

1. Hardware Design

A vending machine mainly consists of a shell, cargo channels, controller, sensors, payment system, and heating or cooling system. Among these, the controller is the core component responsible for managing all machine operations, including item identification, payment processing, and cargo delivery. Sensors are used to monitor the internal status of the machine, such as item quantity and temperature. The heating or cooling system adjusts the product temperature based on real-time needs.

2. Software Design

The software system of a vending machine is designed for automation and intelligence. It includes modules such as the user interface, payment system, communication system, and database. The user interface handles orders and payment input from users. The communication system enables real-time interaction with users, while the database stores product and user information.

Analysis of Key Technologies

1. Machine Vision Technology

Machine vision technology helps vending machines accurately identify goods and monitor internal conditions. For example, deep learning-based models can analyze images taken inside the machine to determine the type and quantity of items.

2. Internet of Things (IoT) Technology

IoT technology allows vending machines to communicate with users in real-time, enabling them to access item availability and order status at any time. Additionally, IoT enables remote control and management of the vending machines.
