Vending machine
A vending machine is a machine that can automatically pay for goods based on the coins you put in. The most advanced can be paid without paper money, and can be paid by QR code. Vending machines are commonly used equipment for commercial automation. They are not restricted by time or location, and can save manpower and facilitate transactions. It is a brand-new form of commercial retail, also known as a 24-hour micro supermarket.
The smart vending machine is equipped with a payment module, a goods transmission module, a commodity management module, an environmental perception module, a commodity status display module, an advertising management module, and a smart city module inside the body; the commodity management module includes system management and communication, and mobile display portables , Remote vending machine operation terminal composition.
The vending machine can notify personnel to replenish goods in time; it has the function of prompting the specific location of the vending machine when the missing goods are closer; the cloud server can recommend the purchase of goods to the user according to the season, the weather, temperature, and geographic location perceived by the vending machine to enhance the user Experience; a variety of payment functions, convenient and fast.
The control system with integrated circuit STM32 series microcontroller as the core can well meet the above requirements.
