Design of Automatic Beverage Vending Machine Based on CAN Bus

Abstract With the development of times and technological innovation, the economy of our country develops fast and people's quality of life improves continuously。 The popularization and development of Automatic Beverage Vending Machine in China has become a fashion trend。 The study of Automatic Beverage Vending Machine in this thesis is based on ARM technology。 It provides hot or cold drinks and is equipped with multi-payments, so it has been one of the popular products at the present stage。

This thesis introduces the background and actuality of Automatic Beverage Vending Machines。 What’s more, it discusses the difference between it and the Ordinary Beverage Vending Machines in detail and its immeasurable prospects。 This thesis focuses on the design of Automatic Beverage Vending Machine。 Then, it validates the design result through experimental analysis。 The hardware circuit of Beverage Vending Machines uses the key technology of ARM kernel, and the core of this system is ARM chips, which is matched with associated peripheral circuits in hardware circuit architecture design and the design of functional modules。 The main function of software and hardware’s design includes providing hot or cold drinks, using cash payment, RF card or SMS payment and the realization of CAN communication mode。 If the machine breaks down or out of stock, it will provide related tips and report for the switchboard system。
