vending

Features of vending cyber physical systems performance after durable exploitation have been examined. Ready-made means of cyber physical systems scaling have been analyzed. Main advantages and disadvantages of a ready system switchover to a third-party developer’s platform have been defined. Means of large databases optimization have been offered. Analytical data that led to the decision to optimize the existing database have been produced. The elements of vending cyber physical system and possible changes in its structure due to the switchover to different platforms have been covered.

In the article review of interfaces and peripheral device protocols for vending machines has been conducted and they have been compared. Based on the peculiarities shown in the comparative characteristic realization of unified program interface for the set of given protocols has been suggested. The stages of interaction between control board and actuators have been described. The structural scheme of interface realization has been shown.

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.

In this work organization and principles of multilevel vending cyber physical systems (VCPS) development have been examined. VCPS purposes and functions on each level as well as interlevel interaction have been described, as well as the classification of vending machines has been offered. The results of analytical system work have been shown graphically.
