Development of the architecture of the remote access system to educational laboratory equipment using automated solutions

The subject of the study is remote access to Raspberry Pi-based training equipment and remote desktop software. The purpose of the work is to analyze the means of remote control of equipment and develop the architecture of the system of remote access of students to laboratory equipment for the implementation of distance learning. The following tasks are solved in the article: the branches in which application of means of remote access is the most critical are analyzed, among which the special place is occupied by the educational branch; analysis of existing methods of organization of remote access to training equipment was carried out, advantages and disadvantages of each method were allocated; justification is being made for choosing a Raspberry Pi minicomputer as a hardware platform for building remote access systems; describes the architecture of a complex of technical solutions based on Raspberry Pi for remote control of educational laboratory equipment; implementation of applied system of temperature and humidity monitoring using developed approach is described. Research methods include comparative analysis of existing remote control technologies, prototyping and experimental testing of the developed system. The following results were obtained: the feasibility of using the remote desktop approach and AnyDesk software for organizing access was substantiated, a system based on the Raspberry Pi minicomputer for managing equipment and visualizing data was developed, an applied system for monitoring temperature and humidity using Raspberry Pi and AnyDesk was implemented. Conclusions: The proposed approach of using Raspberry Pi and remote desktop software allows students to effectively organize remote access to laboratory equipment from engineering disciplines during distance learning. This solution combines ease of implementation, interaction with real physical equipment and low cost compared to the use of industrial PLCs.
