In the context of digitalization of the most knowledge-intensive sectors of the domestic economy, the development of an industrial training system in the field of electronic instrumentation is of great importance. The key areas of its development with the use of information and communication technologies include the development and improvement of the technological basis for training and retraining of personnel in engineering educational programs. One of the elements of this basis is the service of multi-user remote access via the internet to a high-tech experimental equipment laboratory as a service based on internet of things (IoT) systems. Within the framework of this service, an urgent problem is to increase the functional saturation of automated stands/installations, which is currently characterized by a paucity of scientific research. The purpose of the research is to expand the areas of experimental research carried out in the mode of multiuser remote access based on specialized IoT systems. As a result, a method of multidisciplinary application of specialized IoT systems was developed. This consists of the technical implementation of possibilities for additional research: research into technologies underlying both multi-user distributed measuring and control systems and IoT systems in general; research into technologies used in their end-to-end computer-aided design; research into joint interaction of several geographically distributed automated stands/installations, implemented on the basis of a four level IoT reference architecture. A methodology for the design of multi-user distributed measuring and control systems as specialized IoT systems has also been developed, focused on solving multidisciplinary research problems in an interactive dialogue mode based on single sample of experimental equipment. The methodology mobilizes organizational, technical and methodological support for the process of creating such systems with specified target characteristics. In general, the method and methodology developed open up opportunities for systematically implementing the basic principles of the “Education 4.0” concept in the preparation and retraining of engineering personnel in the field of electronic instrumentation.

The information educational space has become a new organizational and pedagogical system of educational institutions with the potential of open and remote access to educational resources, pedagogical staff’s innovative activities, constant monitoring of students’ knowledge, skills, and interaction of the participants of the educational process. One of the ways of civil protection specialists’ training, retraining and advanced training system modernization is the introduction of innovative pedagogical, information and communication technologies into the educational process.  However, it should be noted that the programs launched at both state and departmental levels did not become mobilizing measures that would allow to avoid the dispersion of intellectual, material and especially financial resources in the context of the formation of a targeted information educational space by focusing efforts on intellectual scientific and pedagogical potential of the educational system. In such a situation, haphazard and normatively unregulated dissemination of teachers’ personal and educational establishments’ websites on altruistic principles using cloud technologies has become quite widespread. The educational institutions of departmental subordination, including the ones in civil protection, as mentioned in the Strategy for reforming the State Emergency System for 2017-2020, did not overlook this problem. The National Strategy for the Education Development until 2021, approved by the Decree of the President of Ukraine dated 26.06.2013 No. 344/2013, is directed to remedy this situation, but the measures implemented are still more declared than stimulating and not aimed at initiating a mechanism that would unite the pedagogical community within the state target project for national information educational space creation. Strategic documents and national education projects are designed, first of all, to support the innovative activity of pedagogical teams and to prepare teachers for work in the information society. Organized by the Human Resources Department, the competition “Creating and Developing Together” became an effective motivational tool for attracting the SESU researchers and pedagogical staff of higher education institutions. Developing the information educational system based on the systematic approach makes it possible to identify the main functional elements in its structure in order to model and describe the processes of each individual element, as well as in their process-functional interrelation. In the paper, the information educational environment is introduced in a purely pragmatic format to train civil protection specialists. It represents a set of artificially created situations which provide basis for educational information transfer and assimilation, professional knowledge accumulation, skills and competences development and, at the same time, the development of personal qualities of this integrated profession.

Introduction: The rapid development of the information society is expressed in the emergence of new models of economic activity, forms of providing educational and social services, scientific activities, etc. оn the basis of constantly improving digital technologies. This, in turn, leads to the emergence of new requirements for knowledge and skills of modern engineers whose preparation is based on various laboratory studies. The modern form of realization of such researches is multi-user remote access from digital educational environment to specialized experimental equipment (laboratory installations/stands/layouts), providing efficient use of this equipment. Purpose: Comparative analysis of methods for increasing the throughput of experimental equipment with multi-user remote access. Methods: Management of user request service procedure based on scheduling algorithms which take into account the functional and parametric content of the processed requests (configuration settings of the object of study, type of measurements taken, parameters of test signals, etc.), as well as the features of the hardware construction. Results: On the basis of the proposed approach for multi-user distributed measuring-control systems the following methods are developed: 1. A method of minimizing control operations which determines the sequence of retrieving jobs from the queue in accordance with the minimum of total control time for all the requests currently in the queue. 2. A method of temporary division of multiple measurements, providing distribution of operations of statistical processing of measurement results between the software on a measuring-control computer and the user terminal. 3. A method of parallelizing functional operations which reduces the time to service the requests by programmatically splitting and concurrently performing the management and measuring operations for queued queries related to different control objects. A comparative analysis of the applied approaches has shown that the most effective, in terms of the cost of equipping a single user workplace, are methods based on managing the process of servicing the user requests. Practical relevance: The developed methods have made it possible to create a number of samples of multi-user distributed measuring-control systems for the automation of educational and scientific experimental researches with a 16–40% lower cost of equipping a workplace and with throughput of 30–50 concurrent users on the basis of one set of specialized experimental equipment.
