The article presents the architecture and operation principles of the system for collecting and analyzing information from strain gauges. These systems are used to determine the equipment performance for transporting a variety of materials. In particular, they are used to control the movement of bulk materials mixtures components. For such technological processes, it is fundamentally important to ensure constant flows intensity. The paper identifies three variants of sensor connection schemes, analyzes their advantages and disadvantages. It is established that the structure “one ADC – several sensors” allows to reduce equipment costs and at the same time to provide the minimum parameters influence of a transmission line on a useful sensor signal. The “one-to-one” scheme provides the connection of each sensor to its own ADC. “Circuit with multiplexer” allows to increase the number of sensors connected to one ADC. It is established that the best option in terms of reducing the interference effects on the analog signal and the cost of creating a system is the scheme “one ADC – several sensors”. The algorithm of information transfer from ADC to microcontroller (MC) is analysed. It is calculated that HX711 ADC chips provide the maximum data rate of 18.5 values/s. It is proposed to transfer data between the MC and the server using the TCP protocol because it avoids data loss and provides the necessary data transfer speed. The structure and formats of data that are transmitted from the mass sensor to the ADC, microcontroller, web server and database are proposed. The main speed, design parameters, advantages and disadvantages of wired and wireless data network between MK and the server are determined. Recommendations for the design of such a network depending on the characteristics of the premises in which the data collection system will be used have been developed.

The paper presents the architecture of the control and statistical data collection system for solar thermal collectors, describing its operating principle and analysis of individual elements, in order to anticipate possible problems and find their solutions. Expanding functionality of the controller of solar thermal collector with online features one can collect data on solar thermal collectors performance in different regions. The paper describes the structure diagram, according to which the system will register operational parameters of the heating system and weather conditions. Data transfer mode, which allows avoiding instant database server load is offered. It is shown, that the simulation of the solar thermal collector operating cycle and optimization of recorded data stream allows over 14 times to reduce the amount of transferred data.

A high-speed data collection and transfer system is designed in this paper. The hardware system is based on EZ-USB FX2 and high speed A/D sampling model based on MAX1198. The frame of hardware is discussed in details. Finally, the solution of software and the firmware flow are provided. The designed system has many advantages such as high-speed, plug and play, easiness to use and expand. It can be used for reference in universal research of real-time and high-speed data transfer system.
