Automated system for operational analysis the energy efficiency of public buildings heating in Donetsk city

Automated system for operational analysis the energy efficiency of public buildings heating in Donetsk city was carried out under an agreement with the Donetsk City Council for the scientific work No. 08-198 "Automation of energy consumption metering of public sector objects", and scientific work No. 09-275 "Development of an automated energy consumption metering system" .
An automated system consists of hardware and software.
The composition of the measuring post includes:
  • analogue air temperature sensors;
  • heat meters;
  • controller with integrated analog-to-digital converter;
  • industrial minicomputer;
  • ADSL modem.
The system was installed in school number 66 of the Kuibyshev district of the city of Donetsk.
 Temperature sensors LM335 (in box with a wireless controller).

Software of an industrial minicomputer in the mode of receiving data from room temperature sensors

Heat meter

Water temperature sensor

From the temperature sensors of automated posts, the analog signal is fed to the inputs of the microcontroller's ADC. The signal is digitized and using the file exchange of specified data, transmitted to the FTP-server of the energy management department. And from FTP-server data sends to database.
Database

Automated workplace of the energy manager
The information used in the automated workplace of the energy manager of the system for analyzing the energy efficiency of heating of public buildings is necessary to realize the following functional capabilities:

  • input, modification and processing of administrative, territorial, legal information of public buildings;
  • entering and changing additional information related to energy supply, energy consumption and heat supply of buildings;
  • input, change and processing of information about connected communications, supply of energy resources and temperature regime of public buildings;
  • input, change and processing of information about the connected energy meters of public buildings;
  • manual entry and maintenance of databases of readings from energy meters;
  • automatic data collection of readings from energy meters;
  • generation and presentation to the user of data on energy consumption in tabular or graphical form;
  • generation of regulatory reports and analysis forms.

System are presented in many exhibitions. System are a part of dissertation

2D CNC engraver controlled by LabVIEW

Exhibition of scientific works of students "NTTM MAN-2017". Under my leadership, students won the third place among the collective developments. The guys presented the design of 2D CNC engraver controlled by LabVIEW. We used this engraver for summer practice work in my department of computer design and modelling. And we have results! There is a some examples. 

Automation of shooting a physical stationary object

The photo-shooting system for the electronic museum's  materials was automated by Moskalyuk Taras - a student of the Computer Science and Technology Faculty, under the my guidance. Automation is performed using the Lego NXT technology, which significantly approximates the end of work and improves the quality of the footage. The new shooting technology allows to expand the possibilities of creating three-dimensional images, up to 180 images per model, without complicating the process of shooting and processing raw materials. Science article was written .

LabVIEW based mathematical model of building’s heat consumption with non-stationary processes

In this article , the issue of non-stationary processes heat consumption by public buildings for the energy efficiency analysis in heating buildings is being considered. It is justified that the most suitable parameter for adapting the model to the specific building’s conditions is the total heat capacity of everything that is inside the building. As a developed model adaptation’s result there are empirical dependence of total heat capacity has been established for schools. The developed model was used for building’s heating simulation with a cyclically changing load in order to establish the possibility to saving the energy. After passing the preparatory adaptation, the sufficient correspondence of numerical experiments and the practical data on measurement of temperatures are justified. The model was solved using the LabVIEW programming environment. The model is confirmed for schools in Donetsk, for each school, the number of experiments is equal to the number of info
