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 information measurement days, in non-stationary thermal conditions.

This model is a part of dissertation work.

The thermostat in the boiler room

The complex performs automatic control of the boiler houses network with the ability to monitor and adjust the algorithm through the global network. Consists from hardware and software parts. Includes a thermostat in the boiler room and a manager. Thermostat in the boiler room Hardware: The controller is a PC / 104 processor board (2xRS232, LPT, IDE, Ethernet, VGA, keyboard, mouse). ROM - IDE M-Systems 256 Mb flash disk. Sensors - case external temperature sensor (-40:+30°С); contact feed sensor (-5:+100°С), contact sensor of return water (-5:+100°С); Cabinet temperature sensor in the room (-5:+10°C). All sensors are built on thermistors. Analog input - self-made device (4 analog inputs 8kHz -> RS232, galvanic isolation). Discrete output - self-made device (Parallel port -> 8 relays); Power supply, housing, a set of connecting wires. Optionally - a CDMA modem with a directional antenna, a radio modem, a GSM modem, a wired telephone modem. Software : Window...

Starting Work at ITMO University

On the recommendation of colleagues from DevelopLabs , I accepted the offer to teach at ITMO University. Link to my page. I will be teaching computer networks, protocols, IoT, and machine vision. ITMO University is a leading Russian university specializing in information technology, photonics, robotics, and other high-tech fields. Founded in 1900 in St. Petersburg, the university is among the top technical universities in Russia and worldwide. In the QS World University Rankings 2024 , ITMO is ranked in the top 400 , and in the Computer Science & Information Systems category, it is among the top 100 . The university is also renowned for its victories in international programming competitions (ICPC), where it has repeatedly become the world champion. According to the updated QS World University Rankings , ITMO University has maintained its position for the second year in a row and ranks second among Russian universities in computer science .

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.
