The presented thesis describes the development of a program and a control system
for automatization of the room. It contains description of the tools I used to build the
program and the system, a description of mathematical models for calculating indoor
air temperature and carbon dioxide concentration, which I then used for control
purposes, a description of the controllers used and a description of the program and
the control system itself.
The developed program and control system could be used on an actual
programmable logic controller. Since I did not have a physical controller, I designed
the project on the simulation level, using the Siemens PLCSim software tool.
In addition to internal temperature and concentration of carbon dioxide control, the
system also allows the control of some other elements in the room, which are usually
found in smart home systems, e.g., lights and blinds. The control system is operated
using a Siemens user panel that could complement the controller.
The thesis presents a working system that successfully controls the internal
temperature by heating or cooling and the carbon dioxide concentration through
passive ventilation; it also enables the management of all the other listed elements
and the monitoring and management of the system via the user interface.
