Low-power Renewable Possibilities for Geothermal IoT Monitoring Systems

Nowadays, humanity is facing a difficult challenge, because of sustainable energy use and production. One of the major ways to solve this problem is the usage of renewable energy as a sustainable and reliable source of electric power and heat. This trend is also obvious in the field of the Internet of Things (IoT), where research teams are increasingly focusing on renewable energy and its monitoring with IoT. This paper aims to map current research on the use of the Internet of Things with a special focus on use in geothermal applications. Information concerning renewable geothermal energy sources and individual IoT communication technologies is summarized. A basic Bluetooth iBeacon test case is also presented.©2022 IEEE.

Measurements and Elimination of the Electromagnetic Interference in Industry Environments

The paper deals with problems and research of the electromagnetic interference of the technology systems with respect to their functionality and reliability for the reconstruction or installation of modern electronics and modern control systems in the existing technologies in industrial areas. It is becoming ever more important to pay attention to problems of the safe operation of the information systems, the data and the signal flow with the lowest error rates of transmission and elimination of the negative influences of various disturbances and interference. The article describes the modern design, simulation and implementation of the measurement methods of electromagnetic interference in a renovated industrial company in the Czech Republic. Based on the evaluation of the measured parameters and waveforms of signals, measures are suggested to eliminate the electromagnetic interference for reliable operation of control systems. Moreover, the implementation of the developed mathematical simulation model for electromagnetic field is explained

Experiences with the construction of "The Research Polygon" for low potential energy acquisition from rock massive in areas of VSB - Technical University Ostrava-Poruba

Podczas wykonania i obsługi poligonów badawczych na terenie VSB - Uniwersytet Techniczny w Ostrawie autorzy uzyskali doświadczenia, które mogą zostać wykorzystane przy przygotowywaniu podobnych obiektów badawczych. Artykuł omawia doświadczenia zdobyte przy projektowaniu i realizacji dużego poligonu doświadczalnego wykonanego w pobliżu Nowej Auli VSB (największego budynku w Republice Czeskiej ogrzewanego przy użyciu pomp ciepła) i małego poligonu doświadczalnego zlokalizowanego w pobliżu Centrum Bada Energetycznych. Oba poligony wykonano w obrębie campusu VSB - Uniwersytet Techniczny w Ostrawie.During realization and operating of Research Polygons in areas of VSB - Technical University of Ostrava and AGH Kraków authors took many experiences which can be used for next construction of similar. This article will discuss experiences from realization and construction of the Large Research Polygon near the building Nova Aula (the biggest building in the Czech Republic which use heat pumps) and Small Research Polygon near the building Research Energetic Centrum, both in campus of VSB - Technical University of Ostrava, and also the results of the similar research polygon situated in the area of Drilling, Oil-Gas Faculty AGH Kraków

Evaluation of influence of climate conditions on rock mass energy balance in the research area of VSB - TU Ostrava

VSB - Uniwersytet Techniczny w Ostrawie posiada unikalną możliwość badania zmian temperatury w górotworze dla długotrwałego działania pomp ciepła. Nowy budynek Audytorium jest nie tylko największym obiektem w Republice Czeskiej, ale także w Europie Środkowej, ogrzewanym przez system pomp ciepła. Wraz z systemem otworów technologicznych pozyskujących ciepło z górotworu odwiercono również badawcze otwory monitorujące, które kontrolują zmiany temperatury w otaczającym górotworze podczas eksploatacji systemu grzewczego. System monitorowania zlokalizowany na obszarze działania otworów technologicznych nazywa się Dużym Poligonem Badawczym. VSB-TU posiada drugi systemu badawczego nazywany Małym Poligonem Badawczym i lokalizacją w pobliżu budynku Centrum Badań Energetycznych (CBE). Składa się ona z dwóch odwiertów technologicznych do eksploatacji energii cieplnej przy użyciu pomp ciepła i dziewięciu otworów monitorujących, położonych w pobliżu tych dwóch odwiertów. Wszystkie odwierty wykonane na terenie obu poligonów badawczych wyposażone są w czujniki, które monitorują zmiany temperatury podczas ogrzewania (pobieranie energii cieplnej z ośrodka skalnego w zimie) i chłodzenia (przekazywania energii do górotworu w okresie letnim). Głównym celem badań jest sprawdzenie funkcjonalności i wydajności całego systemu. W artykule zaprezentowano niektóre aspekty zagadnień pozyskiwania energii cieplnej z górotworu oraz wyniki uzyskanych analiz wynikających z monitoringu i pomiarów zmian temperatury w warstwach powierzchniowych górotworu do głębokości około 20 m.VSB - Technical University of Ostrava has a unique possibility of studying temperature changes in the rock mass for long-term operation of heat pumps. The new Auditory building is not only the biggest object heated by a system of heat pumps in the Czech Republic but also in Central Europe. Along with a system of technological boreholes recuperating the heat of the rock mass there were also performed monitoring boreholes controlling temperature changes in the surrounding rock mass during when the heating system is active. The monitoring system is localized in the area of technological wells, the so called Big Research Range. VSB-TU has another such area called Small Research Range located near the Centre for Energy Investigations. It consists of two technological wells exploiting thermal energy with heat pumps and nine monitoring wells located nearby. All wells performed within both Research Ranges are equipped with sensors monitoring temperature changes during heating (taking energy from rock medium in winter) and cooling (accumulation of energy in the rock mass in summer). The main objective of the research is checking out the functionality and efficiency of the entire system. Some aspects of thermal energy production as well as the results of analyses from the monitoring and measurement of temperature changes in surface layers of the rock mass to about 20 m of depth have been presented in the paper
