This paper reports the study to design and develop a system for controlling and displaying the status of electric energy usage in an office room by using web application. The study aimed to create innovation for saving the energy and enhancing the lifetime of electrical equipment. The system was designed to control electrical equipment via the website by receiving the value from the detector. According to the analytical results, the website showed the usage status of the office room, consisting of four sections: current detector status, temperature sensor, motion detector status, and LDR status. The operational status of all sections was analyzed. It showed the usage status online. The system could control three-phase electrical equipment through the website and the status was also shown on the control cabinet. The test results were evident that the system was able to be utilized to measure the energy consumption of the electrical equipment in the room. Furthermore, a three-phase air conditioning system showed the usage status of electrical equipment. The system was able to detect the motion, the temperature of the light and the system displayed the operational status on both the control cabinet and the website. The system allows multiple users to access and control the power through their smartphone. Designed by customizable GUI on website, the system is easy to install, control and monitor of electronic devices widely used in everyday life. It can store the data of electricity usage in the room for more than 365 days and the data can be exported as an excel file.

Artykuł przedstawia badania mające na celu zaprojektowanie i wykonanie systemu kontroli i wyświetlania stanu zużycia energii elektrycznej w pomieszczeniu biurowym za pomocą aplikacji webowej. Badanie miało na celu stworzenie innowacji oszczędzających energię i wydłużających żywotność sprzętu elektrycznego. System został zaprojektowany do sterowania urządzeniami elektrycznymi za pośrednictwem strony internetowej poprzez odbieranie wartości z detektora. Zgodnie z wynikami analitycznymi strona internetowa pokazywała stan użytkowania pomieszczenia biurowego,składającego się z czterech sekcji:obecny detektor, czujnik temperatury, stan czujki ruchu i stan LDR. Przeanalizowano stan eksploatacyjny wszystkich odcinków. Pokazywał stan użytkowania online. System mógł sterować trójfazowymi urządzeniami elektrycznymi za pośrednictwem strony internetowej, a stan był również pokazywany na szafie sterowniczej. Wyniki testów wykazały, że system może być wykorzystany do pomiaru zużycia energii przez sprzęt elektryczny w pomieszczeniu. Ponadto trójfazowy system klimatyzacji pokazywał stan użytkowania sprzętu elektrycznego. System był w stanie wykryć ruch, temperaturę światła, a system wyświetlał stan pracy zarówno na szafie sterowniczej, jak i na stronie internetowej. System pozwala wielu użytkownikom na dostęp i kontrolę zasilania za pomocą smartfona. Zaprojektowany przez konfigurowalny graficzny interfejs użytkownika na stronie internetowej, system jest łatwy w instalacji, kontroli i monitorowaniu urządzeń elektronicznych szeroko stosowanych w życiu codziennym. Może przechowywać dane o zużyciu energii elektrycznej w pomieszczeniu przez ponad 365 dni, a dane można wyeksportować jako plik Excela.

Recently, the reduction of fuels consumption is a global challenge, in particular for significant investments in the automotive sector, in order to optimize and control the parameters involved for the partial or total electrification of vehicles. Thereby, the energy management system remains the axis of progress for the development of fuel cell hybrid electric vehicles. The fuzzy controller has been widely adopted for energy monitoring, where the determination of its parameters is still challenging. In this work, this problem is investigated through a secondary development of a fuzzy energy monitoring system based on the Advisor platform and particle swarm optimization. The latter is used to determine, for different driving conditions, the best parameters that increase the fuel economy and reduce the battery energy use. As a result, five tuned fuzzy energy monitoring system models with five sets of parameters are obtained. Evaluation results confirm the effectiveness of this strategy, they also show slight differences between them in terms of fuel economy, battery state of charge variations, and overall system efficiency. However, the fuzzy energy monitoring system tuned under multiple conditions is the only one that can guarantee the minimum of the state of charge variations, no matter the driving conditions.

The structure and operating principles of a system for monitoring and controlling the operation of a thermal energy store have been presented in this study. As a novel feature of the presented solution, the device can be operated as a thermal energy store that relies on specific heat of fluids or phase transition heat when packages of phase change materials (PCM) are placed inside the device. Grates were used to arrange PCM packages in a manner that guarantees the flow of the heat transfer medium. The grates were equipped with temperature sensors to control thermal decomposition throughout the entire tank. The use of aerogel for thermal insulation was also a novel solution. Only a thin layer of aerogel was required to reduce heat loss across the tank wall. The structure and functionality of the modelled thermal energy store correspond to real-life conditions. The model can be used to test monitoring and control systems and to analyse the phenomena observed during the operation of similar devices. The operation of the thermal energy store can be regularly monitored and controlled on-line from any location in the world. The developed model supports the automatic import of operating parameters into a database for further analysis.
