MyJEVIS – My Java Envidatec VISualization


In cooperation with the Envidatec GmbH the MyJEVis-System (Java Envidatec Visualization) was developed for collecting, visualizing and analyzing data of the energy consumption of shops or similar facilities. The MyJEVis-System is based on a Java-Applet as GUI, a database and measuring devices which are installed in different objects like gas stations or shops. The structure of the MyJEVis-System is shown below this paragraphs.
The MyJEVis-system works in the following way. The devices collect data about the power-consumption of the object and various temperature values. The data is transmitted to the database where it is stored. The GUI takes over the function to visualize the data. At the moment there are different functionalities available. The most important is the visualization of the data, where it is also possible to show different data-rows simultaneously. The other implemented functionalities include different benchmarking modes and functions for monitoring that are able to generate alarms for various events. The development of new functionalities for the My-JEVis-System is planned.

About Lampros Fotiadis

Lampros Fotiadis MEng, MBA, was born in 1980 in Greece. His passion for engineering led him to receive his Engineer’s degree (MEng equivalent) from the Electrical and Computer Engineering school of the Aristotle University (Greece) in 2004. During his studies, he specialised in Electronics and Computer Engineering. In his diploma thesis, he simulated and implemented a multi-zone fuzzy-logic heating system using a real-time reconfigurable System-on-Chip. Pursuing a holistic approach to solving engineering problems, he successfully earned an MBA degree from the University of Macedonia (Greece) in 2006 and his master thesis examined the relation between European environmental policies and the European Energy market. He worked as an expert IT and Physical security consultant for more than 10 years and his expertise include system design and requirement analysis, system integration and product management. His recent areas of interests are Data Science, Machine Learning, Autonomous Driving and Smart Grids. Since February 2017 he is working as project member at the Institute of Computer Technology in the Energy&IT Group, where he is especially contributing know-how as IT and physical security consultant in the areas of smart grids and industry 4.0.
