Workshop on sensor data management in September

16.08.2018

The »SensorThings API« standard of the Open Geospatial Consortium (OGC) stands for efficient management of sensor data in the Internet of Things. What's new about this open standard, what for and how is it used and how is it developing? Users, developers, experts and newbies will exchange ideas and share experience at the »OGC Summit on SensorThings API« on September 11, 2018 at the Hochschule für Technik in Stuttgart. The Fraunhofer Institute of Optronics, Systems Engineering and Image Exploitation IOSB in Karlsruhe will present its implementation of the API, »FROST – Fraunhofer Open Source SensorThings Server and Client«.

With a smartphone, for example, you can switch on the air conditioning in your home and a printer orders a new toner cartridge on its own – that's how the Internet of Things works. The most important basis for the Internet of Things is sensor data. With the help of sensors, information about »things« of any kind is collected and processed. These are used in many areas, for example in industrial environments, energy management, the environment or crisis management.

The SensorThings API (Application Programming Interface) is a standard that allows this data to be collected and processed in a uniform way despite the enormous variety of devices and fields of application. It builds on long OGC experience in the field of sensor data management and takes into account modern requirements for performant and easy to master interfaces. In the Summit the standard will be presented with its implementations and applications and further developments will be discussed.

Open source implementation for ease of use

Against the background of requirements from numerous applications in the megatrend topic of the Internet of Things, Fraunhofer IOSB has developed a server that implements the standard: »FROST – The Fraunhofer Open Source SensorThings API Server«. Great importance was attached to a functionally complete implementation with high performance. The aim was to enable easy use both in the research environment and in commercial applications in order to pave the way for innovations. Therefore, the implementation is provided as open source software.

The FROST Server has been certified by the Open Geospatial Consortium since August 2016 and is freely available under the GNU Lesser General Public License 3.0. This license allows commercial applications and ensures that further developments are made available to all users of the FROST Server.

Practical application in various projects

Numerous projects are using FROST. For example, Fraunhofer IOSB’s own building is equipped with a sensor network to collect building data such as temperature, energy consumption or water consumption values. Currently, the system stores about 6.8 million observations per month. These are combined with other operational data, for example to evaluate different approaches to room cooling in the summer months.

The European H2020 research project beAWARE, which is working on improving decision support in the event of extreme weather and climate events, also uses FROST. Heterogeneous data from different sources are integrated and stored. Environmental data is easily combined with data from social media, reports from first responders and from people in danger.

Scalability is an important feature of the FROST server for all projects. It runs on microcomputers, such as a Raspberry Pi, or in a cloud environment. Further information: www.iosb.fraunhofer.de/?FROST-Server.

Im Focus: First diode for magnetic fields

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.

Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...

Im Focus: Nonstop Tranport of Cargo in Nanomachines

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.

Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
