Cyberphysical Systems and Sensors for Smarter Applications
IoT-Bus – Fieldbus for the Internet of Things
The IoT-Bus is a fieldbus with IPv6 support with an integrated security concept. The IoT-Bus combines the advantages of native Internet-Protocol support with the benefits of a fieldbus in terms of range, reliability, robustness and low latency. The IoT-Bus is based on the standards IEEE 802.15.4 and 6LoWPAN and uses a twisted pair interface driven by RS-485 transceivers. To keep the compatibility with the 6LoWPAN header compression the IEEE Std. 802.15.4 protocol was adapted accordingly for wired communication. This conformity allows a fast package routing between the wired IoT-Bus and wireless based networks without extensive protocol conversion. It bridges the gap within the IoT communications portfolio and offers a simple wired solution to connect sensors and actuators with the IoT and thus enables IPv6 networking.

SWARCO ─ Environmental Monitoring
In cooperation with the SWARCO Group the Application Center for Wireless Sensor Technology of the Fraunhofer IIS develops solutions in environment monitoring. In cooperation with Pepperl+Fuchs the Application Center for Wireless Sensor Technology developed sensor system for monitoring of underfloor waste containers and transmitting the measurements wirelessly. Sensors can identify the fill level and blockages of underfloor containers via ultra-sonic distance measurement. The user can select a critical value (percentage or filling quantity). If the fill level is higher than the critical value the user will be alarmed.
- Comfortable, worldwide monitoring of fill levels via PC, tablet or smartphone app
- Process optimization, because the regular on-site checks are avoided and the underfloor containers have to be checked only if the fill level is higher than the critical value -> increase of the efficiency -> reduction of costs
An IoT application for the „Smart Washroom“ shows how information between real-life applications and the digital world work seamlessly together. On this occasion washroom hygiene products of the company CWS-boco International GmbH were equipped with sensor and wireless technology. These equipped products are the basic equipment of the washroom: dispensers for toilet paper, soap, and cotton towels. The current fill level of all three products will be transferred throughout the building to a gateway via energy-saving wireless technology (Bluetooth® 4.0 LE, Fraunhofer s-net®). The data saved on the gateway is then transmitted (via WLAN, GSM, UMTS, LTE, Ethernet) to a server. The server prepares the data in a user-friendly manner and makes it available to the user. The fill levels can be displayed in absolute numbers, as a percentage or graphically.
Cyber Security Training Lab
Training and development in the field of IT security is an issue of national interest, given that cyber attacks on critical infrastructures or industrial complexes can result in significant financial losses, the disruption of vital supply networks, or the breakdown of public order. The growing trend toward connectivity and digitalization only accentuates the threat. This collaborative approach enables the latest theoretical or practical research findings to be immediately incorporated into the training program. Trainees will work in modern laboratories equipped with simulation tools allowing real-world threat scenarios to be tested. The consortium consisting of Fraunhofer AISEC, Fraunhofer IIS, the University of Applied Sciences OTH Amberg-Weiden and the University of Applied Sciences Aalen are specialised in the fields Embedded Systems, Mobile Security, Internet of Things and Ethical Hacking.
Harvesting Energy Efficiently with BlueTEG
At embedded world we will, among others, demonstrate the Bluetooth Low Energy sensor BlueTEG with thermoelectric energy supply. BlueTEG measures sensor readings such as the ambient temperature or acceleration rates and transmits this data via Bluetooth to a smartphone or tablet PC. Integrated in a compact housing, BlueTEG uses the temperature difference between the warm or cold objects and the environment to produce electrical energy to supply the electronic systems. BlueTEG does not require a battery and can be used in all areas of structure monitoring, automation or wearable sensors systems. Especially in service areas, important environmental data such as temperature, air conditions, hazardous gases, etc. can be easily determined and transmitted via Bluetooth. The energy required for this is gained by our BlueTEG due to the temperature difference between heating or water pipes and ambient temperature. Lowest temperature differences are sufficient for smooth detection and transmission.
Flexible Battery Management for Complex Battery Systems
For the monitoring of larger battery storages, Fraunhofer IIS is showing the flexible battery management system FlexBMS at embedded world (Hall 4, booth 460). A small electronic module at each cell detects cell parameters such as voltage and temperature. Optimized bus communication between these electronic modules minimizes the need for wiring between the cells. The FlexBMS is also capable of precisely predicting the remaining capacity and the state-of-health by means of shunt- or resistance-based current measurements. This allows run time or range forecasts to be made, which eliminates the need for a safety buffer. The monitoring of any cell or module combination does not require any hardware adaptation. Furthermore, this flexible BMS can actively compensate for charge differences between the individual battery cells in order to always utilize the maximum capacity of the battery cells.
Efficient networks in vehicles for data rates up to 10 Gbit/s
In particular, high-resolution cameras and displays in vehicles are continually pushing data rates higher. With a new high-speed link, it is possible to transfer data rates of 10 Gbit/s in real time using a single copper cable. The physical layer is ideal for high-bit-rate data streaming used in driver assistance systems, for connecting mobile devices as well as for multimedia applications in vehicles. Consuming less than one watt for every transmitter/receiver pair, the new physical layer can transmit 10 Gbit/s over a single twisted pair cable 10-15 m long. Application areas include industrial facilities, mechanical and systems engineering, automation technology, medical technology, robotics and data centres. Broadcasting that uses multiple cameras and HD or even 4k video streaming can also benefit from the technology.
