Embedded Systems for Production 4.0

Positioning, Identification, Networks and Security

We are pleased to demonstrate our developments and solutions at embeddedworld 2014 hall 4 booth 140.

VEMPIRE® – embedded imaging platform

The embedded imaging platform Vempire® along with the in-house sensor frontend POLKA is designed for real time image data processing independently from a PC. The platform is remarkable for its high computing power and due to its compact design, it can be deployed wherever a PC cannot be used for reasons of space and energy or in case of high mobility usage. Core components are the high-performance FPGA and the multi-core DSP for real time image processing. The systems’ flexibility is demonstrated by a variety of interfaces, e.g. Gigabit Ethernet, GigEVision, HDMI as well as the modular sensor frontend, which allows the integration of different sensor frontends like Time-of-Flight, HD or HDR image sensors. Additional non-optical sensors, e.g. acceleration or temperature sensors complete the platform.

Multispectral sensors in CMOS

Fraunhofer IIS implements CMOS color sensors by design of optical nanostructures. The use of nanostructured metal layers enables the extension of the photo sensor´s functionality, like color and polarization sensibility. Further advantages are the high miniaturization, the possibility to apply many spectral channels on one chip and the temperature adaptability. The multispectral sensors are used e. g. for color regulation of LED lighting systems.

Energy Management Meets Electro Mobility

The Fraunhofer IIS displays an energy management framework (OGEMA 2.0), which enables the implementation of customer-specific energy management applications on embedded systems and its integration into a communications environment. OGEMA 2.0 can be applied in the field of electro mobility and for the communication off the building with the Smart Grid.

Energy-Harvesting

Energy harvesting uses the energy from the environment such as light, motion or heat in order to power small electronic devices. Energy-autonomous, maintenance-free and wireless systems with maximum runtime and unlimited standby become possible. In this way, powering sensors at remote locations becomes possible. Areas of application are, for example, sensor networks for monitoring of machines and plants (Condition Monitoring), tire pressure monitoring sensors or wireless light switches and sensors for building automation. Currently our engineers are working to use different sources of energy at the same time (vibration, light and heat) and to minimize the device and board space requirements.

Battery management system

The longer a battery does not require replacing the more costs can be saved. To increase the lifetime, an intelligent battery management system (BMS) is necessary to monitor each cell’s state and its charge condition. A special challenge is the active compensation of charge differences in the cells. The development of the Fraunhofer IIS can actively compensate the differences in charge. Due to its innovative BUS communication system and the temperature sensor integrated in the cell terminal the wiring was minimized, making it easy and inexpensive to assemble. In addition, the BMS-module is designed so flexibly that it may monitor any number of battery cells connected in series or parallel. The BMS is flexible in terms of number of cells and their connection and also in the wide variety of cell types it can monitor. This allows a special software for setting different parameters

Tools in manufacturing processes

Know how - know where - know what                             
Where is my tool? Is the tool used correctly? How to monitor in process manufacturing activities for quality assurance? These are questions that will be frequently raised in future manufacturing processes. With the combination of real-time position data and status classification, Fraunhofer IIS presents an innovative approach. The tool positioning technology does not require a special infrastructure and is extremely robust against interference from other sources.

RFID

RFID is currently the most important technology for identifying objects and people as well as optimizing production and other processes. In this context, LF, HF and UHF RFID tags embedded in glass-fiber- and carbon-fiber-reinforced plastic are becoming more and more widespread. This is made possible by technologies such as wireless power and data transmission (inductive RFID), fully integrated wireless sensors and miniaturized electronics.

Multibeam antenna

The multibeam antenna from Fraunhofer IIS is distinguished by its high reading rate and reliability compared with conventional antenna solutions. The larger field of view and the ability to synchronize the five active beams with the pallet position to the reading gate ensure maximum reading rates - with a low number of antennas. Applications can be found in logistics and trade.

BlackFIR®

In the context of the “Industry 4.0” initiative of the German Federal Ministry of Education and Research, the BlackFIR® platform provides a basis for transparent processes by enabling continuous real-time tracking of objects and people in enclosed areas. BlackFIR® is being used in production and supply chain management. Getting started is easy with the BlackFIR® 2.4 development kit. Simple to install, it can be tried out immediately and so is a quick, low-cost way of taking your first steps into real-time tracking.

s-net® technologies

Using s-net® Smart Applications professional users can easily compose applications for networked devices in a graphical user environment. The applications are created without directly programming the device firmware. The system applies a single set of rules to different application modules with the aid of a graphical development environment to generate intelligent application logic both on the node and within the network.
s-net® Smart Applications is currently available together with s-net® technology for energy-saving wireless multi-hop sensor networks. The application modules already included make it easy to control numerous hardware and software components, for instance sensors, actuators and algorithms.

Improved processor utilization by multi-threading

At embedded world 2014 exhibition Fraunhofer IIS presents the benefits of microprocessors with multi-threading.A real time comparison of Imagination MIPS microprocessors with single- and multi-threading in hardware running a HD video encoder application will be shown. By preventing wait states the processor utilization is improved. Either more computing power or less power dissipation can be achieved on the same silicon.

HallinOne® current measurement with differential magnetic field sensor technology


Sustainable management requires the knowledge of power consumption and the consequent reduction of energy demand. Fraunhofer IIS has developed a current sensor used in a clip-on ammeter, which can be installed very easily and permits current measurement without interrupting the production. This current sensor is presented at the embedded world 2014 exhibition in Nuremberg. It is based on the HallinOne® technology, which calculates the magnetic field generated by electric current using differential measurement. The measurement system is galvanically isolated and detects the energy values contactless.

3D magnetic field sensor in industrial joystick family

At the embeddedworld 2014 exhibition Fraunhofer IIS presents a joystick, which was developed in cooperation with DeltaTech. Due to the HallinOne® technology the sensor is prepared for the use under extreme conditions. HallinOne® stands for intelligent and robust sensor systems on one chip. This sensor technology operates by using contactless position and attitude measurement on magnetic basis with integrated 3D Hall sensors. Monaxial and polyaxial applications are implementable. The gradient based analysis leads to robustness against interfering fields. Temperature stability is reached by calculation of absolute angles. These special characteristics of the HallinOne® technology permit fulfillment of SIL requirements.
