Experience your 5G uses case live!

With the new mobile radio communication standard 5G the high-performing requirements for IoT-application can be fullfilled. 5G enables latencies in milliseconds, data rates f upt to 20 GB/s, extremely high network coverage and precise positioning. Even before 5G is available everywhere - concrete use cases can be tested in the 5G Testbed at the Fraunhofer IISand the cons and pros for 5G in these applications can be evaluated.

5G-Testbed for AGVs and UAVs

The exact determination and transmission of the position data of goods and transport vehicles contributes to the further improvement of inter- and intralogistic processes. The positioning accuracy that can be achieved with 5G benefits from the integration of various localization technologies that are available in the 5G Bavaria Testbed Industry 4.0.

Edge Computing and Analytics in 5G

Real-time monitoring, analysis and control of processes can be implemented with 5G. Possible test scenarios are controlling robots in real time (Real-Time Closed-Loop Robotic Control), local real-time data analysis (Edge Analytics) or the safe and timely shutdown of machines in an emergency (Remote Emergency Stop).

Intelligent screw connection for safety-critical applications

Screw connections at critical, safety-relevant points on bridges, on structures that are load-bearing or exposed to high loads, and in production require the most complete control possible. With the intelligent screw connection, this is made possible by integrating it into wireless sensor systems: Using a special pressure and temperature thin-film sensor and a wireless, self-powered (via energy harvesting) sensor, the preload of the screw connection can be checked and sent via a standardized interface. Authentic, encrypted data can be transmitted via a cryptographically secured update process. The patented system was developed as a flexible toolkit with configurable individual components and is available as an Evalkit.

The Internet of Things or IoT is one of the key digital transformation technologies. In fact, it is not just one technology as many keep saying but a series of technological and other components that is really vast. The demand for highly productive, economical and flexible manufacturing processes is a high priority. The SmartTool.connect technology enables you to optimize your machining processes with the help of a proactive and intelligent tool holder. The integration of wireless components makes it possible to extract process data from close to the tool tip, transmit it in real time and evaluate it. In addition, the machining process can be purposeful guided and adaptively controlled. The integration of ultrasonic technology for vibration-assisted machining offers improved chip breaking and reduced burr formation. The age of the system does not matter, whether it is a new development or a retrofit, a large number of machines can be equipped with the universal tool holder.

Ultra-low latency Communication

Growing demands on the availability and efficiency of production plants lead to a greater need to continuously obtain information about their condition. This information is obtained through condition monitoring systems (CMS). Sensor-based monitoring of the current condition enables early detection of occurring damage and wear conditions, which is used to optimize maintenance programs. However, especially in industrial applications, the range of use cases and operating environments of the components to be monitored is very wide. An illustrative example are the widely used rolling bearings in drive technology. The smallest designs can be found in medical technology, while diameters of several meters are reached in wind turbines and cranes. Likewise, the loads, speeds and operating times to be accommodated vary from several hundred to several hundred thousand hours. Therefore, significant adaptations of the CMS become necessary for each individual case. First of all, this concerns the instrumentation with different types of sensors, for vibration, ultrasound, temperatures or measurement of impurities in lubricants. It turns out that different measurement variables are suitable for generating meaningful damage characteristics in each case. This results in adaptation work on the algorithms used for signal analysis, feature extraction and classification. Special potential lies in permanent instrumentation with heterogeneous, interconnected sensors in the sense of the IoT (Internet of Things) in conjunction with multivariate data analysis. In the SKALISENS project, a scalable sensor network is being developed and tested, which has the ability to integrate different sensors and their data streams, while being easily adaptable to different problems, e.g. by adding more sensors.
