The increasing number of networked devices and sensors, the "Internet of Things" (IoT), enables diverse and new applications. However, it also provides for a rapidly growing amount of data. Processing data at its point of origin (edge computing) helps to deal with it efficiently. Edge computing strengthens the functionality, sustainability, trustworthiness and cost-effectiveness of electronic applications through the use of artificial intelligence and networking. The goal of the OCTOPUS projects is to provide application-specific highly innovative electronics to unlock these benefits.

Goals and approach

In the ImaB-Edge joint project, materials research and testing facilities are developing a modularly configurable electronic system in cooperation with hardware and software developers, construction companies and infrastructure operators, which lays the foundation for on-site assessment of engineering structures. The system is used for permanent monitoring of the integrity of civil engineering structures. Sensors integrated into a structure continuously record measurement data, which is collected in a node and analyzed and evaluated using artificial intelligence. By simply integrating a mobile ultrasonic inspection system, nondestructive testing can be performed at critical locations as needed to significantly improve the information content. The condition of the structure is then transmitted to a control center or to service personnel.

Innovations and perspectives

On the one hand, potentially fatal accidents can be avoided, and on the other hand, it can be ensured that cost-intensive construction measures are only carried out when they are actually necessary. The project thus contributes to the safety of infrastructure and to its cost-saving maintenance.
