Virtual Sensors

Objective

Sensor technology has become increasingly important (e.g., Industry 4.0, IoT). Large numbers of machines and products are equipped with sensors to constantly monitor their condition. Usually, the condition of an entire system is inferred through sensors only focusing on certain parts of the entire system by means of a multiplicity of methods and techniques. However, for small components as well as relatively inexpensive or immutable parts of a machine, asset or product, sometimes it is either technically not possible or uneconomical to embed sensors.

This project aims to explore a system-oriented concept of how to monitor individual components of a complex technical system without including additional sensor technology. By using already existing sensors from the environment combined with machine learning techniques, it seems to be possible to infer the condition of a system component, without actually observing it. In consequence, condition monitoring or additional services based on the component’s behavior can be developed without overcoming the challenges of sensor implementation.
