Abstract
A sensor control assembly and method providing a secured sensor data and an optimized handling of the sensor including a sensor, a first processing unit adapted to provide a cryptographic checksum of sensor data, a distributed database, a second processing unit adapted to verify the sensor data, and a third processing unit adapted to determine the demand for calibration. A manufacturing device contains at least a part of the sensor control assembly.
Claims18
A sensor control assembly to securely verify and calibrate a sensor of a manufacturing device utilized in a manufacturing process of a product, comprising:
- a sensor of a manufacturing device,
- a first processing unit adapted to provide a cryptographic checksum of sensor data acquired by the sensor,
- a distributed database adapted to receive the sensor data, wherein the distributed database is protected against manipulation,
- a second processing unit adapted to verify the sensor data based on the cryptographic checksum,
- a third processing unit adapted to determine the demand for calibration or reset based on a comparison of sensor data acquired in a defined manufacturing condition and further sensor data acquired during the manufacturing process,
- wherein the second processing unit and third processing unit can be the same or different processing units.
