An existing electronic system is to be further developed so that it can be used as the basis for agricultural process optimisation and documentation. With its help, process-relevant data is to be exchanged between the links in the process chain. This means that data is available to the individual process links for improved adjustment of the respective sub-processes and does not need to be recorded separately with additional sensors. At the same time, this data can also be used for documentation and monitoring purposes. Grain harvesting technology is being used as a demonstrator for this technology. However, the results will also be transferable to other agricultural products (maize, potatoes, beet, etc.).
