The translated meaning of the German acronym 'LaSeKo' stands for 'Agricultural Ad-hoc Communication System for the Surveillance, Optimization and Documentation of harvesting processes'. The project is the succession of the ESOB project. The basic idea of that previous project was to develop and evaluate a system to control position and condition of mobile working machines, containers and accessory equipment in the construction industry. Due to a regulation of the European Union, the product liability law for food, the development of a documentation system for the entire harvesting process is obligatory. Based on the mobile electronic system developed in the ESOB project, the LaSeKo consortium is developing a technical approach to connect independent network devices and machines for the collection of process data, control and diagnostic purposes. The main item of the system is a private area network (PAN) module controlled by a microcontroller. On the basis of IEEE 802.15.4 wireless standard, the system is able to autonomously establish a network. The communication units (LaSeKo-Boxes) act independently. They comprise different interfaces e.g. two CAN interfaces, a GPS receiver and, if required, an additionally fitted GPRS port for data transfer via Internet. All combines and tractors of a harvesting fleet will be equipped with a communication unit (LaSeKo-Box). In addition to the technical details of the LaSeKo-Box, this paper focuses on possible applications in the field of machine diagnostics. The wireless data transfer can be used for a universal agricultural documentation system. Site specific harvest data as well as further crop data can be transmitted from the LaSeKo-Box of the combine harvester to the LaSeKo-Box of the transport vehicle simultaneously to transferring the crop. Thus, the transport vehicle transfers all information about the crop, e.g. its geographical growth position, the harvest quality, the harvesting time etc. This data can afterwards be transferred to the following crop processing stages, setting up a complete information chain, ending with the consumer as final destination. However, drawbacks might be the size of the considered crop batches and the potential mixing of different packages in the crop elevator, impeding clear retracement.
