Sensor-Technik Wiedemann GmbH (STW) is to present its comprehensive competence as a supplier for electrical and electronic (E/E) components, modules and system modules with the “SymonE” system demonstrator. “SymonE”, thus making the interaction of data, signals and electricity the focus of this year’s trade fair stand by STW at the Agritechnica in Hanover.
A battery-operated test vehicle has been developed on the basis of a conventional commercial vehicle for STW and partner products, which allows the possibilities and added value facilitated through the integration of digitalization, automation and electrification to be experienced. Here aspects such as Industry 4.0 or the Internet of Things (IoT), semi-autonomous driving and working, and E-mobility are addressed.
As a result, “SymonE” is, amongst other things, intended for tests on electrified attachment devices which are supplied at the AEF power socket (front + rear) and therefore offer manufacturers brand-neutral access to an electric tractor. The demonstrator is also intended for the development of defined semi-automations and full-automations for the operator (Operator Assistance Systems, OPAs).
“SymonE” is completely electrified and equipped with an extremely compact 650V/90 kWh battery by Kreisel Electric, an 80 kW powerMELA E-machine by STW for the two-gear all-wheel drive and a second E-machine for braking and working hydraulics. Highly efficient control units, a high-performance VSX terminal by STW, four cameras and the on-board telecommunications module permit extensive support of the working process on-site and its integration into the process chain.
The supporting functions, such as the intelligent central electrics from the STW BCX family, and battery charging technology with CCS plugs, as well as further sensors such as those for pressure and temperature, are also indispensable.
The joint competence thus generated in electrical drive technology, intelligent control units and ergonomic operation, service-friendliness and cloud-based integration into operational logistics is to be demonstrated at the STW stand and is to be made experienceable for all visitors.
