Mobile automation for construction machinery, agricultural vehicles and municipal vehicles is going through a thrilling phase of development. This industrial sector is comparatively young and thus still receptive for concepts that point the way ahead. The following essay will outline the requirements of the market, present modern solutions and open up future prospects. No wonder CAN plays an important part in this.
These days, the cabin of a modern tractor almost resembles the cockpit of an airplane. This has not come by chance, because every machine that is connected, be it a plough or a seeder, has got its individual controller and follows its individual operating concept. Still, this is not the absolute solution yet. The market is in motion aiming to standardize and harmonize controller technology and operating functions in this area.
Designed for harsh environments
Because of the prevailing climatic conditions, it stands to reason that rigid standards are needed for a controller hardware required in this area. The permitted input voltage is 8 VDC to 32DC; the degree of protection is IP67, and the required operation temperature is -30 °C through +85 °C.
The demands on controller software are also manifold and very high.
