Agricultural OEM Krone bets on Qt software library for development of their terminal / First prototype read in less than three months
585 horsepower, 15.6 litres engine displacement and an up to 9 metre wide cutterhead – forage harvesters are among the most powerful agricultural machines. It takes a lot more technology and know-how to drive such a vehicle than a car. The driver terminal of a forage harvester must process information from more than 30 components like motor, cutterhead, metal detector or grinder within tenths of a second. The terminal additionally provides a diagnosis system. The agricultural OEM Krone from Lower Saxony has built all these functions into the touch-screen terminal of its forage harvester Big X 480/580. The HMI software of the terminal was developed with the GUI and application library Qt.

You have just installed a fresh Linux system. The next step is to build Qt from sources. You install the required Linux packages, configure and build Qt. After an hour or so, your build fails because a package is missing. You must start over again … and again … Wouldn’t it be nice to have a single command that installs all the required Ubuntu packages and save all these needless iterations?

When my customers develop embedded systems, they face similar challenges:
Using examples from different industries, I’ll first elaborate on the challenges and then on how Qt can help us to solve these challenges. These challenges are typical for nearly every industry nowadays: automotive, agricultural, medical, manufacturing, home-appliance, home-automation – to name just a few.
