Eckelmann (Germany) developed the Isobus computer taking into account the ISO 25119 standard for mobile applications. Isobus (ISO 11783) is a communication protocol for the agriculture industry based on the SAE J1939 higher-layer protocol for CAN. Beside Isobus, a CANopen interface is available as well.
THE DEVICE IS DEVELOPED FOR ATTAINMENT of the AgPL (agricultural performance levels) b and c. It is planned to provide prototypes of the computer by the beginning of 2013. The flexible hardware and software design should allow using the device e.g. in dosing applications for seeds, fertilizers and pesticides.
Beside two CAN ports, the computer includes the 400-MHz Freescale i.MX25 processor and up to four LIN interfaces. The multi-functional I/Os are configurable according to the agricultural requirements of a certain application. Embedded Linux and Microsoft Windows Embedded Compact 7 are the available operating systems. The device is programmable in C or C++ languages using different established development environments or the Codesys (v. 3) from 3S. The rugged aluminum housing of the device allows for IP67 or optionally for IP69K protection.
Eckelmann has more than 30 years of experience in the automation of agricultural machinery with. One of the foremost goals of company’s solutions is to provide tractor cabins with a uniform operating and control concept. Using Isobus as a communication standard and Codesys as a development environment, customers are capable of programming their applications themselves and remain independent of a specific hardware. The Isobus system connects all tractor accessories (e.g. sowing machinery, crop sprayers and fertilizer distributors), which may be controlled via a central operator terminal.
As an OEM partner, the company has developed a controller for a fertilizer distributor from Rauch. The right dosing makes for more productive and ecological agriculture. The open automation concept admits of the integration of e.g. navigation systems (GPS), which make data for precision farming available. Mobile automation also helps to increase the energy efficiency of agricultural machinery, for instance, by need-based traction control. A current trend is to replace power take-offs with electrical motors that drive the accessories. The manufacturer is a member of the Competence Center Isobus (CCI).
