The modern agricultural machinery most common use of the embedded electronic and remote sensing technology demands adoption of the Precision Agriculture (PA). One of the common devices is the Virtual Terminal (VT) for tractor. The VT’s functions and terminology are described in the ISO11783 standard. This work presents the control system design and implementation of the VT and some Electronic Control Units (ECU) for agricultural vehicles based on the ISO 11783 standard. The VT development of the hardware and software systems is implemented in the advanced embedded system and by using the IsoAgLib open library. The advanced embedded system is made by the Samsung S3C6410 ARM11 core microprocessor based embedded board with CAN module and working environment is Windows Embedded CE 6.0 (WinCE6.0). The IsoAglib library provides several open sources to implement ISO11783 protocols. It’s written by an object oriented C++ programming language. In this paper, we describe ISO11783 based tractor control system via Controller Area Network (CAN) and how to implement the embedded system. The paper also describes CAN-Bus device driver in WinCE6.0 and some modifications of IsoAglib for our target system. The target system consists of the VT, ECU of GPS and ECU of Sprayer for agricultural tractor. The ECU of GPS and ECU of light controller are implemented by using STM32F107F ARM Cortex-M3 based development boards.
