<p>A self-propelled agricultural harvesting machine (1) is provided with a single channel network (300) for serial communication of digital data messages between programmable microprocessors (215, 218) in a multi-master configuration. The messages are encoded according to an advanced serial communications protocol and are available to all microprocessors (215, 218). The network comprises an optical transmission network with an active starpoint (230) and plastic optical fibres (231), which link the nodes which lay physically far away from each other. An RS232 socket, which is linked to the network (300), enables loading of data and programs to the microprocessors (215, 218). Thus is obtained a reliable and flexible control system for the machine settings, which comprise on-road and off-road (harvesting) parameters. The ground speed of the machine (1) is controlled by an actuator (65/78) and a command means (75, 80) which are linked to the network (300). The introduction of a wide range of automatic control routines simplifies to a large extent the tasks of the operator during operation. <IMAGE></p> |
