DESCRIPTION:

BRIEF SUMMARY
The invention relates to an agricultural machine, in particular a combine harvester and thresher, which is comprised of component devices with associated microprocessors, of which at least one is a control station processor with a control keypad and a screen, which microprocessors are connected to measurement, actuation, and/or display members of the respective component devices and regarding this, process data which comes up in the component device in a controlling and/or regulating manner, or in a manner which displays it; these microprocessors are connected to one another by a communications bus via conventional interface circuits and via these circuits, in accordance with a protocol, continuously transmit actual operating data which is relevant for each other, such as rpm, speed, time, etc., together with an identifier, which is specific to the operating data.
Gottschalk discloses a device of this kind in his article "Trouble Shooting" in the periodical [Z:] Landtechnik 47, pp. 71-vol. 74, 1992. A plurality of microprocessors are connected to communicate by means of a standard CAN-communications bus and are connected to measuring and actuating members of component devices, namely an engine, running gear, work unit, and a display device, as well as to a diagnostic processor, and process their data for controlling and regulating the subdomain functions, and exchange it on a priority basis and employ it diagnostically.
It is provided that the individual component devices, as needed, are each consulted for actual operating data such as rpm, speed, time, etc. by another respective, relevant component device. The transmission of data is carried out in accordance with a standard protocol, by means of conventional interface circuits, which also furnish a single-lead emergency operation instead of the usual dual-lead operation. In complex agricultural machines, in particular combine harvester and threshers, this type of on-demand data polling from the other component devices requires an extensive expenditure for enciphering and deciphering, which can lead to extended queuing and long message processing times in the processors, and under some circumstances to inadmissible down times of the actuating and regulating devices and to malfunctioning of the same.
Furthermore, DE 37 08 324 A1 discloses a microprocessor-controlled information device of an agricultural machine, which shows wiring data and operating data, which are each specified and determined actually by measurement; the terms displayed are taken from a speech vocabulary memory, which is consulted each time. A specification or selection of operation adjustment data and parts of the operating program is carried out with dialogue support via a numeric keypad and different control keys or buttons. The perception of spoken information during continuous operation demands an increased concentration and attentiveness of the operator, which thus takes away from his observation of the machine and path of travel.
Furthermore, the Philips data sheet 82C200, Preliminary Functional Description, pp. 4-7, discloses a bus interface component, which includes an acceptance filter subassembly, with which the identifiers are compared one after the other, whereupon only the messages whose identifiers correspond to one of the ones stored in memory are transmitted to the affiliated microprocessor. The times for the successively carried out comparisons are relatively high depending on the identifier number, and messages which have arrived in the meantime under some circumstances are not received and are lost, unless a higher-priority software organization sees to it that additional monitoring and rerequesting of the transmission of the same message is carried out. This means further time delays, so that in practical applications of agricultural machine technology, real-time communication was possible only if no more than a very low number of message types was exchanged.
It is the object of the invention to increase the capacity of the agricultural machine mentioned at the begin
