Abstract: A method for monitoring autonomous agricultural production machines is disclosed. The autonomous agricultural production machine autonomously performs an agricultural job. When an anomaly occurs, the autonomous agricultural production machine performs a response routine, interrupting the performance of the agricultural job. The autonomous agricultural production machine senses anomaly data during and/or after the response routine and transmits the anomaly data to a remote monitoring center in a reporting routine that a user may access in the remote monitoring center. The remote monitoring center generates, based on the anomaly data, a control instruction and transmits the control instruction to the autonomous agricultural production machine to execute in order to further respond to the anomaly and thereafter continue to perform the agricultural job.

Abstract: The functional condition of an induction crucible furnace is checked by first establishing a set-point parameter corresponding to an optimum functional condition of the induction crucible furnace and characterizing the vibratory behavior of same. Then, during normal operation of the furnace, an actual-value parameter of the vibratory behavior is determined. These two parameters are then compared and, if a magnitude of a difference therebetween exceeds a threshold, an alarm is generated.

Abstract: An agricultural distribution machine that includes a carrier vehicle with a distributor boom that is movable at least about a pivot axis is described. The machine also includes a controlling apparatus that generates a controlling force to move the distributor boom about the pivot axis.
