METHOD FOR DETERMINING THE CONTAMINATION STATE OF AT LEAST ONE SENSOR OF AN AGRICULTURAL SPREADING MACHINE

摘要

The invention relates to a method for determining the soiling state of at least one sensor (14a-14g, 16a-16g) of an agricultural spreader (10), with the following steps: recording of measured values (22a-22g) by several sensors (14a-14g, 16a- 16g) of an agricultural spreading machine (10), wherein the measured values (22a-22g) relate to the flight behavior of the thrown grit, determining a setpoint range (24a-24g) for each of the multiple sensors (14a-14g, 16a-16g) during a calibration process an evaluation device (20) when spreading grit on an agricultural area and monitoring of the measured values (22a-22g) recorded by the multiple sensors (14a-14g, 16a-16g) with regard to leaving the for the respective sensor (14a-14g, 16a -16g) determined setpoint range (24a-24g) to identify sensor contamination by the evaluation device (20).
