Abstract

An arrangement for data recording and sampling for an agricultural machine includes a sensor set-up arrangement to detect properties contained in a material stream, means of taking a sample of the material from the material stream, and an electronic control unit. The control unit is configured to perform the following steps in response to a tripping signal: (a) instruct an actuator to bring the means into a position for sampling; (b) starting a recording of raw sensor arrangement data in a memory; (c) after depositing the sample at a desired sampling location, stop recording the raw data and instruct the actuator to return the means from the sampling position to an inactive position; and (d) store identification data to identify the sample together with the raw data in memory.

First claim

What is claimed is:

1. Arrangement for data recording and sampling for an agricultural machine in which a material stream is received, processed, stored or delivered during operation, the arrangement for data recording and sampling comprising:
a sensor arrangement for detecting properties of the material in the material flow, comprising a sensor interacting with the material and a processing device, which is configured to generate a signal with regard to one or more properties of the material on the basis of a raw data signals provided by the sensor;
a spout for dispensing a sample of the material from the material stream, which is actuatable by an actuator and arranged to place the sample at a desired deposition location; and
an electronic control unit connected to the sensor arrangement and the actuator in a signal-transferring manner;
wherein the control unit is configured to perform the following steps in response to a trigger signal:
(a) instruct the actuator to bring the spout into a position for sampling;
(b) starting a recording of the raw data in a memory;
(c) after the sample has been deposited at the deposition location, stop recording the raw data and instruct the actuator to return the spout from the sampling position to an inactive position; and
(d) save identification data to identify the sample together with the raw data in the memory.

2. The arrangement for data recording and sampling according to claim 1 , wherein the control unit is connected to a detection device which is set up to provide information with regard to a distance between the desired deposition location and a current storage location of the sample and/or to recognize that the sample is deposited at the desired deposition location.

3. The arrangement for data recording and sampling according to claim 2 , wherein the control unit is configured to begin the recording of the raw data only as soon as the detection device signals that the distance falls below a certain threshold value or the material flow is deposited at the desired deposition location.

4. The arrangement for data recording and sampling according to claim 3 , wherein the detection device is configured to determine on the basis of the position of the actuator the placement of the sample at the desired location.

5. The arrangement for data recording and sampling according to claim 4 , wherein the control unit is configured to control the actuator on the basis of the signals of the detection device.

6. The arrangement for data recording and sampling according to claim 5 , wherein the depositing location is one of on the ground or in a container attached to a transport vehicle for crops.

7. The arrangement for data recording and sampling according to claim 6 , wherein the agricultural machine is a forage harvester.

8. The arrangement for data recording and sampling according to claim 7 , wherein the detection device is configured to detect one of the crop flow emitted by the spout or the position of the spout.

9. The arrangement for data recording and sampling according to claim 8 , wherein the sensor arrangement comprises one of a near-infrared sensor or a sensor for the detection of whole or cracked kernels with a camera and an image processing system, and wherein the raw data is the recorded spectra or images of the near-infrared sensor or the camera.

10. The arrangement for data recording and sampling according to claim 9 , wherein the trigger signal can be generated by one of an operator via an operator interface or on the basis of the signals of the sensor arrangement.
