Abstract

A telemetry device for state acquisition for an agricultural working train (with at least a drive machine and an attachment) has a transmission unit for receiving state values from the working train, a tele-unit for wireless transmission of teledata sets to a telemetry server and a processing unit for generating the teledata sets on the basis of the state values that are received. The received state values embody drive state values assigned to the drive machine and device state values assigned to the attachment. The processing unit groups the received drive state values with the received device state values based on predefined grouping instructions and the grouped state values to generate a teledata set according to generation instructions.

Claims

1. A telemetry device (1) for state acquisition for an agricultural working train (2) that comprises a drive machine (3) and an attachment (4), the telemetry device (1) comprising:

a transmission unit (5) for receiving state values from the working train (2);

a tele-unit (6) for wireless transmission of teledata sets to a telemetry server (7); and

a processing unit (8) for generating the teledata sets on the basis of the received state values;

wherein the received state values comprise drive state values assigned to the drive machine (3) and device state values assigned to the attachment (4);

wherein the processing unit (11) groups the received drive state values with the received device state values on the basis of predefined grouping instructions; and

, on the basis of the grouped state values, generated a teledata set according to generation instructions.

2. The telemetry device (1) according to claim 1, wherein the grouping instructions call for grouping the state values with one another that are related to one another in a predetermined manner based on time.

3. The telemetry device (1) according to claim 1, wherein a state variable is assigned to every device state value, wherein the telemetry device (1) comprises a memory unit (9) for storing the most recently received device state value, of each state variable, and wherein the grouping instructions call for grouping the multitude of the most recently received device state values for each state variable with one another.

4. The telemetry device (1) according to claim 1, wherein the state values comprise measured values that were measured at a working device, an area to be worked or both.

5. The telemetry device (1) according to claim 1, wherein the processing unit (8) triggers the generation of a teledata set and the storage thereof in a telememory (10) at a specified minimum frequency.

6. The telemetry device (1) according to claim 1, wherein the processing unit (1) receives a device definition after a start-up procedure and before receipt of a state value and wherein the device definition assigns a particular state variable to each device state value.

7. The telemetry device according to claim 6, wherein the device definition comprises a unique vehicle identifier.

8. The telemetry device (1) according to claim 6, wherein the device definition characterizes a state variable as a triggering variable, and wherein the processing unit (8) triggers the generation of a teledata set and stores the teledata set in the telememory (10) upon receipt of a state value, the assigned state variable of which is characterized as a triggering variable.

9. The telemetry device (1) according to claim 1, wherein the working train (2) comprises a second device (11) as the further attachment, wherein the received state values also include second-device state values, and wherein the processing unit (8) includes a received second-device state value in the grouping, in accordance with the grouping instructions.

10. The telemetry device (1) according to claim 1, wherein the transmission unit (5) receives state values from a plurality of physical channels (13) in order to receive drive state values from a plurality of physical channels (13).

11. The telemetry device (1) according to claim 10, wherein the plurality of physical channels (13) comprises an ISO bus (13a), a control device bus (13b) connected to the control electronics 12 and a motor bus (13c) connected to the motor, the drive train or both.

12. Device electronics (14) for an agricultural attachment (4) having a device control structure (16), which forms a logical interface and, a working set (16a) for actuation of the device electronics (14),

wherein the device electronics (14) communicate with a transmission unit (5) of a telemetry device (1) according to claim 1, and comprises a logging structure (28) that forms a separate logical interface for autonomous transmission of drive state values of the attachment (4) to the transmission unit (5).

13. An agricultural working train (2) comprising a drive machine (3), an attachment (4) and a telemetry device (1) according to claim 1, wherein the attachment (4) has device electronics (14) for communication with the transmission unit (5) that autonomously transmit device state values to the transmission unit (5) at a specified minimum frequency.

14. A method for state acquisition for an agricultural working train comprising a drive machine (3) and an attachment (4), the method comprising the steps of:

receiving state values;

generating teledata sets;

transmitting the teledata sets to a telemetry server;

wherein the received state values comprise drive state values assigned to the drive machine (3) and device state values assigned to the attachment (4); and

grouping the received drive state values with the received device values on the basis of preferably predefined grouping instructions;

wherein the teledata set is generated on the basis of the grouped state values according to generation instructions.

15. A computer program product comprising program code means embedded in a non-transitory computer-readable medium for implementing all the method steps according to claim 14 when the computer program code means is run in a computer.
