Abstract

In a system comprising construction machine, transport vehicle with loading space and image-recording device, wherein the image-recording device is arranged at the construction machine and aligned, as a minimum, also towards the loading space of the transport vehicle, it is specified for the following features to be achieved: that a reception and display device is arranged at or in the transport vehicle, wherein the data recorded by the image-recording device are transmitted to the reception and display device via a transmission device arranged at the construction machine.

First claim

The invention claimed is:

1. A system comprising:
a construction machine having a machine frame and a conveyor arranged to pivot at the machine frame, and an image-recording device aligned to provide a field of view comprising at least a loading space of a transport vehicle; and
a processor configured to identify the transport vehicle based on a unique identifier associated with the transport vehicle and within the field of view of the image-recording device;
wherein data recorded by the image-recording device are transmitted to a reception and display device arranged at or in the transport vehicle, via a transmission device arranged at the construction machine.

2. The system of claim 1 , wherein the unique identifier is determined by the processor from an image captured of a vehicle registration plate for the transport vehicle.

3. The system of claim 1 , wherein the recorded and transmitted data comprise image data.

4. The system of claim 3 , wherein the processor is configured to adjust whether and/or to what extent further image data is made available based on the unique identifier.

5. The system of claim 3 , wherein the processor is configured to adjust a quality of the image data based on the unique identifier.

6. The system of claim 1 , wherein the reception and display device comprises at least one portable computer having a programmed application associated with the unique identifier and configured to receive the data transmitted via the transmission device at least while the unique identifier is within the field of view of the image-recording device.

7. The system of claim 6 , wherein the programmed application is configured to display a reference image on a screen of the at least one portable computer and to generate a signal responsive to a specified deviation of an image stream associated with the received data from the reference image.

8. The system of claim 1 , wherein the image-recording device is aligned towards the conveyor.

9. The system of claim 1 , wherein the image-recording device is arranged at the conveyor.

10. The system of claim 1 , wherein the image-recording device comprises one or more of: a video camera with a wide-angle lens, an infrared camera, a stereoscopic camera, and a PMD camera.

11. The system of claim 1 , further comprising:
an evaluation unit configured to ascertain data relating to a milling material, and/or a location associated with the milling material, and/or operating parameters of the construction machine;
wherein the transmission device is configured to transmit the further data to the reception and display device.

12. The system of claim 11 , wherein the processor is further configured to determine whether to transmit the further data, and/or to adjust a scope of the further data transmitted, to the reception and display device based on the unique identifier.

13. The system of claim 11 , further comprising a first storage device arranged at the construction machine, wherein the reception and display device comprises a second storage device, and wherein at least the further data transmitted to the reception and display device is stored: in the first storage device in association with the unique identifier; and/or in the second storage device.

14. The system of claim 11 , wherein the evaluation unit is configured to evaluate the data of the image-recording device and determine one or more of: a filling level in the loading space; a distance between the construction machine and the transport vehicle; and a point of impingement of material in the loading space.

15. The system of claim 14 , wherein the evaluation unit is configured to determine, as a function of a point of impingement of the material in the loading space and/or as a function of a distance between the construction machine and the transport vehicle, a start or stop signal which is transmitted to the reception and display device via the transmission device.

16. The system of claim 1 , wherein the processor is configured to determine an original position and/or alignment of the image-recording device and, pursuant to a change in the position or alignment, to direct display of the image stream according to the original alignment.

17. A method of selectively transmitting data from a construction machine to a transport vehicle, wherein the construction machine has a machine frame, a conveyor arranged to pivot at the machine frame, and an image-recording device aligned to provide a field of view comprising at least a loading space of a transport vehicle, the method comprising:
identifying the transport vehicle based on a unique identifier associated with the transport vehicle and within the field of view of the image-recording device; and
transmitting data recorded by the image-recording device to a reception and display device arranged at or in the transport vehicle, via a transmission device arranged at the construction machine.

18. The method of claim 17 , wherein the unique identifier is determined from an image captured of a vehicle registration plate for the transport vehicle.

19. The method of claim 17 , further comprising:
ascertaining data relating to a milling material, and/or a location associated with the milling material, and/or operating parameters of the construction machine; and
deciding whether to transmit the further data to the reception and display device, and/or to adjust a scope of the further data transmitted to the reception and display device, based on the unique identifier.

20. The method of claim 19 , further comprising evaluating the data of the image-recording device and determine further data comprising one or more of: a filling level in the loading space; a distance between the construction machine and the transport vehicle; and a point of impingement of material in the loading space.
