Abstract

A road finishing machine with a thermographic device releasably fixed to a portion of the machine for recording a georeferenced thermographic data record of at least one region of a pavement layer. The thermographic device includes a housing in which a detection unit for detecting a thermographic data record and a further detection unit for detecting a space-related data record for the thermographic data record are disposed.

First claim

What is claimed is:

1. A road finishing machine comprising:
a thermographic device releasably fixed to a portion of the road finishing machine for recording a georeferenced thermographic data record of at least one region of a pavement layer, the thermographic device comprising a housing, a detection unit disposed in the housing for detecting a thermographic data record, and an additional detection unit disposed in the housing for detecting a space-related data record for the thermographic data record, wherein the detection unit for detecting the thermographic data record comprises an infrared camera.

2. The road finishing machine according to claim 1 wherein the road finishing machine comprises a control platform with a roof, and the thermographic device is releasably fixed to the roof.

3. The road finishing machine according to claim 1 wherein the thermographic device comprises a fixing unit by which the thermographic device may be releasably fixed to the road finishing machine.

4. The road finishing machine according to claim 1 wherein the thermographic device further comprises an onboard computer arranged in the housing and designed to georeference the thermographic data record with the space-related data record.

5. The road finishing machine according to claim 4 wherein a LINUX operating system is installed in the onboard computer.

6. The road finishing machine according to claim 4 wherein the onboard computer comprises at least one interface via which the onboard computer may communicate with other units of the road finishing machine.

7. The road finishing machine according to claim 6 wherein the at least one interface is embodied for unidirectional or bidirectional data communication.

8. The road finishing machine according to claim 7 wherein the at least one interface comprises a CAN-BUS interface.

9. The road finishing machine according to claim 1 wherein the infrared camera is rigidly arranged in the housing.

10. The road finishing machine according to claim 1 wherein the thermographic device further comprises a blower in the housing for clearing precipitations from the detection unit for detecting the thermographic data record.

11. The road finishing machine according to claim 10 wherein the blower comprises a nozzle.

12. The road finishing machine according to claim 1 wherein the additional detection unit for detecting the space-related data record comprises a GNSS receiver.

13. The road finishing machine according to claim 1 wherein the housing of the thermographic device comprises a first housing shell and a second housing shell.

14. The road finishing machine according to claim 1 wherein the thermographic device further comprises a box in the housing, and the box is sealed in a watertight manner.

15. The road finishing machine according to claim 1 wherein the thermographic device further comprises another detection unit disposed in the housing for detecting a thermographic data record.

16. The road finishing machine according to claim 1 wherein a setting angle of the detection unit for detecting the thermographic data record may be adjusted depending on a screed paving width of the road finishing machine.

17. The road finishing machine according to claim 16 wherein the setting angle comprises a measuring range of the detection unit for detecting a thermographic data record.

18. The road finishing machine according to claim 1 wherein the thermographic device may be mounted to a chassis of the road finishing machine by means of a mounting, and wherein the thermographic device may be positioned by means of the mounting essentially at a level of a roof of the road finishing machine.
