Abstract

The present disclosure relates to 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, a further detection unit disposed in the housing for detecting a space-related data record for the thermographic data record, and a blower in the housing for clearing precipitation from the detection unit for detecting 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 for releasably fixing the thermographic device to the portion of 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 an interface via which the onboard computer may communicate with one or more other units of the road finishing machine.

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

8. The road finishing machine according to claim 7 wherein the interface is 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 blower comprises a nozzle.

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

12. The road finishing machine according to claim 1 wherein the housing of the thermographic device comprises first and second housing shells.

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

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

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

16. The road finishing machine according to claim 1 wherein the portion of the road finishing machine to which the thermographic device is releasably fixed comprises a chassis, and the thermographic device is releasably fixed to the chassis by a mounting such that the thermographic device may be positioned essentially at a level of a roof of the road finishing machine.

17. A road finishing machine comprising:
a control platform having a roof; and
a thermographic device releasably fastened to the roof of the control platform for recording a georeferenced thermographic data record of at least one region of a newly laid pavement layer, the thermographic device comprising a housing, a detection unit disposed in the housing for detecting a thermographic data record, a further detection unit disposed in the housing for detecting a space-related data record for the thermographic data record, and an onboard computer arranged in the housing and designed to georeference the thermographic data record with the space-related data record, and a blower in the housing for clearing precipitation from the detection unit for detecting the thermographic data record, wherein the detection unit for detecting the thermographic data record comprises an infrared camera.

18. A thermographic device for a road finishing machine for recording a georeferenced thermographic data record of at least one region of a newly laid pavement layer, wherein the road finishing machine includes a control platform having a roof, the thermographic device comprising:
a housing configured to be releasably fastened to the roof of the control platform of the road finishing machine;
a detection unit disposed in the housing for detecting a thermographic data record, the detection unit for detecting the thermographic data record comprising an infrared camera;
a further detection unit disposed in the housing for detecting a space-related data record for the thermographic data record;
an onboard computer arranged in the housing and designed to georeference the thermographic data record with the space-related data record; and
a blower in the housing for clearing precipitation from the detection unit for detecting the thermographic data record.
