System comprising construction machine, transport vehicle with loading space and image-recording device, and method for displaying an image stream during the loading or unloading of a transport vehicle
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.
1. A construction machine comprising:
a machine frame and a conveyor arranged to pivot at the machine frame;
an image-recording device aligned to provide a field of view comprising at least a loading space of a transport vehicle, and configured to generate image data;
a computer system configured to:
determine further data comprising:
first data determined at least from the image data, and
second data comprising one or more material properties of milling material loaded onto the transport vehicle and/or a location from which the milling material was milled; and
transmit the further data to a reception and display device arranged at or in the transport vehicle.
2. The construction machine of claim 1 , wherein the second data comprises material properties of the milling material at corresponding locations.
3. The construction machine of claim 2 , wherein the second data comprises material properties of the milling material at one or more different layers for each corresponding location.
4. The construction machine of claim 1 , wherein the second data is determined from a detected mass and/or volume of milling material loaded onto the transport vehicle.
5. The construction machine of claim 1 , wherein the second data is determined from one or more detected operating parameters of the milling machine.
6. The construction machine of claim 5 , wherein the one or more operating parameters comprise one or more of: a milling depth; a milling volume removed; an advance speed; a milling drum speed of revolution; a relation between advance speed and milling drum speed of revolution; a milling drum used; a torque/output emitted by a drive engine of the milling machine; and/or an amount of water fed during a milling process to cool milling tools of the milling drum.
7. The construction machine of claim 5 , wherein the second data comprises physical properties of the milling material determined from the one or more operating parameters and/or a type of milling drum and/or information received via a user interface.
8. The construction machine of claim 7 , wherein the physical properties of the milling material are determined from a relation between an advance rate of the milling machine and a milling drum speed of revolution.
9. The construction machine of claim 5 , wherein the second data comprises which layer of a ground pavement has been milled, wherein the layer of the ground pavement which has been milled is determined from a detected milling depth at a respective location of the ground pavement.
10. The construction machine of claim 1 , wherein the first data determined from the image data comprises 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.
11. The construction machine of claim 10 , wherein the computer system is configured to determine, as a function of the point of impingement of the material in the loading space and/or as a function of the 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.
12. The construction machine of claim 1 , wherein the image-recording device is aligned towards the conveyor.
13. The construction machine of claim 1 , wherein the image-recording device is arranged at the conveyor.
14. The construction machine 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.
15. The construction machine of claim 1 , wherein the computer system 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 a unique identifier associated with the transport vehicle.
16. The construction machine of claim 1 , wherein the computer system 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 an image stream according to the original position and/or alignment.
17. A method for coordinating between a construction machine and a transport vehicle during loading or unloading of the transport vehicle, the method comprising:
recording images with an image-recording device mounted at the construction machine and aligned, as a minimum, towards a loading space of the transport vehicle;
determining further data comprising:
first data determined at least from the image data, and
second data comprising one or more material properties of milling material loaded onto the transport vehicle and/or a location from which the milling material was milled; and
transmitting, receiving, and displaying the further data on a reception and display device arranged at or in the transport vehicle.
18. The method of claim 17 , wherein the second data comprises material properties of the milling material at one or more different layers for each of one or more corresponding locations.
19. The method of claim 17 , wherein the second data is determined from a detected mass and/or volume of milling material loaded onto the transport vehicle.
20. The method of claim 17 , wherein the second data is determined from one or more detected operating parameters of the milling machine.
