Method and device for controlling a materials handling and/or construction machine

1. A method for controlling a materials handling and/or construction machine comprising a crane and/or a cable excavator, the method comprising:

selecting different control functions on a screen of a controller with a touchscreen function, wherein the selecting comprises touching a control function symbol, and respective functional parameters of the selected control function are set;

displaying on the screen a working region boundary of a working region delimiting function for automatically deactivating and/or slowing down at least one actuator together with a display of the materials handling and/or construction machine and/or the work surroundings thereof in the form of a touchscreen display element when the working region boundary is reached and is adjusted by touching and moving the working region boundary on the screen relative to the display of the materials handling and/or construction machine and/or the work surroundings thereof;

providing a machine-readable code by an operating aid on the screen; and

scanning the machine-readable code by a mobile terminal, wherein the scanning causes the mobile terminal to call up additional information on the selected control function and to display the additional information on the mobile terminal.

2. The method of claim 1 , further comprising preconfiguring a contour of the working region boundary by touching one of a plurality of selection contours displayed on the screen.

3. The method of claim 1 , further comprising changing a contour of the working region boundary by tapping a contour point of the working region boundary and moving the tapped contour point by wiping along the screen.

4. The method of claim 1 , further comprising changing a contour of the working region boundary by adding an additional contour point, wherein the additional contour point is created by tapping a screen point spaced from the previously displayed working region boundary.

5. The method of claim 1 , further comprising moving and newly positioning the working region boundary relative to the materials handling and/or construction machine by touching on the screen and wiping along the screen.

6. The method of claim 1 , wherein a distinction is made between moving the working region boundary and changing the shape of the working region boundary by touching the screen differently, wherein touching the screen differently comprises tapping once or several times and/or by touching with one or more fingers.

7. The method of claim 1 , further comprising automatically displaying the machine-readable code on the screen of the controller upon input of an erroneous and/or unforeseen control command.

8. The method of claim 7 , further comprising displaying the machine-readable code upon touching an auxiliary and/or information symbol displayed on the screen in the form of a touch screen display element.

9. The method of claim 1 , further comprising displaying the machine-readable code upon touching an auxiliary and/or information symbol displayed on the screen in the form of a touch screen display element.

10. The method of claim 1 , further comprising:

generating a representation of the work surroundings of the materials handling and/or construction machine displayed on the screen on the basis of image data from a camera and/or digital data from a building information model (BIM); and

displaying an inputter for inputting control commands on the screen at least at times simultaneously with the representation of the machine surroundings and/or the work tool.

11. The method of claim 10 , further comprising generating a superimposed screen representation in a manner of a virtual reality image on the screen by a display controller, wherein the superimposed screen representation in the manner of a virtual reality image is assembled from a camera image of the machine surroundings and a virtual representation of the machine surroundings and/or a building part comprising the received image data of the camera and the received digital data from the building information model (BIM).

12. A device for controlling a construction and/or materials handling machine comprising a crane and/or cable excavator, the device comprising:

a controller which comprises a screen with a touch screen function, wherein different control functions are represented on the screen by control function symbols and are selectable by touching one of the control function symbols; and

selectors on the screen for setting functional parameters of a selected control function of the control functions;

wherein the controller comprises a working region boundary function adapted to display a working region boundary on the screen with a representation of the materials handling and/or construction machine and/or the work surroundings thereof in the form of a touch screen display element and to adjust the working region boundary on the screen relative to the materials handling and/or construction machine by touching and moving the working region boundary,

wherein an operating aid on the screen comprises a machine-readable code which, when scanned by a mobile terminal, causes the mobile terminal to call up additional information on the selected control function and display the additional information on the mobile terminal.

13. The device of claim 12 , wherein a working region boundary function of the controller is adapted to preconfigure a contour of the working region boundary by touching one of a plurality of selection contours displayed on the screen.

14. The device of claim 12 , wherein a working region boundary function of the controller is adapted to change a contour of the working region boundary by tapping a contour point of the working region boundary and moving the tapped contour point by wiping along the screen.

15. The device of claim 12 , wherein a working region boundary function of the controller is adapted to change a contour of the working region boundary by adding an additional contour point, wherein the additional contour point is generated by tapping a screen point spaced from the previously displayed working region boundary.

16. The device of claim 12 , wherein a working region boundary function of the controller is adapted to move and position the working region boundary a new relative to the materials handling and/or construction machine by touching on the screen and wiping along the screen.

17. The device of claim 12 , wherein a working region delimiting function of the controller is adapted to distinguish between moving the working region boundary and changing the shape of the working region boundary by touching the screen differently, wherein touch the screen differently comprises tapping once or several times and/or by touching with one or more fingers.

18. The device of claim 12 , wherein the machine-readable code comprises a QR code.

19. The device of claim 12 , wherein the operating aid is adapted to automatically display a machine-readable code upon input of an erroneous and/or unpredictable control command.

20. The device of claim 12 , wherein the operating aid is adapted to display the machine-readable code upon touching an auxiliary and/or information symbol displayed on the screen in the form of a touch screen display element.

21. The device of claim 17 , further comprising a display controller for generating a superimposed screen representation in the manner of a virtual reality image on the screen comprising a camera image of the machine surroundings and a virtual representation of the machine surroundings and/or a building part comprising the received image data from the camera and the received digital data from the building information model (BIM).

22. A materials handling and/or construction machine comprising a crane or a cable excavator, wherein the materials handing and/or construction machine comprises the device of claim 12 .
