Abstract

In a method for determining an area milled by at least one construction machine or at least one mining machine with a milling drum (2) working a predetermined area in several milling trajectories by at least one machine (1), determining the length of the milling trajectories along which a milling operation has taken place by evaluating the continuous machine positions, adding up the previously milled partial areas taking into account the length of the milling trajectory and the installed width of the milling drum (2), wherein the partial area currently milled along the milling trajectory is checked, either continuously or subsequently, for overlapping or multiple overlapping with any previously milled partial areas, and any partial areas which overlap are deducted, as overlapping areas, from the added-up previously milled partial areas, the total added-up partial areas milled minus the total overlapping areas established give the milled area.

(a) milling a ground surface in a plurality of milling trajectories with the at least one construction machine;
(b) determining a length of each of the milling trajectories by determining a plurality of machine positions along each trajectory;
(c) determining a partial usage corresponding to each trajectory as a function of the length of each trajectory and the milling width of each trajectory; and
(d) determining a total usage by adding the partial usage for the plurality of milling trajectories and subtracting any overlapping usage where one trajectory overlaps another trajectory.

2. The method of claim 1 , wherein:
the usage is determined as a milled area;
step (c) includes determining a partial milled area corresponding to each trajectory as a function of the length of each trajectory and the milling width of each trajectory; and
step (d) includes determining a total milled area by adding the partial milled area for the plurality of milling trajectories and subtracting any overlapping milled area where one trajectory overlaps another trajectory.

3. The method of claim 2 , wherein:
step (b) includes determining the machine positions with regard to at least one reference point on the at least one construction machine.

4. The method of claim 2 , wherein:
step (b) includes determining the machine positions using at least one GNSS receiver.

5. The method of claim 4 , wherein:
step (b) further includes using reference positioning data from a stationary GNSS receiver or a data reference service to determine the machine positions.

6. The method of claim 4 , wherein:
in step (b), in the event of interference with reception of the at least one GNSS receiver, any missing or incorrect positioning data are computed or corrected based on a previous and further machine position on the milling trajectory.

7. The method of claim 4 , wherein:
in step (b), in the event of interference with reception of the at least one GNSS receiver, any missing or incorrect positioning data are computed or corrected based on recorded distance travelled and steering angle data of the at least one construction machine.

8. The method of claim 2 , wherein:
step (b) includes determining the machine positions using at least one land based positioning system.

9. The method of claim 2 , further comprising:
