Abstract

The invention relates to a planning system and method for operating one or more road milling machines. In that context, material properties of a road are captured and are geographically associated with one or more roads or road segments. Based on the material properties, an expected milling output of a road milling machine is ascertained, in the context of carrying out milling tasks on the road, or an expected wear on the milling tools. An optimized sequence of milling tasks to be carried out is created on the basis of those data. Accordingly, the invention may enable optimized deployment of the one or more road milling machines and of resources necessary for carrying out the road milling tasks. Aspects of the planning system may be remotely implemented for centralized application with respect to each of the road milling machines, or locally implemented for individual road milling machines.

First claim

What is claimed is:

1. A method for operating one or more road milling machines, encompassing at least the following steps:
specifying at least two roads and/or road segments to be processed by milling;
ascertaining at least one expected milling output of each of the one or more road milling machines for the roads and/or road segments to be processed, based on at least one of material properties or characteristic values correlating with the material properties,
wherein the material properties and/or characteristic values are associated with at least one of road designations, designations of road segments, or geographic coordinates as respectively pertinent to the roads and/or road segments to be processed;
ascertaining and displaying a sequence, optimized at least with regard to the at least one expected milling output, of the roads and/or road segments to be processed by milling.

2. The method according to claim 1 , further comprising determining and displaying, on the basis of the material properties and/or characteristic values associated with the roads and/or road segments to be processed, one or more values selected from a group comprising:
a working time span;
an operating supplies consumption;
a quantity of required consumable parts;
a quantity of required operating supplies; and
a quantity of required operating auxiliaries.

3. The method according to claim 1 , wherein the sequence is further ascertained based on one or more values selected from a group comprising:
a working time span;
an operating supplies consumption;
a quantity of required consumable parts;
a quantity of required operating supplies; and
a quantity of required operating auxiliaries.

4. The method according to claim 1 , wherein the material properties for the roads and/or road segments are determined from the characteristic values.

5. The method according to claim 1 , wherein the material properties associated with the roads and/or road segments comprise one or more of: an abrasiveness; a hardness; a material type; a material composition; a temperature; and/or a layer structure of the road or road segment.

6. The method according to claim 1 , wherein at least one machine parameter of each of the one or more road milling machines which is obtained for processing of each of the roads and/or road segments is determined as at least one of the characteristic values correlating with the respective material properties.

7. The method according to claim 6 , wherein the at least one machine parameter comprises a milling depth and/or an advance of the road milling machine and/or a milling drum rotation speed of a milling drum of the road milling machine and/or a torque transferred to the milling drum and/or a drive power transferred to the milling drum or an operating supplies consumption.

8. The method according to claim 7 , wherein a wear that has occurred on at least one tool of the road milling machine in the context of milling a specific area is taken into consideration in determining the material properties from the at least one machine parameter.

9. The method according to claim 1 , further comprising capturing position data of the road milling machine and associating the captured position data with determined material properties and/or characteristic values.

10. The method according to claim 1 , wherein the material properties and/or the characteristic values correlating with the material properties are determined from a process of installing the road or road segment.

11. The method according to claim 1 , wherein measured data ascertained with a measurement system are determined as characteristic values correlating with the material properties.

12. The method according to claim 1 , wherein transport times of the road milling machine between the roads and/or road segments to be processed, and/or maintenance intervals of the road milling machine, are taken into consideration in the specification of the sequence.

13. The method according to claim 1 , wherein a milled area and/or a milled volume and/or a milled mass and/or a milled distance, referred in each case to a time unit, is determined as the at least one expected milling output.

14. A planning system for coordinating road milling tasks for one or more road milling machines, the planning system comprising:
a memory networked with input and output units associated with the one or more road milling machines; and
a non-transitory medium having a computer program product stored thereon, the program product executable by a computer to direct the performance of:
capturing and storing in the memory material properties of roads and/or road segments, and/or characteristic values correlating with the material properties, in association with one or more of respectively pertinent road designations, designations of road segments, or geographic coordinates;
specifying at least two roads and/or road segments to be processed by milling;
ascertaining at least one expected milling output of each of the one or more road milling machines for the roads and/or road segments to be processed, based on the material properties and/or characteristic values associated with the roads or road segments;
ascertaining and outputting a sequence of the roads and/or road segments to be processed by milling, optimized at least with regard to at least one of the at least one expected milling output or wear.

15. The planning system according to claim 14 , wherein the program product is further executable to determine and display, on the basis of the material properties and/or characteristic values associated with the roads and/or road segments to be processed, one or more values selected from a group comprising:
a working time span;
an operating supplies consumption;
a quantity of required consumable parts;
a quantity of required operating supplies; and
a quantity of required operating auxiliaries.

16. The planning system according to claim 14 , wherein the sequence is further ascertained based on one or more values selected from a group comprising:
a working time span;
an operating supplies consumption;
a quantity of required consumable parts;
a quantity of required operating supplies; and
a quantity of required operating auxiliaries.

17. The planning system according to claim 14 , wherein the determined material properties comprise one or more of: an abrasiveness; a hardness; a material type; a material composition; a temperature; and/or a layer structure of the road or road segment.

18. The planning system according to claim 14 , wherein at least one machine parameter of each of the one or more road milling machines which is obtained for processing of each of the roads and/or road segments is determined as at least one of the characteristic values correlating with the respective material properties.

19. The planning system according to claim 18 , wherein the at least one machine parameter comprises one or more of: a milling depth of the road milling machine; an advance of the road milling machine; a milling drum rotation speed of a milling drum of the road milling machine; a torque transferred to the milling drum; a drive power transferred to the milling drum; and/or an operating supplies consumption.

20. The planning system according to claim 19 , wherein a wear that has occurred on at least one tool of the road milling machine in the context of milling a specific area is taken into consideration in determining the material properties from the at least one machine parameter.
