Abstract
A controller may obtain compaction data indicating one or more of a vibration amplitude or a vibration frequency used for a compaction drum of the compactor machine at a plurality of locations of the compactor machine on a paving material mat. The controller may determine, based at least in part on the compaction data, compaction energies produced by the compactor machine at the plurality of locations on the paving material mat. The controller may cause the compactor machine to perform a compacting operation at an area of the paving material mat based on the compaction energies.
Claims19
A compactor machine, comprising:
- a compaction drum comprising a vibratory component configured to vibrate the compaction drum;
- and
- a controller, comprising one or more processors, configured to:
- detect, using a vibration sensor, compaction data indicating a vibration amplitude and a vibration frequency used for the compaction drum at a location of the compactor machine on a paving material mat;
- determine, based at least in part on the compaction data, a local weight of the compactor machine at the compaction drum, and an amount of time spent by the compactor machine at the location, a compaction energy produced by the compactor machine at the location of the compactor machine on the paving material mat;
- generate, based on the compaction energy, a compaction map indicating degrees of compaction at least at the location of the compactor machine on the paving material mat;
- cause, in accordance with the compaction map, an adjustment to at least one of the vibration amplitude, the vibration frequency, or a travel speed of the compactor machine,
- wherein an amount of the adjustment is based on an amount by which a degree of compaction at the location differs from a target degree of compaction;
- and
- cause, in accordance with the compaction map, the compactor machine to return to the location to perform a compacting operation using the adjustment.
7 more elements
A controller of a compactor machine, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- obtain location data indicating a location of the compactor machine on a paving material mat;
- obtain compaction data indicating one or more of a vibration amplitude or a vibration frequency used for a compaction drum of the compactor machine at the location of the compactor machine on the paving material mat;
- determine, based at least in part on the compaction data, a local weight of the compactor machine at the compaction drum, and an amount of time spent by the compactor machine at the location, a compaction energy produced by the compactor machine at the location of the compactor machine on the paving material mat,
- wherein the compaction energy indicates a degree of compaction at the location;
- cause, in accordance with the degree of compaction, an adjustment to at least one of the vibration amplitude, the vibration frequency, or a travel speed of the compactor machine,
- wherein an amount of the adjustment is based on an amount by which the degree of compaction differs from a target degree of compaction;
- and
- cause the compactor machine to return to the location to perform a compacting operation using the adjustment.

- wherein the compaction energies indicate respective degrees of compaction at the plurality of locations;
- causing, by the controller and in accordance with a degree of compaction at a location, an adjustment to at least one of the vibration amplitude or the vibration frequency,
- wherein an amount of the adjustment is based on an amount by which the degree of compaction differs from a target degree of compaction;
- and
- causing, by the controller, the compactor machine to return to the location to perform a compacting operation using the adjustment.
