Abstract
A device for determining the position of a road roller relative to a road finisher has a transceiver on the road roller for transmitting transmit signals and for receiving receive signals from at least two reference points on the road finisher spaced apart from each other. An evaluation unit determines the position of the road roller relative to the road finisher from the run time between transmitting the transmit signals and receiving the receive signals from the reference points.
Claims16
A device for determining the position of a road roller relative to a road finisher, comprising:
- a transceiver mounted to the road roller for transmitting transmit signals and for receiving receive signals caused by the transmit signal from at least two reference points spaced apart from each other on the road finisher;
- an evaluation unit for determining the position of the road roller relative to the road finisher based on a run time between transmitting the transmit signal and receiving a first receive signal from the first reference point and a run time between transmitting the transmit signal and receiving a second receive signal from the second reference point;
- and
- a determiner for determining the number of times the road roller has passed over a section of the road surface deposited by the road finisher using the positions of the road roller determined over time.
A road roller comprising a device for determining the position of a road roller relative to a road finisher, comprising:
- a transceiver mounted to the road roller for transmitting transmit signals and for receiving receive signals caused by the transmit signal from at least two reference points spaced apart from each other on the road finisher;
- an evaluation unit for determining the position of the road roller relative to the road finisher based on a run time between transmitting the transmit signal and receiving a first receive signal from the first reference point and a run time between transmitting the transmit signal and receiving a second receive signal from the second reference point;
- and
- a determining unit for determining the number of times the road roller has passed over a section of the road surface deposited by the road finisher using the positions of the road roller determined over time.
A method for determining the position of a road roller relative to a road finisher, comprising:
- transmitting transmit signals from the road roller to at least two reference points mounted to the road finisher;
- receiving a first receive signal caused by the transmit signal from a first reference point on the road finisher;
- receiving a second receive signal caused by the transmit signal from a second reference point on the road finisher;
- determining, using a computer, the position of the road roller relative to the road finisher based on a run time between transmitting the transmit signal and receiving the first receive signal and a run time between transmitting the transmit signal and receiving the second receive signal;
- and
- determining the number of times the road roller has passed over a section of the road surface deposited by the road finisher using the positions of the road roller determined over time.
A method for constructing a road, comprising:
- depositing a road surface by a road finisher;
- and
- compacting the road surface by a road roller using a method for determining the position of a road roller relative to a road finisher, comprising:
- transmitting transmit signals from the road roller to at least two reference points mounted to the road finisher;
- receiving a first receive signal caused by the transmit signal from a first reference point on the road finisher;
- receiving a second receive signal caused by the transmit signal from a second reference point on the road finisher;
- determining the position of the road roller relative to the road finisher based on a run time between transmitting the transmit signal and receiving the first receive signal and a run time between transmitting the transmit signal and receiving the second receive signal;
- and
- determining the number of times the road roller has passed over a section of the road surface deposited by the road finisher using the positions of the road roller determined over time.
A non-transitory computer readable storage medium comprising program code for performing a method for determining the position of a road roller relative to a road finisher, comprising:
- transmitting transmit signals from the road roller to at least two reference points mounted to the road finisher;
- receiving a first receive signal caused by the transmit signal from a first reference point on the road finisher;
- receiving a second receive signal caused by the transmit signal from a second reference point on the road finisher;
- determining the position of the road roller relative to the road finisher based on a run time between transmitting the transmit signal and receiving the first receive signal and a run time between transmitting the transmit signal and receiving the second receive signal, when the computer program runs on a computer;
- and
- determining the number of times the road roller has passed over a section of the road surface deposited by the road finisher using the positions of the road roller determined over time.
