US 2023/0143733 A1 · CONSTRUCTION METHOD AND CONSTRUCTION SYSTEM

Abstract

In a construction method using an excavator that is controlled by manual operation, and an excavator that includes an automatic working-equipment control unit automatically controlling second working equipment on the basis of at least one of a current terrain and a designed terrain of a construction range in a construction site, and a tooth-edge position of the second working equipment, a progress rate that indicates a volume of soil having been excavated by the excavator to a target volume of soil to be excavated by the excavator in the construction range is calculated, and when the progress rate is equal to or larger than a threshold, the excavator stops construction of the construction range, and the excavator takes over the construction of the construction range, from the excavator.

Dependent claims

A construction method using:

a first work machine that is controlled by manual operation;
and
a second work machine that includes an automatic working-equipment control unit automatically controlling second working equipment based on at least one of a current terrain and a designed terrain of a construction range, and a tooth-edge position of the second working equipment, the construction method comprising:
calculating a progress rate in the construction range for the first work machine based on the current terrain and the designed terrain of the construction range for the first work machine;
and
when the progress rate is equal to or larger than a threshold, the first work machine stops construction of the construction range, and the second work machine takes over the construction of the construction range from the first work machine.

A construction system using:

a first work machine that is controlled by manual operation;
and
a second work machine that includes an automatic working-equipment control unit automatically controlling second working equipment based on at least one of a current terrain and a designed terrain of a construction range, and a tooth-edge position of the second working equipment, the construction system comprising:
a storage unit that stores the designed terrain of the construction range for the first work machine;
an acquisition unit that acquires construction result data indicating a result of construction of the construction range for the first work machine;
a progress rate calculation unit that calculates a progress rate of construction by the first work machine, based on the designed terrain of the construction range for the first work machine stored in the storage unit and the construction result data acquired by the acquisition unit;
and
an instruction unit that instructs the first work machine to stop construction of the construction range and that instructs the second work machine to take over the construction of the construction range, when the progress rate calculated by the progress rate calculation unit is equal to or larger than a threshold.
