Abstract
A position at which a transport machine is to unload materials at a work site is appropriately determined. The transport machine transports the materials at the work site. A sensor detects an accumulated body of the materials accumulated on the ground at the work site. A controller provides a command for an operation of the transport machine. The controller recognizes the accumulated body on the basis of a detection result of the sensor and determines a position at which the transport machine is to unload the materials at the work site on the basis of information regarding the accumulated body.
Claims10
1:
- A system comprising:
- a transport machine that transports materials at a work site;
- a sensor that detects an accumulated body of the materials accumulated on ground at the work site;
- and
- a controller that provides an instruction for an operation of the transport machine,
- wherein the controller recognizes the accumulated body on the basis of a detection result of the sensor and determines a position at which the transport machine is to unload the materials at the work site on the basis of information regarding the accumulated body.
3 more elements
2:
- The system according to claim 1,
- wherein the work machine working at the work site includes a work implement, and
- the controller determines the position at which the transport machine is to unload the materials on the basis of a dimension of the work implement as well.
3:
- The system according to claim 2,
- wherein the work implement includes a bucket at a distal end, and
- the dimension of the work implement includes a width of the bucket.
4:
- The system according to claim 3,
- wherein the work machine includes a travel body, and
- the controller regards, as the position at which the transport machine is to unload the materials, a section that is obtained by sectioning the accumulated body by a dimension of the width of the bucket and that includes a minimum amount of accumulated materials, in an orthogonal direction with respect to a direction in which the travel body travels toward the accumulated body when the work machine stacks the materials on the accumulated body.
5:
- The system according to claim 1,
- wherein a work machine working at the work site includes a travel body, and
- the controller provides an instruction for an operation of the transport machine to unload the materials in a direction intersecting a direction in which the travel body travels toward the accumulated body when the work machine stacks the materials on the accumulated body.
6:
- The system according to claim 5,
- wherein the work machine includes a work implement with a bucket provided at a distal end, and
- an amount of materials transported by the transport machine is larger than a capacity of the bucket.
7:
- The system according to claim 1, wherein the controller transmits the position at which the materials are to be unloaded to the transport machine.
8:
- A system comprising:
- a sensor that detects an accumulated body in which materials that are targets to be worked on by a work machine are accumulated on ground at a work site;
- and
- a controller,
- wherein the controller recognizes the accumulated body on the basis of a detection result of the sensor and obtains a position at which an amount of accumulated materials in the accumulated body is a minimum on the basis of information regarding the accumulated body.
2 more elements
9:
- A controller for a work machine which
- recognizes an accumulated body in which materials that are targets to be worked on by the work machine are accumulated on ground at a work site, and
- determines a position at which a transport machine transporting the materials is to unload the materials at the work site on the basis of information regarding the accumulated body.
10:
- A method of determining disposition of materials comprising:
- recognizing an accumulated body in which materials that are targets to be worked on by a work machine are accumulated on ground at a work site;
- and
- determining a position at which a transport machine transporting the materials is to unload the materials at the work site on the basis of information regarding the accumulated body.
