Abstract

A management system includes a position detection device, installed in a haul machine that travels at a mine, capable of detecting position information of the haul machine, and a processing device to which the position information of the haul machine detected by the position detection device is to be output, wherein the processing device specifies, based on the position information of the haul machine output from the position detection device, at least one of a start time and an end time of each of a plurality of operations of the haul machine.

Claims

1. A management system comprising:

a position detection device, installed in a haul machine that travels at a mine, capable of detecting position information of the haul machine; and

a processing device to which the position information of the haul machine detected by the position detection device is to be output,

wherein the processing device specifies, based on the position information of the haul machine output from the position detection device, at least one of a start time and an end time of each of a plurality of operations of the haul machine.

2. The management system according to claim 1, comprising:

a management facility including the processing device,

wherein the position information of each of a plurality of haul machines is output to the processing device, and

wherein the processing device outputs, to the haul machine, an assignment instruction for the haul machine at the mine based on the position information of each of the plurality of haul machines.

3. The management system according to claim 1,

wherein the haul machine travels at a loading site where a loading work of a load is to be performed and an dumping site where an unloading work of a load is to be performed, and on a haul road connecting the loading site and the dumping site, and

wherein the plurality of operations of the haul machine include at least one of a first operation of travelling in an unloaded state, a second operation of moving to a loading position at the loading site after a wait state at a wait position at an entrance of the loading site is released, a third operation of having a load loaded by a loading machine at the loading position, and a fourth operation of travelling in a loaded state.

4. The management system according to claim 3, comprising:

an input device installed in the loading machine,

wherein an operation signal generated by the input device includes an instruction signal for the haul machine to leave the loading position.

5. The management system according to claim 4, wherein at least one of an end time of the third operation and a start time of the fourth operation includes a time when the operation signal is generated by the input device.

6. The management system according to claim 3, wherein the processing device calculates a time length required for a cyclic operation of the haul machine moving between the loading site and the dumping site.

7. A management method comprising:

detecting, by a position detection device installed in a haul machine that travels at a mine, position information of the haul machine;

outputting the position information of the haul machine detected by the position detection device to a processing device; and

specifying, based on the position information of the haul machine output from the position detection device, at least one of a start time and an end time of each of a plurality of operations of the haul machine.
