Abstract

A management system includes an input device provided to a loading machine that performs, after a first loading work of loading a load onto a first haul machine positioned at a first loading position at a loading site of a mine is ended, a second loading work of loading a load onto a second haul machine that is already positioned, during the first loading work, at a second loading position different from the first loading position, and a processing device to which an operation signal generated by the input device is to be output, wherein the processing device specifies a start time of the second loading work based on the operation signal generated by the input device at a time when the first loading work is ended.

Claims

1. A management system comprising:

an input device provided to a loading machine that performs, after a first loading work of loading a load onto a first haul machine positioned at a first loading position at a loading site of a mine is ended, a second loading work of loading a load onto a second haul machine that is already positioned, during the first loading work, at a second loading position different from the first loading position; and

a processing device to which an operation signal generated by the input device is to be output,

wherein the processing device specifies a start time of the second loading work based on the operation signal generated by the input device at a time when the first loading work is ended.

2. The management system according to claim 1, wherein the processing device specifies an end time of the second loading work based on the operation signal generated by the input device at a time when the second loading work is ended.

3. The management system according to claim 2, wherein the operation signal generated by the input device at the time when the second loading work is ended includes an instruction signal for the second haul machine to leave the second loading position.

4. The management system according to claim 1, wherein the operation signal generated by the input device at the time when the first loading work is ended includes an instruction signal for the first haul machine to leave the first loading position.

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

a position detection device that detects position information of the second haul machine,

wherein the processing device calculates a wait time length from a time when the second haul machine arrives at the second loading position to a time when the second loading work is started, based on a detected result by the position detection device and the operation signal generated by the input device at the time when the first loading work is ended.

6. The management system according to claim 5,

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

wherein the processing device specifies a start time of an operation of the second haul machine travelling in a loaded state, based on the operation signal generated by the input device at the time when the second loading work is ended.

7. The management system according to claim 5, wherein the processing device specifies, based on position information of the second haul machine output from the position detection device, a start time and an end time of at least one of an operation of travelling of the second haul machine in an unloaded state, an 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, and an operation of having a load loaded by the loading machine at the loading position.

8. The management system according to claim 1, wherein the processing device calculates a time length required for a cyclic operation of the second haul machine moving between the loading site and a dumping site where a dumping work of a load is to be performed.

9. A management method comprising:

outputting, to a processing device, an operation signal generated by an input device provided to a loading machine that performs, after a first loading work of loading a load onto a first haul machine positioned at a first loading position at a loading site of a mine is ended, a second loading work of loading a load onto a second haul machine that is already positioned, during the first loading work, at a second loading position different from the first loading position; and

specifying a start time of the second loading work based on the operation signal generated by the input device at a time when the first loading work is ended.
