Abstract

A management system of a mining machine includes: a landmark that is placed at a mine and allows a non-contact sensor placed on the mining machine able to run at the mine to detect a relative position of the landmark and the mining machine; a storage device that registers a position of the landmark detected using the Global Positioning System; and a processing device that sets, upon the registration, a prohibited area where an entry of the mining machine is prohibited such that the position of the landmark is included in the prohibited area.

Claims

1. A management system of a mining machine comprising:

a landmark that is placed at a mine and allows a non-contact sensor placed on the mining machine able to run at the mine to detect a relative position of the landmark and the mining machine;

a storage device that registers a position of the landmark detected using the Global Positioning System; and

a processing device that sets, upon the registration, a prohibited area where an entry of the mining machine is prohibited such that the position of the landmark is included in the prohibited area.

2. The management system of a mining machine according to claim 1, further comprising an operating unit able to input an operation signal for registering the position of the landmark after the position of the landmark is detected using the Global Positioning System, wherein

the registration includes an operation of the operating unit.

3. The management system of a mining machine according to claim 1, further comprising a communication system that transmits an instruction signal to the mining machine to prevent the mining machine from entering the prohibited area.

4. The management system of a mining machine according to claim 1, further comprising a generation apparatus that generates a travel route on which the mining machine runs, wherein

the mining machine runs along the travel route on at least a part of a load site, a dump site, and a haul road leading to at least one of the load site and the dump site at the mine, and

the generation apparatus generates the travel route to prevent the mining machine from entering the prohibited area.

11. The management system of a mining machine according to claim 4, wherein the generation apparatus generates the travel route in a manner where the landmark is situated in a detection area of the non-contact sensor.

12. The management system of a mining machine according to claim 1, wherein whether the position of the landmark detected using the Global Positioning System is registered in the storage device is determined based on a detection state of the Global Positioning System.

13. The management system of a mining machine according to claim 1, wherein whether the position of the landmark detected using the Global Positioning System is registered in the storage device is determined based on a relationship between the position of the landmark registered in the storage device and the position of the landmark detected using the Global Positioning System.

5. A management system of a mining machine, including a central control apparatus placed in a control facility, the management system comprising:

a landmark that is placed at a mine and allows a non-contact sensor placed on the mining machine able to run at the mine to detect a relative position of the landmark and the mining machine;

a storage device that is provided in the central control apparatus and registers a position of the landmark detected using the Global Positioning System;

a processing device that is provided in the central control apparatus and sets, upon the registration, a prohibited area where an entry of the mining machine is prohibited such that the position of the landmark is included in the prohibited area;

a generation apparatus that is provided in the central control apparatus and generates a travel route on which the mining machine runs to avoid the prohibited area; and

a communication system that transmits to the mining machine information on the travel route generated by the generation apparatus,

wherein the mining machine runs at the mine in accordance with the information on the travel route transmitted from the central control apparatus by the communication system.

6. The management system of a mining machine according to claim 5, wherein the generation apparatus generates the travel route in a manner where the landmark is situated in a detection area of the non-contact sensor.

7. The management system of a mining machine according to claim 5, wherein whether the position of the landmark detected using the Global Positioning System is registered in the storage device is determined based on a detection state of the Global Positioning System.

8. The management system of a mining machine according to claim 5, wherein whether the position of the landmark detected using the Global Positioning System is registered in the storage device is determined based on a relationship between the position of the landmark registered in the storage device and the position of the landmark detected using the Global Positioning System.

9. A management method of a mining machine comprising:

detecting a position of a landmark placed at a mine using the Global Positioning System;

registering the detected position of the landmark in a storage device;

upon the registration, setting a prohibited area where an entry of the mining machine able to run at the mine is prohibited such that the position of the landmark is included in the prohibited area; and

allowing a non-contact sensor placed on the mining machine to detect the landmark and detecting a relative position of the mining machine running outside the prohibited area and the landmark.
