Abstract

The present disclosure relates to a blasting system, the blasting system including: a drilling device configured to form blasting holes on a blasting target on the basis of a blasting design map; a charging device configured to place explosives in the blasting holes; a worker terminal configured to generate position information indicating a position of the worker terminal; detonators each including a global positioning system (GPS) device, and configured to detonate the explosives by a blasting command; and a central control unit configured to transmit the blasting command to the detonators.

First claim

The invention claimed is:

1. A blasting system comprising:
a drilling device configured to form blasting holes on a blasting target on the basis of a blasting design map;
a charging device configured to place explosives in the blasting holes;
a worker terminal configured to generate position information indicating a position of the worker terminal;
detonators each including a global positioning system (GPS) device, and configured to detonate the explosives by a blasting command; and
a central control unit configured to transmit the blasting command to the detonators,
wherein the detonators are configured such that, when a detonator is driven by the worker, the detonator transmits a registration request including a detonator position to the central control unit, and
the central control unit comprises a detonator setting part configured to match the detonator position with the blasting design map, to identify the detonator transmitting the registration request, and to transmit setting data corresponding to the identified detonator to the identified detonator, and
the setting data includes setting information, an initialization time, and a delay time.

2. The blasting system of claim 1 , wherein the detonator setting part is configured to confirm a detonator closest to the detonator position in the blasting design map, and to identify the confirmed detonator as the detonator transmitting the registration request.

3. The blasting system of claim 2 , wherein the central control unit comprises:
a storage part configured to store the blasting design map;
a positioning part configured to confirm a position of the drilling device, a position of the charging device, and a position of the worker terminal;
a display part configured to display the blasting design map, the position of the drilling device, the position of the charging device, and the position of the worker terminal; and
a blasting controller configured to generate the blasting command.

4. The blasting system of claim 3 , wherein, when at least one of the drilling device, the charging device, and the worker terminal is positioned within a blasting radius, the blasting controller generates no blasting command.

5. The blasting system of claim 3 , wherein the central control unit further comprises:
a drilling controller generating a first alarm, when the drilling device reaches designed positions of the blasting holes,
wherein, while the blasting holes are formed by the drilling device, the drilling controller receives drilling data indicating a drilling state from the drilling device.

6. The blasting system of claim 5 , wherein the central control unit further comprises:
a charging controller generating a second alarm, when the charging device reaches the designed positions of the blasting holes,
wherein, while the explosives are placed into the blasting holes by the charging device, the charging controller receives charging data indicating a charging state from the charging device.

7. The blasting system of claim 6 , wherein the display part is configured to further display the drilling state and the charging state.

8. The blasting system of claim 1 , further comprising:
a monitoring device configured to capture in the air an image of a blasting field in which the blasting target is positioned.

9. An operating method for a blasting system, the operating method comprising:
creating a blasting design map including designed positions where blasting holes are to be formed on a blasting target;
arranging the blasting system on a blasting field where the blasting target is positioned, the blasting system including a central control unit, a drilling device, a charging device, and a worker terminal;
forming, by the drilling device, the blasting holes on the basis of the blasting design map;
placing explosives and detonators in the blasting holes by the charging device and then driving the detonators by a worker, each of the detonators including a GPS device;
matching a detonator position with the blasting design map, identifying a detonator transmitting a registration request, and transmitting setting data corresponding to the identified detonator to the identified detonator;
preparing for blasting; and
transmitting a blasting command to the detonator,
wherein the detonators are configured such that, when a detonator is driven by the worker, the detonator transmits the registration request including the detonator position to the central control unit, and
the setting data includes setting information, an initialization time, and a delay time.

10. The operating method of claim 9 , wherein the transmitting the setting data comprises:
receiving the registration request by the central control unit;
confirming, by the central control unit, a detonator closest to the detonator position in the blasting design map;
identifying, by the central control unit, the confirmed detonator as the detonator that transmits the registration request; and
transmitting, by the central control unit, setting data corresponding to the identified detonator to the identified detonator.

11. The operating method of claim 9 , wherein the preparing the blasting comprises:
confirming positions of the drilling device, the charging device, and the worker terminal;
determining whether or not at least one of the drilling device, the charging device, and the worker terminal is positioned within a blasting radius; and
completing the blasting preparation, when at least one of the drilling device, the charging device, and the worker terminal is not positioned within the blasting radius.
