Abstract

The present disclosure relates to a blasting device for simultaneously registering multiple detonators based on blasting pattern information and a method of using the same, and the blasting device includes a blasting pattern information input unit that receives blasting pattern information about a blasting operation to be performed to store the received blasting pattern information, a key value sharing unit that shares a key value with a tracker possessed by an operator when the tracker is activated, a blasting area entry recognition unit that recognizes at least one communication module and tracker that are activated in a blasting area, and a detonator registration unit that registers multiple detonators by using the number of the at least one communication module and tracker recognized in the blasting area and pre-stored blasting pattern information.

First claim

The invention claimed is:

1. A blasting device for simultaneously registering multiple detonators based on blasting pattern information, the blasting device comprising:
a blasting pattern information input unit that receives blasting pattern information about a blasting operation to be performed to store the received blasting pattern information;
a key value sharing unit that shares a key value with a tracker possessed by an operator when the tracker is activated;
a blasting area entry recognition unit that recognizes at least one communication module and tracker that are activated in a blasting area; and
a detonator registration unit that registers multiple detonators by using a number of the at least one communication module and tracker recognized in the blasting area and pre-stored blasting pattern information,
wherein the key value sharing unit shares a key value for determining a blasting device in which each tracker is to be registered, when the tracker is to be registered with multiple blasting devices, and
wherein the detonator registration unit includes:
a third registration unit that, when two or more trackers and one communication module are recognized in the blasting area, pairs the communication module with a tracker located at a minimum distance from the communication module, the minimum distance being obtained by each tracker measuring a distance from the communication module using a received round trip time (RTT) and then registers the communication module in the blasting device registered through the key value that the tracker has, and registers a detonator corresponding to a blasting hole located at a minimum distance from a position of the tracker by comparing position pattern values included in position information about the tracker and the blasting pattern information stored in the blasting device; and
a fourth registration unit that, when two or more trackers and two or more communication modules are recognized in the blasting area, pairs a communication module and a tracker that are located at a minimum distance between each other, the minimum distance being obtained by each communication module and each tracker measuring a distance between each other using received round trip times (RTTs) and then registers the communication module in the blasting device registered through the key value that the tracker has, and registers a detonator corresponding to a blasting hole located at a minimum distance from a position of the tracker by comparing position pattern values included in position information about the tracker and the blasting pattern information stored in the blasting device.

2. The blasting device of claim 1 , wherein the detonator registration unit includes:
a first registration unit that, when one tracker and one communication module are recognized in the blasting area, registers the communication module in the blasting device registered through the key value that the tracker has, and registers a detonator corresponding to a blasting hole located at a minimum distance from a position of the tracker by comparing position pattern values included in position information about the tracker and the blasting pattern information stored in the blasting device; and
a second registration unit that, when one tracker and two or more communication modules are recognized in the blasting area, registers, in order, communication modules activated according to a deck charge number included in the blasting pattern information stored in the blasting device in the blasting device registered through the key value that the tracker has, and registers a detonator corresponding to a blasting hole located at a minimum distance from a position of the tracker by comparing position pattern values included in position information about the tracker and the blasting pattern information stored in the blasting device.

3. The blasting device of claim 1 , further comprising a detonator position output unit that, when a registered detonator is activated, outputs a coordinate map according to a blasting blueprint for the registered detonator and a coordinate map according to global positioning system (GPS) information for a current detonator to a display.

4. The blasting device of claim 1 , further comprising a detonator information check unit that outputs information about the registered detonator to a display by receiving the information about the registered detonator through the communication module when data loading is completed after the registered detonator is activated, to check and correct the information about the detonator through the display.

5. The blasting device of claim 1 , further comprising an arming command transmission unit that transmits an arming command when data loading is completed after the registered detonator is activated and check of information about the detonator is completed.

6. The blasting device of claim 1 , wherein the tracker receives a position correction value from a real time kinematic (RTK) positioning information system at preset time intervals, when the tracker is activated.

7. The blasting device of claim 1 , wherein the communication module switches to a sleep mode after providing information about the registered detonator to the blasting device.

8. A method of using a blasting device, the method comprising:
receiving, by a blasting pattern information input unit, blasting pattern information about a blasting operation to be performed to store the received blasting pattern information;
sharing, by a key value sharing unit, a key value with a tracker possessed by an operator when the tracker is activated;
recognizing, by a blasting area entry recognition unit, at least one communication module and tracker that are activated in a blasting area; and
registering, by a detonator registration unit, multiple detonators by using a number of the at least one communication module and tracker recognized in the blasting area and pre-stored blasting pattern information,
further comprising:
at the sharing a key value with a tracker possessed by an operator when the tracker is activated,
sharing a key value for determining a blasting device in which each tracker is to be registered, when the tracker is to be registered with multiple blasting devices,
wherein the registering of the multiple detonators by using the number of the at least one communication module and tracker recognized in the blasting area and the pre-stored blasting pattern information includes:
when two or more trackers and one communication module are recognized in the blasting area, paring the communication module with a tracker located at a minimum distance from the communication module, the minimum distance being obtained by each tracker measuring a distance from the communication module using a received round trip time (RTT) and then registering the communication module in the blasting device registered through the key value that the tracker has, and registering a detonator corresponding to a blasting hole located at a minimum distance from a position of the tracker by comparing position pattern values included in position information about the tracker and the blasting pattern information stored in the blasting device; and
when two or more trackers and two or more communication modules are recognized in the blasting area, paring a communication module and a tracker that are located at a minimum distance between each other, the minimum distance being obtained by each communication module and each tracker measuring a distance between each other using received round trip times (RTTs) and then registering the communication module in the blasting device registered through the key value that the tracker has, and registering a detonator corresponding to a blasting hol
