Blasting system and operating method thereof

1. A method of operating a blasting system, the method comprising:

synchronizing a blasting device with a detonator;

setting a unit group including a plurality of the detonators;

setting a first detonator among the plurality of detonators of the unit group;

setting a wireless network generated from the first detonator; and

performing, by the blasting device, communications with the plurality of detonators of the unit group via the first detonator,

wherein the setting of the first detonator sets a detonator among the plurality of detonators of the unit group, located in a center, as the first detonator,

wherein the blasting device transmits a blasting command including delay times to the first detonator, and the first detonator transmits the blasting command including the delay times to the plurality of detonators of the unit group,

wherein the setting of the wireless network comprises:

setting the wireless network by connecting the first detonator to detonators among the plurality of detonators, located adjacently to the first detonator;

generating connection values for the plurality of detonators through the wireless network;

comparing the connection values and reference values for the plurality of detonators; and

when the connection value for a single detonator among the plurality of detonators is greater than the reference value for the single detonator among the plurality of detonators, resetting the wireless network, and

wherein the connection value for the single detonator is a number of the detonators among the plurality of detonators connected to the single detonator.

2. The method according to claim 1 , wherein the synchronization synchronizes an absolute time of the blasting device and an absolute time of each detonator among the plurality of detonators.

3. The method according to claim 1 , wherein the reference values are predetermined values in accordance with performance of the plurality of detonators.

4. The method according to claim 3 , wherein the blasting device stores the reference values in a blasting memory of the blasting device.

5. A blasting system comprising:

a detonator disposed in a blasting hole of a blasting target; and

a blasting device transmitting a blasting command to the detonator via a wireless network,

wherein the blasting device includes:

a synchronization module performing synchronization with the detonator;

a unit group setting module setting a unit group including a plurality of the detonators;

a first detonator setting module setting a first detonator among the plurality of detonators of the unit group; and

a network setting module setting the wireless network generated from the first detonator,

wherein the first detonator is located in a center of the plurality of detonators of the unit group,

wherein the blasting device communicates with the plurality of detonators of the unit group via the first detonator,

wherein the blasting device transmits the blasting command including delay times to the first detonator, and the first detonator transmits the blasting command including the delay times to the plurality of detonators of the unit group,

wherein the network setting module

sets the wireless network by connecting the first detonator to detonators among the plurality of detonators, located adjacently to the first detonator,

generates connection values for the plurality of detonators through the wireless network;

compares the connection values and reference values for the plurality of detonators; and

when the connection value for a single detonator among the plurality of detonators is greater than the reference value for the single detonator among the plurality of detonators, resets the wireless network, and

wherein the connection value for the single detonator is a number of the detonators among the plurality of detonators connected to the single detonator.

6. The blasting system according to claim 5 , wherein the blasting device includes a blasting communication part performing communications with the plurality of detonators of the unit group via the first detonator.

7. The blasting system according to claim 6 , wherein the synchronization module synchronizes an absolute time of the blasting device and an absolute time of each detonator among the plurality of detonators.

8. The blasting system according to claim 5 , wherein the reference values are predetermined values in accordance with performance of the plurality of detonators.

9. The blasting system according to claim 8 , wherein the blasting device stores the reference values in a blasting memory of the blasting device.
