The present disclosure relates to an electronic detonation device with a dual antenna for a blasting system and a blasting system using the same and, more particularly, to an electronic detonation device with a dual antenna for a blasting system and a blasting system using the same, wherein the electronic detonation device has a wireless communication module with an antenna positioned in each of an upper portion and a lower portion of the wireless communication module to secure stable communication reliability.
In general, explosives are used in engineering work, such as rock blasting for tunnel construction and building demolition. In particular, a plurality of holes, into which explosives are to be inserted, is drilled corresponding to the sections of a blasting target, i.e. the object to be blasted.
After an explosive is inserted into each of the drilled holes, the explosives are connected to a user terminal.
The explosives are exploded by operating the user terminal, thereby blasting the blasting target.
As a detonation device for explosives, a wireless-communication-type detonation device or a wired-communication-type detonation device may be used.
Conventionally, an electronic detonation device using wireless communication includes an electronic detonator, a wireless communication module, and wires connecting the wireless communication module to the electronic detonator.
The wireless communication module has an antenna therein for wireless communication provided to communicate with a user terminal.
After the electronic detonator is positioned to be inserted into the ground, the wireless communication module is placed on the ground. When an antenna-positioned surface of the wireless communication module is placed on the ground, radio waves may be disturbed by the ground, so it is difficult to stably perform wireless communication.
When the wireless communication module is placed and held on the ground, an antenna thereof is preferably positioned to face the sky to perform stable wireless communication for securing blasting accuracy. However, a wireless communication module of a current electronic detonation device has only one antenna positioned in an upper portion or a lower portion of a module housing, so it is difficult to hold the wireless communication module on the ground so that the antenna is positioned to face the sky.
Accordingly, the present disclosure has been made keeping in mind the above problems occurring in the prior art, and an objective of the present disclosure is to provide an electronic detonation device with a dual antenna for a blasting system and a blasting system using the same, wherein the electronic detonation device has a wireless communication module in which an antenna is positioned in each of an upper portion and a lower portion of a module housing, so that stable wireless communication is possible regardless of a placement direction of the wireless communication module on the ground.

Referring to
The electronic detonator 100 stores detonator information and is detonated in response to a blast command to explode an explosive.
The wire part 300 may be wound or folded several times and then stored using a wire band or a wire tie, and may be unfolded when in use.
The wire part 300 may be implemented as various shapes using known electric wires for communication, and a detailed description thereof will be omitted.
The wireless communication module 200 includes a communication module housing part 210 an antenna part positioned in the communication module housing part 210, and a wireless communication controller 240 controlling operation of the electronic detonator 100 by a signal transmitted from the antenna.
As an example, the communication module housing part 210 may have a donut shape in which a hollow part is positioned in the center thereof. The communication module housing part 210 may have a space to receive the wireless communication controller 240 controlling the operation of the electronic detonator 100 by a signal transmitted from the antenna, that is, the antenna part.
In more detail, the wireless communication module 200 may include: a first antenna part 220 positioned at an upper portion in the communication module housing part 210; a second antenna part 230 positioned to be spaced apart from a lower side of the first antenna part 220 in the communication module housing part 210; and the wireless communication controller 240 controlling the operation of the electronic detonator 100 by a signal transmitted from the first antenna part 220 or the second antenna part 230.
Furthermore, the wireless communication module 200 may include an antenna switch part 250 selectively connecting any one of the first antenna part 220 and the second antenna part 230 to the wireless communication controller 240.
The antenna switch part 250 selects an antenna with high signal strength among the first antenna part 220 and the second antenna part 230 and transmits a signal from the selected antenna to the wireless communication controller 240.
The first antenna part 220 is positioned to be in close contact with an upper surface of the communication module housing part 210, and the second antenna part 230 is positioned to be in close contact with a lower surface of the communication module housing part 210, thereby maximally securing the intervals and maximizing the distance between the second antenna part 230 and the upper surface of the communication module housing part 210, and maximizing the distance between the first antenna part 220 and the lower surface of the communication module housing part 210.
Accordingly, when the upper surface of the communication module housing part 210 is seated on the ground, the second antenna part 230 may be located to face the sky with the maximum distance from the ground. On the other hand, when the lower surface of the communication module housing part 210 is seated on the ground, the first antenna part 220 may be located to face the sky with the maximum distance from the ground.
Using a means such as an automatic signal recognition chip or a packet internet grouper (PING), the wireless communication controller 240 or the antenna switch part 250 may select an antenna with high signal strength among the first antenna part 220 and the second antenna part 230 and receive a signal from the selected antenna.
Regardless of whether or not the upper surface or the lower surface of the communication module housing part 210 is seated on the ground, the wireless communication module 200, any one of the first antenna part 220 and the second antenna part 230 may be positioned toward the sky at the upper portion of the wireless communication module 200 and may be stably communicated in wireless manner with a user terminal.
Meanwhile, a plurality of housing support protrusions 400, which is provided to separate the communication module housing part 210 from the ground, is positioned in each of the upper surface and the lower surface of the communication module housing part 210.
The plurality of housing support protrusions 400 protrudes from the upper surface of the communication module housing part 210 at intervals, and the plurality of housing support protrusions 400 protrudes from the lower surface of communication module housing part 210 at intervals.
When the upper surface of the communication module housing part 210 is seated on the ground, the housing support protrusions 400 separate the upper surface thereof from the ground, so that the first antenna part 220 at the upper portion may receive a signal with high signal strength.
When the lower surface of the communication module housing part 210 is seated on the ground, the housing support protrusions 400 separates the upper surface thereof from the ground, so that the strength of a signal transmitted to the second antenna part 230 positioned on the upper surface thereof may be increased.
The housing support protrusions 400 are positioned with an interval in which the electronic detonator 100 is fitted, so that the electronic detonator 100 is stored while being fitted in the interval.
The housing support protrusions 400 may be made of elastic materials, such as urethane, synthetic rubber, and silicone, so that the electronic detonator 100 may be stably fitted therein and may be stored with safer protection from external impact.
As the electronic detonator according to the present disclosure is held by the wireless communication module 200, storage and portability of the electronic detonator become easy, and thus convenience in use and storage may be secured.
Each of the housing support protrusions 400 is configured to have a height that is at least equal to or higher than a diameter or the maximum thickness of the electronic detonator 100, so that the electronic detonator 100 fitted between the housing support protrusions 400 may be positioned to be stably held without being in contact with the ground.
Meanwhile,
Referring to
The first supporting jig member 410 and the second supporting jig member 420 serve to separate the position of the communication module housing part 210 from the ground, and at the same time, the first supporting jig member 410 and the second supporting jig member 420 are moved in the facing directions to clamp the electronic detonator 100, so that the electronic detonator 100 may be held on each of the upper surface and the lower surface of the communication module housing part 210.
The first supporting jig member 410 and the second supporting jig member 420 have respective V-shaped groove parts on facing surfaces thereof, so that the electronic detonator 100 with a different diameter is stably held.
The first supporting jig member 410 and the second supporting jig member 420 have respective elastic pad members 450 on the facing surfaces thereof. Therefore, when the first supporting jig member 410 and the second supporting jig member 420 clamp and hold the electronic detonator 100, the electronic detonator 100 may be prevented from being damaged and may be stably clamped and held. In addition, when an impact occurs with the wireless communication module 200 while the electronic detonator 100 is held, the elastic pad members 450 absorb the impact so that the electronic detonator 100 may be stored in a safer state.
The housing support protrusions 400 are positioned as the pair facing each other, so that the rod-shaped electronic detonator 100 may be clamped in two places in a longitudinal direction to be stably held.
On each of the upper surface and the lower surface of the communication module housing part 210, a plurality of housing support protrusions 400 is arranged as a pair facing each other to be spaced apart from another pair of housing support protrusions 400 in a circumferential direction of the communication module housing part 210. Accordingly, the rod-shaped electronic detonator 100 may be supported in various directions, thereby increasing convenience in holding the electronic detonator 100.
Further, the housing support protrusions 400 may include a detonator position detecting sensor 440 detecting that the electronic detonator 100 is positioned between the first supporting jig member 410 and the second supporting jig member 420.
For example, the detonator position detecting sensor 440 is a laser distance sensor positioned on the same line as the jig moving part 430 between the first supporting jig member 410 and the second supporting jig member 420. When the electronic detonator 100 is positioned at a position equal to or less than a pre-set distance, the detonator position detecting sensor 440 may detect that the electronic detonator 100 may be positioned between the first supporting jig member 410 and the second supporting jig member 420.
In addition to the laser distance sensor, the detonator position detecting sensor 440 may be another known sensor, which detects that the electronic detonator 100 is positioned to be held between the first supporting jig member 410 and the second supporting jig member 420, between the first supporting jig member 410 and the second supporting jig member 420.
A pressure detecting sensor may be positioned in at least any one of the first supporting jig member 410 and the second supporting jig member 420 to detect pressure when the electronic detonator 100 is held between the first supporting jig member 410 and the second supporting jig member 420. When the pressure detecting sensor detects a pre-set pressure value, movements of the first supporting jig member 410 and the second supporting jig member 420 are stopped.
The jig moving part 430 may include an un-holding switch part. When an operator presses or manipulates the un-holding switch part, the first supporting jig member 410 and the second supporting jig member 420 may be moved in opposite directions to each other.
Although not shown in the drawings, the jig moving part 430 may include a jig moving screw that is screwed through each of the first supporting jig member 410 and the second supporting jig member 420 in opposite directions, and a screw rotation motor rotating the jig moving screws clockwise or counterclockwise.
For example, through the first supporting jig member 410, the moving screw may be screwed in a left-screw direction, and through the second supporting jig member 420, the moving screw may be screwed in a right-screw direction. The screwing directions may be reversed.
The first supporting jig member 410 and the second supporting jig member 420 are screwed in directions opposite to each other by the respective jig moving screws. Accordingly, according to rotation directions of the moving screws, when the interval between the first supporting jig member 410 and the second supporting jig member 420 is narrowed as the first supporting jig member 410 and the second supporting jig member 420 are moved in the facing directions, the electronic detonator 100 is held, or when the interval therebetween is widened as the first supporting jig member 410 and the second supporting jig member 420 are moved in the opposite directions, the electronic detonator 100 may be released from being held.
Each of the first supporting jig member 410 and the second supporting jig member 420 may have a traveling wheel member 460 that is rotatably positioned and protrudes downward.
When the wireless communication module 200 is placed on the ground or a floor, the traveling wheel member 460 is seated on the ground or the floor to allow the first supporting jig member 410 and the second supporting jig member 420 to be easily moved in the facing directions or the opposite direction.
When the operator positions the electronic detonator 100 at a location between the first supporting jig member 410 and the second supporting jig member 420, the detonator position detecting sensor 440 detects the positioning of the electronic detonator 100 and the jig moving part 430 moves the first supporting jig member 410 and the second supporting jig member 420 in the facing directions or opposite directions, so that the electronic detonator 100 is held between the first supporting jig member 410 and the second supporting jig member 420.
When the pressure required for holding the electronic detonator 100 is equal to or higher than the pre-set pressure value, movements of the first supporting jig member 410 and the second supporting jig member 420 are stopped so that the electronic detonator 100 may be prevented from an accident occurring when the electronic detonator 100 is compressed to a pressure equal to or higher than a pre-set pressure.
When the electronic detonator 100 held between the first supporting jig member 410 and the second supporting jig member 420, as the operator presses or manipulates the un-holding switch part, the first supporting jig member 410 and the second supporting jig member 420 releases the electronic detonator 100 while being moved in the opposite directions.
In summary, the first supporting jig member 410 and the second supporting jig member 420 are positioned to protrude toward each of the upper surface and the lower surface of the communication module housing part 210 so as to separate the position of the wireless communication module 200 from the ground. In addition, the first supporting jig member 410 and the second supporting jig member 420 may be moved in the facing directions to hold the rod-shaped electronic detonator 100.
The electronic detonator 100 may communicate with the user terminal 500 using wired communication or wireless communication to receive detonation time information or to transmit identifier information and positioning information to the user terminal 500.
Detonator information may include detonation time information, blast delay time information, identifier information, and positioning information.
The electronic detonator 100 may receive a blast command from the user terminal 500 to explode an explosive. When the electronic detonator 100 starts to count a blast delay time included in the blast command and the counting is completed, that is, after the blast delay time, the electronic detonator 100 detonates and explodes the explosive.
The wireless communication module 200 may allow the user terminal 500 and the electronic detonator 100 to communicate wirelessly with each other over a wireless network.
The wireless network may perform wireless communication by using known wireless networks, such as mobile radio communication networks including long-term evolution (LTE), Bluetooth™, Wi-Fi, wireless broadband internet (WiBro), and long range network (LoRa).
The user terminal 500 may synchronize with the electronic detonator 100 to transmit detonation time information to the electronic detonator 100 or to receive the identifier information and the positioning information from the electronic detonator 100.
