Description

ELECTRONIC DETONATION DEVICE WITH DUAL ANTENNA FOR BLASTING SYSTEM AND BLASTING SYSTEM USING SAME TECHNICAL FIELD
[0001] 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.
BACKGROUND ART
[0002] Each document, reference, patent application or patent cited in this text is expressly incorporated herein in their entirety by reference, which means that it should be read and considered by the reader as part of this text. That the document, reference, patent application or patent cited in this text is not repeated in this text is merely for reasons of conciseness.
[0003] The following discussion of the background to the invention is intended to facilitate an understanding of the present invention only. It should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was published, known or part of the common general knowledge of the person skilled in the art in any jurisdiction as at the priority date of the invention.
[0004] 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.
[0005] After an explosive is inserted into each of the drilled holes, the explosives are connected to a user terminal.
[0006] The explosives are exploded by operating the user terminal, thereby blasting the blasting target.
[0007] As a detonation device for explosives, a wireless-communication-type detonation device or a wired-communication-type detonation device may be used.
[0008] 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.
[0009] The wireless communication module has an antenna therein for wireless communication provided to communicate with a user terminal.
[0010] 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.
[0011] 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.

BEST MODE
[0065] Hereinafter, the present disclosure will be described in detail.
[0066] Exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings as follows. Prior to the detailed description of the present disclosure, all terms or words used in the description and claims should not be interpreted as being limited merely to common and dictionary meanings. Meanwhile, the embodiments described in the specification and the configurations illustrated in the drawings are merely examples, and do not exhaustively present the technical spirit of the present disclosure. Accordingly, it should be appreciated that there may be various equivalents and modifications that can replace the embodiments and the configurations at the time at which the present application is filed.
[0067] FIG. 1 is a perspective view showing an embodiment of an electronic detonation device with a dual antenna for a blasting system according to the present disclosure. FIG. 2 is a view schematically showing a first embodiment of a wireless communication module of the electronic detonation device with the dual antenna for a blasting system and a blasting system using the electronic detonation device according to the present disclosure.
[0068] Referring to FIGS. 1 and 2, the electronic detonation device with the dual antenna for a blasting system according to the first embodiment includes an electronic detonator 100, a wireless communication module 200, and a wire part 300 connecting the electronic detonator 100 to the wireless communication module 200.
[0069] The electronic detonator 100 stores detonator information and is detonated in response to a blast command to explode an explosive.
[0070] 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.
[0071] The wire part 300 may be implemented as various shapes using known electric wires for communication, and a detailed description thereof will be omitted.
[0072] 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.
[0073] As an example, the communication module housing part 210 may have a donut shape in which a hollow part is positioned in the centre 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.
[0074] 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.
[0075] 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.
[0076] The antenna switch part 250 selects an antenna with high signal strength amongst 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.
[0077] 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 maximising the distance between the second antenna part 230 and the upper surface of the communication module housing part 210, and maximising the distance between the first antenna part 220 and the lower surface of the communication module housing part 210.
[0078] 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.
[0079] Using a means such as an automatic signal recognition chip or a packet intemet grouper (PING), the wireless communication controller 240 or the antenna switch part 250 may select an antenna with high signal strength amongst the first antenna part 220 and the second antenna part 230 and receive a signal from the selected antenna.
[0080] 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.
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] 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 whilst being fitted in the interval.
[0086] 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.
[0087] 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.
[0088] 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.
[0089] Meanwhile, FIG. 3 is a bottom perspective view showing a second embodiment of the wireless communication module 200 of the electronic detonation device with the dual antenna for a blasting system and the blasting system using the electronic detonation device according to the present disclosure. FIG. 4 is a view schematically showing a third embodiment of the wireless communication module 200 of the electronic detonation device with the dual antenna for a blasting system and the blasting system using the electronic detonation device according to the present disclosure.
[0090] Referring to FIGS. 3 and 4, each of the housing support protrusions 400 includes: a first supporting jig member 410 and a second supporting jig member 420 that clamp and hold the electronic detonator 100 by being moved in facing directions or opposite directions; and a jig moving part 430 positioned in the communication module housing part 210 and moving the first supporting jig member 410 and the second supporting jig member 420 in the facing directions or the opposite directions.
[0091] 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.
[0092] 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.
[0093] 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 whilst 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.
[0094] 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.
[0095] 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.
[0096] 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.
[0097] 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.
[0098] 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.
[0099] 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.
[00100] 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.
[00101] 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.
[00102] 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.
[00103] 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.
[00104] Each of the first supporting jig member 410 and the second supporting jig member 420 may have a travelling wheel member 460 that is rotatably positioned and protrudes downward.
[00105] When the wireless communication module 200 is placed on the ground or a floor, the travelling 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.
[00106] 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.
[00107] 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.
[00108] 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 whilst being moved in the opposite directions.
[00109] 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.
