Title: Electronic detonation device with dual antenna for blasting system and blasting system using same

Description:
TECHNICAL FIELD 
     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 
     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.

     BEST MODE 
     Hereinafter, the present disclosure will be described in detail. 
     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. 
       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. 
     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 . 
     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,  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. 
     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. 
     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 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 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 . 
     Further, the user terminal  500  may transmit respective blast commands including blast delay times to a plurality of electronic detonators  100 .
