Description

remote blasting system

The present invention relates to a blasting system used in mines, civil engineering sites, etc., and in particular to a remote blasting system configured to improve workability and stability.

Blasting refers to the work of destroying a specific object using explosives at industrial sites such as mines or civil engineering sites. Blasting is usually accomplished through the process of forming a hole in an object to be blasted, loading explosives, and then igniting the explosives using a detonator. In general, a detonator is a general term used to detonate an explosive. Detonators are classified into electrical, non-electric, or electronic types depending on the method of activation. Here, electronic detonators have the disadvantages of being expensive, cumbersome to work with, and requiring a lot of work time compared to other detonators. Additionally, in the case of electric detonators, there is a risk of safety accidents occurring due to leakage current, static electricity, or lightning. For this reason, non-electric detonators are widely used in various industrial sites such as tunnels and mines.

Non-electric detonators are largely divided into co-detonators and connecting detonators. Here, the joint detonator refers to a detonator used to detonate an explosive by being loaded with an explosive in a blast hole, such as a blasting cap, and the connected detonator is used to transmit detonation energy to the joint detonator or other detonator, or to connect such energy transfer means. Refers to the detonator. Link primers are also referred to as surface primers in a relative sense to co-base primers. In addition, connection detonators are classified into, for example, Trunk-Line Delay Detonators (TLD), bunch connectors, starters, etc., depending on their purpose of use or structure. Additionally, the bunch connector or starter is also referred to as a bunch detonator or starter detonator. A non-electrical detonator is usually constructed by combining a detonator with a fuse or, preferably, a signal tube. The signal tube is intended to transmit the detonation signal, more specifically the detonation energy, to the detonator. The signal tube consists of gunpowder applied to the inside of a tube made of synthetic resin. In the signal tube, when the gunpowder inside the tube is detonated, the detonation energy is detonated through the inside of the tube to the detonator, detonating the detonator.

When blasting is performed using a non-electric detonator, first, one or more holes, i.e., blast holes, are formed in the object to be blasted, and a detonator, i.e., a hollow detonator, and explosives are loaded into each blast hole. Afterwards, connecting detonators such as TLD, bunch connector, starter, etc. are appropriately connected and combined with the co-detonator as needed. Here, the TLD or bunch connector is used to connect the detonation energy to multiple signal tubes, and the starter is equipped with a signal tube of 30 to 150 m in length and is mainly used to ensure a safe distance for workers from the blast hole. And a detonator or blaster is coupled to the connection detonator, that is, the signal tube of the connection detonator, to properly detonate the signal tube.

Figure 1 is a configuration diagram showing an example of a typical blasting system employing a non-electric detonator. In the drawing, the blasting system basically includes a detonator (1) and a blaster (2). And, if necessary, a detonator (3) is employed between the detonator (1) and the blaster (2). Here, the detonator 3 is also called a spark detonator or spark trigger. As the detonator 1, a co-detonator or a connected detonator is suitably applied. As described above, the signal tube (4) is coupled to the detonator (1). The signal tube (4) is detonated by the blaster (2) or detonator (3).

The blaster (2) and the detonator (3) are electrically coupled. The blaster (2) and the detonator (3) are connected through a conductor called the blast bus bar (5). The blaster 2 is equipped with an operation button to start blasting. When the operator presses the operation button, electrical energy is supplied from the blaster (2) to the detonator (3) through the blasting bus bar (5), and the detonator (3) uses the applied electrical energy to signal the signal tube (4). ) is detonated. And the detonation energy generated at this time detonates through the signal tube (4) and detonates the detonator (1), thereby igniting the explosive. Regarding the blasting system and detonator (3) described above, Republic of Korea Patent No. 10-1230156 (name: Detonator of non-electric detonator using spark detonator and blasting construction method using the same) and Registration Patent No. 10-1339081 (name: : Non-electric detonator and method using an electric blaster and a spark detonator), etc.

Figure 2 is a configuration diagram showing another configuration example of a blasting system using a non-electric detonator. The configuration of Figure 2 is disclosed in Patent Publication No. 10-2021-0144219 (name: blaster for non-electric detonator and detonation system using the same). In addition, in FIG. 2, components that are substantially the same as those in FIG. 1 described above are given the same reference numerals. In FIG. 2A, the blaster 6 is connected to the detonator 3 through the first blasting bus bar 5, and the blaster 8 is connected to the blaster 6 through the second blast bus bar 7. do. In addition, in FIG. 2B, the blaster 9 is connected to the detonator 1 through the signal tube 4, and the percussion device 8 is connected to the blaster 9 through the second blasting bus bar 7. The configuration of FIG. 2 is, for example, in the blasting system of FIG. 1, when the length of the blasting bus bar (5) is extended to ensure a safe distance for workers, the resistance value of the blast bus bar (5) increases, etc., causing damage by the detonator (3). This was done to solve the problem of unstable detonation operation. That is, the configuration of FIG. 2 is additionally provided with a percussion device (8) for operating the blasters (6, 9) and allows the worker to secure a safe distance by using the second blasting bus (7). .

However, the conventional blasting system employing the non-electric detonator described above has the following problems. When performing blasting, worker safety is a top priority. In the configuration of FIG. 1, the detonator 1 is detonated by the detonation energy from the blaster 2, and the blaster 2 is operated by an operator (explosives management and security officer). Therefore, in order to protect workers from shock caused by blasting, there is usually a safety distance of 200 to 300 m or more from the detonator (1), or more precisely, from the co-bottomed detonator to the blaster (2).

In the system of Figure 1, the detonator (1) and the detonator (3) are connected through the signal tube (4), and the detonator (3) and the blaster (2) are connected through the blasting bus (5), so during blasting work The work of installing the signal tube (4) and blast bus bar (5) must be carried out at a distance of 200 to 300 m or more. In addition, after the blasting operation, the signal tube (4) must be recovered. This becomes a very cumbersome task when carrying out blasting.

In addition, in the system of FIG. 1, a blast bus bar (5) and a signal tube (4) are used between the blaster (2) and the detonator (1), and at this time, the blast bus bar (5) is protected from blast shock and lightning strikes, etc. To ensure safety from unexpected explosion, the length of the signal tube (4) is set as long as possible. However, since the signal tube 4 cannot be reused, unlike the blasting busbar 5, the system results in a lot of loss of the signal tube 4. Excessive use of the signal tube (4) provides undesirable effects from an economic as well as environmental perspective.

In addition, in the system of FIG. 1, when the amount of signal tube 4 used is reduced and the length of the blasting bus bar 5 is extended, the risk due to lightning or leakage current increases, and the length of the blast bus bar 5 is increased by a certain amount or more. If it is increased, there is a possibility that blasting may fail due to an increase in the resistance value of the blasting bus 5, as described above.

In addition, in the configuration of FIG. 2, a percussion device 8 is additionally required in the configuration of the blasting system. In addition, since the percussion device 8 is operated by an operator, it is necessary to secure a sufficient distance between the detonator 1 and the percussion device 8. In other words, it is necessary to secure the length of the signal tube 4 and the first and second

blasting bus bars

5 and 7 of 200 to 300 m or more. This causes a lot of loss in the signal tube 4, as in FIG. 1.

Additionally, in Publication Patent No. 10-2021-0144219, it is disclosed that the blaster 9 and the percussion device 8 are connected wirelessly in the configuration of FIG. 2B. However, in the configuration of FIG. 2B, the percussion device 8 and the blaster 9 are configured as dedicated devices. That is, if the percussion device 8 or the blaster 9 is damaged, the percussion device 8 and the blaster 9 are replaced or discarded together. Therefore, in the configuration of FIG. 2b, there is a need to secure a sufficient distance between the blaster 9 and the detonator 1 to prevent the blaster 9 from being damaged by impact from blasting. And, as in FIG. 1, this causes a lot of loss in the signal tube 4.

In addition, the conventional blasting system physically combines the blaster (2, 6, 9) and the detonator (1) and blows the detonator (1) through a simple procedural process of manipulating the blaster (2) or the percussion gun (8). ) works. Therefore, there is a risk of misuse or improper use of the blasting system.

The present invention was created in consideration of the above circumstances, and its technical purpose is to provide a remote blasting system that can improve workability and stability during blasting.

In addition, the present invention has another technical purpose in providing a remote blasting system that can minimize the amount of signal tube usage while eliminating the need for a blast bus.

In addition, the present invention creates conditions in which workers (explosives management and security officers) can concentrate on blasting work and improves the overall precision of blasting work, thereby preventing very large economic losses caused by inappropriate blasting work and management. Another purpose is to provide a remote blasting system that can prevent

According to the present invention having the above-described configuration, the detonator and the blaster are connected wirelessly, so the blasting bus bar for connecting the blaster and the detonator is eliminated. Therefore, the problem of damage to the blast bus due to blast shock is eliminated, and the detonator can be installed close to the detonator. In other words, it is possible to minimize the use of physical connection means to transmit detonation energy to the detonator, such as a signal tube.

In addition, since the use of physical connection means to connect the detonator and blaster to the detonator is minimized, the work of installing blast busbars and signal tubes at a distance of 200 to 300 m or more is eliminated. In other words, workability due to blasting is significantly increased.

In addition, since the detonator and the detonator are connected wirelessly, a sufficient distance between the detonator and the detonator can be secured without any additional work. Accordingly, the safety of workers performing blasting work can be improved.

In general, blasting work using explosives requires very high precision. Improper blasting construction that goes against the basic design principles increases the risk of safety accidents, can cause overburden, residual holes, and various other negative consequences. These negative consequences result in significant economic losses. Blasting work includes drilling work to form a blast hole in the rock, charging work to install explosives and a co-bottom detonator in the blast hole, and connection work to connect a connecting detonator such as a starter to a detonator or blaster at the end of the tunnel. Generally, multiple workers are required for blasting work, and charging and connection work are usually performed simultaneously. However, at this time, the charging work requires a high degree of concentration, whereas the connection work is a very cumbersome work that involves installing blast busbars or signal tubes. The complexity of the connection operation has a very inadequate effect on maintaining the concentration of the charging operation. Decreased concentration in charging work can lead to various complex problems, such as increased vibration and noise during blasting, increased damage to the host rock and overburden caused by blasting, excessive residual hole generation, and increased risk of rockfall accidents. The present invention provides the effect of improving the worker's work concentration by eliminating the cumbersome work involved in blasting work. In addition, the present invention provides the effect of improving the safety of blasting work by improving the worker's work concentration, as well as improving economic efficiency, such as improving construction quality, reducing construction costs, and shortening the construction period.

Hereinafter, an embodiment according to the present invention will be described with reference to the drawings. However, the examples described below illustratively show one preferred embodiment of the present invention, and the examples are not intended to limit the scope of the present invention. The present invention can be implemented with various modifications without departing from its technical spirit.

Figure 3 is a system configuration diagram showing the configuration of a remote blasting system according to an embodiment of the present invention. In this embodiment, the remote blasting system includes a detonator (1), a detonator (10), and a blaster (20). Here, as the detonator 1, a non-electric detonator is preferably employed. The detonator 1 and the detonator 10 are combined through a conventional method. The detonator 1 and the detonator 10 are physically coupled through a detonation energy transfer means such as a fuse or signal tube 4. Additionally, as the detonator 1 in the drawing, a co-authored detonator or a connected detonator may be applied. The purpose or installation location of the detonator 1 to which the present invention is applied is not specified. In the present invention, as the detonator 1, any detonator that is physically coupled through a detonation energy transfer means such as the signal tube 4 and can be detonated by detonation energy from the detonator 10 can be applied in the same manner. .

Meanwhile, the detonator 10 and the blaster 20 are wirelessly coupled. The blaster 20 is used to operate the detonator 10 at a location that is a certain distance or more away from the detonator 10. The communication method between the detonator 10 and the blaster 20 is not specified. In a preferred embodiment of the present invention, the detonator 10 and the blaster 20 are coupled through LoRa (Long Range) communication. LoRa communication uses the frequency band of the ISM (Industry-Science-Medical) band (920.9 ~ 923.3 MHz in Korea) and is capable of long-distance wireless communication and low-power communication of around 16km. Additionally, in a preferred embodiment of the present invention, one or more repeaters may be provided between the detonator 10 and the blaster 20 for smoother communication between the two devices.

In addition, in the blasting system described above, the blaster 20 and the detonator 10 are coupled through wireless communication capable of long-distance communication, so the distance between the blaster 20 and the detonator 10 is arbitrarily set sufficiently long. It becomes possible. In other words, it is possible to easily and sufficiently secure the safety distance for workers by using the communication distance between the blaster 20 and the detonator 10.

In addition, the above system can secure a safe distance through wireless coupling between the blaster 20 and the detonator 10, making it possible to install the detonator 10 close to the detonator 1. do. Therefore, it is possible to eliminate the disadvantage of having to use a connecting detonator such as a signal tube (4) or a starter to secure a safety distance of 200 to 300 m or more.

As is well known, blasting work includes drilling work to form a blast hole in rock, etc., charging work to install explosives and a co-bottom detonator in the blast hole, and connection work to connect the detonator and blaster to the co-bottom detonator. Generally, multiple workers are required for blasting work, and charging and connection work are usually performed simultaneously. However, at this time, the charging work requires a high level of concentration, while the connection work involves the very cumbersome work of installing the blast bus bar and signal tube at a distance of 200 to 300 m or more. The complexity of this connection operation may have an inadequate effect on maintaining the concentration of the charging operation. Decreased concentration in charging work can lead to various complex problems, such as increased vibration and noise during blasting, damage to the host rock and increased overbreak due to blasting, occurrence of residual holes, and increased risk of rockfall accidents. The system provides the effect of improving the worker's work concentration by eliminating the cumbersome work involved in blasting work. In addition, this simplification of work content and the improvement of workers' concentration can promote the stability of blasting work and provide many positive effects, such as improving construction quality, reducing construction costs, and shortening the construction period.

Although not specifically shown in the drawings, the inlet 120 is preferably provided with a stopper that is detachable. Inside the inlet 120, an igniter 150 is installed close to the inlet 120. The igniter 150 is for coupling and detonating the signal tube (4). The igniter 150 is installed on the substrate 160, and a coupler 152 is installed on one side of the igniter 150, that is, the side opposite to the inlet 120. The signal tube 4 is fitted and coupled to the outside of the coupler 150.

FIG. 5 is a cross-sectional view showing the cross-sectional configuration of the igniter 150, which is a cross-sectional view taken along line A-A' of the igniter 150 in FIG. 4. In the drawing, the igniter 150 has a body 151. In this embodiment, the body 151 is made of, for example, a synthetic resin material and has a hexahedral shape. However, the material and shape of the body 151 are not specified. A fastening hole 151a is provided in the body 151 in the vertical direction.

The outer diameter of the coupler 152 is formed to a size corresponding to the inner diameter of the signal tube 4, and an inclined portion 152a is preferably provided at one end, that is, the end where the signal tube 4 is coupled. The inclined portion 152a is for easily coupling the signal tube 4 to the coupler 152. The coupler 152 is made of a conductive material such as copper. Preferably, the coupler 152 is fixedly coupled to the insertion groove 151b using, for example, an adhesive, or is fitted into the insertion groove 151b. Additionally, at this time, the other end of the coupler 152, that is, the end inserted into the insertion groove 151b, may also preferably be provided with an inclined portion.

Additionally, an insertion hole 151c is formed in the body 151 of the igniter 150 while communicating with the insertion groove 151b.

The lead wire 153 is composed of a core wire 153b made of a conductive material such as copper provided inside a covering layer 153a made of an insulating material. The lead wire 153 is inserted into the insertion groove 151b through the insertion hole 151c. The lead wire 153 is preferably disposed so that its terminal end is located adjacent to the end of the coupler 152, and the covering layer 153a is removed by a certain length to expose the core wire 153b to the outside. And the exposed core wire 153 is arranged to be spaced apart from the inner peripheral surface of the coupler 152.

A signal tube 4 is fitted to the outside of the coupler 152. As described above, the signal tube 4 is composed of a coating layer 4b made of gunpowder formed on the inner peripheral surface of the tube 4a made of synthetic resin. Although not specifically shown in the drawing, the coupler 152 and the lead wire 153 of the igniter 150 are electrically coupled to the internal circuit part, specifically the detonator part 12, which will be explained later. When the detonator 1 is detonated, a high voltage is applied to the coupler 152 and the lead wire 153, and the high voltage generates a spark between the coupler 152 and the core wire 153b of the lead wire 153. The spark generated from the coupler 152 detonates the gunpowder in the coating layer 4b located adjacent to the end of the coupler 152, and this detonation occurs in succession along the application layer 4b. do. Accordingly, the detonation energy generated by the spark in the coupler 152 is detonated toward the detonator 1 through the signal tube 4 to detonate the detonator 1.

In FIG. 4, a transparent window 100a, preferably made of a transparent material such as acrylic, is provided at a position corresponding to the igniter 150 of the housing 100. The transparent window 100a is intended to allow the operator to visually recognize the shape and position of the coupler 152 and easily insert the signal tube 4 into the coupler 152. The transparent window 100a can be removed as needed. In addition, in another embodiment of the present invention, the coupler 152 is installed so that its end protrudes toward the inlet 120 or the outside thereof so that the operator can easily couple the signal tube 4.

In addition, for example, an LED 130 is provided on the outside of the housing 100 as an operating status display means. The LED 130 is intended to inform the operator of the operating status of the detonator 4. The LED 130 is driven on/off or blinked depending on the operating state of the detonator 10. Additionally, an information display unit 140 is provided on the outer surface of the housing 100.

In FIG. 4, the board 160 is provided with a circuit unit for operating the detonator 10. Figure 6 is a configuration diagram showing the configuration of the operation circuit of the detonator 10. In the drawing, the detonator 10 includes a power supply unit 11, a detonation part 12, a control unit 13, and a communication unit 14.

The detonation part 12 basically includes a detonation voltage output unit 121, a charging unit 122, and a boosting unit 123. The detonation voltage output unit 121 is used to supply detonation voltage to the igniter 150 in FIGS. 4 and 5. Hereinafter, for convenience of explanation, the detonation voltage output unit and the output unit will be used interchangeably. The output unit 121 includes first and second output terminals VO1 and VO2 for outputting a detonation voltage. These output terminals VO1 and VO2 are electrically coupled to the coupler 152 and the lead wire 153 of the igniter 150, respectively. Here, the first output terminal (VO1) is electrically coupled to the charging unit 122, and the second output terminal (VO2) is coupled to the switching circuit (SW1). The switching circuit (SW1) is coupled to the digital output terminal (P3) of the control unit 13 and driven by switching by the control unit 13. The switching circuit (SW1) switches the second output terminal (VO2) according to the output voltage from the control unit 13. ) is coupled to or grounded to the first output terminal (VO1). The configuration of the switching circuit SW1 is not specified. In this embodiment, the switching circuit (SW1) includes a relay switch (RY1), and the relay switch (RY1) is driven by the transistor (T1). When the relay switch RY1 is in a non-driving state, that is, when no current flows through the coil L1, the relay contact points (a, b) are connected, and in the driving state, the relay contact points (a, c) are connected. When the relay switch RY1 is not driven, the first output terminal VO1 and the second output terminal VO2 are short-circuited by the relay switch RY1, so that the voltage between the two output terminals VO1 and VO2 is always set to be the same. That is, when the relay switch RY1 is in a non-driven state, sparks are reliably prevented from being generated between the coupler 152 and the lead wire 153 of the igniter 150.

The charging unit 122 is used to apply a high voltage to the output unit 121, and is preferably provided with a capacitor for charging and discharging. The boosting unit 123 is used to boost the power supply voltage (V1) and charge the charging unit 122 with a high voltage. In this embodiment, the booster 123 includes a transformer 1230, a MOS transistor (T2) for switching and driving the transformer 1230, and a diode (D1) for preventing reverse current. The gate of the transistor T2 is coupled to the digital output terminal (P1) of the control unit 13 and is switched and driven by the control unit 13. The control unit 13 switches and drives the transistor T2 at a rate of, for example, 30 KHz to charge the charging unit 122 with a high voltage of, for example, 400 to 500 V. In another embodiment of the present invention, the boosting unit 123 may be provided with an oscillation means. At this time, the oscillation means performs oscillation according to a control signal from the control unit 13, and the oscillation output is applied to the gate of the transistor T2 to drive the transistor T2 in switching. The configuration of the boosting unit 123 is not specified, and any configuration that can appropriately charge the charging unit 122 can be preferably employed.

The detonation part 12 is preferably provided with a charging voltage detection unit 124. The charging voltage detection unit 124 includes a resistance voltage dividing circuit (R1, R2) coupled in parallel with the charging unit 122. In the resistor voltage divider circuit, the connection nodes of the resistors (R1, R2) are coupled to the analog input terminal (A1) of the control unit 13 through the current limiting resistor (R3) and the overvoltage prevention Zener diode (Z1). Here, the resistance voltage dividing circuits R1 and R2 are used to convert the high voltage charged in the charging unit 122 into a low voltage that can be recognized by the control unit 13.

Additionally, the detonator part 12 is provided with a discharge unit 125 for discharging the charging voltage of the charging unit 122. The discharge unit 125 includes a current path for coupling the voltage charging end of the charging unit 122, that is, the positive (+) terminal of the charging and discharging condenser 122, with ground. This current path is, for example, coupled in parallel with the charging unit 122 and has a current limiting resistor R6 and a transistor T3. The resistor R6 is used to prevent excessive discharge current from flowing from the charging unit 122 to the ground and to appropriately set the discharge time of the charging voltage. The transistor T3 is for controlling the current path through the resistor R6. The gate of the transistor T3 is coupled to the digital output terminal (P2) of the control unit 13. When necessary, the control unit 13 turns on the transistor T3 to discharge the charging voltage of the charging unit 122. The discharge unit 125 is used to prevent the detonation operation from being improperly performed due to the charging voltage remaining in the charging unit 122. The discharging unit 125 is appropriately driven when the operator stops charging while charging of the charging unit 122 is completed or in progress.

In addition, the detonation part 12 is preferably provided with a detonation detection unit 126 for detecting whether the signal tube 4 has been detonated normally. The detonation detection unit 126 is used by the control unit 13 to recognize the voltage level of the output terminal (VO1 or VO2). In the drawing, a resistor voltage dividing circuit is coupled to the first output terminal (VO1) of the output unit 121. The resistance voltage dividing circuit includes resistors (R7, R8) connected in series between the first output terminal (VO1) and ground. The resistor voltage dividing circuits (R7, R8) are used to convert the voltage level of the first output terminal (VO1) into a voltage level that the control unit 13 can recognize. The connection nodes of the resistors (R7, R8) are coupled to the interrupt terminal (INT) of the control unit 13 through the current limiting resistor (R9) and the overvoltage prevention Zener diode (Z2). In the detonation detection unit 126, the resistors R7 and R8 are coupled in parallel with the charging unit 122, so before the detonation operation is performed, that is, in a state in which the charging unit 122 is charged with a high voltage, the interrupt terminal ( INT) is set to high level. On the other hand, when a detonation operation on the signal tube 4 is performed by the detonator part 12, that is, when a spark is generated between the coupler 152 and the lead wire 153 in the igniter 150 of FIG. 5, The first and second output terminals VO1 and VO2 of the output unit 121 are short-circuited, and the second output terminal VO2 is coupled to the ground through the switching circuit SW1. Therefore, the moment a spark is generated, the voltage level of the interrupt terminal (INT) of the control unit 13 drops to the low level. The control unit 13 determines whether detonation has been performed on the signal tube 4 based on the falling edge of the interrupt (INT) voltage.

The control unit 13 includes a microcomputer. A microcomputer has internal program memory and data memory. A control program for controlling the detonator 10 is stored in the program memory. The control unit 13 controls the entire device according to the control program. Additionally, the control unit 13 communicates with the blaster 20 through the communication unit 14.

The transmitting and receiving modules constituting the communication unit 14 are not limited to specific ones. Additionally, the interface and communication method between the control unit 13 and the communication unit 14 will be appropriately set according to the specifications of the transmitting and receiving module. In this example, the control unit 13 and the communication unit 14 perform serial communication. The control unit 13 and the communication unit 14 are equipped with Tx and RX ports for serial communication, and the control unit 13 is allocated appropriate ports, such as digital output terminals, for the Tx and Rx ports. Since the interface and operation for serial communication between the control unit 13 and the communication unit 14 are general matters, detailed description thereof will be omitted. And, the antenna 141 is coupled to the antenna port (ANT) of the communication unit 14. The antenna 141 is preferably composed of wiring in a predetermined pattern formed on the substrate 160.

Additionally, as described above, the detonator 10 is provided with an LED 130. The anode side of the LED 130 is coupled to the power supply voltage (V1), and the cathode side is coupled to the digital output terminal (P4) of the control unit 13 through a resistor (R10). The control unit 13 displays the operating state of the detonator 10 by turning the LED 130 on/off or blinking it.

An antenna 202 for communication with the detonator 10 is provided at the top of the housing 201. A display 203 is provided on the front of the housing 201 to display the operating status of the device and provide various selection menus to the operator.

And, the charging button 206 and the blasting button 207 are for the operator to operate the detonator 10. The operation of the detonator 10 according to the operation of the charging button 206 and the blasting button 207 will be described in more detail later. Additionally, the housing 201 is provided with a display unit 208 such as an LED and a speaker 209. These are intended to provide various operation information of the blasting system to workers as visual or auditory information.

In the drawing, the blaster 20 includes a display 203 as well as a power unit 80, an input unit 81, a control unit 82, and a communication unit 83. The power supply unit 80 includes a battery. A secondary battery is preferably used as the battery, and although not specifically shown in the drawing, a connector is provided for charging the battery. The power supply unit 80 is for supplying operating power (V2) to the entire device. Although not specifically shown in the drawing, when the operator presses the power button 204 (FIG. 7), operating power V2 is supplied from the power supply unit 80 to the entire device.

The input unit 81 includes a plurality of operation buttons 204 to 207 shown in FIG. 7, a touch panel, and interfaces related thereto. The touch panel is installed on the display 203 as described above. The input unit 81 is general.

The communication unit 83 is substantially the same as the communication unit 14 in FIG. 6. The communication unit 83 is equipped with a transmission and reception module for LoRa communication and communicates with the control unit 82 based on serial communication. Additionally, an antenna 202 is coupled to the communication unit 83. Although FIG. 7 shows an example in which a rod-shaped antenna is used as the antenna 202, the antenna 202 may be configured with a predetermined wiring pattern provided on the substrate.

Additionally, a speaker 209 and LEDs (LED1 to LED3) are coupled to the digital output terminals (P1 to P4) of the control unit 82. Here, the speaker 209 is for the control unit 82 to output a warning sound such as a beep, and the LEDs (LED1 to LED3) constitute the display unit 208 in FIG. 7. The display unit 208 preferably includes LEDs (LED1 to LED3) that output different color lights of red, green, and blue. The control unit 82 provides status information of the blasting operation by appropriately setting the color of the display unit 208.

Additionally, in a preferred embodiment of the present invention, the blaster 20 may be provided with a second communication means for the control unit 82 to communicate with an external device through wired or wireless communication. At this time, as a communication means, for example, an interface for wired communication such as USB (Universal Serial Bus) or a communication module for wireless communication such as Bluetooth or Wi-Fi may be employed. And, the control unit 82 provides blasting data to an external device or receives information necessary for blasting through such communication means. The blasting-related information that the control unit 82 receives from an external device may preferably include information on the detonator 10 used for blasting, that is, the detonator 10 ID.

Next, the operation of the system with the above configuration will be described. When blasting is performed using the blasting system according to the present invention, one or more blast holes are formed in the object to be blasted in the same manner as before, and explosives are charged to each blast hole. Additionally, to detonate the explosive, a detonator such as a co-detonator or a connected detonator is placed and connected. Then, the detonator (10) is connected to the appropriate detonator (1) through the signal tube (4). Preferably, the detonator 10 is used after being properly registered with the blaster 20. Registration of the detonator 10 with the blaster 20 can be effected via communication coupling, i.e. network pairing. Network pairing is performed at an appropriate time before or after the operator engages the detonator (10) to the signal tube (4). Network pairing can be performed automatically or manually. Hereinafter, the case where network pairing is performed manually will be described as an example.

Network pairing between the blaster 20 and the detonator 10 is performed with both devices in operation. When an operator wants to perform blasting using this blasting system, he or she first operates the power button 204 of the blaster 20 and the power switch 110 of the detonator 10 to put both devices in an operating state. It is set.

When the device is started by the power switch 110, the detonator 10 sets the detonator part 12 to an inactive state in the initial state and waits for a pairing request from the blaster 20. In the standby state, the control unit 13 sets the transistors T1 and T2 to the off state and the transistor T3 to the on state. Accordingly, the boosting unit 123 is set to a non-driving state and the charging operation for the charging unit 122 is not performed, and the charging unit 122 is grounded through the discharging unit 125, that is, the resistor R6, so the charging unit ( The charging voltage of 122) is maintained at the ground level. In addition, since the relay switch (RY1) of the output unit 121 is connected between the contact points (a, b), the first output terminal (VO1) and the second output terminal (VO2) for outputting the detonation voltage to the igniter 150 are mutually connected. short-circuited. That is, when the detonator 10 is in a standby state, the charge level of the charging unit 122 is set to the '0' level, and the first output terminal (VO1) and the second output terminal (VO2) for outputting the detonation voltage are short-circuited with each other. are set to the same voltage. Therefore, improper operation of the igniter 150 due to leakage current or lightning is reliably prevented.

When executing network pairing, the operator executes a search function for the detonator 10 through the input unit 81 of the detonator 20. When the detonator search function is selected, the control unit 82 transmits a request message requesting identification information, that is, ID information, to the detonator 10 through the communication unit 83. Transmission of the request message is performed, for example, by broadcasting. When the detonator 10 receives an ID request message from the blaster 20, it transmits its ID to the blaster 20. The blaster 20 outputs the ID information received from the detonator 10 through the display 203. Then, when the operator selects the ID of the detonator 10 to be used for blasting, the control unit 82 executes network pairing by transmitting an approval command to approve network access to the corresponding detonator 10, and then the corresponding detonator 10 Communication is performed with (10).

In a preferred embodiment of the present invention, when the blaster 20 is equipped with the above-described second communication means, the manager managing the blasting site sends the ID information of the detonator to be used for blasting to the blaster 20 in advance. You can register. And the control unit 82 displays only the ID information corresponding to the pre-registered detonator 10 among the ID information of the detonator 10 received through the communication unit 83 on the display 203, thereby preventing inappropriate detonators from being detected. This prevents (10) from being used.

Additionally, in another preferred embodiment of the present invention, the blaster 20 may be equipped with an imaging means such as a camera. This imaging means is for reading the information display unit 140 provided in the housing 100 of the detonator 10 in FIG. 4. In this implementation example, instead of selecting the ID information displayed on the display 203, the operator reads and inputs the ID information in the information display unit 140 provided in the detonator 10 to select the detonator 10 to be currently used. You get to choose. This can provide the effect of reliably preventing workers from misidentifying the detonator to be used for blasting.

In addition, during the network pairing operation described above, the control unit 13 in FIGS. 4 and 6 displays the pairing progress and completion status as visual information by blinking or lighting the LED 130. In addition, in FIG. 8, when network pairing with the detonator 10 is completed, the control unit 82 of the blaster 20 provides distance information between the blaster 20 and the detonator 10, and the detonator 10. It displays the frequency reception sensitivity for . Here, the reception sensitivity information can be obtained by the control unit 82 reading the register value provided in the communication unit 83, and the distance information can be calculated programmatically by the control unit 822 based on the increase or decrease in reception sensitivity. do. In a preferred embodiment, network pairing between the detonator 20 and the detonator 10 is performed with both devices located adjacent to each other. Then, the control unit 82 stores the reception sensitivity of the detonator 10 at the time of network pairing as an initial value, and then adjusts the distance between the blaster 20 and the detonator 10 based on the change in reception sensitivity. It is calculated. The display of distance information is to enable the worker to recognize the safe distance from the detonator (10), and the display of reception sensitivity is to warn that the detonator (10) is outside the control range of the blaster (20). . The operator can take appropriate measures, such as using a repeater, based on the reception sensitivity level displayed on the blaster 20.

The operator couples the signal tube 4 to the coupling port 152 of the detonator 10 in FIGS. 4 and 5 and operates the detonator 10 using the blaster 20. The detonation operation by the detonator 10 is performed using the charge button 206 and the blast button 207 of the blaster 20. The operator first presses the charging button 206 of the blaster 20 to finish charging the charging part 122 of the detonator 10, and then presses the blasting button 207 again to charge the signal tube 4. The detonation is carried out.

In a preferred embodiment of the present invention, when the operator presses the charging button 206 of the blaster 20, the control unit 82 first checks the register value of the communication unit 83 to connect the blaster 20 and the detonator ( 10) It is determined whether a safety distance is secured between the two and whether the communication status between the blaster 20 and the detonator 10 is normal. In other words, it is determined whether the current blasting environment is normal. Here, the reference value for determining whether the blasting environment is normal can be registered programmatically in the blaster 20, or the operator can register it through the input unit 81. If the control unit 82 determines that the blasting environment is inappropriate, it displays abnormal condition information on the display 203 or issues an alarm through other alarm means, that is, the speaker 209 and the display unit 208. Meanwhile, if the current blasting environment is normal, the control unit 82 transmits a charging command to the detonator 10.

In the detonator 10, when a charging command is received from the blaster 20, the control unit 13 sets the discharge unit 125 of the detonator part 12 to a non-driving state and drives the boosting unit 123. Thus, a charging operation for the charging unit 122 is performed. That is, the control unit 13 turns off the transistor T3 of the discharge unit 125 and switches and drives the transistor T2 of the booster unit 123 at a predetermined frequency. Also, at this time, the transistor T1 of the output unit 121 is still set to the off state, so that the first and second output terminals VO1 and VO2 remain short-circuited. Additionally, when the above-described charging operation is performed, the control unit 13 detects the charging voltage of the charging unit 122 through the charging voltage detection unit 124. And when the charging voltage rises above a certain voltage, that is, a voltage value that can drive the igniter 150, the control unit 13 transmits a charging completion message to the blaster 20 through the communication unit 14. The charging operation for the charging unit 122 is performed until the charging unit 122 is charged to a preset maximum charging voltage value. In addition, in a preferred embodiment of the present invention, the control unit 13 transmits the charging voltage recognized through the charging voltage detection unit 124 to the blaster 20 in a certain time unit, thereby allowing the operator to proceed with charging of the detonator 10. This allows you to visually check the status.

In a preferred embodiment of the present invention, the above-mentioned charging operation is carried out only while the operator holds down the charging button 206 of the blaster 20. That is, the operator can stop the charging operation by stopping operation of the charging button 206. When the operator stops operating the charging button 206, the control unit 82 transmits a charging stop command to the detonator 10. And, when a charging stop command is received, the control unit 13 of the detonator 10 sets the boosting unit 123 to a non-driving state and drives the discharging unit 124 to increase the charging power of the charging unit 122. It is discharged.

In the blaster 20, when a charging completion message is received from the detonator 10, the control unit 82 informs the operator through the display 203 or the alarm means 208 and 209 that charging has been completed normally. Afterwards, the operator can execute a blasting operation by manipulating the blasting button 207. When the operator operates the blast button 207, the control unit 82 transmits a detonation command to the detonator 10. When a detonation command is received, the control unit 13 in the detonator 10 turns on the transistor T1 of the output unit 121. When the transistor T1 is turned on, the contact points (a, c) of the relay switch (RY1) are short-circuited, and the second output terminal (VO2) is coupled to ground. Accordingly, the charging current of the charging unit 122 is set to a state in which it can flow to ground through the first and second output terminals (V01, VO2), so that the coupler 162 and the lead wire 160 of the igniter 150 in FIG. 5 Sparks are generated between them. As described above, when a spark is generated from the igniter 150, the signal tube 4 is detonated and the detonation energy is detonated toward the detonator 1 through the signal tube 4, thereby performing blasting.

When a spark is generated between the first and second output terminals (V01 and VO2) of the output unit 121, the first output terminal (VO1) is connected to the ground side and its voltage level is set to a low level. Accordingly, a low-level interrupt signal is input to the interrupt terminal (IINT) of the control unit 13 through the detonation detection unit 126. The control unit 13 determines whether the detonation operation is normally performed based on the input of the interrupt signal. When an interrupt signal is input, the control unit 13 transmits a detonation completion message to the blaster 20. Then, the blaster 20 ends the blasting operation when the control unit 82 outputs a detonation completion message through the display 203. Additionally, the control unit 82 stores blasting information, such as blasting time, detonator ID, blasting distance, and radio wave sensitivity, in the data memory. The data stored in this way can be later viewed by the operator through the input unit 81. Additionally, when the control unit 82 receives a detonation completion message from the detonator 10, it releases the network pairing for the corresponding detonator 10.

In a preferred embodiment of the present invention, when the detonator 10 is activated according to the above operation, the detonator 10 is then set to an operation-inhibited state. The operation prohibition setting is to prevent the detonator 10 from attempting network pairing with the blaster 20 during another subsequent blasting due to the detonator 10 still operating even after blasting is performed. The operation prohibition setting of the detonator 10 can be performed through various methods.

First, the operation prohibition setting can be configured so that the detonator 10 sets itself. In FIG. 6, when the interrupt signal (INT) is input from the detonation detection unit 126 by the above-described blasting operation, the control unit 13 first transmits a detonation completion message to the blaster 20 and then activates the detonator 10. It is set to operation prohibited. At this time, the operation prohibition state is executed programmatically, and then the control unit 13 stops all control operations for the detonator 10.

Additionally, the operation prohibition setting can be executed through interlocking of the detonator 10 and the blaster 20. In this example, when the detonation completion message is received from the detonator 10, the blaster 20 transmits an operation prohibition command to the detonator 10. Also, at this time, the control unit 82 of the blaster 20 may inquire whether to disable the detonator 10 through the display 203 and transmit an operation prohibition command according to the operator's selection. And, in the same manner as the above-described operation, the control unit 13 programmatically sets the detonator 10 to an operation-inhibited state.

Additionally, the operation prohibition setting can be performed by the blaster 20 itself. In this example, when the blaster 20 receives the detonation completion message from the detonator 10, the control unit 82 sets the ID of the corresponding detonator 10 to the used ID, and thereafter, the detonator 20 with the corresponding ID Control operations such as network pairing are not performed on the device 10.

Above, embodiments according to the present invention have been described. However, the present invention is not limited to the above-described embodiments and can be implemented with various modifications without departing from the technical spirit.

For example, in the above-described embodiment, it was explained that the blaster 10 is provided with a charging button 206 and a blasting button 207, but this means that when the operator operates the blasting button 207, the detonator ( The control unit 82 of 10) can be configured to sequentially perform the charging operation and detonation operation.
