The present disclosure relates to a device and a method thereof for operating an electronic detonator having a response relay function and, more particularly, to a device and a method thereof for operating an electronic detonator having a response relay function, wherein when a received command signal of a blasting control system is the same as a previously received command signal, presence or absence of a response signal of another electronic detonator adjacent within a preset distance is recognized and the same response signal as the response signal to be transmitted from another electronic detonator is transmitted instead to the blasting control system in accordance with a cycle of the recognized response signal of the corresponding another electronic detonator.
In general, an explosive is used for construction work such as blasting of bedrock for tunnel construction and blasting of an abandoned building. That is, by dividing a blasting object by section, a plurality of holes into which the explosive is inserted is drilled. The explosive is inserted into each of the drilled holes and connected to a blasting system. Detonation of the blasting object is conducted by detonating the explosive through manipulating the blasting system.
The blasting system is configured to include: a detonator, which is an initial explosive for detonating an explosive; and a blasting device configured to transmit, to the detonator, power and a command, which are required for operation of the detonator. In this case, an electronic detonator is mainly used as the detonator of the blasting system. The electronic detonator is installed on the side of the explosive, and a plurality of electronic detonators is connected to one blasting device.
The electronic detonator is provided with a structure in which when a command is transmitted from the blasting device, the plurality of electronic detonators connected to the corresponding blasting device operates simultaneously to detonate each explosive at the same time, and a structure in which a plurality of electronic detonators is set at different delay times, so that the plurality of electronic detonators is sequentially operated, thereby sequentially detonating each explosive.
In a connection system for the electronic detonators as described above, weakening of a detonator response signal may occur due to a number of causes. Consequently, a response signal according to a command of each corresponding electronic detonator is not transmitted to the blasting system, thereby causing the blasting system to perform re-communication. However, since signal quality is not improved unless a particular cause of the signal weakened due to a line condition is removed, there is a problem in that a probability of successful communication is low in multiple attempts for communication in the corresponding condition.
In this regard, Korean Patent Application Publication No. 2020-0082156 discloses “DETONATOR DEVICE, OPERATING METHOD OF DETONATOR DEVICE AND COMMUNICATION SYSTEM”.
The present disclosure is devised to solve the above-described problem, and an objective of the present disclosure is to provide a device and a method thereof for operating an electronic detonator having an response relay function, wherein when a received command signal of a blasting control system is the same as a previously received command signal, presence or absence of a response signal of another electronic detonator adjacent within a preset distance is recognized and the same response signal as the response signal to be transmitted from another electronic detonator is transmitted instead to the blasting control system in accordance with a cycle of the recognized response signal of the corresponding another electronic detonator.
According to the present disclosure for achieving the above objective, there is provided a device for operating an electronic detonator having a response relay function, the device including: a command signal reception unit configured to receive a command signal transmitted from a blasting control system; a response signal transmission unit configured to transmit a response signal responsive to the received command signal to the blasting control system; and a response signal delivery unit configured to transmit the corresponding response signal to the blasting control system when a response signal of another electronic detonator adjacent within a preset distance is recognized.
In addition, the device may further include an adjacent response signal recognition unit configured to recognize presence or absence of the response signal of the corresponding another electronic detonator adjacent within the preset distance when the blasting control system's command signal received by the command signal reception unit is the same as a previously received command signal.
In addition, the response signal of the corresponding another electronic detonator adjacent within the preset distance and recognized by the response signal delivery unit may be a response signal that is not transmitted to the blasting control system.
In addition, the response signal delivery unit may transmit instead the same response signal as the response signal to be transmitted from the corresponding another electronic detonator to the blasting control system in accordance with a cycle of the response signal of the corresponding another electronic detonator adjacent within the preset distance.
According to the present disclosure for achieving the above objective, there is provided a method for operating an electronic detonator having a response relay function, the method including: receiving, by a command signal reception unit, a command signal transmitted from a blasting control system; transmitting, by a response signal transmission unit, a response signal responsive to the received command signal to the blasting control system; and transmitting, by a response signal delivery unit, the corresponding response signal to the blasting control system when a response signal of another electronic detonator adjacent within a preset distance is recognized.
In addition, the method may further include, before the transmitting of the corresponding response signal to the blasting control system when the response signal of the corresponding another electronic detonator adjacent within the preset distance is recognized, recognizing presence or absence of the response signal of the corresponding another electronic detonator adjacent within the preset distance when the blasting control system's command signal received by the command signal reception unit is the same as a previously received command signal.
In addition, in the transmitting of the corresponding response signal to the blasting control system when the response signal of the corresponding another electronic detonator adjacent within the preset distance is recognized, the recognized response signal of the corresponding another electronic detonator adjacent within the preset distance may be a response signal that is not transmitted to the blasting control system.
In addition, in the transmitting of the corresponding response signal to the blasting control system when the response signal of the corresponding another electronic detonator adjacent within the preset distance is recognized, the same response signal as the response signal to be transmitted from the corresponding another electronic detonator may be transmitted instead to the blasting control system in accordance with a cycle of the response signal of the corresponding another electronic detonator adjacent within the preset distance.
The present disclosure relates to the device and the method thereof for operating the electronic detonator having the response relay function, wherein when the received command signal of the blasting control system is the same as the previously received command signal, the presence or absence of the response signal of another electronic detonator adjacent within the preset distance is recognized and the same response signal as the response signal to be transmitted from another electronic detonator is transmitted instead to the blasting control system in accordance with the cycle of the recognized response signal of the corresponding another electronic detonator, whereby there is an effect that when the blast control system attempts to re-communicate in a condition where the response signal of a particular electronic detonator is attenuated on a particular line, the response of the corresponding particular electronic detonator may be easily received.
In this way, the embodiment of the present disclosure may increase the reliability of the electronic detonator by reducing the possibility of failure due to poor communication in the blasting or control of the electronic detonator.

Describing with reference to
The command signal reception unit 110 receives a command signal transmitted from a blasting control system.
The response signal transmission unit 120 transmits a response signal responsive to the received command signal to the blasting control system.
The adjacent response signal recognition unit 130 recognizes presence or absence of a response signal of another electronic detonator adjacent within a preset distance when the blasting control system's command signal received through the command signal reception unit 110 is the same as the previously received command signal. Here, the preset distance is changed depending on line conditions, is set accordingly.
The response signal delivery unit 140 transmits the corresponding response signal to the blasting control system when the response signal of another electronic detonator adjacent within the preset distance is recognized.
In this case, the response signal of another electronic detonator, which is adjacent within the preset distance and recognized by the response signal delivery unit 140, is the response signal that is not transmitted to the blasting control system.
In more detail, a condition in which the response signal of the electronic detonator is attenuated may occur due to a high background current, a high communication line resistance, or the like. In such a condition, due to the response signal of the electronic detonator, that is, the characteristics of electric current communication, the electronic detonator consumes energy close to the limit of energy that may be consumed in the electric current communication on a line. In this case, the corresponding energy consumption may be received in a form of a supply voltage reduction in the electronic detonator adjacent to corresponding electronic detonator (i.e., similar to a voltage mode communication method transmitted by the blast control system), and thus the response of the adjacent electronic detonator may be detected.
The response signal delivery unit 140 may transmit instead the same response signal as the response signal to be transmitted from another electronic detonator to the blasting control system in accordance with a cycle of the response signal of the corresponding another electronic detonator adjacent within the preset distance.
As such, when the present electronic detonator receives the same command as the previously received command in a recommunication attempt condition of the blasting control system with respect to another electronic detonator adjacent within the preset distance, the present electronic detonator participates in the response to the blast control system with the same response signal and the same timing as the timing responded by another electronic detonator adjacent within the preset distance.
In addition, the embodiment of the present disclosure causes a signal to be amplified due to a parallel signal. In addition, when a response signal is recognized even by an electronic detonator disposed in a direction close to the blasting control system among adjacent directions, a response magnitude of the electronic detonator is generally inversely proportional to a distance to the blasting control system, so an increase in the response signal may be expected due to a propagation effect in which the electronic detonator close to the blasting control system participates in the response as recommunication attempts are repeated.
Describing with reference to
First, in step S100, a command signal transmitted from a blasting control system is received.
Next, in step S200, it is determined whether the blasting control system's command signal received after step S100 is the same as a previously received command signal.
In step S300, a response signal responsive to the received command signal is transmitted to the blasting control system when the received command signal of the blasting control system is not the same as the previously received command signal in step S200.
Meanwhile, in step S400, presence or absence of a response signal of another electronic detonator adjacent within a preset distance is recognized when the received command signal of the blasting control system is the same as the previously received command signal in step S200.
Next, in step S500, the corresponding response signal is transmitted to the blasting control system when the response signal of another electronic detonator adjacent within the preset distance is recognized. In this case, the recognized response signal of another electronic detonator adjacent within the preset distance is the response signal that is not transmitted to the blasting control system.
In step S500, the same response signal as the response signal to be transmitted from another electronic detonator may be transmitted instead to the blasting control system in accordance with the cycle of the response signal of the corresponding another electronic detonator adjacent within the preset distance.
