Abstract: A device and a method thereof for operating an electronic detonator having a response relay function are proposed. The device includes 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.

Abstract: A detonator includes a control circuit and a charging circuit. The control circuit receives a first signal transmitted using a voltage applied to a cable by a blasting device and transmits a second signal to the blasting device using a current flowing to the cable. The charging circuit performs a charging operation by receiving the voltage through the cable. The charging circuit stops the charging operation while the control circuit transmits the second signal to the blasting device.

Abstract: An apparatus and method for searching for an unregistered detonator in a detonator list and confirming an ID are disclosed. The apparatus is being provided in control equipment and includes a lower first digit ID confirmation request unit that requests a detonator to confirm an ID for a preset lower first digit, a lower first digit ID confirmation unit that receives response data to the ID confirmation request for the preset lower first digit from the detonator, and confirms the ID for the lower first digit of the detonator through the received response data, a full ID confirmation request unit that requests the detonator for which the ID for the lower first digit is confirmed to confirm a full ID, and a full ID confirmation unit that receives response data to the full ID confirmation request from the detonator and searches for and confirms the full ID of the detonator.

Abstract: A communication system includes a transmitter and a receiver connected through a cable. The transmitter transmits a first signal to the receiver using a voltage applied to the cable. A control circuit of the receiver receives the first signal and transmitting a second signal to the transmitter using a current flowing to the cable. A charging circuit of the receiver performs a charging operation by receiving the voltage through the cable and supplying a driving voltage to the control circuit. The control circuit includes a filter generating a second voltage by extracting a voltage within a reference range from a peak voltage of a first voltage and a voltage meter extracting the first signal by measuring the second voltage.
