Abstract

A device and a method thereof for operating an electronic detonator having an auxiliary power function are proposed. The device is configured to include a power supply unit configured to supply power to a power source unit of the detonation capacitor and a power source unit of the operation capacitor, a power state determination unit configured to determine a state of the power charged in the power source unit of the operation capacitor, and an auxiliary power supply request unit configured to request auxiliary power supply to the power source unit of the detonation capacitor when the determined state of the power charged in the power source unit of the operation capacitor falls within a preset abnormal power state range.

First claim

The invention claimed is:

1. A device for operating an electronic detonator having an auxiliary power function, the device operating the electronic detonator configured to include a detonation capacitor and an operation capacitor, which are separated by two respective power sources, and comprising:
a power supply unit configured to supply power to a power source unit of the detonation capacitor and a power source unit of the operation capacitor;
a power state determination unit configured to determine a state of the power charged in the power source unit of the operation capacitor; and
an auxiliary power supply request unit configured to request auxiliary power supply [to] from the power source unit of the detonation capacitor when the determined state of the power charged in the power source unit of the operation capacitor falls within a preset abnormal power state range,
wherein a circuit structure is configured to comprise a path through which the power of the power source unit of the detonation capacitor is supplied to the power source unit of the operation capacitor, and
wherein the auxiliary power supply request unit supplies the power charged in the power source unit of the detonation capacitor to the power source unit of the operation capacitor through the path included in the circuit structure when the state of the power charged in the power source unit of the operation capacitor is less than or equal to preset power or is lost and falls within the abnormal power state range, so as to prevent the loss of the electronic detonator function.

2. The device of claim 1 , wherein the power state determination unit determines the state of the power charged in the power source unit of the operation capacitor when blasting is started after power charging of the power source unit of the detonation capacitor and the power source unit of the operation capacitor is completed.

3. The device of claim 1 , wherein the auxiliary power supply request unit makes the auxiliary power charged in the power source unit of the detonation capacitor to be supplied to the power source unit of the operation capacitor when the operation capacitor is damaged by a blasting shock.

4. A method for operating an electronic detonator having an auxiliary power function, the method operating the electronic detonator configured to include a detonation capacitor and an operation capacitor, which are separated by two respective power sources, and comprising:
supplying, by a power supply unit, power to a power source unit of the detonation capacitor and a power source unit of the operation capacitor;
determining, by a power state determination unit, a state of the power charged in the power source unit of the operation capacitor; and
requesting, by an auxiliary power supply request unit, auxiliary power supply from the power source unit of the detonation capacitor when the determined state of the power charged in the power source unit of the operation capacitor falls within a preset abnormal power state range,
further comprising:
when the state of the power charged in the power source unit of the operation capacitor is less than or equal to preset power or is lost and falls within the abnormal power state range, by the step of requesting, by the auxiliary power supply request unit, auxiliary power supply to the power source unit of the detonation capacitor,
the power charged in the power source unit of the detonation capacitor is supplied to the power source unit of the operation capacitor through the path included in the circuit structure, so as to prevent the loss of the electronic detonator function.

5. The method of claim 4 , wherein, in the determining of the state of the power charged in the power source unit of the operation capacitor, the state of the power charged in the power source unit of the operation capacitor is determined when blasting is started after power charging of the power source unit of the detonation capacitor and the power source unit of the operation capacitor is completed.

6. The method of claim 4 , wherein, in the requesting of the auxiliary power supply to the power source unit of the detonation capacitor when the determined state of the power charged in the power source unit of the operation capacitor falls within the preset abnormal power state range, the auxiliary power charged in the power source unit of the detonation capacitor is made to be supplied to the power source unit of the operation capacitor when the operation capacitor is damaged by a blasting shock.
