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.
