| Abstract |
Recently, electronic detonators are being used for blasting work at construction or civil engineering sites. In this study, an electronic detonator circuit was designed using semiconductor devices. The proposed electronic detonator circuit consists of a ring oscillator and a high voltage generator to cause insulation breakdown of the detonating condenser, and a detonation state detection circuit to check the states before and after insulation rupture. The high voltage generator was designed to sufficiently satisfy the voltage (6.5 ∼ 7.5 [V]) and current (<10 [㎂]) required for detonation, and the voltage ranged from 6.08 to 9.02 [V] and the current ranged from 3.04 to 4.51 [㎃]. The detonation state detection circuit accurately detects the state before and after detonation, allowing the operation of the internal circuits to stop after detonation. |
