Title:
MCU-CONTROLLED NONELECTRIC DETORNATOR TRIGGERING APPARATUS, AND NONELECTRIC DETORNATOR TRIGGERING METHOD AND TRIGGERING SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/075878
Kind Code:
A1
Abstract:
The present invention relates to an MCU-controlled nonelectric detonator triggering apparatus, and a nonelectric detonator triggering method and triggering system using same, the apparatus triggering a nonelectric detonator by igniting, with a spark caused by an electric discharge, a signal tube connected to the nonelectric detonator. More specifically, the nonelectric detonator triggering apparatus, in which a spark terminal to be ignited is connected through a high voltage-side interruption switch (220) of a normally open (NO) state and the high voltage-side interruption switch (220) is switched to ON by an MCU (231) that operates when a low voltage is applied thereto, is used for triggering only when a blaster machine (300) applies the low voltage, and then applies a high voltage, and thus triggering due to other electrical risk factors at a blasting site are fundamentally prevented.
