ANTENNA FOR WIRELESS PRIMER DETONATOR, WIRELESS PRIMER DETONATOR, AND WIRELESS DETONATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an antenna for a wireless primer detonator, a wireless primer detonator including the antenna for a wireless primer detonator, and a wireless detonation system using the wireless primer detonator that can efficiently receive ignition energy or energy for driving an electronic circuit and control signals without being affected by the positional relation between an operating-side antenna and an antenna for a wireless primer detonator.;SOLUTION: In an antenna 11 for a wireless primer detonator of the present invention, when the axial direction of a soft magnetic core is defined as a Z-axis, a direction orthogonal to the Z-axis is defined as an X-axis, and a direction orthogonal to both the Z-axis and the X-axis is defined as a Y-axis, a Z-axis antenna 11Z formed by a Z-axis coil made of a conductive wire wound around a soft magnetic core and the Z-axis and the soft magnetic core, an X-axis antenna 11X formed by an X-axis coil made of a conductive wire wound around a soft magnetic core and the X-axis and the soft magnetic core, and a Y-axis antenna 11Y formed by Y-axis coil made of a conductive wire wound around a soft magnetic core and the Y-axis and the soft magnetic core are disposed in proximity of each other.;SELECTED DRAWING: Figure 12;COPYRIGHT: (C)2018,JPO&INPIT
