OBSTACLE EXPLORATION DEVICE OF EXCAVATOR AND OBSTACLE EXPLORATION METHOD OF EXCAVATOR

摘要

PROBLEM TO BE SOLVED: To provide an obstacle exploration device of an excavator capable of exploring a metal obstacle.;SOLUTION: An electromagnetic wave transmitter for transmitting a magnetic field 10 that is an electromagnetic wave and temporally changes into the ground and an electromagnetic wave receiver for receiving an inductive magnetic field 11 by a metal obstacle 9 caused by receiving the electromagnetic wave transmitted from the electromagnetic wave transmitter and propagating in the ground are installed in an excavator 1, and a phase change analyzer for analyzing a change in a phase when the metal obstacle 9 in the electromagnetic wave received by the electromagnetic wave receiver exists and when the metal obstacle 9 does not exist is included.;COPYRIGHT: (C)2013,JPO&INPIT
