Frequency-modulation type metal tracker

Abstract

Disclosed is a frequency-modulation type metal tracker, relating to the technical field of detecting instruments. The frequency-modulation type metal tracker includes a metal tracking transmitter which can modulate a wireless frequency-modulation tracking signal and broadcast the wireless frequency-modulation tracking signal to the outside through a metal object, and a metal tracking receiver which can receive the wireless frequency-modulation tracking signal from the metal tracking transmitter, demodulate the wireless frequency-modulation tracking signal, and reproduce information of the wireless frequency-modulation tracking signal. The present disclosure mainly solves the problem of how to provide equipment that can remotely detect and track metal objects. The frequency-modulation type metal tracker can detect and track metal objects such as wires and cables, steel bars, metal water supply and drainage pipes, metal heating and ventilation pipes, and metal racks which are buried in walls, under the ground, and in large objects, to facilitate use by operating personnel.
