Abstract

The invention belongs to the technical field of wireless communication, and discloses a through-the-earth magnetic field communication device. The device comprises a signal generating device and a signal receiving device, wherein the signal generating device comprises a permalloy magnetic field generator. The permalloy magnetic field generator comprises capacitors, a coil and a permalloy magneticcore. The permalloy magnetic core is a cuboid magnetic core made of an iron-nickel alloy material. The cuboid magnetic core is formed by superposing and bonding a plurality of cuboid magnetic sheets.The coil is a copper enameled wire, and the coil is wound at the central position of the permalloy magnetic core. The capacitors are connected with two ends of the coil in parallel. The signal receiving device comprises an atomic magnetometer, and the mullite magnetic field generator and the atomic magnetometer form a magnetic induction through-the-earth communication channel. Compared with a traditional ferrite magnetic core, the device has higher magnetic conductivity, and can improve the intensity of the emitted magnetic field.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an earth-penetrating magnetic field communication device. Background technique [0002] The wired communication facilities between the underground and the ground are vulnerable to natural disasters, emergency accidents and other factors, resulting in communication paralysis. The existing underground wireless communication system is based on the principle of electromagnetic wave transmission, which has weak communication signals, unstable channels, and poor diffraction and transmission communication capabilities. Shortcomings. [0003] The magnetic field penetrating communication system uses low-frequency magnetic fields as the carrier of signal propagation, and the channel is not affected by geological structures, and has stronger penetrating ability than electromagnetic wave communication methods. In the prior art, there is research on using a ferrite mag...
