Miniaturized mining low-frequency emergency transmitting node based on shape memory structure

Abstract

The invention discloses a mining miniaturized low-frequency emergency transmitting node based on a shape memory structure, which comprises a wrist strap, an annular cavity is formed in the wrist strap, a low-frequency transmitting antenna is arranged in the annular cavity, the outer wall of the wrist strap is fixedly connected with a control shell, the side surface of the control shell is detachably connected with a cover plate, and the cover plate is fixedly connected with the wrist strap. A core device plate is fixedly connected to the bottom of an inner cavity of the control shell, a voltage output mechanism is fixedly connected to the top face of the core device plate, the two ends of the low-frequency transmitting antenna are electrically connected with the voltage output mechanism, a control mechanism is arranged on the cover plate, and the control mechanism is electrically connected with the voltage output mechanism. The low-frequency transmitting antenna is composed of a memory metal wire and a ferromagnetic material layer, the memory metal wire is bent in a sine shape in the annular cavity, and the ferromagnetic material layer is arranged on the outer wall of the memory metal wire in a sleeving mode.

Description

technical field [0001] The invention relates to the technical field of low-frequency communication, in particular to a mine-used miniaturized low-frequency emergency signaling node based on a shape memory structure. Background technique [0002] When a disaster occurs in an underground mine, emergency response is much more difficult than in other working environments. The communication between the existing surface and the underground mine mainly adopts the wired communication mode. Using a wired communication network for information transmission, when an emergency occurs, the anti-destructive ability is weak and the persistence is poor, resulting in the interruption of communication between the ground and the mine, which brings great difficulties to early warning, command, rescue and other work. In order to achieve unlimited communication signal transmission not affected by disasters, low-frequency electromagnetic waves with great penetrating power to the medium have become...
