A magnetic induction waveguide communication device and method for safety monitoring of underground pipeline network

Abstract

The invention relates to a magnetic induction waveguide communication device and method for safety monitoring of an underground pipe network. A waveguide relay coil is set between a signal transmission coil and a signal reception coil as a relay node; a signal transmission coil, a waveguide relay coil and a signal reception coil are arranged. Buried in the ground and wound on the underground pipeline to form a magnetic waveguide transmission channel; the traditional electromagnetic wave wireless communication is replaced by the magnetic induction wireless communication, which is used for the safety monitoring of the pipeline network in the underground environment, which improves the reliability of information transmission; the use of the magnetic induction waveguide medium The relay method reduces the information propagation path loss, extends the communication distance, and realizes stable communication at a distance of 300m; the relay device is composed of a closed resonant coil, which does not require power supply and signal processing, which can reduce the energy consumption of the communication system; the communication transceiver coils share one The magnetic induction waveguide transmission channel can realize half-duplex communication, which is convenient for bidirectional transmission of information.

Description

technical field [0001] The invention belongs to the technical field of underground wireless communication, and relates to a magnetic induction waveguide communication device and method for underground pipe network safety monitoring Background technique [0002] Pipeline transportation is related to the development of the national economy and public safety. It has the advantages of large transportation volume, not restricted by climate and other factors on the ground, continuous operation and low cost. In recent years, with the increase in the deployment of various pipelines and the increase in the age of pipelines, due to environmental corrosion and man-made damage, problems such as aging, deformation, and damage of pipeline network facilities have become increasingly serious, threatening national public security and people's property safety. Therefore, the daily maintenance and safety monitoring of the underground pipe network is very important. With the continuous develop...

Problems solved by technology

However, traditional wireless sensor networks mostly use electromagnetic wave wireless communication technology. In the underground environment where the pipe network is located, the electromagnetic wave communication path loss is high, the channel is unstable, and the communication distance is short, so it is impossible to establish an effective communication network.
