Compared with the prior art, the intelligent electricity channel deformation monitoring system and method have the advantages of intelligent monitoring, precise positioning, lower cost and the like.

Description

technical field [0001] The invention relates to the field of disaster prevention and reduction in geotechnical engineering, in particular to an intelligent power pipe deformation monitoring system. Background technique [0002] With the continuous deepening of my country's urbanization process, the city's demand for electricity is also growing exponentially. However, overhead lines have various disadvantages: small transmission capacity, large footprint, hindering city appearance, weak ability to resist natural disasters, frequent failures, and easy to cause safety accidents. Therefore, the use of power pipes and other methods to make power transmission facilities land has become the main way to solve the problem of urban power supply. At present, every city in the country has a huge power pipeline transmission network. As one of the city's lifeline projects, the power supply affects the whole body. How to take effective measures to sense the existing power grid to ensure ...

[0005] Optical fiber monitoring technology is a new type of monitoring technology that monitors changes in physical characteristic parameters of light waves such as intensity (power), wavelength, frequency, phase, and polarization state during optical fiber transmission with the development of optical fiber communication technology in recent years. It has the advantages of high precision, high sensitivity, anti-electromagnetic interference, good electrical insulation, strong durability, suitable for long-term monitoring, plastic geometry, strong adaptability, small transmission loss, and long-distance detection. The optical fiber in the distributed optical fiber monitoring technology based on the principle of Liouin scattering is not only a transmission medium, but also a sensor, so it can achieve a fully distributed and seamless monitoring of the structure. However, at present, this technology has not been applied to the structural deformation of power pipes. self-awareness work
