Optical fiber slope dam displacement settlement monitoring system

Abstract

The invention discloses an optical fiber slope dam displacement settlement monitoring system which comprises an optical fiber osmotic pressure sensor, an optical fiber displacement sensor, an optical fiber grid settlement sensor, an optical fiber water level sensor and a demodulator, wherein the optical fiber osmotic pressure sensor, the optical fiber displacement sensor, the optical fiber grid settlement sensor and the optical fiber water level sensor are connected with the demodulator through optical fiber; light emitted from a laser in the demodulator is transmitted to different sensors through optical cables; optical signals with information amount to be measured can be reflected back from the sensors; information to be measured is demodulated after the optical signals reach the demodulator to be displayed on a screen; the optical fiber osmotic pressure sensor is used for detecting information of a phreatic line; the optical fiber displacement sensor is used for detecting displacement information of a slope dam body; the optical fiber grid settlement sensor is used for detecting settlement information of the slope dam body; the optical fiber water level sensor is used for detecting the water level information of the slope dam body.

Description

technical field [0001] The invention relates to the field of mines, in particular to an optical fiber slope dam displacement and settlement monitoring system. Background technique [0002] In my country's mine field, safety and benefit are eternal topics. With the rapid development of science and technology, more and more new technologies and products are applied to my country's mining enterprises: the labor intensity of workers is reduced, the output and metal yield are increased, costs are reduced, and benefits are increased. These technologies that directly reduce consumption and increase efficiency are welcomed by everyone. At the same time, the safety production of mining enterprises has also been raised to an unprecedented height and has attracted attention. With the country's further strengthening of mine safety rectification, adopting new technologies and methods, strengthening safety monitoring, and eliminating hidden dangers of accidents are becoming the current ...

Problems solved by technology

This method is important, but it can only reflect the appearance of the slope, and cannot carry out continuous microscopic detection of the key inside of the slope; The scene is changing rapidly; in addition, the storage and readability of manual observation and records are poor, and it is impossible to dynamically display the trend of data changes over time in a graphical and analytical manner, and make timely predictions and forecasts
