Stress strain all-weather monitoring spherical device based on high stress condition

Abstract

The invention discloses a stress strain all-weather monitoring spherical device based on a high stress condition. A communication line is connected with a nine-axis attitude indicator chip; the nine-axis attitude indicator chip is positioned inside a sphere; the communication line is positioned inside a stainless steel tube; the communication line is connected with a data acquisition main board; adata signal conversion module, a data analysis and processing module, a data acquisition module and a data storage module are arranged in the data acquisition main board; a semiarc and an equatorialplane supporting axial surface are arranged at the exterior of a core sphere; a stress strain gage is arranged in a position where the semiarc is connected with an upper and lower chord supporting axial surface; a stress strain gage is arranged in a position where the semiarc is connected with the equatorial plane supporting axial surface; the communication line connected with a position between the stress strain gage and the data acquisition module penetrates through a data wire guide and enters the interior of the core sphere. The stress strain all-weather monitoring spherical device can beapplied to big data and cloud computing technical platforms, and provides effective data acquisition and analysis technical support for the future geological disaster monitoring work.

Description

technical field [0001] The invention relates to a stress-strain all-weather monitoring spherical device based on large stress conditions, which is specifically used in areas with large ground stress or projects with a sharp increase in stress after underground engineering excavation, combined with cloud computing platform computing capabilities and big data analysis and Prediction ability, to achieve the role of monitoring and forecasting and early warning, belongs to the field of geological disaster monitoring and rock mechanics stability analysis. Background technique [0002] With the continuous improvement of science and technology in our country, the demand for mineral resources has increased, the development of deep resources and the use of natural caving methods, as well as the development of other underground projects, such as tunnels, subways, etc. Many large-scale mines in China still use the open field method when mining in deep areas, which causes a sharp increas...

AI Technical Summary

Problems solved by technology

Many large-scale mines in China still use the open field method when mining in deep areas, which causes a sharp increase in ground stress and a significant increase in rockbursts; natural caving mining completely changes the ground response field, and the monitoring of future geological disasters is completely blank. ; In the development of underground projects, passing through areas with high ground stress, especially railway and highway tunnel projects, there is no relevant monitoring technology to achieve early warnin
