Graded early warning system for monitoring dumping collapse by means of inductosyn

Abstract

The invention discloses a graded early warning system for monitoring dumping collapse by means of an inductosyn. The graded early warning system includes a plurality of linear inductive synchronizers, a plurality of rotary inductive synchronizers, a first wireless transmission module, a second wireless transmission module, a monitoring processing host, an early warning analysis system and an early warning issuing system that are successively in wireless connection. The linear inductive synchronizers and the rotary induction synchronizers not only can accurately monitor the variation of crack width in the process of dangerous rock mass collapse, but also can effectively measure the rotation angle of the dangerous rock mass during the dumping process, the monitoring data is sent to the monitoring processing host via the wireless transmission modules, and the monitoring processing host summarizes and organizes the monitoring data to form graphical data. The graded early warning system can visually reflect the deformation process of the collapsed dangerous rock mass, establishes the temporal and spatial relationship of dangerous rock mass dumping deformation, thereby accurately monitoring the dumping trend of the dangerous rock mass, and timely issuing the corresponding early warning information.

Description

technical field [0001] The invention relates to the field of geological disaster monitoring and early warning, in particular to a hierarchical early warning system for monitoring toppling-type collapses by using an induction synchronizer. Background technique [0002] With the development of the economy, the construction of roads and railways, and the expansion of the scope of urban life and production, human life and property safety are increasingly threatened by dangerous rock mass collapses. However, the most effective way to reduce the losses caused by dangerous rock mass collapses The most important measure is to monitor and warn the deformation of dangerous rock mass collapse. [0003] There is a long history of research on the monitoring of dangerous rock mass collapse, and there are many monitoring methods. The most traditional method is to use a ruler to directly measure the width change of the tensile cracks at the trailing edge of the dangerous rock mass collapse....

AI Technical Summary

Problems solved by technology

[0003] There is a long history of research on the monitoring of dangerous rock mass collapse, and there are many monitoring methods. The most traditional method is to use a ruler to directly measure the width change of the tensile cracks at the trailing edge of the dangerous rock mass collapse. Although this method is intuitive and simple, the measurement accuracy Poor, cannot record width changes in real time, and has certain dangers in the measurement process

[0004] With the development of science and technology, some new technologies such as acoustic emission monitoring system, ultrasonic displacement sensor, and three-dimensional laser scanning technology have been applied to the monitoring of collapsed dangerous rock mass. The measurement accuracy is low, in addition, the cost is high, and it cannot be well promoted and used in actual engineering
