Abstract

The invention provides a mountain crack monitoring and early warning system. The system comprises an insulated wire barrel, a resistance wire, a metal slide sheet, a metal connecting rod, a first non-metal supporting rod, a second non-metallic supporting rod, a first fixing rod, a second fixing rod, a galvanometer, an angle processor, a vertical angle sensor, a support column, a horizontal angle sensor and a power supply. The resistance wire is wound on the insulated wire barrel. One end of the metal connecting rod is connected to the metal slide sheet. The metal slide sheet is contacted withthe resistance wire on the insulated wire barrel. The first non-metal supporting rod is connected to the other end of the metal connecting rod and the first fixing rod. The second non-metallic supporting rod is connected to the end portion of the insulated wire barrel and the vertical angle sensor. The support column is connected to the vertical angle sensor and the horizontal angle sensor. The bottom of the horizontal angle sensor is connected to the second fixing rod. The structure of the monitoring and early warning system is simple and reliable, operation is convenient, sensitivity is high, and a mountain crack displacement and the real-time change of an angle can be effectively monitored.

Description

technical field [0001] The invention relates to a crack monitoring device, in particular to a monitoring and early warning system and early warning method for crack deformation of mountain bodies, and belongs to the field of monitoring and early warning of natural disasters. Background technique [0002] Mountain cracks are one of the causes of landslides, and their consequences seriously threaten the safety of human life and property. Affected by extreme weather in recent years, its hazards have become more prominent. Therefore, it is of great significance to realize all-weather real-time monitoring of mountain crack deformation and to predict and warn possible landslide disasters. [0003] At present, conventional monitoring methods mostly use manual data collection or high-precision instrument monitoring. Manual data collection cannot achieve all-weather and all-terrain observation, cannot issue disaster warning information in time, and cannot obtain a large amount of d...
