A mountain crack monitoring and early warning system and early warning method

Abstract

The present invention provides a mountain crack monitoring and early warning system, the system includes: insulating wire barrel, resistance wire, metal slide, metal connecting rod, first non-metallic support rod, second non-metallic support rod, first fixed rod, second Two fixed rods, ammeter, angle processor, vertical angle sensor, pillar, horizontal angle sensor, power supply; resistance wire is wound on the insulating wire barrel; one end of the metal connecting rod is connected to the metal sliding piece, and the metal sliding piece is connected to the insulating wire The resistance wire on the barrel is in contact, the first non-metallic support rod connects the other end of the metal connecting rod with the first fixed rod; the second non-metallic support rod connects the end of the insulating wire barrel and the vertical angle sensor, and the pillar connects the vertical angle sensor The sensor is connected with the vertical angle sensor and the horizontal angle sensor, and the bottom of the horizontal angle sensor is connected with the second fixed rod. The monitoring and early warning system of the invention has the advantages of simple and reliable structure, convenient operation and strong sensitivity, and can effectively monitor the real-time changes of displacement and angle of cracks in the mountain body.

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...

AI Technical Summary

Problems solved by technology

Manual data collection cannot realize all-weather and all-terrain observation, cannot issue disaster warning information in time, and cannot obtain a large amount of data in a short period of time; while the use of high-precision instrument monitoring is mostly expensive, complicated to operate, and requires high professional quality of operators, which seriously restricts The popularization and use of disaster early warning system

In view of the actual situation of frequent occurrence of geological disasters in our country, many points and areas, and insufficient professionals, the existing early warning system for mountain crack disasters has not found a suitable balance point in terms of monitoring timeliness, economy, operability, and structural reliability.
