Abstract

The invention discloses an intelligent geologic hazard comprehensive monitoring system and a multi-level forecast analyzing method. The system is a monitoring device which can be assembled and disassembled according to the requirement, and is applicable to outdoor assembly. The system is a shaft after assembly, measures in fixed time and wirelessly transmits information of slope underground depth deformation to a system information analysis control unit form the ground, acquires an image in a monitoring area by continuously scanning in fixed time by a laser scanner, and is provided with a multipoint fixed point ranging laser to carry out accurate range measurement on a selected object. The system and the method take the geologic hazard underground depth deformation and ground surface direct deformation displacement as main monitoring forecast foundation, and divide hazard forecast into four levels, namely a preparing level, a pre-warning level, an early forecast level and a hazard forecast level by combining with assistant parameters and induction factors of physical and chemical field variations, thereby integrally completing the functions of monitoring, analyzing and forecasting on site.

Description

technical field

[0001] The invention belongs to the technical field of physical automatic control, in particular to an intelligent geological disaster comprehensive monitoring system and a multi-level forecasting and analysis method. Background technique

[0002] Geological disaster monitoring is a comprehensive technology that integrates the formation mechanism of geological disasters, monitoring instruments, space-time technology and prediction and forecasting technology. At present, the research and application of monitoring technology methods for geological disasters at home and abroad are mostly carried out around sudden geological disasters such as collapses, landslides, and debris flows.

[0003] Monitoring methods are mainly divided into four categories based on the type of parameters for detection. The first is disaster body deformation monitoring, including monitoring methods that mainly measure displacement and deformation information: such as deep underground de...
