Railway disaster-preventive three-dimensional monitoring and alarming system

Abstract

A stereoscopic railway disaster prevention monitoring system used for dangerous rock and falling rock along a railway, a signal processing system, and a monitoring and alarming system. A stereoscopic railway disaster prevention monitoring and alarming system comprises: a stereoscopic railway disaster prevention monitoring system, a signal processing system connected to the stereoscopic railway disaster prevention monitoring system, and an alarming system connected to the signal processing system. In a case in which the signal processing system determines that a protective net (10) has a danger and/or reaches a danger level and vibration is generated and/or a vibratory magnitude reaches a danger level, an alarm signal and/or intelligence information is sent in one or more manners.

Description

technical field [0001] The invention relates to the technical fields of optical fiber sensing, signal processing, industrial informatization, protection and monitoring of dangerous rockfall and rockfall. Specifically, through the fusion of protection net monitoring technology and collapse rockfall monitoring technology, three-dimensional monitoring and alarm of dangerous rockfall is carried out, which is suitable for Safety monitoring of dangerous rockfall along the railway. Background technique [0002] Rockfall is one of the three natural disasters (landslides, debris flows, and landslides) in mountainous areas in my country. Rockfall disasters often occur in steep slope areas with exposed rock mass, fold fractures, and severe weathering. In mountainous areas, landslides and rockfalls occur from time to time, causing minor damage to railways and vehicles, or disrupting roads and causing heavy losses to railway transportation. Rockfall disasters have seriously threatened t...

AI Technical Summary

Problems solved by technology

At present, there are deficiencies in both active and passive prevention and control technologies. Once falling rocks jump over or break through the passive protection net and enter the railway boundary, it will cause serious harm to the normal operation of the line;

[0006] (2) Incomplete monitoring locations and defects in monitoring schemes, etc., resulting in serious system omissions and false alarms;

[0007] (3) It is difficult to determine the forecasting model and alarm triggering conditions;

[0008] (4) Separate monitoring and alarming of protective nets or separate alarm monitoring of landslides and rockfalls, some monitoring equipment is expensive and cannot be used in large quantities
