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...

Embodiment Construction

[0034] In order to make the purpose, structure and advantages of the present invention clearer, preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] figure 1 It is an overall architecture diagram of a three-dimensional monitoring and alarm system for railway disaster prevention according to an embodiment of the present invention. figure 1 The three-dimensional monitoring and alarm system for railway disaster prevention shown in the figure is respectively combined with the "air" monitoring of the protective net and the "land" monitoring of the rails to form a three-dimensional monitoring and alarm for landslides.

[0036] In order to achieve the above object, the three-dimensional monitoring and alarm system for railway disaster prevention according to the present invention should be composed of three parts at least: the three-dimensional monitoring system for railway disaster prevention...
