A Scenic Mountain Monitoring System Based on Optical Fiber Sensing

Abstract

The invention discloses a scenic spot mountain monitoring system based on fiber sensing. The system comprises a vibration monitoring unit, a data acquisition unit, an onsite alarm unit and a control center unit, wherein the vibration monitoring unit comprises a plurality of monitoring mechanisms, the monitoring mechanism comprises a plurality of fiber grating sensors successively connected through fibers, the bottom edge of a mountain is uniformly provided with a plurality of broadband light sources, the top end of the mountain is provided with the data acquisition unit, the monitoring mechanisms are laid on the surface of the mountain, one end of each monitoring mechanism is connected with the broadband light sources, and the other ends of the monitoring mechanisms are connected with the data acquisition unit. According to the invention, such disasters as mountain land slides, rockfalls and the like can be monitored in an omni-directional mode, prompts can be given to tourists at a disaster region or downstream positions of the region, measures can be taken in advance for such disasters as the rockfalls and the like, damage caused by the mountain disasters to equipment can be reduced, it is ensured that monitoring can be continued even in case of the disasters, and data is continuously provided for changing conditions of the mountain.

Description

technical field [0001] The invention relates to the technical field of mountain disaster monitoring, in particular to a scenic mountain monitoring system based on optical fiber sensing. Background technique [0002] Mountain disasters include many types, such as floods, landslides, falling rocks, forest fires, etc., which cause huge losses to human production and life, but human beings are closely related to mountains, and mountain disasters cannot be far away. Monitor and alarm to reduce property damage and casualties. Especially for the mountains of tourist attractions, most of the mountain disasters faced are mudslides, landslides and rockfalls, while mountain torrents and forest fires are not common, so the monitoring of mudslides, landslides and rockfalls is the focus of mountain disaster monitoring in tourist areas . [0003] Debris flow refers to a special torrent carrying a large amount of sediment and stones due to landslides caused by heavy rain, snowstorm or oth...

AI Technical Summary

Problems solved by technology

This invention can monitor mountain disasters in scenic spots, but the structure is complex, wiring is difficult and the monitoring accuracy is low

Moreover, the system device is easily damaged when it encounters a mountain disaster, and it cannot monitor the follow-up. It also makes the reconstruction investment after each disaster is large, and it is not suitable for popularization.
