Slope structure safety monitoring system and method based on distributed sensing optical cables

Abstract

The invention relates to a slope structure safety monitoring system and method based on distributed sensing optical cables, and belongs to the field of rock-soil body disaster prevention and monitoring. The system comprises an on-site sensor subsystem, a data acquisition and transmission subsystem and a display and control subsystem. The on-site sensor subsystem comprises a distributed sensing optical cable and an anti-slide pile; the data acquisition and transmission subsystem comprises a data acquisition module and a data transmission module, and a communication optical fiber transmits monitoring data to the data acquisition module and sends the current structure safety state to the display control subsystem through the data transmission module. The display control subsystem comprises adatabase server, a Web server, client software, a sound-light alarm and a short message alarm. And the database server receives and stores the data transmitted by the data acquisition and transmissionsubsystem, and the Web server evaluates the structure security state. Automatic acquisition, transmission, storage, processing analysis and comprehensive early warning of monitoring data can be realized, and the system has the capability of realizing real-time monitoring under various weather conditions.

Description

technical field [0001] The invention relates to a slope structure safety monitoring system and method based on distributed sensing optical cables, belonging to the field of rock and soil disaster prevention and monitoring. Background technique [0002] In recent years, the construction of expressways in China, especially in mountainous areas, has developed rapidly, and the proportion of high slopes in the highways is increasing. The current situation of my country's existing road maintenance management is that there are limitations in the standardized management of high slopes. Up to now, there is no precedent and experience for the integrated dynamic monitoring and management of high slope groups in my country. It is mainly based on manual judgment, which has limitations such as strong subjectivity, difficulty in quantification, long cycle, poor effectiveness, and insufficient timeliness. Manual inspection items and inspection reports are mostly stored in paper media, which ...

Problems solved by technology

Due to the wide range of lines and the differences in the professionalism of business personnel, the manual inspection mode has limitations such as strong subjectivity, difficulty in quantification, long periodicity, poor timeliness, and inability to achieve 7×24 hours of uninterrupted monitoring. Due to frequent disasters and many other factors, the geological security situation is worrying, and there is an urgent need for a measure that can monitor the geological situation from time to time, so that the early management personnel can respond in time to ensure safety when abnormal situations occur.
