Abstract

The invention relates to a rail transit safety monitoring system and method, and the system comprises a sensing network which comprises a fiber bragg grating vibration sensing optical cable, a fiber bragg grating strain sensing optical cable and a fiber bragg grating array temperature sensing optical cable which are arranged on a rail transit engineering structure; the data processing center is used for processing monitoring signals of the fiber bragg grating vibration sensing optical cable, the fiber bragg grating strain sensing optical cable and the fiber bragg grating array temperature sensing optical cable and determining sensing data; and the intelligent operation and maintenance service platform is used for performing intelligent analysis according to the sensing data and monitoring the engineering structure and the train state of the rail transit based on an intelligent analysis result. The defect that traditional rail transit engineering structure operation period health monitoring is mainly based on strain parameter evaluation is changed, and the accuracy and reliability of structure health state evaluation are improved through combined monitoring of multiple parameters such as strain, vibration and temperature.

Description

technical field [0001] The technical field of traffic safety monitoring of the present invention relates in particular to a system and method for rail traffic safety monitoring. Background technique [0002] In recent years, the urban rail transit system has developed rapidly. As a major structural project and an important part of the lifeline of urban traffic, the healthy operation of the urban rail transit engineering structure is crucial to the normal operation of the city. However, rail transit engineering structures are gradually damaged with operation, especially under the influence of complex load conditions such as temperature, trains, foundation deformation, and external intrusion, and diseases may occur at any time, affecting traffic safety. Structural diseases of rail transit projects occur frequently and suddenly, causing many safety accidents. [0003] Aiming at the health and safety of rail transit infrastructure, research on sensing detection theory and monit...
