Description
Technical field
The invention belongs to civil engineering, earthquake engineering technical field, be specifically related to one and be applicable to " the Internet+" epoch, carry out Fibre Optical Sensor based on bearing strain and can the bearing under bridge normal operation and two kinds of operating modes of disaster effect be strained carrying out monitor in real time and making the Intelligent optical fiber inhaul cable damping support saddle system of risky decision making.
Background technology
Nearly ten years, for bridge structure is aging, functional deterioration understanding, and also to avoid bridge structure that sudden destruction occurs, bridge health monitoring field obtains swift and violent development, and it carries out precision monitor to reach the purpose of evaluation structure safety mainly by the various important performance indexes for structure.On the whole, bridge health monitoring development situation is gratifying, but is still faced with many problems in actual concrete operations, including:Number of sensors is big, difficult arrangement, even up to hundreds of, mounting arrangements complex procedures；Monitoring system data line is numerous, data line interface work complexity；Recording result data huge, daily data processing work is loaded down with trivial details, general maintenance staff's None-identified data result, it is necessary to be equipped with professional；After having monitored, monitoring system needs removal every time, repetition and waste causing resource etc..In view of current bridge health monitoring exists disadvantages described above, therefore necessary current bridge health monitoring system is optimized, reduces monitoring range, and by monitoring intelligent, normalization.
We recognize that bridge pad is upper as whole bridge structure, the key member of stress is transmitted between substructure, the quality of its running status is directly connected to the safety of whole bridge structure, if the center of gravity of bridge monitoring being placed on the superstructure of whole bridge structure and the power transmission core bearing of substructure, and realize bearing monitoring under normal service condition or disaster operative condition by installing sensor, adopt the hands section of real-time radio transmission, Bridge Management & Maintenance personnel accept data again through client, draw whether bearing operation conditions substantially judges and make corresponding early warning normally.This scheme that Monitoring Focus is placed on intelligence bearing has just become when previous very good selection.
But the bearing in current intelligent bearing or monitoring system is based on common bearing mostly carries out secondary research and development, and common bearing is usually the stress that cannot be carried out under disaster effect (such as earthquake) and measures, and especially shearing is measured；Secondly, analysis can not be reacted the very first time for monitoring result data and draw risk evaluation result, even if there occurs that risk also early warning in time cannot facilitate staff to take follow-up action.Therefore, construction " the Internet+" is called energetically at current national, when the novel information epoch of " cloud process ", in order to better vibration absorption and isolation support be applied to bridge health monitoring, in Seismic Resistance And Disaster Reduction, the present invention is directed to above-mentioned deficiency and carry out following process: 1) present invention adopts based on the smart stay cable shock mount of Fibre Optical Sensor, it is possible not only to realize bearing bearing load-bearing situation of bridge structure under normal operation situation, the generation of early warning bridge overload condition, can also come interim in disaster effect (earthquake or other disasters), support shearing force is obtained by monitoring Cable power in bearing, such that it is able to determine earthquake response suffered by structure by calculating, convenient shake axle casing state rapid evaluation and reparation, namely smart stay cable shock mount can meet the demand of above two working condition simultaneously；2) transmission utilizing fiber Bragg grating strain sensor is fast, the features such as signal is good, the data utilizing fiber Bragg grating strain sensor monitoring bearing gained are sent to high in the clouds, the Internet by the mode of wireless transmit, it is achieved the networking transmission of data, such that it is able to data be delivered in real time in supervisor's hands；3) the risky decision making high in the clouds managing and control system software based on bearing strain monitoring under bridge normal operation and disaster effect or mobile phone A PP client are researched and developed, its operation principle is based on reliability and vulnerability analysis and bearing strain data is made rapidly reaction draws risk evaluation result, owing to monitoring the minimizing of data, such that it is able to bridge pad to be pulled up cable force Measurement and Data Processing program simplification, client can inquire about, in client, the operation state that bridge structure is current at any time, once when bridge runs into the situation of overload or even serious disasters and accidents, risky decision making high in the clouds managing and control system can be run through and check that bearing traffic-operating period makes risky decision making, and adopt remedial measures in the very first time.
