Description
Technical field
The invention belongs to civil engineering, earthquake engineering technical field, and in particular to when being applied to " the Internet+" to one kind
Generation, the bearing that Fibre Optical Sensor is carried out based on bearing strain and can be acted on to bridge normal operation and disaster under two kinds of operating modes should
Change carries out monitor in real time and makes the Intelligent optical fiber inhaul cable damping support saddle system of risky decision making.
Background technology
Nearly ten years, for understanding aging to bridge structure, functional deterioration, and also to avoid bridge structure from occurring
Sudden destruction, bridge health monitoring field have obtained swift and violent development, and which is mainly by the various importances for structure
Energy index carries out precision monitor to reach the purpose of evaluation structure safety.On the whole, bridge health monitoring development situation is gratifying,
But many problems are still faced with actual concrete operations, including：Number of sensors is big, difficult arrangement, or even many
Up to hundreds of individual, mounting arrangements complex procedures；Monitoring system data wire is numerous, and data line interface work is complicated；Measure result
Data are huge, and daily data processing work is loaded down with trivial details, general maintenance staff's None- identified data result, need to be equipped with professional people
Member；After monitoring is completed every time, monitoring system needs removal, causes repetition and waste of resource etc..In view of when front axle beam is strong
Health monitoring there is disadvantages described above, therefore it is necessary current bridge health monitoring system is optimized, reduce monitoring range,
And by monitoring intelligent, normalization.
We recognize that bridge pad is the crucial structure that stress is transmitted between upper and lower part structure as whole bridge structure
Part, the quality of its running status are directly connected to the safety of whole bridge structure, if the center of gravity of bridge monitoring is placed on whole bridge
The power transmission core of the superstructure and substructure of girder construction --- on bearing, and realized to bearing just by install sensor
Monitoring under normal service condition or disaster operative condition, the means transmitted using real-time radio, Bridge Management ＆ Maintenance personnel pass through again
Client receives data, draws to whether bearing operation conditions normally judges substantially and make corresponding early warning.It is this to supervise
Survey focuses on the scheme of intelligent bearing just into when previous very good selection.
But current intelligent bearing or the bearing in monitoring system are to carry out secondary research and development based on common bearing mostly,
And common bearing cannot usually carry out acting in disaster（Such as earthquake）Under stress measurement, especially to shearing measure；
Secondly, for monitoring result data can not carry out response analysises the very first time and draw risk evaluation result, even if there occurs
Risk also cannot early warning in time facilitate staff to take follow-up action.Therefore, called in current country energetically and build " the Internet
+ ", when the novel information epoch of " cloud process ", in order to vibration absorption and isolation support is applied to bridge health monitoring, antidetonation preferably
In taking precautions against natural calamities, the present invention carries out following process for above-mentioned deficiency：1）The present invention is adopted and is subtracted based on the smart stay cable of Fibre Optical Sensor
Shake bearing, which not only can realize the bearing load-bearing situation to bearing bridge structure under normal operation situation, and early warning bridge surpasses
The occurrence of load, can be acting in disaster（Earthquake or other disasters）Come interim, obtained by monitoring Cable power in bearing
Support shearing force is obtained, and earthquake response suffered by structure is determined such that it is able to pass through to calculate, it is convenient to shake axle casing state rapid evaluation and repair
Multiple, i.e., smart stay cable shock mount can meet the demand of above two working condition simultaneously；2）Passed using fiber grating strain
The transmission of sensor is fast, the features such as signal is good, will monitor data obtained by bearing by wireless using fiber Bragg grating strain sensor
The mode of transmitting is sent to the Internet high in the clouds, realizes the networking transmission of data, such that it is able to data to be delivered to monitoring in real time
In person's handss；3）Research and develop the risky decision making high in the clouds managing and control system based on bearing strain monitoring under bridge normal operation and disaster effect
Software or mobile phone A PP client, its operation principle are to make fast to bearing strain data based on reliability and vulnerability analysis
The reaction of speed draws risk evaluation result, due to the reduction of monitoring data, such that it is able to bridge pad pull-up cable force is measured
Data processor simplifies, and client can inquire about the current operation state of bridge structure at any time in client, once when bridge is met
To overload or even the situation of serious disasters and accidents, risky decision making high in the clouds managing and control system can be run through and check bearing traffic-operating period
Risky decision making is made, and is adopted remedial measures in the very first time.
The content of the invention
It is an object of the invention to provide a kind of monitoring device is more succinct, monitoring purpose more targetedly, at data transfer
Reason is in hgher efficiency, and risky decision making efficiency faster, can preferably be applied to the Intelligent optical fiber inhaul cable damping support saddle in " the Internet+" epoch
System.
To reach object above, the solution that the present invention is adopted is：By smart stay cable shock mount, data collecting instrument,
Wireless data transmitter, the Internet high in the clouds and under bridge normal operation and disaster effect, the risk of strain monitoring is determined based on bearing
Plan high in the clouds managing and control system client is combined, and forms a brand-new Intelligent optical fiber inhaul cable damping support saddle system.Its working mechanism is：
Smart stay cable shock mount with fiber Bragg grating strain sensor is installed, by data acquisition instrument and without line number on bridge
The Internet high in the clouds is transferred data to according to emitter, last client is by logging in risky decision making high in the clouds managing and control system client to knot
Structure realtime running state is consulted, and the risky decision making high in the clouds managing and control system client is former based on reliability and vulnerability analysis
Reason is estimated to make corresponding early warning to bridge real-time status monitoring data.Additionally, the present invention uses smart stay cable subtracting
Shake bearing, this bearing drag-line do not stress in normal operating condition at ordinary times, but when bearing is under disaster operative condition（As
Shake is acted on）, after support shearing force exceedes certain limit, bearing starts to change Morphological Transitions for sliding support, and drag-line gradually can be received
Power, while seismic force is reduced, drag-line limits the over-large displacement of bearing, the generation of restrainer disaster.Therefore, it is of the invention
System not only can realize bearing under normal operation situation, the overload of the vertical strain early warning bridge structure by monitoring bearing
Situation, can be acting in disaster（Earthquake or other disasters）Come interim, cut by monitoring Cable power acquisition bearing in bearing
Power so that it is determined that earthquake response suffered by structure, convenient shake axle casing state rapid evaluation and reparation, the i.e. present invention can be while
Act in normal operation and disaster and normally running under two kinds of working conditions.Therefore, the best advantage is that can pass through
The strain of monitoring bearing completes to act on the monitoring of two kinds of operating modes to bridge normal operation and disaster and make risky decision making in time.
