Description
Technical field
The utility model relates to the information management system in a kind of Architectural Equipment field, particularly a kind of prestressed component Life cycle information management system that is applicable to bridge.
Background technology
In recent years, the construction of the increasing, particularly high-grade highway that drops into along with China infrastructure drops into and strengthens, and Bridges in Our Country quantity sharply increases.Wherein the part bridge is owing to the effect or the design and construction defective of external environment, and bridge is performance degradation during one's term of military service, even the major accident that inefficacy is subsided occurs, and has not only caused enormous economic loss, also brings bad social influence.Therefore problems such as long-term service level of bridge and Life Cycle Management more cause the concern of various circles of society.
Bridge structural health monitoring is actually the monitoring of (comprising temperature, stress, displacement, kinematic behavior etc.) of a multiparameter.The monitoring plurality of large bridge structure adopts method local and whole fusion detection; Most bridges have been installed the displacement meter of seismograph, wind gage, accelerometer, Global Positioning System (GPS), measurement girder edge dislocation in the existing report, the thermometer sensor is taken into account in the displacement of measuring tuned mass damper, utilize multi-source heat transfer agent integration technology monitoring bridge environment for use situation and bridge changes under this situation characteristic parameter.Such monitoring technology of analysis-by-synthesis is not difficult to find that existing monitoring technology more paid attention to the ambient conditions that bridge is on active service, and pays close attention to less to the variation characteristic of structure self.To above situation, Chinese scholars has also proposed dissimilar structural change monitoring modes.Fibre Optical Sensor is one of present adopted main mode, and this sensing mode can effectively be monitored prestress distribution and member dynamic property.University Of Chongqing, Harbin Institute of Technology, how tame colleges and universities of Beijing Jiaotong University are engaged in the research of this aspect, in engineerings such as Shanghai Xu Pu bridge, Humen Bridge and Jiangyin Yangtze Bridge, have laid the Fibre Optical Sensor of some at present.Retrieval through to the prior art document is found; Chinese patent ZL200710169093.0; Patent name: mobile bridge structure detects and attending device, and this patented technology has only been paid close attention to the health detection situation of bridge structure, does not pay close attention to the Life cycle information management of bridge.
The utility model content
The utility model provides a kind of prestressed component Life cycle information management system to the deficiency of above-mentioned prior art, make its can the design of tracking and monitoring bridge member, make, in the overall process of labour, and the relevant information in its overall process managed.
The technical scheme that realizes above-mentioned purpose is:
A kind of prestress monitoring system comprises one first RF identification sensor, is installed on the steel bridge; One second RF identification sensor is installed on the prestress bridge; One first defective sensor and one second defective sensor are installed on the prestress bridge, and the said first defective sensor and the second defective sensor are connected in the said second RF identification sensor; One environmental working condition sensor is installed on the bridge pier; One information management system server, communication link are connected to the said first RF identification sensor, the second RF identification sensor, the first defective sensor, the second defective sensor and environmental working condition sensor.
The utility model can carry out effective recognition to steel bridge and prestress bridge through the first RF identification sensor and the second RF identification sensor; Through the first defective sensor and the second defective sensor, can the structural change of prestress bridge be detected; Can monitor installation environment operating mode in the bridge installation process through the environmental working condition sensor; The information management system server can receive the signal that sends of each sensor through wireless mode, can manage the Life cycle information of prestress bridge through the information management system server.The utility model can be through the characteristic of comprehensive different phase, and process links such as reverse optimization design, manufacturing are for the bridge quality control provides new design considerations and method.The utility model in Bridge Design, work progress be pre-buried architectural feature monitoring sensor and in the bridge installation process installation environment operating mode sensor, through this category information of radio frequency chip synthetical collection; Bridge military service situation is regularly gathered and uploaded to exploitation highway/bridge information cruising inspection system; Through design precast beam Life cycle information management system, the Life cycle information of effectively managing precast beam.Through collection, can abundanter decision-making foundation be provided for prestressed component designs with manufacturing, thereby be that follow-up production optimization provides the basis the prestressed component application message.
Compared with prior art; The utlity model has following beneficial effect is: this is through the integrated of wireless Internet of Things infotech, bridge structure monitoring technology, network information management technology etc. and exploitation; Can the tracking and monitoring bridge member design, make, in the labour overall process, can explore bridge life management assessment system.
