The Application Of Bridge Structure Health Monitoring System Based On Hadoop Platform

Generally there are systems of the structure health monitoring in the large bridges atpresent. Due to multi-sensor located in the bridge for continuous acquisition and enormousdata amount transfer for a long time, while the work of analyzing and processing of presentbridge structure health monitoring data mostly proceeds in monitoring center at the bridge sitefield, but bridge site field management agencies rarely equip with professional technical thatcan fully deal with the massive monitoring data, which often face the phenomenon of largeamounts of data that can not receive effective information timely. Cloud computing is a newlyemerging solution that can meet the bridge structure health monitoring of massive dataprocessing and professional computing needs. Cloud computing provide related ability tousers as a way of service, which allows in the situation of users do not understand servicetechnology, without related knowledge and equipment operational capability, which make thesystem more intelligent, reduce the intensity and difficulty of human work through theInternet to obtain needed services.One kind of bridge structure health monitoring system on the basis of the Hadoopplatform is proposed in this paper, which based on the analysis of the bridge healthmonitoring system development situation, also combined with theory development and actualdemand, bridge structure health status assessment system is established, the collection andmonitoring for the bridge structure security feature parameter, function parameter andstructure meet parameter is realized, which make the evaluation system of the bridgelong-term security and the durability further perfect, the science theory reference for thebridge maintenance and management is also provided.The bridge structure health monitoring system is overall designed in this article, bridgecondition assessment problem is studied by DER&U, and the system design of the bridge health assessment system is completed, which has carried out in Hadoop open source cloudcomputing platform. The comprehensive evaluation and the long-term monitoring of thebridge health are realized. The Hadoop eclipse is selected to developing cloud evaluationsystem in this topic, storing and accessing monitoring data through distributed file systemHDFS, calculating the environmental parameters of the bridge used the Map/Reducealgorithm, managing and organizing the state of the bridge health situation by Hbasedistributed database. At last, the XML technology is used to seal data, which realized the visitand control of bridge structure health monitoring system by the C/S pattern, furthermore, thesecurity evaluation of Wei River Bridge is tested. The test result shows that this system isfeasible.
