Development On Local Monitoring Software For DaFoSi Yangtse River Bridge And Its Application

With development of automation and intelligent in bridge safety monitoring, traditional detection method already don't satisfy monitoring request of large bridge long-term. So computer automation monitoring software play a important role in monitoring. Dafosi Yangtse River bridge is one of ten largest bridges, scientists and engineers pay more attention to its safety state. Monitoring it is Significance. Local monitoring software of Dafosi Yangtse River bridge is one of important parts in monitoring system, studying it is necessary.In this dissertation, the importance and necessity of monitoring software for Dafosi Yangtse River bridge are first presented, then the study actuality of software is analyzed.Aim at request of monitoring software, function system is designed, and necessity of main function module and child function module is introduced.As acquiring state information in key position of bridge structure is core of monitoring, so firstly, information acquisition software of all kinds of sensors is studied.For prolonging the life of sensors and instrument, hardware and software about their measure power controlled automatically is designed.On the basis of information acquisition software, multi-method in data acquisition is also designed. But original data can't reflect parameter's variety, so software pretreatment the original data, and save data by SQL Server 2000.In addition, for the convenience of users' remote control , remote controllable module is designed. It make remote user can repair system parameter, execute dynamic remote acquisition, require transfers historical data of local monitoring system,etc.Finally, for proofing application result of monitoring software, debugging of it run in laboratory, then it was applied on Dafosi Yangtse River bridge, data provides reliable proof for Dafosi Yangtse River bridge safety evaluation.
