Hongfeng Lake Bridge Health Monitoring System Data Acquisition System

The construction and maintaining of huge bridges is one of the key factors of national fundamental instruments construction, each huge bridge is the milestone of the development of civilization, and the technique of bridge health monitoring reflects a nation's bridge construction and management level.Through the monitoring and evaluation for the state of the bridge structure, the bridge healthy monitoring system will send out pre-alert signal when the bride is under special climate, special traffic condition and the serious exceptions of running condition, and it analyses and evaluates the bridge life and supplies scientific evidence for the maintaining and management policy. Last for the moment, the long-time bridge examination mainly depends on the periodical manual examination, but this measure has some limitations such as untimely, inaccurate, partial and hard work intension.Associated with the project, the research on monitoring of bridge structure is investigated in this paper. The program of the whole monitoring system is put forward. Based on the objective and functional requirement of establishing the Bridge Health Monitoring System, the load characteristic of specified bridge style is analyzed and the monitoring program is formed by step in the paper.Aiming at the actuality of the bridge examination, this paper brings forward a measure that uses the specialties of FBGS, such as real-time, long-time and precision, to solve the problems which the manual examination measures cannot solve well, and researches the bridge healthy monitoring system with FBGTS and FBGSS. In general, the bridge healthy monitoring system is composed of the data collection system and the structure healthy state and security system. The data collection system is the base of the whole monitoring system.
