Study On The Key Technologies Of The Bridge Health Wireless Monitoring System

Bridge health wireless monitoring system can be received all kinds of information about bridge construct damage from sensor net. According to these message the system can give us the bridge health state and working information, and also can give us where are the damage and how about the damage. This project will develop followed parts: surveying unit (GPS surveying,vibration surveying,temperature surveying and so on),data acquisition unit,wireless correspondence unit and database management system . The bridge health wireless monitoring system will help for the research and development of damage automatic detection and diagnosis.In the foundation of the preliminary work ,the paper only involves three parts of the bridge health wireless monitoring system: the DSP bridge health wireless data acquisition sub-unit,the GPRS wireless cprrespondence sub-unit and the manage database sub-unit based on the Visual Basic 6.0 and Access 2000. Make out a electronic circuit board including the data acquisition uint and the wireless correspondence unit. It has the function :acquisition of kinds of data,simple data processing,data transmission and so on .Realize the request of the bridge health wireless monitoring system and provide the basis for other monitoring of other large-scale buildings. The man-machine contact surface of the bridge health wireless monitoring system is friendly, achieve the management of the bridge information.
