Gps Displacement And Deflection Monitoring Bridge Health Monitoring System

The bridge health monitoring system collects and deals with the date about bridge construct damage by the global positioning system to give us where the damage is and how about the damage.The paper is about the monitoring displacement and flexibility.In the foundation of collecting the research of the domestic and foreign bridges health monitoring system, the paper analyses the present situation, the development tendency and the front technology of the domestic and foreign bridges health monitoring, and proves the necessity and the feasibility of developing the GPS bridge health monitoring system. According to the bridge structure and the environment of the bridge health monitoring system, proposes the bridge GPS monitor plan, determines the composition of the system structure; According to the difference mathematical model of the carrier phase, derivates the double difference baseline vector solution to calculate the process in detail, and carries on the establishment of the simulation software using matlab; designs the OEM board periphery expander; After experimenting, through the contrast to the data processing result of the simulation software and evaluating software , confirms this system's feasibility, and proposes the further improvement methods and the measure.
