| Abstract: | Abstract： This paper proposed and developed an efficient and reliable distributed wireless intelligent bridge monitoring system for the monitoring of common span and wild distribution bridges. This system is consisted of a sensor, an acquisition node, a gathering controller and a central sever. It presented a new real time early warning method and the parameters based on both the monitoring data and existing test specification for railway bridge to realize a graded early warning of bridge running state.The proposed monitoring and pre warning system is verified in the real time monitoring of Daqin Railway bridge. |
