Abstract

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.

Key words: railway bridges, distributed system, embedded system, state warning, Daqin Railway
