摘要：

摘要：  针对铁路活载作用下冲击剧烈、环境恶劣、量大面广等特性，研究面向常用跨度铁路桥梁监测的分布式无线监测系统，开发了嵌入式双核数字信号处理器（DSP）智能采集处理终端，构建了以智能终端为基础的铁路桥梁运行状态实时监测系统，并基于单体梁跨监测数据统计分析和既有规范形成参量的多级束界，实现实时分级预警预报，在大秦线桥梁实时监测中应用效果良好.

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
