Safety monitoring method for cross-railway bridge
The invention discloses a safety monitoring method for a cross-railway bridge. The method comprises the following steps: anti-throwing net deformation monitoring, foreign matter invasion radar monitoring and video monitoring; a stress monitoring grating optical fiber vibration sensor is laid on an anti-throwing net on the inner side of a cross-railway bridge to monitor stress deformation state ofthe anti-throwing net in real time; high-precision laser radars are installed in the middles of the two sides of a cross-railway bridge respectively to monitor the oreign matter invasion information in real time, high-definition cameras are installed at the two ends of the anti-throwing net, and when stress deformation of the anti-throwing net is monitored, anti-throwing net video monitoring information is called; high-definition cameras are also installed on the two sides of a railway crossing the two ends of a railroad bridge, and when foreign matter invasion is monitored, rail video monitoring information is called. According to the method, a linkage monitoring mechanism is adopted, so that the three monitoring methods can be used for independent monitoring and linkage monitoring, foreign matter invasion detection is accurate and efficient, and false alarm reporting can be reduced.
本发明公开了一种用于跨铁路桥的安全监测方法。该方法包括防抛网形变监测，异物入侵雷达监测和视频监测，在跨铁路桥梁内侧防抛网上敷设应力监测光栅光纤振动传感器，对防抛网应力形变状态进行实时监测，在跨铁路桥梁两侧的中间分别安装高精度激光雷达，对异物侵入信息进行实时监测，在防抛网两端安装高清摄像机，当监测到防抛网有应力形变时，则调用防抛网视频监控信息，在跨铁路桥梁两端的铁路两旁也安装高清摄像机，当监测到异物入侵时，则调用轨道视频监控信息。该方法采用了联动监控机制，使得上述三种监控方法既可以独立监测又可以联动监测，并且具有对异物入侵检测准确高效，还有利于减少虚警上报。
