The invention relates to a railway bridge section track disease monitoring method and system based on combination of a grating array and video monitoring, and the method comprises the steps: arranging a fiber grating array optical cable on a track structure, carrying out the real-time collection of track state monitoring data, and transmitting the data to a background server through a fiber grating demodulator; a plurality of video cameras are installed along the whole track at intervals, and the video cameras send shot video monitoring data to a background server through video data receiving equipment; the background server judges whether the track state monitoring data collected by each measuring point is abnormal or not, if the track state monitoring data collected by a certain measuring point is abnormal, it is indicated that the possibility that the track structure has diseases exists in the area corresponding to the measuring point, and then the video monitoring data of the area is called for display; and a supervisor is assisted to identify the specific type of the disease. According to the invention, real-time monitoring and type identification of the railway track structure disease condition are realized, and the disease type is visually reflected through a video.

    本发明涉及一种基于光栅阵列结合视频监测的铁路桥梁地段轨道病害监测方法及系统,该方法包括:在轨道结构上布置光纤光栅阵列光缆对轨道状态监测数据进行实时采集,并经光纤光栅解调仪传递给后台服务器;沿轨道全线间隔安装若干视频摄像头,视频摄像头将拍摄的视频监测数据经视频数据接收设备发送至后台服务器;后台服务器判断各个测点采集的轨道状态监测数据是否出现异常,若某个测点采集的轨道状态监测数据出现异常,则表明该测点对应的区域存在轨道结构已出现病害的可能,然后调取该区域的视频监测数据进行显示,辅助监管人员对病害的具体类型进行识别。本发明实现了对铁路轨道结构病害情况的实时监测和类型识别,通过视频直观反映病害类型。
