The invention relates to a BIM-based grating array track monitoring information visualization analysis method and system. The method comprises the following steps: constructing a track construction BIM model on a monitoring platform; field monitoring points and model monitoring points of the BIM model are arranged, state information of the track structure is monitored through fiber grating sensors arranged at the field monitoring points and sent to a fiber grating demodulator, and the fiber grating demodulator receives the monitoring information sent by the fiber grating sensors and demodulates the monitoring information; and the fiber bragg grating demodulator transmits monitoring information of each field monitoring point to the model monitoring points corresponding to the BIM model in real time, reconstructs, operates and maintains the BIM model, and updates model, information and image visualization results in real time. According to the method, a track is dynamically modified according to monitoring information parameterization to construct a BIM model, a full-life-cycle track digital twinborn model is formed, the model and information are utilized to carry out dynamic analysis, disease analysis, structural analysis and the like, and then visual expression of analysis results is achieved.

    本发明涉及一种基于BIM的光栅阵列轨道监测信息可视化分析方法及系统,该方法包括在监测平台上构建轨道建造BIM模型;布置现场监测点和BIM模型的模型监测点,通过现场监测点布置的光纤光栅传感器监测轨道结构的状态信息并发送给光纤光栅解调仪,光纤光栅解调仪接收光纤光栅传感器发送的监测信息,并解调;光纤光栅解调仪将各个现场监测点的监测信息实时传输至BIM模型一一对应的模型监测点,重构运营维护BIM模型,实时更新模型、信息、影像可视化成果。本发明根据监测信息参数化动态修改轨道建造BIM模型,形成全生命周期的轨道数字孪生模型,利用模型、信息开展动力学分析、病害分析、结构分析等,进而实现分析结果的可视化表达。
