The invention discloses a multi-disease comprehensive monitoring method and device for a railway turnout and a medium. The method comprises the steps that global dynamic response variables and local dynamic response variables of a plurality of structural components of the railway turnout are obtained; inputting the global dynamic response variable into a physical-data dual-drive model for analysis to obtain a reference health index; fusing the local dynamic response variables, generating an actual health index corresponding to the reference health index, and performing difference quantitative evaluation according to the reference health index and the actual health index to obtain an evaluation result; calculating and allocating weights for the evaluation results to obtain weight values of the evaluation results; combining the evaluation result with the weight value to obtain a comprehensive diagnosis result; data under the simulated damage condition are obtained by changing physical model parameters, and iterative traceability is carried out in combination with a comprehensive diagnosis result. Information support can be provided for scientific maintenance and targeted damage treatment of the turnout, and the situation that the health state of the railway turnout is further deteriorated due to existence and expansion of the damage is avoided.

    本申请公开一种铁路道岔的多病害综合监测方法、设备及介质,包括:获取铁路道岔的若干结构部件的全局动态响应变量和局部动态响应变量;将全局动态响应变量输入到物理‑数据双驱动模型中进行分析,得到基准健康指标;融合局部动态响应变量,生成基准健康指标对应的实际健康指标,并根据基准健康指标和实际健康指标进行差异性量化评估,得到评估结果;为各项评估结果计算和分配权重,得到评估结果的权重值;结合评估结果与权重值,得到综合诊断结果;通过改变物理模型参数获取模拟损伤情况下的数据,并结合综合诊断结果进行迭代溯源。可为道岔的科学维护和损伤靶向治理提供信息支撑,避免铁路道岔健康状态因为损伤的存在和扩展进一步恶化。
