The invention discloses a long-distance passive sensing rail transit health monitoring system and method, and the system comprises a third analysis module which obtains the corresponding comprehensive deformation quantity of a rail in a historical database when the rail breaks down. The comprehensive deformation quantity of the track to be detected is equal to the sum of the static deformation value of the track to be detected and the dynamic deformation value of the track, and analyzing the relation between the track fault probability and the comprehensive deformation quantity of the track. The invention relates to the technical field of rail transit, and the method comprehensively considers the static deformation quantity of a rail, the dynamic deformation quantity of the rail, the operation duration of the rail and the fault probability of the rail, and quantifies the relation between the operation duration corresponding to different sensors and the fault probability of the rail. The time for overhauling the track to be detected is accurately predicted, and the supervisor of the track to be detected is pre-warned in advance, so that the effective supervision of the health state of the track traffic is realized.

    本发明公开了一种长距离无源感知的轨道交通健康监测系统及方法,所述系统包括第三分析模块,所述第三分析模块获取历史数据库中轨道发生故障时对应的轨道综合形变量,所述待测轨道综合形变量等于待测轨道静态形变值与轨道动态形变值之和,分析轨道故障概率与轨道综合形变量之间的关系。本发明涉及轨道交通技术领域,本发明从轨道的静态形变量、轨道动态形变量、轨道运行时长及轨道故障概率这几个方面进行综合考虑,对不同传感器对应的运行时长与轨道故障概率之间的关系进行量化,准确预测出对待测轨道进行检修的时间,并提前对待测轨道监管员进行预警,实现了对轨道交通健康状态的有效监管。
