To provide a track state diagnostic system capable of indicating a portion to be preferentially maintained and prompting the maintenance and replacement of a track before the track is broken after detecting a sign of the breakage of the track in advance.SOLUTION: A track state diagnostic system includes: a sensor data receiving unit 11 for receiving sensor data generated by a sensor which is mounted on a vehicle traveling on a track; a damage detection unit 12 for detecting the damage of the track from the sensor data; a track database 2 in which stress information including stress concentration range information which is positional information of a range where stress applied to the track is concentrated is recorded; a positional information receiving unit 13 for receiving damaged position information indicating a position of the damage detected by the damage detection unit; and a data collating unit 14 for collating the stress concentration range information recorded in the track database with the damaged position information received by the positional information receiving unit and outputting a damage detection result including the damaged position information when the position indicated by the damaged position information is included in the range indicated by the stress concentration range information.SELECTED DRAWING: Figure 1

    【課題】軌道の破断の予兆を事前に検知した上で、優先的に保守すべき箇所を示すことができ、軌道が破断する前に軌道の保守及び交換を促すことができる軌道状態診断システムを提供する。【解決手段】軌道を走行する車両に搭載されたセンサにて生成されるセンサデータを受信するセンサデータ受信部11と、センサデータから軌道の損傷を検知する損傷検知部12と、軌道にかかる応力が集中する範囲の位置情報である応力集中範囲情報を含む応力情報が記録された軌道データべ―ス2と、損傷検知部が検知した損傷の位置を示す損傷位置情報を受信する位置情報受信部13と、軌道データベースが記録する応力集中範囲情報と、位置情報受信部が受信する損傷位置情報とを照合し、損傷位置情報が示す位置が、応力集中範囲情報が示す範囲に含まれる場合に、損傷位置情報を含む損傷検知結果を出力するデータ照合部14と、を備える。【選択図】図1
