The invention provides a signal system fault analysis method and device based on a knowledge graph, and the method comprises the steps: determining a centralized station corresponding to each train according to the current position of each train operating on a line and the communication range of each centralized station on the line; under the condition that any train has first fault equipment at the current moment, equipment, connected with the first fault equipment, of a centralized station is retrieved from a knowledge graph according to the centralized station corresponding to the train; and under the condition that second fault equipment exists in the retrieved equipment of the centralized station, determining that the first fault equipment and the second fault equipment have an association relationship. According to the method, the train corresponds to the concentration station through the position relation at a certain moment, the time relation is converted into the space distance relation, the troubleshooting complexity is reduced, the troubleshooting time is shortened, and the fault analysis accuracy is improved.

    本发明提供一种基于知识图谱的信号系统故障分析方法及装置,该方法包括:根据线路上运行的每个列车在当前时刻的位置和所述线路上每个集中站的通信范围,确定每个列车对应的集中站;在任一列车在当前时刻存在第一故障设备的情况下,根据所述任一列车对应的集中站从知识图谱中检索与所述第一故障设备连接的所述集中站的设备;在检索出的所述集中站的设备中存在第二故障设备的情况下,确定所述第一故障设备与所述第二故障设备之间具有关联关系。本发明通过某一时刻的列车与集中站通过位置关系对应,将时间关系转为空间距离关系,降低故障排查的复杂度,进而降低了故障排查的时间,提高故障分析的准确性。
