The invention relates to the technical field of tunnel fans, in particular to a tunnel fan state intelligent judgment method and device based on survival analysis. According to the method, operation and maintenance data and various sensor detection and monitoring data are fully utilized, and on the basis of fully analyzing the data, the model is established for the fault time, so that the state of the tunnel fan is judged. Compared with an existing method, the scheme has higher universality and convenience, and can be suitable for distinguishing the working states of the fans of the railway tunnel and the highway tunnel at the same time; the system can present the state of each tunnel fan in real time, gives an alarm in time, and has obvious application value. 本发明涉及隧道风机技术领域，特别是一种基于生存分析的隧道风机状态智能判别方法及设备。本发明充分利用了运维数据和多种传感器检测监测数据，在对数据充分分析的基础上，分别针对故障时间建立模型，实现对隧道风机状态的判别。相较于现有方法，本发明所述方案具有更强的普适性和便捷性，能同时适用于铁路隧道与公路隧道的风机工作状态判别；能够实时呈现各隧道风机状态，并及时告警，具有明显的应用价值。
