The invention discloses a railway turnout health state real-time monitoring method, and belongs to the technical field of rail transit. According to the method, stress sensors are installed on a straight stock rail and a curved stock rail to collect the dynamic response of a steel rail when a train passes through, acoustic emission sensors and vibration sensors are installed on a straight point rail, a curved point rail, a straight point rail and a curved point rail, and the acoustic emission sensors are responsible for sensing high-frequency vibration signals generated by steel rail cracks; the vibration sensor is responsible for detecting the state of a wheel rail, data detected by all the sensors are sent to the monitoring host, and the monitoring host is used for calculating train running data and sending the train running data to the cloud for sharing and storage. The system has very good real-time performance, all calculation work can be completed within one minute after the train passes, the result is sent to the cloud, and the working efficiency of related departments is improved.
本发明公开了一种铁路道岔健康状态实时监测方法,属于轨道交通技术领域。该方法通过在直基本轨和曲基本轨上安装应力传感器,采集列车通过时钢轨的动力响应,并在直尖轨、曲尖轨、直心轨和曲尖轨上安装声发射传感器和振动传感器,声发射传感器负责感知由钢轨裂纹产生的高频振动信号,振动传感器负责检测轮轨状态,通过各个传感器检测到的数据发送至监测主机上,利用监测主机计算出列车行驶数据,并将列车行驶数据发送至云端共享和保存。本发明具有非常好的实时性,列车通过后的1分钟内就可以完成所有的计算工作,并将结果发送到云端,提高相关部门的工作效率。
