The invention provides a rail transit system based on a sensing network, wherein a temperature sensor and a humidity sensor are used for monitoring the temperature signal and the humidity signal of the rail, the first analysis unit fuses the humidity signal and the temperature signal, and due to the fact that the temperature and the humidity have the corresponding relation, only when the humidity is in a certain temperature range, the toughness of the track can reach a low ebb; the pressure sensor and the vibration sensor are used for monitoring a vibration signal and a pressure signal of a track, the vibration signal and the pressure signal are fused, and the vibration signal becomes small when the pressure value is large, so that the state of the track is difficult to monitor by purely monitoring the vibration signal; finally, correlation exists among the temperature and humidity signals, the pressure signals and the vibration signals, and therefore the third analysis unit is used for fusing the four signal data, and safety monitoring can be better conducted on the track.

    本发明提供一种基于传感网络的轨道交通系统,通过温度传感器和湿度传感器用于监测轨道的温度信号和湿度信号,第一分析单元融合湿度信号和温度信号,因为温度和湿度是存在对应关系的,只有在某一温度范围内时湿度处于某一范围时,轨道的韧性会达到低谷;通过压力传感器和振动传感器用于监测轨道的振动信号和压力信号,在此也将振动信号和压力信号融合,因为在压力值较大时,振动信号也会变小,因此,单纯监测振动信号难以对轨道的状态进行监测;最后温湿度、压力、振动信号之间也存在关联,因此,使用第三分析单元对上述四个信号数据进行融合,更加能够对轨道进行安全监测。
