The real-time detection module 103 comprises a plurality of sensors installed on the side surfaces of urban rails, and the sensors can detect wheel-rail vibration data, wheel-rail deformation data, wheel-rail abrasion data and the like. The sensor is qualitatively connected with the processor, and the positioning data module 102 and the first data uploading module 104 are both electrically connected with the processor. Real-time detection data obtained by the detection of the sensor is transmitted to the processor. The positioning data module 102 is configured to position the real-time detection data collected by the sensor, and bind the real-time detection data with the positioning data. After the real-time detection data are bound with the positioning data, the real-time detection data obtained by detecting each position of the rail are bound with the position information of the position.

The location determining module 205 is configured to select a station closest to the acquisition point of the early warning real-time detection data according to the positioning data bound to the early warning real-time detection data. Since the real-time detection data is bound to the positioning data, the location determining module 205 can select a station closest to the early warning real-time detection data acquisition point according to the positioning data bound to the early warning real-time detection data, and then the communication transmitting module 206 is configured to transmit a field detection request to the station closest to the early warning real-time detection data acquisition point.
