[0070] Embodiment 3.1: A rail comprehensive detection method uses a time calibration method to calibrate all detection data, and then integrates the data at the same position according to the vehicle layout, so as to facilitate the analysis and judgment of the comprehensive status of the line.

[0071] Step P1: During the detection data collection process, the collected data is calibrated with time information, and all detection parameters are calibrated with the time information.

[0072] Step P2: Due to the installation position relationship on the vehicle body, the line parameters detected by the detection device and the flaw detection device at the same time will have a certain distance.

A maintenance room (1012) and a testing room (1013), wherein the testing room (1013) is provided with a comprehensive testing table and an electrical cabinet, and the driver's room (1010) is provided with an air conditioner (102), wherein the comprehensive testing table includes a display, and the display is also connected to an operating device, and the display is used to display the operation display interface of each testing system, and the operating device includes a mouse and a keyboard; the display is installed on a rotatable and adjustable bracket, and each bracket is equipped with two displays; the maintenance room is provided with a water tank and a maintenance operating table; the testing room is also provided with a printer and a file cabinet; The rail comprehensive detection method is to calibrate all the detection data by time calibration, and then integrate the data at the same position according to the layout of the whole vehicle, so as to facilitate the analysis and judgment of the comprehensive status of the line: Step P1: During the detection data collection process, the collected data is calibrated with time information, and all detection parameters are calibrated with the time information; Step P2: Due to the installation position relationship on the vehicle body, the line parameters detected by the detection device and the flaw detection device at the same time will have a certain distance. The flaw detection parameters of the detection position of the detection device at a certain time point are obtained through calculation combined with the line operation displacement calculation; Step P3: Conduct a comprehensive analysis of the line conditions after comprehensive data collation and analysis; Step P4: After the calculation software completes the compilation and arrangement of the detection data, the comprehensive status of the line rail is analyzed and output to the display interface, providing a basis for line maintenance for line management; The data comprehensive arrangement in step P3 includes the geometric state of the track, the surface of the rail and the comprehensive working conditions of the internal damage of the rail.
