Referring next to fig. 5, 6 and 7, fig. 5 is a schematic structural diagram of a wheel set 1 and a vehicle body 2 in an embodiment of the rail inspection vehicle of the present disclosure, fig. 6 is a schematic structural diagram of a support wheel 20 in an embodiment of the rail inspection vehicle of the present disclosure, and fig. 7 is a schematic structural diagram of a suspension wheel 21 in an embodiment of the rail inspection vehicle of the present disclosure. As shown in fig. 5, the wheel set 1 includes a support wheel 20 and a suspension wheel 21 with adjustable height, as shown in fig. 6, the support wheel 20 includes a first bracket 200 and a first wheel 201, the first bracket 200 is fixed to a side surface of the front end of the vehicle body 2, and a rotating shaft of the first wheel 201 is rotatably connected to the first bracket 200; as shown in fig. 7, the suspension wheel 21 includes a second bracket 210, a suspension spring 211 and a second wheel 212, the second bracket 210 is fixed to a side surface of the rear end of the vehicle body 2, one end of the suspension spring 211 is fixedly connected to the second bracket 210, and the other end is perpendicularly connected to a rotating shaft of the second wheel 212, so that the suspension spring 211 is compressed between the second bracket 210 and the rotating shaft of the wheel.
In the embodiment, the suspension spring 211 is compressed between the second wheel 212 and the second bracket 210, so that the suspension wheel 21 has adaptive adjusting force, and the pretightening force of the suspension spring 211 can improve the buffering capacity of the vehicle body 2 and the adhesion degree of the second wheel 212 and the rail. In addition, the first wheel 201 of the support wheel 20 is rigidly connected with the first bracket 200, so that the rigidity of the rail inspection vehicle can be ensured. Therefore, the rail patrol vehicle can give consideration to both rigidity and self-adaptive adjustment capability, so that the rail patrol vehicle can be more stable when running along the rail.
Then returning to fig. 5, a position sensor 30 is further arranged on the vehicle body 2, and the position sensor 30 is in communication connection with the controller 3; the controller 3 is also configured to determine the position information of the rail inspecting vehicle at the present time based on the signal of the position sensor 30 and record the position information of the rail inspecting vehicle at various times.
As an example, an encoder may be used as the position sensor 30, and the encoder may record the rotation angle of the wheelset 1, so that the travel distance of the rail inspection vehicle can be derived, and the position information of the rail inspection vehicle can be determined. For another example, a GPS (Global Positioning System) module may be provided on the vehicle body 2, and the position of the track inspection vehicle may be represented by GPS coordinates of the vehicle body 2.
The controller 3 determines the position information of the rail inspecting vehicle at the current time based on the signal of the position sensor 30, and records the position information of the rail inspecting vehicle at each time. The operator can transfer the moving record of the rail patrol car so as to backtrack the operation process of the rail patrol car.
Further, the controller 3 is also configured to: acquiring a time stamp of the image with the defect in response to identifying the image with the defect; acquiring the position information of the track inspection vehicle at the time indicated by the timestamp; and outputting the image with the defect and the position information of the rail patrol car at the time indicated by the time stamp.

In some optional implementation manners of the present embodiment, an attitude sensor is further disposed on the vehicle body 2, and the attitude sensor is in communication connection with the controller 3; the controller 3 is further configured to: and determining the attitude information of the track inspection vehicle at the current moment based on the signal of the attitude sensor, and determining the track inclination angle at the current moment based on the attitude information of the track inspection vehicle.
In practice, there may be a phenomenon that the track is inclined due to the damaged roadbed, and this phenomenon may not be reflected in the image, so in this implementation, the attitude sensor (for example, a gyroscope) is used to collect the attitude signal of the track inspection vehicle, and then the controller 3 determines the attitude information of the track inspection vehicle at the current time according to the attitude signal, and derives the track inclination angle at the current time from the attitude information of the track inspection vehicle. A worker can determine whether the track is inclined through the track inclination angle, so that the defect that the image information does not describe the track posture is overcome, the dimensionality for detecting the track defect is expanded, and the accuracy of track detection is further improved.
Further, the control is further configured to: responding to the track inclination angle being larger than a preset threshold value, and determining a timestamp of the track inclination angle; acquiring the position information of the track inspection vehicle at the time indicated by the timestamp; and outputting the track inclination angle and the position information of the track patrol vehicle at the time indicated by the timestamp.
In this embodiment, the operator may preset a threshold according to practical experience, and if the track inclination angle is greater than the threshold, it indicates that the track has a defect of over-tilting. The controller 3 may determine whether the track has a defect of over-tilting by comparing the track inclination angle with the threshold value.
And the time stamp of the track inclination angle represents the acquisition time of the attitude information corresponding to the track inclination angle. When the controller 3 detects that the track inclination angle is larger than the threshold value, the position information of the track inspection vehicle at the moment can be determined through the timestamp of the track inclination angle, so that the position corresponding to the track inclination angle can be determined, the position of the track defect can be more accurately positioned by a worker, and the intelligent degree of track inspection operation is improved.
