Embodiment 1

[0030] image 3 A schematic structural diagram of the line detection system in Embodiment 1 of the present application is shown.

[0031] As shown in the figure, the line detection system includes: a relative position measurement device 301, and a deviation detection device 302 connected to the relative position measurement device; a first measuring device and a second measuring device arranged at a second detection position of the vehicle;

[0032] The relative position measurement device is used to measure the relative position between the second detection position of the vehicle and the first detection position of the vehicle through the cooperation of the first measurement device and the second measurement device; the first detection position work before the second detection position;

[0033] The deviation detection device is used to detect whether there is a deviation in the second detection position according to the relative position between the second detection posit...

Embodiment 2

[0060] Based on the same inventive concept, the embodiment of the present application provides a line detection method. The principle of solving technical problems of this method is similar to that of a line detection system, and the repetitions will not be repeated here.

[0061] Figure 4 It shows a schematic flowchart of implementing the line detection method in Embodiment 2 of the present application.

[0062] As shown in the figure, the line detection method includes:

[0063] Step 401, measuring the relative position between the second detection position of the vehicle and the first detection position of the vehicle; the first detection position works before the second detection position;

[0064] Step 402 : Detect whether there is a deviation in the second detection position according to the relative position between the second detection position of the vehicle and the first detection position of the vehicle and the preset reference of the second detection position.

Embodiment 3

[0079] In order to facilitate the implementation of the present application, the embodiment of the present application takes the vertical elevation detection of railway lines as a specific example for description.

[0080] Figure 5 It shows a schematic flowchart of the implementation of the method for detecting the vertical height of the railway line in the third embodiment of the present application.

[0081] As shown in the figure, the method for detecting the vertical height of the railway line includes:

[0082] Step 501, shooting an image of the first marker at the predetermined height at the second detection position at the preset height of the first detection position;

[0083] In one embodiment, the first marker is a first scale bar, and the zero scale height of the scale mark on the first scale bar is the predetermined height, and one side of the zero scale is positive and the other side is negative. scale.

[0084] Step 502: Perform image recognition, analysis an...

Abstract

The invention discloses a line detection system, a line detection method and a tamping wagon. The system comprises a relative position measurement device and a deviation detection device connected with the relative position measurement device; the relative position measuring device comprises a first measuring device arranged at a first detection position of a vehicle and a second measuring devicearranged at a second detection position of the vehicle; the relative position between the second detection position of the vehicle and the first detection position of the vehicle through the cooperation of the first measuring device and the second measuring device, operation at the first detection is earlier than operation at the second detection position; and the deviation detection device detects whether the second detection position deviates or not according to the relative position between the second detection position of the vehicle and the first detection position of the vehicle and a preset reference of the second detection position. By adopting the technical schemes of the invention, the line deviation of the second detection position where operation is not performed is calculatedby taking the first detection position where operation has been performed as the reference point, so that a detection result is accurate.

Description

technical field [0001] The application relates to large-scale maintenance machinery technology, in particular, to a line detection system and detection method, and a tamping vehicle. Background technique [0002] Existing tamping car line vertical height detection device is to be installed in figure 1 The three detection trolleys B, C, and D shown are composed of measuring rods on the left and right sides, two steel strings and two height sensors. Such as figure 1 As shown, a steel string is tensioned at the top of the measuring rods R and F erected on the detection trolleys B and D, and the M point of the string passes through the height sensor touch rod on the C trolley, so that the relative measurement of the C point can be detected. The high and low deviation value from the BD baseline. [0003] Such as figure 2 As shown, the existing tamping car line direction deviation detection device is generally composed of four points D, C, B, A installed on the tamping car, w...
