[0003] Comprehensive inspection trains conduct comprehensive inspections of high-speed rail tracks, contact networks, communication signals, etc. on a monthly basis, and the operation and maintenance units conduct on-site review and rectification based on the inspection results.

[0023] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0024] The inventors found that the reasons for changes in parameters such as the contact network conduction height and pull-out value are not simply due to changes in the contact network itself. Changes in the track geometry parameters of the lower part of the vehicle will also cause changes in the contact network parameters. Therefore, when analyzing the contact network data, it is necessary to consider not only the influencing factors of the contact network itself, but also the influencing factors of track geometry changes, especially long-wave band data above 42m, that is, to conduct correlation analysis of track geometry and contact network dynamic detection data.

[0025] Mileage data is the unique label for each data point in the detection process. The efficiency of both data analysis and on-site review and inspection depends on the accuracy of the mileage. Therefore, the key factor in the correlation analysis of track geometry and contact network data is to ensure that the detection mileage of the two types of data is the same.

[0026] Based on this, an embodiment of the present invention proposes a contact network detection mileage correction method.

[0027] Figure 1 The contact network detection mileage correction method in the embodiment of the present invention is as follows: Figure 1 As shown, the method includes:

[0028] Step 101, obtaining comprehensive inspection mileage data collected by comprehensive equipment of a comprehensive inspection train;

[0029] Step 102, obtaining corrected track detection mileage data according to the comprehensive detection mileage data;

[0030] Step 103, obtaining the corrected contact network inspection mileage data according to the first distance between the track geometry inspection equipment and the integrated system in the integrated inspection train, the second distance between the contact network inspection equipment and the integrated system, and the corrected track inspection mileage data.

[0031] In an embodiment of the present invention, after obtaining the comprehensive inspection mileage data collected by the comprehensive equipment of the comprehensive inspection train, the corrected track inspection mileage data is first calculated, and then the first distance between the track geometry inspection equipment and the comprehensive system and the second distance between the contact network inspection equipment and the comprehensive system are comprehensively considered, thereby obtaining the corrected contact network inspection mileage data with high accuracy.

[0032] The inspection mileage of track geometry and contact network is derived from the comprehensive inspection mileage data of the comprehensive system on the comprehensive inspection train. All disciplines involved in dynamic inspection (track geometry inspection equipment, contact network inspection equipment) have unified and accurate time and mileage information, which is the premise and basis for comprehensive analysis of line infrastructure inspection data. The comprehensive inspection time and space synchronization technology is one of the key technologies to solve the problem of accurate mileage positioning on the comprehensive inspection train and provide unified real-time mileage, time synchronization and other basic information for various disciplines. The link between the inspection vehicle and the site is the mileage information given during the inspection process. However, due to errors such as interference, wheel diameter, and GPS accuracy, there is a mileage difference between the inspection vehicle mileage and the actual mileage position on site, ranging from a few meters to tens of meters. In addition, the track geometry inspection equipment and contact network inspection equipment are distributed in different carriages. Figure 2 This is a schematic diagram of transmitting mileage information in different carriages in an embodiment of the present invention. Due to the length of the carriages, there is a certain difference in the length of the distance between different professional detection equipment and the comprehensive system. The difference may be different for different models of comprehensive detection trains.

[0033] Depend on Figure 2 It can be seen that the original mileage of track geometry detection and contact network detection are both derived from the mileage synchronization server of the integrated system. However, due to the reasons of the integrated detection train itself and the distribution of professional detection equipment, there are certain differences in the professional mileage data of the track and contact network. However, since this difference is fixed for the same detection train, the mileage correction can be achieved by calibrating the track geometry mileage detection data and transferring it to the contact network mileage.

[0034] Figure 3 The schematic diagram of the contact network detection mileage correction method in the embodiment of the present invention is as follows: based on the comprehensive mileage, the track and the contact network are added with the phase generated by the vehicle body between the track and the contact network and the mileage synchronization server, i.e., oD, to obtain the mileage of this profession:

[0035] D 轨道原始 +oD 轨道 =M 综合 (1)

[0036] D 接触网原始 +oD 接触网 =M 综合 (2)

[0037] D 轨道原始 and D接触网原始 To detect mileage data for tracks and contact lines;

[0038] oD 轨道 is the first distance; oD 接触网 is the second distance;

[0039] M 综合 It is a comprehensive test mileage data.

[0040] In step 101, the comprehensive inspection mileage data collected by the comprehensive equipment of the comprehensive inspection train is obtained, that is, M 综合 .

[0041] In step 102, corrected track detection mileage data is obtained according to the comprehensive detection mileage data;

[0042] In one embodiment, obtaining corrected track detection mileage data according to the comprehensive detection mileage data includes:

[0043] Formula (1) is used to obtain track inspection mileage data based on the first distance and comprehensive inspection mileage data of the track geometry inspection equipment and the comprehensive system in the comprehensive inspection train;

[0044] The track detection mileage data is corrected to obtain corrected track detection mileage data.

[0045] In one embodiment, the track detection mileage data is corrected using the following formula to obtain the corrected track detection mileage data:

[0046] D 轨道校正 =D 轨道原始 -ε 轨道 (3)

[0047] Among them, D 轨道校正 D is the corrected track detection mileage data; 轨道原始 is the track detection mileage data; 轨道 It is the correction factor. The correction factors are different for different lines and different mileage sections.

[0048] ε 轨道 Express the difference between the original track detection mileage data and the corrected track detection mileage data, ε in different mileage intervals 轨道 Values ​​are different and are generated by automated mileage correction technology.

[0049] In step 103, the corrected contact network inspection mileage data is obtained based on the first distance between the track geometry inspection equipment and the integrated system in the integrated inspection train, the second distance between the contact network inspection equipment and the integrated system, and the corrected track inspection mileage data.

[0050] In one embodiment, the following formula is used to obtain the corrected contact network detection mileage data according to the first distance between the track geometry detection equipment and the integrated system in the integrated detection train, the second distance between the contact network detection equipment and the integrated system, and the corrected track detection mileage data, including:

[0051] D 接触网校正 =D 轨道校正 +oD 轨道 -oD 接触网 (4)

[0052] Among them, D 接触网校正 D is the corrected catenary detection mileage data; 轨道校正 oD is the corrected track detection mileage data; 轨道 is the first distance; oD 接触网 is the second distance.

[0053] The derivation process of formula (4) is as follows:

[0054] According to formula (1) and (2), we can get:

[0055] D 轨道校正 +oD 轨道 =M 综合校正 (5)

[0056] D 接触网校正 +oD 接触网 =M 综合校正 (6)

[0057] Among them, M 综合校正 It is the comprehensive detection mileage data after correction.

[0058] Formula (4) can be obtained by combining formula (5) and (6).

[0059] In one embodiment, the method further comprises:

[0060] Based on the correction parameters, the corrected overhead line detection mileage data is regularly revised according to the actual changes in the equipment on the line.

[0061] This is because the vehicle's own conditions, such as wheelset wear and equipment interference, will cause the corrected contact network detection mileage data to have certain changes. It is necessary to use a correction parameter μ and perform regular iterative corrections based on relatively fixed feature points in the line. The formula is as follows:

[0062] D 接触网校正 =D 轨道原始 -ε 轨道 +oD 轨道 -oD 接触网 +μ (7)

In the above process, after obtaining the comprehensive detection mileage data collected by the comprehensive equipment of the comprehensive detection train, the corrected track detection mileage data is first calculated, and then the first distance between the track geometry detection equipment and the comprehensive system, and the second distance between the contact network detection equipment and the comprehensive system are comprehensively considered, and then the corrected contact network detection mileage data is obtained with high accuracy.
