[0002] Satellite navigation and positioning continuously operating base stations are important spatial information infrastructure and have been widely used in railway engineering construction and operational safety. Establishing and maintaining a unified, high-precision, three-dimensional coordinate benchmark is the prerequisite for the satellite navigation and positioning base station network to achieve networking and service sharing, and is also the foundation for railway engineering construction and operational safety.

[0045] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.
[0046] Please refer to Figure 1 and Figure 2 In order to solve the above technical problems, a first aspect of an embodiment of the present invention provides a method for processing data of a strip network railway reference station, comprising the following steps:
[0047] Step S100, obtaining observation data of several IGS reference stations.
[0048] Step S200, obtaining observation data of several standard reference stations within a preset range around the belt network railway reference station, the standard reference stations include: national stations, provincial stations and China Tectonic Environment Monitoring Network Station (hereinafter referred to as Lutai website). In addition, the standard reference stations may also include: continuously operating ground reference stations that meet the requirements of provincial stations.
[0049] Step S300 , based on the observation data of the IGS reference station and combined with the observation data of the standard reference station, a plurality of railway reference stations are subjected to hierarchical calculation to obtain the spatial coordinate data of each railway reference station.
[0050] The present invention provides a rich data basis for the coordinate calculation of railway reference stations by acquiring observation data from IGS reference stations and standard reference stations such as surrounding national stations and provincial stations; it also adopts a hierarchical solution method to improve the coordinate accuracy, avoid error accumulation, and enhance the reliability of the results. In addition, it can also adapt to different accuracy requirements and complex environments, consider local differences, and better meet the needs of belt network railway projects for high-precision coordinate data. After adding surrounding national reference stations and provincial reference stations, the number of reference points increases, the position distribution is more reasonable, the coordinate difference with the known results is significantly reduced, the system deviation of the coordinate results is well corrected, and the coordinate accuracy of the entire network is also significantly improved.
[0051] Specifically, in step S300, based on the observation data of the IGS reference station and combined with the observation data of the standard reference station, a hierarchical solution is performed on several railway reference stations, including:
[0052] Step S310 , selecting a first preset number of railway reference stations as first-class railway reference stations, and the remaining railway reference stations as second-class railway reference stations.
[0053] This number of stations are selected from a number of railway reference stations as first-level railway reference stations. These selected first-level railway reference stations can usually be determined based on some specific criteria, such as the importance of geographical location, superiority of observation conditions, etc. The remaining railway reference stations are classified as second-level railway reference stations.
[0054] Step S320, based on the observation data of the IGS reference station and the observation data of the standard reference station, coordinate frame joint measurement and solution are performed on the plurality of first-class railway reference stations to obtain spatial coordinate data of the plurality of first-class railway reference stations.
[0055] Obtain observation data from IGS reference stations and standard reference stations (national, provincial and land-based sites). IGS reference stations have high-precision global positioning system observation data, while standard reference stations provide relatively accurate coordinate references at the national or provincial level. Combined with the above-collected data, coordinate frame joint measurement and solution are performed on the first-level railway reference station; the observation data of the first-level railway reference station is integrated and analyzed with the observation data of the IGS reference station and the standard reference station to determine the spatial coordinate data of the first-level railway reference station in a specific coordinate frame. Through precise calculation and adjustment, measurement errors can be eliminated and the accuracy of coordinates can be improved.
[0056] Step S330, based on the spatial coordinate data of a plurality of primary railway reference stations, the spatial coordinate data of the secondary railway reference stations are solved.
[0057] After obtaining the accurate spatial coordinate data of several primary railway reference stations, the spatial coordinate data of the secondary railway reference station are solved based on these data. For example, by measuring the relative position relationship between the secondary railway reference station and the nearby primary railway reference station, the coordinates of the secondary railway reference station are calculated using the known coordinates of the primary railway reference station, and the corresponding error correction is performed to ensure that the coordinate solution results of the secondary railway reference station have high accuracy and reliability.
[0058] Furthermore, the step S310 of selecting a first preset number of railway reference stations includes:
[0059] Step S311, selecting a number of first-level railway reference stations in a linear network or a Y-shaped network.
[0060] The linear network of first-level railway reference stations can better cover different areas along the railway and provide a more even distribution of reference points for subsequent coordinate calculations. These linearly distributed reference stations can be arranged along the direction of the railway to ensure that more accurate coordinate references can be obtained in different sections.
[0061] The first-level railway reference station of the Y-type network can better adapt to this complex line structure and provide more accurate basic data for the coordinate calculation of the railway reference station in the branch and intersection areas. By selecting the first-level railway reference station with such a specific network structure, the accuracy and reliability of the coordinate calculation of the entire railway reference station can be improved, and the needs of railway engineering construction and operation can be better met.
[0062] Furthermore, a plurality of first-class railway reference stations are evenly distributed in a linear network or a Y-shaped network.
[0063] Uniform distribution ensures comprehensive coverage of different locations along the railway. Whether it is a linear network or a Y-shaped network, each area can have effective observations from a first-level railway reference station, making the measurement data richer and more accurate. Uniform distribution can reduce measurement errors caused by sparse reference stations in local areas and improve the overall coordinate measurement accuracy.
[0064] For further information, please refer to Figure 3a and Figure 3b , the step S330 of calculating the spatial coordinate data of the secondary railway reference station based on the spatial coordinate data of the plurality of primary railway reference stations includes:
[0065] Step S331 : dividing a plurality of standard reference stations into a plurality of standard subnets according to preset areas, each standard subnet including a plurality of standard reference stations located in a corresponding preset area.
[0066] Several standard reference stations are divided into several standard subnets according to preset areas. The division of preset areas can be determined based on factors such as geographical scope and railway line segmentation. Each standard subnet contains several standard reference stations located in the corresponding preset area. Such division helps to carry out subsequent coordinate solution more targetedly and improve calculation efficiency and accuracy.
[0067] Step S332, based on the observation data of the IGS reference station and the observation data of several standard reference stations in the standard subnet, coordinate frame joint measurement and solution are performed on several first-level railway reference stations in the standard subnet to obtain the spatial coordinate data of the first-level railway reference stations in the corresponding preset areas.
[0068] The observation data of the IGS reference station and the observation data of several standard reference stations in the standard subnet are used. The IGS reference station provides a high-precision global positioning reference, and the standard reference station provides a relatively accurate coordinate basis in a specific area. For several first-level railway reference stations in the standard subnet, the collected data is combined to perform a joint measurement and solution of the coordinate frame. By integrating data from different sources and considering various measurement errors and influencing factors, the spatial coordinate data of the first-level railway reference station in each preset area is accurately calculated. In this way, the coordinates of the first-level railway reference station can more accurately reflect its position in a specific area.
[0069] Step S333, based on the spatial coordinate data of the primary railway reference station in the corresponding preset area, respectively solve the spatial coordinate data of several secondary railway reference stations in the corresponding preset area.
[0070] Based on the spatial coordinate data of the primary railway reference station obtained in each preset area, the spatial coordinate data of several secondary railway reference stations in the area are solved. Relative positioning and other technologies can be used to measure the relative position relationship between the secondary railway reference station and the primary railway reference station in the same area, and use the known coordinates of the primary railway reference station to infer the coordinates of the secondary railway reference station. In the solution process, special factors such as the terrain and signal propagation in the area need to be considered, and corresponding error corrections need to be made to ensure that the coordinate solution results of the secondary railway reference station are accurate and reliable.
[0071] Further, in step S333, based on the spatial coordinate data of the primary railway reference station in the corresponding preset area, the spatial coordinate data of several secondary railway reference stations in the corresponding preset area are respectively calculated, including:
[0072] Based on the spatial coordinate data of several first-level railway reference stations, the baselines of several first-level railway reference stations are calculated, and the spatial coordinate data of several second-level railway reference stations are solved based on the baselines.
[0073] Based on the spatial coordinate data of several first-level railway reference stations, the baseline between these first-level railway reference stations is calculated. The baseline reflects the relative position relationship between two reference stations and can be calculated by methods such as coordinate difference. The calculated baseline of the first-level railway reference station is used to solve the spatial coordinate data of several second-level railway reference stations in the corresponding preset area. The specific method can be to measure the relative observation value between the second-level railway reference station and the nearby first-level railway reference station, and calculate it in combination with the baseline. For example, differential positioning and other technologies can be used to determine the spatial coordinates of the second-level railway reference station using the known coordinates and baseline of the first-level railway reference station, as well as the observation difference between the second-level railway reference station and the first-level railway reference station. In the solution process, it is necessary to consider the influence of factors such as measurement error and signal propagation, and make corresponding error corrections to improve the accuracy and reliability of the coordinate solution of the second-level railway reference station.
[0074] Further, step S333b, after solving the spatial coordinate data of a plurality of secondary railway reference stations based on the baseline, further includes:
[0075] Step S333c, obtaining the synchronization loop Nrms value of each secondary railway reference station.
[0076] After the spatial coordinate data of several secondary railway reference stations are solved based on the baseline, the synchronization loop Nrms value of each secondary railway reference station is obtained. The Nrms (Normalized Root Mean Square) value is an indicator used to evaluate the quality and accuracy of measurement data. In the railway reference station coordinate solution, the synchronization loop Nrms value can reflect the quality and consistency of the synchronous observation data between the secondary railway reference station and other reference stations.
[0077] Step S333d, if the synchronization loop Nrms value is less than the solution threshold, it indicates that the secondary railway reference station solution result meets the requirements.
[0078] When the Nrms value of the synchronization loop is less than the solution threshold, it indicates that the solution result of the secondary railway reference station meets the requirements. This means that the coordinate solution result of the secondary railway reference station is within the acceptable accuracy range and has good consistency with the observation data of other reference stations.
[0079] Step S333e: If the synchronization loop Nrms value is greater than or equal to the solution threshold, it indicates that the secondary railway reference station solution result does not meet the requirements.
[0080] When the synchronization loop Nrms value is greater than or equal to the solution threshold: it indicates that the solution result of the secondary railway reference station does not meet the requirements. This may be caused by a variety of reasons, such as poor observation data quality, large measurement errors, inaccurate baseline calculations, etc. In this case, it is necessary to check and adjust the coordinate solution process of the secondary railway reference station. It may be necessary to re-acquire observation data, optimize the solution method, or adjust the solution parameters to improve the accuracy and reliability of the solution results until the synchronization loop Nrms value is less than the solution threshold.
[0081] Furthermore, in step S320, based on the observation data of the IGS reference station and the observation data of the standard reference station, a coordinate frame joint measurement and solution is performed on the plurality of first-class railway reference stations to obtain the spatial coordinate data of the plurality of first-class railway reference stations, including:
[0082] Based on the observation data of the IGS reference station and the standard reference station, the baselines of the IGS reference station and the standard reference station are calculated, and the spatial coordinate data of several first-level railway reference stations are solved based on the baselines.
[0083] Based on the observation data of the IGS reference station and the observation data of the standard reference station, the baseline between the IGS reference station and the standard reference station is calculated. The baseline reflects the relative position relationship between the two reference stations and can be calculated by methods such as coordinate difference. The calculated baselines of the IGS reference station and the standard reference station are used to solve the spatial coordinate data of several first-level railway reference stations. The specific method can be to establish a mathematical model to jointly solve the observation relationship between the first-level railway reference station and the IGS reference station and the standard reference station. In the solution process, it is necessary to consider the influence of factors such as measurement error and atmospheric refraction, and make corresponding error corrections to improve the accuracy and reliability of the coordinate solution of the first-level railway reference station.
[0084] Accordingly, please refer to Figure 4 The second aspect of the embodiment of the present invention further provides a belt network railway reference station data processing system, comprising:
