In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

In the following description, references to the terms "first \ second \ third" are only to distinguish similar objects and do not denote a particular order, but rather the terms "first \ second \ third" are used to interchange specific orders or sequences, where appropriate, to enable embodiments of the invention described herein to be practiced in other than the order shown or described herein.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing embodiments of the invention only and is not intended to be limiting of the invention.

The embodiment of the invention provides an information processing method based on a three-dimensional model of a railway line, and fig. 1 is a flow schematic diagram of the information processing method based on the three-dimensional model of the railway line, which is provided by the embodiment of the invention, and as shown in fig. 1, the method comprises the following steps:

step 101, obtaining design parameters of a track component on a railway line, and generating a three-dimensional model of the railway track based on the design parameters;

step 102, determining identification information of the track member on the railway line according to a preset coding rule;

103, acquiring construction information of the track member, and associating the construction information of the track member and design parameters of the track member into the three-dimensional model through identification information of the track member;

104, constructing an information management platform of the railway track based on the three-dimensional model;

and 105, visualizing the construction information of the track member and the design parameters of the track member according to the identification information of the track member based on the information management platform of the railway track to obtain visualized information, wherein the visualized information is used for visually inquiring the railway track and/or providing information required by construction.

In step 101, design parameters of a rail member may include a plane parameter and a profile parameter of a member point of the rail member.

In an embodiment of the invention, the member points of the rail member may comprise each corner point of a rail plate, a fastener bolt hole and each corner point of a foot included in the railway rail. The plane parameters can comprise information such as mileage values, longitude and latitude distances and the like of the component points. The profile parameters may include information such as elevation, grade, and elevation of the component points.

Here, the latitude and longitude refers to X, Y coordinates of a point in a gaussian plane rectangular coordinate system; the slope refers to the ratio of the vertical height to the horizontal width of the slope; the elevation refers to the distance from a point to a ground level surface along the direction of a plumb line; the super high value is the height difference between two steel rails at the same position of the railway line.

It should be noted that, since the geographic coordinates are spherical coordinates, when the measurement area range is large, the influence of the curvature of the earth cannot be ignored when establishing the plane coordinate system. In order to facilitate planning, design and construction of track engineering, the measurement area needs to be projected onto a plane, so that measurement calculation and drawing are more convenient. Thus, by using a gaussian projection, the projection of the central meridian is taken as the ordinate axis x, and the x-axis north is specified as positive; taking the projection of the equator as an abscissa axis y, and defining the y axis to the east as positive; the intersection point of the two axes is used as the coordinate origin, and the plane rectangular coordinate formed by the intersection point is called a Gaussian plane rectangular coordinate system.

In practical application, a three-dimensional model which can be used for design and subsequent processing work is constructed by obtaining design parameters of each corner point of a track slab contained in a railway track and design parameters of corner points of a base contained in the railway track, importing the design parameters into computer three-dimensional modeling software, and based on the design parameters of each member point of a track member.

In some embodiments, the three-dimensional model of the railway track may include, but is not limited to: and (4) building information BIM model of the track.

It should be noted that the BIM model is a "visual" digital building model constructed based on three-dimensional digital design and engineering software, and provides a scientific collaboration platform for simulation and analysis for workers in various engineering project links, such as designers, architects, and the like, so as to design, build, and manage the engineering project through the BIM model.

In other embodiments, the rail members are classified and encoded according to a railway engineering information model classification and encoding standard, and a rail engineering structure tree is established; and generating a three-dimensional model of the railway track according to the design parameters of the track member in a data-driven manner based on the track engineering structure tree.

It should be noted that the classification and coding standard of the railway engineering information model is formulated by the railway BIM alliance of china, and is used for classifying and coding the railway engineering information model so as to realize the exchange and sharing of the whole life cycle information of the railway engineering and promote the application development of the railway engineering information model.

Illustratively, the track members may be divided into rails and connectors, switches and fittings, bridges and fittings, etc. according to the railroad engineering information model classification and coding standards; the codes are 58-021000, 58-022000 and 58-023000 in sequence. Rails and connectors can be further classified into heavy rails, light rails, special-shaped rails and rail connection fittings; encoded in turn as 58-021010, 58-021020, 58-021030, and 58-021040.

In the embodiment of the invention, the track engineering structure tree organizes each track member of the railway line according to a certain hierarchical relationship according to the hierarchical relationship of the classification result of the track members, so that the category of the track members contained in the railway line and the relationship between specific members contained in the track members of the category can be clearly described.

Illustratively, the root node of the rail engineering structure tree is a rail member, and two branch nodes of the rail engineering structure tree can be rails and bridges; the leaf nodes of the branch nodes corresponding to the track comprise steel rails, fasteners, sleepers and the like. The leaf nodes of the branch nodes corresponding to the bridge comprise piers and abutments.

In the embodiment of the invention, the data driving means organizing the acquired data to form information flow, processing the information flow based on the three-dimensional modeling requirement, and extracting detailed data required by the three-dimensional modeling, thereby simulating the three-dimensional model of the railway track.

In actual implementation, a general three-dimensional model of the railway track is constructed through three-dimensional modeling software of a computer, design parameters of the track member are extracted, and the association between the design parameters of the track member and the general three-dimensional model of the railway track is realized, so that the three-dimensional model of the railway track is simulated.

In step 102, the preset encoding rule is determined according to the project information corresponding to the railway line, for example, the project mileage, the offline infrastructure distribution information of the railway track, the track slab encoding, the track member forming encoding rule, and the like, which are not limited herein.

In practical application, all the track members on the railway line are coded according to a preset coding rule to form identification information of the track members. A corresponding one of the track members on the railroad line can be uniquely identified by the identification information.

In step 103, the construction information of the track member may include retest data of an offline foundation structure of the railway track, construction data of a bed plate, pouring data of a self-compacting concrete layer, track slab laying data, steel rail laying and fine adjustment data, and the like.

The foundation plate construction data can comprise identification information of the foundation plate, measurement data of longitude and latitude, elevation and the like of each angular point of the foundation plate and measurement time. The perfusion data of the self-compacting concrete layer may include: identification information and filling time of the self-compacting concrete layer. The track slab lay-up data may include: identification information of the track slab, position measurement data of the fastener bolt hole and position measurement data of each corner point of the track slab. The rail laying and fine tuning data may include: identification information of the steel rail and measurement data of the track geometric state detector.

It should be noted that the track geometric state detector is composed of a measuring trolley composed of a measuring device such as a track gauge and a level, a body prism and an industrial personal computer, a high-precision total station, a wireless communication unit and the like, and is used for detecting the track internal geometric state (such as track gauge, level, track direction, height, normal distortion and the like) and the external geometric state (such as track center line deviation, elevation deviation and the like) of a railway line, and has important significance for the laying of a base plate of the railway track, the laying of a track plate, the fine adjustment of a steel rail and the later maintenance.

In practical application, according to the identification information of the track members in the railway line, the construction information and the design parameters corresponding to the track members are associated with the corresponding track members in the three-dimensional model.

In step 104, the three-dimensional model data of the railway track may be stored in the model database, different types of data of the railway track may be stored and managed through different data tables, identification information of the track members in each table may be defined as a primary key, data association between each table may be achieved through the primary key, and the three-dimensional model data may be managed and analyzed.

In step 105, based on the information management platform, design parameters and construction information of the track member corresponding to the identification information of the track member are acquired, the design parameters and the construction information of the track member are configured and packaged into a visual management object model, and three-dimensional scene data of the design parameters and the construction information of the track member are generated according to the visual management object model.

The three-dimensional scene data can be used for generating virtual scene images, realizing visualization of the data, and performing track construction quality analysis, progress control, early warning and forecasting, report statistics and dynamic design based on the visualized data.

In this way, the design parameters and the construction information of the rail member are visualized by the information management platform based on the railway track by associating the construction information of the rail member and the design parameters of the rail member into the three-dimensional model of the railway track. According to the identification information of the rail member, the design parameters and the construction information of the rail member are matched with the three-dimensional model of the railway track one by one to obtain the visual information of the data associated with the three-dimensional model, so that the visual management of the project data of the railway track is realized.

Optionally, as shown in fig. 2, fig. 2 is a detailed flowchart of step 104 in the corresponding embodiment of fig. 1. The step 104 comprises:

step 1041, acquiring drawing information and processed material information of the railway track, and associating the drawing information and the processed material information into the three-dimensional model based on the identification information of the track member;

1042, carrying out lightweight processing on the three-dimensional model;

and 1043, storing the three-dimensional model subjected to the lightweight processing into a model database, and establishing an information management platform of the railway track based on data in the model database.

In the embodiment of the invention, the drawing information of the railway track can comprise standard drawings and special section drawings corresponding to different sections of the railway track; the process material information may include a number of process materials corresponding to different sections of the railway track and a number of track members included in the railway track.

Here, the standard drawing refers to drawing information on a railway track including only a portion of a conventional track member. The special section drawing refers to drawing information of an area on the railway track where conventional track components cannot be laid, for example, drawing information of a turnout section laid on a railway line.

In practical application, after drawing information and processing material information of the railway track are acquired, identification information of track members included in a section of the railway track corresponding to the drawing information is determined. And analyzing the identification information of the track member, and coding the drawing based on the analyzed identification information and a preset drawing coding rule to obtain the attached code information of the drawing. And associating the drawing to the three-dimensional model according to the attached code information of the drawing.

According to the identification information of the rail members, the number of the rail members in the processing material information is related to a rail member model in the three-dimensional model; and associating the processed material data corresponding to different sections of the railway track in the processed material information to the railway track model of the corresponding section in the three-dimensional model.

In step 1042, a model in a general format can be obtained by analyzing the three-dimensional model; and extracting geometric data of the track member in the model in the universal format. Extracting geometric data of the same type of track members from the geometric data of the track members, analyzing and calculating the geometric data of the same type of track members, and determining a light-weight three-dimensional model.

Here, the model of the common format refers to a model file format containing geometric data and rendering data of each track member in the three-dimensional model, and the common format is a file format that is compatible with most model software and performs data exchange, such as the FBX format.

The geometric data of the track member refers to data capable of describing the geometric shape of the track member; the geometric data comprises the name, the size, the coordinates and other data of a geometric body; for example, the dimensions of the rail member may be length, width, height, longitude and latitude of a rectangular parallelepiped.

The light-weighted three-dimensional model is model data of the three-dimensional model obtained by lightening the three-dimensional model; compared with the original three-dimensional model, the lightweight three-dimensional model greatly reduces the quantity of repeated information in the model, has smaller data volume of the lightweight three-dimensional model, and is more convenient to store and transmit.

The weight reduction process is to reduce the data amount of the three-dimensional model by compressing the three-dimensional geometric data in the three-dimensional model without changing the structural attributes of the model file. The compression of the three-dimensional geometric data does not change other information therein.

On a microscopic level, the light weight processing is the parameterization of a geometric model in the three-dimensional model; for example, the weight of a cylinder is reduced by parameterization by keeping three parameters of center coordinates of the bottom surface of the cylinder, radius and height of the cylinder. From a macroscopic level, the same primitives are combined through a similarity algorithm in the light weight processing, and matrix data are combined for storage, for example, the same cylinders in the three-dimensional model only keep parameters of one cylinder, the other cylinders record a reference relation and a space coordinate, the reference relation and the space coordinate of all the same cylinders deleted in the model are combined to form matrix data, and the matrix data and the parameters of one cylinder are stored, so that the light weight of all the same cylinders in the three-dimensional model can be completed.

In step 1043, storing the data of the three-dimensional model after the weight reduction process into a model database, encoding the data in the model database according to the preset encoding rule, forming a model tree, and constructing the information management platform of the railway track based on the model tree.

Here, the information management platform of the railway track can be used for realizing visualization, quality control, progress control and process management of the railway track.

In some embodiments, the step 1042 includes:

Here, the preset display rule may be determined according to the user's requirement, for example, the three-dimensional model is displayed according to different sections of the railway track.

In an embodiment of the present invention, the lightening of the three-dimensional model may include lightening the three-dimensional model and lightening of design parameters, construction information, drawing information of the railway track, and processing material information of a rail member associated in the three-dimensional model.

In practical applications, the three-dimensional model may be decomposed into a plurality of sub-models corresponding to different segments of the railway track according to the different segments of the railway track; and processing each sub-model data to respectively obtain views with different display accuracies.

Illustratively, the three-dimensional model is divided into a roadbed section sub-model, a bridge sub-model and a tunnel sub-model according to the type of an offline foundation structure of a railway track, and data of each sub-model is compressed to different degrees respectively, so that standard definition, high definition and super definition of each sub-model are obtained, and the three views with different display precisions are obtained.

In other embodiments, the three-dimensional model may be directly stored in a model database, and when a user accesses the three-dimensional model through the information management platform of the railway track, the data of the three-dimensional model is acquired from the model database through simplified display of a view manager according to the display requirement of the user, and data portions of other models which are not required to be displayed temporarily in the data of the three-dimensional model are deleted, so that the occupation of memory by model portions which are not required to be viewed is reduced.

In the embodiment of the present invention, the preset access setting information is used to determine the data to be displayed. For example, if the access setting information is to display only the design parameters of the track component, the data to be displayed may be the mileage value, the longitude and latitude distance, the elevation, and other information of the track component; can be set according to the requirements of users, and the invention is not particularly limited.

In practical application, determining data to be displayed according to preset access setting information; and acquiring corresponding data to be displayed from the design parameters, construction information, drawing information of the railway track and processing material information of the track member associated with the submodel to be displayed, and displaying the information of the track member associated in the specific view according to the specific view of the submodel to be displayed when the submodel is displayed.

Exemplarily, the data to be displayed is determined as the design parameters and the construction information of the track member of the bridge sub-model according to preset access setting information. And acquiring the design parameters and the construction information of the track member from the design parameters, the construction information, the drawing information and the processing material information of the railway track associated with the bridge sub-model. And when the full line view of the bridge submodel is displayed, the drawing information and the processing material information related to the bridge submodel are displayed, and when the view of each track member of the bridge submodel is displayed, the design parameters and the construction information of the track member are displayed.

In other embodiments, the preset access setting information may include access right information of the user and railway line construction phase information.

Correspondingly, the displaying, according to preset access setting information, part or all of the design parameters, construction information, drawing information of the railway track and processing material information of the track member associated with the submodels of the plurality of different views, includes:

In practical application, the access authority information may include a primary authority, a secondary authority, and a tertiary authority; the number of levels of the authority information can be set according to actual requirements. The first-level authority can be the highest-level authority and can correspondingly access design parameters, construction information, drawing information of the railway track and processing material information of all the track components corresponding to the railway line.

The railway line construction stage information may include a constructed complete section, a construction section and a next stage preparation construction section for accessing design parameters, construction information, drawing information and processing material information of the rail track in stages according to actual construction conditions of the railway line.

In actual implementation, after the data part to be displayed is determined according to the access authority information and/or the railway line construction stage information, the data part to be displayed is obtained from the design parameters, construction information, drawing information of the railway track and processing material information of the track member associated with the sub-model and displayed.

Exemplarily, according to the information of the railway line construction stage and the access authority information, the user is determined to be in the first-level authority, and the data of the preparation construction part in the next stage of the tunnel sub-model is requested to be accessed; and acquiring all data of a next-stage preparation construction part from the design parameters, construction information, drawing information and processing material information of the railway track related to the tunnel sub-model, and displaying the data.

In practical application, the drawing information and the processed material quantity information of the railway track are subjected to visual processing to obtain three-dimensional graphic data of the drawing information and the processed material quantity information of the railway track. Integrating three-dimensional graphic data of the drawing information and the processed material quantity information of the railway track into a three-dimensional model according to the track identification information corresponding to the drawing information and the processed material quantity information of the railway track; therefore, a user can check specific railway track drawings, machining material quantity information of track members related to the models and the like by clicking the three-dimensional model in the information management platform.

In practical application, the design parameters and the construction information of the track member are obtained according to the identification information of the track member, the two sets of data are analyzed in real time and compared with the standard specification value of the railway track design, and the quality analysis result of the track member is determined according to the comparison result. And carrying out visualization processing on the quality analysis result of the track member to obtain graphic data of the quality analysis result of the track member. And according to the identification information of the track member, realizing the association of the graphic data of the quality analysis result and the corresponding track member model in the three-dimensional model.

In other embodiments, after the quality analysis result of the track component is determined, the error level of the track component can be determined according to a preset error level division rule and visualization rules with different error levels; and determining a visualization rule corresponding to the error grade according to the error grade of the track member.
