The drawing shows a diagram of a device for collecting data of track objects and set speeds for traffic management systems and safety.

A device for collecting data of track objects and set speeds for auto-driving and safety systems contains a server 1, in the memory of which a single database is recorded, and a personal computer 2 of the automated workstation of the client, in the memory of which are recorded programs that implement the functions of converters, a three-channel comparison unit 3 and data analysis, the inputs of which are connected to the corresponding outputs of the program converters of a personal computer (PC) 2, and its outputs are connected to the corresponding inputs of the system server 1, the first channel of the unit 3 for comparison and analysis of data consists of series-connected module 4 for selecting hauls, module 5 for comparing the starting and ending stations of haul, module 6 for comparing the coordinates of the input traffic lights and input generators of the automatic brake control system and module 7 calculating the coordinates of objects and writing to server memory 1, the second channel of the data comparison and analysis block 3 consists of series-connected module 8 for selecting path segments from the complex database systems of automated decoding of locomotive motion parameters, module 9 for comparing stations belonging to track segments, module 10 for comparing the starting and ending points on the path segment and module 11 for generating object data, calculating coordinates and writing to server memory 1, the third channel of block 3 for comparing and analyzing data consists from series-connected sections 12 of the site selection from the electronic map of the system of the integrated locomotive safety device, module 13 comparing the start and end station of the site, module 14 comparing the path numbers of the plot and module 15 calculating the coordinates of the objects and writing to the server 1 memory, the second inputs of the comparison modules 5, 6, 9, 10, 13 and 14 of all the channels of the data comparison and analysis unit 3 are connected to the corresponding outputs of the server 1, and their second the outputs are connected to the information input of the personal computer 2 information display module 16 of the client workstation, the input / output of the server 1 for requesting and reading information is connected to the corresponding output / input of the personal computer converter programs and 2 automated client workstations.

A device for collecting data of track objects and set speeds for auto-driving and safety systems works as follows.

When using the device, the initial filling of a single database recorded in the memory of server 1 is carried out with information from electronic maps and databases of locomotive systems (KLUB-U, SAUT-TsM, KPD-3), a comparison of the information received among themselves, the exclusion of obviously false information in in accordance with the adopted algorithm, recording filtered information into a single database, transferring data from a single database to client programs at their request for work.

The request to add information (SAUT data), generated using the program that implements the converter functions, is received from the client’s personal computer 2 by the client’s automated workstation (AWS) to server 1, which contains information on hauls for track sections served by the depot in which it is installed AWP. In a single database, a site is defined that corresponds to the imported Saute data, and on this site the objects of the Saute database are created, namely generators and routes, filling out the properties of the objects accordingly. The necessary conditions are the presence in a single database of stations with names that exactly match the names of the starting and ending stations of the haul and the availability of data corresponding to the imported haul of SAUT.

If the conditions for each output, pass, pre-input and input generator in each of the standard stages are met, the objects "Generator Saut" will be added to the database with a point on the path corresponding to the position of the generator and the properties that describe this block section (and the stage for the input generator): the type and number of the generator, the number of the stage, the type of self-locking system, etc.

Module 4 of the selection of sections of the stage at startup (at the command of a user from a personal computer 2 AWP client) turns to each of the SAUT section files in XML format, located in the Data directory in the current directory on the client AWP (2). After reading each file, module 4 analyzes the contents of the XML tags Enter_Station Name (“Name of the starting station”) and Exit_Station Name (“Name of the starting station”) and, together with the coordinates of the input generator extracted from the XML file, transfers information to the initial comparison module 5 and the final station of the stage, and then to the module 6 comparing the coordinates of the input traffic lights and input generators.

To determine the compliance of the SAUT stage with the stage, the database uses the names of the starting and ending station of the stage, which are compared in module 5 for comparing the starting and end station of the stage. Drivers for which it is impossible to establish a one-to-one correspondence are not converted.

Checking the existence of the stage in the database is performed by comparing the points of reference of the stage objects in module 6 comparing the coordinates of the input traffic lights and input generators. To compare the points of the SAUT to the points on the segments in the database during the import of the SAUT data, the ordinate of the input traffic light is referenced (from the condition of the minimum modulus of the difference of the ordinate of the point in the database containing the input traffic light and the point of the input generator of the SAUT). If the difference in ordinates exceeds 50 meters, the binding is considered not reliable, and data on this stage is not imported. The points of the rest (output, passage, pre-entrance) of the SAUT generators are counted from the point of the input generator based on the distances laid down in the SAUT database. The remaining parameters are entered as properties of the object "SAUT Track Generator".

Module 7 receives finally verified data on each haul from module 6, then through a database management system operating on server 1, forms a request to a single database and for each haul adds an object of the type "SAUT Track Generator". The points of the rest (output, passage, pre-entrance) of the SAUT generators are counted from the point of the input generator, based on the distances laid down in the SAUT database, and are also included in a single database. The remaining types of objects are entered as parameters of the SAUT Track Generator objects.

Thus, the SAUT database is imported into the server 1 database in the form of a set of objects of the "SAUT Travel Generator" type and their properties.

Since only those Sauth data can be imported into the database for which it is possible to establish a unique correspondence with the data in a single database, some data can be omitted during the import process, about which the operator will be informed by messages displayed using the information display module 16 on the personal computer monitor 2, of the following form: “No entry point was found in the database, merging cannot be performed” during the program operation. For the data (input haul points), the correspondence of which has been established, the ordinate of the point in the SAUT database, the ordinate of the point in a single database and the distance between them in meters will be displayed, according to which you can evaluate the correctness of automatic data binding.

For example, the entry:

11. Alekseevskaya-Smyshlyaevka - Alekseevskaya-Smyshlyaevka

1120.315 1120.326 - 11m [id: 4562]

means that the stage SAUT No. 11 "Alekseevskaya-Smyshlyaevka" is compared with the stage "Alekseevskaya-Smyshlyaevka" from a single database. The entry point in the SAUT database has an ordinate of 1,120 km 315 m, the entrance traffic light point in the EBS has an ordinate of 1,120 km 326 m, the error of linking is 11 m, which meets the reliability criterion - this stage will be imported into a single database.

The request to add information (KPD-3 data), generated using a program that implements the converter functions, is received from the PC 2 of the client's AWP to server 1, which contains information on the elementary sections of the tracks served by the depot in which the AWP is installed.

Module 8 selection of path segments is presented as part of a script to import data from a database (CAP EFFICIENCY) into a single database. The module at startup (at the command of a user from a personal computer 2 AWP client) authorizes and connects to the local database CAP Efficiency located on the AWP client, a request to the table Path ("Paths") of the local database, then based on the results obtained create a list the path efficiency existing in the CAP database, for each path forming a parametric query to the Otrezok table “Path segment” and redirecting the received data about the path segment to module 9 comparing stations belonging to the path segments.

In module 9 of the comparison, the correspondence of the path segment (CAP efficiency data) to the path segment (data from a single database) is determined, using the global station station membership code of the path segment. Path segments for which it is impossible to establish an unambiguous correspondence of codes of the access station are not converted. Then, in the comparison module 10, the correspondence of the boundaries of the track segments is checked and the railway coordinates of the starting points of the track segment are compared (according to the CAP efficiency data and a single database), and then the coordinates of the end points. If the difference in ordinates, at least on one of the points, exceeds 50 meters, the binding is considered not reliable, and this segment is not imported. To transfer the data of a path segment to a single database, a data import script is launched.

The CAP KPD data import script into a single database transfers data in the following order:

The module 11 for generating object data, calculating coordinates, and writing to server memory is presented as the last part of a script to import data from the CAP Efficiency database into a single database. Module 11 receives verified data about each segment of the path from module 10, through a database management system operating on server 1, generates a request to a single database and as part of the request transfers data about the segments of paths and objects located on them in the following order:

- Waypoint objects (from the PathObject table to the TrackObject table);

- Stations (from the Station table to the Station table);

- Platforms (from the Platform table to the TrainStop table);

- Nodes (from the Endlock, Switch, PathObject tables (only objects of the "path change point" type) to the Node table);

- Properties of objects by object types (in the TrackObjectProperty table):

railway kilometers from the Kilometer table (properties “number of kilometers ending on a kilometer column”, “Number of pickets”);

- arrows from the Switch table (properties “type of arrow”, “speed limit on the arrow”, “link to the station”);

- traffic lights from the Svetofor table (properties “Designation”, “Coding period”, “Type of traffic light”);

- Places for checking brakes from the tables BrakeCheckPlace and BrakeCheckNorm (properties "Type of brake check", "Type of movement", "Direction of use", "Speed for checking brakes", "Norm of the way for checking brakes");

- Constant speed limits from the PermRestriction table (the properties "Limiting speed", "Type of movement", "Maintain only with the head", "Condition for applying the restriction");

- Moving from the Crossing table (property "Moving Type");

- Slopes from the Incline table (the "Slope value" property);

- Curves from the Curve table (property "Curve Radius");

- Deadlocks from the Endlock table (property "Link to the station");

- Way change points (property "Link to station"). The value is calculated from the tables PathObject, PointOnPath;

- Paths (from the Path table to the Track table);

- Path segments (from the Otrezok table to the Segment table);

- Adjacent segments (from the Joint table to the Joint table);

- Points on the way (from the PointOnPath table to the PointOnTrack table);

- Standard station routes (from the StandardStationRoute table to the StandardStationRoute table) and station route segments (from the StandardStationRouteOtrezok table to the StandardStationRouteSegment table);

- Drivers (from the Peregon table to the Span table);

- Train circulation sections and hauls for them (from the tables TrainTrafficSection and PeregonForTrainTrafficSection in TrafficSection and TrafficSectionSpan, respectively);

- Trains, train routes and timetables (from the tables Train, Route, Schedule to the tables Train, Route, Schedule, respectively).

The transfer order is explained by the presence of relationships between database tables (links) and integrity constraints.

The request to add information (CLUB-U data), generated using a program that implements the converter functions, is received from the personal computer 2 of the client’s workstation to server 1, which contains in memory information about the location of travel objects (traffic lights, bridges, crossings, etc.) e.) and information on constant speed limits in the KLUB-U electronic map for sections of tracks served by the depot in which the AWP is installed.

The module 12 of selecting sections from the electronic map at startup (at the command of the user from the client workstation) accesses the file of the CLUB-U electronic map format tar located in one of the directories on the client workstation specified by the user in a dialog with the converter program. After reading the electronic map file, module 12 analyzes its contents and, based on the signs of the beginning and end of a section of an object of the kilometer column type, first determines the start and end kilometers of each individual section, and then, based on the information received, after reading from the file and forming a complete list of stations and paths for each section, defines the starting and ending stations and a set of possible paths for each section. The information received by module 12 enters the module 13 comparing the start and end station of the site, and then to the module 14 comparing the numbers of the paths of the site for reconciliation of information.

In module 13 of comparison, the correspondence of a site (according to CLUB-U) to a site in a single database is determined, and the names of the start and end stations of the site are used. Sites for which it is impossible to establish an unambiguous correspondence between the starting and ending stations are not converted.

Verification of the existence of paths in a single database is performed in module 14 by comparing the path numbers according to the CLUB-U and a single database. Sites for which it is impossible to establish unambiguous correspondence of track numbers in a single database and the CLUB-U database are not converted.

Module 15 calculating the coordinates of objects and writing to the server’s memory receives finally verified data about each section from module 14, then through a database management system operating on server 1, generates a request to a single database to add each of the paths of a separate section, then recalculating the coordinates located on the site of objects in accordance with the beginning of the paths, and then the formation of a request to add objects to a single database.
