[0061] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0062] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0063] The first embodiment of the present invention provides a method for automatically verifying digital data of railway signal drawings. Figure 1 Provide detailed explanation.

[0064] like Figure 1 As shown, in step S100, digital data of railway signal drawings are obtained.

[0065] Railway signal two-dimensional drawings cannot be directly read and used by computer programs. In this embodiment, the designed two-dimensional drawings (or as-built drawings) are used as system input, and the digital processing module completes the digital processing, converting the drawing data into a data structure form that can be directly used by the computer and storing it in the drawing data digital library. Figure 2 As shown in the figure, the reverse digitization of drawing data mainly includes two key steps: obtaining the original drawing data and analyzing and storing the data.

[0066] (1) Obtaining original drawing data

[0067] The outdoor drawing data mainly includes the signal equipment layout diagram and the relevant data in the two-line cable route diagram. The key data is imported into the system after manually filling out the EXCEL table according to the drawings.

[0068] Indoor drawing data mainly includes data related to station interlocking, coding, section blocking, special combination circuits, etc., including layout diagrams of various cabinet equipment, wiring diagrams of various cabinet sides, internal wiring diagrams of various combinations, power wiring diagrams, etc. These drawings are all forms of various types. Taking coding as an example, coding indoor cabinets are mainly divided into three types: coding frequency shift cabinets, coding integrated cabinets, and coding combination cabinets. The frequency shift cabinets are mainly equipped with coding transmitters, the integrated cabinets are mainly equipped with lightning protection equipment for the coding section, indoor isolation equipment, and transmission matching lightning protection units, etc. The combination cabinets are mainly used to place relays used in coding circuits.

[0069] The meanings of the various wiring diagrams on the side of the cabinet are as follows:

[0070] Track cabinet side wiring diagram:

[0071] 1. The example of track cabinet name in the wiring diagram is as follows Figure 3 shown.

[0072] 2. The side wiring is explained using G1-102-3 as an example. Figure 4 shown.

[0073] 3. The side wiring of the track cabinet can be divided into the following categories:

[0074] (1) Wiring between the sides of the interlocking assembly: such as 13-1005-5;

[0075] (2) Wiring between the coded integrated cabinet: such as Z1-702-1, Z1-702-2;

[0076] (3) Wiring between the distribution board: such as 1F-102-3;

[0077] (4) Wiring between the track test disk (related to the location of the test disk);

[0078] (5) Wiring between track cabinet

[0079] ① Wiring with other track cabinets: For example, G2-503-9 means the 9th position of the 3rd column of the 5th layer of the G2 cabinet;

[0080] ②Wiring between different combinations of the same track cabinet: For example, 503-9 means the 9th position in the 3rd column of the 5th layer in the same track cabinet;

[0081] ③ Wiring with this combination: For example, 03-2 means the second position in the third column of the same floor of the same track cabinet;

[0082] (6) Power loop

[0083] If the following words "KZ, KF, JJZ220, JJG110, JJF220" appear in the track cabinet, it is considered to be the power supply required for this combination. If non-related words appear, an error will be reported. "D-" indicates the zero-layer terminal of the power supply of this combination cabinet.

[0084] ①Logic power supply KZ, KF:

[0085] Seen in the W25 and GT combinations in the track cabinet, the loop line is divided into the following three types:

[0086] The power loop between this combination is as follows: 01-9~03-3(KZ);

[0087] Power loop line between other combinations: 306-1~506-1(KZ);

[0088] The loop line between the zero floor of this cabinet is G1-903-2~D1-2;

[0089] ②Track circuit power supply JJZ220, JJG110, JJF220

[0090] Found in the W25 and GT combinations in the track cabinet, the loop lines are divided into the following two types: the power loop line between other combinations: G1-901-5~G1-509-1(JJZ220); the loop line between the zero layer of this cabinet such as G1-901-7~D2-2.

[0091] Taking CAD drawings as input, computer technology is used to complete sub-image splitting, sub-image filtering, sub-image original data extraction and other tasks. Finally, the tables in such drawings are converted into Excel tables (memory form) that are easy to interpret and calculate. The Excel table structure is exactly the same as the table in the drawing.

[0092] (2) Data analysis and storage

[0093] As the tables in the drawings are fixed in format and limited in number, the characteristics of the same table type are manually analyzed and extracted, and the feature matching algorithm is used to match the original data Excel table for data parsing. At the same time, each character in the drawing table has a specific meaning. The completion rules for its complete meaning are extracted according to the drawing design habits / standards, and all the data in the table are given specific meanings. For example, all terminal characters are completed with the three-level complete meaning of "cabinet name-cabinet layer-terminal". For example, the data "5" is written on the 01-3 terminal table of cabinet 11 on the 2nd floor. The algorithm can fully parse "05" into "11-201-5".

[0094] According to the characteristics of the signal system, a digital data structure of 8 levels of drawings is designed, namely "station -> station / section -> interlocking / coding / blocking -> cabinet -> cabinet layer -> side / interior -> equipment -> terminal". The key attribute information and relationships of some data structures are as follows: Figure 5 As shown, the tabular digital data is as follows Figure 6 As shown. Finally, the original drawing data is converted into structured data that can be directly interpreted and used by computer programs, and the inclusion and pointing relationship between the data is established to realize the reverse digitization of the signal drawing. Finally, the digitized drawing data is stored in the database for direct access and data management in subsequent links.

[0095] like Figure 1 As shown, in step S200, based on the preset verification rules, the digital data of the railway signal drawing is subjected to single static verification, errors and risk points are found, and the results are recorded and analyzed to form a static verification report;

[0096] The static verification includes the compliance of wiring double-end reflection, the correctness of relay type, and the static verification rules of power loop wiring.

[0097] During the design process, drawings may contain basic data errors, such as single-end reflection, power wiring not forming a loop, relay type error, etc. According to different error characteristics, through targeted preset inspection rules, single-item static verification of the digital data of the drawings is automatically performed to find errors and risk points, and record and analyze them to form a static verification report. The inspection rules are extensible. This embodiment designs three static verification rules: wiring double-end reflection compliance, power loop wiring forming a loop, and relay type correctness.

[0098] (1) Static verification rules for wiring compliance at both ends, such as Figure 7 Shown

[0099] Read the digital data of the entire station;

[0100] Sequentially obtain a combined internal and side terminal data;

[0101] Traverse the side terminals of the combination and verify whether the side terminals comply with the double-terminal reflection. If not, add them to the error list. The basic rule of the double-terminal reflection is: if the data at terminal A is filled with connection terminal B, the data at terminal B must be filled with connection terminal A;

[0102] Determine whether the side terminals of the combination are traversed. If the traversal is completed, traverse the internal terminals of the combination and verify whether the internal terminals meet the double-end reflection. If not, add them to the error list.

[0103] Determine whether the internal terminals of the combination have been traversed, and if so, take the next combination for verification;

[0104] Determine whether there is an unverified combination. If not, end the verification.

[0105] (2) Static verification rules for relay type correctness, such as Figure 8 Shown

[0106] First, based on the standard drawings within each type of combination, extract and organize the types of equipment that should be placed in the equipment positions within each combination in the standard drawings to form the underlying configuration file for the system. The specific configuration items and corresponding contents are shown in the table below.

[0107]

[0108]

[0109] The specific verification process is as follows:

[0110] Read the digital data of the entire station;

[0111] Read the internal data of a group in the order of group position number;

[0112] Obtaining the underlying configuration files of the equipment types of the internal equipment positions of the current combination from the pre-built underlying configuration files library of the equipment types of the internal equipment positions of various standard combinations;

[0113] Compare the equipment type of each equipment position in the current combination with the data in the underlying configuration file one by one. If no inconsistent items are found, the verification is passed. If inconsistent items are found, they are added to the error list and the error situation is recorded;

[0114] After the current combination is verified, the next combination is taken for verification;

[0115] Determine whether there is an unverified combination. If not, end the verification.

[0116] (3) Static verification rules for power supply line wiring, such as Fig. 9 As shown, specifically including:

[0117] The power loop wiring verification is divided into two parts: one is the combined internal power loop wiring verification, with a combination as the basic verification unit; the other is the combined side power loop wiring verification, with the 1st to 10th floors of a combination cabinet / track cabinet as a basic verification unit.

[0118] 1. Combine the internal power loop wiring into a ring verification rule, with one combination as the basic verification unit:

[0119] Read the digital data of the entire station;

[0120] Read the internal data of a combination according to the combination position number sequence, obtain the internal power wiring terminal data therefrom, and group the power wiring terminals according to the power type;

[0121] Sequentially select a power group, take any terminal in the current group as the starting point, and perform recursive search according to the wiring relationship. If the starting terminal can be found recursively to form a wiring loop and the power type of each terminal in the recursive path is consistent with the starting terminal, the current group verification passes, otherwise it is added to the error list and the error situation is recorded;

[0122] After the current group is verified, the next group is taken for verification. After all groups in the current combination are verified, the next combination is taken for verification.

[0123] Determine whether there is an unverified combination. If not, end the verification.

[0124] 2. Combined side power supply loop wiring ring verification, with the 1st to 10th layers of a combined cabinet / track cabinet as a basic verification unit:

[0125] Read the digital data of the entire station;

[0126] Read the side wiring data of a combination cabinet according to the combination cabinet number sequence, obtain the side power wiring terminal data therefrom, and group the power wiring terminals according to the power type;

[0127] Sequentially select a power group, take any terminal in the current group as the starting point, and perform recursive search according to the wiring relationship. If the starting terminal can be found recursively to form a wiring loop and the power type of each terminal in the recursive path is consistent with the starting terminal, the current group verification passes, otherwise it is added to the error list and the error situation is recorded;

[0128] After the current group verification is completed, the next group is taken for verification. After all the group verifications of the current combination cabinet are completed, the next combination cabinet is taken for verification;

[0129] Determine whether there is an unverified combination cabinet. If not, end the verification.
