Description

Technical Field

[0001] The embodiments of the present invention relate to the technical fields of image processing and data processing, and in particular to a method, device, equipment, medium and program for automated drawing review. Background Art

[0002] Train Control Center (TCC) is a general term for equipment used for train control in train operation control systems, generating route commands and speed information. It is a train control safety device installed at each station or relay station, and is connected to track circuits, computer interlocking, temporary speed limit servers, other station train control centers, balise ground electronic units, CTC (Centralized Traffic Control, centralized dispatching) and signal centralized detection to achieve functions such as track circuits, active balises, section direction and block control. Computer interlocking is a real-time control system based on computer technology, using communication technology, reliability and fault-tolerant technology, and "fail-safe" technology to achieve mutual relationships between signals, switches, and routes, which must follow certain procedures and meet certain conditions to operate or establish relationships. It is used for interlocking requirements of railway stations. Computer interlocking and train control center are two important subsystems in the station ground system.

[0003] At present, manufacturers of computer interlocking and train control center equipment still mainly rely on the traditional manual review mode of drawings. This process involves detailed manual interpretation of the design blueprint to manually extract the required information and then configure the corresponding drawing data for the engineering software. Specifically, after receiving the design blueprint, the computer interlocking or train control center manufacturer will manually conduct a technical review of the design blueprint. The person in charge of drawing review will extract key content information from the drawings and fill it into the integrated design sheet. After signing and confirming, it will be uploaded to SVN (subversion, an open source version control system). The person in charge of subsequent data configuration will manually compile the basic information table for data configuration based on the design blueprint and the integrated design sheet content, and then import the basic information table for data configuration into the auxiliary tool to generate a data configuration file.

[0004] In the process of realizing the present invention, the inventor found that the prior art has the following defects: there is no unified format for signal professional drawings throughout the railway, and designers will use various graphics to express drawing information, which makes it difficult for the computer system to accurately identify it. Design drawings may also have irregular layer settings, graphics objects placed in the wrong layers, etc., which affect the accuracy of recognition. The method of manually reviewing the relevant drawings of computer interlocking and train control center equipment has a review quality that is highly dependent on the auditor's familiarity and understanding of the relevant professional specifications, and has great subjectivity and uncertainty. After the drawing review process is completed, the summary and recording of key information depends on the template filling of the integrated design compilation form. This process also relies on manual operation and is prone to errors or omissions. Subsequently, the person in charge of engineering software data configuration needs to configure the software data based on the prompt information on these integrated compilation forms. This link also faces the risk of errors and omissions caused by human factors, which increases the complexity and uncertainty of the overall workflow. It can be seen that the method of manually reviewing drawings has problems such as low efficiency of manual data configuration and the inability to reliably guarantee accuracy.

[0040] Embodiment 1

[0041] Figure 1 This is a flowchart of a method for automated review of drawings provided in the first embodiment of the present invention. This embodiment is applicable to the case of automated review of drawings related to train systems. The method can be executed by an automated review device for drawings. The device can be implemented by software and / or hardware and can generally be integrated in an electronic device. The electronic device can be a terminal device or a server device. As long as it can be used to implement the automated review method for drawings, the embodiment of the present invention does not limit the specific device type of the electronic device. Accordingly, Figure 1 As shown, the method includes the following operations:

[0042] S110, obtaining train system related drawings; wherein the train system related drawings include station computer interlocking related drawings and / or train control center related drawings.

[0043] The train system related drawings may be drawings related to the train system, for example, drawings related to station computer interlocking and / or drawings related to train control center. Drawings related to station computer interlocking may be drawings related to the station computer interlocking system. Drawings related to train control center may be drawings related to the station train control center.

[0044] In an embodiment of the present invention, optionally, the platform for implementing the automated drawing review method may be referred to as a digital integrated design platform for computer interlocking and train control center equipment (hereinafter referred to as the digital integrated design platform). Figure 2 It is a structural schematic diagram of a digital integrated design platform provided in Example 1 of the present invention. Figure 3 is a system function diagram of a digital integrated design platform provided by the first embodiment of the present invention. In a specific example, Figure 2 As shown in the figure, the digital integrated design platform can adopt a C / S (Client / Server) structure, which is divided into a client and a server. The client can be responsible for presenting data to the user and providing an interactive interface, while the server is responsible for processing client requests and returning data. The client sends a request, and the server responds to the request and provides the required services. The digital integrated design platform adopts a front-end and back-end separation method for modular encapsulation. After the platform is modularized, data is transmitted in an interface manner, which is universal and scalable.

[0045] Specifically, all functions involved in the entire drawing automation review process can be used on the client. When connected to the server, the latest data package of the server can be downloaded to update and iterate the local data of the client, and the local data of the client can also be uploaded to the server. The server is mainly used to store basic data such as but not limited to: design drawings, electronic design drawings, data obtained after digitization, such as circuit types, etc., and update and iterate to manage data versions to ensure the integrity of basic data and save the latest version of the client. The client and server are on different computers and communicate through the network.

[0046] For example, Figure 3 As shown, the digital integrated design platform can provide functions such as signal drawing recognition, signal drawing digitization, interlocking drawing inspection, train control drawing inspection, drawing dual-source verification and system management.

[0047] Correspondingly, the signal drawing recognition function module provided by the client in the digital integrated design platform can obtain train system related drawings such as station computer interlocking related drawings and / or train control center related drawings, so as to perform automatic drawing review and processing based on the obtained train system related drawings. Optionally, multiple clients can perform automatic drawing review and processing on the same or different train system related drawings in parallel. Optionally, train system related drawings may include but are not limited to CAD (Computer Aided Design) type drawings and blueprint scan type drawings. Among them, blueprint scan type drawings may include but are not limited to PDF (Portable Document Format) type drawings and JPG (Joint Photographic Experts Group picture file) type drawings.

[0048] S120, automatically identifying the train system related drawings to obtain initial identification data of the drawings.

[0049] The initial drawing recognition data may be recognition data initially obtained after automatic recognition of drawings associated with the train system.

[0050] Correspondingly, after the client obtains the train system-related drawings, the signal drawing recognition module can be used to intelligently identify the train system-related drawings, mainly to identify graphic symbols, text, lines, etc. in the train system-related drawings, and obtain initial recognition data of the drawings.

[0051] Specifically, if the type of the drawings associated with the train system is a paper design blueprint, it can be first scanned into a PDF version of the scanned drawing, and the PDF version of the scanned drawing can be imported into the digital integrated design platform by reading. If the drawings associated with the train system are in JPG format or CAD format, they can be directly imported into the digital integrated design platform by reading.

[0052] The digital integrated design platform can automatically identify graphic symbols, text, lines and other information in the drawings associated with the train system. Specifically, it can identify the cover, directory, station plan, section plan, double-track and cable route diagram, interlocking table, frequency shift cabinet layout diagram, integrated cabinet layout diagram, signal lighting circuit diagram, turnout control circuit diagram, track circuit diagram, track power outage supervision circuit diagram, interlocking drive circuit diagram, interlocking acquisition circuit diagram, interlocking interface frame wiring diagram, train control drive circuit diagram, train control acquisition circuit diagram, train control interface frame wiring diagram, section automatic block direction circuit diagram, coded circuit diagram, field connection circuit diagram, 64D semi-automatic block circuit diagram, automatic station-to-station block circuit diagram, station-to-station connection circuit diagram, consent switch control circuit diagram, consent circuit diagram, crossing notification circuit diagram, simple hump, mechanized hump, braided line and hump inspection and other drawings.

[0053] S130, digitally process the initial identification data of the drawing to obtain digital drawing data.

[0054] The digital drawing data may be data obtained by digitally processing the initial identification data of the drawing.

[0055] It is understandable that since drawing recognition has a certain error rate, the initial drawing recognition data obtained by intelligently identifying the drawings associated with the train system may include misidentification information. After obtaining the initial drawing recognition data, the digital integrated design platform can digitize the initial drawing recognition data through the signal drawing digitization function module, such as performing data analysis, data processing and integration on the initial drawing recognition data, ensuring the uniqueness and traceability of each data and forming an internally connected processing logic and process, thereby obtaining digitized drawing data. Optionally, the signal drawing digitization function module can extract the key design information included in the initial drawing recognition data and establish a drawing recognition library. Based on big data and data mining technology, through data analysis, processing and integration, it can realize the automated processing of signal drawings and data-driven design analysis.

[0056] Optionally, digital processing can refer to the use of information systems, various sensors, and information and communication technologies such as machine vision to transform the complex and ever-changing data, information, and knowledge in the physical world into a series of binary codes, which are introduced into the computer to form recognizable, storable, and computable numbers and data, and then these numbers and data are used to establish relevant data models for unified processing, analysis, and application.

[0057] S140, performing single-source verification on the digitized drawing data to obtain a single-source verification result.

[0058] The single-source verification result may be a result obtained by verifying the digitized drawing data corresponding to a type of drawing.

[0059] Correspondingly, the digital integrated design platform can digitize the initial identification data of the drawing through the signal drawing digitization function module to obtain the digitized drawing data, and then further perform single-source verification on the digitized drawing data. Specifically, the digital integrated design platform can perform a correctness review on the digitized drawing data of the station computer interlocking related drawings through the computer interlocking drawing inspection function module, generate an inspection result table and related results files, etc., to obtain the single-source verification results corresponding to the station computer interlocking related drawings. At the same time, the digital drawing data of the train control center related drawings can also be reviewed for correctness through the train control center drawing inspection function module, and an inspection result table and related results files can be generated to obtain the single-source verification results corresponding to the train control center related drawings.

[0060] S150, performing dual-source verification on the digitized drawing data to obtain a dual-source verification result.

[0061] Among them, the dual-source verification result can be the result obtained by comparing and verifying different versions of the same drawing.

[0062] It is understandable that some drawings usually have different versions. For example, the same drawing may include both a CAD version and a PDF version, or the same drawing may include different CAD versions, or different PDF versions, etc. Therefore, in order to ensure the accuracy of the drawing data, the digitized drawing data corresponding to the station computer interlocking related drawings and / or the train control center related drawings can also be dual-source checked. Specifically, the digital integrated design platform can perform dual-source verification on the digitized drawing data through the drawing dual-source verification function module to ensure the consistency and correctness of different versions of drawing sources. The drawing dual-source verification function module can use automated processing and comparison algorithms to achieve data comparison and verification between different versions of digitized drawing data, and generate a verification result table to record inconsistencies, thereby obtaining dual-source verification results.

[0063] S160. Generate a target audit result of the train system associated drawings according to the single-source verification result and the dual-source verification result.

[0064] Among them, the target audit result can be the final audit result obtained by automatically auditing the drawings related to the train system.

[0065] Correspondingly, after the digital integrated design platform obtains the single-source verification results and the dual-source verification results, it can count and organize the single-source verification results and the dual-source verification results to generate the final target review results of the train system related drawings.

[0066] For example, Figure 3As shown, the system management function module of the digital integrated design platform is mainly used to maintain and manage the system data of the digital integrated design platform. The system management function module may include but is not limited to equipment management, drawing management, project management, menu management, user management and role management. Among them: the equipment management module is mainly used to manage the signal equipment data that the platform needs to identify, so as to facilitate the filtering and statistics of the identification data by the identification module. The drawing management module is mainly used to manage all imported drawings, and can view and delete operations by clicking the corresponding drawing information. The project management module is mainly used to manage different projects and basic data, which is convenient for use in other modules, and at the same time, simple statistics are performed on the basic data related information. The menu management module is mainly used for project administrators to maintain all menu information of this platform, including functions such as adding, deleting and modifying. The user management module includes two parts: user list and user addition, and can add, modify and delete user information by clicking. The digital integrated design platform can also realize the entry, editing and deletion of various user roles through the role management module, and can assign different permissions according to different user roles.

[0067] The above technical solution automatically completes the automatic review of the drawings related to the train system through the digital integrated design platform, which can ensure that the automated drawing review system can accurately determine whether the drawings meet the requirements of various specifications, realize the automation of drawing compliance review, and ensure that the automated drawing review system can maintain a high recognition accuracy rate under various circumstances, and can also reduce false positives and false negatives, and improve the reliability of the drawing review results. At the same time, the automated drawing review system is integrated with other related systems to achieve data sharing and process optimization, and ensure the security of system data and the protection of user privacy.

[0068] The embodiment of the present invention obtains train system related drawings such as station computer interlocking related drawings and / or train control center related drawings to automatically identify train system related drawings, obtain initial identification data of drawings, further digitize the initial identification data of drawings, obtain digitized drawing data, and then perform single-source verification on the digitized drawing data to obtain single-source verification results, and perform dual-source verification on the digitized drawing data to obtain dual-source verification results. Finally, the target review results of the train system related drawings can be generated according to the single-source verification results and the dual-source verification results, which can solve the problems of low configuration data efficiency and accuracy in the existing manual review of train system related drawings, and can improve the accuracy, efficiency and reliability of drawing review.

[0069] Embodiment 2

[0070] Figure 4is a flow chart of a method for automatic drawing review provided by the second embodiment of the present invention. This embodiment is specific based on the above embodiment. In this embodiment, specific optional implementation methods for automatic identification of drawings associated with train systems, digital processing of initial identification data of drawings, and single-source verification and dual-source verification of digital drawing data are provided. Figure 4 As shown, the method of this embodiment may include:

[0071] S210, obtaining train system related drawings; wherein the train system related drawings include station computer interlocking related drawings and / or train control center related drawings.

[0072] S220, automatically identifying the train system related drawings to obtain initial identification data of the drawings.

[0073] In an optional embodiment of the present invention, the automated identification of the train system associated drawings to obtain initial drawing identification data may include: extracting images of the train system associated drawings, and preprocessing the extracted images to obtain preprocessed drawing images; performing image segmentation on the preprocessed drawing images to obtain segmented drawing images; performing feature extraction on the segmented drawing images, and identifying image symbols and symbol classifications in the segmented drawing images based on the extracted features; performing text recognition on the preprocessed drawing images to obtain text recognition results; and recognizing tables included in the preprocessed drawing images to obtain table recognition results.

[0074] The pre-processed drawing image may be an image obtained by pre-processing an image extracted from a train system-related drawing. The segmented drawing image may be an image obtained by segmenting the pre-processed drawing image. The image symbols may include circuit symbols and non-circuit symbols.

[0075] In an embodiment of the present invention, when the drawings associated with the train system are automatically identified, the relevant image processing library and tools can be used to accurately read the drawings associated with the train system, such as CAD and blueprint scanned electronic files (PDF / JPG) to obtain the corresponding images, and the images extracted from the drawings are preprocessed by graying, filtering, and binarization to improve the image quality and subsequent processing efficiency, so as to obtain the preprocessed drawing images. Further, a suitable image segmentation algorithm can be used to segment the preprocessed drawing images into different regions so as to better extract features and obtain segmented drawing images. After obtaining the segmented drawing images, feature extraction can be performed on the segmented drawing images, and the drawing images can be deeply analyzed to extract key features such as lines, shapes, colors, and textures. Optionally, advanced machine learning algorithms such as convolutional neural networks and support vector machines can be used to train and learn the extracted features, so as to identify image symbols and symbol classifications in the segmented drawing images according to the extracted features. Among them, the image symbols can include but are not limited to symbols, signs, and graphics in the image, and when identifying the image symbols in the segmented drawing images, the image symbol meanings and attribute information can be extracted. For the text in the pre-processed drawing image, the optical character recognition (OCR) algorithm can be used to convert the text in the pre-processed drawing image into editable and searchable text to obtain the text recognition result. For the table included in the pre-processed drawing image, the CAD software secondary development method can be used based on the tool that can export 3D CAD objects to a specific format to identify the table content included in the pre-processed drawing image, and finally encapsulate it into JSON (JavaScript Object Notation) format.

[0076] It should be noted that when using machine learning models to extract image features, a large amount of drawing data needs to be annotated in advance to provide sufficient training data for the machine learning model and continuously optimize and improve the performance of the machine learning model. After the machine learning model is trained, it is also necessary to use various evaluation indicators to evaluate the trained machine learning model, and optimize and adjust the machine learning model according to the evaluation results to improve the recognition accuracy and stability. The recognition method of the circuit diagram can be: exporting it as a picture in the form of points, lines and surfaces, and performing AI (Artificial Intelligence) recognition on the equipment in the picture, that is, the artificial neural network method. When using the artificial neural network method to recognize the circuit diagram, it is necessary to classify and summarize all the icon sample data to be recognized, make a label set, perform machine training, generate a neural network model, and it is necessary to repeatedly iterate the AI ​​recognition system to train the drawings to improve the recognition accuracy. The recognition results of the circuit diagram can be compared with the component library to obtain a list of all components in the drawing.

[0077] S230: Perform data structuring processing on the initial identification data of the drawing to obtain a data model of the digitized drawing.

[0078] The data model of the digitized drawing may be a data model obtained by assigning a certain data structure to the initial identification data of the drawing.

[0079] Specifically, when the initial identification data of the drawing is digitized, the classified symbols and elements included in the initial identification data of the drawing can first be data-structured, a data model of the digitized drawing can be established, and the structure and layout of the drawing can be reconstructed according to the hierarchy, association relationship and layout rules of the drawing.

[0080] In an optional embodiment of the present invention, the data structuring processing of the initial identification data of the drawing to obtain the data model of the digitized drawing may include: digitizing the table data included in the initial identification data of the drawing based on the station; wherein the table data includes at least one of the table ID, the drawing file name, the signature column and the table type; digitizing the electrical component data included in the initial identification data of the drawing according to the electrical component type; digitizing the plan view identification data included in the initial identification data of the drawing according to the equipment type; wherein the plan view identification data includes at least one of the turnout, the signal machine, the track circuit, the insulating joint and the platform; structuring the results of each digitization processing according to the set data structure to obtain the data model of the digitized drawing.

[0081] The set data structure may be, for example, a JSON structure, a database, or a spreadsheet, and the embodiment of the present invention does not limit the specific data structure type of the set data structure.

[0082] In an embodiment of the present invention, when data structuring is performed on the initial identification data of the drawing, corresponding data structuring processing methods can be adopted according to the element types. Specifically, when data structuring is performed on the table identification data in the initial identification data of the drawing, the data taken out of the table can be divided into table data such as table ID, drawing file name, signature column and table type, and different fields can be defined according to different table data types. The data taken out of the table can be saved in the form of "drawing name + table name" to maintain uniqueness. A station defines different fields according to different table data types. Tabular data can be used for circuit inspection and connectivity inspection, such as leak detection and error correction.

[0083] In a specific example, for the storage of interlocking combination cabinets, the information that needs to be obtained is as follows: cabinet name: identify and read combination cabinets such as 11~23; zero layer information: set at the top or bottom of the combination rack, which is determined according to the wiring of the drawing; number of layers: determine the maximum number of layers of the combination cabinet, and take the maximum layer number as the maximum number of layers; layer information_layer number: for example, 12-3 represents the third layer of the second rack in the first row; layer information_device name: the signal device corresponding to the combination; layer information_combination name; layer information_combination internal: the internal relay structure of the combination; Layer information_controlled equipment: the name of the turnout or signal controlled by the combination; Layer information_side terminal_terminal row number; Layer information_side terminal_terminal number: such as 12-203-2 means the 1st row, 2nd frame, 2nd floor, 3rd column, 2nd position; Layer information_side terminal_connecting terminal: such as 1F-402-1 means the wiring between the distribution board; Layer information_side terminal_pointing terminal: such as 1006-16 means connected to the 10th floor, 6th column, 16th position of the same combination cabinet; Layer information_side terminal_terminal type, etc.

[0084] The functions of the tabular data obtained by data structuring processing include the following: it can be compared and verified with the quantity and name of the equipment layout information of the combination cabinet; it can be checked with the number and name of equipment in the indoor equipment plan layout of a station; it can be compared and verified with the name and quantity of the combination arrangement table; it can prepare and compare the connection of the wiring on the side of the combination cabinet; indoor equipment layout.

[0085] The electrical component data included in the initial identification data of the drawing is digitized according to the electrical component type. The electrical components extracted from the circuit drawing may include the electrical component ID, the drawing file name, the signature column, and the component type. Different fields can be defined according to different electrical component types to extract relevant data from the identification results. In a specific example, taking the resistor component as an example, the data that can be extracted include the component type: resistor; the resistance value: the identified resistance value; the position information: the position coordinates of the component on the drawing. Taking the capacitor component as an example, the data that can be extracted include the component type: capacitor; the capacitance value: the identified capacitance value; the position information: the position coordinates of the component on the drawing. Taking the power supply component as an example, the data that can be extracted include the component type: power supply; the power supply type: the identified power supply type, such as DC power supply or AC power supply, etc.; the position information: the position coordinates of the component on the drawing. The extracted electrical component data can be stored in a specified data structure, such as a database or a spreadsheet. Each electrical component can be a record containing corresponding field values. The electrical component ID can be used as a unique identifier, and the data of all components can be stored in the same table.

[0086] When the plan view identification data included in the initial identification data of the drawing is digitized according to the equipment type, the turnouts, signal machines, track circuits, insulation joints, platforms, etc. extracted from the plan view include data such as equipment ID, drawing file name, and signature column, and different fields are defined according to different equipment types. In a specific example, taking the signal machine as an example, the attributes or information of the equipment identified in a certain signal machine diagram can be: signal machine type (such as exit signal machine), name (such as S3), high and low columns (such as low columns), light positions (such as five light positions), signal machine control type (such as two-direction four-display exit signal machine with shunting) and the throat to which it belongs (such as the downlink throat). The attributes or information included in the signal machine image can be represented as data in JSON format.

By automating the consistency check of electronic drawings and paper blueprints, the workload and error rate of manual comparison can be reduced. By generating target audit results, the inconsistencies between electronic drawings and paper blueprints can be clearly recorded, facilitating subsequent processing and correction.

[0120] It can be seen that all the standardized contents involved in the above technical solutions are logically judged by the computer of the digital integrated design platform, which ensures the correctness of the drawing review and improves the efficiency of the drawing review.
