[0045] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0046] Example

[0047] Figure 1 Schematic diagram of the structure of an online review system for engineering drawings provided by an embodiment of the present invention. Figure 1As shown, the online review system of the engineering drawings includes: an intelligent review module 11.

[0048] The intelligent review module 11 includes:

[0049] The project filling unit 111 is used to obtain the project information input by the user. The project information includes the basic information of the project and the design unit information. The basic information includes the project name, project number, project code, project type, technical standards, construction address and construction unit. The design unit information includes the unit name, organization code, unit address, design qualification, person in charge and contact person.

[0050] The material upload unit 112 is used to obtain the engineering drawings uploaded by the user, and the drawing format of the engineering drawings is DWG (Drawing), DXF (Drawing Exchange Format) or IFC (Industry Foundation Classes). The material upload unit 112 also supports the user to view the drawing name, drawing format and upload progress of the engineering drawings, and supports the user to preview and delete the uploaded engineering drawings.

[0051] The intelligent review unit 113 is used to identify the drawing format of the engineering drawing, select the corresponding target library according to the drawing format of the engineering drawing, parse the relevant entity and layer information of the engineering drawing through the target library, review the parsed engineering drawing, and obtain the review result. Among them, the engineering drawing may contain information such as graphics, text and annotations, and the present invention can accurately and efficiently extract this information, and parse and process it.

[0052] In the embodiment of the present invention, the intelligent review unit 113 may specifically include:

[0053] The drawing conversion subunit is used to identify the drawing format of the engineering drawing, select the corresponding target library according to the drawing format of the engineering drawing, and parse the engineering drawing through the target library. When the drawing format of the engineering drawing is DWG or DXF, the target library is the ODA (Open Design Alliance) library; when the drawing format of the engineering drawing is IFC, the target library is the IFC-related library, and the IFC-related library is the prior art, including IfcOpenShell (Open source IFC libraryand geometry engine) library and Xbim (eXtensible Building Information Modelling) library. In this way, the present invention is compatible with engineering drawings in DWG, DXF and IFC formats, and improves the compatibility of drawing formats.

[0054] The rule matching subunit is used to match the target review rule in the preset multiple review rules according to the construction address. Specifically, the present invention uses artificial intelligence technology to dynamically and efficiently decompose the engineering-related regulations of multiple regions and automatically parse and match their corresponding algorithms to obtain the review rules corresponding to each region (i.e., the preset multiple review rules). The multiple review rules can be stored in the preset rule library. The use of review rules can automatically detect errors, omissions or non-compliance in engineering drawings. The present invention supports the modification, addition and deletion of review rules at any time in the later stage, with high flexibility and scalability, and can quickly and cost-effectively adapt to changes in relevant regulations.

[0055] The review subunit is used to review the parsed engineering drawings according to the target review rules and obtain the review results. The review results may include a review report, which may include annotations of errors, omissions or non-compliance in the engineering drawings, and may also include corresponding modification suggestions. The system supports users to view the review report online, and also supports users to download the review report in word and pdf types. Users can modify and improve the engineering drawings according to the review report, and then submit them to the system for review again until the relevant review requirements are met.

[0056] In an embodiment of the present invention, the online review system for engineering drawings may further include: a knowledge graph module; the knowledge graph module includes:

[0057] The search unit is used to determine the first target entity node corresponding to the keyword in the preset knowledge graph according to the keyword input by the user when it is determined that the user needs to search the preset knowledge graph, highlight the first target entity node, and display the corresponding first specification file and the first related information.

[0058] In a specific example, the search unit includes a text input box and a search button. The user enters the word "building" (i.e., keyword) in the text input box and clicks the search button. At this time, the search unit determines that the user needs to search the preset knowledge graph, and determines the first target entity node corresponding to the building in the preset knowledge graph according to the word "building" entered by the user, including four entity nodes: building interior, width, building and open surface. These four entity nodes are highlighted, and the corresponding first specification file and first associated information are displayed. Here, the first specification file includes *** construction project building area calculation rules, etc., and the first associated information includes (building, calculation, width), (building, including, building interior), (building, calculation, open surface), (building, calculation, building spacing).

[0059] The first viewing unit is used to determine a third target entity node associated with the second target entity node in the preset knowledge graph after detecting that the user selects the second target entity node in the preset knowledge graph, highlight the third target entity node, and display the corresponding second specification file and the second association information. In addition, the second target entity node is also highlighted when it is selected.

[0060] In a specific example, assuming that the user selects the road red line entity node in the preset knowledge graph, the first viewing unit highlights the road red line entity node after detecting this situation, and determines the third target entity node associated with the road red line in the preset knowledge graph, including large shopping malls, amusement parks, gates, etc., highlights the third target entity node, and displays the corresponding second specification file and second related information. Here, the second specification file includes ***Construction Project Planning and Management Regulations, etc., and the second related information includes (large shopping malls, setbacks, road red lines), (amusement parks, setbacks, road red lines), (gates, setbacks, road red lines), etc.

[0061] The second viewing unit is used to display detailed information of the target specification file when it is detected that the user selects the target specification file in the first specification file or the second specification file.

[0062] In actual use, after the intelligent review unit 113 outputs the review result, if the user needs to manually review the review result, the user can view the review rules and preset knowledge graphs stored in the system, and manually review the review result based on them. The present invention provides a preset knowledge graph for the user to manually review the review result, which makes the user review convenient and can improve the accuracy of the user review result.
