[0002] The existing engineering design work is still in the stage of transition from paper to paperless. When using a paperless method to manage drawing files, the designer needs to open and check the drawing files one by one when checking the drawing data. The storage location and storage method of the drawing files all depend on the designer's own habits. Therefore, drawings from different designers and different types of drawings often exist separately in the personal folders of each designer, or are randomly stored by the designer in various locations of the engineering folder. The above situation causes great inconvenience to the viewing and management of drawings. On the other hand, during the drawing viewing process, the current software does not display the information of the number of drawings in the drawing file clearly, and cannot intuitively understand the situation of the drawings in the drawing file.

[0048] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0049] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-described accompanying drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product or device.

[0050] The embodiments of the present application provide a drawing management method applied to a cloud service centralized drawing management platform, as shown in the drawing management platform 1000, the method can include the following steps: Figure 1

[0051] Step 101, receiving a first version drawing file and determining a drawing to be updated, the drawing to be updated is a set of drawings in the first version drawing file different from a second version drawing file, and the second version drawing file is stored in the drawing management platform.

[0052] In an exemplary embodiment, the first version drawing file includes M drawings, and the second version drawing file includes N drawings; receiving the first version drawing file and determining the drawing to be updated includes: performing the following processing on each drawing in the M drawings: calculating the hash value of the drawing and the hash value of the N drawings in the second version drawing file and comparing them to obtain a first comparison result; when the first comparison result is that the hash value of the drawing is different from the hash value of each drawing in the second version drawing file, the drawing is added to the drawing to be updated.

[0053] ​It should be understood that multiple version drawing files can be included in the drawing management platform, and when a first version drawing file is uploaded, these version drawing files can be sequentially executed as second version drawing files to implement comparison of the first version drawing file with all version drawing files in the platform.

[0054] In actual application, a common case of receiving a drawing file is that a drawing designer submits a new version drawing file after modification as a first version drawing file, and at this time, the second version drawing file is a current version drawing file already stored in the drawing management platform. For the purpose of facilitating understanding (repeated use of the description of “first version” and “second version” will bring difficulty to the understanding of readers), “new version drawing file” and “current version drawing file” will be used instead of “first version drawing file” and “second version drawing file” in the following description of step 101. Of course, uploading a new version drawing file is only one use of the method, and in other cases, such as supplementally uploading an old version drawing file that has been forgotten to be uploaded, the method can still be used to complete uploading of the drawing based on the original description.

[0055] Generally, the new version drawing file includes M drawings, and the old version drawing file includes N drawings, M and N are natural numbers and greater than 0. The drawing management platform will sequentially calculate the hash value of each drawing in the new version drawing file and compare it with the hash value of each drawing in the old version drawing file (the hash value of the old version drawing file is generally calculated when it is uploaded, and if it is not calculated, it can be calculated in this step). For example, when drawing A is judged, if the same hash value as that of drawing A cannot be detected in the old version drawing file, it is considered that drawing A is a new drawing, and drawing A needs to be added to the drawing to be updated and updated to the drawing management platform.

[0056] If the comparison result shows that the hash values of the two drawings are the same, it is considered that drawing A is a repeated upload of the designer, and at this time, the drawing management platform will not consume bandwidth and storage resources to perform subsequent analysis and upload of drawing A, but in the subsequent update step, the data of drawing B will be directly linked to drawing A, that is, incremental update. The drawing management platform will not perform subsequent processing on the hash value consistent drawing file, and only the changed part of the new version drawing file will be updated, thereby realizing incremental update of the drawing.

[0057] In an exemplary embodiment, after obtaining the first comparison result, it further includes: when the first comparison result is that the hash value of the drawing is the same as the hash value of the first drawing in the second version drawing file, an index relationship is established between the drawing and the first drawing, and the index relationship indicates that the data of the drawing is derived from the first drawing.

[0058] In the above, the concept of "incremental update" has been proposed, that is, the drawing management platform will not waste resources to save and parse the same drawing repeatedly. Specifically, in order to no longer upload the repeated drawing A, an index relationship can be established to associate the files of drawing A and drawing B. In actual application, all drawing files with the same content are saved only once, but the drawing can appear in different locations of the entire project through the index relationship. For example, there are two drawings of "bedroom" in the drawing files of "building 1" and "building 2", respectively, but these two drawings are actually stored only once, and they are displayed by introducing the content of a drawing named "bedroom" into "building 1" and "building 2" through the index relationship.

[0059] Step 102, based on the drawing to be updated, determine the drawing update content, and the drawing update content takes the frame in the drawing as the smallest data management unit.

[0060] In an exemplary embodiment, based on the drawing to be updated, determining the drawing update content comprises: extracting all frame data in the drawing to be updated and taking it as the drawing update content, each drawing in the drawing to be updated comprises at least one frame, and each piece of frame data in the frame data has an identification for identifying the piece of frame data and an attribute of the piece of frame data.

[0061] In drawing design, electronic drawings can be stored in the form of.dwg suffix. According to the habit of designers, a single drawing can include multiple frames, that is, a single.dwg file can include multiple frames. For example, some designers will pack the bedroom drawings of three house types in building 1 in one.dwg, so "bedroom.dwg" will include at least three frames (at least one corresponding frame for each house type). But some designers will choose to upload "bedroom A.dwg", "bedroom B.dwg" and "bedroom C.dwg" three files respectively. When the drawings of multiple designers are uploaded together, these different design habits may cause problems. Therefore, the above scheme is designed. The drawing management platform will use the drawing parsing engine to parse and extract all frame data in each.dwg. After extraction, all uploaded drawing data can uniformly take the frame as the management unit, which facilitates the management of drawings.

[0062] Since the drawing to be updated has been determined in step 101, only the above frame extraction step needs to be performed on the drawing to be updated, and after extraction, all frames are displayed on the drawing management platform. In order to identify the ownership of each frame, an identification such as "professional + sub-item + drawing number + drawing name" can be added to each frame. Each frame also has its own drawing attributes, for example: professional, stage, sub-item. The signing column of the drawing will include these drawing attributes.

[0063] In step 103, the drawing update content is obtained based on the drawing update content, and the drawing update content and the drawing update situation are uploaded.

[0064] In an example embodiment, the drawing update content includes P drawing frame data of P drawing frames; and the drawing update situation is obtained based on the drawing update content, including: performing the following processing on the drawing frame data of each of the P drawing frames: extracting the graphic element data in the drawing frame data; comparing the graphic element data with the graphic element data of N drawings in the second version of the drawing file to obtain a second comparison result; when the second comparison result is that the graphic element data is the same as the first graphic element data in the graphic element data of N drawings in the second version of the drawing file, setting the drawing update situation of the drawing frame data corresponding to the second comparison result as no change, or when the second comparison result is that the graphic element data is different from the graphic element data of N drawings in the second version of the drawing file, setting the drawing update situation as modification or addition.

[0065] The drawing update situation is used to indicate which contents in the uploaded drawing are updated. In order to compare in detail and accurately, the graphic elements in the drawing frame need to be extracted. The present application provides four update situations, respectively "add" - the drawing management platform does not have the drawing frame; "modify" - the drawing management platform already has the drawing and the drawing frame, but the graphic element data has changed; "no change" - the drawing management platform already has the drawing and the drawing frame and the graphic element data is completely the same; "delete" - after the comparison of the drawing frame data in the drawing update content is completed, the remaining drawing frame in the second version of the drawing file is not compared and is deleted.

[0066] It should be understood that "add" and "modify" are both found by comparing different graphic element data in the drawing frame. The difference between the two is that in the "modified" drawing frame, a large number of graphic element data is the same as the drawing frame data before modification. Therefore, the proportion of the same graphic element data in all graphic element data in the drawing frame can be used to determine whether the update situation of the drawing frame is "add" or "modify".

[0067] It should be understood that the identification and attributes of each piece of drawing frame data can also be used for comparison to obtain the drawing update situation.

[0068] In an example embodiment, after uploading the drawing update content and the drawing update situation, the method further includes: obtaining a historical version drawing viewing instruction, the historical version drawing viewing instruction indicating to display a historical version of a second drawing in the drawing file stored in the drawing management platform; and based on the historical version drawing viewing instruction and the drawing update situation corresponding to the second drawing, generating and displaying a second drawing historical version list.

[0069] It should be understood that after the uploading of the drawing is completed, the drawing management platform displays the uploaded drawing, and the designer generally uses the latest version of the drawing for work. However, the previously uploaded drawing file is not directly deleted, but is saved as a historical version. When the designer wants to view the drawing uploaded at a previous time for comparison or reference, the drawing management platform can be instructed to view a certain historical version, and the drawing management platform displays the drawing file of the historical version for the designer to refer to.

[0070] When displayed, the historical version of the drawing can be additionally marked according to the drawing update. For example, the newly added drawing file in the historical version is highlighted.

[0071] The drawing management method described above is illustrated by a specific embodiment as shown in the following. Figure 2

[0072] Step 201, file name judgment

[0073] Each time the drawing is updated, the hash values of the drawing files are compared. If the hash values are consistent, it is considered that the drawing file is a repeated upload of the old version of the drawing file. If the hash values are inconsistent, it is considered that the drawing file is a new file, and the block data is parsed and identified.

[0074] It should be noted that the hash value is calculated based on the content of the drawing file, not the hash value of the drawing file name. The MD5 method can be used to calculate the hash value.

[0075] If the hash value of the newly uploaded drawing file this time is consistent with the hash value of the drawing file already existing in the old version of the drawing file, only the index relationship is updated, and the block data in the newly uploaded drawing file this time is no longer parsed. If the hash values are inconsistent, the parsing and extraction of step 202 are performed.

[0076] Step 202, data extraction

[0077] The drawing block data is parsed and extracted from the drawing using a drawing parsing engine. The identification of each piece of drawing block data obtained is “major + sub-item + drawing number + drawing name”, and each piece of drawing block data further includes some drawing properties (for example, major, stage, sub-item, etc.). The signing column of the drawing includes these drawing properties.

[0078] Step 203, obtaining update information

[0079] Each piece of drawing block data can be associated with different versions of the drawing source file. Through the update time in the update information and the index relationship between the block and the drawing source file, the drawing of each local update can be accurately located.

[0080] The following illustrates an example of the updating process as shown in the following.​Figure 3 As shown in the following table 1 and table 2

[0081] Suppose that the drawing file A contains four frames, namely frame 1, frame 2, frame 3 and frame 4. After modification, the drawing file A is saved as drawing file B, which contains drawings of frame 2, frame 3, frame 4' and frame 5. The drawing update is as follows: the first drawing file A is uploaded to update four frames; the second drawing file B is uploaded to delete frame 1, modify frame 4 and add frame 5.

[0082] Table 1

[0083]

[0084]

[0085] Table 2

[0086]

[0087] The drawing management platform compares the drawing frame identifier and the drawing data in the frame. If the comparison is consistent, the drawing is overwritten. If the comparison is inconsistent, it is further determined whether it is new or modified. In this way, the drawing update is orderly and the version coverage is controllable.

[0088] It should be particularly noted that the above example explains the case where a single drawing file includes multiple frames. For the case of multiple drawing files, the update of each drawing file can be obtained and summarized in sequence.

[0089] Step 204, historical version drawing display

[0090] The user can filter the drawings in different versions according to the "major + sub-item + drawing number + drawing name" to generate a list and display it. The user can load the drawing through the web-based drawing browser and quickly switch the frame data of "major + sub-item + drawing number + drawing name" in different historical versions to realize the switching and comparison display of the same drawing and the same frame in different stages such as preliminary design and construction drawing in engineering design.

[0091] Based on the same concept, the cloud service centralized drawing management platform provided in the embodiments of the present application is described in the method embodiment part.
