Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Fig. 1 is a flowchart of a first embodiment of the engineering drawing identification and review method of the present invention, and as shown in fig. 1, the engineering drawing identification and review method of the present embodiment specifically includes the following steps:
s101, converting the imported initial format drawing into a standard format drawing;
if the engineering drawings need to be checked, the initial format drawings need to be imported at first, and the imported initial format drawings are converted into standard format drawings, so that drawings in various formats can be checked, a user does not need to convert the drawing formats by himself, compared with the drawings in which the formats are not unified through manual checking, time-consuming cost of checking can be saved, and checking efficiency is improved. The initial format drawing may be a PDF format drawing or a picture format drawing, and the like, and the standard format drawing is preferably a CAD standard format drawing, and when the imported drawing is the initial format drawing in a PDF format or a picture format, and the like, the drawing needs to be converted into the CAD standard format drawing. If the initially imported initial format drawing is the CAD standard format drawing, the drawing is directly used as the standard format drawing without conversion.
S102, analyzing the standard format drawing, and determining a graphic object set corresponding to the standard format drawing;
after the standard format drawing is obtained, the graphs of all layers in the standard format drawing need to be analyzed, all the graphs are converted into graph objects, and the graph objects are stored in a set, so that a graph object set corresponding to the standard format drawing is obtained. The graphic objects in the graphic object set can be classified and stored according to the graphic features, for example, borders, columns, labels, and the like can be stored separately.
S103, filtering the graphic object set according to the drawing type of the drawing with the standard format by using a preset graphic filtering algorithm, and determining a graphic object set to be checked;
after the graph object set corresponding to the standard format drawing is obtained, the graph object set is filtered by using a preset graph filtering algorithm according to the drawing type of the standard format drawing, for example, graph objects such as drawing frames, axis dimension labels, north pointers, legends and the like in the graph objects can be filtered, so that interference of irrelevant verification graph objects on verification can be eliminated in the verification process, verification time consumption can be saved, and verification efficiency can be improved. The drawing types of the standard format drawing comprise a building drawing, a structural drawing, an electrical drawing, a heating and ventilation drawing, a fire fighting drawing, a water supply and drainage drawing and the like. The graph object set is filtered according to the drawing types in the filtering process. In this embodiment, the drawing type of the drawing with the standard format may be determined according to the drawing analysis, for example, the initially imported drawing is generally annotated with the type of the drawing, and the type of the drawing may be analyzed according to the imported drawing, so as to determine the drawing type corresponding to the drawing; the drawing type of the drawing can also be carried when the initial format drawing is imported, namely, the drawing type corresponding to the drawing is input when the initial format drawing is imported. After irrelevant audit graphic objects in the graphic object set are filtered, the residual graphic objects to be audited are stored in the set, and therefore the graphic object set to be audited is obtained.
S104, verifying the connection relation of all the to-be-checked graph objects in the to-be-checked graph object set according to the drawing types by using a preset graph completion algorithm to obtain automatic modification information;
after the graph objects to be checked are obtained, a preset graph completion algorithm is needed to be used for verifying the connection relation between all the graph objects to be checked in the graph object set to be checked according to the type of the graph and the design connection lines in the graph, whether the connection relation between all the graph objects to be checked is reasonable or not and whether the defects of missing pictures, random pictures and the like occur or not needs to be verified, for example, the type of the graph is a fire fighting graph, whether a restaurant fire fighting design graph is drawn, whether a missing picture door exists in a bag drawn in the design graph or not needs to be verified, whether other graph objects are drawn in a fixed distance of a fire fighting access port or not needs to be verified. If the connection relation among the graphic objects to be checked is unreasonable, the defects of missing pictures, random pictures and the like exist, and automatic modification information can be generated according to the defects. In the graph completion algorithm, different drawing types also have different graph completion rules, so in the process of verifying the connection relationship of the graph object to be checked, verification needs to be performed according to the drawing types.
S105, modifying the graphic object set to be checked according to the automatic modification information to obtain a standardized graphic object set;
after the automatic modification information is obtained, modifying the positions with defects in the connection relation between the graphic objects to be checked in the graphic object set to be checked according to the automatic modification information, so as to obtain a modified graphic object set as a standardized graphic object set.
And S106, verifying and auditing the standardized graph object set by utilizing the pre-acquired building specification library to obtain an auditing result, so that the client can acquire and display the auditing result.
And after the standardized graph object set is obtained, verifying and checking all standardized graph objects in the standardized graph object set by utilizing a pre-obtained building code library, verifying whether all standardized graph objects violate the code provisions of the state in the building industry, and obtaining a verification result, wherein when the standardized graph object set is verified and checked, verification and check are required to be carried out according to the drawing types. For example, whether the height and width of the passageway in the drawing meet the corresponding standard of the drawing type, whether a fire fighting passageway is drawn in a building, whether the arrangement of a fire extinguisher meets the standard regulations, and the like. And then sending the audit result to the client, and displaying the audit result through the client. The checking result can display the graph constructed by the standardized graph object set, highlight the part violating the standard provisions, display characters on the right side of the graph to describe which standard provisions are not met, and directly jump to the corresponding highlight graph by clicking the characters, so that a user or a checker can know the checking result more intuitively. In addition, after the auditor checks the audit result, if the graphic object violating the standard provisions is found, the client side can perform manual marking, the audit result is updated according to the manual marking, and after the auditor confirms that the audit result is correct, the updated audit result is displayed again.
In the engineering drawing identification and verification method of the embodiment, the imported initial format drawing is converted into the standard format drawing; analyzing the standard format drawing to determine a graphic object set corresponding to the standard format drawing; filtering the graph object set by using a preset graph filtering algorithm according to the drawing type of the standard format drawing, and determining the graph object set to be checked, so that graph objects which are irrelevant to checking in the drawing can be filtered, the interference of irrelevant checking graphs on checking is reduced, the time consumed for checking is reduced, and the checking efficiency is improved; by utilizing a preset graph completion algorithm, verifying the connection relation of all graph objects to be checked in the graph object set to be checked according to the type of the drawing to obtain automatic modification information, so that the efficiency of checking the connection relation of the graphs can be improved; modifying the graphic object set to be checked according to the automatic modification information to obtain a standardized graphic object set; and verifying and auditing the standardized graph object set by using a pre-acquired building standard library to obtain an auditing result, so that the client side can acquire and display the auditing result. According to the scheme, the method and the device for checking the graph drawing can be used for directly checking the imported drawing, time for checking the drawing is saved compared with manual verification and comparison, checking efficiency is improved, the subjectivity of checking can be reduced, the building specification library is directly used for checking the graph, and checking accuracy is improved.
Fig. 2 is a flowchart of a second embodiment of the engineering drawing identification and review method of the present invention, and as shown in fig. 2, the engineering drawing identification and review method of the present embodiment further describes the technical solution of the present invention in more detail on the basis of the above embodiment.

S203, filtering the graph object set according to the graph type by using a graph filtering algorithm to obtain a graph object to be checked and an irrelevant check graph object;
in this step, the specific process of filtering the graphic object set is the same as S103 shown in fig. 1, and is not described here again. After the graph object set is filtered, the filtered graph objects are irrelevant audit graph objects, and the rest graph objects are graph objects to be audited.
S204, collecting all the graphic objects to be checked to obtain a graphic object set to be checked;
through the steps, all the obtained graphic objects to be checked are collected and stored, and therefore a graphic object collection to be checked is obtained.
S205, collecting all irrelevant audit graphic objects to obtain a irrelevant audit graphic object collection;
through the steps, all the filtered irrelevant audit graphic objects are collected and stored, so that a set of irrelevant audit graphic objects is obtained.
S206, constructing a graph object set to be checked to obtain a graph to be checked;
after the graph object set to be checked is obtained, all the graph objects to be checked in the graph object set to be checked need to be reconstructed into graphs to be used as graphs to be checked. Compared with the graph presented in the standard format drawing, the graph object irrelevant to the examination in the drawing is removed.
S207, sending the graph to be checked to the client so that an auditor can determine whether the graph to be checked has an irrelevant graph;
after the graph to be checked is constructed, the graph to be checked is sent to the client, and an auditor can check the graph to be checked through the client and determine whether an irrelevant graph still exists in the graph to be checked.
S208, if the selection information sent by the auditor through the client is received, transferring the graphic object corresponding to the selection information in the graphic object set to be audited to an irrelevant audited graphic object set to form a new graphic object set to be audited and an irrelevant audited graphic object set;
after the auditor views the graph to be audited through the client, if an irrelevant graph still exists in the graph to be audited, the auditor can mark the graph to be audited, for example, click the irrelevant graph in the graph to be audited, so as to generate the selection information. If the selection information sent by the auditor through the client is received, indicating that an irrelevant graph still exists in the graph to be audited, transferring and storing the graph object corresponding to the selection information in the graph object set to be audited into the irrelevant audit graph object set, and thus obtaining the updated graph object set to be audited and the irrelevant audit graph object set.
In addition, if no irrelevant image exists in the graph to be audited after the auditor checks the graph to be audited, the auditor can confirm that the graph to be audited is correct through the client and send confirmation information. And if the confirmation information sent by the auditor through the client is received, the next step is directly executed without changing the to-be-audited graph object set and the irrelevant audit graph object set.

the execution process of this step is the same as the execution process of S104 shown in fig. 1, and is not described here again.
S211, modifying the graphic object set to be checked according to the automatic modification information to obtain a standardized graphic object set;
the execution process of this step is the same as the execution process of S105 shown in fig. 1, and is not described here again.
S212, constructing a standardized graph object set to obtain a standardized graph;
after the standardized graphic object set is obtained, all the graphic objects in the standardized graphic object set need to be reconstructed into a graphic as a standardized graphic. The standardized graph is a graph obtained by completing and modifying the connection relation between graph objects in a standard format drawing.
S213, sending the standardized graph to a client so that an auditor can determine whether the graph object connection relation in the standardized graph is qualified;
after the standardized graph is constructed, the standardized graph is sent to a client, an auditor can check the standardized graph through the client and determine whether the connection relation of the graph objects in the standardized graph is qualified, namely whether the connection relation of the graph objects is reasonable or not, and whether the defects of missed drawing, random drawing and the like exist or not.
S214, if manual modification information sent by an auditor through a client is received, modifying the connection relation of the standardized graphic objects in the standardized graphic object set according to the manual modification information to form a new standardized graphic object set;
after the auditor checks the standardized graph through the client, if the connection relation of the standardized graph objects in the standardized graph is unqualified, the auditor can label the standardized graph, for example, the connection relation of missed pictures is supplemented, the places where the pictures are wrongly drawn are modified, the places where the pictures are drawn are deleted, and the like, and manual modification information is generated according to the label of the auditor. And if manual modification information sent by an auditor through the client is received, indicating that the connection relation of the graphic objects in the standardized graphics is unqualified, modifying the connection relation of the standardized graphic objects in the standardized graphic object set according to the manual modification information, thereby obtaining a new standardized graphic object set.
In addition, if the graphic object connection relation in the standardized graphic is qualified after the auditor checks the standardized graphic, the auditor can confirm that the standardized graphic is correct through the client and send confirmation information. And if the confirmation information sent by the auditor through the client is received, the next step is directly executed without changing the standardized graphic object set.
S215, training the graph completion algorithm by using the connection relation of the standardized graph objects in the standardized graph object set, and updating the graph completion algorithm;
after the standardized graph object set is determined, the graph completion rule corresponding to the drawing type in the graph completion algorithm is trained by using the connection relation of the standardized graph objects in the standardized graph object set, and the graph completion algorithm is updated to the trained graph completion algorithm, so that the updated graph completion algorithm is used when the connection relation between the graph objects is verified and modified next time.
