Description
Technical field
The present invention relates to the online checking method and system of a kind of engineering drawing, more particularly to preserved in the way of electronic document
Engineering drawing online checking method and system, further, be directed to use with CAD graphics softwares generation engineering drawing it is online
Checking method and system.
Background technology
In the design process of engineering drawing, each side for participating in cooperation needs suggestion of the frequent exchange to layout design details.
Such as：School in specialty is examined, audits, authorization link；The mutual drop handle section of data between specialty；Designer is existing with construction party discussion construction
Problem that field finds etc..In order to accurately express the suggestion to local design details, there is following several method at present：
First, traditional way, prints engineering drawing, local detail problem is irised out with pen come then on drawing
Freehand brushwork aside is shown in.This mode is simple and reliable, but there is also a series of problem：
（1）Paper is wasted relatively.Because the discussion to details, an often process trifling, constantly repeatedly, drawing
Limited space, can not directly display amended result, and this is accomplished by the e-file for constantly changing engineering drawing, Ran Houzai
Print, then examination ＆ verification, discussion again.
（2）Information transfer efficiency is than relatively low.The communication of most extreme example, construction party and designer, need through
Print drawing, fill in several links such as suggestion, postal delivery drawing.Generally these suggestions are crime scene discussion exchanges, but with
The increasing of design objective, the increase of job location distance, exchange not at the scene are also more and more.This traditional way, more
To get over the needs that can not meet fast pace engineering development.
（3）The information of review process cannot be re-used.Design industry progressively carries out quality management at present, needs to institute
There is design process all to be recorded.The suggestion that process is produced is examined in drawing school, if being entirely to write on drawing, is also needed to again
These suggestions are filled up in the quality list of correlation again, this undoubtedly increased the work load of related personnel.In practical work
In, project progress is often given priority to, quality formfile is later supplemented with, these procedural informations being supplemented with later, just
Cannot ensure accurate, complete.
2nd, electronic meeting.With the development of network technology, if the discussion both sides of engineering drawing are not in one place, can be with
The purpose of exchange suggestion is reached by electronic meeting.Electronic meeting provides one virtual " electronic whiteboard " so that participation is begged for
By each side the image of correlation can be seen by the video shared, if one party needs to propose to anticipate the modification of details
See, can write down on electronic whiteboard.The exchange efficiency comparison of this method is high, suggestion can be conveyed to correlation in real time
Personnel.Have the disadvantage that the suggestion filled in is difficult to preserve, also cannot accurately combine with engineering drawing.Write on electronic whiteboard
The suggestion come often can only be preserved with picture format, but engineering drawing is polar plot, in software can be with arbitrarily enlarged and diminution.This
Allow for suggestions made after examination and engineering drawing can not be superimposed well, difficulty is brought to access.In addition, electronic meeting is frequent
Transmission video image gives conference participation each side, very high to network bandwidth requirement, also limit its use.
3rd, directly change e-file.In practice, approving person often directly fills in suggestion on e-file,
Relevant design personnel are sent to after preservation.Due to being that, in same file, suggestion and engineering drawing just can be stacked up well,
Annotation part can not also be shown as needed, it is also possible to is printed and is further checked.The shortcoming of this method is to change
The integrality and reliability of drawing, because revisions on drawings means that to be possible to bring other to change, brings difficulty to management.One
As in the case of drawing can only be modified by designer, other staff can only provide suggestion for revision.And if other staff also can
Revisions on drawings, then need supporting edition control method, just can guarantee that will not there is several individuals while changing same engineering drawing
E-file.Even if having accomplished this point, the integrality of drawing is remained has very big risk, because engineering drawing is often very multiple
Miscellaneous, it is a more complicated process that CAD software preserves the process of engineering map file, as long as there is modification, it is possible to bring other
Unknown change.
4th, it is the general annotation work for browsing file format such as DWF, PDF etc., then reusing correlation graphic exchanging
Tool, fill in suggestion browsing in file.This mode does not change original engineering drawing, therefore can ensure that engineering drawing e-file
Integrality and reliability, annotation suggestion also can stack up with engineering drawing well.Which primary disadvantage is that to be converted to and browses
The process of file format wastes time and energy, and compares impact efficiency.Especially in the case where needing frequently to modify and audit, this
Plant impact of the method to efficiency just to become apparent from.In addition, designer is directed to suggestion for revision, original engineering drawing to be opened, again
Positioned, be further continued for modification, also not enough facilitate.
The content of the invention
It is an object of the invention to overcome the various problems that existing engineering drawing checking method is run in real work, propose

Specific embodiment
In order that the purpose of the present invention, technical scheme, beneficial effect become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is described in further details to the present invention.It should be appreciated that specific embodiment described herein is used only for explaining this
It is bright, it is not intended to limit the present invention.
It is described in detail below in conjunction with realization of the drawings and specific embodiments to the present invention：
The present invention takes the method for increasing plug-in unit in CAD software, design the review process and engineering drawing of engineering drawing,
Running environment is combined closely so that auditor can efficiently exchange suggestion with designer, while keeping the integrality of drawing.
Although with the difference of CAD software, plug-in unit is also required to do corresponding change, the form of the annotation that review process is produced, annotation
The links such as the combination of the Overlapping display of suggestion, the transmission for annotating suggestion, annotation suggestion and quality list, principle are just as, only
The method for needing to show annotation for different CAD software changes, therefore can be easy to expand to other CAD softwares.
As shown in figure 1, the method that the engineering drawing of the present invention is audited online is comprised the following steps：
The first step, annotates instrument used in engineering drawing, and the annotation including annotation position, annotation suggestion for recording user is joined
Number.
The annotation parameter of user record is needed to include：Annotation type, annotation position, annotation color, annotation suggestion, annotation are closed
The pel of connection, performance rating type.
Annotation type includes：Rectangle, circle, ellipse, cloud line.
Rectangle：The coordinate in the upper left corner and the lower right corner in rectangle annotation region.
It is circular：The circular coordinate and radius in circular annotation region.
It is oval：The extreme coordinates of the major axis and short axle in oval annotation region.
Cloud line：Each extreme coordinates of one polygonal region.
The location parameter of annotation depends on annotation type.
The pel of annotation association can be selected in the e-file of engineering drawing by user, used as the foundation for referring to from now on.
If annotation is associated with pel, relative to annotation scope is simply used, can accomplish more accurately to position.
Performance rating type is relevant with designing unit specific performance rating system, can be some alternative words
Description or numerical value.
Second step, splits to the picture frame scope of the engineering drawing, recognizes the whole figures included in the engineering drawing
Frame scope, reads the corresponding title block content of the picture frame scope, the annotation position is compared with whole picture frame scopes
It is right, it is determined that the picture frame scope belonging to annotation, is associated the annotation suggestion with affiliated picture frame scope and its title block content.
The Main Function of the step is to identify picture frame scope and corresponding title block content that engineering drawing included, will
The location parameter of annotation is carried out contrasting with picture frame scope, is associated, and determines an annotation belongs to which picture frame and title block.
3rd step, the annotation parameter is stored in the annotation file being associated with the engineering drawing.
Annotation file can be preserved according to general XML format, and with engineering drawing file association together.Modification every time is annotated
When, annotation file is all preserved again.The medium that annotation file will be transmitted in system as annotation, no matter engineering drawing is placed on
Where, annotation can be opened at any time and be checked.
4th step, reads the annotation parameter in the annotation file, by the annotation suggestion in the annotation parameter according to batch
Note type is converted to pel and is added in the engineering drawing temporarily.
The information of annotation parameter is read out first from annotation file, then annotation is converted to according to annotation type
Different pels, is added in current engineering drawing temporarily, and so annotation just can be shown with engineering drawing together, and with engineering drawing
The change of state and change.After closing annotation display, the annotation for being added to engineering drawing temporarily is all cancelled, it is ensured that engineering drawing electronics
File is not modified.
The annotation file is sent to other online users by the 5th step, and other online users receive the annotation text
After part, the annotation parameter in the annotation file is read simultaneously by annotation simultaneous display on same engineering drawing.So can be to working as
Front user's online modification drawing plays directive function.
Also include the 6th step after 5th step：To include that annotation author, annotation suggestion, annotation scope, annotation are associated
The annotation content of pel and picture frame scope is stored in database, formulates template file, and the specified data in extracted data storehouse are filled out
Quality list is generated in template file.
Quality list can be preserved by way of HTML or other texts, added in the specified location of file
Label, determines each grid in quality list needs what content filled in.Annotation content is stored in database, including annotation is made
Person, annotation content, annotation time, annotation scope, the pel of annotation association and picture frame scope etc..By set up annotation content and its
Its data-base content is contacted with quality list, such as one database store process, it is possible to represent quality list when
Wait, annotation content Auto-writing in quality list, quality list is rewritten afterwards so as to reduce project planner
Workload.
In order to directly display annotation when engineering drawing is opened in CAD software, the present invention set up three kinds of states：Normally
State, browse state, editing mode.Normal condition refers to the state drawn by CAD software；Browse state refers to Overlapping display
The state of annotation suggestion；Editing mode refers to the state for drawing annotation.Under editing mode, the input of user is to draw in fact
Annotation.The annotation type that system is selected according to user, the input user in CAD software resolve to different operations, such as draw
Straight line, picture circle, picture cloud line, input word etc..The now input of user is controlled, and resulting pel is not really to add
The pel being added in system, but be converted to special endorsement information temporarily and saved.After editing mode terminates, automatically
Into browse state, system is converted to specific pel endorsement information and is added on engineering drawing temporarily, but real change
Engineering drawing.Under this state, user zooms in and out to drawing, translates, operation is checked in page turning etc., annotate as pel also can and work
The other parts of journey figure are equally moved, therefore the effect for browsing is exactly the annotation that user is shown in engineering drawing laminated thereto
Suggestion.End is browsed, system is all withdrawn the operation of addition annotation pel before automatically, and drawing does not still do any repairing
Change, this has just been effectively ensured the integrality of drawing.User directly can also be switched to browse state from normal condition.Browsing shape
Under state, system is selectively converted to pel some annotations, is added to current engineering drawing temporarily, but all of mapping operation is all
It is prohibited, if user have selected any mapping operation, system is switched to normal condition, and closes the display of annotation, prevents
Annotation is incorporated into into current engineering drawing only.Under browse state, user clicks on any one annotation, and system is just the display of engineering drawing
Region is switched to annotation region, facilitates user quickly to check and position.
Another benefit that the design environment of review process and engineering drawing is combined closely is that user has checked annotation meaning
See, it is possible to start at once to modify, and without the need for toggling in multiple environment.And, current engineering drawing institute is in place
Put, be accurately positioned because annotation is checked.The loss of so operating efficiency is just much smaller than alternate manner.
In addition, the annotation suggestion produced in review process, comprising many information.Existing checking method typically can only
The suggestion of record user input, and user name, time etc., the actual content efficient association of annotation and engineering drawing can't be risen
Come.And need in these information exactly quality management system.Therefore in order to pass through quality review, engineering staff has in matter
These annotation suggestions and the corresponding Engineering Drawing Information of annotation are re-typed in scale list, the duplication of labour is thus caused, also band
The possibility slipped up is carried out.The present invention combines closely the running environment of review process and engineering drawing, is drawing annotation
Process, it is possible to the engineering drawing content of Direct Analysis relevant range, so as to annotation and specific engineering drawing content are associated,
The picture frame of such as engineering drawing, title block.The drawing of all formal printings, has a rectangle frame as sideline, and this sideline is referred to as
" picture frame ".In a corner of picture frame, there is a description form, record the important engineering information of drawing, such as engineering name, figure
Name, figure number, designer etc., referred to as " title block ", as shown in Figure 4.By annotation scope and picture frame scope are associated, just very
Which specific engineering drawing clear annotation acts on,.Specific way is, in user input after annotation scope, first to work
The picture frame scope of journey figure is split, it is determined which picture frame scope annotation falls in.Then the title block content in the picture frame is entered
Row analysis, finds out the engineering attribute of the picture frame：Engineering name, job number, the map title, figure number etc..So, annotation just can and these
Specific engineering information is associated together.
As shown in Fig. 2 the method for splitting picture frame is as follows：
All of straight line information in 1st step, the reading engineering drawing, filters out horizontal and vertical straight line and according to straight line
Length is ranked up.
2nd step, the most long straight line A of length is found out, circulation is found out
A vertical straight line B and straight line C.
The most long straight line of length is found out, if a plurality of, one is arbitrarily taken, straight line A is designated, circulation is found out and the straight line
Two summits of A are adjacent, and the vertical straight line in direction, are designated straight line B and straight line C.
3rd step, the straight line D for finding out end points on the connection straight line B and straight line C away from straight line A one end, straight line A, straight line
B, straight line C and straight line D-shaped are rectangular.
Straight line that is vertical with straight line C with straight line B and connecting is found out, straight line D is designated, straight line A, straight line B, straight line C and straight
Line D-shaped is rectangular.If can not find, straight line B and straight line C is continually looked for.If all can not find, straight line A is abandoned；
Straight line B, C are it is determined that just can determine that after straight line A, therefore just abandon straight line A while abandoning straight line B and C,
However it is necessary that repeating step 2.
Whether the 4th step, the analysis rectangle meet picture frame standard, if the rectangle meets picture frame standard, by the square
During shape is saved in split database and will all other straight line included with the rectangle intersection or by the rectangle from queue all
Delete.
If rectangle have found, just check whether the rectangle meets the standard of picture frame.If the rectangle meets picture frame standard,
Then it is saved in split result, then all other straight line included with the rectangle intersection or by the rectangle from queue
All remove；
The criterion of picture frame is：Firstth, comprising specific title block word, such as：Engineering name, examination ＆ verification, authorization etc.；Secondth,
In the rectangle, there is one to compare the interior rectangle frame pressed close to.
Picture frame specifically judges that step is：A1, set feature word, the area ratio of interior housing that each class picture frame is included
Example scope；A2, it is all fall word in the rectangular extent find out and be compared with feature word one by one, if a3,
Step a2 passes through, then all straight lines being included in the rectangular extent are screened, the 2nd the-the 3 step of step of repeat step, finds
One maximum rectangle frame being included in the rectangle, then calculates its area, the maximum rectangle frame of gained and former rectangle frame
Area is compared and obtains a ratio, judges whether the ratio falls in the range of setting.
5th step：The most long straight line of length in remaining straight line is read, the 2nd step of repeat step is to the 4th step, until traversal is all
Straight line.
From the remaining straight line of rectilinear alignments, the maximum straight line of length is taken, repeats above action, until traversal is all of straight
Line.
After splitting to the picture frame scope of engineering drawing, the coordinate range of the picture frame of gained has determined, and adds
When annotation, the coordinate range of the minimum rectangle comprising the annotation can also be equally obtained.Picture frame as obtained by comparing with
Coordinate range comprising the annotation minimum rectangle, it is determined which picture frame scope annotation falls in.If comprising annotation minimum rectangle
Coordinate range intersect with the coordinate range of a picture frame of gained, determine that annotation falls in this picture frame of gained.For
The picture frame for splitting out, starts title block identification module, can be the correlation engineering acquisition of information in picture frame out.Concrete title block is known
The method of the identification title block in other module is disclosed by 200810216795.4 patents, and here is not being repeated.
The annotation suggestion that user is formed in review process, is saved down the part for being used as design process information.Setting
In the quality management system of meter industry, needs are all recorded to all design processes, are examined process including engineering drawing school and are produced
Raw document.The present invention can also annotation suggestion and correlation engineering information, the list form specified according to user, automatically
Related e-file is generated, so as to avoid the tedious work amount of project planner's gap filling macadam list afterwards.Such as Fig. 3 institutes
Show, the generating process of quality list is as follows：
1. template file is formulated according to the form of quality list
The electrical form of html format is drawn according to quality table single lattice formula, and the domain of correlation is set in electrical form

The input domain defined parameters of list, specifically include：
（1）The title of input domain
（2）The size of input domain
（3）The corresponding control of input domain, such as text box, combobox, multiline text frame, date
（4）The corresponding DSN of input domain
The storing process title that list is used.In order to be able to process various types of list forms, need 4 kinds of definition different
Storing process, effect is respectively：
（1）Obtain the content of general text type input domain
（2）Obtain the content of the input domain for needing user to select in a list
（3）Obtain the content of a detailed form
（4）Obtain the authority of an input domain
2. determine the data source of information in template file, marked in a template
3. the call relation and parametric form of template file and database store process are determined
Storing process refers to the program for being stored in database, can realize the operation flow of user according to actual needs.This
In need the number of parameters and type of storing process that definite quality list uses, so prepare to obtain list number in operation system
According to when, can be according to the parameter of agreement calling storing process.
4. after generating the command triggers of quality list, the information of automatic data collection Current software running environment, including：Current work
