Further, before obtaining target CAD engineering drawing in above-mentioned S110, this method further include:
S200: initial CAD engineering drawing is pre-processed according to naming rule is preset, obtains target CAD engineering drawing.
It should be noted that since each plan view in each CAD engineering drawing includes corresponding floor name, rightWhen each floor in target CAD engineering drawing carries out information extraction, need first to extract the floor name of each floor, then againEach information corresponding with the floor name is proposed into target CAD engineering drawing according to each floor name.For different CADEngineering drawing, the possible disunity of the rule of floor designations, thus will affect the efficiency that information extraction is carried out from CAD engineering drawing,So extract in order to more convenient to the corresponding information in target CAD engineering drawing, the present embodiment can be by pre-establishingDefault naming rule initial CAD engineering drawing corresponding for target CAD engineering drawing pre-processes, that is, will be made by CADThe engineering drawing of completion is known as initial CAD engineering drawing, and the application is first according to default naming rule to the correlation in initial CAD engineering drawingName presets naming rule according to this and modifies, and obtains the target CAD engineering drawing that related name meets default naming rule, soCorresponding information extraction is carried out according to target CAD engineering drawing again afterwards.
Specifically, the default naming rule includes the attribute names rule of the floor designations rule and PRRU in plan view.For example, floor designations rule can be with are as follows:
It for each floor is indicated with independent floor plan, the name of corresponding floor plan is with " mF is flatFace figure " indicates that such as 1 layer of corresponding plan view is named as " 1F plan view "；Basement band is then in front with " B ", such as basement oneCorresponding plan view is named as " B1F plan view "；Repeat floor plan share the outer boundary of a floor, stair boundary and itsTherefore whether elevator boundary can be to judge whether it is repetition floor according to boundary information, for the ease of from the name of plan viewNominally identify it is to repeat the corresponding plan view of floor, then also need naming standard for repeating the corresponding plan view of floor,It is indicated if it is multilayer floor with first floor, then entitled " the m-nF plan view " of corresponding plan view, such as " 4-15F planeFigure ", in the case of identical for the floor for having isolation, name form can use " 1-4,6-8F plan view ".Basement band then existsFront band " B ", such as " B3F plan view ", " B3-B1F plan view ".Wherein, name form can carry multiple commas simultaneously, such as" B3-B1F, 1F, 2-8F plan view ".
The attribute names rule of PRRU (equipment) is for example are as follows:
The attribute names standard of PRRU with " number-floor number " and indicate, the Property Name of each PRRU be it is unique,Such as " 119-1F ", wherein " 119 " indicate the corresponding number of PRRU, and the floor where " 1F " indicates this PRRU is Stall.
That is, when being pre-processed to initial CAD engineering drawing, for meeting the initial CAD work of the default naming ruleJourney figure can be directly as target CAD engineering drawing, and initial CAD engineering drawing for not meeting the default naming rule can be withThe name of each floor plan in initial CAD engineering drawing is modified accordingly according to above-mentioned default naming rule, withAnd corresponding modification is carried out to each PUUR attribute information, corresponding target CAD engineering drawing can be obtained.Wherein, name rule are presetThen it is not limited to above-mentioned specific rules, or other specific naming rules can specifically carry out according to actual needsSetting, the application do not do particular determination.
S210: target CAD engineering drawing is obtained；
S220: the attribute information of boundary information corresponding with every floor, each PRRU are extracted from target CAD engineering drawingAnd connecting line information corresponding with each PRRU；
Further, boundary information corresponding with every floor, each is extracted in above-mentioned S220 from target CAD engineering drawingThe process of PRRU attribute information and connecting line information corresponding with each PRRU, can specifically include:
Resolution process is carried out to target CAD engineering drawing according to preset decomposition rule, obtains the floor name of each floor；
It should be noted that the preset decomposition rule in the application is corresponding with default naming rule, specifically, due toIt may include repetition floor plan in each plan view in CAD engineering drawing, and marked in the title of repetition floor planPart floor number out, it is therefore desirable to target CAD engineering drawing is subjected to resolution process, to obtain the floor name of each floorClaim.
Further, above-mentioned that resolution process is carried out to target CAD engineering drawing according to preset decomposition rule, obtain each buildingThe process of layer name, can specifically include:
Obtain the current plane figure in target CAD engineering drawing；
Judge whether current plane figure is to repeat floor plan, if so, obtaining the title letter for repeating floor planBreath, and the floor name for each floor that repetition floor plan is included is obtained according to name information；If it is not, then directly acquiringThe corresponding floor name of plan view；
Using next plan view in target CAD engineering drawing as current plane figure, and returns to execution and obtain target CAD workThe step of current plane figure in journey figure, until each plan view traversal in target CAD engineering drawing finishes.
It should be noted that may include multiple plan views in target CAD engineering drawing, and it is corresponding to have plenty of single layer buildingPlan view has plenty of the corresponding plan view of repetition floor, so need to identify whether current plane figure is to repeat floor plan,If so, the corresponding each floor of the repetition floor plan can be obtained according to the name information of the repetition floor planFloor name.For example, repeating entitled " B3-B1F, 1F, the 2-8F plan view " of floor plan, then by obtaining after extraction processTo name information, " name of floor specifically can be interrupted out, for example, " B3- by B3-B1F, 1F, 2-8F " with ", " characterIt is broken into " B3-B1F ", " 1F " and " 2-8F " between B1F, 1F, 4-8F " meeting, it then again will be between the name again of floor with "-" characterIt is disconnected, due to having a variety of situations by having no progeny between first time, element be independent floor (as " 1F "), some elements are stillIt is to repeat floor (such as " B3-B1F ", " 2-8F "), therefore also need to judge each element obtained after decomposition, forIt is the corresponding element of independent floor, does not then deal with, directly acquires the floor name of the corresponding floor of the element, such as" 1F " is not processed, and directly acquires " 1F " as one layer of floor name, then can be with to the corresponding element of floor is then repeatedWith "-" character will name interruption, obtain the number of floor levels before and after "-", be supplemented the intermediate floor information lacked can obtain it is allFloor name, for example, three floors: " B3F ", " B2F " and " B1F " can be decomposited after " B3-B1F " processing；" 2-8F " can be decomposedSeven floors out: " 2F ", " 3F " ..., " 8F "；So as to obtain and repeat floor plan " B3-B1F, 1F, 2-8F planeThe corresponding each individual floor name of floor of figure ": " B3F ", " B2F ", " B1F ", " 1F ", " 2F ", " 3F " ..., " 8F ".
If current plane figure is the corresponding plan view of independent floor, the corresponding floor name of plan view is directly acquired i.e.It can.The usual above method traverses each of target CAD engineering drawing plan view, and obtains and institute in each plan viewIncluding the corresponding floor name of each floor, and then obtain the floor name of every floor pair in target CAD engineering drawing.
Each floor name is matched with target CAD engineering drawing, obtains boundary letter corresponding with each floor nameThe attribute information of breath and each PRRU；Attribute information includes PRRU number and floor name；
After the floor name for obtaining each floor, each floor name is matched with target CAD engineering drawing, energyIt accesses and the attribute information of the corresponding boundary information of each floor name and PRRU corresponding with each floor, that is, logicalIt crosses floor name and matches plan view portion corresponding with the floor name from each plan view in target CAD engineering drawing,According to and the corresponding plan view portion of the floor name extracts the boundary information of the floor and PRRU corresponding with the floor belongs toProperty information.
The attribute information of each PRRU is matched with target CDA engineering drawing, obtains connection corresponding with each PRRULine information.
After the attribute information for obtaining each PRRU in every floor, can according in the attribute information floor name andPRRU number, matched into target CAD engineering drawing, match plan view corresponding with the floor name, then further according toPRRU number matches the specifying information that corresponding PRRU is numbered with the PRRU, including connecting line information from the plan view.
Specifically, the boundary information in the application includes outer boundary coordinate information, elevator boundary coordinate information and stairCourtyard boundary coordinate information；Connecting line information includes connecting line coordinate information.
It is understood that when the connecting line information of boundary information and each PRRU to every floor extracts, byMulti-line section is belonged in CAD engineering drawing in boundary line and connecting line, each break of multi-line section has corresponding in CADAbsolute value coordinate, so the boundary information in the application includes the corresponding coordinate information in each boundary, for example, outer boundary coordinate is believedBreath includes the corresponding coordinate information of each break in the boundary line of outside, and elevator boundary coordinate information includes each on elevator boundary lineThe corresponding coordinate information of a break, stair courtyard boundary coordinate information includes that each break on stair courtyard boundary line is correspondingCoordinate information, connecting line information includes the corresponding coordinate information of each break on connecting line, according to each in each boundary lineThe coordinate information of a break can draw out the boundary line.
Specifically, in CAD engineering drawing, all floor plans be all fasten expression in an absolute coordinate, namelyThe corresponding absolute value coordinate of each break in the multi-line section of each boundary line, due in three dimensions, being built for oneStall and second floor take identical position three-dimensional coordinate (x, y, z) should be z coordinate difference, x and y coordinates are identical.ButIt is that, since the floor in CAD engineering drawing all provides in plan view, z coordinate can not obtain, it is possible to obtainThe coordinate taken is also two-dimentional (only x and y), and z coordinate can voluntarily give according to the actual situation in visualized three-dimensional graphic.
But in CAD engineering drawing, it is absolute coordinate that Stall and second floor, which take the corresponding coordinate in identical position just different,So the coordinate of each break can be indicated accurately, the relative coordinate of each break can be extracted in the application, such as can be withIt is also absolutely to sit in CAD that an identical location point x1 and y1, x1 and y1 are selected in the corresponding plan view of each floorMark, therefore, the relative coordinate Δ x of each floor information may be expressed as: Δ x=x1-x, Δ y=y1-y, using relative coordinate tableThe coordinate information for showing each break on boundary line can make the coordinate letter of the identical position x and y having the same of different floorsBreath.
S230: according to and the corresponding boundary information of every floor, the attribute information of each PRRU and corresponding with each PRRUConnecting line information generates corresponding visualized three-dimensional graphic.
Further, in the category for extracting boundary information corresponding with every floor, each PRRU from target CAD engineering drawingAfter property information and connecting line information corresponding with each PRRU, further includes:
According to GML pairs of geographical graphic markup language boundary information corresponding with every floor, each PRRU attribute information andConnecting line information corresponding with each PRRU is handled, and obtains meeting GML linguistic norm, corresponding with every floor each sideBoundary's information, the attribute information of each PRRU and connecting line information corresponding with each PRRU；
It should be noted that the information extracting method of the CAD engineering drawing in the application can using based on ObjectARX andThe software realization that VS2008 writes, and can using based on WebGL3D drawing agreement according to the boundary information that extracts and respectivelyThe attribute information of a PRRU and connecting line information corresponding with each PRRU generate visualized three-dimensional graphic, wherein due to being based onThe data that ObjectARX and VS2008 are extracted can not directly be read based on WebGL3D drawing agreement, it is possible to logicalIt crosses geographical graphic markup language GML and GML standardization processing is carried out to the information of extraction, namely sampling GML language description is extractedThe corresponding boundary information of floor arrive and every, the attribute information of each PRRU and connecting line information corresponding with each PRRU, makeExtracted information meets GML linguistic norm.
Then, above-mentioned foundation boundary information corresponding with every floor, the attribute information of each PRRU and corresponding with each PRRUConnecting line information generate the process of corresponding visualized three-dimensional graphic, be specifically as follows:
Using based on WebGL3D drawing agreement to meet GML linguistic norm, corresponding with every floor each boundary believesBreath, the attribute information of each PRRU and connecting line information corresponding with each PRRU carry out visualization processing, obtain accordingly may be usedDepending on changing 3-D graphic.
