The fast drawing method of a kind of colliery high voltage supply system figure

Technical field

The invention discloses the fast drawing method of a kind of colliery high voltage supply system figure.

Background technology

Also exist in the high voltage supply system figure drawing process of colliery and draw difficult and the slow problem of speed, current colliery, in the process of drawing colliery high voltage supply system figure, mainly completes the drafting to colliery high voltage supply system figure by CAD software.Drawing process is as follows:

1) some the basic drawing instruments provided by CAD software complete the drafting of relevant device pel;

2) use drawn element figure to combine the drafting of high voltage supply system figure, the Note tools such as text can be used in drawing process to mark relevant pel.

Said method is used to there are some problems, specific as follows: accompanying drawing 1 is the electric power system figure of certain colliery-200 electric substation, connection between figure mesohigh outlet switch and high-voltage terminal switch does not use connecting line, simultaneously, high-voltage terminal switch and motor or transformer are also direct connections, do not use connecting line.

direct-connected electrical equipmentimplication refer to and do not need to use connecting line and the direct electrical connection of two electrical equipments can be completed, therefore requiring between them must close alignment, otherwise just there will be mistake in follow-up high voltage supply system figure topology learning process.Therefore, the mode of artificial alignment is mainly adopted at present when drawing the electrical equipment that these needs directly connect.This will cause electric power system figure drawing process loaded down with trivial details, slow, and can because human error, causes the situation of to fail between partial high pressure outlet switch or between high-voltage terminal switch and other electrical equipment to align.

Summary of the invention

In order to solve the problems referred to above of existence, improve the drafting efficiency of colliery high voltage supply system figure and draw accuracy, the present invention proposes the fast drawing method of a kind of colliery high voltage supply system figure, concrete technical scheme is as follows.

1, picture library builds

Electrical equipment pel is built for the various electrical equipment in colliery.In the Electrical Equipments of Coal Mine pel drawn, for each pel is provided with corresponding tie point, all tie points are an all corresponding little square frame, as shown in Figure 2.When needing directly to connect between electrical equipment, need to guarantee two electrical equipments separately corresponding tie point want complete matching, as shown in Figure 3;

For often kind of pel build its picture library time, the pel original coordinate system of use as shown in Figure 4, reality draw high voltage supply system figure time, the actual drawing coordinate system of use as shown in Figure 5:

After pel is completed, the fundamental element related in pel is with XML(extend markup language) form of file preserves, the fundamental element related to and tie point element and correlation parameter are as shown in accompanying drawing 6 and accompanying drawing 7, the reference point of various element is as shown in accompanying drawing 6 and accompanying drawing 7, in pel original coordinate system, reference point coordinate calculating process is as follows: the reference point coordinate of RECTANGLE element is used represent, the reference point coordinate of WIRE element is used , the reference point coordinate of ELLIPSE element is used represent, the reference point coordinate of PIN element is used represent, then the concrete computation process of each elemental basis point coordinate is as follows:

。

2, pel reference point coordinate calculates (pel original coordinate system)

In pel original coordinate system, calculate the reference point coordinate of each element related in pel respectively, assuming that exist in pel individual element, the individual elemental basis point coordinate is used ( ) represent, pel reference point coordinate is used ( ) represent, then , .Pel reference point coordinate calculation process as shown in Figure 8.

3, pel reference point coordinate calculated examples

Pel shown in accompanying drawing 9 is the high-voltage switch gear of double lead, and there are 4 tie points, its XML file is as follows:

Be respectively for the reference point coordinate of coherent element in above-mentioned pel example:

The then reference point coordinate of this pel .

4, direct-connected electrical equipment fast drawing method

Direct-connected electrical equipment fast drawing method can complete the automatic capturing between electrical equipment, realizes the Fast Drawing of high voltage supply system figure.When having needed the direct electrical connection of two electrical equipments, when not needing again to use connecting line, use the method, the mobile equipment needing to connect, when it is near equipment to be connected, can catch tie point automatically, can realize the direct electrical connection of two equipment after confirmation, detailed process is as follows:

1) bee-line of automatically catching tie point is set ;

2) when drawing high voltage supply system figure, select certain pel, such as high-voltage terminal switch is (assuming that tie point has individual), calculate in pel original coordinate system this pel reference point coordinate ( ), assuming that in metafile individual tie point corresponding coordinate in pel original coordinate system be ( ), then this tie point in pel original coordinate system with the relative coordinate of reference point coordinate be ( ), and ;

3) start to draw this pel on drawing interface, as shown in Figure 5, the reference point location coordinate of pel is identical with the position coordinates of mouse when drawing in actual drawing coordinate system.Along with the movement of mouse, this pel is along with movement.The changing coordinates of mouse in actual drawing coordinate system is assumed to ( ), this pel tie point actual coordinate in actual drawing coordinate be ( ), then ;

4) from all tie points of this pel, a tie point be not traversed is selected , perform step 5;

5) an optional tie point be not traversed from all tie points drawing electric power system figure , the coordinate in actual drawing coordinate system be ( ), calculate it to pel tie point distance , ; If , then with tie point actual coordinate centered by coordinate draw a red small circle, prompting user captured distance join point a nearest tie point , then acquisition success, after user confirms by clicking the mouse, the coordinate of pel reference point in actual drawing coordinate system is corrected for , realize the automatic aligning of direct-connected electrical equipment, specifically as shown in accompanying drawing 10 and accompanying drawing 11; Otherwise, then step 6 is performed;

6) whether all tie points having drawn electric power system figure have all traveled through complete, if traveled through, perform step 7; Otherwise, perform step 5;

7) wait whether all tie points drawing pel travel through complete, if traveled through, then wait that drawing pel terminates at the direct-connected electrical equipment Fast Drawing of current location; Otherwise, perform step 4.
