Description
Technical field
The present invention relates to field of computer technology, connects in particular to part model during a kind of Digitized manufacturing
Connect information retrieval method.
Background technology
In aircraft manufacturing field, Digitized manufacturing gradually instead of traditional analog quantity transmission using standard frock as foundation
Manufacture method.Manufacture is according to the project data collection for being design department's offer in Digitized manufacturing, and these project data are concentrated
Digital-to-analogue mainly reflect the geological information and technique information of part.In special part node (partnote) digital-to-analogue, deposit
Store up and the information such as the standard component used, position are connected between part, such as production division of enterprise requires that digital-to-analogue gives part
Link information, including the part of connection, the standard component used, standard component positional information etc..But in some enterprises, these information
In initial R digital-to-analogues, technologist can not only analyze the connection of part by observing digital-to-analogue for arrangement, unified representation
Relation, and the information such as standard component used, this operating process is cumbersome, and information extraction is difficult, extraction efficiency is low, it is artificial easily to go out
The problems such as mistake, while grow the technological preparation time.
The content of the invention
The existing digital-to-analogue of the technical problem to be solved in the present invention and the annexation of part are relied primarily on manually to determine, mistake
Journey is complicated, easily error, there is provided a kind of method of quick-searching connector link information.
In order to solve the above problems, the invention provides a kind of part link information search method, comprise the following steps：
Step S1, part to be retrieved and R digital-to-analogues are selected.Part to be retrieved is the object of operation, and R digital-to-analogues are that method arrow and institute are right
The information such as standard component title answered position, because part category is various on aircraft, substantial amounts, sweared with the method after intersecting
Make intersecting computing with all parts, computing is sweared than the method by whole R digital-to-analogues, time saving several times even decades of times.
Step S2, method arrow intersects computing with selection part in R digital-to-analogues, passes through the formula being given above, and exclusive method is sweared
In disjoint method arrow.
Step S3, all parts in traversal extraction product, due to using sequential operation, retrieving the link information of certain part,
It can not specifically know that the part and the part of which scope are connected, so all products corresponding to total tree are all computings
Object.
Step S4, the method for screening is sweared intersects computing respectively with all parts, by calculating, obtains all products, enters
To design pattern, the method arrow in each part and step S2 make it is intersecting calculate, obtain every method arrow corresponding to part, be as a result stored in
In array.
Step S5, arrange result data, exported by form, the information such as the part of extraction and corresponding method arrow, by concluding,
Classification, arrange, obtain part corresponding to every method arrow, if part difference corresponding to same root method arrow, "/" is used between part
Make marks, if the several part connections of identical, can count the information such as corresponding standard component title, quantity.
The advantage of the invention is that：This method can quickly calculate the letter for analyzing and being connected with selected part
Breath, including：The part name of connection, the standard component title of corresponding union piece, standard component quantity etc..
The realization of this method makes Aircraft Production process more concise quick, effectively shortens the production cycle of aircraft.

Embodiment
1-3 describes embodiments of the present invention in detail below in conjunction with the accompanying drawings：
Present example is using Visual C++ as developing instrument, on CATIA platforms, realizes the one of connector quick-searching
Kind method.
Fig. 1 is quick-searching connector information flow chart, the specific reality of quick-searching connector information proposed by the present invention
It is as follows to apply step：
Step S1, part to be retrieved and R digital-to-analogues are selected.Part to be retrieved is the object of operation, and R digital-to-analogues are that method arrow and institute are right
The information such as standard component title answered position, as shown in Fig. 2 covering 1 connects with three parts being connected with covering 2, connection
The standard component position used is exactly the method arrow 3 in R digital-to-analogues, and the information such as the type of standard component, title illustrates in R digital-to-analogues.
Because part category is various on aircraft, substantial amounts, make intersecting computings with all parts of method resultant after intersecting, than by whole
The method arrow computing of R digital-to-analogues, time saving several times even decades of times.
Step S2, method arrow intersects computing with selection part in R digital-to-analogues, and owning for standard component connection is obtained from R digital-to-analogues
Method is sweared, is obtained the array N of all method arrows, the part (L) of selection, by intersecting computing, is obtained joining (Pi), judge PiWhether
In the presence of, the intersection point being not present and method arrow are excluded, intersecting method arrow is put into former array N,
Calculation formula is as follows：Pi=FCreateIntersect[Ni, L], (1≤i≤N.Size)
Wherein N.Size is array N element number, disjoint method arrow in exclusive method arrow；
Step S3, from current operating environment, the most superior node Product1 of structure tree is found, its son is found by function
All products, these products are put into array M in level.
Step S4, the method for screening is sweared intersects computing respectively with all parts, and all methods arrow in array N is copied to array
In M each element, the part in the method resultant array M in array N intersects one by one respectively to be calculated, and excludes the intersection point being not present
And method arrow, stored each part and with the method arrow that it intersects into new array.
The recurrent formula used in calculating：
Formula is as follows：Pki=FCreateIntersect[Ni,Mk], (1≤i≤N.Size), (1≤k≤M.Size)
Wherein PkiRepresent the point that k-th of part intersects with i-th method arrow；
NiRepresent i-th method arrow；
MkRepresent k-th of part；
Step S5, arrange result data, exported by form, the information such as the part of extraction and corresponding method arrow, by concluding,
Classification, arrange, obtain part corresponding to every method arrow, if part difference corresponding to same root method arrow, "/" is used between part
Make marks, if the several part connections of identical, count the information such as corresponding standard component title, quantity.
Listed above is only the specific embodiment of the present invention.It is clear that the invention is not restricted to above example, may be used also
To there is many deformations.All changes that one of ordinary skill in the art directly can export or associate from present disclosure
Shape, it is considered as protection scope of the present invention.
