Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Along with the development of development of Mobile Internet technology and virtual reality technology, by 3G network transfer data information, use three-dimensional scenic emulation to monitor in real time operation of power networks state and be also applied to gradually in daily electric system production.As shown in Figure 1, for realizing this pressing plate, throw the electric analog system move back state simulation method and comprise mobile client module, database module and dispatching client module.Between these three modules, mutually assist, jointly complete pressing plate and throw transmission, storage and the Presentation Function that moves back status information.
On the basis of above-mentioned electric analog system, the invention provides a kind of pressing plate throwing based on virtual reality technology and move back state simulation method, comprise the steps: to adopt virtual reality technology to build pressing plate three-dimensional scenic; Detect pressing plate status information; Upgrade and preserve pressing plate status information and push; Emulation shows pressing plate status information.Below in conjunction with Fig. 2, this pressing plate throwing is moved back to state simulation method and launch detailed specific description.
First, introduce the step that adopts virtual reality technology to build pressing plate three-dimensional scenic.
In the dispatching client module of electric analog system, adopt the scene editor's subsystem editor shown in Fig. 3 to generate pressing plate three-dimensional scenic, and adopt the mode of building three-dimensional scenic of Visual Interactive, by the operation of mouse and keyboard, build pressing plate three-dimensional scenic.Scene Editor subsystem comprises model generator, 3 d model library Scene Editor and pressing plate scene library.
Model generator exports as physical equipment entity the three-dimensional model that can be used for building three-dimensional scenic by three-dimensional modeling.The secondary development environment that model generator preferably adopts 3dsmax SDK to provide, realizes the nucleus module that solid model generates; In the seamless Integrated Development Environment that is integrated into the D modeling tool 3dsmax with industrial standard of the form of plug-in unit, make solid model maker possess the editting function of powerful three-dimensional model, support to import electric three-dimensional model source data from the three-dimensional data file of various standard formats.3 d model library is used for the three-dimensional model that store and management model generator generates, and Scene Editor is used for building pressing plate three-dimensional scenic.
Visual three-dimensional picture editing machine for Scene Editor, is assembled into pressing plate three-dimensional scenic by Virtual Assembling Technology by the three-dimensional model in 3 d model library.As shown in Figure 4, the concrete steps while assembling pressing plate three-dimensional scenic are as follows: first, pick up the part needing from 3 d model library; Then, in virtual scene according to the constrained path moving parts of part (specifically referring to the multiple constraint airmanship research > > in the paper < < Integrated Virtual assembly environment of 47～52 pages of publications of < < mechanical engineering journal > > o. 11th in 2004); Then, adopt collision detection algorithm to detect part and whether bump, if bumped, in virtual scene, select different routes to re-move part, otherwise, judge whether part moves to suitable position; If part does not move to suitable position, return to continuation moving parts, otherwise, discharge part, final locating element.Collision detection algorithm adopts the cubical mode of outsourcing to realize, and wraps three-dimensional model integral body exactly with a square, travels through all apex coordinates of this three-dimensional model and obtains the current outsourcing cube that fills three-dimensional model.In virtual scene during moving parts, if the outsourcing cube of existing part occurs overlappingly in the outsourcing cube of moving parts and virtual scene, judgement bumps, otherwise, do not bump.This method has improved the efficiency of assembled, realized to a plurality of models of choosing carry out horizontal alignment, vertical alignment, level equidistantly, the function of the auxiliary assembling such as vertical equidistant and automatic adjusting size.
Secondly, introduce the step that detects pressing plate status information.
The on-the-spot inspection of the hand-held mobile client of patrol officer detects pressing plate state, obtains real pressing plate throwing and moves back status information.The scene editor's subsystem editor who deposits in mobile client generates pressing plate three-dimensional scenic.Patrol officer, by hand-held mobile client, throws according to real pressing plate the state of moving back the pressing plate state in virtual scene is set, and then pressing plate throwing is moved back to status information and sends database server to by 3G network.In order effectively to transmit pressing plate status information, each pressing plate arranges No. ID of unique correspondence, according to the status information that transmits pressing plate for No. ID.Mobile client mainly refers to deposits the pressing plate three-dimensional scenic of having put up, smart mobile phone or the panel computer that can carry out 3G communication.Mobile client module is mainly responsible for collection and the transmission that pressing plate is thrown the state that moves back.
Again, introduce the step of upgrading and preserving pressing plate status information and push.
Database server receives after the pressing plate status information that 3G network sends, and the pressing plate status information content of storage is upgraded and store, and the pressing plate status information after renewal is pushed to dispatching client.
Database module is mainly used in reception, storage, renewal and the propelling movement of pressing plate status information.Database module, from 3G network receives pressing plate status information, first can be carried out back-up storage to original pressing plate status information, facilitates follow-up management and checks; Then according to pressure plates I, upgrade the throwing of storage pressing plate for No. D and move back status information; Finally the pressing plate throwing after upgrading is moved back to status information and be pushed to dispatching client and mobile client.For cost-saving, it is MySQL database that the database server in database module preferably adopts.
Finally, introduce the step that emulation shows pressing plate status information.
Dispatching client Real-time Obtaining database server pressing plate status information also shows.
When pressing plate state changes, database server can be pushed to dispatching client the pressing plate status information after upgrading, and the data message that dispatching client pushes according to database carries out real-time update and demonstration.
In sum, the pressing plate based on virtual reality technology provided by the invention is thrown the state simulation method of moving back, and 3G network technology, database technology and virtual reality technology is applied to pressing plate and throws in the record and demonstration of the state that moves back.Utilize the present invention, can guarantee that the pressing plate throwing state that moves back transmits accurately and efficiently; Realized effective preservation of information and shared; Visual pattern ground shows pressing plate status information, makes dispatcher as if on the spot in person, accurately understands the running status of each pressing plate.
Pressing plate throwing based on virtual reality technology provided by the present invention being moved back to state simulation method above has been described in detail.For one of ordinary skill in the art, any apparent change of under the prerequisite that does not deviate from connotation of the present invention, it being done, all will form infringement of patent right of the present invention, will bear corresponding legal liabilities.
