Description
Technical field
The present invention is nuclear power and the virtual reality applications of relevant industries, more particularly to a kind of portion based on virtual reality technology
The method that part information extraction analysis is interacted with real-time emulation system.
Background technology
Virtual reality is introduced in industrialized production as a kind of means that can effectively reduce design and checking cost
Have for many years, it can just provide validation-cross possibility in the design phase of product for designer.However, every profession and trade is normal at present
In the virtual reality applications seen, browsing for model scene is only realized, and only provide simple preset interactive mode, i.e. user
It is only capable of setting up the profile of product and more intuitively recognizes, but running that can not be to product and man-machine interaction mode are carried out freely
Research.
Nuclear power plant is an extremely complex people-technology-organization system, and the quantity of its structures, system and part is very
It is huge, and be connected with each other between system and part with complicated control logic, the security and availability of nuclear power plant are safeguarded jointly.Institute
With for nuclear power industry：
1) it is far from being enough only to carry out the virtual reality applications that simple model scene browses.Three-dimensional static component mould
Type and description data (design data) are, it is necessary to real-time emulation system (design analyzer or analog machine, power plant's physics with nuclear power plant
With the numerical simulation model of control) it is associated.Designer could be in virtual reality applications by monitoring control room or just
The indicator and controller in ground region and possess dynamic operational behaviour whole power plant carry out it is interactive, in verification process also just more
Easily recognize the appearance and size and integral arrangement of structures and part in design, safety analysis, alarm/display/control characteristic,
The defect of each side such as operating standard, carries out timely design alteration and perfect.In nuclear power industry, due to its complexity, enter
The design analyzer of the extensive complicated calculations in real time of row is usually to be used as an independent system.This requires virtual reality applications
It can be effectively combined with outside computing system or computing array.
Although 2) mechanism of interaction and linkage can be developed successively in a small-sized virtual scene, for whole core
Power plant, or even only for the factory building of part, thousands of data measuring point to be separately configured often with feedback control object easily
Individual point can not possibly be completed.Simultaneously in actual engineering project, in addition it is also necessary in face of three-dimensional static component model and description
Data, and the continuous iteration more news of design analyzer difference of power plant's measurement and control logic is embodied, it is both this
The incidence relation characteristic that needs to have Auto-matching and quickly update, whole task becomes more arduous.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes what a kind of component information extraction and analysis was interacted with real-time emulation system
Method.

Need to configure the relation of the keyword mentioned and data point in drv files, the link information of analogue system, need what the cycle obtained
Data point list, the writability of data point and other for data point carry out write operation precondition.Set up the institute of Fig. 1-5.
The data analysis service shown, service from design data store and configuration service at obtain matching somebody with somebody for design document and user respectively
Put, performed successively according to data prediction flow in Fig. 2.The relational database shown in Fig. 1-7. is realized using MySQL, by number
Antistop list, footprint table, keyword and triangle end concordance list, keyword and data point relation table that Data preprocess is generated
And footprint is preserved wherein with data point relation table.
Using a design analyzer as Fig. 1-9. shown real-time emulation system, selection OPC DA2.05 are used as communication protocols
View.Fig. 1-10. shown communication transfer is set up using Python OPC to service, and selects asynchronous UDP modes to be handed over virtual reality applications
Change request and result.The shown data point cushion space of Fig. 1-(12) is set up in internal memory using circular buffering.
Corresponding emulation data man-machine interface is set up for virtual reality applications.Following several modes are used respectively,
Pattern 1：As shown in Fig. 2 based on the access of keyword, directly according to keyword query in virtual reality applications
All related data point values of certain part.
Pattern 2：It is pair that user directly chooses needs interaction in the scene as shown in Fig. 2 based on the access of solid
As, the selected object of user and gore sequence number are found by using ray detection, using object name and sequence number Fig. 1-
7. query hit polygon section in shown database, obtains related data point, carries out data query or operation.
Pattern 3：The coordinate range simulated according to current virtual practical application is from accounting in the shown database of Fig. 1-7.
All footprints included are retrieved in bit space table.Virtual collision object is set up in correspondence footprint, there is virtual reality
Collision or region of the virtual role or other studied objects of the collision system detection user of application with these occupy-place objects are touched
Hair event, is inquired about or is operated to related data point according to the triggering of event.
