Abstract

The invention provides a naming method for complex system characteristics. A machine assembly formulates and selects the standard and uniform templates according to the requirements, issues the templates to multiple development organizations including an assembly, a structure and mechanism subsystem, a thermal control subsystem, other subsystems, the process design department and the like, and issues the templates to related single-machine units through all collaborative units. For space vehicles, the machine assembly plans and formulates interface classifications of a three-dimensional model on the basis of characteristics of three-dimensional model characteristic transitional information and through combination with the characteristic classifications. The machine assembly formulates interface standards for the related collaborative units, and the characteristic naming method achieved after characteristic expression is adopted for standard interface information.

Description

A kind of control method of data-interface

Technical field

The invention belongs to spacecraft three-dimensional digital field, be specifically related to a kind of control naming method of data-interface.

Background technology

The design of spacecraft and development exist that functional requirement is more and more, the interface relationship between system becomes increasingly complex, designing quality is required to more and more high.Take at present three-dimensional digital collaborative design means to solve design and the development demand that adapts to spacecraft.A plurality of research institutes such as the collaborative design of spacecraft three-dimensional digital participates in that unit comprises that machinery is overall, structure and machinery subsystem, thermal control subsystem and other subsystems and technological design department, the data-interface relation between collaborative unit is complicated.Simultaneously in Process in Cooperative Design, the version relating to is various, mainly comprise spacecraft configuation model, pipeline model, cable model, interior trim model, ventilation model, connector model (pipe adapter, electric connector, ground stud etc.), securing member model, stand-alone device model etc., the data-interface relation between variety classes model is staggered numerous and diverse.The state of current spacecraft data-interface is controlled the following problem that exists:

It is many that the collaborative design of spacecraft three-dimensional digital participates in unit, and between commensurate, the input/output relation between model is not complicated.Meanwhile, the model of each collaborative unit is along with model development gos deep into and constantly perfect, and constantly improving in process of model, the interface data of model is also being constantly updated.The renewal of the superior and the subordinate unit's model interface data need to, by manually going assurance and completing, cause that designer's workload significantly increases thus.Meanwhile, because people's mechanization participates in the transmittance process of data, cause the inconsistent of the superior and the subordinate's model data interface, and easily introduce low staging error;

When superior unit model dynamically updates, the input interface data of subordinate unit's model cannot be upgraded automatically thereupon, the recent design state of superior unit model cannot be passed to subordinate unit, and data-interface transmission causes rudimentary design mistake continuously, and designing quality also cannot be guaranteed.

Because the data-interface between the superior and the subordinate unit's model cannot be realized robotization, upgrade and transmit, causing interface data state in whole design process accurately to be controlled.

In whole Process in Cooperative Design, the version existing in the model of same unit is various, also has complicated input/output relation between inhomogeneity model.The various generation that also can cause the problems referred to above of version.

Summary of the invention

The technical matters that the present invention solves is the control method that proposes a kind of data-interface, by setting up the automation data correlating method between the superior and the subordinate's model, avoid in the superior and the subordinate's model interface data transfer because low staging error is introduced in people's participation, evade the inconsistent phenomenon of spacecraft the superior and the subordinate model interface data in the past, realize correctness and the validity of in Process in Cooperative Design, inputting data source header, and realize upgrading in time of information in whole Process in Cooperative Design, guarantee the three-dimensional collaborative design quality of spacecraft, form effective state of the art control method, comprise the steps:

1) machinery is totally formulated the unified template of selection standard according to demand, is handed down to a plurality of research institutes such as overall, structure and machinery subsystem, thermal control subsystem, other subsystems and technological design department, and is issued to by each collaborative unit the unit unit that is correlated with;

2) feature based on three-dimensional model features convey information for spacecraft, each collaborative unit is expressed with the form of feature total interface data in three-dimensional model;

3) higher level's model forms the packing of output interface data the packet of issue;

4) subordinate's model is realized the dynamic auto association of the superior and the subordinate's model interface data by copying the interface data bag of higher level's Model publish;

5), during higher level's model interface Data Update, by refreshing, can realize the input data of correlation model and upgrade thereupon.

The method applied in the present invention, higher level's model, by output interface data are packed, is opened output data and other data separating, realizes in three-dimensional model the paying close attention to of output interface data, and guarantees to export effective control of data mode; Subordinate's model, by the copying of higher level's model interface data, has been avoided human factor in data transfer to introduce low staging error, and has been realized the auto-associating of IO interface data; During higher level's model modification, by refresh operation, guarantee that the mode input data that are associated upgrade in time, guaranteed designing quality, realized effective control of interface data state in whole design process.

Embodiment

Below the present invention is further illustrated:

Machinery is totally formulated standard form according to demand, is handed down to each collaborative unit, comprises the acquiescence characteristic informations such as point, coordinate system, reference planes, axle, curved surface in standard form;

Machinery is the feature based on three-dimensional model feature interface data for spacecraft totally, in conjunction with tagsort, each class interface is expressed with the definition of different characteristic, refers to table 1.

Table 1 spacecraft model system three-dimensional model feature name summary sheet

Higher level's model is issued after output interface data are packaged into packet, and subordinate's model is by copying the interface data bag realization of higher level's Model publish and the auto-associating of higher level's model interface data;

Carrying out on the basis of above three steps, carrying out three-dimensional digital collaborative design, realizing effective control of interface data state in whole design process.

In the present invention, undeclared part belongs to the known technology of this area.

Finally it should be noted that: above embodiment apply to illustrate the present invention and and unrestricted technical scheme described in the invention; Therefore, although this instructions has been described in detail the present invention with reference to each above-mentioned embodiment, those of ordinary skill in the art should be appreciated that still can be to the present invention modify or be equal to replacement; And all do not depart from technical scheme and the improvement thereof of the spirit and scope of invention, it all should be encompassed in the middle of claim scope of the present invention.
