Problems solved by technology

For example, how to process the wallboard is expressed through this conceptual model, study the idea of ​​process planning for aircraft structural parts, imitate the workflow of process planning by craftsmen, use this idea to establish a conceptual model, and conduct specific research in specific fields. The conceptual model description methods in the world are all expressions with data as the core, but in the field of process design of aircraft structural parts, the process method is based on the method, and the existing technology cannot solve it. Therefore, it is necessary to study a new concept model. Modeling method, expanding the description method of the original modeling method, according to the needs of this field and according to the existing knowledge characteristics, a new description method is proposed to enhance the integrity of the simulation model description, so that the simulation application is more in line with the objective reality

Embodiment Construction

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] The present invention provides a process knowledge conceptual model description method based on the user's perspective for process design of aircraft structural parts, such as figure 1 As shown in the process, the method includes the following steps:

[0031] The first step is to classify process knowledge.

[0032] The knowledge of aircraft structural parts processing technology comes from the experience of experts in the industry and actual operation and processing experience. These experiences mostly exist in the form of natural language. The knowledge points described are divided into four types of knowledge units, namely compound knowledge unit, atomic knowledge unit, attribute knowledge unit and decision knowledge unit. The knowledge units that the composite knowledge unit is further divided downwards include at least one knowledg...

Abstract

The invention discloses an aircraft structural part process design-oriented process knowledge conception model description method, and belongs to the technical field of aerospace manufacturing. The description method comprises the steps of classifying process knowledge; determining a hierarchical relationship among knowledge units; mapping the determined hierarchical relationship to an aircraft structural part processing process; and building the conception model. According to the description method, based on a view angle of a user, the return to the essence of the conception model again is realized; the process knowledge of existing aircraft structural part processing design corresponds to an actual processing scene process of a factory; a thought of aircraft structural part processing process planning is researched; technologists are imitated to perform a working process of the process planning; and a description form of the conception model is determined, so that the effect of serving as a language for realizing barrier-free communication between the user and database designers can be brought into full play, and the description method has higher practicality.

Description

technical field [0001] The invention belongs to the technical field of aerospace manufacturing, and in particular relates to a process knowledge conceptual model description method oriented to the process design field of aircraft structural parts. Background technique [0002] Conceptual model is a data model for users and the real world for the information world. It has nothing to do with DBMS (database management system) and is the first layer of abstraction from the real world to the information world. Its core is the understanding of the real world. And described, through it, realize the barrier-free communication between the user and the database designer. [0003] It is mainly used to describe the conceptual structure of a unit. Therefore, on the one hand, the conceptual model needs to have relatively strong semantic expression ability, so as to directly and conveniently express various semantic knowledge in the application; on the other hand, the conceptual model need...
