Problems solved by technology

[0006] Although the 3D digital modeling of the cockpit can be realized by using the above-mentioned instrument modeling tools, there is little consideration for the modeling reusability, versatility and flexibility of important components such as instruments and controllers in the cockpit, resulting in a long design cycle , the cost is high, which brings a lot of inconvenience to the research and development work; and due to the lack of interactive functions between designers and users, it is difficult to feed back the evaluation results to the design process, which makes the designers feel powerless in the inspection and evaluation of the cockpit design layout

Embodiment Construction

[0041] The specific implementation process of the present invention includes three main steps: instrument property modeling, workflow modeling and playing tool construction. Design flow chart such as figure 1 shown.

[0042] Step 1: The system decomposes instrument properties into custom properties describing the functions of the components themselves and interaction properties describing the communication between components. Among them, custom attributes include geometric and physical attributes; interaction attributes can be further decomposed into behavioral attributes and action attributes.

[0043]The interface is the only mechanism for interaction between entities, which provides the interaction point between the entity and the external environment. Through the interface, the entity can be operated and the interaction with the outside world can be provided. As the main entity of modeling software architecture, connection also has interfaces. The interface of connection...

Abstract

The invention relates to an aircraft instrument efficient modeling design method based on components. The aircraft instrument efficient modeling design method comprises the following steps of: (1) establishing an entity component library and storing and managing various types of entity objects according to an aircraft instrument entity based on the components and a property description method; (2) structuring an instrument modeling tool based on rapid prototype and a behavioral attribute editing tool; and (3) based on a behavioral attribute simulation tool of workflow, stimulating a static model and the dynamic attribute of the static model. With the adoption of the aircraft instrument efficient modeling design method, aircraft instrument modeling can be efficiently and rapidly carried out, and the design modeling process can be rapidly realized.

Description

technical field [0001] The present invention belongs to the technical field of computer virtual reality, and specifically starts from the actual demand of developing a distributed interactive simulation system, and studies the current situation of cockpit instrument modeling technology, and develops an aviation instrument for the convenience of users to carry out entity modeling modeling design method. Background technique [0002] Aviation simulation technology develops simultaneously with the development of simulation technology and aviation industry. As an important aviation simulation device, the flight simulator has the advantages of controllability, non-destructiveness, economy, reliability, etc. compared with the actual flight test using a real aircraft, and can be used for cockpit testing on the flight simulator. Design rationality assessment. In recent years, with the rapid development of computer technology, computer-based flight simulation technology has also ma...
