Problems solved by technology

However, domestic 3D simulation tool software dedicated to aerospace missions is not abundant, and most of them are derived from GIS systems. It is more than enough to meet the needs of geographic information display during the aerospace process, but it is difficult to meet various key elements in the rocket flight process. Co-simulation requirements, especially factors such as flight trajectory, rocket body attitude, key actions, etc. cannot be coordinated, and there is no mature software method model for space launch missions

Embodiment Construction

[0019] Taking four basic modules as an example, the implementation steps of the method are described below:

[0020] 1. Construct a geographical image data source based on quadtree hierarchical cutting, and create a 3D scene based on this, and build a basic environment module for 3D simulation.

[0021] 2. Build a model analysis and control module to realize the reading of 3D scenes, component analysis and action control of time-related modules, and provide a list of movement modes of time-related modules by reading configuration files to register the time information of the scene The method automatically controls the key actions of the time-dependent modules.

Abstract

The invention discloses an observer mode based space launching task three-dimensional graphic simulation method. According to the method, all time-related objects in a launching process are taken as observers, variables in a time system are taken as observed objects, and when the observed objects are changed, the observers adjust self states according to the changes. A geographic image data source based on quadtree layered cutting is constructed, a three-dimensional scene is created based on the geographic image data source, a model analysis and control module and a time system module are constructed, and a trajectory data driver module converts position and speed information in trajectory data into the position and state of a rocket in the three-dimensional scene through registration time information of the trajectory data. The weak coupling of a plurality of simulation object entities is realized and the mutual interference risk of simulation objects is lowered. The method can perform scientific, accurate and easily understood spatial graphic simulation on various parameters in space launching, and has relatively high timeliness and expandability.

Description

technical field [0001] The invention relates to the field of three-dimensional graphics simulation, in particular to the simulation of the rocket flight process in the space launch mission, and is applicable to the whole process from the ignition of the rocket to the separation of the satellite rocket. Background technique [0002] It is an important development trend in the field of aerospace measurement and control to use 3D graphics simulation to display the flight status of the launch vehicle in space launch missions, and then complete the visual display of abstract measurement data. However, domestic 3D simulation tool software dedicated to aerospace missions is not abundant, and most of them are derived from GIS systems. It is more than enough to meet the needs of geographic information display during the aerospace process, but it is difficult to meet various key elements in the rocket flight process. Co-simulation requirements, in particular, factors such as flight tr...
