HMI drawing method and system for aircraft simulation system

Abstract

The invention belongs to the technical field of simulation system design, and particularly relates to an HMI drawing method and system for an aircraft simulation system. The method comprises the following steps: S1, constructing a communication subclass of a currently simulated actual model by adopting QT; S2, polling the state data of the subsystems of the aircraft through a network in one cycle;and S3, driving a built-in drawing function through the state data, wherein the drawing function calls a functional area drawing function to draw an HMI function module and calls an instrument drawing function to draw an HMI instrument module, the HMI function module and the HMI instrument module are drawn in advance through a QT drawing module according to operation legend of different models, and the HMI function module and the HMI instrument module are drawn according to the operation legend of different models, and are prefabricated in a packaging library. The method and system have goodusability, universality, expansibility and cross-platform performance, can adapt to simulation requirements of various models and various battle scenes, and provide support for an air combat confrontation simulator.

Description

technical field [0001] The application belongs to the technical field of simulation system design, and in particular relates to an HMI drawing method and system for an aircraft simulation system. Background technique [0002] The drawing of the human-machine interaction interface (HMI) is an extremely important part of the aviation simulation system, and the simulation of the main human-machine interaction interface MFD, HUD, UFCP, FPD, AIP and other equipment on the aircraft is the most important part of the aviation simulation system when the air combat confrontation simulation is carried out. A function that must be implemented. [0003] Due to the different simulation tasks, the existing human-computer interaction interface drawing methods have their own defects, and their shortcomings are mainly reflected in the following aspects: [0004] The usage method is complicated. For example, OpenGL is mainly used for 3D image rendering, and the function package for 2D drawing...

AI Technical Summary

Problems solved by technology

[0004] The usage method is complicated. For example, OpenGL is mainly used for 3D image rendering, and the function package for 2D drawing function is not simplified enough; tools such as GLStudio and Vaps XT use WYSIWYG to generate drawing code, and the generated code is poor in readability and difficult to debug , the learning cost of using the tool is also high

[0005] Some tool solutions are expensive. Tools such as GLStudio and Vaps XT require commercial authorization. The authorization is expensive, and the authorization is bound to the development machine. Every additional developer needs to purchase more authorizations, which is not suitable for projects that require multiple people to develop.

[0006] Can not be cross-platform, GDIPlus and MFC drawing solutions can only be used under the Windows platform, when the software operating environment is Linux or there is a need for cross-platform, GDIPlus and MFC cannot meet the requirements; when tools such as GLStudio and Vaps XT need cross-platform, Must purchase licenses for multiple systems, resulting in more expensive prices

[0007] The data coupling with the aircraft simulator is high, and most drawing schemes are designed for specific models, directly using the ICD data on the aircraft simulator for drawing, resulting in poor system scalability

[0008] Distributed deployment is not possible. Many drawing schemes and aircraft simulators are one process, or two processes in the same machine that communicate through inter-process communication. As a result, the deployment of HMI systems is not flexible enough, and HMI cannot be integrated with aircraft simulators, Situation and other systems for distributed deployment
