Embodiment Construction

[0032] Asynchronous communication method and synchronous communication method can be adopted in real-time communication of visual simulation.

[0033] In the process of asynchronous communication, the flight control system sends image driving instruction information to the visual system at a certain frequency. The visual system will also send image feedback command information to the flight control system at a certain frequency. At the same time, the frequency at which the visual system sends feedback commands is related to the processing capability of the display device. When the visual system processes each frame of image, the visual system first checks to get the image driving command, and then updates the image in the visual system according to the image driving command. Scene data, and finally the scene image generator completes the rendering and display work.

[0034] Because in the process of asynchronous communication, the flight control system may send the image driv...

Abstract

The invention relates to a method for visual simulation real-time communication of flight simulation training. The method comprises the following steps that a flight control system sends an image control instruction to a visual system at a certain frequency, and the visual system updates scene information after receiving the image control instruction, wherein the image control instruction comprises a flight control frame number, and when the flight control system sends the image control instruction to the visual system each time, one is added to the flight control frame number. According to the invention, with the method, the data transmission frequency of the synchronous method using the method of the invention is based on the visual synchronous display frequency, so that synchronous display of the visual data can be effectively guaranteed, the transmission efficiency of the data is improved, and the problem that the flight control end and the visual end are not synchronous due to invalid transmission of the data is avoided.

Description

technical field [0001] The invention relates to a real-time network data transmission technology based on UDP communication protocol. Background technique [0002] A real-time system is a computer system capable of performing calculations or processing functions within a deterministic time and responding to external asynchronous events. The flight simulation real-time simulation system is composed of flight control equipment, switches, and display equipment. figure 1 Shown is a schematic diagram of the flight simulation UDP network connection simulation system. [0003] During the flight simulation process, the flight control equipment outputs the status information of the aircraft and the management information of the scene. Through the technology of real-time interaction of command information, it interacts with the visual system to realize the real-time simulation of the flight process. Since a large number of different instructions need to be transmitted in real time d...
