A communication method for superimposed head-up display of visual system

Abstract

A communication method for superimposing a head-up display of a visual system, comprising a flight simulation system, a cabinet switch and an EPX500 visual system, wherein the flight simulation system is connected to the EPX500 visual system through the cabinet switch, and the EPX500 visual system includes a visual control computer, The visual switch is connected to the central channel computer, and the visual control computer is bidirectionally connected to the central channel computer through the visual switch; at the same time, the visual control computer is provided with a data forwarding program and a data transmission system for realizing the flight simulation system and the central channel computer. The data transmission network port establishes a dedicated data transmission channel, and uses the characteristics of the UDP point-to-point communication method to realize data transmission. The head-up display program set in the central channel computer drives the virtual head-up display to realize the superposition of the visual system; effectively reduces the head-up display. Occupying the network resources of the visual system, reducing the network burden of the visual system, and improving the real-time performance and stability of the visual system.

Description

technical field [0001] The invention relates to the technical field of flight training simulator communication, in particular to a communication method for superimposing a head-up display of a visual system. Background technique [0002] The head-up display is an important part of the avionics simulation system of the flight training simulator. It is used to provide the pilot with the most intuitive display of flight data, and the display of the head-up display is superimposed on the central channel computer of the EPX500 visual system through dynamic loading. . [0003] In the flight training simulator, the head-up display mainly communicates with the flight simulation system; at present, the communication of the head-up display adopts UDP (User Datagram Protocol) multicast communication to communicate with the simulation system, and the multicast communication The method enables the flight simulation system to communicate with HUDs on different network segments, and the H...

[0003] In the flight training simulator, the head-up display mainly communicates with the flight simulation system; at present, the communication of the head-up display adopts UDP (User Datagram Protocol) multicast communication to communicate with the simulation system, and the multicast communication The method enables the flight simulation system to communicate with HUDs on different network segments, and the HUDs can correctly receive multicast data; however, it is found through practice that the UDP multicast communication method not only occupies the network resources of the EPX500 visual system, but also increases the visual The network burden of the system affects the real-time performance of the visual system, which in turn causes network delay
