Method and system for processing man-machine interaction event of synthetic vision system

Abstract

The invention discloses a method and a system for processing a man-machine interaction event of a synthetic vision system. The method comprises the following steps: S1, enabling a multifunctional display to send original message data; S2, converting the original message data into to-be-switched state data; S3, if the to-be-switched state data is changed relative to the current state data, generating an event, and storing the event; S4, distributing the event to a graphical interface interaction control of the multifunctional display, and enabling the graphical interface interaction control toexecute a callback function corresponding to the event and respond to the event; and S5, clearing the responded event in the event cache. According to the method and the system, the graphical interface main drawing thread or task is enabled to distribute the event in the event cache, the main drawing thread is not occupied, the event data processing efficiency is greatly improved, the reusabilityof a limited interactive element is improved, and the interface response of interactive operation is also improved.

Description

technical field [0001] The invention relates to the technical field of synthetic vision of avionics equipment, in particular to a method and system for processing human-computer interaction events of a synthetic vision system. Background technique [0002] Synthetic Vision System (SVS, Synthetic Vision System) is a new type of airborne system that uses data such as elevation terrain, map tiles, and navigation databases to generate 3D visual scenes and superimpose display speed, height, attitude, etc. The main flight parameter information image is output to the multi-function display for display, improving the pilot's situational awareness in poor visibility or complex terrain conditions. [0003] The existing synthetic vision system is mainly used to display 3D scenes and flight parameters, and there are not many human-computer interaction operations and interaction logic. Interaction and interaction logic. [0004] However, with the continuous enhancement of computer grap...

Problems solved by technology

[0004] However, with the continuous enhancement of computer graphics processing capabilities, the functions of the synthetic vision system are becoming more and more powerful. The system integrates functions such as route management, flight plan management, and system maintenance. The higher the level, the more complex the human-computer interaction logic of graphical controls

However, in order to save space in the cockpit, most of the current airborne multi-function displays have very limited interactive elements for interactive operations. How to use limited interactive elements to realize increasingly complex interactive operations and efficiently respond to interactive operations has become an urgent need. Key Issues to Solve
