AI Technical Summary

Technical Problem

In the existing trainer's display and control systems, the number of codes that implement display and scheduling functions in the OFP software code accounts for about 60%, which leads to a large amount of software code debugging work required during the research and development process, with a long working cycle, many software bugs, difficult positioning, and long queries, making it difficult to quickly locate.

Method used

Agile display control mechanism is designed to summarize aerial display elements and control logic, encapsulate them into general text instructions, and write script files through text instructions to achieve control of multifunctional displays, reducing the logical calculation burden of display software.

Benefits of technology

By encapsulating the display logic in an editable PDF file, the system can easily cope with various complex display requirements changes, significantly reducing the number of software maintenance, improving software development efficiency, and simplifying the deployment and upgrade process.

Abstract

The invention belongs to the field of avionics system design, and relates to an agile display control mechanism design method implemented on a training plane. The method is realized based on an agile display control machine system, and the agile display control machine system comprises seven levels: a physical layer, a communication link layer, a window management layer, a graphic output layer, a protocol layer, a data interface module and a picture display module. According to the agile display control mechanism, picture display logic and display software are thoroughly separated, control logic is creatively added into a PDF file, and the design thought of a traditional display control system is thoroughly innovated. The innovation not only greatly improves the adaptability of the display software, but also remarkably reduces the maintenance times of the software due to demand change, thereby greatly improving the software development efficiency.
