Problems solved by technology

In many UA systems, some UA screens (Screen A) are relatively simple, and the display drawing time is relatively short, such as 1 time unit, while some UA screens (Screen B) are more complicated, and the display drawing time is longer. For example, 3 time units, when CDS integrates display, no matter for screen A or screen B, the performance overhead is 4 time units, which invisibly reduces the performance of screen A, which has higher real-time requirements.

Abstract

The invention belongs to the technical field of integrated avionics system design, relating to a multi-CDS instance integrated high-performance cabin display system based on ARINC661. The system comprises a partition operation system module, a configuration file display module, an IO communication module, a CDS software module, a window management module and a display scheduling module. The partition operation system module is used for providing a plurality of independent physically isolated partitions for an integrated platform of the cabin display system, different CDS instances run in different partitions, and each CDS instance calls different display configuration files and finally displays the display configuration files through the display scheduling module and the window managementmodule. According to the system, a plurality of CDS instances are operated in a plurality of partitions on a partition operation system, different UA layers are drawn in different areas on a physicaldisplay. Different drawing frequencies are completed in different display areas, and the overall display performance of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of comprehensive avionics system design, in particular to a high-performance cockpit display system integrated with multiple CDS instances based on ARINC661. Background technique [0002] With the continuous improvement of the integration of avionics systems and the continuous improvement of the requirements for human-computer interaction, the cockpit display system is also developing towards an open architecture. The ARINC661 specification divides the cockpit display system into UA (UserApplication, UA for short) and CDS ( Cockpit Display System (CDS for short) two functional modules, aiming to completely isolate the display function and logic processing function of the interface, and improve the openness and portability of the display system. A complex cockpit display system integrates multiple UA subsystems. All UA system parameters need to be comprehensively displayed on one display. In the existing disp...
