Software platform for comprehensive display control of avionics equipment

Abstract

The invention discloses a software platform for comprehensive display control of avionics equipment, which is high in loading speed, high in graph drawing and resource rendering efficiency and capableof realizing real-time and efficient man-machine interaction and resource management. The software platform comprises a driving layer, a logic layer and a user layer, wherein the driving layer comprises a board-level support package (BSP), a data interface and a graphic interface; wherein the board-level support packet is provided with mainboard hardware and a real-time operating system and is used for interacting data with external equipment; the logic layer comprises a service logic processing unit, a data processing unit and a graph drawing engine; the data processing unit is connected with the data interface and is used for fusing the data and sending the fused data to the service logic processing unit; the graph drawing engine is connected with the graph interface and used for drawing and sending the graph to the service logic processing unit; the service logic processing unit extracts messages and events in the data according to a preset service rule and combines the messages and the events with the graph for processing; the user layer comprises a human-computer interaction interface.

Description

technical field [0001] The invention relates to the technical field of comprehensive display control of avionics equipment, in particular to a software platform for comprehensive display control of avionics equipment. Background technique [0002] Modern aircraft usually use a unified processor to uniformly process the information of various avionics equipment on the aircraft, combine devices with the same or similar functions into one component, comprehensively display relevant parameters on the display, and display them in various avionics The relevant information is transmitted through the on-board data bus, so that the performance of all avionics on the entire aircraft can reach a higher level. Such a system is called an integrated avionics system. [0003] The integrated avionics system includes a variety of equipment with many functions, such as data interface unit DIU, air data system ADC, integrated navigation system INS / GNSS, integrated radio system CNS, head-up dis...

Problems solved by technology

[0005] When the complexity of various airborne avionics equipment is getting higher and higher, and the amount of data to be processed is increasing, the software platform in the existing integrated display control unit can complete 3D navigation map display and visual synthesis, etc. When doing tasks, not only the calculation speed is slow and the delay is too large, but also the power consumption is too high, and the stability and security are low
