Problems solved by technology

If purely transplanting the ARINC661 specification originated from the display and control system of the civil aircraft cockpit, using the calling method of the target symbol in the specification will not only increase the workload of the developer, but also increase the memory requirements of the CDS kernel, affecting the performance of the display and control system

Abstract

The invention discloses a display control method of cockpit display control system aiming symbols. The display control method for tedious and redundant warplane aiming symbols is designed on the basis of ARINC661 standards and the open and expandable features of the standards by performing adaptive modification on part of concepts and the application method of the standards, and accordingly the ARINC661 standards can be efficiently and reliably applied to a warplane cockpit display control system. The display control method achieves the display control of the complex and tedious aiming symbols of the cockpit display control system by designing a user-defined window part MapHorzItemListPlus / MapVertItemlistPlus, a user-defined display item Symbol_Compound and a user-defined interactive display item Symbol_Compound_Interactive and using a corresponding define file module DF file and a user application module instruction.

Description

technical field [0001] The invention relates to a display and control method of target symbols of a cockpit display and control system, in particular to a display and control method of complex target symbols of a cockpit display and control system based on ARINC661 specification, belonging to the design field of integrated avionics systems. Background technique [0002] In order to adapt to the rapid development of the integrated avionics system, the Aeronautical Radio Association of America proposed the ARINC661 specification in 2001 to realize the decoupling between CDS (Display System, CDS) and UAs (User Application, UA), and provide standardization. The interface reduces the state changes of other equipment in the avionics system caused by frequent changes and upgrades of human-machine interface equipment, thereby achieving the purpose of reducing aircraft development and maintenance costs. [0003] Due to the particularity of its functions, the cockpit display and contr...
