Virtualized radio tuning and audio management system for integrated avionics system

Abstract

The invention discloses a virtualized radio tuning and audio management system for an integrated avionics system. The volume of the system can be reduced, the onboard load can be reduced, the space can be saved, and convenient upgrade and update can be achieved on the premise of keeping the reliability. The system comprises two very high frequency radio stations, an audio control unit, a data processor, a navigation device, and two sets of audio control boxes and two sets of integrated display control units, which are respectively arranged in a front cabin and a back cabin, wherein the integrated display control unit is provided with a radio tuning and audio management graphical interface used for receiving an instruction input by an aviator and sending a control signal to the audio control unit, and sending an audio control source selection signal to the audio control unit through a discrete magnitude interface; and the audio control unit is used for performing the radio tuning and audio management of built-in call, external communication, emergency communication, navigation sound listening and alarm sound monitoring according to the control signal.

Description

technical field [0001] The invention relates to the field of aircraft airborne radio technology, in particular to a virtualized radio tuning and audio management system for an integrated avionics system. 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] With the development of avionics technology, the functions required by the airborne radio system are becoming more and more complex. The integrated radio system used on the aircraft undertakes various functions such as internal com...

AI Technical Summary

Problems solved by technology

Due to the need to concentrate the audio and control lines, in addition to setting up independent audio control boxes in each cabin, it is also necessary to reserve space for emergency spare audio control boxes in each cabin, so the radio tuning in the existing avionics system and The audio management system is complicated in structure and scattered, resulting in large volume and weight, which cannot be applied to small aircraft that have higher and higher requirements for flexibility, total fuselage weight and reliability

Moreover, when the integrated avionics system is upgraded and expanded, the centralized audio control box is limited by the hardware structure and centralized connection, and cannot be upgraded and updated accordingly, resulting in high costs for centralized control and hardware replacement
