Network design method of airborne multi-topology double switching structure

Abstract

The invention discloses a network design method of an airborne multi-topology double switching structure, and belongs to the field of aircraft integrated control technology. The design method comprises a topological structure, a protocol level, redundancy configuration and management mechanism of an airborne system high speed transmission network, a hybrid topological structure formed by a point-to-point access network, a switching access network and an annular bus access network is used for realizing the communication and processing among sub-systems and modules of aircraft management, thereby ensuring the reliability and the stability of the airborne system network, satisfying the real-time requirements of the sensors, function units and subsystem functions of the aircrafts, and the transmission matching requirements of the high speed data processing system and a large amount of real-time data information, therefore the objective of information sharing and function integration is realized by information interconnection, the high speed transmission of large-capacity airborne data with high reliability is realized, the function limit of the original airborne system is broken, and the integration of the airborne system and the sharing of data, hardware and other resources are promoted.

Description

technical field [0001] The invention belongs to the technical field of aircraft comprehensive control, and in particular relates to a network design method of an airborne multi-topology double-switching structure. Background technique [0002] Each electronic device or subsystem on a modern aircraft (such as flight control, thrust control, radar, communication and navigation, control display, weapon external management, etc.) is equipped with an independent computer. In addition to real-time processing, information cross-linking is also required to achieve the purpose of functional integration. The aircraft management system came into being under this background. The aircraft management system takes the subsystems related to the flight capability and maneuverability of the aircraft as objects, combines a wider range of public subsystems through internal communication, and dynamically allocates resources to achieve more in-depth function integration and multi-mode integration...

AI Technical Summary

Problems solved by technology

At the same time, the integration of the aircraft management system has also brought some new problems. First, the airborne data needs to be integrated at the signal level, and the amount of airborne data that needs to be processed has increased sharply; Not only commands and data, but also a large amount of intermediate result data, which requires the bus to have Gb / s bandwidth and microsecond-level data delay
