Abstract

The invention provides a simulation and demonstration system for design and validation of an AFDX (Avionics Full Duplex Switched Ethernet) network and a simulation and demonstration method thereof, which are used for guiding the design of the AFDX network. The simulation and demonstration system mainly comprises an integrated avionics network design module, a loaded avionics communication task module, a plausibility check and validation module, a simulation module, a loadable configuration file output module, a network demonstration system module, and the like and has the functions of designing the avionics interconnection structure, simulating communication tasks of the AFDX network and validating the designed network topology in the network demonstration system module. The simulation and demonstration method is used for designing the network topology, simulating the avionics communication tasks and demonstrating and validating the designed network to obtain related technical parameters and provide the reference for the design of the AFDX network. The invention provides a more reliable scheme for the design of the AFDX network, shortens the design time, saves the cost, and improves the design efficiency.

Description

technical field [0001] The invention belongs to the field of avionics system communication network design, and in particular relates to a simulation system and a demonstration platform for AFDX network design and verification, which are used to simulate network structure design, link path generation, and communication task configuration in an aviation full-duplex network , loadable configuration file generation, and demonstration of networked hardware systems. Background technique [0002] The avionics system has gone through four stages of development: discrete, combined, integrated and advanced integrated. In the first generation of discrete type, the pilot must separately obtain the information of each subsystem and control and operate it independently; the second generation of combined type is an avionics system marked by data bus and integrated display control, such as the 1553 bus; The third-generation integrated type is an avionics system marked by the "Jewel Pillar"...

AI Technical Summary

Problems solved by technology

The structure and functions of the AFDX network are relatively complex. For example, there are 16-20 switches on an A380 aircraft, and each switch is connected to about 20 node machines. If a real system is used to verify the design idea, a lot of money and manpower are needed, and the efficiency is low.
