The Design And Testing Application Of The FC Avionice Network Simulation System

In recent decades the airborne electronic system entered a rapid development stage.During the process of development,the comprehensive degree of information becomes increasingly higher,and the requirements of real-time communication capacity of information,transmission rate and reliability are also raised.As an avionics network communication protocol of new generation,it should have features such as high speed,scalability,high reliability,low latency and the necessity to adapt to the requirements of open systems.Fibre channel(Fiber Channel FC)has the advantages of high bandwidth,low latency,insensitivity of distance,flexible topology,supporting multiple upper layer protocol,etc.It is a computer communication protocol designed to adapt the high performance data transmission requirements,which is suitable to be used as the communication protocol of the New Generation Avionics network.As the development of airborne avionics system based on the FC protocol,it is necessary to carry out a large number of simulation experiments in order to save manpower,material resources and time.In this thesis,the fibre channel protocol(Fiber Channel FC)technology and its application in airborne avionics network is as the main object of study.Based on in-depth analysis of the theory and technology on the principle of design,the FC avionics network simulation system has been designed.Numerous tests have been carried out to test its function and the application in the network environment.Based on the FC simulation system,we have done a lot of practical test applications in the FC network.These tests also support the development and testing of FC simulation systems from the side.For FC technology testing,there is no uniform test at home and abroad norms.As a result of technical blockade,China's FC simulation products testing technology as a whole backward,a new generation of avionics network bus product development speed is seriously affected.After the development of FC simulation products can not be more perfect to its own functional performance and in the FC network network parameters to test,so the FC network simulation product testing technology research urgently.The development and test of FC avionics network simulation system is completed in this paper.The development includes the design of the hardware framework and software module of the FC avionics network.The content of the test includes the integration test of the FC avionics network simulation system and the network performance test based on the FC avionics network simulation system.FC avionics network simulation system test has the following content: FC IP core test,FC simulation system function module test,FC simulation system performance test and FC simulation system compatibility test.The performance test of the network is as follows: the test of the uniform excitation source,the test of the FC switch as the excitation source,the delay and jitter of the FC network,the test of the network packet loss rate and the error rate of the network.
