Software Design Of FC-AE Simulation Node Card Controller

The FC-AE protocol cluster is an important application in the avionics environment of the optical fiber network.The protocol cluster includes FC-AE-ASM and FC-AE-1553 and many other upper layer protocols.The FC-AE-1553 is a command-response structure and it is the implementation of MIL-STD-1553 B on the FC-AE protocol cluster,and it combines the advantages of MIL-STD-1553 B and FC-AE-1553.It has been used as a communication protocol of U.S.military avionics network.In our country,it has gradually been used in many field such as the warship and aircraft.FC-AE-ASM is different from the FC-AE-1553-AE-1553 networking.It has a point to point anonymous transmission structure and it is simpler and faster.It has many applications in radar video and time triggered network.Both of them are hot topics in FC-AE protocol cluster research.FC-AE node card is one of the most critical components in FC-AE network,and there are many protocols under FC-AE.In order to implement node cards supporting multiple FC-AE protocols,this thesis is mainly designed a terminal display interface of multiple FC-AE node cards controller software.The software consists of host computer and slave computer two levels system and it control the remote FC-AE node cards through Ethernet.The system is designed for FC-AE-ASM and FC-AE-1553 simulation.Compared with the traditional node card,this structure saves more hardware resources,human resources and space resources,and it is more convenient for different node cards to simulate in different protocols under the condition of fewer people.So it has certain innovation and research value.Firstly,this thesis introduces the background and significance of this topic and point out that there is no precedent for FC-AE node card simulation under this structure,so it proves the feasibility and value of this project.Then this thesis makes a brief introduction to the several protocols,based on the basic understanding of protocol,the thesis put forward a preliminary design of the project and design the function module for the software.Then,the detailed design is carried out on the based of the outline design.It includes the driving part under different platforms and the realization process of each module of the upper software.The thesis will focus on the main functions of protocol simulation: data transceiver,and give a detailed description of how data are received and sent under two different modes of FC-AE-ASM and FC-AE-1553.Finally,according to the implemented functional modules,the functional tests and performance tests under the two protocols are given.The test result verify the feasibility of the two kinds of simulation for small scale and multi node card data interaction under the structure of the host and slave computers.In view of the research at the present stage,the thesis point out the shortcomings of the research and put forward the direction of the next research.
