[Abstract]:With the rapid development of modern avionics technology, the requirement of avionics system for data transmission is increasing. The airborne fiber channel fiber channel FCCnetwork is characterized by its high reliability, low cost, high speed and high real-time performance. Good expansibility and other advantages become the mainstream choice of airborne avionics network design in the future. FC network data simulation system based on embedded real-time operating system VX Works is a ground integrated simulation module designed to meet the future avionics system application. It combines the high bandwidth of optical fiber channel and high anti-interference ability. The advantages of low bit error rate (BER) and high real-time, reliability and good portability of VxWorks can simulate the process of data communication between nodes in airborne network by generating various kinds of data services satisfying FC protocol. The simulation system can connect to FC network and get a series of important data for reference by simulating the real-time operation of airborne network, which provides reliable technical support for the construction of airborne network. In this paper, the development status and characteristics of fiber channel technology and embedded real-time operating system are described, and the research direction of this paper is presented, which is FC network simulation system based on embedded real-time operating system VX Works. Then the basic principle of FC protocol and VxWorks embedded operating system is summarized. Then, the hardware architecture and the partition of software function modules of the simulation system are described in detail around the whole frame of FC network simulation system. The design of message sending and receiving of simulation system, the design of communication network (including the network design of test program) are analyzed in detail. For the two message frame structures of ASM frame and ELS frame, the frame composition and frame breaking are analyzed. The key technical problems involved in queue design and receiving and transmitting are studied. The overall test experiment of the whole FC network simulation system is completed, and the experimental method is improved, and a new test communication protocol is proposed. A new test software is developed to test the receiving and sending of messages. By analyzing the test data, the performance of the whole FC simulation system is preliminarily evaluated, and the shortcomings and improvement directions of the system are proposed. Finally, on this basis, the transplantation of FC network simulation system in different platforms is compared, the abstract interface is unified, and the feasibility of the design is verified.
