【摘要】：光纤通道（Fibre Channel）是目前国内外首选的航电网络总线，我国也正在研发相关的FC-AE总线产品，用于新一代机载航电系统。然而，由于缺乏自主的测试方法和测试平台，所以依然要依赖国外的测试机构对FC协议总线产品进行测试，这严重影响了相关产品的研发进度，因此深入分析和研究航空电子环境下的光纤通道协议（FC-AE协议），得到具有自主知识产权的测试方法，已经刻不容缓。本文对光纤通道FC协议进行了深入地分析和研究，总结归纳了该协议的测试方法；使用基于FC协议接口芯片的FC仿真测试卡，设计并实现了支持点对点拓扑结构和交换网络拓扑结构的测试模块，搭建仿真测试平台，设计测试软件，，初步对部分功能测试和性能测试的方法进行了验证。文中对光纤通道FC协议的测试需求进行分析和归纳总结，从物理层光信号测试、物理层电信号测试、网络层功能测试和网络层性能测试这四个方面分析和研究测试需求和测试方法；在网络层的实现上利用模块化的设计思想，分别设计了硬件初始化、注册注销、数据分帧重组、流量控制块和差错处理等功能模块，并采用故障注入的方式，模拟了数据帧的SOF、帧头、负载、CRC、EOF等的错误，仿真了FC-AE总线通信过程中的瞬时故障、间歇故障和永久性故障，实现了对光纤通道协议一致性测试。
[Abstract]:Fiber Channel (Fibre Channel) is the preferred avionics network bus at home and abroad. Our country is also developing related FC-AE bus products for the new generation airborne avionics system. However, due to the lack of independent testing methods and test platforms, we still have to rely on foreign testing institutions to test FC protocol bus products, which seriously affects the progress of research and development of related products. Therefore, it is urgent to analyze and study the fiber channel protocol (FC-AE) in avionics environment and get the test method with independent intellectual property. In this paper, the fiber channel FC protocol is deeply analyzed and studied, and the testing methods of the protocol are summarized, and the FC simulation test card based on FC protocol interface chip is used. The test module supporting point-to-point topology and switching network topology is designed and implemented. The simulation test platform is built and the test software is designed. The methods of partial function testing and performance testing are preliminarily verified. In this paper, the testing requirements of fiber channel FC protocol are analyzed and summarized. The physical layer optical signal test, physical layer electrical signal test, physical layer electric signal test, Four aspects of network layer function test and network layer performance test are analyzed and studied, the test requirements and test methods are analyzed and studied, and the hardware initialization, registration cancellation and data frame recombination are designed in the realization of the network layer using the modular design idea. The flow control block and error handling module are used to simulate the errors of the data frame such as SOF, frame head, load CRC / EOF and so on, and the transient, intermittent and permanent faults in the communication process of FC-AE bus are simulated. The conformance test of fiber channel protocol is realized.
