摘要
针对目前1553B总线测试设备仅能完成数据链路层性能测试分析,无法测试总线的物理电气特性,如波形电压、码元失真,无法测试总线"偶发"故障,测试消息不全、存在"漏消息"现象等缺点,提出了基于物理采样数据和软件译码的1553B总线数据获取方法,设计了1553B总线物理层测试模型,并利用1553B总线节点完成了该总线的数据获取实验,得到总线传输波形电压和码元波形,分析了1553B总线测试结果,验证了该技术的可行性。
Aiming at shortcomings that current 1553B Bus test equipment can only complete the DLL test and cannot test Bus＇ physical electrical performance, such as Waveform Voltage, Code Distortion, cannot test ＂Happening Malfunction＂, Messages to test are not all kinds, and there are ＂Lose Message＂ Phenomenon existing and etc, it brings forward a data acquisition technology to 1553B Bus based on Physical Sampling Data and Software Decoding, designs Physical Test Model to 1553B, completes the data acquisition experiment to 1553B with its bus nodes, obtains Bus Waveform Voltage and Code Waveform, and validates the feasibility to this technology.
