摘要
由于具备较强的鲁棒性、确定性及抗干扰能力,1553B总线被广泛应用于航空、航天、兵器等军工领域,但其1 Mb/s的总线带宽限制了其应用范围,高速1553B总线在保持原有通信协议、线缆、耦合器等基础技术或设备不变的条件下,仅通过更换1553B模块即可实现带宽的成倍增长,提高了1553B总线的应用范围及生命力。搭建高速1553B总线有效性测试平台,该平台能够实现误码率、噪声抑制、通信协议等内容的自动化测试,并形成测试报告,通过该平台验证了国产化高速1553B模块完全符合设计要求,为高速1553B总线的工程化应用提供了保证。
The 1553B bus is widely used in aviation,spaceflight,weapons and other military areas due to its strong robust?ness,anti?jamming capability and good determinacy,but its application range is limited by the bus bandwidth of 1 Mb/s. Under the condition that the original communication protocol,cable,coupler,and other infrastructure technologies or equipments are maintained the same,the bandwidth of the high?speed 1553B bus is enlarged manyfold by only changing the 1553B module to expand its application range and strengthen its vitality. The validity test platform of the high?speed 1553B bus was established.The platform can realize the automatic test of the bit error rate,noise suppression,communication protocols,etc.,and generate the test reports. The issue that the high?speed 1553B module is completely in conformity with the design requirement was verified with the platform,and provides a guarantee for the engineering application of the high-speed 1553B bus.
