摘要:

ARINC659背板总线是综合化模块化航空电子系统的关键技术,逐渐用于国内军用民用飞机；在介绍ARINC659总线电气特性和分析电气设计要求的基础上,进行了设计应用实践,并对ARINC659总线在使用中出现的信号品质问题进行分析和仿真,得出信号回路上的寄生电容和寄生电感是导致信号输出端波形出现剧烈振荡和总线回环测试出错的根本原因,通过更改设计,减少ARINC659总线信号通道长度降低了信号寄生电容和寄生电感,使信号品质得到了极大的改善,满足了ARINC659总线电气设计要求,顺利通过了试验验证。

Abstract:

ARINC659 backplane bus is a key component of the integrated modular avionics system,It is gradually applied for Avion and Civil Aircraft. This paper introduces the electrical performance characteristics, analyzes the requirement of design and processes the application practice, In the use, Some problem about signal quality appears, By means of measuring and analyzing the signal wave, emulating the model, gaining that Parasitic capacitance and Parasitic inductance are the main factors influencing the signal quantity and testing pathologically, By the way of improving the design, cutting down the length of ARINC659 bus signal , Parasitic capacitance and Parasitic inductance are reducing properly , the improved design advances the signal quantity highly, meet the requirement of electrical design of ARINC659 bus and passes the experimentation.
