在现代的航空电子综合系统中,1553多路传输总线担负着完成信息传输的重任。事实上,1553总线的系统设计已成为航空电子系统的系统设计的重要组成部份。本文讨论了在实施多路系统的设计时必须持有的若干系统考虑和基本观点,并分析了在系统设计中对某些因素进行权衡的准则。本文对于系统设计中的主要任务,诸如系统拓扑结构的设计、系统控制方案的设计、数据传输的安排、接口硬件的功能划分、总线资源的使用分析、以及系统测试等方面的问题,均作了较为详细的分析或讨论,并根据作者在总线研制过程中的认识和体会,对一些容易混淆的观点进行了阐述和澄清。
In the modern avionics integrated system, 1553 multi-lane transmission bus is responsible for the completion of information transmission. In fact, the system design of the 1553 bus has become an important part of the system design of avionics systems. This article discusses some of the system considerations and basic ideas that must be held in designing multi-channel systems and analyzes the criteria for balancing certain factors in system design. In this paper, the main tasks of system design, such as the design of system topology, the design of system control scheme, the arrangement of data transmission, the functional division of interface hardware, the use of bus resources, and system testing, are all made A more detailed analysis or discussion, and according to the author in the bus development process of understanding and experience, some of the views easily confused were clarified and clarified.
