中小型无人飞行器二余度CAN总线网络设计

摘要

无人飞行器行业的竞争日趋激烈,性能与成本因素在竞争中占主导地位;介绍了一种基于二余度CAN总线的航电系统设计方法,并对二余度总线、通信接口、关键环节的冗余设计以及系统可靠性做了进一步地研究;采用二余度CAN总线的航电系统设计,可以在提高系统集成度和保证系统可靠性的前提下,既满足小型化设计的要求,又能够提高系统的综合性能.%As UAV industry is becoming more competitive, performance and cost of UAV domintate in the competition. The paper describe the design of avionics system based on dual -redundancy CAN bus, giving further research of dual-redundancy, bus communication interface, the redundancy and system reliability. Using the design of avionics system based on dual -redundancy CAN bus, system improve comprehensive performance as well as meet requirements of miniature design, with the premise of improving system integration and ensuring the system reliability.
