摘　　要：针对平流层无人飞艇能源系统的CAN总线通讯架构,对常用的几种传统CAN总线连接拓扑进行可靠性分析、对比,得出这几种拓扑连接网络的优劣势,结合当前发展,提出一种双裕度CAN总线可靠性模型,并在此模型基础上,对平流层CAN总线单线式和级连式两种电缆拓扑结构进行对比分析,对于设计平流层无人飞艇能源系统CAN总线通讯架构形式具有重要的指导意义。Aiming at the CAN bus communication architecture of the energy system for stratospheric unmanned airship,the reliability analysis and comparison of several commonly used traditional CAN bus connection topologies were carried out,and the advantages and disadvantages of the topological connection networks were obtained.The double-margin CAN bus reliability model were proposed,and on the basis of this model,the comparative analysis of the two cable topologies including single wire and cascading of the stratospheric CAN bus was carried out.The research has important guiding significance for designing the CAN bus communication architecture of the energy system for stratospheric unmanned airship.
