The invention discloses a bus-type power distribution architecture adaptive to an extensible micro-nano satellite platform, relates to the field of micro-nano satellites, and aims to solve the problems that an existing satellite power supply and distribution system is complex in architecture, each device is difficult to support more peripherals due to an independent power distribution cable, the expansibility is poor, and the cable topology is complex. The system comprises a 1-Wire bus, a bus power supply and a power distribution unit, a bus power supply is adopted to provide power for each single machine, local power-on and power-off control and telemetering parameter return of each single machine are realized through a 1-Wire bus, and the power distribution unit realizes power-on and power-off control of electric equipment; according to the high-reliability power distribution bus architecture based on the single bus, extremely simplified cable topology is adopted, power distribution control and feedback quantity collection of on-satellite equipment are achieved, double-bus cross backup is easy to achieve so as to ensure reliability, and the architecture has good expandability, can support hundreds of equipment and is high in reliability. And the method is very suitable for a micro-nano satellite platform with relatively high expansibility requirements.

    适应可扩展微纳卫星平台的总线式的配电架构,涉及微纳卫星领域,为解决现有卫星供配电系统架构复杂,以及由于每台设备由一条独立的配电线缆难以支持更多外设,扩展性较差且线缆拓扑复杂等问题,本发明包括1‑Wire总线、母线电源与配电单元;采用母线电源为各个单机提供电源,以1‑Wire总线实现各个单机的本地加断电控制及遥测参数回传,所述配电单元实现用电设备的加断电控制;本发明基于单总线的高可靠配电总线架构,采用极简化的线缆拓扑,实现星上设备的配电控制及反馈量采集,且易于实现双总线交叉备份以保证可靠性,该架构具有良好的可扩展性,可以支持上百台设备,非常适用于对扩展性要求较高的微纳卫星平台。
