    摘要:

    針對航天器壽命延長(cháng)與功能復雜度提升帶來(lái)的對軟件在軌重構和升級的迫切需求,基于SpaceWire設計了一種對星載軟件升級與重構進(jìn)行統一管理的網(wǎng)絡(luò ),并設計實(shí)現了一款通用的軟件維護控制器;星載軟件重構網(wǎng)絡(luò )通過(guò)SpaceWire路由器連接大容量存儲模塊以及星載計算機、載荷處理器等需要進(jìn)行軟件重構的終端設備,大容量存儲器作為共享的存儲資源池,用于接收各類(lèi)星載設備的重構和升級軟件程序,直接將軟件程序通過(guò)SpaceWire分發(fā)到相應的設備,軟件維護控制器位于終端設備內部,對軟件重構數據進(jìn)行統一格式封裝,支持軟件升級數據的片段化更新、軟件ECC編碼存儲、軟件APP切換控制等功能,解決星載軟件升級缺乏統一操作流程、缺乏通用通信協(xié)議、缺乏高可靠設計支持的困境,并且該控制器采用抗輻射加固ASIC設計,滿(mǎn)足宇航使用環(huán)境要求,為實(shí)現星載軟件的靈活、便捷在軌重構奠定基礎。

    Abstract:

    In response to the urgent demand for software reconfiguration and upgrade in orbit brought about by the extended spacecraft life and increased functional complexity, a network for unified management of on-board software upgrade and reconfiguration is designed based on SpaceWire, and a universal software maintenance controller is designed and implemented; the on-board software reconfiguration network connects mass storage modules and on-board computers, payload processors and other end devices that need software reconfiguration through SpaceWire routers. The mass storage is used as a shared pool of storage resources to receive reconfiguration and upgrade software programs from various types of on-board devices and can directly distribute the software programs to the corresponding devices via SpaceWire. The software maintenance controller is located inside the terminal device, which encapsulates the software reconfiguration data in a unified format, supports the fragmentation update of software upgrade data, software error correcting code (ECC) storage, software application (APP) switching control and other functions, solves the dilemma of lacking unified operation process, lacking common communication protocol and lacking high reliable design support for on-board software upgrade, and the controller is designed with radiation-hardened Application Specific Integrated Circuit (ASIC). It meets the requirements of the space environment and lays the foundation for the flexible and convenient on-orbit reconfiguration of the on-board software.
