Abstract: The electronic datasheet can solve the plug and play of spaceborne components of spacecraft. When it is used in the space data system, it needs a series of software tools to support the management and editing of electronic datasheets. At the same time, with the increase of tools, the demand for independent and scalable electronic datasheet toolchain architecture is gradually increasing. Based on the requirement of electronic datasheet toolchain, this paper designs an electronic datasheet toolchain management system based on plug-in layered architecture. This research defined the development method and interface specification of application plug-in, and proposed a technical implementation scheme of toolchain management system based on open service gateway initiative(OSGi) and Eclipse RCP. The results show that the electronic datasheet toolchain management system based on plug-in architecture can meet the actual function and application requirements, and meet the independence and scalability of tool organization.
