Based on the integrated electronic system level model, a design scheme of a distributed spacecraft integrated electronic system is proposed and implemented. The program uses standard common hardware modules, ASIC chips, hierarchical bus architecture and space communication protocol as the basic technical support, using distributed collaborative and parallel processing, both to enhance the information network service capabilities and information processing power, but also Hardware modules and resources can be shared and task migration and system reconfiguration. The application on spacecraft shows that this scheme can effectively improve the operation efficiency and task processing ability of the integrated electronic system, enhance the tolerance and handling ability of the integrated electronic system to the fault, and can also significantly improve the development efficiency and product level of the integrated electronic system , So that the integrated electronic system to provide high reliability, intelligent spacecraft to provide the necessary technical support.
