Abstract:In order to improve the efficiency of integrated test of launch vehicle electrical system and meet the requirement of high-density, a virtualization integrated test platform is designed in this paper which based on secure private cloud technology. This platform has a general hardware and software architecture, which integrates the functions of graphical editing, automated testing, data processing, fault diagnosis and so on. It can realize multi-task parallel testing. Compared with the traditional test mode, the platform has obvious advantages on testing efficiency and effectiveness.
