Design And Implement Of Automatic Ground Testing Software For Space Vehicle Electronic Devices

Spacecraft electronic equipment is a critical part of the spacecraft system, the design of its systems and equipment manufacture requires a lot of manpower as well as high material costs, the spacecraft electronic device cannot be maintained associated with the spacecraft after launch. By using ground test system is an important mean to ensure the system be fully and completely tested. The main research results of this thesis are classified into three categories:(1) Considering the special needs of spacecraft electronic devices, the thesis has designed an automated test script language specification and the appropriate interpreter module referring the format of C language, Python language, etc. Then it has designed and implemented the module;(2) A configurable and reusable automated ground test system software architecture based on LabView has been constructed by using MVC framework. It has realized the abstraction and modulation of each module. It reduced the complexity of the software realization, improved the reuse ration of the software modules and made the software maintenance easy by analyzing the different requirements of different spacecraft electronics system;(3) Through analyzing the needs of the ground testing system of spacecraft electronic devices. The thesis has abstract three classes that contains 13 modules, then defined the interfaces and functions of these modules and formed an applicable ground testing software modules.There exists shortcomings of ground testing software system of the conventional spacecraft electronic devices, such as low software modularity and low software reuse,the automatic ground testing software system of spacecraft electronic devices has been designed and implementation. The system could be employed to complete the automatic testing and monitoring task of space vehicle electronic devices in the aerospace spacecraft and be compatible with different types of requirements. The system was implemented to improve the level of automation, enhance the efficiencyof ground testing of space vehicle electronic devices, gradually eliminate manual tasks involved in testing and monitoring, reduce the burden of testers as well as shorten test period, then increase the reliability of the testing results.
