Research On Application Technology Of Batch Micro-nano Satellite Ground Parallel Automatic Test

With the increasing demand for micro-nano satellites,the increasing complexity of tasks and the continuous shortening of the development cycle,the traditional customized satellite ground test system has been gradually inadequate and began to withdraw from the historical stage.Then it requires that the current micro-nano satellite ground integrated test system not only ensures the basic stability,reliability and safety of batch and parallel testing,but also has more versatility,ease of use and automation.Therefore,this paper will focus on the application technology of batch micro-nano satellite ground parallel automatic testing.The specific research contents are as follows:According to the demand,this paper puts forward an integrated,scalable,tailored and open systematic solution,and designs a distributed system architecture with standard data source and interface as the core,multi-satellite resource allocation service as the command,parallel interactive service and standardized network middleware service as the link,automatic test platform as the pillar and all kinds of test front-end equipment as the foundation.And this paper researches on the key technologies required by the core of the architecture.For the designed system architecture,the software architecture of the most important part is designed,and the whole software is divided and realized into five functional modules,including graphical TPS generation module,test scheduling execution module,automatic test module,remote control and telemetry module,and standardized network middleware module.Finally,for the test software designed and implemented in Chapter 3,functional and non-functional tests are carried out in the development process of specific models.The results show that the software designed and implemented in this paper has sufficient security,reliability,stability and robustness.At the same time,it also shows that the software can realize multi-satellite parallel automatic test,meet the actual functional requirements,and thus realize the simple verification of the standardized network middleware and other technologies proposed above.
