The Design And Implementation Of The Automatic Test Preparation System Of The Spacecraft Low Frequency Cable

The low frequency cable network of spacecraft is an important device between eachsubsystem equipments or ground equipments. It can realize some function such as electricitytransmission, instruction transmission, and information exchange and so on. So it likes the“blood vessels” and “neural network” in the system of satellite and spacecraft. Thus thequality of the network is critical to the craft’s comprehensive performance, and determines thesuccess of failure of the mission. Especially for the manned missions, it has a greatrelationship with the life of astronauts. So it is more significant to test well.Nowadays, the technology applied in the automatic test of spacecraft cable is more andmore mature. Some native institutes of CASIC have already imported foreign advancedtesting system, but the system is not apply to the craft cable in China for its specialcharacteristics. Therefore, we must develop a "test preparation system", which can fulfill thepreparations before the test and make the universal test equipment can be used in the realengineering application.The main functions of the system: test solution preparation, test datapreparation, the automatic generation of test program, guiding the access control and plug ofthe transfer tool, etc.In this paper introduced the overall design, detailed design and the relevant technologyof the system, and the realization of the function modules of the hardware and software. Thenelaborated the system application examples, analyses the test results.Finally, it summarizedthe content of the thesis, and put forward some suggestions and improvement.
