针对航天软件自动化测试和测试通用性要求的不断提高,提出基于DAQ(数据采集)和FPGA(现场可编程门阵列)的星务软件测试平台构建方案,在PXI(PCI eXtensions for Instrumentation,外设部件互联标准在仪器领域的扩展)系统环境下应用NI(美国国家仪器公司)的DAQ板卡和FPGA板卡实现星务软件外围数据的仿真模拟,应用Lab-VIEW编程实现信号的解析和良好的人机交互界面。在实际测试中,它能够很好地完成一系列星务软件的自动化动态测试、故障模拟测试等,大大缩短了测试周期,提高了测试效率。此平台完全满足航天软件现代化测试的要求,具有开发周期短、使用效率高、通用性强等优点。
In order to improve the automation requirements of testing and testing of aerospace software, this paper proposes a scheme of constructing the test software platform of satellite service based on DAQ (Data Acquisition) and FPGA (Field Programmable Gate Array). In PXI (PCI eXtensions for Instrumentation, Interconnect standards in the field of instrument expansion) System environment application NI (National Instruments Corporation) DAQ board and FPGA board to achieve satellite software peripheral data simulation, the application of Lab-VIEW programming signal analysis and good people Machine interface. In the actual test, it can accomplish a series of automated dynamic testing and fault simulation test of Starburst software, which greatly shortens the test cycle and improves the test efficiency. This platform fully meets the requirements of modern testing of aerospace software, has the advantages of short development cycle, high efficiency and versatility.
