基于DAQ和FPGA开发星务软件测试平台

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。

Development of Satellite Service Software Test Platform Based on DAQ and FPGA Module

Design of a satellite service software test platform based on DAQ(Data AcQuisition) and FPGA(Field-Programmable Gate Array) is presented to meet higher and higher requirements of aerospace software for automatic and universal tests.DAQ and FPGA cards of NI(National Instruments) are used in the PXI(PCI eXtensions for Instrumentation) system to facilitate data exchange with satellite software and LabVIEW is used to faclilitate signal analysis and user-friendly interface.It performs well automated dynamic tests and fault simulation tests for series of satellite service software and significantly shortens test cycle and increases test efficiency.Therefore,the platform well meets requirements of modernized tests on aerospace software.
