摘要
本文提出了基于虚拟仪器技术和自动化测试技术相结合的导航计算机检测设备。设备的上位机运行LabVIEW程序产生载体姿态信号,将信号通过RS232传输,最后在基于FPGA的硬件电路上产生与真实陀螺相同的输出信号。被测导航计算机在此输入信号下工作并给出导航计算的输出结果。数据采集由上位机完成,并以此评判导航计算机的状态,完成现场快速测试和故障诊断。本文主要论述上位机的工作,对FPGA的应用也作了简单介绍。
A navigation computer testing equipment based on the virtual instrumentation and automation testing technology was present in this article. LabVIEW programs was selected to make posture signal and transmit it to RS232. As the output, the signal of gyroscope attitude was generated on FPGA. Tested navigation computer works in this input signal and gives the output. Acquiring data,judging the status of navigation computer, making the quick test and fault diagnose by PC. The application of PC and FPGA were simply introduced in this paper.
