摘要
针对卫星导航接收机现有测试设备测试仪器分散、连接复杂、自动化程度低、耗费高等问题。本文设计了一种基于虚拟仪器技术的卫星导航接收机自动测试系统,通过PXI总线的工控机及高效的接口适配器为硬件平台采集接收机板的输出信号。上位机软件采用LabVIEW,对采集到的数据进行处理、显示及结果保存。该系统具有易操作、测试精度高、便于扩展、通用性强等优点,极大地提高了复杂系统的测试效率。
Aiming at the problems of scattered test equipment,complex connection,low level automation and high cost of the existing test equipment for aviation satellite navigation receiver.This paper designs an automatic test system of satellite navigation receiver based on virtual instrument technology,through the industrial control computer of PXI bus and efficient interface adapter as the hardware platform to collect the output signal of receiver board.The test sofeware adopts LabVIEW,processing the collected data,saving and displaying the results.The automatic test system was easy to operate with high precision,upgrade and generalize,improving the test efficiency of the complex system vastly.
