摘要: 脉冲编码调制(PCM)技术因为其良好的抗干扰性能,被广泛应用于飞行器的地面测试与飞行试验当中。为了监控被测飞行器的运行状态,通常需要对测试过程中的PCM数据进行实时接收显示。提出了一种基于LabVIEW的PCM数据实时接收系统的设计方法,通过采用数据接收卡与上位机程序相结合的方式,实现了对PCM数据的实时接收显示。经验证,该系统可满足飞行器地面测试的需要。

Abstract: Pulse code modulation (PCM) technique has high ability of anti-jamming and has been widely used in ground test and flight test of spacecraft. To monitor the running state of the spacecraft, it is necessary to receive and display PCM data in real-time in the test process. A design method of PCM data real-time receiving system based on LabVIEW is presented. The real-time receiving and displaying of PCM data are realized by combining the data receiving card with the host computer program. The verification shows that the system can meet the requirement of spacecraft ground test.
