摘要
车地通信检测装置用于检测车地通信FSK(频移键控)信号,可对FSK信号进行调制、发送、接收、解调等操作。介绍了检测装置的硬件和软件组成。检测装置的现场测试证实,它具有实时、可靠、防电磁干扰等功能,可对接收到的波形、解调数据、误码率等信息,进行实时存储、分析和显示,为车地通信系统的维护提供实用的资料。
This detecting device is used to detect the modulation, sending, receiving and demodulation of FSK signal, it consists of hardware （data acquisition card PXI6251 and related equipment） and software （LabVIEW8.5）, possesses real-time, reliable, anti-electromagnetic interference and other functions,it could also store, analyze and display the received waveform, demodulate data, the bit error rate and other information, providing practical information to the maintenance of train-ground communication system.
