基于虚拟仪器技术的电台自动测试系统

Automatic test system of broadcasting station based on virtual instrument technique

针对电台发射机功率频率的自动测试问题,利用虚拟仪器技术设计和开发的自动测试系统,使计算机通过UDP与频谱分析仪进行通讯,通过串口与电台进行通讯。在该系统中,结合设计的虚拟仪器软面板,通过远程命令可控制电台进行发射,设置频谱分析仪参数,进行数据采集,实现了对电台载波频率功率的自动测试。整个测试过程可完全由计算机控制,避免人工干预,从而实现了对被测设备的自动测试。

Design process of automatic test system of broadcasting station based on virtual instrument technique was introduced. Communication between computer and spectrum analyzer was realized by UDP using serial port to communicate with broadcasting station. With the soft panel designed in the automatic testing system, emitting of broadcasting station and data acquistion of spectrum analyzer are achieved by executing remote demands. Without manual intervention, testing of frequency and power are controlled by the computer and this realized automatic testing.
