摘 要:大型卫星通信地球站具有多频段、多系统工作特点,信号测量手续复杂,仪表频繁搬动和电缆反复插拔耗费人力,容易造成电缆及接头损耗。设计了多输入信号频谱监测设备,采用Visual C#可视化编程语言,通过TCP/IP协议编程,实现SCPI规范的频谱模块控制,使用Measurement Studio控件操作和显示频谱仪状态及数据,实现网络化频谱监测。使用基于MODBUS协议的TCP/IP数据转换板,结合射频切换开关,实现多个射频输入端口的远程网络化切换。该设备适用于大型卫星通信地球站,能远程完成信号监测任务。The large scale satellite earth stations have the features of mulitband signals,multi-systems and complex signal measurement methods.Frequent removal of equipment and cable pluging cause has labor cost,and it can easily lead to loss of cable and sockets.The networking device to monitor the multi-input signals' spectrum is designed.Through the TCP/IP protocol programming,Visual C# programming language is adopted to realize the control of spectrum module with SCPI specification.First,the programm gets data from the spectrum module,then it plots the signal on screen using the Measurement Studio controls,finally it monitors the signal spectrum via the TCP/IP network.Remote networking switch of multiple RF ports is realised based on the board from TCP/IP to ON/OFF logical stutas and MODBUS protocol.The device is suitable for the large scale satellite communication earth station,and can meet the demand of remote control and remote monitor of signal selected from many antennas.
关 键 词:MODBUS TCP/IP SCPI 射频切换 频谱监测
