基于FPGA的卫星地球站ODU监控系统设计

Design of satcom earth station ODU monitor system based on FPGA

为了能够对卫星地球站ODU进行控制与检测,设计了基于FPGA的卫星信号收发机监控系统。该监控系统能够完成ODU的全部控制功能,并且通过检测24个通道的模拟信号来监视ODU的工作状态,能够以两种通信方式与计算机或控制终端通信。设计中将FPGA依据功能划分为几个模块,并论述了各模块的设计方法与程序流程。通过仿真与实验,表明该监控系统工作可靠,能够满足需要。

A monitor system based on FPGA was designed for controlling and detecting the satellite communication transceiver.This monitor can handle all the control requests of ODU,monitor the working status of ODU by detecting the 24-channel analog signals,and communicates with the computer or control terminal through two kinds of mode.The FPGA is divided into several modules according to functions,and the design method of each module and their processes and procedures were discussed in detail.The simulation and debugging test suggest that the whole system is able to meet the requirement for practical applications.
