论述了导航设备集中监控系统中导航设备运行参数的采集与传输，重点分析了模拟信号和数 字信号的采集，并提出了利用调制解调器作为通讯接口的数据传输方案．该系统已经在民航东北空 管局导航站试运行，达到了导航台站无人职守的目的．
The collection and transmission of operating parameters of navigation equipment in the centralized monitoring system of navigation equipment are discussed. The acquisition of analog signals and digital signals are analyzed emphatically, and the data transmission scheme using modem as the communication interface is proposed. The system has been piloted at the navigation station of CAAC Northeast Air Traffic Control and reached the goal of unmanned navigation station.
