分布式电磁频谱自动监测系统研制

为实现对多个区域的电磁环境同时进行监测,分析了分布式电磁监测系统的设计原则,确立了监测系统的硬件连接方案,利用以太网-GPIB控制器、集线器和控制计算机来对多台仪器进行集中控制的方式,设计了相应的系统软件。测试结果表明,该系统具备同时控制多台频谱分析仪的功能,能够实时测量电磁频谱、背景噪声、频段占用度等数据,具备测量数据存储、回放与分析、报表生成的功能,具有状态反馈和异常状态提示的功能,完全能满足多个区域电磁监测的要求。

Development of distributed automatic monitoring system for electromagnetism spectrum

In order to monitor the electromagnetism environment of many regions simultaneously, the design principle of distributed EM monitoring system is analyzed, the hardware connection scheme of the monitoring system is established, and the way of using a LAN to GPIB controller, a HUB and a computer to control many instruments is adopted, and the soft is developed. The test results show that the system has the function of controlling multiple spectrum analyzers, can measure the parameters of electromagnetism spectrum, background noise, frequency band occupancy, have the function of saving, play backing and analyzing the measurement data, and have the function of state feedback and abnormal state prompting, so the system can meet the requirements of electromagnetic monitoring in many areas.
