摘    要:为了实现对频谱资源的科学、有效管理,提高频率利用率,设计并实现了基于Android平台的智能频谱感知可视化系统。采用MVC软件模式进行系统框架设计,以实现整体系统结构的高内聚、低耦合。系统架构设计包含监测设备端、服务器端、客户端、百度地图4部分,服务器端对采集到的频谱数据进行FFT(快速傅里叶变换),并保存在MySQL数据库中,以方便用户对历史频谱数据的查询与分析。服务端与客户端采用安全性较高的C/S模式进行数据交互,以保障频谱信息的安全性。客户端采用成熟的SurfaceView和Opengl ES技术绘制二维、三维频谱图,以丰富应用程序的可视化功能,提升用户体验。实际应用结果表明,系统运行效果良好,对监测区域的频谱使用情况能进行直观的可视化呈现,可有效帮助监管部门了解监测范围内的频谱占用情况。

关 键 词:可视化管理  智能频谱感知  数据库  百度地图

Abstract:In order to realize scientific and effective visual management of spectrum resources and improve frequency utilization, an intelligent spectrum sensing visualization system based on Android platform is designed and implemented. The system framework is designed by MVC software mode to achieve high cohesion and low coupling of the overall system structure. The system architecture design includes four parts: monitoring equipment, server, client and baidu map. The server will carry out FFT (fast Fourier transform) on the spectrum data collected, and keep it in MySQL to facilitate the user to query and analyze the historical spectrum data. The server and the client use the highly secure C/S mode for data interaction, which ensures the security of spectrum information. The client uses the mature SurfaceView and Opengl ES technology to draw 2D and 3D spectrograms, enriching the visualization function of the application and increasing the user experience. Results of the real application show that the system has good effects.
Keywords:visual management  intelligent spectrum sensing  database  baidu map
