网格化无线电监测网监测站点布局规划探索

Exploratory Research on Node Layout Planning of Grid Radio Monitoring Network

网格化无线电监测网是以原有无线电监测网为基础,通过在特定区域布放大量监测传感器节点建设而成,有效提高了无线电监测覆盖率和精细化监测程度,使无线电管理更加科学化、智能化。针对目前国内大中型城市无线电监测普遍面临的问题,选取无线电波传播模型仿真无线信号覆盖范围。仿真结果表明,无线电信号有效覆盖范围与传播环境、信号频率密切相关。根据仿真结果确定网格大小,并以昆明市电磁环境较为复杂的翠湖周边区域作为网格规划的试点目标区域,根据该区域的地理位置、地形地貌、人口密度和区域重要性等因素,探索完成了该区域内无线电网格化监测网监测站点布局规划。

Based on the original radio monitoring network,grid radio monitoring network is formed by setting a large number of monitoring sensor nodes in a specific area.It enhances the coverage ratio and accuracy of radio monitoring effectively and makes radio management more scientific and intelligent.To solve the general problems of radio monitoring in large/ medium cities of China at pres-ent,a radio wave propagation model is used to simulate the coverage radius of radio waves.The simulation result indicates that the effec-tive coverage radius of radio signals is closely related to the propagation environment and the signal frequency.According to the simula-tion result,the scale of the grid is determined.Finally,selecting the area surrounding Cuihu Lake as a planning pilot area,in which the electromagnetic environment is very complex,the monitoring nodes layout is accomplished according to the geographical location,topog-raphy,regional importance,population density and other factors of the area selected.
