摘　　要：本文围绕多山地区的无线广播电视信号覆盖特点,设计了一套信号覆盖效果评估系统。针对多山地区复杂的地形地貌对信号传播的影响,本系统创新性地采用了基于场强分贝点选择监测点的方法,与传统平原地区按距离均匀分布监测点的方式形成鲜明对比。此外,系统还融入了数据挖掘、人工智能等先进技术手段,能够更准确地分析信号强度变化规律及受众接收状况,从而有效识别出覆盖盲点和弱区。This article focuses on the characteristics of wireless broadcasting and television signal coverage in mountainous areas,and designs a signal coverage evaluation system.In response to the impact of complex terrain and landforms on signal propagation in mountainous areas,this system innovatively adopts a method of selecting monitoring points based on field strength decibel points,which is in sharp contrast to the traditional method of evenly distributing monitoring points by distance in plain areas.In addition,the system also incorporates advanced technologies such as data mining and artificial intelligence,which can more accurately analyze the changes in signal strength and audience reception status,thereby effectively identifying blind spots and weak areas of coverage.
