摘　　要：由于输电线路通常比较长,因此在部署无线传感网络基站时受信号覆盖范围的影响较大,降低巡检效果。为此,面向输电线路巡检提出一种无线传感网络基站最少化部署方法。为了保证最大化输电线路巡检覆盖范围,分析无线传感网络基站部署中的最大覆盖率和吞吐量影响因素。以此分析结果为基础,将最少基站数量作为部署优化目标,对无线传感网络中的基站展开部署优化。仿真结果表明,所提方法基站数量最多为12个,部署基站所需的时间低于9.3 s,最小生命周期为1117轮,覆盖率在95%以上。由此可知,所提方法部署的基站满足最少化原则,且部署效率高,基站部署均匀性好,监测覆盖率高。Due to the usually long transmission lines,the deployment of wireless sensor network base stations is greatly affected by the signal coverage range,which reduces the inspection effect.Therefore,a method for minimizing the deployment of wireless sensor network base stations for transmission line inspection is proposed.To ensure maximum transmission line inspection coverage,the factors affecting maximum coverage and throughput in the deployment of wireless sensor network base stations are analyzed.Based on this analysis re-sult,the minimum number of base stations is taken as the deployment optimization objective to optimize the deployment of base stations in wireless sensor networks.The simulation results show that the proposed method has a maximum number of 12 base stations,a deploy-ment time of less than 9.3 seconds,a minimum lifecycle of 1117 rounds,and a coverage rate of over 95%,demonstating the proposed method deploys base stations following the principle of minimization,and have high deployment efficiency,good uniformity of base station deployment,and high monitoring coverage.
