以为读者提供优质阅读环境,保障图书使用寿命的同时实现图书馆节能为目的,提出基于无线传感器网络的图书馆环境监测算法。利用优化后的虚拟力算法优化无线传感器网络节点布局,对节点实施初始化处理。初始化结束后依照ECCTP路由算法构建路由,基于所构建的路由,利用基于单位时间内采集数据量最大化的数据采集路径规划模型规划移动采集节点路径,根据所规划的路径采集图书馆环境数据,并对采集的数据实施滤波处理。滤波后的数据发送至汇聚节点,汇聚节点上的环境数据传输至网关内供使用。实验结果显示,该算法可提升传感器节点的覆盖率,数据采集误差低于1.0 mm,单传感器信息采集所消耗的能量约为1.73/10^(-5) J。

In order to provide readers with quality reading environment,ensure the service life of books and realize the library energy saving,this paper proposes a library environment monitoring algorithm based on wireless sensor network.The layout of wireless sensor network nodes is optimized by using the optimized virtual force algorithm and the nodes are initialized.After initialization,the route is constructed based on the ECCTP routing algorithm.Based on the constructed route,the path of the mobile acquisition node is planned by using the data acquisition path planning model based on maximizing the amount of collected data in unit time.The library environmental data are collected according to the planned path,and the collected data are filtered.The filtered data are sent to the sink node,and the environmental data on the sink node are transmitted to the gateway for use.Experimental results show that this algorithm can improve the coverage rate of sensor nodes,the data acquisition error is less than 1.0 mm,and the energy consumption of single sensor information acquisition is about 1.73/10^(-5) J.
