摘要:自全式无线传感器采集周围环境中的能量并转化为电能,能够实现传感节点能量的自给自足。结合自全式无线传感节点的应用环境,分析不同路由协议对节点能耗的影响。摒弃了节点能耗大的动态组网方式,构建了适用于自全式无线传感器的静态网络模型。分析了无线传感网络中影响不同节点能耗的因素,针对网络中不同功能的节点,选用不同的工作方式。通过软件控制传感节点工作状态的切换,降低了传感节点的能耗。实验测试了网络中传感节点的能耗和网络的传输性能。并将其应用于电线监测中,完成了对电线温度、电流参数的监测任务,减少了网络节点维护成本,提高了网络的寿命。

Online Monitoring Network Using Self-contained Wireless Sensors
Abstract:Self-contained wireless sensors which harvest energy from ambient environment can achieve energy self-sufficiency. Combined with the applications of self-contained wireless sensors, we analyzed the impact of different routing protocols for sensing nodes energy consumption. Abandoned the higher energy consumption dynamic networking mode, the static network model is constructed to be appropriate for self-contained wireless sensors. We analyzed the factors affecting energy consumption of different nodes in wireless sensor network. According to the different function of nodes in the network, different ways of working were used. By switching the software to control the working status of sensing nodes that it reduced the energy consumption of sensing nodes. Test indicates the sensor nodes' energy consumption and the transmission performance of the network. Appling it to the electric wire monitoring, we achieved the task of the temperature of wire and current parameters, reducing network nodes' maintenance costs and improving the lifetime of the network.
Keywords: wireless sensor energy harvesting wireless sensor network electric wire monitoring
