钢丝绳状态无线监控系统节能方案研究与设计

Study and design of energy saving scheme of wireless condition monitoring system for steel wire rope

为了减少钢丝绳无线监测系统的能量消耗,延长整个无线传感器网络的生命周期,提出了一种新的节能设计方案。利用TPSN时钟同步算法,实现网络内节点的时钟同步,然后使空闲节点进入低功耗模式。利用RSSI测定终端节点运行的距离,当其距离父节点较远时,为保证通信质量,使其与离它最近的路由节点建立连接,继续执行数据的采集及发送过程。设计的监测系统有效地控制了能量的消耗,为整个网络的持续稳定运行创造了条件。

In order to reduce the energy consumption of wireless steel wire rope monitoring system, to extend the lifecycle of the entire wireless sensor networks, a new energy-saving scheme is proposed. Timing-sync protocol for sensor networks （TP-SN） clock synchronization algorithm is adopted for realizing clock synchronization of the nodes in the network, and then the idle nodes are set to low-power mode. RSSI is used to measure running distance of the terminal node. When the terminal node is far away from its father node, it is connected with nearest routing node in order to guarantee the communication quality, and contin- ues to collect and transmit data. The proposed monitoring system controls the energy consumption effectively, and create the con-ditions for the continuous and stable operation of the entire network.
