| 摘 要： | 针对无线射频传输距离有限的缺点,提出一种利用GPRS网络和分簇结构的WSN实现远距离数据传输的管道腐蚀远程监测系统设计方案.设计了多功能的低功耗WSN节点,并提出适用于管道腐蚀实时监测的链式路由、簇内基于TDMA的MAC协议和以RTC为基准的时间同步机制.测试结果表明节点采集数据误差在4mV以内,簇头和传感节点最大工作电流分别为300mA和170mA,休眠时电流都小于65uA,满足实际监测需求,在远程监测应用中取得了良好的效果.

| Abstract: | For the limitation of distance of RF transmission,this paper proposes a design of PCRMS(Pipeline Corrosion Remote Monitoring System) which implements long-distance wireless communication between WSN nodes and control room by combining GPRS network with cluster-based wireless sensor network.The multifunctional and low-power WSN nodes are designed,and the system adopts chain routing,the MAC protocol which based on TDMA in clusters and RTC-based time synchronization which are adapted to PCRMS.Test results show... |
