摘要
有线大坝安全监测系统的线缆敷设是一项复杂的工程,且其监测点的安装、调整、扩充等也不方便。文中提出一种基于ZigBee无线传感器网络的大坝安全监测系统。无线网络由一系列监测节点、路由节点以及终端协调器组成,各监测节点依靠路由节点转发其监测数据至终端协调器,通过通用分组无线电业务(GPRS)网络传送到监控中心。给出了无线传感器节点、协调器的设计,根据水库大坝监测系统的网络拓扑结构,设计了一种有效的分级路由策略。
The cable laying of a dam safety monitoring system is a complicated project, and the installation, adjustment and expansion of the monitoring points are also discommodious. A ZigBee-based wireless sensor network for the dam safety monitoring system is proposed, which is made up of some monitoring nodes, router nodes and terminal coordinator. These monitoring nodes transfer data to the terminal coordinator through the router nodes, and to the monitoring center through GPRS. The design of the wireless sensor node and coordinator is introduced, and an effective graded router strategy for the dam safety monitoring system is designed.
