摘　　要：针对典型WSN网络中路由计算复杂、节点管理困难的问题,提出了终端节点、汇聚节点和监控中心三层次的硬件结构。用带有GPRS/GSM模块的汇聚节点充当WSN终端节点和监控中心的联络节点,并将终端节点分为1类、2类节点,用直接或多跳方式同汇聚节点联络,并给出了详细的处理流程。工程应用结果表明,这种硬件和软件设计可以节省大量软件算法,增强了对终端节点的实时监控及报警处理能力,扩展了典型WSN的功能和应用范围。In connection with the problem of the complexity of the route calculations and the difficulty of the node administration in the typical WSN,the hardware configuration consists of the terminal node,the convergent node and the monitor center is brought.The convergent node with the GPRS/GSM template served for the communication node between the terminal node and the monitor center,meanwhile,the terminal node is divided into first category node and second category node.It contacted with the convergent node by direct and multiple hop transmission,incidentally,the detailed processing flow is provided.The application engineering shows that the hardware-software design will save a lot of software algorithm,strengthen the real-time monitor and alarm handling ability to the terminal node,and extend the function and application spectrum of traditional WSN.
