摘　　要：首先介绍了无线传感器网络的基本拓扑结构与传感器节点的结构,详细说明了基于ZigBee协议栈的无线传感网络的建立过程,包括协调器启动及建立网络、传感器节点启动及加入网络、传感器节点与协调器之间建立绑定以及传感器节点向协调器发送数据的过程。设计了基于ZigBee协议栈的无线传感网络系统。以采集温度信息为例,协调器能够接收到传感器节点发来的数据,并能通过RS232串口,将收到的数据发送给PC机进行显示。实验显示在距离80 m远处,系统仍能保持良好的通信质量。First, the basic topological structures of wireless sensor network and the structure of sensor node are introduced. The starting-up process of wireless sensor network based on ZigBee stack is explained in details, including startup and establishing network of coordinator, startup and joining network of sensor node, binding between sensor nodes and coordinator, and the process of terminal nodes sending data to coordinator. The wireless sensor network is designed based on ZigBee stack. Taking sampling temperature information as a example, the coordinator can collect the information from sensor nodes, and send them to PC by using RS232. The temperature information can be displayed in PC. The experiment shows that good communication quality of this system can be obtained, although at the distance of 80 meters.
