摘　　要：提出了一种采用集中式处理方式的ZigBee无线传感网络定位系统。该定位系统由网关节点、参考节点、子网关(增强型参考节点)、移动终端节点和PC服务器组成,可实现实时定位、终端报警等功能,具有实时性高、能耗低等优点。为了克服复杂环境和地域范围对ZigBee无线网络覆盖的制约,将整个无线网络分割成多个子网,并与传统的TCP/IP协议通信实现融合。该无线定位系统辅以相应传感器可同时用于数据采集和监控等应用。The design of a centralized wireless positioning system is proposed based on ZigBee technology. The positioning sys tem consists of a dongle node, reference nodes, subdongle nodes （enhancedreference nodes）, mobile terminal nodes and a PC server. The system provides multifunctions such as the realtime positioning and terminal alarming with advantages of instant response and low power consumption. To overcome the limitation of environment complication to the coverage of ZigBee wireless sensor network, the wireless network is divided into several subnets and combined with the traditional communication based on TCP/IP protocol. This wireless positioning system is applied to the data acquisition and monitoring with the aid of appropriate sensors.
