摘要
无线传感器网络是一种特殊的Ad-Hoc网络,网络中节点密集,数量巨大且分布在十分广泛的区域。目前,发展前景最为看好的是基于IEEE802.15.4标准的ZigBee无线网络。本文主要介绍基于Z igbee技术的定位系统的设计,结合射频芯片CC2420和单片机芯片PIC18F4620配合实现组成低功耗电路功能模块,并简单介绍了定位的方法。该系统可用于小范围战术环境下的人员定位,适合前线基层连队指挥官对战士方位及战场环境的把握,扩大了指挥与作战半径,增强了部队的战斗力。
Zigbee low power wireless networks, as the fittest plane for WSN in existing, are paid attention to increasing by people. This pa- per introduced the design of a personnel positioning system based on Zigbee. We use a radio chip CC2420 and a singlechip microcontroller PIC18F4620 to make a low power circuit module, and briefly intro- duced the positioning method. The system can be used for small- scale tactical environment of the soldiers position, and for com- manders to know the battlefield environment and the soldiers＂ posi- tion. It also expanded the radius of command and combat,and it enhance the combat effectiveness of the units.
