基于ZigBee的无线定位技术研究 随着现代通信技术和无线网络的快速发展，人们对定位与导航的需求日益增大，尤其在复杂的室内环境但是受定位时间、定位精度以及复杂室内环境等条件的限制，比较完善的封闭空间定位技术目前还无法很好地利用。本文的重点就在于设计并实现了一种低成本、实用的无线传感器定位系统。 本论文主要研究了基于ZigBee网络的室内无线定位技术，它包括硬件平台、节点通信程序和上位机监测软件三部分。本文详细介绍了三部分的实现。其中，硬件平台以集成了射频与51微控制器的CC2430芯片为核心，该平台包括射频模块、辅助电路、功能指示电路等 论文最后对定位系统进行了实际测试。测试表明:本系统达到了设计要求，是一个低成本、易实现的系统。 Z-STACK The Research Wireless localization Based on ZigBee Teacher：liu zhi (Changchun university of science and technology of electronic information engineering institute,060412225 wang meng) Abstract： With the rapid development of modern communication technology and wireless network,peoples demand for positioning and navigation is increasing. Especially in complex indoor environments, ut as the limitation of positioning time, positioning accuracy as well as the complexity of the indoor environment conditions, well-positioning technology is still unable to be used in an encloseure space. The combination of ZigBee technology and localization is one of the key researches. This paper, aiming at ZigBee network, investigates the indoor wireless location techniques and implements a real-time localization system. This paper achieves a localization system. three parts are included. They are hardware platform, communication program of nodes and PC monitor software. The achievement of every part is clear introduced in this paper. The core of hardware platform is CC2430 which is integrated by RF and 51 MCU, the localization nodes are designed and made. It includes RF module, auxiliary module and function indication circuits. In the end, practical test is implemented. This system is confirmed to be a good one, it is a low cost and easy achieved system.
