文档介绍：基于Zigbee的监区人员定位研究
摘要随着监狱关押犯人的数量不断增加,犯罪人员社会成分复杂,许多犯罪人员还是技
术犯罪,思维活跃,加之监狱的监管不利,导致个别发生袭警越狱事件,对社会造成极其恶劣的影响。犯罪分子越狱会选择深夜以及大雨大雾这样的恶劣天气,传统的依靠人工预防加摄像头监控的管理方式,已经无法满足现代监狱管理的要求。
为了方便有效的防止犯罪分子的逃脱,提出了基于 Zigbee 技术定位网络的搭建。首先给出了监区囚犯定位系统总体设计和系统的工作原理。其次,对两种典型的路由协议 AODV 和 DSR 进行仿真和分析,并通过 NS2 网络模拟器对它们的分组投递率和归一化路由开销性能进行了仿真和比较,最终我们选用 AODV 路由协议。最后,搭建了四个参考节点定位一个中心节点的 Zigbee 无线定位网络,并通过网关节点把接收到的数据传到上位机,2430 芯片,2431 芯片。
通过模拟定位效果测试,结果表示,中心节点可在 64m×64m 范围内四个参考节点内实现定位,平均定位误差为 米,进一步完善后满足监区定位范围要求。

The research of the prisoner's position based on Zigbee
Abstract
As the number of prisoners is increasing, position plex. Many crimes are of high educational background and active thinking. Due to the fault of prison supervision, the criminals will escape at night or in such bad weather like a rainy or foggy day. The traditional management style depending on manual prevention with camera surveillance has been unable to meet the requirements of modern prison management.
An overall design scheme of the prison positioning is put forward after the summarizing of background, meaning and progress at home and abroad. Firstly, two typical routing protocols are introduced. Through NS2 simulation tool, packet delivery ratio and normalized routing overhead and performance of two routing protocol are simulated pared. The AODV routing protocol is adopted in the harsh environment at last. Secondly, t
