【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，其中网关与参考节点采用CC2430芯片，移动节点采用CC2431芯片。通过模拟定位效果测试，结果表示，中心节点可在64mX64m范围内四个参考节点内实现定位，平均定位误差为2.2米，进一步完善后满足监区定位范围要求。
[Abstract]:With the increasing number of prisoners in prison and the complexity of the social composition of the criminals, many of the criminals are still technically criminal and active in thinking, coupled with the unfavourable supervision of the prison, resulting in individual attacks on police escapes. Have an extremely bad effect on society. Criminals escape from prison in bad weather such as late at night and heavy rain and fog. The traditional management method, which relies on artificial prevention and camera monitoring, can no longer meet the requirements of modern prison management. In order to prevent criminals from escaping effectively, a Zigbee based location network was proposed. Firstly, the overall design and working principle of the prisoner positioning system in the prison area are given. Secondly, two typical routing protocols, AODV and DSR, are simulated and analyzed, and their packet delivery rate and normalized routing overhead performance are simulated and compared through NS2 network simulator. Finally, we choose AODV routing protocol. Finally, the Zigbee wireless location network of four reference nodes is built to locate a central node, and the received data is transmitted to the host computer through the gateway node. The gateway and reference node use CC2430 chip, and the mobile node uses CC2431 chip. The results show that the central node can be located within four reference nodes within 64mX64m, with an average positioning error of 2.2 meters.
