【摘要】：隨著監(jiān)獄關(guān)押犯人的數(shù)量不斷增加，犯罪人員社會成分復(fù)雜，許多犯罪人員還是技術(shù)犯罪，思維活躍，加之監(jiān)獄的監(jiān)管不利，導(dǎo)致個別發(fā)生襲警越獄事件，對社會造成極其惡劣的影響。犯罪分子越獄會選擇深夜以及大雨大霧這樣的惡劣天氣，傳統(tǒng)的依靠人工預(yù)防加攝像頭監(jiān)控的管理方式，，已經(jīng)無法滿足現(xiàn)代監(jiān)獄管理的要求。 為了方便有效的防止犯罪分子的逃脫，提出了基于Zigbee技術(shù)定位網(wǎng)絡(luò)的搭建。首先給出了監(jiān)區(qū)囚犯定位系統(tǒng)總體設(shè)計和系統(tǒng)的工作原理。其次，對兩種典型的路由協(xié)議AODV和DSR進行仿真和分析，并通過NS2網(wǎng)絡(luò)模擬器對它們的分組投遞率和歸一化路由開銷性能進行了仿真和比較，最終我們選用AODV路由協(xié)議。最后，搭建了四個參考節(jié)點定位一個中心節(jié)點的Zigbee無線定位網(wǎng)絡(luò)，并通過網(wǎng)關(guān)節(jié)點把接收到的數(shù)據(jù)傳到上位機，其中網(wǎng)關(guān)與參考節(jié)點采用CC2430芯片，移動節(jié)點采用CC2431芯片。 通過模擬定位效果測試，結(jié)果表示，中心節(jié)點可在64mX64m范圍內(nèi)四個參考節(jié)點內(nèi)實現(xiàn)定位，平均定位誤差為2.2米，進一步完善后滿足監(jiān)區(qū)定位范圍要求。
[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.
