【摘要】：最近幾年，監(jiān)獄安全事故頻發(fā)，給國(guó)家和人民的財(cái)產(chǎn)造成巨大的損失。建立一套完整的精確度高的監(jiān)獄人員精確定位系統(tǒng)對(duì)監(jiān)獄的安全管理起著非常重要的作用。特別在預(yù)防越獄事件發(fā)生方面，監(jiān)獄人員精確定位是最有效的方法。隨著無(wú)線通信技術(shù)飛速發(fā)展，特別是UWB技術(shù)誕生后和以太網(wǎng)技術(shù)的飛速發(fā)展為監(jiān)獄人員定位系統(tǒng)開(kāi)辟了新的道路。UWB技術(shù)應(yīng)用于監(jiān)獄人員的精確定位系統(tǒng)具有低功耗、低成本、硬件實(shí)現(xiàn)較容易、定位精度高、可進(jìn)行三維精確定位等優(yōu)點(diǎn)。UWB信號(hào)抗干擾能力比較強(qiáng)，傳輸可靠性好。通過(guò)以太網(wǎng)技術(shù)將監(jiān)獄人員精確定位系統(tǒng)與監(jiān)控中心連接。精確定位的精確度與監(jiān)獄管理的安全性有效性密切相關(guān)，因此本論文提出監(jiān)獄服刑人員三維精確定位系統(tǒng)研究與設(shè)計(jì)。 本課題主要對(duì)基于UWB技術(shù)的室內(nèi)三維精確定位算法進(jìn)行研究與設(shè)計(jì)。首先，簡(jiǎn)單介紹并比較了目前幾種常用的無(wú)線技術(shù)。詳細(xì)描述了UWB技術(shù)的基本原理，包括UWB基本概念介紹以及與其他無(wú)線定位技術(shù)相比UWB無(wú)線定位技術(shù)的主要優(yōu)勢(shì)同時(shí)也給出了兩種常用的UWB信號(hào)產(chǎn)生方式。其次，介紹了幾種現(xiàn)今主流的室內(nèi)定位算法以及其幾何模型。目前較好的定位算法是TDOA算法。針對(duì)于此算法的數(shù)學(xué)迭代公式是泰勒級(jí)數(shù)迭代算法，泰勒迭代的問(wèn)題在于初值的選取，如果初值選取不當(dāng)將會(huì)使收斂速度大大降低甚至不收斂。針對(duì)以上問(wèn)題本課題提出并設(shè)計(jì)了TOF/TDOA算法，使TOF的結(jié)果作為T(mén)DOA泰勒算法的初值進(jìn)行迭代運(yùn)算，優(yōu)化了收斂速度，在工程上也更容易實(shí)現(xiàn)。 論文最后對(duì)提出的新算法進(jìn)行了編程仿真，實(shí)驗(yàn)結(jié)果證明，，TOF/TDOA協(xié)同算法在很大程度上提高了定位精度，而且易于工程實(shí)現(xiàn)，在室內(nèi)三維精確定位領(lǐng)域有較為客觀的利用價(jià)值。
[Abstract]:Prison security incidents have occurred frequently in recent years. The establishment of a complete set of accurate positioning system for prison personnel plays a very important role in the security management of the prison. Especially in the prevention of prison escape incidents. . Accurate location of prison personnel is the most effective method. With the rapid development of wireless communication technology. Especially after the birth of UWB technology and the rapid development of Ethernet technology, it has opened a new way for the location system of prison staff. The application of .UWB technology to the precise positioning system of prison personnel has low power consumption and low cost. The hardware is easy to realize, the positioning accuracy is high, and so on. The anti-jamming ability of UWB signal is relatively strong. The transmission reliability is good. The precise positioning system of prison personnel is connected with the monitoring center by Ethernet technology. The accuracy of precise positioning is closely related to the security and effectiveness of prison management. Therefore, this paper puts forward the research and design of three-dimensional precise positioning system for prison inmates. This paper mainly focuses on the research and design of indoor 3D precise location algorithm based on UWB technology. First of all. This paper briefly introduces and compares several commonly used wireless technologies, and describes the basic principle of UWB technology in detail. Including the introduction of the basic concept of UWB and the main advantages of UWB wireless positioning technology compared with other wireless positioning technology, two common UWB signal generation methods are also given. Secondly. This paper introduces several main indoor localization algorithms and their geometric models. At present, the better localization algorithm is the TDOA algorithm. The mathematical iterative formula for this algorithm is Taylor series iteration algorithm. The problem of Taylor iteration is the selection of initial value, if the initial value is not selected properly, the convergence speed will be greatly reduced or even not convergent. This paper proposes and designs a TOF/TDOA algorithm for the above problems. The result of TOF is iterated as the initial value of TDOA Taylor algorithm, the convergence rate is optimized, and it is easier to realize in engineering. Finally, the new algorithm is programmed and simulated. The experimental results show that the TOF / TDOA collaborative algorithm improves the positioning accuracy to a large extent and is easy to be implemented in engineering. In the field of indoor three-dimensional accurate positioning, it has more objective use value.
