【摘要】：進入二十一世紀(jì)以后，我國監(jiān)獄警察系統(tǒng)在監(jiān)控上所使用主要技術(shù)防范手段以被動監(jiān)控為主，但目前犯罪分子的各種手段逐步升級高科技犯罪，對這樣的高科技犯罪分子確保對罪犯多方位多角度的監(jiān)控，，使用RFID射頻識別技術(shù)進行定位，可以及時預(yù)知和發(fā)現(xiàn)犯罪分子的行動軌跡，進而掌控犯罪分子的去向，方便第一時間抓捕。 本文采用一種RFID定位算法進行定位系統(tǒng)的核心步驟，在算法設(shè)計上采用了一定的改進，讓算法能夠更加適應(yīng)我國監(jiān)獄警察的監(jiān)控需求，在算法的基礎(chǔ)上進行基于有源RFID的罪犯位置定位系統(tǒng)的設(shè)計。 首先從總體上概述了基于有源RFID的罪犯位置定位系統(tǒng)的整體框架，對系統(tǒng)進行了準(zhǔn)確的定位。然后，本文描述了系統(tǒng)的總體設(shè)計方案，對基于TDOA算法下定位系統(tǒng)的實施進行了合理的分析和設(shè)計。在此基礎(chǔ)上，介紹了在設(shè)計開發(fā)的過程中所遇到的問題及其解決方案。其次，又分別概述了為系統(tǒng)所采用的各種有效的測試技術(shù)和該系統(tǒng)尚待改進的地方。最后，本文對系統(tǒng)的完成情況進行了回顧和總結(jié)，并對其今后的發(fā)展進行了展望。 最終實現(xiàn)對基于有源RFID的罪犯位置定位系統(tǒng)的設(shè)計，保證通過RFID的監(jiān)控追蹤系統(tǒng)滿足各級監(jiān)獄單位的需要。
[Abstract]:After entering the 21 century, the main technical measures used by the prison police system in our country to monitor and control are mainly passive surveillance, but at present all kinds of means of criminals are gradually upgrading to high-tech crimes. For such high-tech criminals to ensure multi-directional and multi-angle monitoring of criminals, the use of RFID radio frequency identification technology for positioning, can timely predict and discover the trajectory of criminals, and then control the whereabouts of criminals. It is convenient to catch in the first place. In this paper, a RFID localization algorithm is used to carry out the core steps of the positioning system, and some improvements are adopted in the algorithm design, so that the algorithm can more adapt to the monitoring needs of the prison police in our country. Based on the algorithm, a criminal location system based on active RFID is designed. Firstly, the whole frame of the criminal position location system based on active RFID is summarized, and the accurate location of the system is carried out. Then, the overall design scheme of the system is described, and the implementation of positioning system based on TDOA algorithm is analyzed and designed reasonably. On this basis, the problems encountered in the process of design and development and their solutions are introduced. Secondly, the effective testing techniques used for the system and the improvement of the system are summarized. Finally, the completion of the system is reviewed and summarized, and the future development of the system is prospected. Finally, the design of the criminal location system based on active RFID is realized, and the monitoring and tracking system of RFID is guaranteed to meet the needs of all levels of prison units.
