【摘要】：进入二十一世纪以后，我国监狱警察系统在监控上所使用主要技术防范手段以被动监控为主，但目前犯罪分子的各种手段逐步升级高科技犯罪，对这样的高科技犯罪分子确保对罪犯多方位多角度的监控，，使用RFID射频识别技术进行定位，可以及时预知和发现犯罪分子的行动轨迹，进而掌控犯罪分子的去向，方便第一时间抓捕。 本文采用一种RFID定位算法进行定位系统的核心步骤，在算法设计上采用了一定的改进，让算法能够更加适应我国监狱警察的监控需求，在算法的基础上进行基于有源RFID的罪犯位置定位系统的设计。 首先从总体上概述了基于有源RFID的罪犯位置定位系统的整体框架，对系统进行了准确的定位。然后，本文描述了系统的总体设计方案，对基于TDOA算法下定位系统的实施进行了合理的分析和设计。在此基础上，介绍了在设计开发的过程中所遇到的问题及其解决方案。其次，又分别概述了为系统所采用的各种有效的测试技术和该系统尚待改进的地方。最后，本文对系统的完成情况进行了回顾和总结，并对其今后的发展进行了展望。 最终实现对基于有源RFID的罪犯位置定位系统的设计，保证通过RFID的监控追踪系统满足各级监狱单位的需要。
[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.
