摘要
针对人们对特殊复杂环境下信息安全和人员管理的实际需求,而传统GPS定位技术在无法满足实时、高精度定位的问题,提出了一种基于半有源RFID技术的人员跟踪定位方法。设计并开发出的125 kHz低频激励器,激励半径1~10 m可调,激励区域边沿控制达到分米级。采用低频激励器、RFID阅读器和双频标签搭建的实验系统经过测试,系统稳定可靠,人员定位跟踪信息实时、准确。
Aiming at the practical needs for information security and personnel management under special complex environ- ment, a staff tracking and positioning method based on semi-active RFID technology is proposed because the traditional GPS po- sitioning technology can not meet the high-precision real-time positioning. A 125 Khz low-frequency exciter with adjustable exci- tation radius of 1～10 m and excitation region edge control of decimeter level was designed. The experimental system constructed by low-frequency actuator, RFID reader and dual-frequency RFID tags was tested. The test result show that the experimental sys- tem based on semi-active RFID technology is stable and its tracking information is real-time and accurate.
