摘　　要：针对特殊区域对于人员的进出管理和精确定位的需求,设计一款智能半有源射频识别标签。当标签进入事先安放好的线圈之内时被激活,从而与附近的读卡器进行通信,实现定位管理。标签的设计采用德州仪器公司生产的超低功耗MSP430系列单片机控制Nordic公司生产的无线信号收发模块NRF24L01来实现2.4GHz信号的发送。通过对标签的测试表明此设计可以实时发送精确定位管理信息,系统功能稳定,且在2.4GHz频段下信号的覆盖范围和较强的抗干扰能力更加适合这种对人员管理有特殊需求的环境。In this paper,intelligent semi-active RFID tags are designed to use in special areas due to access management and precise positioning requirements.Tags are activated when placed with-in pre-labelled circles to communicate with a nearby reader,and therefore positioning manage-ment is achieved.Label is designed to send 2 .4 GHz signal by using TI production of ultra-low power MSP430 series MCU to control NORDIC wireless signal transceiver module production NRF24L01 .Label testing show that this design can send real-time location management informa-tion accurately and system function is stable.Under the 2 .4 GHz spectrum signal coverage and strong ability of anti-j amming are more suitable for this kind of environment with special needs for personnel management.
