【摘要】 射频识别(Radio Frequency Identification,RFID)技术是从上世纪80年代走向成熟的一项自动识别技术,近年来发展十分迅速。本论文首先充分分析了RFID技术的特点,在其基础之上指出了其独特的优势,讨论了该技术在不同领域的应用。并针对RFID技术中面临的核心问题——防冲撞算法进行了分析,并且对目前应用最广,受关注最多的两类防冲撞算法:ALOHA算法和二进制搜索算法进行了详细的分析。利用MSP430F2012和nRF24L01分别作为MCU和RF芯片设计并实现了RFID系统中有源电子标签的硬件部分,软件部分实现了数据的发送和接受,然后通过测试验证了其模块的正确性。并且对基本ALOHA算法在设计的硬件平台上进行了设计。最后对未来的工作进行了展望,提出了以后可以进行的硬件和软件部分的修改和完善的建议。更多还原

【Abstract】 RFID （Radio Frequency Identification） is a kind of auto-identify technique risen in 90^th. It is very hot in theory and application research. It has a promising future.Firstly, we analyze the characteristic of RFID technology, and then based on that we point out its special advantage and different application in different fields. We also analyze the anti-collision algorithm which is the core of RFID technology andparticularly we analyze the two kinds of anti-collision algorithm——ALOHAalgorithm and binary search algorithm, which are paid attention to mostly.We design and implement the hardware part of an active electronic tag in RFID system with the MSP430F2012 as our MCU and nRF24L01 as our RF chip, and for the software part of that tag we could send and receive data with it and we have confirmed that function via some tests. For the anti-collision algorithm we design the software with the ALOHA algorithm based on our hardware. Finally, we point out the research orientation in the future and give the suggestion how to modify the hardware and software.更多还原
