Research On RFID Technology And Degign And Implementation Of Active Electronic Tag

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.
