基于MSP430控制的射频识别读写器设计(英文)

Design of RFID Reader Based on MCUMSP430

设计了一种基于单片机处理器的射频识别(RFID)便携式读写器的系统.采用当前先进的片上系统(SystemonChip,SOC),将外围电路尽可能地放置于SOC芯片内,利用软件实现了对射频标签信号的数字实时采集和控制功能,从而简化了传统的微控制器控制的RFID读写器所需的庞大硬件电路及其引入的额外误差,具有重要的实用价值,并且功耗和成本很低.

Saving power is an important problem in portable device. This paper presents a SOC （System on a Chip） system for radio frequency identification （RFID） reader to simplify the complex traditional circuits. It puts the peripheral circuits into SOCand uses software to execute the decoding, checking, identifying and real-time calculating and displaying of digital signals. The proposed system has advantages such as simple structure, low cost, and low power consumption.
