一种应用在宠物身份识别中的RFID阅读器的开发

DEVELOPMENT OF RFID READER APPLYING TO THE IDENTIFICATION OF PET'ID

针对当前城市小区宠物数量越来越多,所带来的社会问题日益严重,利用传统方法已经无法实现数量庞大的宠物群体的有效监控。介绍了基于U2270B射频芯片和FreescaleMCU用于宠物身份识别的RFID阅读器的设计。在介绍宠物管理标签系统的特点后,通过阅读器软硬件设计,详细阐述了125KHz、134KHz的双频选择和嵌入式手持设备低功耗以及记录存储等功能的实现。

The traditional method can.no longer effectively monitor enormous pet population, and the social problems incurred from growing pets in city uptowns become more serious than before. This paper introduces the design of RFID reader applying to pet-identification, which is based on radio frequency ship-U2270B and Freescale MCU. After brief introducing the features of pet tags administration system, it discusses in detail in the article the functions expanding on the design in both software and hardware including dual-frequency choice between 125KHz and 134KHz, low power consumption of the embedded handheld devices and records storage.
