摘要
射频识别技术(RFID)是最近几年来发展最快的非接触自动识别技术,无论在理论上,还是在实际应用都非常理想。尤其是超高频(UHF)RFID技术,它具有读取距离远、识别速度快、识别多标签能力强等优点,广泛应用于高速公路不停车收费、物流管理、肉食品安全方面的货源跟踪、门禁考勤管理、机密文件管理等领域。文章以嵌入式技术为研究背景,结合软硬件开发平台,给出了一种基于ARM和Linux的超高频读写器设计思路。
In recent years, radio Frequency Identification （RFID） has been grown with fastest speed. And it has get more and more ideal result both in theoretical research and application. Among RFID technologies, ultra-frequency （UHF） RIFD has many advantages such as it can read data in long distance, and can identify many kinds of labels with fast speed. Because of its superiority, UHF RIFD has been used in many fields such as in non stop charging in highway, logistics,management, supply tracking of meat food salty, access control attendance, and confidential document management. Under the background of embeded technology, in a platform of software and hardware development, a design method of linux ultra-frequency reader based on ARM is provided.
