摘要: 伴隨著無線通信技術的飛速發(fā)展,射頻技術越來越普及以及人們對智能化的要求更加高,從而導致中遠距離的產(chǎn)生。本文主要介紹了中遠距離RFID的技術優(yōu)勢和發(fā)展狀況。詳細介紹了中遠距離射頻的開發(fā)過程及相應的技術標準。 中遠距離射頻的基本的工作原理是利用C8051F320低功耗和NRF24L01射頻收發(fā)芯片實現(xiàn)10米以內中遠距離身份識別。當標簽離終端十米以內時會發(fā)送一個密碼就給終端,終端接收到時會相應LCD和PC上顯示標簽的主人詳細信息。 關鍵詞:中遠射頻 RFID NRF24L01 2.4G射頻技術
Abstract: With the rapid development of wireless communication technology, radio frequency technology is becoming increasingly popular, and people demand more highly intelligent, resulting in the generation of long-distance. This paper describes the advantages of long-range RFID technology and development. Details the development process in the long-range radio frequency and the corresponding technical standards. The basic long-range radio works is the use of low power consumption and NRF24L01 C8051F320 chip RF transceiver in the 10 meters distance identification. Less than ten meters away from the terminal when the tag will send a password give terminal, the terminal will receive the appropriate display label on the LCD and the PC owner for more information. Keywords: COSCO RF RFID NRF24L01 2.4G RF technology
目前常用的射頻自動識別技術中,條碼磁卡的成本較低,但都容易磨損,且數(shù)量很小;接觸式IC卡的價格高,數(shù)據(jù)的存儲容量較大,安全性好,但也容易磨損,壽命短;而射頻實現(xiàn)免接觸式操作,應用便利,無機械磨損,壽命長,無需可見光源,抗污染能力和耐久性強,而且可以在惡劣環(huán)境下工作,對環(huán)境要求低,讀取距離遠,無需與目標接觸就可以獲得數(shù)據(jù),無需重新制作新的標簽,可重復使用,并且使用防碰撞技術,能識別高速運動物體并同時識別多個卡。
