摘要
相比无源RFID标签,有源电子标签具有传输距离远、数据速率高、多标签识别速度快及处理能力强等诸多优点,因此,在远距离RFID系统如冷链物流等应用场合有着天然的优势。文章基于nRF24LEl芯片进行了有源电子标签的硬件设计,并参照ISO 18000-7标准设计了一套可实现自定义通信协议,定义了RFID读写器与有源标签通信规则,对于我国有源RFID标签技术发展具有一定作用。
Compared to the passive system,the active elctronis RFID system has features of long communication distance,fast data rate,fast multi-tag identification speed and high processing capability,therefore,possesses a natural advantage in long-range RFID system such as cold chain logistics application.This paper makes a hardware design of active electronic tag based on nRF24LEl chip.With reference to ISO 18000-7 standard,designs a custom communication protocol,and defines the communication rules of RFID readers and active tags,which helps to the development of active RFID tag technology.
