文档介绍：基于RFID的仓储系统设计(硬件)
摘要
射频识别技术(RFID),即利用射频信号通过空间耦合实现无接触信息传递并通过所传递的信息达到识别目的的技术,是从20世纪80年代发展起来的一项自动识别技术,是无线电技术在自动识别领域中的具体运用。近年来,RFID技术的研究和应用在世界范围内得到了快速发展。
本设计采用了Nordic公司最新的低功耗无线射频收发芯片nRF24LE1,该芯片在一个极小封装(5mm×5mm)、增强型51高速单片机、丰富的外设接口SOC芯片,性价比高,。
本文的主要研究工作基于RFID技术的仓库管理系统的硬件部分的具体设计以及软件部分的简要介绍。系统的硬件电路主要分为电源、电子标签电路、阅读器电路、串口转换电路。该硬件系统在室内的传输距离可达30~40米,室外的传输距离可达100~200米。

The Design of Storage System Based on RFID
ABSTRACT
Radio Frequency Identification (RFID), using radio frequency signal to implement non-contact information transmission through Spatial coupling and pass the message to identify the purpose of technology, 80 years from the 20th century, developed an automatic identification technology, radio technology in the field of automatic identification of the specific application. In recent years, research and application of RFID technology in the world has been rapid development.
This design uses the nRF24LE1 of Nordic's latest low-power wireless RF transceiver chip, integrated in a small package(5mm×5mm), including wireless transmission antenna, enhanced high-speed 51 MCU, rich peripherals and the interface of the SOC chip, Cost-effective, it is suitable for a variety of product design and development.
This paper describes the RFID-based warehouse management system, the specific design of hardware and software parts of the brief. The system hardware consists of power supply, electronic label circuit, reader circuit, serial conversion circuit. The hardware system in the transmission range of up to 30 ~ 40 meters, outdoor transmission range of up to 100 ~ 200 meters.
KEY WORDS: nRF24LE1, radio frequency identification technology, reader, electronic tags
