摘要现在社会生活水平不断提高，零售业不断地发展，世界上的货物总量不断地上涨，传统的条形码信息量小，依赖数据库，易污损的缺点，难以满足现实需要。而RFID标签的抗污损能力，可读写，可同时读取多个标签，无屏障阅读等优点，可以很好地解决这个问题。超市仓库大量货物的进货出货和正常的库存盘点用最新的非人工数据采集，全自动化的实现大大提高了录入数据的准确性和快速有效性。87035

本设计采用ISO 15693协议标准，对符合15693协议标准的RFID标签可进行读写操作，并且在显示界面显示想要写入的数据并且显示读出的数据。本设计分为RFID读写器硬件和软件两大模块。

本文首先简单介绍了射频识别技术，紧接着对读写器硬件系统的射频模块、控制处理模块、天线和标签芯片进行了介绍，最后介绍读写器软件模块，射频识别(RFID)系统遵循的ISO 15693 协议标准，通讯协议，防碰撞协议，密钥修改等软件模块进行了分析，最后是整个应用设计的实验测试分析。

Abstract As the standard of living constantly boosts and retailing sector develops, the total amount of goods in the world is continuously rising。 However, traditional bar coda only contains little information, rely excessively on the database and it can be easily defaced, which make it difficult to meet the actual needs。 On the other hand, RFID is a perfect solution to the above-mentioned problems since it possesses many merits such as the anti-fouling ability, read-write feature as well as the capacities of simultaneous multiple tags reading and the screen-free reading。 Shipping statistics of a large number of goods in the supermarket and regular inventory counts are collected automatically, greatly improving the accuracy and efficiency of the data input。

Adopting ISO 15693 protocol standard, this design can read and write RFID tags that are up to this standard。Finally, the data to be written and read is shown on display interface。 The design for RFID reading and writing device is pided into two modules, namely hardware and software modules。

Firstly, this paper briefly introduces the RFID technology, followed by the introduction of reading and writing of the RFID module of the hardware system,the control processing module, antenna and the tag chip。 The following part is about reading and writing software module, radio frequency identification (RFID) system that accords with the ISO 15693 standard protocol, the communication protocol, anti-collision protocol, modification nof encryption keys and other software modules。At last, it is the experiment test and analysis of application design。

Keywords: RFID; RFID tag; Reader; ISO 15693 protocol standard; Anti collision
