UHF-Reader通信协议

UHF超高频RFID标准详解空中接口协议（物理层、MAC层）超高频RFID空中接口协议1RFID系统组成RFID(RadioFrequencyIdentificatiON)的基本原理就是将电子标签安装在被识别的物体上，当被标识的物体进入RFID系统的阅读范围时，射频识别技术利用无线电波或微波能量进行非接触双向通信，来实现识别和数据交换功能。

标签向读写器发送携带信息，读写器接收这些信息并进行解码，通过串口将读写器采集到的数据送到后端处理，并通过网络传输给服务器，从而完成信息的全部采集与处理过程，以达到自动识别被标识物体的目的。

RFID应用系统的架构如图1所示，基本由阅读器，天线和标签组成，另外还有后台的企业应用系统。

标签和读写器之间通过耦合元件实现射频信号的非接触耦合。

系统中有一个中间件负责完成系统与多种阅读器的适配，过滤阅读器从标签获得的数据，以减少网络流量。

标签与读写器之间通过空中接口协议进行通讯，读写器与中间件之间的通信通过读写器协议进行定义，中间件与应用系统之间的通信接口由ALE协议规定。

图2为RFID系统阅读器和标签之间的通信过程。

读写器和标签通过射频电磁场进行数据交换。

阅读器首先发送连续载波信号，通过ASK调制等方式发送各种读写命令，标签通过反向散射调制的方式响应阅读器发出的命令，返回EPC(电子产品编码)等信息。

2空中接口协议如图1所示，RFID系统涉及的协议从底层通讯到上层应用都有各自的规范，根据标签的供电方式不同，RFID系统可分为有源系统和无源系统两种;根据系统工作的频段不同，可分为低频，高频，超高频和微波频段的RFID系统。

论文主要讨论超高频段无源RFID空中接口协议部分的关键技术。

当前超高频RFID空中接口协议主要是ISO18000-6TYPEB协议和EPCGlobalClass1GEN2协议(EPCC1GEN2协议，现已经成为ISO18000-6TYPEC)。

两种协议的对比如表1所示。

实验二、HF高频RFID通信协议一、实验目的1.1 掌握高频读卡器的通讯协议1.2 掌握本平台高频模块的操作过程1.3 掌握高频模块工作原理二、实验设备硬件：RFID实验箱套件，电脑等。

软件：Keil，串口调试助手。

三、实验原理2.1高频RFID系统典型的高频HF（12.56MHz）RFID系统包括阅读器（Reader）和电子标签（Tag，也称应答器Responder）。

电子标签通常选用非接触式IC卡，全称集成电路卡又称智能卡，可读写，容量大，有加密功能，数据记录可靠。

IC卡相比ID卡而言，使用更方便，目前已经大量使用在校园一卡通系统、消费系统、考勤系统、公交消费系统等。

目前市场上使用最多的是PHILIPS的Mifare系列IC卡。

读写器（也称为“阅读器”）包含有高频模块（发送器和接收器）、控制单元以及与卡连接的耦合元件。

由高频模块和耦合元件发送电磁场，以提供非接触式IC 卡所需要的工作能量以及发送数据给卡，同时接收来自卡的数据。

此外，大多数非接触式IC卡读写器都配有上传接口，以便将所获取的数据上传给另外的系统（个人计算机、机器人控制装置等）。

IC卡由主控芯片ASIC（专用集成电路）和天线组成，标签的天线只由线圈组成，很适合封状到卡片中，常见IC卡内部结构如图2.1所示。

图2.1 IC卡内部结构图较常见的高频RFID应用系统如图2.2所示，IC卡通过电感耦合的方式从读卡器处获得能量。

下面以典型的IC 卡MIARE1为例，说明电子标签获得能量的整个过程。

读卡器向IC 卡发送一组固定频率的电磁波， 标签内有一个LC 串联谐振电路（如图2.3），其谐振频率与读写器 发出的频率相同，这样当标签进入读写器范围时便产生电磁共振，从而使电容内有了电荷， 在电容的另一端接有一个单向通的电子泵， 将电容内的电荷送到另一个电容内储存，当储存积累的电荷达到2V 时，此电源可作为其他电路提供工作电压，将标签内数据发射出去或接 收读写器的数据。

技术参数⼯作频率中国(920MHz~925MHz)、韩国(917MHz~924MHz)、美国(902MHz~928MHz)、欧洲(865MHz~968MHz)、⽇本(916MHz~924MHz)协议ISO 18000-63(6C)/EPC Gen2⼯作⽅式Frequency Hopping or LBT (Listen-Before-Talk)调制⽅式DSB-ASK编码⽅式Miller 2, 4, 8 and FM0通信接⼝UART读写距离10cm功能与特点可设置标签到读写器的编码⽅式与通信速率。

可设置EPC C1 G2协议的SELECT命令与QUERY命令的参数。

⼆、软件安装第⼀步：双击CP210x_VCP_Win_XP_S2K3_Vista_7.exe，安装串⼝驱动。

然后把读写器与电脑⽤USB 线连接。

右击我的电脑属性查看端⼝，新增⼀个串⼝号（COM3），此串⼝号与电脑有关，不同电脑新增串⼝号不⼀样，记下串⼝号，后⾯⽤到。

第⼆步：双击/doc/8a76346a10661ed9ad51f3b0.html .exe 安装本软件运⾏需要的库 .net 4.0。

若电脑已经安装过，就跳过此步骤。

第三步：打开软件，此软件不需安装，可直接运⾏。

此软件⽤于读写标签与设置读写器的参数。

1、串⼝选择按下扫描可⽤串⼝按钮，可以扫描到当前可⽤的串⼝，选择在设备管理器⾥新增的相应的串⼝。

没有⾃动打开串⼝功能，需要⼿动正确选择串⼝，⼀般为COM3，不同电脑不⼀样，请正确选择。

2、标签的查询与读写1）选项卡选EPC C1 G2 Test可以设置查询次数，Inventory round 即为⼀个查询周期，具体参看EPC C1 G2标准协议。
