Application of RFID technology in manufacturing and product

The RFID system consists of the following parts       ①电子标签,由芯片和标签天线组成,通过电感偶合或电磁反向散射原理与读写器进行通信。    The electronic tag is composed of a chip and a tag antenna, and is communicated with the reader through the inductive coupling or electromagnetic back scattering principle.       ②读写器,是读/写标签信息的设备,作为数据采集的终端,读写器还需要与中间件进行数据交换。    Read and write device is a device to read / write tag information. As the terminal of data acquisition, the reader needs to exchange data with the middleware.       ③天线,是为标签和读写器提供射频信号空间传播的设备。    An antenna is a device for providing a radio frequency signal space for a label and a reader.       ④中间件,是连接RFID设备和企业应用程序的纽带,也是RFID应用系统的核心。其原理是:首先给电子标签中的芯片写入代表产品唯一特性的信息,此信息被存入服务器的数据库。产品流通过程中当其接近读写器时,读写器发射电磁波给电子标签提供能量使其激活芯片,芯片将产品信息通过天线传递给读写器,读写器将接到的信息通过中间件传递给服务器,服务器经过处理再将信息传递给读写器从而完成对产品的确认。    Middleware is the link between RFID devices and enterprise applications, and it is also the core of RFID application system. Its principle is: first to the electronic tag chip to write on behalf of the unique characteristics of the product information, this information is stored in the server database. The product circulation process when it is near the reader, the reader emit electromagnetic waves to the electronic tag to provide energy to activate the chip chip, the product information through the antenna transfer to the reader, the reader will receive the information delivered to the server through the middleware server, after processing and then pass the information to read and write is to complete the confirmation of the product.       RFID的原理就决定了其安全性,因为标签的数据只是一个唯一编码,可以完全不加密,与这个唯一编码对应的代表特殊意义的数据存储于安全数据库中。当读取标签数据后,读写器将标签唯一编码发送至安全服务器,安全服务器对该请求进行安全验证后,搜索数据库并调出所需数据,数据由服务器加密后发送给读写器。这样,只要攻击者不能进入数据库,恶意获取的代码资料是没有任何意义的,不通过安全验证将得不到任何有用的信息,产品内容从而得到保护。    The principle of RFID determines its security, because the label data is only a unique code, can not be completely encrypted, and the unique code corresponding to the special meaning of the data stored in the security database. When reading the label data, the reader will be sent to the security label only encoding server, security server security verification of the request, search the database and call up the required data, data encrypted by the server sent to the reader. In this way, as long as the attacker can not enter the database, malicious access to the code information is of no significance, not through security verification will not get any useful information, product content to be protected.       RFID和条形码比较:条形码信息是可视化的,容易被复制。由于RFID承载的是电子信息,从而不容易被复制。目前国内市场上的防伪产品,所采用的防伪技术绝大部分仍然是在纸基材料上做文章,常见的防伪技术有:全息图案、变色墨水、产品和包装上面的隐蔽标记。这些技术不具备唯一性和独占性,往往致使一种防伪产品或技术出现后很快就会被复制,造成对防伪技术的伪造,防不胜防,也不能起到真正的防伪作用。RFID技术应用与防伪技术,其电子标签内植芯片并且内含全球唯一的代码或商品编码信息,该编码只能被授权的读写器所识别,同时标签内信息与读写器唯一编码一起通过通信网络发送到防伪数据库服务器进行认证,另外,当标签被损坏后信息将无法被读取,这将保护标签内内容不被窃取,从而达到防伪目的。    RFID and bar code comparison: bar code information is visual, easy to copy. Since the RFID is loaded with electronic information, it is not easy to copy. Security products on the domestic market at present, the vast majority of anti-counterfeiting technology is still in the paper-based materials, anti-counterfeiting technology are common: holographic patterns, ink, color and packaging products above the hidden mark. These techniques do not have the sole and exclusive, often resulting in a security product or technology will soon be copied, cause of forgery, anti-counterfeiting technology can not play impossible to guard against, the real security role. The application of RFID technology and anti-counterfeiting technology, the electronic tag chip plant and contains the unique code or commodity information encoding device, encoding the identification read only by authorized, at the same time in the label and reader only encoding information sent through the communication network security with the database server for authentication, in addition, when the label the damaged information will not be read, it will protect the content from being stolen in the label, so as to achieve the purpose of security.       瑞士钟表业防伪就采用了RFID技术。瑞士Winwatch公司致力于开发与申请智能化财产特许专利和将RFID技术运用于各种瑞士名表的解决方案特许专利权,考虑到金属表壳对天线频率接收所造成的影响,Winwatch公司将RFID标签镶入手表表面玻璃中进行手表的防伪、识别和追踪。这项技术在2003年已经得到了瑞士政府的认证。在生产过程中及产品生产时,通过手工或自动化的方法在产品的相对位置放置RFID防伪标签,或者将标签放在产品包装盒内。成品出厂前,在防伪RFID标签内写入该产品的订单号,生产日期,产品型号等有价值的信息,与RFID标签的旧号码结合,产生产品的唯一信息,同时可以进行加密处理,防止其他读写设备更改标签内的信息。布置在仓库门口的RFID系统自动采集数据,记录该批产品何时发往何地。    Swiss watch industry anti-counterfeiting using RFID technology. The Swiss Winwatch company is committed to the development and application of intelligent property patent and use RFID technology solutions in a variety of Swiss watch franchise rights, taking into account the metal shell on the antenna frequency caused by receiving the Winwatch company will be security, identification and tracking RFID tag inserted into the surface of the glass to watch watch. The technology has been certified by the Swiss government in 2003. In the production process and product production, through manual or automated methods in the relative position of the product placement RFID security labels, or the label in the product packaging box. The finished product, write the product order number, the security of RFID label production date, product type and other valuable information, old number labels and RFID combination, the only information products, at the same time can be encrypted to prevent other reader change information of tags. The RFID system which is arranged at the doorway of the warehouse collects the data automatically and records when to send the batch of products.       这样,产品实现正常销售,通过销售商或分销商,最终到达顾客手中。因为标签内信息在出厂写入过程中进行了加密处理,所以只有用厂家授权的读写设备才能读取标签内的加密信息。如果出现了伪劣产品在市场上进行销售的活动,销售人员使用手持式销售稽查PDA读取产品标签内的信息,即可确定该产品是否是该公司生产的产品,及时制止假冒产品流入销售网络。如:利用RFID技术实现的酒类防伪系统,是利用RFID技术软硬结合的方法实现防伪的,此种系统可用于带有瓶盖的容器商品防伪,通过瓶体结构设计和后台认证系统实现商品的防伪。系统有瓶盖内嵌的射频芯片,通过RFID读写器、通信网络和防伪数据库服务器,获得商品信息。防伪数据库服务器把芯片编码对应的生产日期、生产厂家、查询次数以及读写器编码对应的注册者等信息返回给RFID读写器,达到防伪认证的目的。最后当酒瓶被开启时,位于酒瓶瓶口的切割装置将切断天线和芯片的连接,致使RFID读写器无法读取该酒瓶盖顶部芯片的编码,而无法再被复制,从而有效地实现此类商品的防伪。    In this way, the product to achieve normal sales, through the seller or distributor, and ultimately reach the hands of customers. Because the information in the label in the factory written in the process of encryption, so only with the manufacturer's authorized read and write device can read the label encryption information. If there are fake products on the market, the sales staff using handheld sales inspection PDA read the information in the product label, you can determine whether the product is the company's products, timely stop counterfeit products into the sales network. Such as: Anti - counterfeiting system based on RFID technology, is a method to realize the combination of hardware and software by using RFID technology this system can be used for security, the anti fake bottle cap with a container, the bottle body structure design and backend authentication system realize the counterfeit goods. The system is equipped with a radio frequency chip embedded in the bottle cap, and the product information is obtained through the RFID reader, the communication network and the security database server. The security database server returns the corresponding date of manufacture, the manufacturer, the number of queries and the corresponding register of the reader to the RFID reader. Finally, when the bottle is opened, the connection is located in the bottle cutting device will cut off the antenna and the chip, the RFID reader can read the bottle cover top chip encoding, and cannot be copied, so as to effectively implement this kind of counterfeit goods.       我国的防伪技术经过了十几年发展,特别是最近几年的迅猛发展,已经达到了百亿元的市场规模,其绝对数值已经相当大了。如北京创羿科技有限公司等等。但是,从行业产    After more than ten years of development, China's anti-counterfeiting technology, especially the rapid development in recent years, has reached the market size of 10 billion yuan, its absolute value has been quite large. Such as Beijing Yi Technology Co. Ltd. etc.. However, from the industry
