【摘要】：近年来,射频识别(RFID)技术发展较快,这项技术在物流、制造、公共信息服务等行业得到了广泛的应用。在RFID技术的基础上发展起来的近场通信(NFC)技术则被更多的应用到了手机上。电子标签是这两项技术中必不可少的组成部分,它作为数据的载体可被阅读器读取。在当今的市场上,电子标签的种类与功能都较为单一,无非是先将各种信息以各种形式存储起来,之后再被读取出来。本文主要介绍了一种新型的柔性电子标签的设计与实现,这种电子标签可以实现可视化电子防伪的功能,这种防伪方式不同于传统的光学防伪,具有寿命长、可靠性强、稳定性高等优点。它主要由天线、柔性芯片、电致变色显示三部分构成,天线用来接收电磁波,芯片将电磁波处理好后可将电致变色显示驱动,通过这种方式就可以实现可视化电子防伪。本文首先介绍了传统电子标签的各个组成部分,详细分析了天线的各种参数,芯片的结构与工作原理,然后在传统电子标签的基础上,提出了一种具有可视化防伪功能的电子标签以及在实现过程中遇到的各种问题与解决方法。本文按照在设计与实现过程中的先后顺序,介绍了电致变色显示的结构与基本原理,随后介绍了柔性防伪芯片的制备,以及在制备过程中所使用的仪器与材料。然后又介绍了这种新型柔性电子标签的几种驱动方式,着重介绍了一种自主设计的便携式13.56MHz射频发射器,使用这种发射器可以很好的驱动我们的新型柔性电子标签。随着NFC技术的发展,使用手机驱动新型柔性电子标签变成了现实,这又大大简化了它的驱动过程。最后,展示了制作完成后的新型柔性电子防伪标签,并根据它的现有不足提出了下一代产品的设计方案与市场展望。因为专业硕士的要求,柔性芯片部分是与企业合作研发的,所以不能透露过多细节,请谅解。本项目主要针对在如今的商品市场中假货泛滥这一现状,而目前的防伪技术过于单一,已经跟不上不断增多的商品种类与不断增加的商品数量。本项目创新性的将可视化电子防伪的概念融入到电子标签当中,构成全新的电子防伪标签,它可以应用于绝大多数商品,如油盐酱醋等家用食材,烟酒等日常消费品,珠宝首饰等高端商品。这款产品能够帮助生产商在市场中塑造自己的品牌,提高品牌的知名度,也能够帮助消费者辨别真伪,从而避免买到假货,这无论对于生产商,还是对于消费者,甚至对于商品市场都是大有益处的。
[Abstract]:In recent years, radio frequency identification (RFID) technology has developed rapidly. This technology is used in logistics, manufacturing, Public information services and other industries have been widely used. The near field communication technology developed on the basis of RFID technology has been more applied to mobile phones. Electronic label is an essential part of these two technologies. It can be read by readers as a carrier of data. In today's market, the types and functions of electronic tags are relatively simple, simply by storing all kinds of information in various forms. This paper mainly introduces the design and implementation of a new flexible electronic tag, which can realize the function of visual electronic anti-counterfeiting, which is different from the traditional optical anti-counterfeiting. It is mainly composed of antenna, flexible chip and electrochromic display. The antenna is used to receive electromagnetic wave, and the chip can drive the electrochromic display after processing the electromagnetic wave. In this way, visual electronic anti-counterfeiting can be realized. Firstly, each component of traditional electronic tag is introduced in this paper, and various parameters of antenna, structure and working principle of chip are analyzed in detail. Then, on the basis of the traditional electronic label, this paper puts forward a kind of electronic label with visual anti-counterfeiting function, as well as various problems and solutions encountered in the process of implementation. This paper introduces the structure and basic principle of electrochromic display, then introduces the preparation of flexible anti-counterfeiting chip, the instruments and materials used in the preparation process, and then introduces several driving modes of this new flexible electronic label. This paper mainly introduces a portable 13.56MHz radio frequency transmitter, which can drive our new flexible electronic tag very well. With the development of NFC technology, using mobile phone to drive the new flexible electronic tag becomes a reality. This greatly simplifies its driving process. Finally, it shows the new flexible electronic anti-counterfeiting label after production, and puts forward the design plan and market prospect of the next generation product according to its existing shortcomings. The flexible chip part is developed in cooperation with the enterprise, so we can't disclose too many details, please understand. This project is mainly aimed at the situation of the proliferation of fake goods in today's commodity market, and the current anti-counterfeiting technology is too single. This project innovatively integrates the concept of visual electronic security into the electronic label to form a brand new electronic anti-counterfeiting label. It can be used in the vast majority of goods, such as household ingredients such as soya sauce and vinegar, daily consumer goods such as tobacco and wine, and high-end goods such as jewelry. This product can help manufacturers shape their own brands in the market and increase their brand awareness. It can also help consumers identify authenticity and thus avoid buying fake goods, which can be of great benefit to producers, consumers, and even commodity markets.
