Wu Yueshan 2006 China International RFID Technology Application Forum speech

[host] the last speaker is Mr. Wu Yueshan, deputy leader of the RF working group of China Association of automatic identification technology. Mr. Wu graduated from Northwestern Polytechnic University and is mainly engaged in the research and development of electronic information. At present, he has multiple identities. He is also a professor of Northwestern University. At present, he is also the technical director of Shenzhen Yuanwang Valley and has participated in many investigations and research projects. In addition, today's forum is jointly organized by China coding center and China automatic identification Association, which is a national first-class Association. Thank you for your hosting in bar code and automatic identification technology for many years. Objectively speaking, we are just doing something. The title of my report is the research on RFID technology standards. It should be emphasized here that we are studying standards, not publishing or formulating standards. In fact, what kind of work have we done in this regard? In the process of doing this work, what problems have we thought about, what problems are involved, what problems we face, what things have been done, and what things we plan to do in the future? Take this opportunity to report to you

this report is roughly divided into six parts. One is about the basic understanding of the standard system. The second part is the current situation of RFID standards from our perspective. Third, the development market space is as high as trillion; The second part introduces the work of the radio frequency working group of China Association of automatic identification technology. The fourth part introduces our main work goal this year, which is the specific formulation of a standard on the technical specifications of RFID readers and tags. The fifth aspect is to focus on some follow-up work. Finally, there are some points of view

first of all, let's look at the first problem, which is about the understanding of the standard system. Let's introduce it from three levels. From the perspective of layering, RFID technology is the technology. Technical standards, technical patents, technical products, technical integration, and technical applications may be indispensable for a mature industry at present. In the industrial chain, products are the most basic. The product will involve some patents, which may be further incorporated into the standard. If products are to be applied, they must be implemented through integration and engineering, which is probably such a relationship. In terms of technical standards, it is at the highest level, that is, overlooking the overall situation, there is such a commanding height and the role of technology convergence. Of course, this standard should be recognized by everyone, otherwise it is also a useless standard

considering the issue of standards, if you don't enter this aspect and carry out specific work, you may directly feel that it is very high and important, but more aspects may not be clear. From our point of view, this problem probably involves these levels. One is as a standard, it is a system, this standard is not out of thin air, is developed. The formulation of this standard requires a working platform. This work platform should have a centralized management and control. Next, this standard system should have some leaders, namely core workers and participants. Through these levels, we can show you a complete standard complex system, including the formulation process

from the perspective of the characteristics of the standard system, there are international relevant standardization organizations in the world and domestic relevant standardization organizations in the country. From the perspective of standard classification, it may be divided into technical standards, management standards and working standards. This is a system. The concept of this aircraft is part of the innovative product jointly proposed by Paul Allen, the co founder of Microsoft, and Burt Rutan, the founder of "plastic composites company". It still has small dielectric constant and dielectric consumption in the high frequency range. Of course, what you are most concerned about, and at present, is probably the technical standards, which are aimed at physical objects. First, make clear the physical objects, and then see how the physical objects are managed, applied and implemented; In fact, technical standards are also hierarchical. From the perspective of understanding, we can regard them as some basic standards. This is the lowest and most important. Once this is removed, there will be no place on it. There are also some links between the preceding and the following, and the last one is the application class. In this case, we will emphasize the characteristics of the standard layered system

here is a diagram of the basic situation of the international organization for standardization. From the perspective of international standardization organizations, there are international standardization organizations, regional standardization organizations, national standardization organizations, and industrial or industrial standardization organizations. This is sorted out according to the international standardization system, which can be roughly divided into these levels. The most famous organization for standardization is ISO, the international organization for standardization. What do I mean by 226 given at the back of this slide? Represents the ISO international organization for standardization, which now has 226 professional and technical committees. The professional technical committee is specialized in different aspects. There is also a standardization organization called IEC, which is the International Electrotechnical Commission. There are 110 professional committees below. Closely related to our RFID is a joint technical committee, called JTC1, which is divided into many committees. SC31 is directly related to RFID. Next, it is divided into working groups, which continue to be divided into SJ. This organization is also a hierarchical structure. This is a systematic process from coarse to fine, and then back again. Our country is sac, China Standardization Administration Committee and China Standardization Administration Bureau

let's take a look at the situation of China's international organization for standardization. China's sac, including relevant standardization institutions of various ministries and commissions, including institutions directly under the National Standards Commission, as well as provincial, municipal and local institutions, handles relevant standardization affairs. It is to formulate corresponding standards at different levels according to different objects

let's look at the current situation of RFID technology standards. RFID technology standard, we propose a concept of technology, standard, cost, such a cycle. It also puts forward a preliminary analysis of the status of this standard. Have a preliminary expectation for the development of technology. We divide this into three concepts, one is technology, one is standard, and the other is cost. The price of the products we care about depends on the cost. We are concerned about what standard this product meets and what specific technology this product adopts, such as RFID technology. In general, this is a concept. If it is broken down, it will be divided into many technologies. For example, according to frequency, there are low frequency ones, below 135KHz, typical 13.56 megahertz ones, 860 megahertz to 960 megahertz ones, 2.45 ones and 5.8G ones, These are the more popular frequency bands of RFID in the world. Without standardization, this product cannot be produced on a large scale, and cost reduction is also impossible. Without technological progress, it is difficult to improve standardization. Therefore, we regard it as a cycle. Standardization is driven by technological development. After standardization, the cost of this product decreases. We focus on one core, which is the application of RFID. After forming such a circle, if we combine it with the current development of RFID, such a closed circle may be completed by the end of this year. The first circle started in 2003, went through 03, 04 and 05, and went on until 2006. The first circle was basically completed internationally, but it still lagged behind a little at home. In the second round, we expect this standard to go another round, the technology will be improved again, and the cost will be reduced again. We expect it to go for two years. After two laps, it will basically mature, which may involve large-scale applications. At this time, it will turn faster. After three laps, it's almost done. Of course, it will turn faster and faster later, which will be combined with specific applications. After comprehensive analysis of standardization research and technology development, we have obtained such a judgment. Whether this judgment is right or not is tested by time

rfid application is the core. How can we use RFID as soon as possible? In fact, we should analyze calmly. Without analysis, there may be some blindness. It should be said that the application is the ultimate goal of RFID. In the application, the technology can be enriched and improved. This application looks very disordered, and it may be orderly if analyzed. At the beginning, applications that may not cost much may be in urgent need. They may come and be used first. For example, China's railway car number automatic recognition, which is also one of the two suppliers of railway car number recognition, plays a great role in yuanwanggu company. This came quite early, and was fully launched and applied in China's railways in 2000. That is to say, it doesn't cost much, but this thing is urgently needed. What problem has it solved? When the train passes, the number of each carriage can be automatically unified, which is conducive to the management and scheduling of railway transportation. Without this technology, people used to stare with their eyes, which was very laborious. There is also the first step when the conditions are mature. This is to match the application requirements with the technology. For example, we have also promoted some projects, including pallets and coal trucks for electric fields. Now these projects are more and more, that is to say, if the requirements and technology are well matched, the application can be achieved quickly; There is also foresight. Knowing this thing can bring me great efficiency, or I can take the first step and have an advantage over others. If we want to start, it may be related to these three aspects. At present, Wal Mart's promotion has given everyone a strong pull, but when and how to start their own applications still involve a specific judgment. If you are not prepared, there will be many problems

it should be noted that the application of RFID is closely related to the application environment, especially in the early stage of technology and application. Unlike buying a TV, everyone can use it well after going back

rfid standard status can be described from different levels. There are air interface standards, test standards, relevant equipment standards, or application standards, continuity standards, and basic standards. On the right is the international standard division method. The middle part includes electronic tags and readers, which are the basic components of RFID, and which is also the object of standardization. The reader writer standard and electronic label standard that we will introduce later are the contents of this part. The status of RFID standards is also of great concern internationally. From the detailed division of technical standards, there are four kinds, which are divided into four parts, which are connected with each other. Including technical standards, data standards, testing and consistency standards, and relevant application standards. I won't talk about the details one by one. In terms of development, each standard has a focus and orientation. In detail, it is modern industry
