Origin: RFID world network time: 2012-08-24

2012 shenzhen international academic development of the Internet of things industry BBS on August 16 6th floor narcissus hall was held at shenzhen convention &exhibition centre, from the ministry of industry, innovation committee held electronic society of China, shenzhen branch, shenzhen development and reform commission and national economic informatization commission, university researchers, executives and other well-known industry experts, scholars, veteran, a total of more than 500 people to attend.

All the experts gathered in shenzhen, China's Internet innovation strategy, business model and innovation, standard formulation and process, where the Internet of things industry construction, iot industrial park public platform for cooperation and other multi-angle deep discuss hot topics, such as the Internet of things industry development for China's Internet industry development.

Professor wang dong, secretary general of the Shanghai electronic label and iot, is speaking on the topic of "application of RFID and Internet of things". He's analyzing the relationship between RFID, the Internet of things and smart cities, and he thinks that many people say that RFID is equal to the Internet of things, which is all one-sided. Every technological vision of the Internet of things, like a blind man, sees only one part. When we add a view of the Internet of things, we can see a full view of the Internet of things, which is a complete understanding of the Internet of things. Here is the transcript:

Wang dong: it's a pleasure to talk to you today on BBS. My topic today is "RFID and Internet of things applications".

The first is the relationship between the RFID Internet and smart cities. I outlined a few questions:

The first question is what is the Internet of things. The eu lists the roadmap, which lists the main applications of the Internet of things. Qi director this morning from the planning point of view of things, but from the point of view we make iot technology people, and there are a lot of views, there is a picture of a view, make of the sensor to the wireless network communication technology also has a view, look at things from every Angle, from one side of the Internet of things to see, do not represent all of the Internet of things. Many people used to say that RFID is equal to the Internet of things. Every technological vision of the Internet of things, like a blind man, sees only one part. When we add a view of the Internet of things, we can see a full view of the Internet of things, which is a complete understanding of the Internet of things.

The second question is what is the fundamental feature of the Internet of things. The Internet of things now emphasizes integration and integration. The RFID industry has been looking forward to the idea that the industry will soon be able to do so if there is widespread use of RFID in logistics. To the Internet of things at this stage, our position can become wisdom logistics car, the car any goods can be labeled with RFID, through the GPS to see the current material goods. There are a lot of refrigerator box has a sensor, you can monitor the goods anytime and anywhere, the driver's cab has a camera, I can monitor who is anytime and anywhere with what method the cargo operation, the whole process in this way can the logistics supply chain visualization, this is the logistics industry dream state. And this state not by RFID can achieve alone, nor by the sensors can be implemented separately, is to put the RFID positioning technology, sensors, video image and so on a series of Internet of things technology for integrated and comprehensive.

Is there any innovation? As teacher ma also introduced, the Internet of things started with innovation. There's a company called the branch in Shanghai, you in any supermarket on the bar code of goods, take a photo, it immediately tell you the goods in wal-mart, carrefour, metro sell how many money.

It's not just a matter of business models, the Internet of things starts with original innovation. Like I was holding the RFID tag, all sensors of the Internet of things no one can say that the label market price is 4 hair, could this thing will be off half the price of a year, the price is very low. Many customers said the RFID tag is quite expensive, but there are some companies began to original innovation, the label cost is made up of several parts, in the middle of the chip and the outside antenna, the antenna of the subcontractor has three parts, it USES copper and aluminum materials, what I have in my hand is graphene, although not very stable, but represents a kind of direction, that is not made of copper and aluminum, the antenna but graphene material, so the price will reduce. We've come up with a low-cost label that drives our industry to innovate, and that's an innovation.

I do RFID myself, and a lot of manufacturers say you don't always say RFID, now it's the Internet of things and smart cities, you have to keep up with The Times, and we do keep up with The Times. Iot, RFID is the core technology of the Internet of things, from the RFID can to Internet of things, and the Internet of things in a higher level provide us with a stage, let the RFID technology and positioning technology, video monitoring technology, sensing technology integration in together, on a higher platform development the application of RFID industry.

Today many speakers are introduced the intelligent transportation, energy, wisdom, health, public security, government services, etc., and these applications cannot leave RFID Internet of things and cloud computing, the value of the value of it is not the technology itself, but in such technology included in all aspects of urban management, realize the intelligent transportation, medical, wisdom of public facilities, through the applications and services to reflect the value of the technology. The Internet of RFID and cloud computing is the means by which smart cities are implemented, and this will be clearer.

Part ii, RFID and the Internet of things applications.

Many of you are on the front line of the Internet of things, and we've covered a lot of applications, so what do we do with technology? Application mode and scheme may be their design and thinking in the process of business operation for a long time, we should cooperate together with them, use our technology to help them to achieve such a scheme. We should do RFID and the Internet of things applications to help them address a range of issues that arise in the process of applying RFID to the Internet. Many companies may be a series of technologies such as RFID iot itself a little knowledge, make a plan in the laboratory, make a plan after porous, look not to come out in the laboratory, a large field implementation problems appeared immediately, and constantly adjust at the scene, the customer's site as their learning stage, this is the wrong one way of doing this.

Liquor manufacturers, this is a practical, start with a wine with RFID tags, finishing to label the attached code, then read again, have a look at whether to write in, can be read out, even break out, can't read it, for we do a lot of RFID tags of the application of this is very positive, if all of the rare wine RFID tag, the application is very big. But after he put the label with the past, while on a field conduct reading rate is only 70% or 70%, ten bottles of wine may have two or three bottles with code with, or read yards out. We are a system integrator, we work in the company to build a and enterprises the scene like a line, in such a line through continuous testing to see what the label need to improve, which can not meet the requirement of the customer, and test, then adjust, through such a simulation environment, can turn a scene will appear in the implementation of 80% of the problems solved, this is the RFID iot industry special needs.

RFID application engineering clients focus on four issues: what is the performance of RFID? The second is the ability to reduce costs; The third is what you do in the field; Fourth, the issue of whether the problem can continue to provide services and support.

If you go to the convention hall, many companies use a wide variety of labels that are based on some kind of application. System integrator or the customer should choose suitable label according to the application environment, each kind of label is a commercial labels, each tag is designed according to certain applications, the shape of each tag completely different, such as chip is dozen, but antenna is multifarious, each antenna is designed according to some special applications. Why does the antenna grow in this shape? Theoretically, you can push a miniaturized antenna design, the label 900 million half wave antenna, the tag should be 16 cm long, can't stick on the bottle, so to miniaturization, twists and turns to do, and then will change, but also do the antenna gain. There are tags that extend the width of the fit, so they also expand the bandwidth. The impedance of the chip and the antenna should match each other, and that's when the tag reads the maximum distance and the best.

Each type of tag is designed to meet the needs of some kind of application through a series of designs, so what should we do? If the commercialization of the label will not solve the problem, we should design their own labels, we can make the antenna electric acoustic simulation, we can see what is your design tag antenna performance. The same sticker is different for different materials, and the performance will be different. We stick the same label on different material, RFID tester can test the performance of a tag, you to label test, test found that do not conform to the requirements, and then modify the design, through repeated several times, you can apply special label design. The product of the label is a variety of products, we can set up the label product database, help various customers choose the most suitable label.

After selecting the label, place the label on the side of the bottle or bottle cap in practice. In this case, there is a plastic bottle in the box, and the red one is weak, and this is the space deployment problem for RFID tags. We chose the label and then how to paste it.

Then solve the problem of reading and writing equipment, we have a series of RFID, speaking, reading and writing, there are a lot of parameters need to be designed, but a lot of system integrators don't know these parameters is what to do. We hung on the door of the RFID reading head, each of us represents a a reading labels, make it as a door, we will have an automatic adjustment of the platform, the help system integrators optimization.

A logistics warehouse door, at the door, I want to fight, speaking, reading and writing on the door in the three antenna or antenna, four each antenna should be hung in any position, many vendors in the process of practical application is four. Seven years ago I made it myself RFID project is also to do this, the left two, two hung on the right, back and forth, doing experiments, if not to take other ways left hanging, hanging on the right side of the two, hang a again above, so that you can pass the test software, tell you this software through a series of development tools, finally tell you the door out of the two goods is enough.

This is where you put two accessor eight antennas and you cover it, or you have a read-reader three wires, and that's the problem of space deployment.

The most important thing about the Internet of things is that middleware, which I am a middleware background, has so far failed to feel a little warm. You do the middleware, the manufacturer offers you development kit, the vast majority of systems integrators have no thought of the problem of middleware, middleware is bad to do so. How do you live now? Flat field oriented middleware, the middleware for the application of the library, I give you a series of component, you need to borrow a book, the first thing to swipe the card, the card is valid card, the second is this book being made an appointment, the third is he have the permission to borrow this book. General RFID application is read card information first, and then to read the information, and then read the card to have this information, through their application to judge could borrow this book. The things you don't do it, I offer a component in the middleware, after he read the card and book information compare, look at this card is able to borrow, give you the result transmission, I middleware business functions are realized. Only this kind of middleware is available now, which is the domain of RFID middleware.

RFID application process modeling and simulation, which we do now. We were in touch with a vendor for the first time, and he said you set up an application, and then we'll go. A partner then we cross the rubicon, because this thing is too important to him, and in his own research and development base in Shanghai, the manufacturers a line complete retrieval, finally all finished, pull the customer to the scene, a customer can have a look at, can do is sign the contract. How big is the risk? Can you do simulations? So we did a simulation software. May originally have bar code to do by hand, the original barcode can do simulation again, and then read the 90% after the application of the RFID technology, read what is going on, a comparison on both sides will have a look at how to improve efficiency, how to reduce the cost, this is the modeling and simulation of the RFID application process.

The customer must ask money, the label of RFID has already been put to 4 hair, the Internet of things can reduce to 4 hair money? We RFID tags to a few cents, maybe next year 2 cents left, maybe 1 cent more than a year, the customer is not without reason, cost is under the RFID industry chain in a concerted effort to reduce.

We have a methodology for doing things. Now have some books teach you how to implement the RFID application, including technical exchange and training, system consulting, application project requirement analysis, and so on all have a set of analysis.

Examples of just now I speak directly to the customer the product line of repetition, the risk is very high, ministry of science and technology in many places now actually throws a lot of money to build the public service platform, RFID public service platform can do? We can put the logistics industry, manufacturing industry and so on all walks of life common problems extracted, such as speed, RFID tags on the bottles after speed write nasty come not nasty, data to read, don't worry if the labels after RFID is fast will also have a question, then extracted the problem of common, in the public service platform to a line, the line like this one line, the line speed is adjustable, the speed can be from 20 meters to 200 meters per minute, per minute in this environment you can use the loop in the environment to do more tests, thereby improve your proposal. RFID tag is definitely can't leave you do waves, waves of this dark room to ten, a company in a build such need money, also need the money, so what can I do? We have built a public service platform in zhangjiang, Shanghai, and the President has built such a platform in shenzhen. The government will build a series of public service platforms throughout the country. Our industry is small, supporting the construction of mainly comes from government funding support, as Shanghai platform a member a year to $2000, with in one hour to want 500 pieces to 1000 pieces. As a platform of our type, you may become a member of our club, join the club for a year and 2000, and continue to do more testing. The money is paid for by the government, the public service platform.

Everyone here try to understand all parts of the country after the RFID iot public service platform, and then use this platform for their own research and development, provide support and assistance for the scheme of test. The platform is simple, like our platform is cheap, it's 2,000 yuan a year.

The third part of the project is the cultivation of professional talents in the Internet of things.

Every enterprise development needs to talents, we also want to catch up with the pace of Internet development, the ministry of education from 2010, 2011, 2010 three years in three batch of examination and approval of close to 150 Internet of things engineering. When you think about what the Internet of things is, the profession has come out, what should the profession teach and learn? We will set up the Internet of the panel, and then wrote two books: "the Internet of things engineering practice teaching system of institutions of higher learning and the specification, the institutions of higher learning in the Internet of things engineering development strategy study and professional norms,". Let's go back and see if we can make a suggestion.

We hope that we will work together to promote the development of the domestic Internet of things and smart cities. Thank you very much.
