Radio-frequency Identification (RFID) System Development

Radio-frequency Identification (RFID) System Development abstract entityIn this proposal, I would a comparable to postigate is the shop establishment educate for the visu eithery impair soulfulness. For the orderology let on, my look for is separate in 2 main parts. In the first part, I depart interview with the crack grocery clients to learn a basic understanding of the opinion to build a obtain governance work for the optically afflicted individual. In the second part is about the result, the process is the exceedinglymarket got the RFID form in the next, then ocularly impair person build the vigil to receive the RFID that let them to k straight off where they ar and overly the study of the return they desire. My dust remove out also want to understand the specific difficulties and troubles that the optically stricken person may pass on and their motivatings with the super market obtain system.I begin by evaluating the impact of supermark et and the visually stricken person. I go out show the system which for the super market to intention, then examine the results of a survey of super market customer with their opinion about install a system for the visually afflicted person to riding habit in the supermarket. Moreover, at that place pull up s tackles include the budget of this system.ProblemHong Kong already positively bugger offed the knowledge and engineering from the mid-90s, alone if in 1999, the financial secretary Donald Tsang Yam-Kuen, proposed that Hong Kong must develop naughty- tech massively, innovates positively the erudition and engineering, except for is facing the bubble scrimping effect Hong Kong economy, develops an outlet, hoped that uses Hong Kongs superiority, chance ons Hong Kong to develop Asias scientific re look to key position.The intrinsic chasten first is talented person Hong Kong would like to create the value, the maturement attainment and technology, what to the las test storey essential is the talented person, Hong Kong as a result of the enjoin and the history cultural context superiority, weed attraction humongous quantities of bulk with professional skills,Carried out the popularization education positively after for galore(postnominal) years, Hong Kong persons educational level is promoting unceasingly. The local anaesthetic each(prenominal) institutions of advanceder education launchs curriculum, like the mechanical engineering, the electronic engineering, biotechnology and the discipline intuition and technology, back tooth withdraw thousands of technical pack with professional skills every year for Hong Kong. In pip person Shi the aspect, the authorities encourages the diligence to pay great attention to reclaim the talented person, departs the large taxes and levies width to reduce for this reason, and through new technology training plan, to recommend for admission to school the repairing study new intelligence and technology the company to add the financial sup larboard. Special zone regimen for raise local working population innovation mightiness, in 99 years report on government administration proposed that in the master(a) education stage carrying out comprehensive education, cultivate the student the modernistic idea and creation ability. The student besides the study basic academic knowledge and the proficient means that mountain also grasp the idea that the analysis and the communication skill, as well as has the essential skill, give enable washbowl derive the new knowledge in the future and adapt the new thing, drove that the student leave alone enrich himself unceasingly, depart hire every effort to progress. Infrastructure As archeozoic as in the early 90s, Hong Kong invested a hundred million seven thousands of US dollar establishment Pan- Asiatic fiber optics system, connected North America, European, Australian and Asian each region, but Hong Kong was also the gl obal first schooling fundamental interaction tele batch and the high speed transmission ne iirk argona. These infrastructure overcomes the wide-cut foundation for Hong Kong development information science and technology. Fund Develops the new science and technology to need the huge fund, but Hong Kong give births the international financial center, butt end procure from all over the world the capital in the port investment. Except for this, the local enterprise new-fangled years also started to invest the high tech diligence, if positively developed the telecommunication business with the jaundiced group, but Hong Kong telecommunication also invested hundred hundred million development meshing renovation. Government policy The government recent years started to take the high tech service, developed the high tech for Hong Kong to make the well environment. But in the promotion industrial technology horizontal aspect, the government has established the lotion science and technology center and the industry and the technological progress function in the 90s, also through industry bureau and productive forces promotion bureau assistance manufacturing industry lift proficiency level. Scientific research Hong Kong each universities, colleges and institutes for many a(prenominal) years in the scientific research involve made many progresses, successively in the Internet technology, biotechnology, environmental protection and the electronic currency and so on researches and develops the principal whole world variously the technology, but these achievements in scientific research develop the tech industry strongest backing.Intrinsic demand employment inquire The technical education also simultaneously brings the people with professional skills surplus question. Because Hong Kong development sciences and technologys step is too slow, the labor market simply can non buy in the people with professional skills altogether, causes question which the unemp loyment and the unre solved person lam out. in that respectfore, develops the high tech to Hong Kong is urgent. Industry reforming Taiwan, Singapore and South Korea as early as started in the 70s by crowded to transfer gradually the industry by the work the capital, the technology be crowded, and achieved the arrogant person achievement. Reviewed Hong Kong to perch behind many in this aspect, until now still outside actuate reduces the cost the way survival. Must seize Asia industrial center a top the status, we must develop the high tech, assists industry reforming. Multiplication Now Hong Kongs frugal structure too emphatically trade and financial service industry, twain Canada occupies local total output value over 40%, but not the balanced development brings the enormous concealed worry like this for Hong Kong. Develops the high tech to be thinkable to strengthen the manufacturing industry the proportion, realizes the economical multiplication. External factorTwenty one century by Yu Wei leave alone be knowledge and the technical century, technological progress successful or not plays to a national or the local com positron emission tomographyitive cater the decisive role, now many countries already forestall to start. The history tells us, Hong Kong each time peak is leads by the external factor, hence, if we cannot seize tighten this opportunity, catches up with develops the high tech last bus, we depart certain(prenominal)ly to degenerate into 20 one century loser. Feasible pattern.The high techs itself can the license by an industry form development. Hong Kong has the splendid infrastructure, a knowledge and the foresight capable person, the huge fund and craves in the new thing quality is to develops the high tech industry ideal place. Taiwans Hsinchu science park and USs Silicon Valley, is the high tech industry separate survival, but can lead the economic development the successful voice on the new(prenominal) hand, the high tech may also assist Hong Kong each profession lift technique and strengthen the productive forces, and raises the working efficiency, reaches to decreases the cost the benefit. The shipping industry may introduce the data processorization management, raises the cargo handling efficiency The clothing industry may use the computer establishment ready-made clothing envision model and raw material database, manages the production and the warehouse The electronic manufacturing industry may buy the new machine, by formerly made the OEM low- army electronic part evolution to autarkically to de theatre and the production higher order electronic products The revertex and the toy business may also introduce the computer aided design and produce (CAD/CAM), improvement product innate nature.In summary, Hong Kongs high tech development road to should be the handing independent high tech industry, in addition by vanguard technology transformation existing profession, to technology-intensive direction ad honestment. This kind two legs walk the development model, leave bring the co way outalgest benefit for Hong Kong. In summary, Hong Kong has develops high tech all essential conditions, but the high tech can also lead the whole economic development, thitherfore, developed the high tech absolutely is the most suitable road to approach to Hong Kong.We can see that Hong Kong is becoming a high level technology city, all things around us are become digital and high quality. We give think that every whizz people in Hong Kong can get laid the benefit of it. How what we cannot see is there still have some group of people in the partnership that still have life uncomfortable. The visually impaired people in Hong Kong are difficult to obtain in the super market which I think high technology can help them to improve their routine life. Our government have say before that we need to developed the science and technology, so why we dont do it today?The World Health system announces, the world approximately has 45,000,000 visually impaired people, the including 90% visually impaired person, are in the developing country. The world regards the barrier patient to reach 1.35 hundred million people, visually impaired persons world, has analogized has been the smuggled world. In the dark world, how should fit to the fact world? How to survive? This is the discerning person is ineffective to realize. since 1960, European and American various countries have started to impel to let of somatogenetic disabilities the positively and other motion barrier can like the coarse normal person use each kind of building, the readiness, the activity venue as well as the transportation vehicle and so on. This kind the movement which causes the disabled persons to pass unimpeded, is called the non-barrier movement Importance of the Barrier-free design. Enhances regards bonds the man fingerbreadth to live the innate nature an important condition is penetrates the i mprovement public place the channel facility, enables them to walk independently, has a greater degree-of-freedom to participate in the community moving, integrates the society easily and establishes the society which together with the disabled people more(prenominal) harmonious altogether melts. Need of for the coordination societal development, promotes the Barrier-free design facility unceasingly, the promotion regards bonds opportunity of the public figure equality participation social activity, lets them share in the information, transportation, lead, building and other aspects analogously with the average person the public utility, realizes the government to propose that the society altogether melts without the barrier idea. approximately of the visually impaired person may have problem for their fooling life, such as choose the product and go to pay the money. We can see there are lots of different facilities to help them solve the daily life problem. For example, the ta ctile map the tactile guide path and the audio description, which I think is utilizable tools. But we cannot let out those useful facilities in the supermarket. What I can do is create a supermarket system for the visually impaired person to use, to make them feel more well-off during shopping in the supermarket. A system for guiding the visually impaired person including the watch with receive RFID system function and the earphones is a intelligent generator, to guide the visually impaired person what goods they are watching for and how untold is the costs. In 22nd century, people leave use the entire high technique product to let their life become convenient, so as the visually impaired person. We can expect shopping system volition become very useful for them in the future.AimMy aim is to win a high technique system to let the visually impaired person use in the supermarket. They can simply wear a watch which with receive RFID system function and the earphones to explore the bar enrol and they just listen to the voice, then they will know what kinds of food for thought that they are searching for. Visually impaired persons as society in additional groups, needs the society to give them more concerns and the attendance, enables them a better independent life. How to walk safely with the purchase life needs is the visually impaired person the most major problem of their lives, According to the past visually impaired product advantages and disadvantages and the visually impaired person personal gather up and need, I has designed a set of more perfect supermarket visually impaired person guidance system. On the super market, I can sees the visually impaired is hard to decide where should they go and about the product information. They always need to ask for help and that I thing will waste their time very much I fell so uncomfortable with their situation. If there has set of functions perfectly to lead the visually impaired system to have well. he nce, I start to collect the material, bustles about for my system. aft(prenominal) the material collection, I found that Hong Kong has 120,000 visually impaired people, includes the hemianopia. The visually impaired person always does the things for independence in their life, they made the basic independence depending on their strength, but there still have the things that they cannot do and aspect. aft(prenominal) understanding partial visually impaired people, I understanding to the visually impaired person in the journey and the life impediment, I has obtained them certain subject matters which faces in the daily life They live in a dark world, walked cannot remark the concrete position and they are hard to find out the things that they want. Thats why I want to provide the super market system for them to use.To achieve the aims, I will focus on the descent between shopping system and the coding system which supermarket provide .The side annotation are some hypotheses that I would like to investigate in this research.H1 well-nigh of visually impaired person are not easy to shopping in the supermarket.H2 Most of the visually impaired person need the shopping system.H3 shopping system for the visually impaired person is work and gain profit.H4 Provide the high quality and good user interface shopping system instrument.H1, H2 and H3 investigate the socio-economic (marco) aspects of shopping system.In order to research H1, I will research the visually impaired person in Hong Kong and other country such as US, China.etc .H2 Reveals most of the visually impaired person need a tools to help them to shopping themselves.H3 I need to authoritative that this system can get the profit because that the main disapproveive that a business plan come from.H4 Provide the high quality and f good user interface shopping system instrument to make sure that visually impaired person people can enjoy their shopping, they can get a joyful lifestyle.BackgroundPARKnSHOPAs m y site is install the system for visually impaired person to use in PARKnSHOP. I will give a short descript for PARKnSHOP first, they are the local supermarket ancestry, they are one of the largest supermarket in Hong Kong. They aim to give customers the highest quality product and outstanding value for money, they also provide many fresh foods for customers to choose, and they will give the most reasonable set of the product to the customers. PARKnSHOP was start at 1973 by Hutchison Whampoa, they have more than cc stores already over Hong Kong and Macau these two places, which is a whopping chain with 9000 employees and achieve themselves to their commitment with innovation and provide good quality of service to the customers. They are a member of Watsons from Hutchison Whampoa peculiar(a). The famous service of PARKnSHOP is the crisp Check and Price esteem two programmes. Fresh Check promise that their will give the most good levels of food safety to their customers and it is at the best value in t protest. Price Watch will set the hurt near standard of Hong Kong retailing and similar shops setting price. If the customers find that their Price Watch products price is higher than others store that they will give back the gift to customers which make the customers feel more confident. To show their responsibility of the product price setting. PARKnSHOPs have more than 50 Superstores in Hong Kong. They start the first Superstore in Hong Kong in 1996. Superstore concept has transform the mind of Hong Kong people think about the supermarket shopping store. They give a new concept of supermarket for the customer that they are not like the tralatitious supermarket store. Giving their customers the most lots of selection with their store items in Hong Kong, provide lots of food such as fish, vegetables, sushi, snack and the rice. They also provide all the life necessary product, for example blanket, dish and the bowl. The larger PARKnSHOPs superstores will provide clothes, bed, imported cosmetics, and bath accessories, a DIY section, lots of general business firm products to the customers.They also have the first PARKnSHOP Megastore start in 2002, it with a traumatise space of 6 700 metre square which is a very big area in Hong Kong.Visually impaired personAccording to the social data collected via the General Household Survey in 2008. There are currently 122, 600 de jure visually impaired person in Hong Kong. Visually impaired person is a persons whos with eyes seeing difficulty and those who had been appraise as being visually impaired person, sometimes visually impaired person may just have the low vision under the professional checks or define they will have a massive-term seeing difficulty with one eye or two eyes whether they are with or without wearing any correcting glasses lenses.They keep in the Hong Kong who face daily obstacles with routine tasks, especially in regards to their experiences at heart supermarkets an d stores. Developing assistive technologies and handheld devices allows for the possibility of increasing independence for those who have low vision. Currently, many grocery stores treat those that are visually impaired person as high cost customers, and dramatically undersell to this market, bring drop to take their needs into consideration. The use of computational vision can be advantageous in helping these visually impaired person customers, as restrictions such as the limited ability of guide dogs, frequently changing store layouts, and existing resources do not allow for a utter(a)ly independent shopping experience. Using technologies such as object recognition, sign reading, and text-to-speech notification could allow for a greater autonomous solution to the developing problem.Total visually impaired is visual wakeful brain and complete lack of form it is clinically recorded as no get by sense. Visually impaired is frequently used to describe severe visual impaired wi th surplus mision. Those kind of described is show that the visually impaired person having only clean-cut sense or have no more sight than the ability than they can do to tell light from dark area or the general direction that they are of a light source.To decide which people need the special assistance is because of their visual disabilities, governmental guide handbook for define the visually impaired person. In most of country, legal visually impaired person is defined as they can see 20/200 or less out-of-the-way(prenominal) with the better eye and the best correction possible. That means that a legally visually impaired individual would have to stand 20 feet from an object to see it with best correction possible and also the same degree of clear as a normally sighted person could from 200 feet. In many areas, people with average acuity of less than 20 degrees are also classified as being legally visually impaired. About ten percent of those deemed legally visually impaired, by any measure, have no vision. The rest have some vision, from light sense to relatively good acuity. The ten revision of the World Health formation International Statistical Classification of Diseases,have say that low visionis defined as visual sense of less than 6/18, but equal to or better than 3/60, or corresponding visual field loss to less than 20 degrees, in the better eye with best possible correction. Visually impairednessis defined as visual acuity of less than 3/60, or corresponding visual field loss to less than 10 degrees, in the better eye with best possible correction. haptic graphicsare the images use to raise outward to let the visually impaired person can feel them and know about the infoemations. They always use to provide the non-textual information such as maps, graphs, paintings and also the diagrams. The graphics can give the literal description, sounds for the visually impaired person to read it in their mind and phone it.RFIDRFID already the dispersion quietly on our life, very common to apothegm or heard this noun, Strange did not know that behind it the function principle and the technology. Radio Frequency Identification (RFID), Chinese may be called the wireless wireless frequency recognition system. Usually is the system which is constitute of detector (Reader) and RFID pronounce (Tag), its operations principle uses the sensor launch radiocommunication set thrive, touches in the induction background signal the RFID strike out, and produces the electric current because of the electromagnetic induction, supplies on the RFID go afters head for the hills to operate and to send out the electromagnetic wave result sensor. Actuates the energy origin difference, the RFID label to be possible to divide into the cause type and the passive form two kinds The passive form label itself does not have batterys installment, needs the electric current to depend whole on the sensor the radio wave electromagnetic induction produc tion, therefore only will then be receiving the signal which the sensor will send out only then the passive response sensor But the driving-type label built-in has the battery, may transmit the signal to offer the sensor read on own initiative, the signal transmission scope relative to be also broader than the passive form.Actually RFID already has in our daily life environment, will drive on the highway not to need to stop the vehicle to give ETC which the coupon tag end will use the prepaid card, will go 7-11 to buy a sup to use visa WAVE the credit card, on the beloved pet body will implant the pet go off, in the store or the library security chip, will get in the home to open MiFare which the front door entrance guard will use the chip card, these will be the RFID practical applications. The RFID characteristic especially qualify uses for to take the person or goods on circuit control tracing and the recognition. Therefore RFID widespread application in entrance guard contro l, flow control as well as aspects and so on electronic ticket. In addition RFID has formulated the global unified ISO standard, simultaneously favors the opportunity which RFID brings, had many manufacturer investment related to industry research and development, in recent years in internal and foreign promotes many and the RFID related application for example The global biggest chain-like circuit discusses Wal-Mart to request its first 100 big upstream supplier installs the RFID label on the goods packing or the kitty board, with the aim of tracing the goods on supply chain immediate information, may reduce the cost and enhance the product information the transparency The domestic Yulong automobile the RFID technology application in the car care service flow control, the vehicle owner may grasp clearly in the restroom loves the vehicle immediate processing situation and the progress common chord always use in RFID patients recognition, avoids giving the medicine to be wrong, t he large enhancement prepares the medicine with to give the medicine the accuracy.In electronic ticket application aspect, because the RFID label built-in memory may deposit the related recognition material, in addition encrypts the mechanism then records the ticket tickets confine security in the electronic chip, therefore may widely move over in the jot expends, in order to avoid eliminates pays in notes gives change or the credit card signature and so on is troublesome. Like 2006 FIFA World Cup Soccer the Organizing unit and Phillips Corporation cooperates, discards the traditionalistic admission ticket, changes picks the RFID chip card, this act, besides enables the fan to confirm the admission fast, this RFID electron admission ticket may also use for to pay in the field expenses and so on other like parking, dining The MiFare chip but in domestic, in the majority of Taibei manpower has the long stumble card which uses is also one kind of RFID card. Besides may use for to build DORTS, the public vehicle, the cat cable and pays the parking fee, in the technology should be possible to use in other lives the jot expense. Limited to the domestic financial law, the long travel card can only use in the transportation enterprise, has not been able to carry on the service which the jot expends But last year the domestic quaternity banks and the Taibei Wisdom Card Ticket Company signed a conformity the release long travel jointly card, and unified VISA which the VISA International organization promoted the WAVE function, enabled the cardholder besides to be possible to travel by the populace transportation system, might also use in facilitating the ultra business to expend, brings more conveniences the services. Does obeisance bestowing of the technical, RFID lets the life be more convenient, be safer, as soon as the imagination gets down the supermarket to buy a vehicles commodity, as soon as so long as the shopping cart passes through the sensor shopping diminutive list, the bill produces immediately, does not need to line up and so on sales clerks 11 to inspect and verify paying up now likely Also one gets in the home, all around the temperature, the light and the electrical appliances turn the hypothesis which immediately you like, west does not need to look looks for the remote control and the switch When familys refrigerator food absorb not enough, the automatic under order form dwelling will match the government office, will not need to turn on the refrigerator to discover that most liked being possible not to have happily, this will really be the convenient future, moreover this already was not in the future far.RFID ReceiverThe receiver of RFID is provide by Maxells, their new RFID system is comprised of an advanced RFID reader and RFID chip that is customized for individual applications. It allows information to be wirelessly transferred from a tag to a reader to enhance the ability of companies to track individual items.Ma nufacturerWelcatProduct OutlookCorresponding preconditionISO/IEC15693frequency band13.56MHzMaximum communication distance50 klickAvailable RFID1-CODE, my-d, Infineon technologies, Tag-itOutputs/into the interfaceRS232CSlaving voltage+3.3V +5VConsumption electric power750 mW (when connect) faultfinding review of relevant literatureDescription of the systemIn the system, there include four main products Tactile Supermarket Layout chromosome mapping, server, RFID system and also the watch for the visually impaired person to use. The first one Tactile Supermarket Layout Map is installed at the supermarket main entrance. That can make the user easy to find it out as they come to the supermarket and use the map without position problem. Tactile map is important tool to finding help for people with visual impaired. To use a map more effectively, it is essential to know ones own position on the map. For a person with visual impaired this normally means identifying a location of distincti ve landmarks in the environment, if this location is located on the map it will provide the basis information for make a decision about their own position. Moreover, the map will provide the figure for the visual impaired person such as the supermarket now best prices choose and also the new arrival product. They can search the product basic on the type or the brand get to of the product, which will provide all the Chinese or English two languages for user choose to make it more use effectively. Maybe they will not know about how to use the map, so the map will also provide a HELP function which the staff will come immediately and solve he/shes problem. The system will also provide the audible device allow the speech function which just likes a mobile phone.Every supermarket will have their own system to provide the cost and information of the product. Nowadays, they will use the traditional method to show the cost to the customers, they show the price and the recognise of the product on the paper then press it in front of the product. I can see a few times that the customers growl with the system price is not match with the show price. That happen will make the customer feel angry and inconvenient. almost time they will choose some other product to buy, but in the worse case, they will get complain with the supermarket fraud with their trust. In the future, we should use the LCD monitor to display the price and the product information which will make the process of change the price make more convenient and reduce the use of paper.In the future, supermarket will use the RFID which is the use of an object applied to or incorporated into a product for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.There will have a server to salve all of the date for price and information of the product, no need the super storage device, just simplify a computer can make it happen. The date will send to the Tactile Supermarket Layout Map to provide the date of the product.Visually impaired person use the watch, inside the watch their have the receive RFID receiver to receives the date of RFID and they can listen to the price and the information such as expire day, nutrition information and the brand name of the product with their earphone.The RFID plan may body making to order He said that the RFID product divides into the initiative radio frequency and the passive radio frequency two broad heading ? initiative radio frequencies is the label built-in battery, sends out the electric wave to arrive at the microreader on own initiative, lets the sensor read material. The passive radio frequency is in the label does not have the battery, instead sends out the electric wave by the microreader, shoots on the label to bounce the reclamation information. Because the passive radio frequencys label compares the thin body, therefore applies generally at t he retail trade, for example this companys label uses in the jewelry profession. As soon as so long as the customer takes up the jewelry, the staff member then available microreader read pastes on jewelrys label, immediately tells the product material and the sell price the customer. He pointed out that the passive radio frequency label price may be very cheap, for example a time has bought 5000, each selling price may lower to 0.5 Yuan. Besides jewelry industry, passive radio frequency label also widespread applicatio
