Description

A kind of locker adopting NFC recognition technology

Technical field:

The invention belongs to technical field of electric appliances, particularly relate to a kind of locker adopting NFC recognition technology.

Background technology:

NFC technique is developed by non-contact radio-frequency identification (RFID), and jointly developed by Philips Semiconductors (Xian Enzhi Pu semiconductor company), Nokia and Sony, its basis is RFID and interconnection technique.Near-field communication (Near Field Communication, NFC) is a kind of radiotelegraphy of short distance high frequency, runs in 20 cm distance in 13.56MHz frequency.Its transmission speed has 106 Kbit/ seconds, 212 Kbit/ seconds or 424 Kbit/ seconds three kinds.Current near-field communication is by becoming ISO/IEC IS 18092 international standard, ECMA-340 standard and ETSI TS 102 190 standard.NFC adopts initiatively and passive two kinds of read modes.NFC technology is developed by non-contact radio-frequency identification (RFID) and the Technology Integration that interconnects, combining induction card reader, induction type card and point-to-point function on one chip, can carry out identifying and exchanges data with compatible equipment in short distance.But frequency of operation is 13.56MHz. uses the user of this mobile-phone payment scheme must change special mobile phone.This technology is widely used in Japan and Korea S at present.Cellphone subscriber just can go all over the whole nation with the mobile phone being configured with payment function: their mobile phone can be used as gate inhibition's key, traffic all-purpose card, credit card, Payment Card etc. of airport boarding checking, mansion.NFC and bluetooth (Bluetooth) are all short-range communication technology, and are all integrated into mobile phone.But NFC does not need complicated setting program.NFC also can simplify bluetooth and connect.The place that NFC is slightly better than bluetooth is that setting program is shorter, but cannot reach the speed of low-power bluetooth (Bluetooth Low Energy).In two interconnective recognition of devices processes of NFC device, use NFC to substitute and the speed that establishment can be made to connect manually is set greatly accelerates: be less than 1/10th seconds.Largest data transfer amount 424 kbit/s of NFC is much smaller than Bluetooth V2.1 (2.1 Mbit/s).Although NFC less than bluetooth (being less than 20 cm), corresponding can reduce unnecessary interference in transmission speed and distance.This allow NFC be specially adapted to equipment intensive and transmission become difficulty time.Relative to bluetooth, NFC is compatible with existing passive RFID (13.56 MHz ISO/IEC 18000-3) facility.The energy requirement of NFC is lower, similar with bluetooth V4.0 low power consumption protocol.When NFC works on a motorless equipment (mobile phone of a such as shutdown, contactless smart credit card, or smart poster), the energy ezpenditure of NFC is less than low-power consumption bluetooth V4.0.For mobile phone or mobile consumption electronic products, the use of NFC is more convenient.Short haul connection characteristic its advantage just of NFC, because power consumption is low, once only and a machine link, has higher confidentiality and security, avoids stolen when NFC is conducive to credit card trade.The target of NFC is not replace other wireless technologys such as bluetooth, but plays in different occasions, different fields the effect mutually supplemented.

NFC have with low cost, facilitate the features such as easy-to-use and richer intuitive, this allows it seem in some field to have more potentiality---and NFC is by the combination of chip, an antenna and some softwares, can realize the communication of various equipment in a few cm range, and expense is only 2 ~ 3 Euros.Having current research according to the relevant NFC of ABIReasearch, may gain fame and fortune in mobile hand-held device in NFC market.ABI estimates, after 2005, market there will be the smart mobile phone and enhancement mode handheld device that adopt NFC chip.By 2009, this handheld device will account for market over half.Research institution Strategy Analytics predicts, will more than 36,000,000,000 dollars based on the contactless payment volume of mobile phone to the whole world in 2011.If NFC technique can be popularized, it uses the mode of many electronic equipments by changing people to a great extent, even changes the mode using credit card, key and cash.NFC, as a kind of emerging technology, roughly summarizes the disadvantage of Bluetooth technology collaborative work ability.But, its target is not replace other wireless technologys such as bluetooth, Wi-Fi completely, but plays in different occasions, different fields the effect mutually supplemented.Because the message transmission rate of NFC is lower, be only 212Kbps, be not suitable for the application that such as audio/video flow etc. needs higher bandwidth.For the development of NFC, have address prediction, the sales volume of global NFC mobile phone in 2013 will increase by 156%, and total amount will reach 400,000,000, and this just means, the smart mobile phone in the whole world 1/3rd all will support NFC function.Prediction is prediction, and reality still will be faced the reality, and domestic NFC application is still little, with regard to Pekinese NFC payment provider uses, the industry insiders say, can describe with gloomy." the NFC project of China Mobile is terminate with news conference.", " the NFC project of China Mobile is more ostentatious project ".Deng Xin also thinks, NFC can be divided into three developing stage, sample, product and commodity stage, and domestic NFC development remains sample stage, and ordinary populace considerably less use NFC pays.

" locker " is exactly allow user can realize self-service stored article, is also automatic locker, a kind of title of Automatic Depositing Bag cabinet.Originate in Japan, afterwards in Taiwan widespread use.Within 1999, start starting in China's Mainland to occur and progressively widespread use.Mainly be divided into mechanical type and the large series of computer-shape two at present.Locker is mainly divided into following a few class.Coin-feed machine automatization locker: mainly contain and be divided into charge type and free type 2 class, current usable range has: supermarket, library, bathing beach etc.Coin-charging type locker: for station, harbour, whip-round tourist attractions, public arena etc.These places generally use 34 lattice or 36 lattice.Along with the continuous demand in market, also there is change in coin cabinet, and not only for depositing small article, coin locker is also used in various place.Bar code multifunction electronic locker established by machine: for public arenas such as supermarket, sales field, Xinhua Bookstores.The long-acting locker of point-and-shoot non-contact card: for community letter report management, employee's locker, lease cabinet etc.Also for there being the public arena of personnel's post, as: Internet bar, hotel, bathing pool.Once effectively sweep card access locker: utilize employee job card scan access, utilize student card scan access, utilize member card scan access.Special-shaped card, key-type card locker: change one's clothes for bathing, Saunas is changed one's clothes, employee changes one's clothes.Central control system NFC cabinet: carry out switch gate by gathering user NFC, this NFC system specific aim is stronger and security is higher, and the scope of application is wide, and school, supermarket, institutional settings office etc. all can use.Can be arranged to that popular pattern is namely random to be used, or fixed mode and special messenger special.
