Description
Technical field
The present invention relates to tube advertising field, particularly relate to a kind of underground tunnel advertisement Play System based on RFID.
Background technology
Radio-frequency (RF) tag is the physical support of product electronic code (EPC), is attached on traceable article, can circulation worldwide identify it and read and write.RFID(RadioFrequencyIdentification) technology receives the concern of people in recent years as the gordian technique building " Internet of Things ".RFID technique early originates from Britain, and be applied in World War II and distinguish enemy and we's aircraft identity, the sixties in 20th century starts commercialization.RFID technique is a kind of automatic identification technology, and after U.S. Department of Defense specifies on January in 2005 1, all military materials all will use RFID label tag; FDA Food and Drug Administration (FDA) advises that pharmaceutical manufacturer utilized RFID to follow the tracks of normal medicine of faking from 2006.A series of action such as Walmart, Metro retail trade applying RFID technology have promoted RFID especially in global application upsurge.When 2000, the price of each RFID label tag is 1 dollar.Many researchers think that RFID label tag is very expensive, and only reducing costs could large-scale application.When 2005, the price of each RFID label tag is about 12 cents, and the price of present ultrahigh frequency RFID is about 10 cents.Can RFID wants large-scale application, is to reduce RFID label tag price on the one hand, bring value-added service after will seeing applying RFID on the other hand.The statistics of statistics office of European Union shows, 2010, there was company's applying RFID technology of 3% in European Union, and application distribution is in identity document and access control, supply chain and inventory tracking, vehicle toll collection, antitheft, production control, asset management.
The basic functional principle of RFID technique is also uncomplicated: after label enters magnetic field, receive the radiofrequency signal that plug-in reader sends, the energy obtained by means of induction current sends out storage product information in the chips (passive label or passive label), or the signal (ActiveTag of a certain frequency is initiatively sent by label, active label or active tag), plug-in reader reads information and after decoding, delivers to CIS and carry out relevant data process.
The rfid system of complete set, be made up of reader and electronic tag i.e. so-called transponder and application software system three part, its principle of work is the radio wave energy that Reader launches a characteristic frequency, send in order to the data of driving circuit by inside, now Reader just received in sequence unscrambling data, gives application program and does corresponding process.
Can be divided into haply with the communication between rfid card sheet reader and electronic tag and energy-sensitive mode: inductively and back scattering be coupled two kinds.The RFID of general low frequency mostly adopts the first formula, and higher-frequency adopts the second way mostly.
Reader is different with technology according to the structure used can be read or read/write device, is that rfid system information controls and processing enter.Reader is made up of coupling module, transceiver module, control module and interface unit usually.Between reader and transponder, the general half-duplex operation mode that adopts carries out message exchange, and reader provides energy and sequential by coupling to passive balise simultaneously.In actual applications, the management functions such as collection to object identification information, process and teletransmission can be realized further by Ethernet or WLAN etc.Transponder is the information carrier of rfid system, and transponder forms parasitic element by coupling element (coil, microstrip antenna etc.) and microchip mostly.
RFID is one and is easy to manipulation, simple and practical and be particularly suitable for the dirigibility application technology of Automated condtrol.Under can being freely operated in various rugged surroundings: short-range radio frequency product is not afraid of the rugged environment such as oil stain, contamination by dust, bar code can be substituted, such as, on the streamline being used in factory tracking object; Long distance radio frequency products is used in traffic, and decipherment distance can reach tens meters, as automatic charging or identification testing vehicle register etc.Radio-frequency recognition system mainly contains the following aspects system advantage: read convenient and swift: the reading of data, without the need to light source, even can be carried out through external packing.Effective decipherment distance is larger, and when adopting the active tag from charged pool, effective decipherment distance can reach more than 30 meters; Recognition speed is fast: label one enters magnetic field, and plug-in reader just can read information wherein immediately, and can process multiple label simultaneously, realizes batch identification; Data capacity is large: the two-dimensional bar (PDF417) that data capacity is maximum, at most also can only store 2725 numerals; If comprise letter, memory space then can be less; RFID label tag then can according to user need extend to several 10K; Long service life, applied range: its radio communication system, make it can be applied to dust, the contour contaminated environment of greasy dirt and radioactive environment, and its closed packaging makes its life-span substantially exceed the bar code of printing; Label data dynamic is changed: utilize programmable device can write data to label, thus gives the function of RFID label tag interactive portable data file, and to compare type slug shape code less the write time; Better security: not only can embed or be attached on the product of difformity, type, and cryptoguard can be set for the read-write of label data, thus there is higher security; Dynamic realtime communicate: label to communicate with plug-in reader with the frequency of 50 ~ 100 times per second, as long as so the object accompanying by RFID label tag appears in effective identification range of plug-in reader, just can follow the trail of dynamically its position and monitor.
Advertisement in subway tunnel is arranged on the visible angle of every individual advertisement picture of width in tunnel wall by restriction, when train high-speed motion, make to be arranged on picture in tunnel wall with the relatively-stationary position of passenger on flash fast one by one, thus make passenger experience animation effect.
Existing underground tunnel advertisement is generally come by continuous print static billboards, during each replacing advertisement, all need for a large amount of placard of play advertising and printing, then personnel's one_to_one corresponding of arranging work is puted up, and at placard behind with LED illumination, waste time and energy, and the placard changed is generally just discarded, can not reuse, very not environmentally.
