Abstract
The invention discloses an RFID-based supermarket shopping guiding method. Corresponding electronic tags are arranged in positions of all kinds of commodities of a supermarket, a plurality of RFID card reading devices area are evenly arranged in the supermarket, each RFID card reading device is controlled to read information in the electronic tags in all kinds of commodities in a preset reading range of the RFID card reading device, and an index list is established for the information that is read; after a customer inputs commodity information to be inquired on a handheld device, a query request of the commodity information is sent to the RFID card reading device closest to the customer; and the RFID card reading device returns a result after a query, and the handheld device guides the customer according to the return result. The RFID-based supermarket shopping guiding method is simple in design and convenient to use, and can rapidly find the place where the commodity required by the customer is and guide the customer to go.
Description
Technical field
The present invention relates to RFID application, particularly relate to a kind of supermarket shopping bootstrap technique based on RFID.
Background technology
RFID is the abbreviation of RadioFrequencyIdentification, i.e. radio-frequency (RF) identification, and be a kind of contactless automatic identification technology, it identifies destination object automatically by radiofrequency signal, can carry out item tracing and exchanges data rapidly.Identification work need not manual intervention, can work in various rugged surroundings.RFID technique identifiable design high-speed moving object also can identify multiple label simultaneously, swift and convenient to operate.RFID technique is born in World War II, and it is the successor of traditional bar code technology, is also called " electronic tag ".
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 has following Performance Characteristics:
1. rapid scanning, RFID identifier identification simultaneously can read several RFID label tag.2. volume miniaturization, various shapes, RFID does not limit by size and shape in reading, not to be required to be reading degree of accuracy and to have coordinated fixed measure and the press quality of paper.In addition, RFID label tag more can toward miniaturization and various Form Development, to be applied to different product.3. contamination resistance and permanance, the carrier of conventional barcode is paper, is therefore easily polluted, but RFID has very strong repellence to materials such as water, oil and chemicalss.In addition, because bar code invests on polybag or outer packing box, so especially easily lost; RFID label deposits in the chips by data, therefore can from stained.4. reusable, just cannot change after bar code printing now gets on, RFID label tag then can repeatedly increase newly, revise, delete the interior data stored of RFID label, facilitate the renewal of information.5. penetrability and without barrier read, when capped, RFID can penetrate nonmetal or nontransparent materials such as paper, timber and plastics, and can carry out penetrability communication.And bar code scanner when closely and when not having object to stop, just must can distinguish wanding.6. the memory capacity of data is large, the capacity of one-dimensional bar code is 50Bytes, the maximum capacity of two-dimensional bar can store 2 to 3000 characters, and the maximum capacity of RFID then has several MegaBytes. along with the development of memory carrier, and data capacity also has the trend constantly expanded.The data quantity carried needed for following article can be increasing, can expand the demand also corresponding increase of capacity to label.7. security, due to RFID carrying is electronic type information, and its data content can, via cryptoguard, make its content not easily be forged and alter.RFID gets most of the attention because of its characteristic such as remote reading, high storage capacity possessed.It not only can help an enterprise significantly to improve the efficiency of goods, information management, can also allow sale enterprise and manufacturing enterprise interconnected, thus receiving feedback information more exactly, demand for control information, optimizes whole supply chain.
Existing supermarket generally adopts Sign Board to carry out direct customers and does shopping, but, because Sign Board is dispersed in each place in supermarket, if client is unfamiliar with supermarket, just whole supermarket must be run one time, just can know the place place of each commodity, in view of the life of present fast pace, people go to supermarket shopping with tendency of significantly doing shopping, and it is desirable to directly to know article location, supermarket.
Summary of the invention
Technical matters to be solved by this invention is for defect involved in background technology, provides a kind of supermarket shopping bootstrap technique based on RFID.
The present invention is for solving the problems of the technologies described above by the following technical solutions:
Based on the supermarket shopping bootstrap technique of RFID, comprise following steps:
Step 1), in supermarket, all kinds of commodity place arranges the electronic tag corresponding with it, with the details of storing commodity;
Step 2), some RFID reader devices are evenly set in supermarket;
Step 3), controls each RFID reader device and reads information in its default read range in all kinds of commodity electronic labeling;
Step 4), for each RFID reader device, sets up index to the information that it reads;
Step 5), client holds handheld device and enters supermarket;
Step 6), after client inputs the merchandise news that will inquire about on a handheld device, the RFID reader device that the inquiry request of this merchandise news sends to distance client nearest by handheld device;
Step 7), after RFID reader device receives the inquiry request of merchandise news, inquire about in its index, return Query Result, the inquiry request of this merchandise news is transmitted to adjacent RFID reader device, until all RFID reader devices all complete the inquiry for these commodity simultaneously;
Step 8), handheld device receives Query Result, judges the coordinate that whether there are inquiry commodity in Query Result;
Step 8.1), if there is no inquire about the coordinate of commodity, show without these commodity on a handheld device;
