Description
Technical field
The present invention relates to a kind of user terminal of REID, specifically a kind of intelligent terminal that utilizes REID to carry out wireless location.
Background technology
Along with the high speed development of mobile computing and embedded system, people are dense day by day to the interest of location aware, so positioning service system also receives increasing concern.GPS is the positioning system that is most widely used at present.Yet in the indoor occasion that waits the user can't keep sighting distance with orbiter, the gps system bearing accuracy is not high, even loses efficacy.In order to improve the precision of indoor positioning, people have adopted technology such as infrared ray location, ultrasound wave location, WLAN (wireless local area network) location, radio-frequency (RF) identification location.Compare with other technologies, REID has noncontact, non line of sight, transmission range is big and the cost performance advantages of higher.
REID is a kind of automatic identification technology that begins to rise the nineties in 20th century, and it utilizes radiofrequency signal to reach the purpose of identification by alternating magnetic field or electromagnetic field couples realization information transmission and the information passing through to transmit.Characteristics such as the RFID label has been realized contactless operation, and it is little to have a volume, and capacity is big, and it is convenient to use, and does not have the machinery wearing and tearing, and the life-span is long, need not visible light source, and penetrability is good, and is reusable, and contamination resistance and permanance are strong.And the RFID label can be worked under rugged surroundings, reads distance, and has used the anticollision technology, can support fast reading and writing, multiple goal identification, mobile identification, non-visual recognition, location and the long-term follow management in real time of a plurality of targets.Since the last century the nineties, the RFID technology has obtained development at full speed.
At present, the RFID technology has obtained using widely at aspects such as logistics and supplies management, the manufacturing and assembling, document tracking, library management, animal identification sign, aviation luggage processing, mail package processing, motion timing, gate inhibition's control and electronic entrance ticket, the automatic charges of road.
In recent years, China has tentatively carried out research and development and the industrialization work of RFID correlation technique, and begins in certain fields to use, but application foundation weakness comparatively speaking lacks core technology, uses and disperses, and does not possess the advantage of scale.
At present, the RFID technology of China also lacks the typical case with great demonstration effect and uses, influenced the popularization of RFID, add that the benefit that the terminal user can bring the RFID technology understands dark inadequately, though make enterprise and mechanism's enthusiasm of research, manufacturing, production RFID label and read write line very high, terminal user such as logistics, manufacturing industry are still being looked around and are being waited for.Along with correlation technique constantly improve and ripe, the RFID industry of China will become an emerging high-tech technical industry group, become the new growth point of national economy.
Wireless technology has entered fields such as communication, industry, medical treatment, consumer applications, logistics transportation and public safety, and its development is closely bound up with the people's daily life.The RFID location is called as " location nova ", and this technology is an important location technology of rising after the GPS location technology.This field is except the mobile phone location technology, the key areas that general public merits attention.The RFID positioning system has self-organization, need not the cooperation of satellite or cell phone network, its degree of accuracy is the distribution of RFID equipment such as read write line, label, and employing wireless radio frequency read write line and label, the user can position in the specific region of oneself arranging according to self actual needs.Therefore, the RFID positioning system is for a user who only needs position in the specific region, as in the supermarket, library, medical department and production management etc. need the occasion locating, monitor and navigate, all have and use great value.
Rfid system is made up of read write line, electronic tag and data management system three parts.
Read write line is that the information in the label is read, or the required canned data of label is write the device of label.Different with technology according to the structure of using, read write line can be to read or read/write device, is the control of rfid system information and processing enter.When rfid system is worked, in a zone, send radio-frequency (RF) energy by read write line and form electromagnetic field, the size in zone depends on emissive power.Label in the read write line overlay area is triggered, and sends the data be stored in wherein, or is stored in wherein data according to the modifying of order of read write line, and can communicate by interface and computer network.
The basic comprising of read write line generally includes: dual-mode antenna sends radiofrequency signal to label, and receives response signal and the label information that label returns; Frequency generator, the frequency of operation of generation system; Phaselocked loop produces required carrier signal; Modulation circuit is sent the signal loading that is sent to label to carrier wave and by radio circuit; Microprocessor, generation will send to the signal of label, and the signal that label is returned is deciphered simultaneously, and the data of decoding gained are returned to application program, if the system of encrypting also needs to be decrypted operation; Storer, storage user program and data; Demodulator circuit, the signal that the demodulation label returns, and give microprocessor processes; Peripheral Interface communicates with computing machine.
According to the power supply form of label, electronic tag is divided into active electronic label and passive electronic label.Active electronic label also is active tag, and battery is housed in the label, uses the energy of battery in the label, and decipherment distance is longer, can reach tens meters even rice up to a hundred, but its price is higher.And because from charged pool, the active label volume is bigger, can't make the form of thin card, also needs to regularly replace battery.Passive electronic label also is passive label, and label does not contain battery, utilizes the energy of electromagnetic field of read write line emission as the energy of oneself.The passive label volume is little, in light weight, cost is low, but transmitting range is restricted, generally has only tens centimetres, and bigger read write line emissive power need be arranged.
The basic comprising of electronic tag generally includes: dual-mode antenna: receive the signal from read write line, and desired data are sent back to read write line; AC/DC circuit: utilize the energy of electromagnetic field of read write line emission, through big electric capacity energy is stored, be output as other circuit through mu balanced circuit again stable power is provided; Demodulator circuit: from the signal that receives, remove carrier wave, demodulate original signal; Logic control circuit: the signal from read write line is deciphered, and postbacked signal according to the requirement of read write line; Storer: as System Operation and the position of depositing recognition data; Modulation circuit: the data that logic control circuit is sent are loaded into antenna and give read write line behind modulation circuit.
The active electronic label that existing RFID technology is used, it is big to exist volume, manufacturing cost height, power consumption height, complex structure, the problem of the multimedia function that do not link.
