Technical field
The utility model relates to a kind of radio electronic label that is applicable to intelligent transportation.
Background technology
RFID radio-frequency (RF) identification (Radio Frequency Identification) is to start to rise a kind of automatic identification technology also moving to maturity gradually the nineties in 20th century.REID utilizes radiofrequency signal to realize contactless information transmission by Space Coupling, and passes through transmitted information and reach identifying purpose.Concrete, radio-frequency (RF) identification is mainly by card reader (or being called reader) be attached to the mutual information transmission between the electronic tag (or being called radio-frequency identification card) being identified on object, read the information of carrying on electronic tag by card reader, and undertaken alternately by Internet Transmission and background data base, realize the function such as identification and inquiry to information.Compared with now widely used automatic identification technology such as bar code, magnetic card etc., REID has advantages of a lot of outstanding: Touchless manipulation, and long distance identification (can reach several centimetres to tens meters), need not manual intervention, and application is convenient; Machinery-free wearing and tearing, the life-span is long, can work in rugged surroundings; RFID passive label low price, is beneficial to universal.Constantly perfect along with radio frequency automatic identification standard, RFID starts extensively to start in fields such as material tracking, supply chain management, communications and transportation and access controls application, and market outlook are wide.
Along with the development of microelectric technique, slim small and exquisite electronic label chip, not only can store enough data, and has the ability of carrying out information interaction with reader, has obtained significant progress in the application of commodity identification and field of anti-counterfeit technology.Electronic tag is for commodity identification and anti-counterfeiting technology, that merchandise news and false proof data are stored in electronic tag, in the commodity process of circulation, the data in reader reading electronic labels, by with server in the data of database identify and compare, realize the Antiforge inquiry of commodity.Along with the development of telling of society, the demand of product is increased, market competition is also day by day fierce, enterprise's an urgent demand continues to improve the reaction capacity to market, improve the competitive power of enterprise, because RFID technology has the advantages such as noncontact, input speed is fast, accuracy rate is high, reliability is strong, break through " bottleneck " problem of traditional data collection typing.But existing radio electronic label is not encrypted processing to equipment itself, electronic labeling information is easy to leak, also be easy to other read-write equipments to cause interference, use complexity, be not suitable for the place that the demands such as sales field are large and floating population is many.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide one label information can be sent, can prevent the leakage of electronic labeling information, ensuring information security property can ensure to avoid the radio electronic label that be applicable to intelligent transportation that read query facility cause interference of this electronic tag to non-native system simultaneously.
The purpose of this utility model is achieved through the following technical solutions: the radio electronic label that is applicable to intelligent transportation, it comprises antenna, rf receiver unit, radio frequency transmitting element and control module, described radio frequency transmitting element comprises SK back-modulation circuit, up-converter circuit, bandwidth-limited circuit and power amplification circuit, rf receiver unit comprises that connecing envelope produces circuit and detecting circuit, control module comprises coding-decoding circuit, microprocessor and storer, the output of antenna produces circuit by envelope successively and is connected coding-decoding circuit with detecting circuit, coding-decoding circuit is connected with microprocessor, microprocessor is connected with storer, the output of coding-decoding circuit is successively by SK back-modulation circuit, up-converter circuit, bandwidth-limited circuit is connected antenna with power amplification circuit.
Described electronic tag also comprises a power generation circuit and mu balanced circuit, and the output of power generation circuit is connected with mu balanced circuit, and the output of mu balanced circuit is connected with radio frequency transmitting element, rf receiver unit and control module respectively.
The beneficial effects of the utility model are: be provided with rf receiver unit, radio frequency transmitting element and control module, can sending and receiving signal, label information can be sent, can prevent the leakage of electronic labeling information, ensuring information security property, can ensure to avoid this electronic tag to cause interference to the query facility that reads of non-native system simultaneously, easy to use, be highly suitable for the place that the demands such as sales field are large and floating population is many.
