Description

A kind of RFID label chip
Technical field
The present invention relates to field of radio frequency identification, relate in particular to a kind of RFID label chip.
Background technology
RFID is a REID, claims electronic tag, radio frequency identification again, can discern specific objective and read and write related data through radio signals, and need not to set up machinery between recognition system and the specific objective or optics contacts.The ultimate developing goal of Internet of Things is exactly for all personnel and article installation RFID label, utilizes the reader device and the network equipment can obtain the various information about personnel and article whenever and wherever possible.Comprise RFID label chip and label antenna in the RFID label, also contain battery sometimes.
According to the difference of RFID label chip energisation mode, can the RFID label be divided into following three types: 1) passive electronic label.There is not battery in the passive electronic label; Label antenna obtains to supply RFID label chip work capacity through space magnetic field coupling or electromagnetic radiation from reader, will be stored in identifier in the RFID label chip internal memory again and be modulated on the radiofrequency signal with other data message and launch.Owing to do not have battery, passive electronic label can do very thinly, very little, do not receive the influence of battery electric quantity its serviceable life, can reach more than 10 years; The cost of passive label is low, is used widely in fields such as Commercial goods labels, goods logistics, ticket anti-pseudo, transportation card, taking care of books, access control and attendances.But wet environment or near metal can greatly influence the reading performance of label; And, passive electronic label read distance limited in emission power of reader.Cooperate the reader meet international standard, the high frequency passive electronic tag read distance less than 1 meter, the distance that reads of ultra-high-frequency passive electronic tag generally also is no more than 10 meters.2) active electronic label.The RFID label chip of active electronic label is supplied power by internal battery, and it continues times without number the identifier in the internal memory and other data message to be modulated on the radiofrequency signal to launch.The reading performance of active electronic label is fabulous, and it reads distance and can reach more than 100 meters, and it is less influenced by environment for use.But because active electronic label contains battery, its serviceable life is shorter, and generally below 3 years, and the signal radiation pattern that continues repeatedly also can cause a large amount of electromagnetic pollutions; The consumption of active electronic label causes its cost higher, even reaches more than 10 times of passive label much smaller than passive label at present.3) half active electronic label.The RFID label chip of half active electronic label is supplied power by internal battery, but the RFID label chip is in dormant state always at ordinary times; When half active electronic label during through the reader antenna irradiation field region, the RFID label chip entering duty that is triggered is modulated at the identifier in the internal memory and other data message on the radiofrequency signal and launches; After electronic tag left the aerial radiation place, the RFID label chip recovered dormant state, no longer outwards transmits.Half active electronic label can have very long serviceable life, also can not cause electromagnetic pollution, and it is very little influenced by environment for use simultaneously; But the texture ratio active electronic label of half active electronic label is complicated more, and cost is also higher.
At present, the plurality of applications scene requires to use simultaneously passive electronic label, active electronic label and half active electronic label; For example, secret Articla management system requires pasting electronic label on secret article such as paper document, movable storage device, mobile phone, camera; Use passive electronic label, frivolous portable on the paper document; Comprise a large amount of metalworks in movable storage device, mobile phone and the camera, need to use half active electronic label to improve reading performance; But the RFID label chip on the market is all only supported a kind of energisation mode, and the air interface protocol that the RFID label chip of different energisation modes adopts is different, needs to cooperate reader separately to use; Therefore; If existing RFID label chip product on the employing market; Just must be respectively paper document and other article configuration two cover rfid systems, they use air interface protocol separately, reader separately; Could the data that obtain be gathered to background process at last, increase the complexity of system.
