Description
Technical field
The present invention relates to wireless communication field, more particularly, relate to a kind of electronic tag and know method for distinguishing and device fast.
Background technology
Radio-frequency (RF) identification (RFID, Radio Frequency Identify) is a kind of contactless automatic identification technology, and it automatically identifies destination object by radiofrequency signal and obtains related data, and the work of identification need not manual intervention, can work in various rugged surroundings.REID identifiable design high-speed moving object also can identify multiple label simultaneously, swift and convenient to operate.The basic functional principle of REID is as follows: reader sends radiofrequency signal to the label in its electromagnetic field areal coverage, after the radiofrequency signal that label reception reader sends, the energy obtained by means of induction current sends out storage product information in the chips (for passive label or passive label), or the energy that provides of the battery utilizing label to carry sends the signal (for active label or active tag) of a certain frequency; Active label initiatively can send radiofrequency signal to reader.Reader reads information and after decoding, delivers to application system and carry out relevant data process, to reach identification to on-site label and Data Collection.
At present, different radio-frequency recognition systems is different with technical requirement and adopt different communication meanss according to embody rule.Such as, international standard ISO 18000-6 and ISO 18000-7 respectively specification be operated in the communication means of the passive radio frequency identification system of 900MHz and be operated in the communication means of active radio frequency identification system of 433MHz.2.45GHz frequency range is worked at the active radio frequency identification system of the military radio-frequency (RF) identification air interface protocol definition of China GJB 7377.2-2011.
Usually, a radio-frequency recognition system is made up of a reader and multiple label, and therefore, above-mentioned communication means is in the method for field of radio frequency identification also referred to as reader counting label or identification label.Particularly, the reader specified in ISO 18000-6 type C and the method for label communication are: reader is initiated one check the cycle by being sent querying command (Query), after label receives this querying command, according to command parameter Q at random 0 to 2
qselect an integer in-1 scope, select the transmission of 0.The label sent carries 16 random number R N16 as temporary identity ID simultaneously, if send successfully, with this ID for identity information completes discriminating between reader and label.Differentiate successfully, reader sends the information that the order reading tag of point-to-point is carried, and such as: EPC(Electronic Product Code, electronic article is encoded), TID(Tag identifier, tag identification number) etc.In addition, reader can complete write operation by order.Do not send successful label, wait for that next querying command (Query) responds again.Reader is according to the reception result adjustment Q value of current time slots.In general, the once complete process of checking that this communication process defines completes following three tasks: the first, is completed the access (also referred to as multiple labels anti-collision) of label by querying command (Query) and related command; The second, be that temporary identifier information carries out corresponding identity verify with RN16; 3rd, reader carries out read-write operation by order to single label.
Particularly, the reader specified in ISO 18000-7 and the method for label communication are: reader sends specific waveform as wake-up signal, wakes the label being in dormant state up.After label is waken up, the collection order (Collection) that wait-receiving mode reader sends.After label receives this collection order, in a time window, a timeslice is selected to reply the information (namely selecting a time slot in the CDMA slotted ALOHA of framing in a frame to send the information of oneself) of oneself according to stochastic parameter.After reader receives a time window (or a frame), the successful label of transmission is confirmed, further reading tag information simultaneously, such as UDB(Universal Data Block, generic data block), read successfully and send sleep command, after this label receives sleep command, enter dormant state, later collection order cannot be responded, until after being waken up next time.Do not send successful label, in follow-up time window, reselect timeslice and send.Reader is according to the situation adjustment window size received in current time window.In general, the once complete process of checking that this communication process defines briefly can be divided into an awake period and multiple collection phase.The collection phase can be divided into again sync period, listen period and confirmation phase.Specifically, in awake period, reader sends the wake-up signal of certain time length, to wake the label being in dormancy up.In the collection phase, reader sends collects order, synchronous all labels, and the reply intercepting label in follow-up listen period (time window).After intercepting end, reader carries out the read-write operation of point-to-point to successful label, namely confirms the phase, and the label of end of operation proceeds to dormancy by order.This collection phase constantly adjusts and repeats until all labels are all checked complete.
Particularly, the reader specified in GJB 7377.2-2011 and the communication means of label are: label is in dormant state or periodicity dormancy/wake states usually, before reader and label communication, must be waken up by label by outside waken system or ensure that label is in wake states, the communication process of reader and label be divided into awake period, access periods, collection phase and session phase.Reader sends incoming order to the label being in wake-up states, and according to the anticollision protocol set in advance, makes all label accesses waken up, and is that each label distribution accessed represents that it is at the collection time-gap number collecting time slot position in time slot; Reader sends collects order, and the time slot position of the collection time slot that the collection time-gap number that label receives according to it determines will be collected the data that instruction (collection is ordered) requires and be transferred to reader.Carry out the communication of point-to-point at session phase reader and label, afterwards, reader sends sleep command and makes label be in dormant state.
Can see, in above-mentioned active radio frequency identification system, label needs when not checking or outside identifying to be in dormant state usually, to save tag energy, thus obtains longer serviceable life.Therefore, before label is identified, usually can send the wake-up signal of certain time length, to activate label, open label communication module.After label is activated, usually can perform a predetermined anticollision protocol or algorithm, to reach the access of many labels, afterwards after read write line obtains the TID of label, then carry out two-way data interaction with label.For the identification of rapid movement label, some is complicated for such treatment scheme, makes recognition speed unhappy, even when tag motion speed is high or the traffic is large, is difficult to the successful identification ensureing label.
