Description
Technical field
The utility model relates to a kind of administrative skill of RFID label, and especially the quick transmitting-receiving for large capacity RFID label designs without conflict, belongs to the RFID technical field.
Background technology
The RFID radio frequency identification is a kind of contactless automatic identification technology, it is automatically identified destination object and obtains related data by radiofrequency signal, identification work need not manual intervention, can work in various adverse circumstances, the RFID technology can be identified high-speed moving object and can identify simultaneously a plurality of electronic tags, and is swift and convenient to operate.The RFID label receives the radiofrequency signal that plug-in reader sends, and initiatively sends the signal of a certain frequency, after plug-in reader reading information and the decoding, delivers to CIS and carries out the relevant data processing.Management for the RFID label, from communication mechanism, can be divided into asynchronous and synchronous dual mode, the method of synchronization is suitable for the management of a large amount of RFID labels, sharing channel pattern such as ANT ultra-low power consumption wireless procotol, can support in theory to surpass 65000 labels and share an ANT passage, but the smallest passage cycle of ANT agreement support is 5ms that namely per second can only scan at most 200 labels, when facing the management of large capacity label, its very long scan period will be difficult to accept.Patent that Chinese patent literature discloses a kind of " multi-function electronic guiding system ", its Granted publication number is CN 201601683 U, Granted publication day is on October 6th, 2010, summary of the invention is to comprise central server, repeater, Radio Beacon, guide device, doorway machine totally 5 kind equipments, wherein, Radio Beacon, repeater, central server and doorway machine consist of the ZigBee wireless network, and by central server as network coordinator, guide device and Radio Beacon consist of active RFID system, and respectively as RFID label and read write line; When the visitor carries guide device and enters certain effective coverage, sight spot, guide device can be according to the selected languages of visitor, automatically carry out sight spot introduction and the prompting of peripheral sight spot track route with voice, two kinds of forms of literal, guide device also can be used as the calling set of seeking help, common MP3 player or FM broadcast receiver and uses; Central server can utilize the guide device coding of being uploaded by the Radio Beacon collection to carry out traffic statistics and target localization, can send the information of rejoining one's unit to guide device by Radio Beacon, the lowest signal threshold value that also can be triggered by dynamically arranging guide device reaches the effect of regulating the sight spot tourist flow." multi-function electronic guiding system " above-mentioned patent solution be the problem that the sight spot visitor is managed, handled number of labels also is restricted because of the control of sight spot number, for in the numerous and intensive zone of personnel, when such as school, hospital and other places student or patient being managed, need to concentrate situation to be divided into some residential quarters, the management system that framework is suitable by personnel.
Summary of the invention
The utility model is be used to the problem of management that solves large capacity RFID label, adopts synchronous mode, accomplishes the fast ability of a large amount of labels of response processing, and the RFID label has been realized again low power consuming simultaneously.
To achieve these goals, the utility model is by the following technical solutions: large capacity RFID label is received and dispatched fast without the conflict project organization, comprise beacon, receiver, the RFID label, described beacon and at least one receiver consist of a cellular cell system, described receiver and beacon adopt the frequency division multiplexing mode to work in different channel, described beacon adopts pure emission mode of operation, described receiver adopts pure reception mode of operation, described RFID label is active RFID tag, be provided with the timer of normally open in the described RFID label, described RFID label adopts the synchronous working pattern, and described RFID label and some cellular cells form the RFID label mobile networking system of cellular structure.Beacon works in pure emission mode, constantly sends the beacon broadcast bag; The RFID label is main receiving equipment, receives beacon, and is in due course, and changes channel, transmission information; Receiver operation receives the information of being sent by the RFID label in pure receiving mode, and receiver and beacon adopt the frequency division multiplexing mode, work in different channel; By beacon, receiver, RFID tag control system with the active RFID tag formation, combine frequency division multiplexing and high efficiency time-division multiplex technology, realized the information Quick Acquisition ability (can accomplish to scan for 1 second 4096 labels) of large capacity RFID label, the RFID label has also been realized low-power consumption (average operating current is controlled at 20uA) simultaneously; The principle of RFID label synchronous working is exactly that the RFID label is by adjusting the dormancy time of oneself, the beacon numbering of first beacon of receiving after oneself is waken up is just in time mated with RFID label self numbering, followed by, the transmission information that the RFID label just can be safe; The synchronous method of RFID label is to utilize opportunity and the beacon numbering of at every turn receiving beacon, with opportunity (predefine) and RFID label self numbering of intending receiving beacon, the side-play amount that draws, adjust the wakeup time in the time set, making wakes up next time just can correctly hit the beacon of coupling, obtains to send right, and the timer in the RFID label will remain at starting state, no matter catching or comparison value is set, all is undisturbed to the timer counting; Because the RFID label is when receiving beacon at every turn, all can rebuild one subsynchronous, so this synchronization mechanism does not have accumulated error; Each cellular cell is made of a beacon and one or more receivers, RFID tag scan channel (according to pre-set channel table acquisition beacon), to select the residential quarter of access, the frequency quantity of scanning is determined by the frequency reuse of Cellular Networks, after the RFID label is selected the residential quarter automatically, just can with the residential quarter in other RFID labels together, conflict free to receiver transmission information, simultaneously, the RFID label is according to the beacon situation real-time assessment channel quality that receives, when the beacon stealing rate reaches predetermined threshold, restart scan channel, the result of scanning will determine whether the RFID label continues to stay current area, perhaps enter a better residential quarter of channel quality, this label selects to access the method for residential quarter automatically, has realized the mobile networking ability of RFID label, expand the scope of activities of RFID label, also provide positional information for navigation system.
As preferably, the beacon broadcast bag of described beacon periodic transmission band serial number.The intensive transmission of beacon (short period) is with the beacon broadcast bag of serial number, and the emission of beacon is strict periodic, and numbering is gone round and begun again, and beacon is as the root of all time sequence informations.
As preferably, described RFID label activated once within each scan period, and the described scan period was no longer than 2 seconds.The RFID label most of the time is in resting state, the RFID label only when the beacon of receiving with self numbering coupling, transmission information; Because very short (in 2 seconds) of scan period design, for the also just greatly reduction of requirement of crystal precision, the crystal of common 40ppm precision can meet the demands.
Therefore, the utlity model has following beneficial effect: (1) can satisfy and the fast a large amount of tag control requirements of response processing; (2) realize the low power consuming of RFID label.
