Detailed description of the invention
As it is shown in figure 1, the profile storage system based on RFID of the present invention includes compact shelving.Compact shelving includes multiple storage space lattice, is used for depositing archives.Each storage space lattice have the numbering (numbering is allocated in advance) of these storage space lattice.Preferably, distributing storage space case marker label 1 for each storage space lattice, the storage of storage space case marker label 1 has the numbering of these storage space lattice, and described storage space case marker label are RFID label tag, and usually, described storage space case marker label are bonded on the crossbeam above or below storage space lattice.Preferably, each compact shelving can also have a label 4, stores the numbering of this compact shelving.
The archives of described profile storage system based on RFID storage have archives label, described archives label is RFID label tag, described archives label storage has Docket No. (allocating in advance), described archives label to be bonded on archives, and archives are placed in the storage space lattice of compact shelving.Archives order in storage space lattice is placed, and is placed in next storage space lattice after piling.
Archives label is different according to power consumption mode, can be divided into active label and passive label.For general storage area, its area is typically small, is preferably chosen passive label.Preferably, archives Tag Packaging becomes card-like or adhesive sticker papery, is affixed on archives or folder.
Described profile storage system based on RFID has reader 2 and antenna 3, reader 2 and antenna 3 and electrically connects.Antenna 3 is arranged in storage space lattice, and reader 2 is arranged on the correct position in the room that compact shelving is positioned at, such as ceiling or wall.Reader can connect background server, server controls reader read the information in the archives label in storage space lattice, naturally it is also possible to reads the information in storage space case marker label.Reader can also is that hand-held, integrated control module, staff's handheld reader, can make an inventory at scene.
During work, archives label and storage space case marker label are positioned at the far zone field of radiation field of aerial, and the coupled modes between label and antenna 3 are electromagnetic coupled mode.If employing passive label, radiation field of aerial provides radio-frequency (RF) energy for passive label, is waken up up by passive label.
Antenna reads the data in label and transmits the data processing module/chip to reader, processes data.Correspondingly, the data processing module/chip of reader can write data into archives label and storage space case marker label by antenna, such as, Docket No. writes archives label, by storage space lattice numbering write storage space case marker label.
Antenna 3 is typically beam antenna, the only electronic tag in antenna direction beam area and can be read or write.
It is limited to the tools range of RFID antenna, in each storage space lattice of compact shelving, places one group of antenna.So for multiple compact shelvings, the quantity of antenna is the biggest, and these antenna directly communicates with reader, no matter in terms of communication efficiency or in terms of communications cost, is all inappropriate.Therefore, middleware is set in reader and antenna, i.e. antenna branch device.Multiple antennas (such as 6-8) can be managed and distribute by one antenna branch device, thus archives label is carried out real-time tracking.The data that antenna reads are transferred to antenna branch device, transmit to reader via antenna branch device.Correspondingly, the topological diagram of a UHF RFID multiple antennas splitter is as shown in Figure 2.
Also show two-stage antenna branch device framework in fig. 2: a main antenna splitter and multiple from antenna branch device.Can connect multiple antenna from antenna branch device, the antenna data received from antenna branch device transmits to main antenna splitter, main antenna splitter transmit to reader.Correspondingly, the instruction that reader sends to from antenna branch device, by from antenna branch device transmission to certain or some antennas, reads the data in archives label or storage space case marker label via the transmission of main antenna splitter.
It addition, in order to save parking space, it is the closeest that compact shelving is placed, and archives or folder are also the closeest putting, and the interference of the radiofrequency signal between folder label is inevitable.Accurately managing of archives is needed to solve interference problem, and the setting that it is critical only that antenna therein.
Invention solves the read-write accuracy problem placing substantial amounts of archives label in little compact shelving grid.Such as, in the on-the-spot test of the first trial court of Beijing, use in the compact shelving grid of 85*23*25cm, place 50-80 archives.The density of archives label is very big, and label signal can interfere with each other, and the accuracy therefore read and write is a technical barrier the biggest.
In one embodiment, in storage space lattice, being respectively mounted an antenna at the two ends of storage space lattice, the archives in these storage space lattice are read by the two antenna in opposite directions.It is arranged on the two ends of storage space lattice, is for reciprocal signal effectively so that all of archives label can receive radiofrequency signal, and feeds back signal to antenna.The advantage of this antenna arrangement is that antenna coverage rate is big, apart from short.
But, this antenna arrangement also has shortcoming: the shortest owing to reading distance, wireless signal can interfere with each other, in this configuration, it is bad that ultra high frequency IC tag reads effect, preferably by using ultrahigh frequency electronic tag, each antenna reads distance maximum 50cm, and distance is the least, and signal is the most weak.It addition, under this layout, after antenna packages, thickness is too big, wants 5cm for one, 2 10cm to be accounted for can occupy storage space space.Through test, under above-mentioned antenna arrangement, discrimination of making an inventory reaches about 70%.
In another embodiment, in storage space lattice, installing an antenna at the top of storage space lattice, this antenna is main antenna, respectively installs an antenna at the two ends of storage space lattice, and the two antenna is auxiliary antenna.The gain of main antenna can be such as 9db, and the gain of auxiliary antenna can be such as 3db.Main antenna and the structure of two auxiliary antenna one semi-surroundings of formation.This antenna arrangement solve signal weak, apart from little problem, it is complete that advantage is that signal covers.Shortcoming is that both sides need for taking frame position 10cm, uses compact shelving and causes waste, and installation and deployment are pretty troublesome, affect file accessing.Through test, under above-mentioned antenna arrangement, discrimination of making an inventory reaches more than 85%.
In yet another embodiment, in storage space lattice, an antenna is installed at the top of storage space lattice, this antenna is main antenna, respectively installs an antenna at the two ends of storage space lattice, and the two antenna is auxiliary antenna, auxiliary antenna uses goat horn type aerial, increases center signal synthesizer simultaneously and coordinates.Center signal synthesizer is arranged on inner antenna, is allocated by signal and synthesizes, such as, be distributed transmitting the read signal come, and makes auxiliary antenna and top antenna work to read archives label, or the radiofrequency signal that label returns is synthesized.The gain of main antenna can be such as 9db, and the gain of auxiliary antenna can be such as 3db.Main antenna and the structure of two auxiliary antenna one semi-surroundings of formation.Goat horn type aerial is easy for installation, but goat horn type aerial is omnidirectional to be read, and can read the archives label in other storage space lattice, and therefore Signal averaging is complicated, and read false rate increases.This antenna arrangement solves installation question, and goat horn type aerial is easy for installation, and signal covers complete, but 360 degree of omnidirectionals read, and wireless signal interferes with each other, and Signal averaging is complicated, and the signal anticollision intractability of label strengthens, and equally exists and affects file accessing.Through test, under above-mentioned antenna arrangement, discrimination of making an inventory reaches more than 90%.
In order to accurately read the archives label in storage space lattice, it is critical that allow the aerial signal in these storage space lattice be evenly distributed in the bar shaped grid of storage space lattice as far as possible.In yet another embodiment, in storage space lattice, arranging multiple (such as 6-8) antenna, these antenna side by side, is coordinated by multiple signal synthesizers, and center signal synthesizer is the equipment that multiple miniature antenna signals are allocated and are synthesized；It is distributed transmitting the signal come and synthesizes.Signal synthesizer is arranged on inner antenna.This row's antenna forms a strip antenna row, length and the same length of storage space lattice.It is to say, this row's antenna occupies the length of storage space lattice substantially.Test according to storage space length, the optimal number of the miniature antenna that antenna package includes can be obtained, thus realize the most uniformly sending signal, disturb again minimum, optimal effect can be reached.The advantage of this antenna arrangement is that signal covers comprehensively, and archives label skip is few.But there is signal cavity problem, some positions do not have signal to cover all the time, cause a distinguishing label None-identified all the time；After folder somewhat adjusts position, i.e. can read.Through test, under above-mentioned antenna arrangement, discrimination of making an inventory reaches 95-98%.
Fig. 3 shows the structural representation of the antenna row including multiple miniature antenna (antenna oscillator) as above.This antenna package includes six uniform antenna oscillators 5, and length w of antenna row is basically identical with the length of compact shelving grid, so that signal uniform emission in grid.The radiofrequency signal of these six antenna oscillators carries out signal syntheses and distribution, and then and reader communication through signal synthesizer 6.
In yet another embodiment, in storage space lattice, arranging two row's antennas, often row's antenna comprises multiple (such as, 6-8) miniature antenna.Wherein row's antenna is arranged on the rear of storage space lattice, the i.e. inwall of storage space lattice, and another row's antenna is arranged on the top of storage space lattice, the i.e. top of storage space lattice.So, this two rows antenna can be for different angles, it is achieved wireless signal angle of coverage is complementary, makes archives label fully accept signal feedback signal.Archives label is read out, reading result is merged, thus obtain data more accurately.Through test, under above-mentioned antenna arrangement, discrimination of making an inventory reaches 99-100%.
Fig. 4 shows the topology layout figure of two antenna rows in this embodiment.One antenna row 7 is arranged on compact shelving top, and another compact shelving 8 is arranged on the back of compact shelving.90 degree of angles lined up by two antennas, and the length of two antenna rows and compact shelving same length.So can launch radiofrequency signal from different perspectives, improve the read rate of radio-frequency (RF) tag, and improve reading accuracy rate.
The present invention sends instruction by reader, radiofrequency signal can be sent on main split's device, the compact shelving storage space lattice that radiofrequency signal is forwarded to specify by main split's device from splitter, from splitter, signal is passed to each miniature antenna, radiofrequency signal is filled in the space of compact shelving storage space lattice, exciting archives label to return respective Docket No., the feedback signal received is transferred back to reader by each miniature antenna, such that it is able to be analyzed, comparison or make an inventory.
