Microcomputer unit 145 is by communication cable 150 from associated system master computer receive information signal.This A little information signals include the identification for the given file being required.

As shown in figure 8, each file 130 has the structure in traditional U-shaped section, the structure has been demonstrated to set in office It is popular to contain file in standby industry.Every one side (front and back) of file 130 is all by the mechanical twelve Earthly Branches of mechanical prop Support.One (pillar 148) in pillar is single structure and comprising single rigid non-conductive arm, the downward folding that the arm has Folded hook-shaped end slideably coordinates with supporting guide 128 and 129.Other pillars (pillar 152) have spy according to the present invention Different structure.

Referring to Figure 10, it is the front view of pillar 152, and the element includes main non-conductive support element 154, works as file When folder is correctly positioned in document drawer, the hook-shaped end 156 and guide rail of the downward torsion that the element 154 has in every one end That being associated in 128 and 129 is engaged.Pillar 152 is preferably made up of printed circuit board material, in the printed circuit The circuit pattern of conduction can be formed on plate material and circuit unit can be installed.Include a pair of crystal 161 and 162, integrated circuits 163 And a pair of LED indicators 164 (LED A) and 165 (LED B) radio-frequency responsive circuit are installed on pillar 152.This is included The circuit of crystal 161 and 162, integrated circuit 163 and LED indicator 164 and 165 preferably by proper circuit node it Between pillar 152 on and the hook-shaped end when file 130 is suspended in midair by guide rail 128 and 129 in face of the surface of guide rail 128 and 129 Conductive path is provided on 156 surface, and is electrically connected between the hook-shaped end 156 of pillar 152.LED164 and 165 is by following Mode is mechanically supported by pillar 152：The top of the top edge of file 130 is projected into, so that when opening document drawer 118 Two LED are can be seen that above file.

Figure 11 is a schematic plan, and it shows that multiple file clamp circuits can be physically located at the side in monofile drawer Formula.As shown in this figure, each in file clamp circuit 161i-165i is carried out across conductive supporting guide rail 128 and 129 Electrical couplings, all circuits are all connected in parallel.Current detection circuit 139 have be coupled in guide rail 129 first node and The Section Point for the microcomputer unit 145 being coupled in shown in Fig. 9.Choking-winding 138 is coupled in guide rail 128 and dc source Between that associated power output terminal of switch 148.Capacitor 137 is coupled in the phase of guide rail 128 and RF switch 147 Between that RF output end of association.

Figure 12 is incorporated into the schematic diagram of the file clamp circuit of the file pillar 152 of each file.Such as the accompanying drawing institute Show, each file clamp circuit includes a pair of crystal 161 and 162, and this pair of crystal is coupled in associated in parallel by capacitor 137 The guide rail 128 of drawer.Each pair crystal 161 and 162 in given file clamp circuit all has the resonant frequency of a pair of combinations, should It is different from the resonant frequency of the paired crystal in alternative document clamp circuit to resonant frequency.All resonant frequencies are preferably in light In the radio-frequency region of spectrum, and the value in the range of desirable about 2mHz to about 20mHz.Frequency separation between crystal belongs to design The category of selection, and separate crystal in the range of 2mHz-20mHz by using 0.001MHz minimum frequency and obtained Good result.When radiofrequency signal is appeared on guide rail 128, the signal is by capacitor 137 and concurrently appears in crystal On 161 and 162.If radiofrequency signal and any one in crystal 161 and 162 (or both) frequency match, frequency matching Crystal will occur resonance and low resistance is presented to the radio-frequency current that passes therethrough.The electric current is by switching transistor 167, and the latter will Activate single-shot trigger circuit 168.If two single-shot trigger circuits 168 are all activated, the output that they are combined will start AND (with) Door 169, the latter is with that will light LED164 to indicate：File has been identified.At the same time, the electricity of the drawer residing for file Current sensor 139 will light drawer panel LED 127 in mode as described below.

In order to meet the constraints for the broadcast radiation power carried out by government organs, and in order that it is contained in each file The power demand of radio-frequency signal generator 146 in cabinet 110 is minimized, and the preferred technique for producing radiofrequency signal is in two crystal Radiofrequency signal is alternately generated at 161 and 162 resonant frequency.This figure 13 illustrates.Such as the accompanying drawing (is it illustrates one Radio frequency output signal from radio-frequency signal generator 146 on the system cycle) shown in, radio-frequency signal generator produces the frequency in several cycles first For f1 radiofrequency signal, the signal is terminated up to of short duration time phase, the frequency in several cycles is then produced and believes for f2 radio frequency Number, and the signal is then terminated up to of short duration time phase.The cycleoperation is repeated up to the time of sufficient length to ensure：Operation Person has time enough (by observing the drawer LED127 and file LED164 lighted) to enter correct file cabinet and drawer Row positioning.If handled overlapping by existing between crystal 161 and 162 radiofrequency signal, correct file clamp circuit LED164 will be just remain on.As long as electric current is taken out by one in file clamp circuit as caused by the resonance of crystal 61 and 62 Drawer LED127 will be just remain on.

Figure 14 is the schematic diagram of the current detector 139 of each drawer in file cabinet 110.As shown in this figure, along leading The first reference that the DC current that rail 129 flows through is coupled in operational amplifier 173 by diode 171 and filter network is defeated Enter.Reference threshold D. C. value is provided to other reference inputs of operational amplifier 173.The value of DC reference voltage can be by changing Become the resistance of variable resistor element 174 to be adjusted.

As long as one in file clamp circuit is work (that is, crystal 161 and 162 is in resonance), just will be in guide rail 129 It is upper enough electric currents occur to produce activation signal in the output of operational amplifier 173.The signal is coupled in miniature calculating Machine unit 145, the latter responds to produce enabling signal to light correct drawer front LED127 and activate correct Drawer-lock 141.

In order to retrieve specific file from the file in system, operator believes to the search of system master computer input file Breath, the system master computer includes the complete list of the file cabinet residing for file, file and each file.System analytic accounting Calculating prow first asks file the microcomputer unit 145 being sent in correct file cabinet 110 to be remembered according to system Record is positioned to the file residing for searched file, and the activation file cabinet radio frequency letter of corresponding microcomputer unit 145 Number generator 146 and RF switch 147, the radiofrequency signal of appropriate rf frequency pair is supplied to together with dc source Searched file should be residing drawer.If the file searched is located in correct drawer really, miniature calculating Machine unit 145 receives feedback signal from drawer current detector 139 and produced for drawer front LED127 and drawer-lock 141 Operation signal.If operator opens the drawer that drawer front LED127 is lit, the file LED164 being lit will refer to Show correct file.

Once file is found by file positioning system components, then local microcomputer 145 is just by the event It is sent to system master computer.As response, system master computer produces file identifier signal and transmits the signal to position RFID reader 143 in the file cabinet 110 comprising found file 130.RFID reader 143 produces radio frequency files-designated Request signal is signed, the latter is transferred into all in the drawer of file 130 comprising finding by RFID reader antenna 144 File.If corresponding to the file of the file identifier signal is appeared in any file included in drawer, with this The associated RFID tag of file will make sound according to the RFID protocol realized to the request signal from RFID reader 143 Should.For example, the label can be responded by transmitting the signal comprising the content for after tag identification information being this document. When RFID reader 143 receives the information by RFID reader antenna 144, it relays the letter to the system master computer Cease to use later.If RFID reader 143 is not received by response, RFID reader within the period of pre-selection 143 can be repeated to the transmission of RFID reader antenna 144 according to the system protocol set up, or file is not found to signal transmission Return system master computer.

Radio-frequency signal generator in each file cabinet 110 may include frequency-sweep generator, the frequency-sweep generator The radiofrequency signal of pairing can be produced with scan pattern, it is split from first resonant frequency of a crystal in file management system Begin, and to last resonant frequency of a crystal in the system to terminating., can be every by instruction by this signal generator Microcomputer unit 145 in individual file cabinet 110 activates radio-frequency signal generator with scan pattern, so as to rapidly check text The integrality of the whole set of part folder.As the signal frequency of pairing is scanned in gamut, given file cabinet 110 is appeared in In All Files clamp circuit all will at its respective frequency resonance, and this can be by using traditional rf detector circuit Detected by the microcomputer unit 145 in each file cabinet 110.The file of any loss all without responding, and This can also be detected by using identical circuit by the microcomputer unit 145 in each file cabinet 110.It is any to be detected To loss file can from the given microcomputer unit 145 in each file cabinet 110 to system master computer report, and The file identification being associated with by system master computer by recording the frequency of non-response file clamp circuit in computer.

Similarly, think that the All Files recorded in the system sequentially produces text by operating system master computer Part identifier signal, can check the integrality of the whole set of file in the system.Master computer first knows each file Not Fu signal send the RFID reader 143 into file cabinet 110, (according to system master list) correspond to this document identifier letter Number file assume be located at this document cabinet 110 in.RFID reader 143 in this document cabinet 110 then produces request signal And wait-for-response.If receiving response, the event has found signal by RFID reader 143 as file and has sent back system master Computer.If being not received by the response to the request signal, the event does not find signal as file and read by RFID Device 143 is taken to send back system master computer.System master computer can run to this with the different drawers to file cabinet 110 RFID reader 143 of the instruction into the same file cabinet 110 of file transmission file inquiry signal resend identical File identifier signal.If having obtained file has found signal, system master computer will update the system record to remember Record the new drawer positions of file.If cannot from the inquiry of the All Files in all drawers of the cabinet 110 of original selection File has found signal, then system master computer can run to this and be sent with the All Files cabinet 110 sequentially into system Identical file identifier signal and the response for waiting the RFID reader 143 in alternative document cabinet.If do not received Response is found to file, then this document then can be added to by system master computer loses listed files.If from the system One in cabinet 110 in system receives file and has found response, then system master computer may be updated the master list of file to remember Record the new position of this document.

Initially system can configured in several of different ways for file.Most basic mode is：By single file Folder 130 is placed in the drawer in file cabinet 110, cabinet radio-frequency signal generator 146 is scanned the scope of pair frequency, is recorded at this The frequency of resonance, the list frequency number inputted in the memory of microcomputer unit 145 occur for the crystal in file In, this document folder is removed, another file is inserted, and continuously repeat the process for file in need.Once it is all File be processed, transmit appropriate from the microcomputer unit 145 of given file cabinet 110 to system master computer File identification information.This method is equally applicable to that file is not present and is initially required the new system of lesser amt file System.A kind of more useful technology is：The first file is inserted into drawer, the rf frequency pair allowed is scanned, resonance is recorded Frequency, by the new list of the numeral input；While the first file is not removed the second file, scan frequency are inserted to drawer It is right, the resonant frequency of the new folder is added to the list；The 3rd file, scan frequency pair, to described are inserted to drawer The resonant frequency of the 3rd file is added in list；Etc..As each new file is inserted into drawer, miniature calculating Machine unit 145 has the operation list for having recognized frequency, and because each crystal frequency is to being unique, does not have repetition.

For log file in systems, by using being coupled in the keyboard of system master computer manually, or by using The label reader of system master computer is coupled in, the RFID tag number of given file is input in system master list.With Together, the identification of the file residing for the description of file content and this document is input to system chief series to RFID tag number by operator In table.As new file is added, the process is performed for the new file information, so that in any given time, the system Master list includes the full directory of the file cabinet and drawer positions of All Files and file and each file in system.
