In order to solve as above problem, increasing manufacturer requires to adopt RFID technology gather file data and carry out archives location, but adopts at present the system of RFID technical management archives also to have following problem:
(1) taking-up of archives and putting into, can not accomplish automatically to identify particular location and archive information, needs artificial scanning archives label, by input informations such as archival locations in database.
(2) even if there is archives positioning function, also can only locate when archives place layer or position, region, can not accurately navigate to the particular location of single archives.
Utility model content
For the above-mentioned defect of prior art, the utility model provides a kind of file data harvester based on RFID, can accurately locate in file cabinet single these archives particular location, and putting into, take out when archives can perception, and automatically gathers archives related data reporting system.
The utility model is by the following technical solutions:
A kind of file data harvester based on RFID, comprise file data acquisition module 1, file cabinet 6, be arranged in the electronic tag on archives 7 that sticks on of file cabinet 6, described data acquisition module 1 comprise single-chip microcomputer 2, by UART serial ports and single-chip microcomputer carry out the rfid interrogator 3 of data interaction, the switch arrays 4 that are connected with rfid interrogator 3 by RF cable, the aerial array 5 that is connected with switch arrays 4 by radio frequency microstrip line, described single-chip microcomputer 2 carries out switch control by IO control pair switch arrays 4.
Further, described data acquisition module 1 comprises: single-chip microcomputer 2, rfid interrogator 3, switch arrays 4, aerial array 5; Wherein, single-chip microcomputer 2 is connected with rfid interrogator 3 by serial ports, and single-chip microcomputer 2 is controlled mouth by IO and is connected with switch arrays 4, and rfid interrogator 3 is connected with switch arrays 4 by RF cable, and switch arrays 4 are connected with aerial array 5 by PCB microstrip line.
Further, described data acquisition module 1 is arranged on the front of file cabinet 6 and makes antenna and described electronic tag in described aerial array 5 corresponding one by one, the antenna distance of described aerial array 5 is consistent with archives width, within the distance between described antenna and label is controlled at the scope that can accurately read.
Further, between the archives of placing in described file cabinet 6, dividing plate is installed, clapboard spacing can fix or can corresponding described aerial array 5 in antenna spacing regulate.
Further, the distance between described aerial array 5 and described electronic tag is 3cm～4cm.
Further, described electronic tag is pasted on the ridge center position of described archives 6.
Further, described file data acquisition module 1 can carry out cascade expansion by serial ports.
The utility model, can locate in file cabinet single these archives particular location, and putting into, take out when archives can perception; In addition, can cascade communication between data acquisition module, after cascade, each module can scan archive information simultaneously, greatly promotes archives reading rate, facilitates post-production produce and safeguard simultaneously.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structured flowchart of the present utility model;
Fig. 2 is the schematic block circuit diagram of data acquisition module of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further.As shown in Figure 1, file data harvester based on RFID comprises file data acquisition module 1, is arranged in the electronic tag on archives 7 that sticks on of file cabinet 6, and wherein data acquisition module 1 comprises single-chip microcomputer 2, rfid interrogator 3, switch arrays 4, aerial array 5.Wherein, single-chip microcomputer 2 is connected with rfid interrogator by serial ports, and single-chip microcomputer 2 is controlled mouth by IO and is connected with switch arrays 4, and rfid interrogator 3 is connected with switch arrays 4 by RF cable, and switch arrays 4 are connected with aerial array 5 by PCB microstrip line.Aerial array 5 is PCB near field antenna, and the antenna spacing in aerial array 5 is consistent with archives width, to ensure that an antenna correspondence reads an archives label.In file cabinet 6, place the archives 7 that are pasted with electronic tag, label sticking is at the center position of archives 7 ridges, and its position is just corresponding one by one with PCB near field antenna.Archives label is fixed between 3cm-4cm to corresponding PCB near field antenna distance.File data acquisition module carries out cascade expansion by serial ports, and cascade quantity is determined by file cabinet length, reads complete whole file cabinet archives label data as foundation to meet.After module-cascade, as an overall work, each module is carried out cumulative coding automatically simultaneously, and provides external communication interface by a wherein serial ports of first cascade module.
Equipment when work, controls a mouthful Kai Heguan for gauge tap array 4 by module single-chip microcomputer by IO, successively gating with close the antenna in aerial array 5, meanwhile, single-chip microcomputer scans by serial ports control rfid interrogator 3 electronic tag reading on archives successively.Each module is responsible for monitoring the archives label in regional extent separately, in the time having archives to put into file cabinet, scan by module rfid interrogator 3, can read immediately the label data of putting into archives, and upwards sending data by serial ports one-level one-level, data comprise archives label data and the corresponding antenna of this archives present position information in file cabinet.Upper layer software (applications) is received after this packet, by analyzing and comparing, just can judge whether these archives have registration, and it is whether correct that it puts into position.In the time having archives to take out from file cabinet, file data harvester will detect that archives are removed immediately, and upwards send data by serial ports one-level one-level, data comprise in file cabinet which number file data is for empty, upper layer software (applications) can show it is which these archives of which file cabinet are removed, and determines whether to need to carry out sound and light alarm prompting.
