Abstract
The invention relates to a RFID intelligent reader-writer with multiple frequency bands and protocols. The reader-writer comprises a radio frequency band module, a radio communication module, a data conversion module and a data processing module. The radio frequency band module is provided with a plurality of antennas with different received frequencies, when a RFID label approaches the reader-writer, the radio frequency band module chooses the antennas according to different frequencies. The radio communication module judges whether a protocol for communication with the RFID label exists; if no, the radio communication module downloads a new protocol from the Internet to be stored in the radio communication module and receives data according to the new protocol; if yes, the radio communication module directly receives data, the received data is transmitted to the data conversion module to be converted into data with uniform format, the converted data is transmitted to the data processing module to be finally processed, and the processed data is transmitted to a PC through a serial port. Compared with the prior art, the invention has the advantages of wide application range, and the like.
Description
Technical field
The present invention relates to a kind of rfid interrogator, especially relate to a kind of multiband multi-protocols RFID intelligent read-write device.
Background technology
REID (Radio Frequency Identification; Abbreviation RFID); Being a kind of automatic identification technology that begins to rise the nineties in 20th century, is the technology that the information utilizing radiofrequency signal to pass through space coupling (alternating magnetic field or electromagnetic field) the contactless information transmission of realization and pass through to be transmitted reaches identifying purpose.Through on goods etc., adhering to the RFID chip that stores identifier, and through radiowave from this RFID chip exterior read this identifier information and come goods etc. is managed.Emitting radio wave is called rfid interrogator with the equipment that reads identifier information.Rfid interrogator not only can read the identifier information of storing in the RFID label.But also can in the RFID label, write other information, thereby make RFID can carry out various application.
Under situation about communicating through use radiowave and RFID label, rfid interrogator must communicate with the RFID label and how be provided with regardless of the RFID label, otherwise the scope of application of rfid interrogator will be severely limited.Traditional RFI read write line is merely able to read the RFID label of one or both frequency bands; Use more and more international today at RFID; This read write line can not satisfy the harbour, on the railway employing different RF ID label on the different containers is read the demand of management.If the harbour adopts traditional rfid interrogator to read on the railway,, all need a corresponding read corresponding with it so to the RFID label of different manufacturers different model.Like this, the use of RFID on railway will be very limited.
Software radio (software radio) utilizes different programmable software approachs to realize needed radio system on the common hardware platform of an opening.Be called for short SWR.But desirable software radio should be a kind of radio of all software programmings, and to have maximum dirigibility with radio platforms be characteristic.Whole radio frequency able to programme (RF) wave band, channel access way and Channel Modulation of comprising able to programme.The basic thought of software radio is to be support with general a, standard, modular hardware platform, realizes the various functions of wireless station through software programming, from based on hardware, towards the Radio Design method of purposes, free.The software implementation of function realizes certainly will requiring to reduce the hardware circuit of function singleness, very flexible, especially reduces the simulation link, tries one's best digitized processing (A/D and D/A conversion) near antenna.Software radio is stressed the opening and comprehensive programmability of architecture, changes hardware configuration structure through software upgrading, realizes new function.Software radio adopts standard, high performance open bus structure, is beneficial to the continuous upgrading and the expansion of hardware module.
Summary of the invention
The object of the invention is exactly to provide a kind of usable range wide multiband multi-protocols RFID intelligent read-write device for the defective that overcomes above-mentioned prior art existence.
The object of the invention can be realized through following technical scheme:
A kind of multiband multi-protocols RFID intelligent read-write device is characterized in that this read write line comprises radio-frequency module, radiocommunication module, data conversion module, data processing module; Described radio-frequency module is provided with a plurality of receive frequency different antennas, and when RFID label during near this read write line, radio-frequency module is selected antenna according to different frequencies; Radiocommunication module judges whether the agreement that exists this RFID label communication to use; If not, then radiocommunication module stores New Deal in this radiocommunication module into through the mode of network download, and receive data according to this New Deal; If yes; Then directly receive data, the data transmission that receives is given data conversion module, and this data conversion module is the data of consolidation form with data conversion; Be transferred to data processing module through data converted and do last processing, treated data are transferred to PC through serial ports.
Described data processing module processing procedure comprises eliminates redundancy in the data, and the correctness of verification msg and elimination misdata.
Compared with prior art, the present invention has the following advantages:
Multi-frequency multi-protocols RFID intelligent read-write device solves the disunity of the international standard of present RFID label well; Make the frequency of the RFID label that various countries are adopted in application such as container; Aspects such as over-the-air protocol are also inequality; And traditional rfid interrogator only has unifrequency or double-frequency reading capability, can not read problems such as various RFID label well.
This rfid interrogator can read to the RFID label of different frequency different agreement, has eliminated the bottleneck of traditional read write line single-frequency, makes that the application of RFID can be more extensive.And adopt fixing data layout, standard the use standard of RFID.
Description of drawings
Fig. 1 is the structural representation of a kind of multiband multi-protocols of the present invention RFID intelligent read-write device.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
As shown in Figure 1, a kind of multiband multi-protocols RFID intelligent read-write device, this read write line 6 comprises radio-frequency module 1, radiocommunication module 2, data conversion module 3, data processing module 4; Described radio-frequency module 1 is provided with a plurality of receive frequency different antennas 11, and when RFID label during near this read write line 6, radio-frequency module 1 is selected antenna 11 according to different frequencies; Radiocommunication module 2 judges whether the agreement that exists this RFID label communication to use, if not, then radiocommunication module 2 stores New Deal in this radiocommunication module 2 into through the mode of network download; And according to these New Deal reception data; If yes, then directly receive data, the data transmission that receives is given data conversion module 3; This data conversion module 3 just therefrom extracts valid data; And to be converted into a kind of length be 24 data layout, is transferred to data processing module 3 through data converted and does last processing, and treated data are transferred to PC through serial ports.
