Abstract
The invention relates to a USB (Universal Serial Bus) mobile hard disk capable of reading and writing a RFID (Radio Frequency Identification) label and a working method of the USB mobile hard disk. The USB mobile hard disk comprises a control chip, a USB interface used for connecting with a computer, a storage part and a RFID radio frequency chip; and the storage part and the RFID radio frequency chip are respectively connected with the control chip. The USB mobile hard disk disclosed by the invention has the advantages that: writing and reading of the RFID label is realized by a RFID control chip arranged in the USB hard disk; and meanwhile, read information not only can be stored in the mobile hard disk, but also can be transmitted to the computer through the USB interface, so that acquisition and storage of the information are combined, and the USB hard disk is convenient to carry and store.
Description
Technical field
The present invention relates to a kind of USB portable hard drive and method of work thereof of read-write RFID label.
Background technology
REID (Radio Frequency Identification; Abbreviation RFID); Be a kind of automatic identification technology that begins to rise the nineties in 20th century, REID 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.The RFID RF identification is a kind of contactless automatic identification technology, and it is through the automatic recognition objective object of radiofrequency signal and obtain related data, and identification work need not manual intervention, can work in various rugged surroundings.The RFID technology can be discerned high-speed moving object and can discern a plurality of labels simultaneously, and is swift and convenient to operate.RFID is a kind of simple wireless system, has only two basic devices: RFID label and card reader.Basic functional principle is also uncomplicated: after label gets into magnetic field; Receive the radiofrequency signal that plug-in reader sends, rely on the energy that induction current obtained to send out the product information (Passive Tag, passive label or passive label) that is stored in the chip; Perhaps initiatively send signal (the Active Tag of a certain frequency by label; Active label or active tag), after plug-in reader reads information and decoding, deliver to CIS and carry out the relevant data processing.Its working frequency range is a low frequency, high frequency, ultrahigh frequency and microwave section.
In the prior art, the RFID card reader be that two of portable hard drives are independently individual, the both can have USB interface, but function is separate.Such weak point is stored with regard to portable hard drive only, and card reader can only be read and write rfid card, and its memory capacity is very little, can not store magnanimity information,
Summary of the invention
The objective of the invention is both to be combined effectively, realized the function of read-write storage magnanimity information in order to provide a kind of, and the USB portable hard drive of read-write RFID label very convenient to carry.
The objective of the invention is to realize: the USB portable hard drive of read-write RFID label of the present invention by following technical proposals; Comprise control chip; And the USB interface of connection control chip and computer; Reach the storage area and the RFID radio frequency chip that link to each other respectively with control chip, and the label that links to each other with the RFID radio frequency chip.
Further, transmission has control information and data message between said control chip and the RFID radio frequency chip, and transmission has control information and data message between said control chip and the storage area.
Further, transmit between said RFID radio frequency chip and the label and read and write data.
Another object of the present invention is in order to provide a kind of both to be combined effectively, has realized the function of read-write storage magnanimity information, and the method for work of the USB portable hard drive of read-write RFID label very convenient to carry.
The objective of the invention is to realize: link to each other the control chip of USB portable hard drive with the RFID read-write chip by following technical proposals; Realize read-write through control RFID chip to the RFID label; Simultaneously can be in portable hard drive the information stores that reads; Also can be transferred in the computer and go, thereby unite two into one the collection of information and storage through USB interface.
The present invention has following advantage: the control RFID chip through being arranged in the USB hard disk is realized the read-write to the RFID label; Simultaneously can be in portable hard drive the information stores that reads; Also can be transferred in the computer and go through USB interface; Thereby unite two into one the collection of information and storage, easy to carry, be convenient to storage.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further
Fig. 1 is a schematic diagram of the present invention.
Embodiment
Referring to Fig. 1, the USB portable hard drive 1 of read-write RFID label of the present invention comprises control chip, is connected USB interface, storage area and the RFID radio frequency chip of usefulness with computer, and storage area links to each other with control chip respectively with the RFID radio frequency chip.Transmit between said RFID radio frequency chip and the RFID label and read and write data.Transmission has control information and data message between said control chip and the RFID radio frequency chip, and transmission has control information and data message between said control chip and the storage area.
Method of work of the present invention is: link to each other the control chip of USB portable hard drive 1 with the RFID read-write chip; Realize read-write through control RFID chip to the RFID label; Can the information stores that reads in portable hard drive, also can be transferred in the computer and go, thereby unite two into one the collection of information and storage simultaneously through USB interface; Easy to carry, be convenient to storage.
Below only with an embodiment mentality of designing of the present invention is described, under the situation that system allows, the present invention can expand to external more function module simultaneously, thereby expands its function to greatest extent.
The above is merely embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
