For consumer goods enterprises such as drinks, can realize producing and the management of storage automation data.For agent agency and wholesale link, can the effective monitoring management, stop falsifying, store goods, phenomenon such as supply shortage, stop mistake and play tricks.Each commodity for the turnover storehouse are read and write tracking immediately, turnover need not be devaned during the storehouse, can carry out " long-range, automatic, group read ", with UNICOM at any time of data center, for dispatch from the factory the back or deliver from godown after do not arrive the appointed place on time each commodity can in time find and follow the trail of.For finding defective in quality or other have the commodity of customer complaint unusually, can trace to the source and search tracking.Commodity are behind large-scale point-of-sale terminal (super as discussing, restaurant etc.), the sales counter of selecting client, the ground that the cashier of clearing and client walk out front door all can be provided with the read write line that reads information automatically, and show by large electronic display and the consumer to have a mind to the consumer of the true and false and announcements inquire about.
Point-of-sale terminal for retail forms such as convenience store, buffets, the consumer can read the information of the RFID chip on the commodity by handheld RFID read write lines such as mobile phones, and with the information uploading that reads to the public service anti-counterfeiting platform, receive the Query Result that the public service anti-counterfeiting platform is returned then.
Above-mentioned commodity are from manufacturer production, storage, sale agent, until in each link of last large-scale point-of-sale terminal, the frequency of operation of the RFID chip on the commodity is ultrahigh frequency (between the 860MHz-960MHz), the RFID chip is positioned at the far-field region of reading and writing device antenna radiation field, and its reading/writing distance is generally greater than 1 meter.Frequency of operation for RFID chips that the handheld RFID read write line read such as mobile phones then is high frequency (13.56MHz), when RFID chip and hand-held read write line carry out exchanges data, the RFID chip must be positioned at the near field region of hand-held reading and writing device antenna radiation, and its reading/writing distance is generally speaking less than 1 meter.At present, the handheld RFID read write line also can't be read and write the ultrahigh frequency RFID chip, and the ultrahigh frequency system price is higher, generally be about 10 times of radio frequency system, therefore, the handheld RFID read write line being changed into ultrahigh frequency reader-writer (ultrahigh frequency reader-writer for example is installed) on mobile phone is unpractical settling mode; In addition, the RFID chip (ultrahigh frequency RFID chip and high-frequency RF ID chip) of two different operating frequencies is installed simultaneously on commodity, its cost is higher, and is also inadvisable.
The utility model content
Technical problem to be solved in the utility model is, a kind of lower-cost double frequency rfid system of taking into account ultrahigh frequency and high frequency is provided.
For solving the problems of the technologies described above, the utility model provides a kind of double frequency rfid system, comprise dual-band chip and the dual-band antenna that is connected with described dual-band chip, described dual-band chip comprises the first storage arithmetic element, second storage arithmetic element and the radio frequency unit, the described first storage arithmetic element comprises first memory module and is used for ultra-high frequency signal is carried out first computing module of calculation process, the described second storage arithmetic element comprises second memory module and is used for high-frequency signal is carried out second computing module of calculation process that described radio frequency unit is simultaneously with described first, the second storage arithmetic element is connected; Described dual-band antenna is connected with radio frequency unit, and it comprises the high frequency antenna that is used to receive/launch the ultra-high frequency antenna of ultra-high frequency signal and is used to receive/launch high-frequency signal.
Further, described high frequency antenna is around the periphery of described ultra-high frequency antenna.
Further, the disposable etching of described dual-band antenna forms.
Compared with prior art, the dual-band chip of above-mentioned rfid system has increased by one group of storage arithmetic element on the basis of existing chip, and two groups of storage arithmetic elements are connected with radio frequency unit simultaneously, and dual-band antenna comprises ultra-high frequency antenna and high frequency antenna; When using ultrahigh frequency reader-writer that the RFID dual-band chip is read and write, radio frequency unit receives the signal by ultra-high frequency antenna reception/emission, and one of them computing module is handled this signal; And when using the high frequency read write line that the RFID dual-band chip is read and write, radio frequency unit receives the signal by high frequency antenna reception/emission, by another computing module this signal is handled.Above-mentioned rfid system only uses a dual-band chip to discern ultrahigh frequency and high-frequency signal simultaneously, need not to install on mobile phone ultrahigh frequency reader-writer, also need not to increase on commodity chip, and therefore, its cost is lower, and volume is less, installs more convenient.
