Abstract
The utility model relates to a radio frequency identification (RFID) reader for a mobile phone. The RFID reader for the mobile phone comprises a RFID reader chip, antennas and a microcontroller, wherein the antennas are used for transmitting radio-frequency signals, the antennas are connected with the RFID reader chip, the RFID reader chip is connected with the microcontroller, the microcontroller is communicated with a microprocessor of the mobile phone through a communication interface, and the microcontroller and the RFID reader chip are integrated on one printed circuit board and are supplied power by a mobile phone battery. Due to the fact that the RFID reader is applied to or embedded in the mobile phone, the mobile phone has a function of reading RFID label. The RFID reader for the mobile phone has the advantages of being portable, and low in cost compared with the specialized handheld RFID reader. In addition, due to the fact RFID technology is integrated with the mobile phone which is gradually popular, the RFID reader for the mobile phone benefits wide popularization and application of the RFID technology.
Description
Technical field
The utility model relates to a kind of rfid interrogator, particularly relates to a kind of for the rfid interrogator on the mobile phone.
Background technology
RFID is REID, is a kind ofly can identify specific objective and read and write related data by wireless signal, and need not to set up the communication technology that machinery or optics contact between recognition system and specific objective.Two the most basic parts of rfid system are read write line and transponder (being electronic tag), its principle of work is that read write line is launched the radio wave energy of characteristic frequency to transponder, in order to drive transponder circuit the data of inside are sent, this moment, read write line just sequentially received and unscrambling data.As a kind of contactless automatic identification technology, the RFID technology is automatically identified destination object and is obtained related data by radiofrequency signal, identification work need not manual intervention, can work in various rugged surroundings, be widely used in a plurality of fields such as logistics, the manufacturing, assembling, mail treatment, gate control system and identification.But for prior art, rfid interrogator often needs to be connected with computing machine by RS232, USB or Ethernet interface, could realize the read-write to it, thereby be not easy to carry, then price is relatively high for special-purpose handhold RFID read write line, thereby is unfavorable for the widespread use of RFID technology.
The utility model content
For overcoming above the deficiencies in the prior art, the technical problems to be solved in the utility model provides and a kind ofly is easy to carry, lower-cost for the rfid interrogator on the mobile phone, thereby is conducive to extensive popularization and the application of RFID technology.
The technical solution of the utility model is:
A kind of for the rfid interrogator on the mobile phone, comprise the rfid interrogator chip, be used for to transmit antenna and the microcontroller of radiofrequency signal, wherein antenna is connected with the rfid interrogator chip, the rfid interrogator chip is connected with microcontroller again, microcontroller communicates by the microprocessor of communication interface and mobile phone, and microcontroller and rfid interrogator integrated chip are powered on the same printed circuit board (PCB) and by battery of mobile phone.
Above-mentioned for the rfid interrogator on the mobile phone, rfid interrogator chip wherein is the ultrahigh frequency radio frequency identification (RFID) reader chip.
Above-mentioned for the rfid interrogator on the mobile phone, wherein the communication interface between microcontroller and the mobile phone is USB interface.
Above-mentioned for the rfid interrogator on the mobile phone, wherein the communication interface between microcontroller and the mobile phone is blue tooth interface.
The beneficial effects of the utility model are: by rfid interrogator being used or being embedded in the mobile phone, so that mobile phone has possessed the function of read-write RFID label, not only be easy to carry, and compare with the hand-held RFID read-write device of special use, cost is lower; And simultaneously because the RFID technology is mutually integrated with the mobile phone of day by day popularizing, thereby more be conducive to extensive popularization and the application of RFID technology.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the structural principle block diagram for the rfid interrogator on the mobile phone.
Embodiment
As shown in Figure 1, the rfid interrogator that is used on the mobile phone comprises the rfid interrogator chip, be used for transmitting antenna and the microcontroller of radiofrequency signal, wherein antenna is connected with the rfid interrogator chip, the rfid interrogator chip is connected with microcontroller again, microcontroller communicates by the microprocessor of communication interface and mobile phone, and microcontroller and rfid interrogator integrated chip are powered on the same printed circuit board (PCB) and by battery of mobile phone.Like this, by rfid interrogator being used or being embedded in the mobile phone, just so that mobile phone has possessed the function of read-write RFID label, not only be easy to carry, and compare with the hand-held RFID read-write device of special use, cost is lower, and simultaneously because the RFID technology is mutually integrated with the mobile phone of day by day popularizing, thereby more be conducive to extensive popularization and the application of RFID technology.
As a kind of preferred, the rfid interrogator chip may be selected to be the ultrahigh frequency radio frequency identification (RFID) reader chip, and the communication interface between microcontroller and the cell-phone microprocessor can be USB interface or blue tooth interface.Certainly, also can adopt other rfid interrogator chip and/or communication interface.
The above has done detailed description to the preferred embodiment of the utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken that those skilled in the art possess, can also make without departing from the concept of the premise utility various variations.
