Abstract
The utility model discloses a universal serial bus (USB) radio-frequency card reader free of drive in the field of radio-frequency card reading. The USB radio-frequency card reader comprises a micro controller, wherein the micro controller is connected with a personal computer (PC) through a USB interface module, and the micro controller is also connected with a card through a radio-frequency read-write model. Accordingly, special drive cannot be arranged during usage, a USB interface and the PC can complete communication, then the play-and-plug function can be achieved, the usage is facilitated, and the radio-frequency card reader can be used in data exchange of various types of radio-frequency cards.
Description
Technical field
The utility model relates to a kind of radio frequency card-reading apparatus, particularly a kind of USB radio-frequency card reader.
Background technology
Existing in the market various radio-frequency card readers; General radio-frequency card reader is communicated by letter with PC through the USB interface form; Yet when normal the use, need on PC, to install special-purpose driving; Cooperate the application program of client layer normally to use, this just makes complicated more in use loaded down with trivial details.
The utility model content
The purpose of the utility model provides the moving radio-frequency card reader of a kind of USB free drive, has removed from special-purpose driving process is installed on PC, makes that use is convenient.
The purpose of the utility model is achieved in that a kind of USB free drive moves radio-frequency card reader, comprises the microcontroller that links to each other with PC through usb interface module, and said microcontroller also links to each other with card through the radio frequency module for reading and writing.
As the improvement of the utility model, said microcontroller adopts STM32 F101C6T6 chip.
As the improvement of the utility model, said radio frequency module for reading and writing adopts the MFRC522 chip, and said MFRC522 chip is accomplished exchanges data through antenna and card.
During the utility model work, this device is connected on the PC through USB interface, PC sends signal through the control microcontroller and gives the radio frequency module for reading and writing, makes radio frequency module for reading and writing and card carry out exchanges data.Compared with prior art; The beneficial effect of the utility model is: the utility model is realized accomplishing exchanges data between PC and the card through the mode of STM32 F101C6T6 chip and MFRC522 chip portfolio; Avoid on PC, installing special-purpose the driving; Realize plug and play, make when using this device convenient.The utility model can be used in all kinds of radio-frequency card exchanges data.
Description of drawings
Fig. 1 is the utility model control principle block diagram.
Fig. 2 is the utility model circuit theory diagrams.
Embodiment
A kind of USB free drive shown in Fig. 1-2 moves radio-frequency card reader; Comprise the microcontroller that links to each other with PC through usb interface module; Said microcontroller also links to each other with card through the radio frequency module for reading and writing; Microcontroller adopts STM32 F101C6T6 chip, and said radio frequency module for reading and writing adopts the MFRC522 chip, and said MFRC522 chip is accomplished exchanges data through antenna and card.
This device is connected on the PC through USB interface; PC sends signal through control STM32 F101C6T6 chip and gives the MFRC522 chip; Make MFRC522 chip and card carry out exchanges data, in the use, need not on PC, to install special-purpose the driving; In the equipment manager of PC,, cooperate the application program of client layer can accomplish current again with the HID devices communicating.
The utility model is not limited to the foregoing description; On the basis of the disclosed technical scheme of the utility model; Those skilled in the art is according to disclosed technology contents; Do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the protection domain of the utility model.
