Abstract
The utility model discloses a mobile phone plug-in RFID (radio frequency identification) reader-writer based on bluetooth communication, which comprises a shell. The RFID reader-writer is characterized in that: a singlechip with a USB (universal serial bus) controller is arranged in the shell; the singlechip is respectively connected with a lithium battery, an erasable memory, a USB communication interface, an RFID read-write chip and a bluetooth communication module; and the RFID read-write chip is connected with an antenna. The whole reader-writer disclosed by the utility model is plugged on the back of an smart mobile phone, and paired with the smart mobile phone through bluetooth communication, the RFID reader-writer can be used for reading and writing an RFID read-write chip by receiving corresponding commands and data, and whether the operation result is successful or not is sent to the smart mobile phone.
Description
Technical field
The utility model relates to the equipment in a kind of telecommunications field, specifically, relates to a kind of mobile phone external hanging type rfid interrogator based on bluetooth communication.
Background technology
RFID is a kind of non-contact data mechanics of communication, is applicable to association areas such as civilian payment, gate control system, Courier Service.Because being subject to rfid interrogator is connected with the physical communication of host computer, causes rfid interrogator portable performance difference to limit its application in portable circulation industry.Along with the development of 3G technology, the performance of smart mobile phone and application function are progressively powerful, and smart mobile phone can become the host computer of rfid interrogator fully, thereby realize the plug-in rfid interrogator of smart mobile phone, realize portable use through the wireless blue tooth communication.
The utility model content
The technical matters that the present technique scheme will solve provides a kind of mobile phone external hanging type rfid interrogator based on bluetooth communication.
The present technique scheme adopts following technological means to realize goal of the invention:
A kind of mobile phone external hanging type rfid interrogator based on bluetooth communication; Comprise shell; It is characterized in that: be provided with the single-chip microcomputer that has the USB controller in the said shell; Said single-chip microcomputer connects lithium battery, erasable memory, USB communication interface, RFID read-write chip and bluetooth communication module respectively, and said RFID read-write chip connects antenna.
Compared with prior art; The advantage and the good effect of the utility model are: the whole read write line of the utility model hangs over the smart mobile phone back outward; Be connected with the smart mobile phone pairing through bluetooth communication, smart mobile phone sends order and data as the host computer of external hanging type rfid interrogator through bluetooth communication module; Rfid interrogator receives corresponding order and data are carried out read-write operation to the RFID read-write chip, and whether operating result is successfully sent to smart mobile phone.
Description of drawings
Fig. 1 is the functional-block diagram of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is made detailed description further.
Referring to Fig. 1; The utility model comprises shell, single-chip microcomputer, lithium battery, erasable memory, USB communication interface, RFID read-write chip, bluetooth communication module, antenna; Be provided with the single-chip microcomputer that has the USB controller in the said shell; Said single-chip microcomputer connects lithium battery, erasable memory, USB communication interface, RFID read-write chip and bluetooth communication module respectively, and said RFID read-write chip connects antenna.
Enclosure contains RFID read-write chip and antenna, under the control of single-chip microcomputer, can read and write standard agreement RFID electronic tags such as meeting HF frequency range ISO15693/ISO18000-3.
Based on bluetooth communication module, the data upload that both can the RFID read-write chip have been read is in mobile phone; Also can the data in the mobile phone be downloaded in the RFID read-write chip,, increase the security of system through the hardware net address realization external hanging type rfid interrogator of storage smart mobile phone bluetooth module and the hardware binding of smart mobile phone.
Equipment DC3.7V, 1500mAh lithium ion polymer chargeable battery is avoided consuming battery of mobile phone and is caused stand-by time short, can give lithium cell charging through built-in USB communication interface.
Whole read write line hangs over the smart mobile phone back outward; Be connected with the smart mobile phone pairing through bluetooth communication; Smart mobile phone is as the host computer of external hanging type rfid interrogator; Send order and data through bluetooth communication, rfid interrogator receives corresponding order and data are carried out read-write operation to the RFID read-write chip, and whether operating result is successfully sent to smart mobile phone.
Mobile phone external hanging type rfid interrogator configures after bluetooth successfully matches first; The bluetooth controller hardware net address (MAC Address) of mobile phone is stored in the erasable memory; Bluetooth pairing will check whether the bluetooth controller hardware net address of mobile phone is consistent with address stored next time; Thereby realize the hardware binding of external hanging type rfid interrogator and smart mobile phone, increase the security of system.
