Abstract
The invention provides a Bluetooth RFID reader writer which integrates RFID and Bluetooth technique together. A processor is connected with a Bluetooth module and a RFID module by an address data bus, thus the data red and written by the RFID module is transferred into the Bluetooth module and the Bluetooth module is communicated with the Bluetooth device by the wireless way to store and manage the data of the reader writer. The RFID module reads the data from the label through the radio frequency signal. The connection of the RFID module with the RFID radio frequency network is controlled by the AT command in the reader writer, then the RFID module is connected with a server by PPP protocol; when the Bluetooth device wants to access, the Bluetooth device inquires about the SPP service information of the Bluetooth RFID reader writer by the SDP service and is connected with the SPP service of the Bluetooth RFID reader by a connection base band, L2CAP, RFCOMM protocol, then is connected with the Bluetooth RFID reader writer by the PPP protocol; after connection, the Bluetooth RFID reader writer takes charge of performing the address conversion of the TCP/IP data from the PPP protocol by the server and sending out the conversed data from the Bluetooth end.
Description
Technical field
The present invention relates to the communications field, relate in particular to Bluetooth wireless technology and RFID REID.
Background technology
Bluetooth (Bluetooth) is a kind of emerging short distance radio communication standards, is a kind of small-sized, economic, the short-range Radio Link of setting up between portable computer, mobile phone and other mobile device.The frequency range of this regulation and stipulation work is public ISM band, and peak data rate can reach 3Mbps.Utilize the equipment of Bluetooth technology communication to spread all trades and professions at present, as mobile phone, notebook, PDA, digital camera etc.These equipment are by Bluetooth technology wirelessly transmitting data easily.
RFID (Radio Frequency Identification) radio-frequency (RF) identification is a kind of contactless automatic identification technology, it is by the automatic recognition objective object of radiofrequency signal and obtain related data, 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.
Bluetooth RFID reader writer, RFID is combined with Bluetooth technology, the data of RFID read-write will be by Bluetooth transmission on wireless handheld PDA, smart mobile phone, computer, and then from the terminals such as mobile phone by 3G network with data transmission to remote server, greatly make things convenient for the storage and the management of data, be fit to very much the use of every field such as logistics and supplies management, mail package processing, document management, animal identification sign, electronic entrance ticket and mobile office.RFID is 2 kinds of different technology with bluetooth, and how it being combined promptly is that the present invention is with the problem that solves.
Summary of the invention
The present invention will provide a kind of Bluetooth RFID reader writer that RFID and Bluetooth technology are integrated.The object of the present invention is achieved like this:
As Fig. 1, Bluetooth RFID reader writer is characterized in that hardware comprises processor (3).Processor (3) is the control core of Bluetooth RFID reader writer, and processor (3) links to each other with bluetooth module (1) by serial ports, and bluetooth module (1) links to each other with antenna (7) by radio frequency interface, and antenna (7) is used for the transmitting/receiving wireless signal.RAM (8) links to each other with processor (3) by address data bus, and Flash (4) links to each other with processor (3) by address data bus, is used for storing data information.The other end of processor (3) links to each other with RFID module (2) by address data bus, RFID module (2) by radiofrequency signal from label (6) reading writing information.Bluetooth module (1) passes through the wireless mode communication with bluetooth equipment (5), is used for the information of read-write is stored and managed.
Bluetooth RFID reader writer also has another kind of implementation, and is basic identical with Fig. 1 as shown in Figure 2, and unique difference is inner integrated processor (3), Flash (4), RAM (8) and an antenna (7) of bluetooth module (1).
Bluetooth RFID reader writer protocol model figure as shown in Figure 3, when bluetooth equipment (11) needs control Bluetooth RFID reader writer (12), bluetooth equipment (11) is by the SPP information on services of SDP service-seeking Bluetooth RFID reader writer (12), be connected to the SPP service of Bluetooth RFID reader writer (12) then by connection base band, L2CAP, RFCOMM agreement, in the SPP service, by our self-defining function, RFID controller in the control Bluetooth RFID reader writer (12) allows it produce signal and reads and writes RFID label (10).
The rfid interrogator read-write capability is achieved as follows:
1) interface initialization: the initialization of label interface unit, the interface energising is opened, and RF opens in the zone.
2) seek label: in the RF territory, seek a label, return the UID of label.
3) reading and writing data: read a data block from the user data area of label; Or data block is write into the user data area of label.
4) latch: with the specified data block permanent locking that writes, this data block will become a read states.
5) down interface: the label interface unit is closed, and the interface power supply will be closed.
