Background technology
RFID (Radio Frequency Identification, radio-frequency (RF) identification) technology is a kind of automatic identification technology that begins to rise the nineties in 20th century, it is that a kind of radiofrequency signal of utilizing realizes the transmission of non-contact type information by space coupling (alternating magnetic field or electromagnetic field), and the information of passing through to be transmitted reaches the technology of automatic identifying purpose.Non-visual transmission, transmission speed are fast because this technology has, penetrability more by force, stronger anti-adverse environment ability and advantage such as reusable and extremely numerous industries and professional person's concern.Make a general survey of domestic and international rfid system, its basic comprising is RFID tag, radio-frequency identification reader and application layer software; Wherein the function of radio-frequency identification reader is to receive the command information of application layer, startup radio-frequency module wherein is with control antenna work, finish and the communicating by letter of radio-frequency (RF) tag, simultaneously the label information that recognizes is transferred to application layer for customer analysis and processing by communication interface.
Aforementioned existing RFID reader majority has only single communication interface; The RFID reader all is the controlled device as application layer, only the retrieval of responsible label information and transmission; Independent fully between reader and the reader, interconnected flexibly between this just very difficult reader of realizing in the radio frequency network.In addition, also can't realize being connected with the flexible of multiple memory device and industrial field device.
Summary of the invention
The technical matters that the utility model solves is to provide a kind of and can overcomes aforementioned technical problem, has the multiple interfaces form, can with equipment such as PDA (Personal Digital Assistant, personal digital assistant), smart mobile phone, removable computer and PC between carry out information transmission; Also can be with forming the radio-frequency (RF) identification network between a plurality of readers, to realize the RFID reader of the collaborative work between reader and the reader.
The technical matters that the utility model solves is achieved by the following technical solution: mainly include power supply, interface control module, CPU, RF module, antenna and memory module; Power supply is given RF module, interface control module, memory module and CPU power supply; Antenna and label carry out the transmission of energy and information, and label information are transferred to by the RF module in time CPU carries out analyzing and processing and memory module is stored; Described interface control module comprises multiple interfaces such as network interface, CF interface, USB interface, Wiegand26 interface and RS-232.
The network interface of described interface control module be between data interaction between reader and application layer and the reader networking to realize the interface of collaborative work between reader.

Description of drawings
Accompanying drawing is the utility model reader structured flowchart.
The explanation of accompanying drawing figure number:
Heartbeat line 17
Embodiment
See accompanying drawing, reader of the present utility model mainly includes power supply 11, interface control module 12, CPU13, RF module 14 (radio frequency identification module), antenna 15 and memory module 16; Power supply 11 is given RF module 14, interface control module 12, memory module 14 and CPU 13 power supplies; This power supply 11 adopts rechargeable lithium battery, with guarantee this reader can be under the situation that mains-supplied is interrupted also can operate as normal a period of time; Antenna 15 carries out the transmission of energy and information with label, and label information is transferred to by RF module 14 in time CPU 15 carries out analyzing and processing and memory module 16 is stored; Described interface control module 12 has adopted the standby form of multiple interfaces, mainly comprises multiple interfaces such as network interface, CF interface, USB interface, Wiegand26 interface and RS-232.
Network interface in the aforementioned interface control module 12 makes this reader to link to each other with application layer easily, and can carry out networking with application layer or other reader, to realize the collaborative work function between network-type radio-frequency (RF) identification and reader; And the CF interface is mainly used in PDA, smart mobile phone and removable computer and communicates operation, and USB, Wiegand26 interface and RS-232 interface mainly realization and memory device, PC and industrial field device communicate function.
In collaborative work, the collaborative work module of the software section of reader realizes data transmission and cross complaint operation between the reader based on complete communication protocol.For example: at first, reader A sends message request to reader B, if reader B accepts request, reader B will send response message and make Message Processing to reader A, otherwise reader A continues to send out request message to reader B, till reader B receives request.
Because radio-frequency (RF) identification speed is very fast, quantity of information is more, is the coordinations at different levels of realization system, and this reader CPU13 can adopt high-speed controller, as ARM, PowerPC and Godson series microprocessor etc.; Radio frequency identification module 14 adopts integrated microcontroller and RF transmit-receive circuit in the tag recognition module of one, communicates with peripheral antenna 15, thereby realizes the identification of radio-frequency (RF) tag ground, comprising element circuits such as modulation, encoding and decodings.And memory module 16 is divided into the storage of non-memory property and two modules of Memorability storage, and the former is used for storing the label ID information that radio frequency identification module recognizes, and deposits in the Memorability module through the information after the processing such as data filter and integration.
RFID reader of the present utility model also can comprise heartbeat line 17, and this heartbeat line 17 is used for transmitting heartbeat message between the main and auxiliary reader, and auxilliary reader is by monitoring and analysis to heartbeat message, and just whether decidable master reader breaks down.
