The utility model belongs to the RFID technical field and relates to a WiFi and RFID signal repeater. The WiFi and RFID signal repeater includes an RFID reader-writer which reads and writes information of RFID tags, a central processing unit which is connected with the RFID reader-writer and processes the data of the RFID tags, and a WiFi communication device which is connected with the central processing unit and a WiFi network. With the WiFi and RFID signal repeater of the utility model adopted, direct communication between the active RFID tag reader-writer and the WiFi network can be realized; remote network reading and writing of the RFID tags can be realized; RFID-communication wireless network access can be realized; the situations of short RFID communication distance and complicated laying of wired equipment can be eliminated; the difficulty in the laying of network communication between the RFID reader-writer and a server can be lowered; construction and maintenance cost can reduced; and the flexibility of a system can be improved.
Description
Technical field
The utility model relates to the RFID technical field, particularly a kind of read-write capability and WIFI network insertion that possesses 2.4G hertz RFID label simultaneously.
Background technology
In recent years, along with the continuous development of the communication technology, RFID used and to have obtained the development of advancing by leaps and bounds.RFID solve short haul connection scene effect very significantly, as fields such as personnel's article location, electronic shelf label, all-purpose card consume system, ETC Fare Collection System, personnel's work attendance, campus Electronic school badges.RFID with its low power consumption and low cost, lay effective etc. the advantage of convenient, sign and in above numerous areas, obtained approval widely.
But the communication distance of RFID technology is generally all shorter, the RFID communication pattern of active 2.4GHZ at last just, and communication distance also has only over one hundred rice farthest.
Therefore, the RFID technical field needs a kind of equipment to solve the short problem of communication distance.
Summary of the invention
The utility model provides a kind of wireless WIFI transmission network that relies at the too short problem of communication distance that exists in the existing RFID technology, realizes the far Distance RFID application.The technical scheme that the utility model adopts is as follows:
WIFI and RFID signal repeater is characterized in that, comprise:
Rfid interrogator carries out reading and writing of information to the RFID label;
Central processing unit connects this rfid interrogator, and the data of this RFID label are handled;
The WIFI communication equipment connects this central processing unit and WIFI network.
As above WIFI and RFID signal repeater, wherein, this rfid interrogator is the microwave read write line of 2.4G hertz.
As above WIFI and RFID signal repeater, wherein, this rfid interrogator is the low frequency rfid interrogator.
As above WIFI and RFID signal repeater, wherein, this rfid interrogator is the high frequency rfid interrogator.
As above WIFI and RFID signal repeater, wherein, this rfid interrogator is ultrahigh frequency radio frequency identification (RFID) reader.
The utility model has been realized the direct communication of active RFID tag read write line and WIFI network, realized the telecommunication network read-write of RFID label, the wireless network of having realized RFID communication inserts, overcome existing RFID communication distance weak point and the loaded down with trivial details situation of wireline equipment laying, reduced the laying difficulty of network service between rfid interrogator and the server, reduce construction and maintenance cost, improved the flexibility of system.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is structure chart of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, be structure chart of the present utility model, the utility model comprises:
Rfid interrogator 2 carries out reading and writing of information to RFID label 1; Rfid interrogator 2 can be the microwave read write line of 2.4G hertz, and perhaps the rfid interrogator of low frequency, high frequency, hyperfrequency all can;
Central processing unit (CPU) 3 connects rfid interrogator 2, and the data of RFID label 1 are handled;
WIFI communication equipment 4 connects CPU3 and WIFI network 5, and the two-way communication of the data of RFID label 1 is provided for the application that connects into WIFI network 5.
Use the utility model, the process operation principle of reading is: find RFID label 1 by rfid interrogator 2, connect, read the data in the RFID label 1, data are sent to CPU3 handle, CPU3 is according to setting the conversion data form, data are sent to WIFI communication equipment 4, insert the WIFI network by WIFI communication equipment 4, according to setting the IP address data are sent to server, finish data read.
The operation principle of ablation process is: the startup of application server end writes requirement, in database, seek the position that writes target labels, the utility model WIFI and RFID signal repeater under the lock onto target label, set up data communication with the WIFI communication equipment 4 of corresponding WIFI and RFID signal repeater, transmission writes information to the WIFI communication equipment 4 of corresponding repeater, WIFI communication equipment 4 sends to CPU3 with data again, CPU3 changes into corresponding data format with data, data are sent to rfid interrogator 2, rfid interrogator 2 connects with RFID label 1, write data, the data of finishing label write.
The utility model can use one or more WIFI and RFID signal repeater in use in real system, each repeater has the coverage of oneself, and each repeater is is only read and write control to the label in the own coverage.The WIFI network coverage is to insert AP equipment and the realization of rear end route-exchanging device by WIFI.
Repeater of the present utility model is exactly a trunking realizing that RFID label, rfid interrogator and back-end server carry out intercommunication by the WIFI wireless network.Can realize by this signal trunking that rfid system can be finished rapidly flexibly in wireless WIFI network environment and build, reduce the flexibility that construction and maintenance cost, raising system use and adjust, overcome the too short defective of RFID communication distance.
In the RFID of prior art used, communication distance was short, and if adopt wired mode to communicate by letter, the complexity of will the raising system laying reduces the flexibility of system configuration, adjust and the cost of newly-increased read-write equipment all than higher.
The utility model has been realized the direct communication of active RFID tag read write line and WIFI network, realized the telecommunication network read-write of RFID label, the wireless network of having realized RFID communication inserts, overcome existing RFID communication distance weak point and the loaded down with trivial details situation of wireline equipment laying, reduced the laying difficulty of network service between rfid interrogator and the server, reduce construction and maintenance cost, improved the flexibility of system.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
