A kind of electronic tag conversion read-write equipment
Technical field
The utility model relates to a kind of radio-frequency (RF) identification fetch equipment, specifically is meant a kind of radio-frequency (RF) identification conversion read-write equipment of realizing the frequency of operation conversion.
Background technology
Title radio-frequency (RF) tag, radio-frequency (RF) identification that radio frequency identification RFID has.It is a kind of contactless automatic identification technology, and by radiofrequency signal recognition objective object and obtain related data, identification work need not manual intervention.Electronic tag is according to the difference of the mode of obtaining electric energy, can be divided into active formula label and passive type label: active formula label is powered by the internal cell that label carries, its electric energy abundance, functional reliability height, the frequency of operation height, the distance that signal transmits.Active formula label can limit the service time or the access times of label by the different life-spans of design battery, and it can be used in needs the restricting data transmission quantity or use the conditional place of data.The shortcoming of active formula label mainly is that price height, volume are big, and be restricted the serviceable life of label, and along with the consumption of battery electric power in the label, the distance of data transmission can be more and more littler, influences the operate as normal of system.The inside of passive type label is charged pool not, needs outer boundary that energy ability operate as normal is provided.The passive type label has the permanent operating period, and usually being used in label information needs read-write every day or frequent read-write place repeatedly, and long data transmission of passive type label support and nonvolatil data storage.The shortcoming of passive type electronic tag mainly is that radio frequency knowledge distance will more active formula electronic tag weak point.But low because of its price, volume is little and ease for use, becomes the main flow of application.The frequency of operation of electronic tag has: 125KHZ, 13.56MHz, 900MHz, 2.45GHz, 5.8GHz.
At present frequency of operation be 13.56MHz electronic tag customer group and use more, technology maturation, but, can't satisfy the needs of remote identification or control because its wireless identification distance can only be 30CM.
The utility model content
The electronic tag that the problem that the utility model need solve provides a kind of identification range with the 13.56MHz frequency transfers the radio-frequency (RF) identification conversion read-write equipment of the electronic tag of bluetooth recognition scope to.
To achieve these goals, the utility model is designed a kind of electronic tag conversion read-write equipment, comprises the read write line that can discern and read the 13.56MHz electronic tag, and described read write line is connected with conversion module, and conversion module connects with bluetooth module.
Described conversion module comprises the data message that can obtain the 13.56MHz electronic tag and is converted to the control chip of the data-signal that bluetooth module can use and the data information memory device of storage 13.56MHz electronic tag.
Described bluetooth module is made up of the chip that is integrated with Bluetooth function.
The information of low-frequency card that the utility model device, read write line read is converted to high-frequency or long-distance transmissions, can realize long-range opening the door, taxi management and production logistics management.
The utlity model has following beneficial effect: 1, can realize the conversion of electronic tag frequency of operation, low frequency (13.56MHz) electronic tag is converted to the scope of bluetooth recognition or control by conversion module, and the scope of bluetooth recognition is 10 meters.2, maximum has been utilized present low frequency (13.56MHz) electronic tag, reaches the card of closely identification is realized remotely-controlled purpose, satisfies the demand of 13.56MHz electronic tag broader applications.3, have low cost, use flexible characteristic.
Description of drawings:
Fig. 1 is the utility model electronic tag conversion read-write equipment structural representation.
Embodiment
For the ease of those skilled in the art's understanding, structural principle of the present utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As shown in Figure 1, a kind of electronic tag conversion read-write equipment comprises the read write line 1 that can discern and read the 13.56MHz electronic tag, and described read write line 1 is connected with conversion module 2, and conversion module 2 connects with bluetooth module 3.
Conversion module 2 comprises the data message that can obtain the 13.56MHz electronic tag and is converted to the control chip 21 of the data-signal that bluetooth module can use and the data information memory device 22 of storage 13.56MHz electronic tag.
Bluetooth module 3 is made up of the chip that is integrated with Bluetooth function.
Read write line 1 is made up of wireless transceiver, antenna, controller and interface circuit etc., can realize hardware circuit by existing components and parts.
The utility model electronic tag conversion read-write equipment can be applicable to intelligent garage or parking lot, and the electronic tag of 13.56MHz (smart card) can be realized opening the door at a distance.
The utility model electronic tag conversion read-write equipment can be realized transportation and communication is carried out control and management, particularly taxi management, the driver of taxi has the electronic tag (smart card) of 13.56MHz, as I.D., the utility model device is installed on the taxi, the traffic administration personnel, as long as hand-held corresponding data acquisition device, just can read the data message on electronic tag (smart card) card of 13.56MHz, the data message that each taxi is put down in writing is different, can realize thus what car who drives, and prevents to overlap the board taxi, can drive a taxi by unauthorized person simultaneously.
The utility model can be realized the production line management and realize remote-controlled operation, on production line, can make things convenient for and write down process information and technological operation information exactly, to workman's job number, time, operation, quality inspection result's record, can realize the trackability of producing fully.Also can avoid hand-written in the production environment, watch the error that information causes.
The utility model also can be realized warehousing management and realize remote-controlled operation, after the electronic tag on goods or the vehicle is through the utility model device, can read the concrete data message of this goods or vehicle on than distant positions, administrative center can understand the situation of cargo location, goods storage in real time, produces and all has very important significance for raising storage efficient, feedback product information, guidance.It has not only increased the number of packages of handling goods in one day, can also supervise all information of goods.
In addition, the utility model electronic tag conversion read-write equipment can also be applied to fields such as burglary protection system for commodities, logistics and supplies management, the manufacturing and assembling, aviation luggage processing, mail/fast freight parcel processing, document tracking/library management, animal identification sign.
