Background technology
Modern data management application is a large amount of to adopt various coding file modes, in various storage mediums or be recorded in the document, utilizes computer technology to retrieve the various data storage of correspondence coding, makes the complicated work that searches become than being easier to.Coding read and discern read methods such as common employing bar code, magnetic card, IC-card and noctovisor scan, transfer corresponding pre-deposit data after the machine computing identification as calculated, the shortcoming of the method is that bar code pollutes and damage easily, cause the difficulty that reads and discern, and the magnetic card of contact-type, IC-card are can be because of mechanical wear, loose contact etc. former thereby can't reading of data.Thereby a kind of semi-conductor chip (RFID chip) of the special record coding by the radio wave transmissions data appearred, it is written in the various cards that need data identification every field can be be widely used in.But, read this chip data and need special fetch equipment, the general volume of this equipment is bigger, be not easy to carry, it is just inconvenient to read under main equipment and the industry spot mal-condition chip data on the working equipment, and the less hand-held of volume is read the cost of decoding apparatus than higher, can't satisfy the request for utilization of various enterprises.
In sum, RFID chip fetch equipment of the prior art exists volume big, not portable, shortcomings such as the scope of application is little, price height.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of volume little, easy to carry, applied widely, cheap less radio-frequency data card data fetch device.
The technical scheme that the utility model adopted is: the utility model comprises the shell of a card shape circuit board and the described card shape circuit board of encapsulation, on the described card shape circuit board CF card terminal is installed, the CF card controller, CPU, serial communication controller, the serial communication interface terminal, electric pressure converter, the RFID controller, coil, the serial communication interface terminal, one end of described card shape circuit board and described CF card terminal are adaptive, described CF card terminal is installed on this end termination, and the CF interface on described CF card terminal and Hand Personal Computer or the portable computer is pegged graft adaptive.
Described coil can be an air core coil, also can be the coil that has magnetic core.
Described coil is in an end of described card shape circuit board, and the plane of described coil axle center face and described card shape circuit board is perpendicular.
The invention has the beneficial effects as follows: the utility model is owing to comprise the shell of a card shape circuit board and the described card shape circuit board of encapsulation, on the described card shape circuit board CF card terminal is installed, the CF card controller, CPU, serial communication controller, electric pressure converter, coil, the RFID controller, the serial communication interface terminal, described CF card terminal with can realize reading after the digital device with CF interface standard is connected to storage data on the RFID chip, become a portable chip data fetch equipment, so it is little to have volume, easy to carry, applied widely, cheap advantage is a kind of compact apparatus of RFID chip data read easy to use.

Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, this practicality newly comprises the shell 2 of a card shape circuit board 1 and the described card shape circuit board 1 of encapsulation, on the described card shape circuit board 1 CF card terminal 3, CF card controller 4, CPU 5, serial communication controller 6, electric pressure converter 7, RFID controller 8, coil 9, serial communication interface terminal is installed.One end of described card shape circuit board 1 and described CF card terminal 3 are adaptive, and described CF card terminal 3 is installed on this end termination, and described CF card terminal 3 is pegged graft adaptive with the CF interface on the PDA.Described CF card terminal 3 with can realize that the reading of storage data on the RFID chip become a portable RF ID chip data fetch equipment after the digital device with CF interface standard is connected.
The RFID chip can be the commercially available less radio-frequency data card that has telefault passive resonance loop.
The process that reads of RFID chip data: by finishing read operation by radiowave between the coil in non-contacting RFID chip and the described less radio-frequency data read card to RFID chip data.The RFID chip itself is passive body, i.e. itself not charged source, the passive resonance in parallel loop that the supply of power supply is made up of telefault, capacitor provides, simultaneously the telefault on the RFID chip also as with the data-interface of less radio-frequency data read cartoon letters.When less radio-frequency data read card reads the RFID chip, coil emitting radio wave on the less radio-frequency data read card, generate an electromagnetic field by the passive resonance loop on the RFID chip, the RFID chip obtains the moment electric energy by the passive resonance loop of parallel connection from electromagnetic field, the coding chip in the RFID chip will stick into the line data exchange with the less radio-frequency data read at this moment.
CF interface communication process: the CPU in the less radio-frequency data read card reads the RFID chip data that transmitted by the RFID controller, be transferred to CF cartoon letters terminal by the CF card controller, give handheld computer or the pocket computer adaptive data transmission by CF cartoon letters terminal, use the data of the RFID chip that is obtained by the application software in the computing machine with it.
Described coil 9 can be used the exoskeletal air core coil of enameled wire coiled, and described coil 9 is in an end of described card shape circuit board 1, and the plane of described coil 9 axle center faces and described card shape circuit board 1 is perpendicular.The nearly RFID chip of a termination that described card shape circuit board 1 has coil 9 is finished non-contact data and is read.
The shape and size of described shell 2 one ends keep being connected firmly stable after can make the CF card on described CF card terminal 3 and the PDA peg graft.The shape and size of the other end of described shell 2 can make coil 9 be included in its inside.
This less radio-frequency data read cartoon is crossed the CF card slot that inserts PDA and is subjected to electricity and startup work, for PDA, this less radio-frequency data read card is exactly a peripherals, and the application software of the last operation of PDA can be carried out operating functions such as ON/OFF, transmission/reception data, setting data form to this less radio-frequency data read card.CF card controller 4 can adopt the OXCF950B chip to realize that the CF interface conversion is the function of UART communication.Behind the OXCF950B electrification reset, configuration virtual serial ports on PDA.CPU receives the data acquisition that yard steering order removes to control RFID controller 8 of adopting that PDA sends, and data of gathering are passed to CF card controller 4 by the UART communication mode, and CF card controller 4 is passed to PDA by the CF interface standard again.RFID controller 8 can adopt the EM4095 chip to realize that by coil 9 concussions less radio-frequency reads RFID chip data.Electric pressure converter 7 realizes that PDA 3.3V voltage changes 5V, offers the EM4095 chip operation.Simultaneously, serial communication controller 6 can adopt MAX3232 chip expansion RS232 serial communication interface, is with the equipment of RS232 interface to carry out communication with other.
Simultaneously, because less radio-frequency data read card is from the PDA power taking, so adopt the low-power consumption components and parts.
Each circuit unit can adopt general electron device in the utility model.
