Description
Technical field
The utility model relates to card reader technical field, particularly a kind of portable RFID card reader based on blue tooth interface and attendance checking system.
Background technology
RFID is the english abbreviation of radio-frequency (RF) identification.Generally, RFID card reader is a kind of automatic identification equipment of energy read electronic label data.RFID radio-frequency (RF) identification is a kind of contactless automatic identification technology, and it automatically identifies destination object by radiofrequency signal and obtains related data, and the work of identification need not manual intervention, can work in various rugged surroundings.RFID technique identifiable design high-speed moving object also can identify multiple label simultaneously, swift and convenient to operate.In all RFID products, the gold content of RFID card reader is the highest, because it is the set of the multiple technologies such as semiconductor technology, radio-frequency technique, high-efficiency decoding algorithm.The product now emerged mostly is produced by American-European-Japanese company, and domestic corporation also rarely has product to come out.So will grasp at the opportunity that this is huge, domestic manufacturer has got long long way to go.
RFID card reader volume is in the market comparatively large, and use trouble to domestic consumer, price is higher, and portability is poor.
Utility model content
The utility model, for prior art above shortcomings, provides a kind of portable RFID card reader based on blue tooth interface.The utility model is achieved through the following technical solutions:
Based on a portable RFID card reader for blue tooth interface, comprising:
Main control unit, and the bluetooth module, key-press module, display module and the RFID module that are connected with main control unit respectively;
Wherein, main control unit comprises MCU single-chip microcomputer, is connected with RFID module by serial communication mode; Main control unit, bluetooth module, key-press module, display module and RFID module are all integrated on one piece of circuit board.
Preferably, MCU single-chip microcomputer comprises the MCU single-chip microcomputer based on STC15W404AS model.
Preferably, display module comprises 1602 LCD MODULE.
The utility model separately provides a kind of attendance checking system, comprises following technical scheme:
A kind of attendance checking system, comprises the above-mentioned portable RFID card reader based on blue tooth interface and some rfid cards.
Compared with prior art, the utility model has following beneficial effect:
(1) the portable RFID card reader based on blue tooth interface that provides of the utility model, can reduce energy consumption further, and is conducive to reducing the cost building rfid system;
(2) circuit board that the utility model provides adopts expansion interface to connect computer equipment, enhances the versatility of platform, has higher extensibility;
(3) card reader can support multiple different computing equipment, is conducive to the application improving platform.
Accompanying drawing explanation
Shown in Fig. 1 is the system architecture schematic diagram of the utility model embodiment;
Shown in Fig. 2 is the bluetooth module block diagram that the utility model provides.
Embodiment
Below with reference to accompanying drawing of the present utility model; clear, complete description and discussion are carried out to the technical scheme in the utility model embodiment; obviously; as described herein is only a part of example of the present utility model; it is not whole examples; based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to protection domain of the present utility model.
For the ease of the understanding to the utility model embodiment, be further explained for specific embodiment below in conjunction with accompanying drawing, and each embodiment does not form the restriction to the utility model embodiment.
As shown in Figure 1, a kind of portable RFID card reader 1 based on blue tooth interface that the utility model provides, comprising: main control unit 11, and the key-press module 15, display module 14, bluetooth module 12 and the RFID module 13 that are connected with main control unit 11 respectively; Main control unit 11 comprises MCU single-chip microcomputer, is connected with RFID module 13 by serial communication mode; Main control unit 11, key-press module 15, display module 14, blue tooth interface 12 and RFID module 13 are all integrated on one piece of circuit board.
In the present embodiment, display module 14 adopt model be 1602 low cost LCD MODULE, but to be not limited thereto, can according to other dissimilar integrated chips of required selection.
This enforcement provide the using method of system and principle of work as follows:
Generally, RFID module 13 carries out data acquisition by the cycle of presetting, and by the ID data collected by sending to main control unit 11.ID data are stored in the storage space of self by main control unit 11; Meanwhile, main control unit 11 pairs of ID data analysis.The data that RFID device collects are undertaken showing, process and being transmitted by blue tooth interface by single-chip microcomputer.
As shown in Figure 2, bluetooth module 12 comprises Bluetooth chip BCM20730, and connected EEPROM, UART interface, GPIO interface and Bluetooth antenna.
In concrete application, can using the utility model as attendance checking system.Such as, in the work attendance of classroom, teacher is read the rfid card entrained by the student in classroom by the portable RFID card reader based on blue tooth interface, without the need to losing time on roll-call is registered successively, RFID card reader disposablely can identify the multiple rfid cards in scope and read, and has saved the attendance record time.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
