Drawings
Fig. 1 is a schematic diagram of a two-in-one electronic tag card reader according to an embodiment of the present invention.
In the figure, the serial numbers are 1, MCU 2, power module 3, RFID read-write module 4, ID card read-write module 5, active label read-write module 6, communication interface module 7 and wireless transceiver.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the two-in-one electronic tag card reader includes an MCU 1 and a power module 2, the MCU 1 is further connected to an RFID read/write module 3 (e.g., an IBAT2000RFID read/write chip), an ID card read/write module 4 (e.g., a BRF7941 read/write module) and an active tag read/write module 5, and a communication interface module 6.
In a preferred embodiment, the active tag read/write module 5 is connected with a wireless transceiver 7, the wireless transceiver can adopt an RF433 wireless transceiver module, and the active tag read/write module can adopt a model of SYC 4439.
Further, the device also comprises a communication interface module, wherein the communication interface module adopts a USART module or an I2C module.
When the RFID read-write module 3 detects the RFID tag, electromagnetic waves are emitted, an electromagnetic field is formed around the RFID tag, the tag obtains energy from the electromagnetic field to activate a microchip circuit in the tag, the chip converts the electromagnetic waves and then sends the electromagnetic waves to the RFID read-write module 3, and the reader converts the electromagnetic waves into related data. The control computer can process the data to perform supervisory control.
The active tag can form an effective active area around the tag by internal power, actively detect whether a calling signal transmitted by a reader exists around, and transmit the information of the active tag to a reader module, namely an active tag read-write module 5.
Therefore, the embodiment of the utility model provides a possess the card reading function of different frequency channel electronic tags cards such as 433M to satisfy various demands under the different occasions.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
