Description of drawings

FIG. 1 is a schematic diagram of a two-in-one electronic tag reader according to an embodiment of the present invention.

Serial numbers in the figure: 1, MCU, 2, power supply module, 3, RFID read/write module, 4, ID card read/write module, 5, active tag read/write module, 6, communication interface module, 7, wireless transceiver.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

As shown in Figure 1, the two-in-one electronic tag reader includes a MCU 1 and a power supply module 2. The MCU 1 is also connected with an RFID read-write module 3 (such as an IBAT2000RFID read-write chip), an ID card read-write module 4 ( For example, BRF7941 read/write module) and active tag read/write module 5 and communication interface module 6 can be used.

In a preferred embodiment, the active tag reading and writing module 5 is connected with a wireless transceiver 7, and the wireless transceiver can use the RF433 wireless transceiver module, and the active tag reading and writing module can use the SYC4439 model.

Further, a communication interface module is also included, and the communication interface module adopts a USART module or an I2C module.

When the RFID read-write module 3 detects the RFID tag, it emits electromagnetic waves, and an electromagnetic field is formed around it. The tag obtains energy from the electromagnetic field to activate the microchip circuit in the tag, and the chip converts the electromagnetic wave and sends it to the RFID read-write module 3. The reader takes it converted into relevant data. The control calculator can process these data for administrative control.

Active tags can use internal power to form an effective active area around the tag, actively detect whether there is a call signal emitted by the reader around, and transmit its own data information to the reader module, that is, the active tag read-write module 5.

Therefore, the embodiment of the present invention has the card reading function of electronic label cards of different frequency bands such as 433M, so as to meet various demands in different occasions.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the present invention , alternatives and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
