The radio frequency unit in this embodiment is installed in the exhibition hall of the school exhibition hall, and the radio frequency unit is installed in all areas to be explained in the exhibition hall. When visitors enter a school museum, each person distributes an explanation device, when key places need to be explained, the explanation device only needs to be close to the radio frequency unit, the radio frequency unit receives signals and transmits the signals to the control main board unit, and the control main board unit controls the voice playing module to work, so that intelligent explanation can be performed, and selection of a plurality of languages can be performed.

In this embodiment, each radio frequency unit has a corresponding ID number, and after the radio frequency unit is matched with the interpretation device, the signal and its own ID number are transmitted to the control main board unit, and the main board unit matches the ID number with the internal program to generate different electric signals to be transmitted to each pin of the voice playing module, and the voice module calls each corresponding audio of the storage unit to play according to the received different pin signals.

In the present embodiment, the radio frequency unit is RFID-RC 522.

RFID- -RC522 the system is made up of five components, including: transmitter, receiver, microprocessor, antenna, tag. The transmitter, receiver and microprocessor are typically packaged together, also commonly referred to as a Reader, so the industry often divides RFID systems into three major components, a Reader (Reader), an Antenna (Antenna) and a Tag (Tag).

A reader: the main task of the device for reading or reading/writing the electronic tag information is to control the radio frequency module to transmit a reading signal to the tag, receive the response of the tag, decode the object identification information of the tag, and transmit the object identification information together with other related information on the tag to the host for processing.

An antenna: and the transmitting and receiving device transmits data between the tag and the reader.

Electronic tags (or radio frequency tags, transponders): consists of a chip and a built-in antenna. Electronic data in a certain format is stored in the chip and is used as identification information of an object to be identified, and the chip is a real data carrier of a radio frequency identification system. The built-in antenna is used for communicating with the radio frequency antenna.

In this embodiment, the inside of the explanation device is provided with an inductive IC card, and the chip thereof is: philips Mifare 1S50, 8Kbit storage capacity, 16 partitions, two groups of passwords per partition; the working frequency is 13.56 MHz.

The work flow of the radio frequency unit is as follows: the reader sends a radio frequency signal with a certain frequency through a transmitting antenna; when the explaining device enters a working area of the transmitting antenna, induced current is generated, and the radio frequency unit obtains energy to be activated; the radio frequency unit sends out information such as self codes and the like through a built-in sending antenna of the card; the system receiving antenna receives a carrier signal sent from the radio frequency card, the carrier signal is transmitted to the reader through the antenna regulator, and the reader demodulates and decodes the received signal and then sends the demodulated and decoded signal to the background main system for relevant processing; the main system judges the validity of the card according to the logic operation, and performs corresponding processing and control aiming at different settings, and sends out instruction signals to control the action of the actuating mechanism.

After the electronic tag enters the antenna magnetic field, if a special radio frequency signal sent by a reader is received, product information (a passive tag) stored in a chip can be sent out by means of energy obtained by induced current, or a signal with a certain frequency (an active tag) is actively sent out, and the reader reads and decodes the information and sends the information to a central information system for related data processing.
