[0028] Among them, except that the second voice processing unit in the receiving end is different from the first voice processing unit in the explanation host end and the explanation auxiliary end, the remaining modules are the same as those in the explanation host end and the explanation auxiliary end.

The chip U2 adopts the Beidou module, and the Beidou module is connected to the processing chip U1 through the serial port TXD / RXD. The Beidou positioning unit adopts the Beidou module and its peripheral circuits to perform outdoor positioning of the user. The Beidou module and its peripheral circuits collect and analyze the location information, and transmit it to the processor through the serial port. The processor transmits the signal to the signal processing unit for amplification processing, and then the signal transceiver unit transmits it to the background, and the background can know the user's location.

[0035] The RFID unit is connected to the processor through the SPI interface, and is used for positioning in large indoor environments without Beidou signals. In specific settings, an RFID reader is installed indoors.

[0038] Specifically, the structure of the indicator light unit is as follows: Figure 5As shown, it is used to display the working status of the wireless lecturer. For example, during the communication connection between the wireless lecturer and the terminal, the D1 light keeps flashing, and the D2 and D3 lights are off; when the connection is normal, D1 stops flashing and remains on, and the D2 and D3 lights continue to remain off; when the connection is abnormal, D3 keeps flashing, prompting the user that the communication connection between the wireless lecturer and the terminal has failed, and the D1 and D2 lights remain off; when the wireless lecturer and the terminal are connected normally and data is transmitted, the D2 light starts to flash continuously, and when the data transmission is completed, D2 stops lighting, and the D1 and D3 lights remain off.
