the second terminal (14) is remote equipment and is used for receiving the alarm signal and the GPS module (5) data forwarded by the first terminal (13) or directly receiving the alarm signal and the GPS module (5) data sent by the microcontroller (1) of the hearing aid through the GPRS module (2) of the hearing aid when the hearing aid is not connected with the first terminal (13).

9. A wireless transmission method applied to a hearing aid according to any one of claims 1 to 7, characterized in that:

acquiring data of a GPS module (5), data of a temperature sensor (6) and data of an impact sensor (7) and respectively carrying out analog-to-digital conversion on the data of the temperature sensor (6) and the data of the impact sensor (7);

acquiring and forwarding GPS module (5) data to a control switch (3) or a Bluetooth module (4);

judging whether the data of the temperature sensor (6) or the impact sensor (7) is abnormal;

if yes, generating an alarm signal and forwarding the alarm signal to the GPRS module (2) or the Bluetooth module (4).

10. The method according to claim 9, wherein: before the acquisition and forwarding of the GPS module (5) data to the control switch (3) or bluetooth module (4), the method further comprises,

judging whether the Bluetooth sensor is connected with equipment or not through the microcontroller (1), if yes, sending a connection control signal to the control switch (3) through the microcontroller (1), closing the control switch (3), and connecting the GPRS module (2) with the microcontroller (1) through signals; otherwise, the microcontroller (1) sends a disconnection control signal to the control switch (3), the control switch (3) is disconnected, and the signal connection between the GPRS module (2) and the microcontroller (1) is disconnected.
