The second distance detection unit in this embodiment of the present invention may select an existing distance sensor. According to different vehicle models, setting the range of the distance detection value between the first distance detection unit and the first terminal, and setting the range of the distance detection value between the second distance detection unit and the first terminal, you can choose Different distance sensors can determine whether the driver's driving behavior is abnormal by detecting the distance between the first terminal and the third terminal. Compared with video detection, the storage and processing volume of data is greatly reduced, and the cloud computing process is also avoided. In special cases such as tunnels and mountains, there is no signal detection terminal phenomenon.

The alarm unit can be used to send an alarm signal when the distance of the first terminal relative to the second terminal and the distance of the first terminal relative to the third terminal exceeds the distance of normal driving behavior, so as to remind the driver Correct abnormal driving behaviors in a timely manner to avoid accidents.

When the left hand is on the steering wheel and the right hand is on the gear lever, it is regarded as normal driving behavior. However, if the driver's left hand is always on the steering wheel and his right hand is always on the gear lever, it is regarded as abnormal driving behavior. If the driver's right hand is on the steering wheel and his left hand leaves the steering wheel for a long time, it is regarded as abnormal driving behavior.

When the trajectory detection unit detects that the driver's operating trajectory is in the normal behavior database, it is determined that the driver's driving behavior is normal driving; when the trajectory detection unit detects that the driver's operating trajectory is in the abnormal behavior database, it determines that the driver's operating trajectory is in the abnormal behavior database. For abnormal driving behavior, the alarm unit sends an alarm signal according to the abnormal behavior situation. For example, the trajectory detection unit detects that the first terminal is not on the steering wheel or the gear lever but is near the ear, and determines that the driver's driving is abnormal. driving behavior. When the trajectory detection unit detects that the driver's operating trajectory is neither in the normal behavior library nor in the abnormal behavior library, it is also determined as abnormal driving behavior, and the alarm unit also sends an alarm signal, for example: the trajectory detection unit detects that all The first terminal is kept away from the steering wheel and the gear lever for a long time.

Preferably, the control analysis unit compares the trajectory information detected by the trajectory detection unit with the behavioral trajectories/or driving states in the behavioral library, and compares the trajectory information detected by the trajectory detection unit with the behavioral trajectory/or driving state in the behavioral database, and determines the distance according to the first distance detection unit and the second distance. The detection unit and the distance information between the first terminals respectively judge whether the driving behavior of the driver is abnormal, and send the result to the alarm unit.

The temperature sensor detects whether the wearing unit is normally worn on the driver's arm. If only the locking detection component is detected in normal locking If the wearing state detection component detects that the temperature of the wearing component has not changed for a long time and is not within the set threshold range, it is determined that the driver does not wear the first terminal normally. The locking detection component in this embodiment can be selected from the existing wearing unit locking detection component, which will not be repeated here.
