It is defeated close to voltage signal that pedestrian is converted to useful pedestrian close to current signal by the preamplifier of electric infrared sensor of the human body
Out, the pedestrian of output is sent to central processing unit close to voltage signal by pyroelectric human body infrared sensor.
In step S204, central processing unit receives pedestrian after signal, control remind component by sound and/
Or vibration and/or light carry out anti-collision reminding to wearer.
In embodiments of the present invention, it is close to receive the pedestrian that pyroelectric human body infrared sensor is sent for central processing unit
After signal, control reminds component to carry out anti-collision reminding to wearer by sound and/or vibration and/or light, while passing through lamp
The anti-collision reminding mode of optical flare can also play reminding effect to the pedestrian close to wearer.
Before control reminds component to carry out anti-collision reminding to wearer by sound and/or vibration and/or light, preferably
Ground, central processing unit receive pedestrian after signal, and control non-contact speed measurement sensor is to the pedestrian's close to wearer
Relative moving speed is detected, and when the relative moving speed detected is more than preset threshold speed, component is reminded in control
Anti-collision reminding is carried out to wearer by sound and/or vibration and/or light, to improve the rationalization journey of anti-collision reminding
Degree, and then improve the intelligence degree of smartwatch.
It is another before control reminds component to carry out anti-collision reminding to wearer by sound and/or vibration and/or light
Preferably, central processing unit receives pedestrian after signal, pedestrian and pendant of the command range sensor to close wearer
The distance between wearer detects, and when the distance detected is lower than preset safe distance, control reminds component to pass through sound
Sound and/or vibration and/or light carry out anti-collision reminding to wearer, to improve the rationalization degree of anti-collision reminding, in turn
Improve the intelligence degree of smartwatch.
It is another before control reminds component to carry out anti-collision reminding to wearer by sound and/or vibration and/or light
Preferably, central processing unit receives pedestrian after signal, control microphone to pedestrian's footsteps around wearer into
Row detection, obtains the volume of footsteps, distance of the pedestrian apart from wearer is judged according to the volume, to determine whether
It needs by reminding component to carry out anti-collision reminding to wearer, to improve the intelligence degree of smartwatch.
In embodiments of the present invention, according to motion sensor senses to motion state determine whether wearer is just being expert at
It walks, when determining wearer just when walking, being detected by pyroelectric human body infrared sensor whether there is human body around wearer
Generated infrared ray generates pedestrian close to signal, and by pedestrian and is sent to center close to signal when detecting the infrared ray
Processing unit, central processing unit receive pedestrian after signal, and control reminds component to carry out anti-collision reminding to wearer, from
And avoid because user does not pay attention to close pedestrian, and there is the case where hitting other side, the timeliness of anti-collision reminding is improved, into
And improve safety when user's walking and the intelligence degree of smartwatch.
