Reduce and survey probability by mistake, as user can also detect the presence of water environment when taking a shower or washing one's hands, but location information shows and made
User is currently in residential block, and heart rate and blood oxygen saturation are normal, then judges that user is not in drowned state.
When optical sensor measurement heart rate and blood oxygen saturation, as user is in drowned state, heart rate can with when
Between first speed and then slow down rapidly, that is, from rapid heart beat to heartbeat it is too slow, it is possible thereby to the boundary value by setting heartbeat
To judge whether heart rate is in normal condition, meanwhile, alveolar collapse and atelectasis can occur for people when drowned, QS pulmonary shunt, cause
Systemic hypoxia, to a certain degree under will produce hypoxemia, and hypoxemia can be measured by blood oxygen saturation, typically be recognized
Normally it is not less than 94% for blood oxygen saturation, hypoxemia is then regarded as below 90%；It is possible thereby in above-mentioned zone scope
It is interior to set boundary value to judge user whether in drowned state.
The preferred embodiments of the present invention are the foregoing is only, embodiment is used for structure, function and the effect for understanding invention, and
It is not used in and limits the scope of the invention.The present invention can have various modifications and variations, all in the spirit and principles in the present invention
Within, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
