313, wearable device judges whether above-mentioned energy consumption values are more than preset energy consumption figures, when above-mentioned energy expenditure
When value is more than preset energy consumption figures, step 314 is executed；Conversely, when above-mentioned energy consumption values are not more than preset energy consumption figures
When, terminate this flow.
314, wearable device sends warning information of drowning to the first electronic equipment being connect in advance with wearable device, should
Drowned warning information is used to prompt the wearer of wearable device to there is drowned danger.
For step 311~314, wearable device can be in the direction of motion for the wearer for judging wearable device
It, can be further wearable to judge by obtaining energy consumption values after direction far from the default safety zone in water environment
Whether the energy expenditure that the wearer of equipment is current excessive, when wearable device wearer to insecure area (far from water
Default safety zone in environment) swimming when, since the status of the water area of insecure area is complicated, wearer generally requires consumption more
Therefore more energy when wearable device judges that energy consumption values are more than preset energy consumption figures, illustrates wearable device
Wearer at this time muscle power overdraw, be in used-up state, therefore, if wearer continue toward insecure area swim
Swimming is easy to happen drowning danger, it is seen then that the embodiment of the present invention, it can be in the direction of motion for the wearer for judging wearable device
After the direction far from the default safety zone in water environment, the energy expenditure of the wearer of wearable device is further judged
Whether value is more than preset energy consumption figures, when energy consumption values are more than preset energy consumption figures, to advance with wearable device
First electronic equipment of connection sends warning information of drowning, and improves the accuracy of drowned warning information.
315, wearable device determines that above-mentioned motion change rule and default swimming exercise changing rule mismatch, and to
The second electronic equipment that wearable device connects in advance sends alarming drowning information, and the alarming drowning information is wearable for prompting
Drowning danger occurs for the wearer of equipment.
As it can be seen that passing through method described in Fig. 3, it can be determined that movement of the wearer of wearable device in water environment becomes
Whether law matches with default swimming exercise changing rule, when matching and the direction of motion is far from default in water environment
When the direction of safety zone, illustrate that wearer swims to the direction of insecure area, it is understood that there may be drowned risk, therefore
Warning information of drowning is sent, drowned to wearer early warning can be sent out in advance, improve the promptness of drowned early warning；And ought not
Timing illustrates that wearer is in water environment but is not swimming, and there are drowning dangers by wearer, send out alarming drowning at this time, improves
The probability that wearer is rescued.
In addition, by method described in Fig. 3, the raw acceleration data of the wearer based on wearable device, right
The raw acceleration data carries out the wearer of wearable device being determined in water environment after a series of conversions and calculating
In the direction of motion, the accuracy of the direction of motion got can be improved.
In addition, by method described in Fig. 3, it can be by the way that the shooting direction of the camera of wearable device be adjusted to
The shooting direction to match with the direction of visual lines of wearer so that the ambient image that wearable device takes can be more intuitive
Reflection current time wearer where geographical location, can further increase wearable device according to ambient image judge wear
The accuracy of wearer's local environment.
In addition, by method described in Fig. 3, preset database quick obtaining to the current energy of wearer can be passed through
Consumption figures is measured, the efficiency of drowned early warning is improved, and, the customized individual database of wearer for establishing wearable device is also
The individual demand that user can be met improves the Experience Degree of user.
Can be remote in the direction of motion for the wearer for judging wearable device in addition, by method described in Fig. 3
After direction from the default safety zone in water environment, further judge that the energy consumption values of the wearer of wearable device are
It is no to be more than preset energy consumption figures, when energy consumption values are more than preset energy consumption figures, it is connect in advance to wearable device
The first electronic equipment send drown warning information, improve the accuracy of drowned warning information.
