202. The wearable device detects whether a user of the wearable device wears a shoe provided with a pressure sensor through an infrared detector, and if so, step 209 is executed; if not, step 203 to step 204 are executed.

In the embodiment of the present invention, the wearable device may think that the user wearing the shoe enters the water because the user accidentally falls into the water, and therefore needs to rescue, and step 209 is executed; the wearable device may also think that the user is consciously taking off the shoes to swim when not wearing the shoes and entering the water, but this also cannot confirm that no accident occurs during the swimming process of the user, so that it is necessary to further judge the health condition of the user's body and perform steps 203 to 204.

203. The wearable device detects a current heart rate of a user of the wearable device through a heart rate detector.

In the embodiment of the invention, the heart rate detector detects the heart rate by utilizing the principle that the blood of a human body can absorb green light in light, the wearable device controls the heart rate detector to emit the green light to the skin of a user of the wearable device through the LED lamp, when the heart beats, the blood in a blood vessel can be increased, the green light can be absorbed more, the intensity of the green light in penetrating light detected by the photosensitive sensor can be reduced, and therefore, the duration of one heart beat can be calculated by detecting the intensity of the green light in the penetrating light, and the current heart rate of the user of the wearable device can be calculated.

In the embodiment of the invention, the moment when the green light intensity is maximum is the moment when the blood absorbs the green light in the reflected light to be minimum, and is also the moment when one heart beat is finished; the moment when the intensity of the green light is minimum is the moment when the blood absorbs the green light in the reflected light the most, and is also the moment when one heart beat starts, so the moment when one heart beat starts to the moment when the same heart beat ends is set as the single heartbeat duration.

As an alternative embodiment, the way in which the wearable device detects the current heart rate of the user of the wearable device by the heart rate detector may comprise the following steps:

the wearable device emits light to the skin of a user of the wearable device and controls the photosensitive sensor to receive penetrating light of the light;

the wearable device acquires a first moment with maximum green light intensity and a second moment with minimum green light intensity in the penetrating light;

the wearable device calculates the duration between the first moment and the second moment through a heart rate detector, and determines the duration as the duration of a single heartbeat;

the wearable device calculates the current heart rate of the user of the wearable device according to the single heartbeat duration.

Wherein, implementing such an embodiment, the current heart rate of the user of the wearable device can be accurately measured.

204. The wearable device judges whether the current heart rate exceeds a preset heart rate range, if so, step 209 is executed; if not, step 205 is executed, and the preset heart rate range is the normal heart rate range set for the user of the wearable device.

In the embodiment of the present invention, by implementing steps 203 to 204, the health condition of the wearable device can be determined in a heart rate detection manner, so that the reliability of the wearable device in detecting the dangerous condition of the user is improved.

205. The wearable device judges whether the current body temperature of the user of the wearable device exceeds a preset body temperature range, if so, step 209 is executed; if not, executing the step 206 to the step 207, and setting the preset body temperature range as a normal body temperature range set for the user of the wearable device.

In the embodiment of the present invention, when the current heart rate of the user of the wearable device does not exceed the preset heart rate range, step 205 is executed. Wearable equipment can only judge through the mode that the rhythm of the heart detected whether the user appears drowned phenomenon in the fresh water, can not judge whether the user also appears drowned phenomenon in the sea water. Usually when the user of wearable equipment appears drowning the condition in the fresh water, the fresh water can be inhaled the lung by the user and then get into blood to the rhythm of the heart that leads to the user of wearable equipment can accelerate, so that surpass and predetermine the rhythm of the heart scope, so, can judge that the user appears drowning in the fresh water through the mode that the rhythm of the heart detected. However, when a user of the wearable device drowns in seawater, the seawater enters the lungs of the user to generate pulmonary edema, and the water does not enter the blood, so that the heart rhythm disorder of the drowned person is not caused, therefore, under the condition that the instant heart rate of the user of the wearable device is normal, the wearable device can adopt a body temperature detection mode to detect whether the user drowns in seawater, and the temperature of the seawater is usually lower than that of a human body, so that the drowning of the person in seawater can cause the reduction of the body temperature.

As an optional implementation, the manner in which the wearable device detects whether the user of the wearable device is drowned in seawater may include the following steps:

the wearable equipment detects the salinity value of the water in which the wearable equipment is positioned through a seawater salinity meter;

the wearable equipment judges whether the salinity value is in the standard seawater salinity value range;

if so, the wearable device detects the current body temperature of the user of the wearable device and judges whether the current body temperature is lower than the safe body temperature; if be less than, wearable equipment can confirm that wearable equipment's user appears drowned phenomenon, sends drowned SOS information to terminal equipment.

By implementing the embodiment, whether the user of the wearable device drowns in the seawater can be further detected in a body temperature detection mode, and the accuracy of the drowning alarm is improved.

206. The wearable device calculates a difference between the current body temperature and the current water temperature in the environment in which the wearable device is located.

In the embodiment of the present invention, the current body Temperature of the user of the wearable device and the current water Temperature in the environment where the wearable device is located may be measured by a Temperature sensor (Temperature Transducer).

207. The wearable device judges whether the absolute value of the difference is within the range of the abnormal temperature difference, if so, step 208 is executed; if not, the process is ended, and the abnormal temperature difference range is determined according to the physical quality of the user of the wearable device.

In the embodiment of the invention, the abnormal temperature difference range can be determined according to the physical quality of the user of the wearable device, and if the body temperature of the user of the wearable device is normal, the user of the wearable device can be considered to be healthy, so that the normal temperature difference range can be expanded, namely the abnormal temperature difference range is reduced; if the body temperature of the user of the wearable device is higher than the normal body temperature or lower than the normal body temperature, the user of the wearable device can be considered unhealthy, and therefore the normal temperature difference range can be narrowed, that is, the abnormal temperature difference range can be enlarged.

208. The wearable device outputs temperature abnormity early warning information which is used for reminding a user of the wearable device that the current water temperature is abnormal, and adverse effects are easily caused on the health of the user.

For example, if the user of the wearable device wants to swim in a river in winter, the wearable device detects the body temperature of the user and the current water temperature in the environment where the wearable device is located, and if the body temperature of the user of the wearable device is normal (e.g. 37 degrees celsius), the current temperature of the current river water is 5 ℃, the preset abnormal temperature difference range of the wearable equipment is 0-15, the absolute value 32 of the difference value between the current body temperature of the wearable device user and the current water temperature in the environment where the wearable device is located is larger than the preset abnormal temperature difference range and is 0-15, therefore, the absolute value of the difference value between the current body temperature and the current water temperature can be judged to be in the abnormal temperature difference range, the wearable device outputs temperature abnormity early warning information to prompt that the current water temperature of the user of the wearable device is too low relative to the current body temperature, and adverse effects can be caused on the body health of the user of the wearable device.

In the embodiment of the present invention, by implementing the steps 205 to 208, the health condition of the user of the wearable device can be accurately detected in a body temperature detection manner, and a wading suggestion can be provided for the user of the wearable device by determining the difference between the body temperature and the water temperature of the user of the wearable device, so as to better protect the health of the user of the wearable device.

209. The wearable device determines that a user of the wearable device is drowned, and sends a drowning alarm to the terminal device which establishes a pairing relation with the wearable device in advance.

In the method described in fig. 2, the drowning of the child can be automatically detected and alarm information can be sent out, so that the occurrence of the drowning accident of the child can be reduced. In addition, by implementing the method described in fig. 2, the current heart rate of the user of the wearable device can be accurately measured. In addition, by implementing the method described in fig. 2, the health condition of the wearable device can be determined by means of heart rate detection, so that the reliability of the wearable device in detecting the dangerous condition of the user is improved. In addition, by implementing the method described in fig. 2, whether the user of the wearable device drowns in the seawater can be further detected by means of body temperature detection, and the accuracy of the drowning alarm is improved. In addition, by implementing the method described in fig. 2, the health condition of the user of the wearable device can be accurately detected in a body temperature detection manner, and a wading suggestion can be provided for the user of the wearable device by determining the difference between the body temperature and the water temperature of the user of the wearable device, so that the health of the user of the wearable device can be better protected.
