Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a dialing control method provided in the first embodiment of the present invention. As shown in FIG. 1, the dialing control method disclosed in this embodiment includes the following steps:

S101. When the smart watch detects that the characteristic parameters obtained by the smart watch satisfy a preset condition, the smart watch detects a wrist raising motion of the user through the crown of the smart watch.

In the embodiment of the present invention, the characteristic parameters acquired by the smart watch may include: acceleration, ambient temperature, and user's heart rate.

In a specific implementation, the above smart watch detects that the characteristic parameters obtained by the smart watch meet the preset conditions in a specific manner:

When the characteristic parameter includes the acceleration, the smart watch detects the acceleration of the smart watch through an acceleration sensor, and if the detected acceleration is greater than a preset acceleration threshold, it is determined that the characteristic parameter meets the preset condition. Wherein, the acceleration sensor can detect the acceleration of the translation of the smart watch. If an event such as impact or falling occurs on the smart watch, a large translational acceleration will be generated at the moment of impact or bottoming out. Therefore, by comparing the translational acceleration acquired by the acceleration sensor with the acceleration threshold, dangerous events caused by the wearer of the smart watch falling, car accident or other physical collisions can be detected. or,

In the case where the above-mentioned characteristic parameters include the above-mentioned ambient temperature, the above-mentioned smart watch detects the ambient temperature through a temperature sensor, and if it detects that the above-mentioned ambient temperature is greater than a preset temperature threshold, then it is determined that the above-mentioned characteristic parameters meet the preset conditions. Wherein, the temperature sensor is a sensor installed on the smart watch for detecting the temperature of the environment where the smart watch is located. By comparing the ambient temperature with a preset temperature threshold, it can be detected whether the wearer of the smart watch is in danger of fire. or,

In the case that the characteristic parameters include the user's heart rate, the smart watch detects the user's heart rate through a heart rate sensor, and if it detects that the user's heart rate is less than or equal to a preset heart rate threshold, it is determined that the above characteristic parameters meet the preset condition. Wherein, the heart rate sensor is a sensor installed on a smart watch for detecting a user's heart rate. Since the heart rate is equal to or lower than the preset threshold, the user's physical condition is in danger. Therefore, by comparing the user's heart rate with the preset heart rate threshold, it can be detected whether the physical condition of the wearer of the smart watch is in danger.

In a specific implementation, the above-mentioned crown of the smart watch detects the user's wrist raising action in a specific way: detecting the wrist raising action through a distance sensor or a photosensitive sensor.

Wherein, the crown of the smart watch includes any of the following: a side touch screen, a joystick, and a trackball.

S102. If the smart watch detects N times of raising the user's wrist through the crown of the smart watch, generate a dialing control instruction, where N is a positive integer.

In an embodiment, the specific implementation manner in which the smart watch detects the user's N wrist raising actions through the crown of the smart watch may be as follows: the smart watch first obtains the distance sensor collected by the distance sensor in the crown of the smart watch M distance parameters between the back of the user's hand and the smart watch, where the above M is a positive integer greater than 1; secondly, the above smart watch extracts N groups of distance parameters from the above M distance parameters, and each group of the above N groups of distance parameters The parameter values of the multiple distance parameters in the distance parameter are continuously reduced, and the multiple sampling times corresponding to the above multiple distance parameters are adjacent to each other, and the above multiples are at least two; finally, the above smart watch judges that the above N When each group of distance parameters in the group of distance parameters matches the pre-stored distance parameters corresponding to the user's wrist raising actions, it is determined that N wrist raising actions of the user have been detected. The aforementioned distance sensor may be, for example, an infrared sensor or an ultrasonic sensor, a laser displacement sensor, and the like.

For example, suppose the pre-stored displacement parameters are:

a[a1, a2, a3, a4, a5, a6, a7, a8, a9, a10] (unit: mm)

A set of distance parameters between the back of the user's hand and the smart watch collected by the distance sensor in the crown of the smart watch is:

b[b1, b2, b3, b4, b5, b6, b7, b8, b9, b10] (unit: mm)

Then, if |bi-ai|≤5 (unit: mm), it is considered that the distance parameter between the back of the user’s hand and the smart watch collected by the distance sensor in the crown of the smart watch corresponds to the pre-stored user’s wrist raising action The distance parameter matches.

Assume that the above-mentioned smart watch obtains 60 distance parameters between the back of the user’s hand and the smart watch collected by the distance sensor in the crown of the above-mentioned smart watch, and extracts three sets of distance parameters among the above-mentioned 60 distance parameters.

a[100, 90, 80, 70, 60, 50, 30, 20, 10, 10] (unit: mm)

The smart watch judges that each of the three sets of distance parameters matches the pre-stored distance parameters corresponding to the user's wrist raising actions, and therefore determines that the user's three wrist raising actions have been detected.

In another embodiment, the specific implementation manner in which the smart watch detects the user's N wrist raising actions through the crown of the smart watch may be as follows: the smart watch first acquires the data collected by the photosensitive sensor in the crown of the smart watch The M ambient brightness parameters; secondly, the above smart watch extracts N groups of ambient brightness parameters in the above M ambient brightness parameters, and the parameters of multiple ambient brightness parameters in each group of ambient brightness parameters in the above N groups of ambient brightness parameters The value continuously decreases, and the plurality of sampling times corresponding to the above-mentioned multiple environmental brightness parameters are adjacent to each other, and the above-mentioned multiples are at least two; finally, the above-mentioned smart watch judges that each group of the above-mentioned N groups of environmental brightness parameters In a case where all the environmental brightness parameters match the pre-stored environmental brightness parameters corresponding to the user's wrist raising actions, it is determined that N wrist raising actions of the user have been detected.

For example, suppose the pre-stored environment brightness parameters are:

a[a1, a2, a3, a4, a5, a6, a7, a8, a9, a10] (unit: lm)

The aforementioned smart watch obtains a set of environmental brightness parameters collected by the photosensitive sensor in the crown of the smart watch as follows:

b[b1, b2, b3, b4, b5, b6, b7, b8, b9, b10] (unit: lm)

Then, if |bi-ai|≤10 (unit: lm), it is considered that the ambient brightness parameters between the back of the user’s hand and the smart watch collected by the photosensitive sensor in the crown of the smart watch are consistent with the pre-stored user’s wrist raising action The corresponding ambient brightness parameters are matched.

For another example, assume that the above-mentioned smart watch obtains 60 ambient brightness parameters between the back of the user's hand and the smart watch collected by the photosensitive sensor in the crown of the smart watch, and extracts 3 groups of ambient brightness from the above-mentioned 60 ambient brightness parameters. parameters, the above three groups of environmental brightness parameters are:

a1[141, 122, 101, 82, 62, 51, 32, 11] (unit: lm)

a2[142, 121, 100, 81, 61, 50, 31, 10] (unit: lm)

a3[139, 119, 100, 81, 63, 50, 31, 9] (unit: lm)

The ambient brightness parameters corresponding to the pre-stored user's wrist raising action are:

a[140, 120, 100, 80, 60, 50, 30, 10] (unit: lm)

The smart watch judges that each of the above three sets of ambient brightness parameters matches the pre-stored ambient brightness parameters corresponding to the user's wrist-raising actions, and then determines that the user's wrist-raising actions have been detected three times.

S103. The above-mentioned smart watch sends the above-mentioned dialing control instruction to the mobile terminal communicatively connected with the above-mentioned smart watch, and the above-mentioned dialing control instruction is used to instruct the above-mentioned mobile terminal to dial an emergency number.

In the embodiment of the present invention, the above dialing control command may be a control command for dialing an emergency number, a control command for dialing a preset family number, or a control command for cyclically dialing any preset number.
