After the terminal device obtains the second acceleration curve trajectory, the terminal device determines D and E from the second acceleration curve trajectory, wherein D is a time distance (peak-to-peak interval) between two peaks, E is an amplitude (peak-Gu Fuzhi) of the acceleration, and wherein the resolution R of E (in m/s² ) The calculation formula of (2) is formula (2-2).

Where N is a constant, g is the gravitational acceleration, n×g is the measurement range, and P represents the sensor resolution.

Preferably, in practical application, when the sensor for acquiring acceleration is an 8-bit sensor, the N value is 4 and the P value is 256.

The terminal device judges whether D and E satisfy preset conditions, specifically, when the terminal device determines that D is in the range of 250 to 1000ms and E is greater than 10R at the same time and the number of waveforms conforming to D being in the range of 250 to 1000ms and E being greater than 10R is greater than 140 in 1 minute, the terminal device determines that the user is running, i.e., the terminal device determines that the user is performing the second exercise.

202. The terminal device determines that the second motion is uniform motion.

In the process of performing the second movement by the user, the terminal equipment can acquire the third swing arm amplitude of the user in the third preset time period and the fourth swing arm amplitude of the user in the fourth preset time period through the accelerometer.

It will be appreciated that the acceleration value on the sensitive axis of the accelerometer of the terminal device will exhibit a sinusoidal variation during the second movement by the user. The terminal device may determine whether the second motion performed by the user is uniform motion by an acceleration value on a sensitive axis of the accelerometer.

For example, the terminal device may acquire the average amplitude of the swing arm of the user from the fifth minute to the tenth minute in the second movement as the third swing arm amplitude of the third preset duration, and the average amplitude of the swing arm from the tenth minute to the fifteenth minute in the second movement as the fourth swing arm amplitude of the fourth preset duration, compare the third swing arm amplitude with the fourth swing arm amplitude, and determine that the second movement is uniform movement when the difference between the third swing arm amplitude and the fourth swing arm amplitude is less than the second preset threshold. The second preset threshold may be that the difference between the amplitude of the third swing arm and the amplitude of the fourth swing arm is less than 5%, and it should be noted that the second preset threshold may also be other thresholds.

203. The terminal device obtains at least one set of motion parameters of the second motion.

After the terminal equipment determines that the motion speed of the second motion is uniform, the terminal equipment acquires at least one group of motion parameters of the second motion.

Specifically, during the second movement of the user, the terminal device may acquire movement parameters with different movement speeds, that is, acquire at least one set of movement parameters, where movement speeds corresponding to each set of movement parameters in the at least one set of movement parameters are different, and the movement speed corresponding to each set of movement parameters in the at least one set of movement parameters is a uniform speed, that is, when each set of movement parameters is acquired, the movement speed of the user is a uniform speed. It should be noted that each set of exercise parameters in the at least one set of exercise parameters includes at least a second exercise duration, a second exercise distance, and a second exercise heart rate.

For example, the terminal device may obtain the motion parameters corresponding to k groups of different constant speeds respectively as follows:

motion parameters of the first constant velocity:

the second exercise time length is ta, the second exercise distance is Da, the first exercise step number is Sa, and the second exercise heart rate is HRma; the second exercise duration ta may be obtained by a clock of the terminal device, the second exercise distance Da may be obtained by a GPS, and the second exercise heart rate HRma may be obtained by a sensor.

Motion parameters of the second constant velocity:

the second exercise time length is tb, the second exercise distance is Db, the first exercise step number is Sb, and the second exercise heart rate is HRmb; the second movement duration tb can be obtained by a clock of the terminal device, the second movement distance Db can be obtained by a GPS, and the second movement heart rate HRmb can be obtained by a sensor.

Motion parameters for kth constant velocity:

the second exercise time length is tk, the second exercise distance is Dk, the first exercise step number is Sk, and the second exercise heart rate is HRmk; the second movement duration tk can be obtained through a clock of the terminal equipment, the second movement distance Dk can be obtained through a GPS, and the second movement heart rate HRmk can be obtained through a sensor.

204. The terminal device determines a functional relation f (HRm) of the movement speed and the movement heart rate.

After the terminal equipment acquires at least one group of motion parameters, the terminal equipment determines a second motion speed corresponding to each group of motion parameters of the at least one group of motion parameters.

For example, the terminal device acquires k groups of motion parameters, and determines a second motion speed according to a second motion duration and a second multiple motion distance of each group of motion parameters in the k groups of motion parameters.

Specifically, the second motion speed va=da/ta corresponding to the first constant speed, the second motion speed vb=db/tb corresponding to the second constant speed, and the second motion speed vk=dk/tk corresponding to the nth constant speed.

After the terminal device determines the second movement speed, the terminal device determines a functional relation f (HRm) between the movement speed and the movement heart rate according to the second movement speed and the second movement duration.

Specifically, the terminal device determines a functional relationship f (HRm) between the movement speed and the movement heart rate from the corresponding relationship between the second movement speed and the second movement heart rate, for example, the terminal device determines the corresponding relationship between the second movement speed and the second movement heart rate from Va corresponding HRma, vb corresponding HRmb, …, vk corresponding HRmk, and learns to obtain the functional relationship f (HRm) between the movement speed and the movement heart rate from the corresponding relationship between the second movement speed and the second movement heart rate. Namely, when the exercise heart rate HRm of the user is obtained, the terminal device can obtain the exercise speed V, v=f (HRm) corresponding to the exercise heart rate HRm through the function relation f (HRm) of the exercise speed and the exercise heart rate.

It will be appreciated that the at least one set of movement parameters may further comprise a first number of movement steps S1 by which the terminal device may obtain the movement step L of the user. For example, l=da/S1.

205. The terminal device determines that the user is performing a first movement.

In this embodiment, the method for determining that the user is performing the first movement by the terminal device is similar to the method for determining that the user is performing the second movement by the terminal device instep 201, and reference is made to step 201 specifically, and details are not repeated here.

206. The terminal device determines that the first motion is uniform motion.

In this embodiment, the method of determining that the first motion is uniform motion by the terminal device is similar to the method of determining that the second motion is uniform motion by the terminal device instep 202, and reference is made to step 202 specifically, and details are not repeated here.

207. The terminal equipment acquires a first exercise heart rate and a first exercise duration when the user performs a first exercise.

When the terminal equipment recognizes that the user is performing the first movement, the terminal equipment records the starting time and the ending time of the first movement through a timer, so that the first movement duration can be determined according to the starting time and the ending time.

When the terminal equipment determines that the user performs a first exercise and the exercise heart rate of the user reaches the heart rate platform period, the terminal equipment acquires the heart rate corresponding to the heart rate platform period and takes the heart rate as the first exercise heart rate. Specifically, the terminal device may obtain a first exercise heart rate of the user while performing the first exercise through the heart rate sensor. For example, when the heart rate sensor is a photoelectric sensor, the photoelectric sensor is worn on a body surface of a human body, so that a reflected signal of the human body on light is obtained, and the exercise heart rate of the user is determined from the reflected signal. It can be understood that the initial heart rate of the user starts to rise linearly from the quiet heart rate HR0 and then keeps constant by the heart rate threshold HRm, that is, HRm is the heart rate of the heart rate plateau, and when the heart rate of the user reaches the heart rate plateau, the terminal device acquires the heart rate HRm corresponding to the heart rate plateau and uses the heart rate HRm as the heart rate of the first exercise.

208. The terminal equipment determines a second movement step number corresponding to the first movement duration.

The terminal equipment acquires a second movement step number of the user walking in the first movement time through the triaxial accelerometer.

209. The terminal device calculates a first movement distance traveled by the user during a first movement time.

Specifically, the terminal device may calculate the first movement distance according to formula (2-3), where formula (2-3) is:

D＝α*L*S+β*f(HRm1)*t (2-3)

wherein D is a first movement distance, alpha and beta are constant coefficients which are more than or equal to O and less than or equal to 1 respectively, L is a movement step length, S is a second movement step number, and t is a first movement time length.

Preferably, in practical application, α and β may be set to 0.5, respectively.

It will be appreciated that, through equation (2-3), the distance traveled by the user in performing the first exercise may be obtained by the terminal device through the first exercise heart rate HRm1, the exercise step size, and the exercise step number, and thus, the terminal device may still obtain the distance traveled by the user in performing the first exercise without GPS or GPS shutdown.

210. The terminal device corrects the formula (2-3).

In practical application, when the area where the user performs the first movement covers the GPS, the terminal device may also obtain, through the GPS, the first movement distance traveled by the user during the first movement, and correct α and β in the formula 2-3 by using the first movement distance, so as to obtain more accurate α and β, thereby making the formula (2-3) more accurate.

Alternatively, the terminal device may preset the target distance by acquiring the number of steps of travel and the exercise heart rate of the user at the target distance, and correcting α and β in the formula (2-3) according to the target distance, the number of steps of travel and the exercise heart rate.

In this embodiment, the terminal device determines a functional relation f (HRm) between the motion speed and the motion heart rate and a motion step length of the user by acquiring at least one set of motion parameters of the second motion, and calculates a first motion distance corresponding to the first motion according to the functional relation f (HRm), the motion step length, the first motion heart rate of the first motion and the first motion duration of the first motion when the user performs the first motion. Therefore, in this embodiment, the functional relation f (HRm) and the motion step length of the user are determined through the second motion, so that when the GPS is not covered or closed in the motion area of the first motion, the terminal device can still calculate the first motion distance corresponding to the first motion through the functional relation f (HRm), the motion step length, the first motion heart rate of the first motion and the first motion duration of the first motion, thereby improving the accuracy of calculating the motion distance.
