In the present embodiment, S401-S403 is identical with the S101-S103 of above-described embodiment, and this will not be repeated here.

S404 when determining that continuous strokes stop based on each judging result, persistently obtains geomagnetic sensor and exists The geomagnetic data acquired during user swimming；

In the present embodiment, S404-S407 is the specific implementation of S104 in above-described embodiment.

Determine that continuous strokes stopping can specifically refer to based on each judging result：Obtained by lasting scheduled duration Judging result be to show that user does not send out arm stroke, alternatively, when obtained continuous multiple judging results show User does not send out arm stroke, it can be assumed that continuous strokes stop, being not limited thereto certainly.

During user swims, geomagnetic sensor in the electronic equipment that user is worn can with continuous collecting magnetic number According to therefore, which can continue to obtain the ground that geomagnetic sensor is acquired during the user swims Magnetic data.

It should be noted that since the geomagnetic data that the geomagnetic sensor is acquired during user swims is continuously to believe Number, for the ease of analysis, one section of geomagnetic data, i.e. data segment corresponding to certain amount sampled point can be obtained every time.Also, The specific length value of the length of the geomagnetic data obtained every time does not limit herein.

Also, the geomagnetic data acquired in the swimming information detector can be the earth magnetism of all axis of geomagnetic sensor Data；Certainly, in order to reduce calculation amount, acquired geomagnetic data can be only the ground magnetic number that can most reflect the axis turned round According to, wherein, it can most reflect that the geomagnetic data of an axis turned round can be determined according to statistical analysis.Assuming that the x-axis of geomagnetic sensor To be directed toward finger orientation, i.e., direction of advance, z-axis are upper and lower directions, and through analysis it is found that z-axis can most reflect touch turn, because This, in order to reduce calculation amount, acquired geomagnetic data can be only the geomagnetic data of z-axis.

Accessed geomagnetic data is added sequentially in second circulation array by S405；

After getting geomagnetic data every time, which can add in accessed geomagnetic data Into second circulation array, in this way, a data segment to be analyzed can be obtained every time, and then, it can be to each data segment It is analyzed.It should be noted that when accessed geomagnetic data is added to second circulation array, add since end Enter, in this way, data are removed earlier in second circulation array, ensure that the data age of second circulation array.

Wherein, the length of second circulation array can be identical with the length of the geomagnetic data obtained every time, in this way, by being obtained After the geomagnetic data got is added to second circulation array, the current data of the second circulation array is only including current acquired The geomagnetic data arrived；And the length of second circulation array can also be more than the length of geomagnetic data acquired every time, in this way will After accessed geomagnetic data is added to second circulation array, the current data of the second circulation array both includes currently being obtained The geomagnetic data got also includes all or part of data of the geomagnetic data acquired in the last time.

S406 after geomagnetic data is added in the second circulation array, is determined current in the second circulation array The plateau data of geomagnetic data and the dynamic variable quantity based on time-domain difference；

Wherein, the method for determination of the plateau data of the current geomagnetic data in the second circulation array can include but It is not limited to：Period continuity detection mode, the steady detection mode of frequency, time-frequency detection mode etc..

In addition, empty in swimming recruit stable swimming state, when strokes pause or pool side are turned round, can interrupt smoothly Swimming state continually looks for stable swimming state, the difference of adjacent two kinds of swimming states, you can judge whether after turning round There is the generation of touch turn, hence, it can be determined that the plateau data of current geomagnetic data and the dynamic based on time-domain difference Variable quantity.

S407 based on the plateau data determined and dynamic variable quantity, determines the swimming number of turns of the user.

Optionally, it is described based on the plateau data determined and dynamic change in a kind of specific implementation The step of measuring, determining the swimming number of turns of the user, can include：

When detecting the presence of the target dynamic variable quantity more than default variable quantity threshold value, the target dynamic variable quantity is judged Whether the adjacent data of corresponding geomagnetic data belongs to plateau data, if so, the swimming number of turns of completion by the user Increase half-turn, obtain the current swimming number of turns of completion of the user.

It is emphasized that it is before stable swimming state that user, which during swimming, turns round, can be beaten when turning round Disconnected stable swimming state, and after turning round, stable swimming state can be restored, therefore, steady-dynamic change-is stable The foundation that continuous process can be turned round as identification.It based on the processing thought, is turned round to identify, i.e., whether needs to increase and swim The number of turns, it is more than the target dynamic variable quantity for presetting variable quantity threshold value, also, be more than when detecting the presence of that can detect whether to exist During the target dynamic variable quantity of default variable quantity threshold value, the adjacent data of geomagnetic data corresponding to the target dynamic variable quantity is judged Whether plateau data are belonged to, if so, the swimming number of turns of completion of the user is increased half-turn.

Optionally, in order to avoid being that user midway is turned round, the accuracy of number of turns identification, described judgement target dynamic are improved Whether the adjacent data of geomagnetic data corresponding to variable quantity belongs to plateau data, if so, the swimming pool that the user is completed The number of turns increases the step of half-turn, can include：

Judge whether the adjacent data of geomagnetic data corresponding to the target dynamic variable quantity belongs to plateau data, and sentence Whether disconnected target duration is higher than preset duration threshold value and/or whether target strikes number higher than preset times threshold value, if it is determined that Result is to be, the swimming pool number of turns which is completed increases half-turn；Wherein, a length of current time increases with last during the target Duration when adding half-turn between the corresponding moment, the target strike number to draw time number in the target duration.

It is understood that it is that the swimming information detector is identifying for the strike premise of the judgement of number of target While the number of turns of swimming also when identification draws and time strikes number, the target can be obtained and struck number, and then drawn based on the target Waterside number performs corresponding judgement.

In a particular application, which can indicate that user inputs the length of swimming pool, and then, Ke Yigen According to the length of swimming pool and the conventional levels value for distance of striking, the preset times threshold value is obtained；Alternatively, the swimming information detector Can the preset times threshold value be obtained according to the conventional length of swimming pool and the conventional levels value for distance of striking.

Similar, which can indicate that user exports the length of swimming pool, and then, it can be according to swimming pool Length and with speed conventional levels value, obtain the preset duration threshold value；Alternatively, the swimming information detector can be according to trip The conventional length of swimming and the conventional levels value with speed, obtain the preset duration threshold value.

With reference to a concrete application example, a kind of swimming information detecting method provided herein is introduced.Wherein, should Swimming information includes strike number, swimming stroke and the swimming number of turns.Also, the electronic equipment is wearable watch, wherein, accelerate The x-axis for spending sensor is directed toward finger orientation, and z-axis vertical surface is downward, and three axis of geomagnetic sensor are directed toward and acceleration transducer It is identical.
