Specific embodiment
Below by drawings and Examples, technical scheme is described in further detail.
Step number assay method provided in an embodiment of the present invention, is applied to (the letter in following embodiments of customer mobile terminal equipment
Claim user terminal) in, such as smart mobile phone.Or can also be intelligent wearable equipment with processing function.User terminal
In be built-in with gravity sensor, acceleration transducer, for carrying out the collection of the basic data needed for the step number assay method.
Wherein, when the position of user terminal changes, collected by three axles (x, y, z) of gravity sensor
Data are changes.And pass through the acceleration value that acceleration transducer (G-sensor) can return three axle of x, y, z.
Such as, in a specific example, user terminal keeps flat on the table, and x-axis is defaulted as 0, and y-axis gives tacit consent to 0, and z-axis is write from memory
Recognize 9.81；Which is put down on the table, z-axis is -9.81；Be tilted to the left, x-axis be on the occasion of；It is tilted to the right, x-axis is negative value；To
Upper inclination, y-axis are negative value；Downward-sloping, y-axis be on the occasion of.Based on this principle, acceleration transducer can be applied to this reality
Apply in the step number assay method of example proposition.
Fig. 1 be step number assay method flow chart provided in an embodiment of the present invention, below as shown in figure 1, to the present invention enforcement
The step number assay method that example is provided is illustrated.
In the present embodiment, step number assay method comprises the steps：
Step 101, user terminal receive acceleration transducer and move according to the first user that the first prefixed time interval is gathered
The acceleration information of movable property life；
Default timing statisticses section is set with system, and collection and the record to acceleration information is from default timing statisticses
The initial time of section was recorded for a cycle to termination time.After default timing statisticses section terminates, all of number
According to clearing can be reset.Wherein initial time and termination time are specified based on system time.Such as initial time is set to every
It 0：00：00, it is daily 23 to terminate set of time：59：59.
In this example, using the sampling period of Fixed Time Interval, the collection of acceleration information is carried out.
Such as, the setting data sampling interval is 500ms, gathers a point per 500ms, then can gather 120 within 1 minute
The data of point.
In this example, acceleration transducer is preferably 3-axis acceleration sensor；Remember in the acceleration information for being collected
Record has acquisition time information.
Step 102, acceleration information is stored in the first data acquisition system；
Step 103, monitors the data volume of the acceleration information in the first data acquisition system；
Specifically, often collect an acceleration information, be stored in data acquisition system, and to data acquisition system in data
Amount is monitored.
Be stored with the data base of user terminal setting data amount threshold value, and monitoring is stored in the data volume in data acquisition system
The threshold value whether has been reached, if be not reaching to, next acceleration information in continuing to data acquisition system, has been stored.
Step 104, when data volume reaches setting data amount threshold value, according to acquisition time information, by the first data acquisition system
In acceleration information be divided into multigroup；
Wherein, two acceleration informations of adjacent time collection are included in per group, and each acceleration information is only present in
In one group.So that setting data amount threshold value is 3000 as an example, then can be divided into 1500 groups of data in data acquisition system and be processed.
If setting data amount threshold value is 3000, when the quantity of the acceleration information in data acquisition system is more than 3000, enter
Row once-through operation, it is therefore an objective to avoid data acquisition system too big, reduces the time that single computing is consumed.Simultaneously without constantly being counted
Calculate, can rationally using system resource.
Step 105, the data variation amount in calculating per group between two acceleration informations；
Specifically, the computational methods of data variation amount can have multiple.
Preferred in this example, with the data variation amount between overall two acceleration informations of calculating.
Computational methods such as following formula 1：
In addition the data per two acceleration informations in group in X-direction, Y-direction and Z-direction can also be calculated respectively to become
Change amount.
In this step, X-direction, Y-direction and Z-direction are respectively three axle axial directions of gravity sensor.
Step 106；Determine the data variation amount of each group acceleration information whether in the range of the first threshold for setting；
Wherein, the determination of first threshold scope has at least following two modes：
First kind of way, according to the sample frequency of acceleration information, and the user profile of first user is determined.
Wherein user profile can include in height data, age data or the stride data and cadence data of user
Plant or several.
Just so that user profile is as stride data as an example, according to stride data, first threshold scope can pass through stride data
Calculate with the product in sampling interval and obtain.Such as, the normal step size of first user is between 0.5 meter 1.1 meters, cadence be 1 step/
Second, the sampling interval is 500ms, then first threshold scope is [0.25,0.55] rice.
Likewise, if height data, age data, the conversion relation that can directly press according to them and stride data
Corresponding stride data is obtained, first threshold scope is then obtained again by the way.
The second way, the first threshold scope of first user are determined based on the multiple pretest data of first user
Fixed data.
Therefore can be according to the user profile of first user, direct access first threshold scope corresponding with first user.
Here, user profile is most preferably ID, can obtain using to first by the ID of first user
The first threshold scope of family customization.
In addition, in more preferably embodiment, user profile can also be the height data of user, that is, think identical height
The first threshold scope of user is all identical, correspondingly obtains the first threshold scope being consistent with the height by user's height data.
Certainly can be being divided according to sex, age again in the case of identical height, corresponding different threshold ranges, according to
Family age, sex, height, correspondingly obtain corresponding first threshold scope.
By this step, it is achieved that the practical situation according to first user carries out data validity examination, so that succeeding in one's scheme
The step number for entering is effective.
The purpose that first threshold scope arranges upper and lower bound is that it is possible to be identified and do not move or translational speed mistake
In slow situation, the situation of walking can not be can be regarded as, and identify that mobile too fast or amplitude is excessive, such as be hurried up, ride
Or situation by bus.
Step 107, when one group of data variation amount is in the range of the first threshold for setting, determines one group of corresponding counting
It is worth for 1, is otherwise 0；
Specifically, if the data variation amount drawn according to formula 1 is in the range of first threshold, this group of data are considered as
It is valid data, the corresponding count value of the group is set to 1.If exceeding first threshold scope, this group of data are considered as invalid data,
Count value is set to 0.
Step 108, counts to the count value of each group in the first data acquisition system, obtains the accumulative of the first group data set conjunction
Step number, and store.
Specifically, per group in data acquisition system of count value is added, the numerical value for obtaining is exactly the accumulative of effective step number,
Add up step number.
Step 109, determines the duration for whether having reached default timing statisticses section to the statistics duration for adding up step number；
Specifically, after counting statistics is carried out to the accumulative step number that a group data set is closed each time, will confirm to tired
The length at the default timing statisticses end whether the statistics duration of meter step number is counted required for reaching.
To adding up the statistics duration of step number, can be according to during the collection of the acceleration information for being used for generating the accumulative step number of the group
Between information determining, be compared to really by using the acquisition time and termination time of the acceleration information for finally obtaining
Statistics duration whether has been reached determine.
In addition it is also possible to be to trigger determination statistics duration to reach default timing statisticses section by system clock.Such as exist
Daily 23：59：59, accumulative step number statistics instruction is generated, is counted for the multigroup accumulative step number to having generated.
If be not reaching to, repeat the method according to abovementioned steps 101-109, continue to obtain the tired of next group data set conjunction
Meter step number.
Specifically, user terminal continues to the first user that acceleration transducer is gathered according to the first prefixed time interval
The mobile acceleration information for producing, and acceleration information is stored in the second data acquisition system, for obtaining next group data set
The accumulative step number that closes, and per group of accumulative step number is all stored.
If to having reached statistics duration, executing following step 110.
Step 110, the accumulative step number that each group data set for obtaining is closed is counted, obtained in default timing statisticses section
The motion step number of first user in default timing statisticses section.
Specifically, the accumulative step number that each group data set is closed is overlapped, obtains the total motion step in statistical time range
Number.
The step number be data validity examination has been carried out according to the practical situation of first user after the step number that obtains,
Improve accuracy.
By user terminal, the motion step number of first user in the default timing statisticses section that obtains can be shown
Show, for the situation that user easily recognizes oneself actual walking operation in each setting cycle.
Further, after default timing statisticses section terminates, accumulative step number and motion step number are reset to 0 respectively,
So as to directly carry out the step number statistics of next default timing statisticses section.
