Embodiment three
With reference to Fig. 4, Fig. 4 is the interaction flow of the first bluetooth equipment provided in an embodiment of the present invention and the second bluetooth equipment
Figure, as shown in figure 4, the first bluetooth equipment is mobile phone, the second bluetooth equipment is equipment in addition to mobile phone, abbreviation bluetooth equipment,
This method may comprise steps of：
Bluetooth connection is set up in S401, request；
S402, sends the walking data of bluetooth equipment；
S403, obtains the walking data of mobile phone；
S404, the walking data of the walking data of mobile phone and bluetooth equipment are contrasted.
For purposes of illustration only, being below the first bluetooth equipment and the second bluetooth equipment preferably interaction flow, details are as follows：
1) the walking movement analysis of bluetooth equipments
First, three axles are obtained and accelerates data
1st, sample frequency is set：
(1) the limbs repeating motion of common people, each cycle is not over 200mS, so most fast motion frequency is 5Hz.
(2) it can be seen from sampling thheorem, when sample frequency fs is not less than 2 times of highest frequency fmax in signal, fs>=
Data signal after being sampled during 2fmax intactly remains the information in primary signal.
According to (1) (2) two conditions, this algorithm is in order to preferably reduce limb motion information, so using than most fast freight
Three axles are accelerated sensing acquisition xyz acceleration by use frequency 20Hz higher dynamic frequency 5Hz.
Sample frequency：Fs=20Hz (gathers an xyz axle acceleration per 50mS)
2nd, windowing obtains data and processing：
(1) forms length:
The general time is walked not over 1.5 seconds in view of common people, so the time width of forms is set as 1.5
Second.According to the sample frequency fs=20Hz (an xyz axle acceleration is gathered per 50mS) of this algorithm, therefore the forms of this algorithm are slow
Depositing length is：1500mS/50mS=30.
Window size：WIND_LEN=30；
(2) data filtering：
A. filtering principle
In order to obtain round and smooth meter step data curve, this algorithm is used：Recurrence average filter method (is also known as moving average filter
Method) the 3-axis acceleration data collected are filtered.(note：Recurrence average filter method principle：Continuously taking N number of sampled value
The length for regarding a queue as is fixed as N and samples a new data every time being put into tail of the queue, and throws away a number of original head of the queue
According to (first in first out), N number of data in queue are carried out arithmetic average computing, so that it may obtain new filter result.
B. code description：
This meter walks algorithm：N=4,
Average value is cached：AVERAGE_DATA[N]；
Freshly harvested xyz axles data：new_axis_converted；
Forms data is cached：axis_converted_avg[WIND_LEN]；
Average function：ADXL_AVERAGE(AVERAGE_DATA,4)；
LPF：Recurrence average filter method；
C. information contrast before and after filtering：Filtered data becomes rounder and more smooth, improves the precision of meter step
(3) maximin is sought：The various parameters for needing maximin to ask meter to walk in several steps.
Maximum structure：MAX_DATA{X,Y,Z}
Minimum value structure：MIN_DATA{X,Y,Z}
2nd, meter step algorithm
After the completion of windowing, start Data Post and several steps
1st, relevant parameter is sought：
(1) new threshold value (THRESH)：After the data acquisition for often completing a forms, threshold values is reacquired.New threshold value is many
The data of secondary forms are averaging.
(2) extreme difference value (DELTA)：Maximum subtracts the difference of minimum value.
DELTA=ADXL_MINUS (MAX_DATA, MIN_DATA)；
(3) broadband of threshold values half is worth：Subtract the poor difference for subtracting minimum value with new threshold value that new threshold value obtains with maximum to be compared, take big
Difference divided by wideband coefficients constant.
Wideband coefficients constant broadband=8.0, wideband coefficients constant (bigger broadband is narrower)
2nd, meter step：
(1) active degree of pedometer is judged：By judging whether the data maximums of each axle are more than new threshold value plus work
Jump constant, if greater than showing that pedometer has walking motion
Enliven constant：Brisk=0.3, (smaller sensitiveer)
(2) judge that axle is most active when first three axle accelerator：Compare three axle xyz pole absolute difference, extreme difference value is exhausted
It is the direction that walking is advanced to being worth very most active axle.
(3) judgement data is successively decreased direction：Subtract afterwards because the acceleration of a cycle of paces action first increases, this algorithm
With direction of successively decreasing as meter step operation.
(4) threshold values judges：Data, which are met, successively decreases, and to cross threshold values.
Judge whether number crosses the threshold values upper limit, obtain the data ceiling more than higher limit：
Judge whether number crosses lower threshold, yield less than the data floor of lower limit：
And the data ceiling more than higher limit is greater than data floor less than lower limit, and step number adds 1.
2) the walking data of mobile portable phones
First, mobile portable phone walking data acquisition flow
With mobile phone is placed on, when people's walking, by monitoring the acceleration transducer GSensor of mobile phone, acceleration is passed
Sensor can produce initial data, i.e. x, y, the acceleration magnitude of z-axis always.The incoming detection step after certain conversion
In detectorNewStep, wherein can judgment value whether be crest value, finally determine whether meter step.
3) sends the walking data result of bluetooth equipment to mobile phone
After pedometer and Bluetooth of mobile phone successful connection, start meter step algorithm.When pedometer and Bluetooth of mobile phone disconnect, close
Close meter step algorithm.So as to reduce pedometer power consumption.
Complete windowing gathered data and algorithm completes to calculate step number, pedometer is transferred to mobile phone by bluetooth approach.However,
The meter step and step number for often completing a forms are transmitted, and the time cycle is 1.5 seconds.Every 1.5 seconds of pedometer, by opening bluetooth garment
Business 0XFE22 passages transmit step number to mobile phone in an informed way.
4) carries out the contrast of the walking data of bluetooth equipment and mobile phone
In mobile phone, system can be to the walking data progress pair in the mobile phone of first 15 seconds with the respective generation of bluetooth equipment
Than being contrast unit with 1.5 seconds, the period for occurring walking movement is 1, and the period for walking movement do not occurred is
0, the uniformity of mobile phone and bluetooth equipment row step motion relatively more per second,
One, bluetooth equipments and mobile phone do not have walking movement situation；
If mobile phone did not had walking data (full 0) within 15 seconds, and bluetooth equipment did not had walking number within 15 seconds
According to (full 0), bluetooth equipment and the mobile phone situation without walking movement are represented.Because two objects are virtually free from leaving pair
Side, so not having situation about being lost, it is possible to judge that the alarm of anti-loss, as erroneous judgement, does not make alarm.
Two, bluetooth equipments do not have walking movement situation, but mobile phone has walking movement situation；
If bluetooth equipment did not had walking data (full 0) within 15 seconds, mobile phone had walking data and held within 15 seconds
It is continuous to be more than 3 seconds (result for occurring twice 1)), system can judge mobile phone belt with user, and bluetooth equipment is lost by user
Under, now application program of mobile phone is notified that user brings back bluetooth equipment.
Three, bluetooth equipments have walking movement situation, but mobile phone does not have walking movement situation；
If mobile phone did not had walking data (full 0) within 15 seconds, bluetooth equipment had walking data and held within 15 seconds
Continuous to be more than 3 seconds (result for occurring twice 1), system can judge mobile phone belt with user, and bluetooth equipment is left behind by user,
This situation can be determined as that bluetooth equipment is taken with oneself by user, and mobile phone is then left behind by user, and now bluetooth equipment can pass through buzzing
Device sends alarm, notifies user to bring back mobile phone.
Four, bluetooth equipments and mobile phone have walking movement situation；
If mobile phone and bluetooth equipment had walking data (both sides occurred 1 result), system within 15 seconds
It can be that chronomere is contrasted the walking data of the walking data of mobile phone and bluetooth equipment with every 1.5 seconds, check in the time
On uniformity.
In 15 seconds every 1.5 seconds once, can carry out 10 times contrast.
If both sides occur 1 (mobile phone and bluetooth equipment all singly close in the time and be detected simultaneously by step in section between at the same time
Row motion), it is as a result " consistent ".
If both sides occur 0 (mobile phone and bluetooth equipment are not all examined in the time single contract in section between at the same time
Survey walking), it is as a result " consistent ".
If anti-, so one of them is 0 (without walking) in same amount of time, and another is 1 (having walking), as a result for
