One, the outdoor swimming state that the multidigit for having friend relation swimming user and lifeguard are worn is monitored into bracelet Identifier is deposited in the memory module of server；

Two, user presses after setting learns duration and learns button next time, into mode of learning, outdoor swimming state prison The 3-axis acceleration sensor and gyroscope surveyed in the sensor module of bracelet will constantly acquire the movement time series data of the user, And server, the number that server will receive are sent to for time series data is moved by communication control module and external communications equipment According to storing to memory module；Detailed process is as follows:

User presses study by setting button and the determining study duration of input key in display module after being provided with Button opens mode of learning；

Sensor module constantly acquired the exercise data of the user with Δ t seconds for sampling time interval, and each group of data are equal The acceleration information information in tri- directions x, y and z when including the user movement；In data acquisition, communication control mould is called Block simultaneously sends data to server by external communications equipment；Communication control module, for interval, sensor module was existed with S seconds S/ Δ t group data in S seconds are packaged, and are sent to server by external communications equipment and are stored to memory module；Wherein S is The integral multiple of Δ t；When study duration reaches duration set by swimmer, outdoor swimming state monitoring bracelet automatically exits from Habit mode；If user fulfils study ahead of schedule, mode of learning can be exited by consecutively pressing study button twice；

Preferably, in the outdoor swimming state monitoring bracelet, sensor module sampling time Δ t is preferably 0.2 second, is led to Believing control module packaged data and being sent to the interval S of server is preferably 2 seconds.

The outdoor swimming state monitoring collected one group of data of bracelet are represented by a_t=(a_xt,a_yt,a_zt)；Wherein a_tIt indicates In the acceleration of certain stroke of moment t, a_xt、a_yt、a_ztThe 3-axis acceleration sensor for being illustrated respectively in t moment certain stroke exists Output valve on three directions of x, y, z；

It indicates the data sequence for collecting user movement in learning process, may be expressed as:

Wherein n is natural number；

If user is abnormal event in certain time in the study stage, the data in the period are to it Judging whether user is in abnormality afterwards is very valuable information, therefore, is pulled outwardly when user passes through in the study stage The handle module on outdoor swimming state monitoring bracelet is opened, when issuing active distress signal, then it is assumed that user is now in exception State, communication control module record this moment t_uAnd by temporal information t_uDepositing for server is sent to by external communications equipment Store up module；

Three, the analysis module of server utilizes the number in Matlab software to the data collected in user's study stage It is fitted according to Fitting Toolbox cftool, and obtains the matched curve of time t Yu acceleration a, later again to the matched curve It is analyzed, concrete analysis process is as follows:

1, data acquired in the study stage are analyzed, obtains the minimum point in matched curve, it will be adjacent two-by-two Data between minimum point form data sequence, are clustered using hierarchical clustering method to data sequence is formed by, specifically Process is as follows:

(1) it regards each data sequence as a class first, K class can be obtained altogether, calculate every two using formula (1) The distance between class；

In formula (1), C_v、C_wTwo classes are represented, | C_v|、|C_w| respectively indicate class C_vAnd C_wThe number of interior data sequence, D (C_v, C_w) it is class C_vAnd C_wThe distance between,It is class C respectively_vAnd C_wSome interior data sequence, ForWithBetween DTW distance；

(2) two nearest classes of distance are found, judge whether termination condition (4) true, if so, then nonjoinder the two Class simultaneously terminates merging, goes to (5)；Otherwise, merge the two classes；

For any one class C_j(j=1,2 ..., K), degree of polymerization G (C in class_j) are as follows:

Wherein L_Cjp、L_CjqFor class C_jTwo interior data sequences, | C_j| it is class C_jThe number of interior data sequence；

If C_z∪C_hFor class C_zAnd C_hClass after merging takes class C_zAnd C_hIn class the average value of the sum of degree of polymerization come measure this two A class degree of polymerization in the class generated for merging class after merging, is denoted as μ (C_z,C_h)

It introduces parameter lambda (0≤λ≤1), termination condition is defined as:

(3) the distance between every two class is recalculated；

(4) (2) and (3) are repeated；

(5) after carrying out hierarchical clustering to data sequence, k (0 < k≤K) a class finally can be obtained, calculate each class Class in data sequence mean sequence, and using this mean sequence as such center sequence, i.e. class center；

2, judge whether receive the active distress signal of user's sending in the study stage, if received within the period actively Distress signal, then server determines the moment t that actively cries for help_uAnd its corresponding acceleration value a_uIt is formed by point (t_u, a_u), and Its corresponding position is determined in matched curve, while obtaining two minimum points adjacent with the point, intercepts the two minimum points Between data and by the data sequence marker be unusual sequences；For obtained k class, successively judge whether it includes that this is different Chang Xulie, if comprising being marked as exception class, otherwise, not marking；

3, after the study stage is formed by data sequence cluster, when the data sequence of certain classes in not labeled class Number is much larger than the data sequence number of other classes, i.e. data sequence non-equilibrium phenomena；The reason of causing this phenomenon has two aspects, First is that these data sequences are that user's proper motion data are formed, but since the learning time of user setting is shorter or data The reasons such as exception, which occurs, in transmission causes server such exercise data obtained less, second is that these data sequences are users What improper movement was formed, and these improper movements may cause the abnormality of user, and these improper movements occur Frequency be far below proper motion, thus accurately identify such exercise data and have important shadow for the judgement of user movement state It rings；Due to that can not judge that the data sequence of the class containing little data sequence is by user is normal or improper exercise data shape At, therefore these classes are first labeled as unknown class, determined later by analyzing the exercise data of exception monitoring phase user What whether the data sequence inside these unknown classes was formed by improper exercise data；The labeling method of class is as follows: calculating step 1 The average value and minimum value for the data sequence number for being included inside obtained not labeled each class, to obtained flat Mean value and minimum value are averaging again and using the threshold values of value kind judging as after；Its institute is successively judged to not labeled class Whether the number for the data sequence for including is less than threshold value, if being less than, is marked as unknown class；Otherwise, it is marked as just Normal class；

4, all class center sequences as the mode standard of user swimming stroke and are deposited into storage by server Module；

If four, learning time reaches the pre-set duration of user, outdoor swimming state monitoring bracelet will automatically exit from Habit mode, if learning time is not up to the pre-set duration of user, user can be exited by consecutively pressing study button twice Mode of learning fulfils study ahead of schedule；Hereafter outdoor swimming state monitoring bracelet will enter exception monitoring stage, outdoor swimming state The 3-axis acceleration sensor and gyroscope of sensor module in monitoring bracelet will continue the movement time series data of acquisition user, And server is sent to using external communications equipment periodically by communication control module；The when ordinal number that server will receive It is analyzed it according to preservation to memory module and by analysis module；Concrete analysis process is as follows: calculating the gained in step 3 The period of time T of the center sequence of each class arrived_iIn (i=1,2 ..., k) i.e. center sequence the last one data with first The time difference of data；If the center sequence cycle T of obtained k class_iIt is not identical, then sliding window technique is used, if Multiple sliding windows are set, the number of sliding window is equal to the number of class, and the length of i-th of sliding window is equal to T_i；By each window Mouth is placed on the initial position of time series, and length is T in each window corresponding sequence at this time_iA cross-talk sequence, then each Window moves back, then using second point of sequence as starting point, and forming another length is T_iSubsequence；The rest may be inferred, to Data of the family in time cycle S are analyzed, and each window is available altogetherA length is T_iSub- sequence Column calculate the STS distance of the center sequence of each subsequence and i-th of class, available altogetherA STS distance, and By wherein similarity measurement of the smallest STS distance as the time series and i-th of class；The rest may be inferred, it is available this when Between k class formed in sequence and step 3 similarity measurement, and the time series is included into minimum in similarity measurement In the corresponding class of value；If the class being included into is exception class, then it is assumed that the user is in abnormality, otherwise it is assumed that the user In normal condition；
