Program and the computer for running program.The computer of the operation program refers to the microprocessor or long-range in insertion fight ball
Any one or multinomial combination of server or the terminal using APP, webpage, wechat small routine.
Embodiment one, a kind of intelligence fight series of skills and tricks in boxing data correcting method based on acceleration.
The intelligence fight series of skills and tricks in boxing data correcting method based on acceleration of the present embodiment, as follows:
Judge to fight with whether ball training kicks off and kick off to correct: obtaining the detection of inertial navigation sensors current sample time
Ball acceleration information is fought with, judges to fight with whether ball is effectively struck and whether fought with before ball is effectively struck in weak static shape
State judges whether fight series of skills and tricks in boxing bat if so, obtaining the pressure data of pressure sensor detection on fight series of skills and tricks in boxing, if so,
Judgement kicks off to correct success, and fight ball training is kicked off, and otherwise determines that correction failure of kicking off, fight ball training are not kicked off, returns to step
It is rapid: to judge to fight with whether ball training kicks off and kick off to correct.
It is described judge to fight with ball whether referred to by effective impact and judge whether the acceleration information of fight ball is instantly increased value
By force threshold when greater than effective impact set in advance；The weak stationary state refers to that fight ball remains static or micro-
Weak swing state, fight ball acceleration value is approximately equal to 0 under the state.
It is described judge to fight with series of skills and tricks in boxing and whether bat refer to whether the pressure value of fight series of skills and tricks in boxing is greater than and set in advance effectively hit
It beats by force threshold.In the present embodiment, sampling time interval is 1 second, obtains the inertia being equipped with inside current sample time fight ball
The acceleration information of navigation sensor detection, acceleration tangential component an=160 meter/square seconds, n are sampling instant serial numbers.Root
Instantaneous acceleration setting instantaneous acceleration threshold value A=100 meter/square second brought by touching or colliding is deactivated according to fight ball,
Last moment acceleration tangential component an-1=0, weight coefficient k set in advance1=k2=1, then it calculates fight ball acceleration and cuts
Value Δ a is instantly increased to componentn=k1·an-k2·an-1=160 > A then determines that fighting with ball is effectively struck.When transferring current
The continuous N number of fight ball acceleration value detected before carving, N=5 set in advance are denoted as array p [N]=[0 0.01 0.04 0
0], the weak stationary state acceleration rate threshold P=0.05 meter/square second set in advance, the value in array p [N] is both less than P at this time,

Force data is 40 newton, determines fight series of skills and tricks in boxing batting, then determines to kick off to correct success, fight ball training is kicked off.
At the time of when record fight ball is effectively struck: record current time value is denoted as T0.In the present embodiment, when current
Quarter value is 8:20:30, i.e., value T at the time of when fight ball is effectively struck0=8:20:30.
Judge to fight with whether ball is struck and struck correction: obtaining fighting for inertial navigation sensors current sample time detection
Batting acceleration information judges to fight with whether ball is struck, if so, obtaining the pressure of pressure sensor detection on fight series of skills and tricks in boxing
Data, judge fight with series of skills and tricks in boxing whether bat, if so, determine batting correct successfully, enter step: judgement this strike whether be
It effectively receives, otherwise determines batting correction failure, determine that fight ball training at this time terminates；If current time fight ball is not hit
Beat, then enter step: judge to fight with after ball is effectively struck freely swing it is whether overtime.In the present embodiment, acquisition is currently adopted
The acceleration information of sample moment (current time 8:20:31) inertial navigation sensors detection, acceleration tangential component an=-5
Rice/square the second (contrary with striking), acceleration tangential component is instantly increased value Δ anIt=- 165 meter/square seconds, sets in advance
The instantaneous acceleration threshold value B=10 meter/square second that the fight ball set is struck, at this time Δ an< B, then determine fight with ball not by
Impact, enters step: judge to fight with after ball is effectively struck freely swing it is whether overtime.
Judge fight with ball effectively struck after freely swing whether time-out: record current time value, be denoted as T1, calculating fights
The time t that freely swings to bat after effectively being strucks=T1-T0；The time t that freely swings after ball is effectively struck is fought in judgements
Whether be greater than the timeout threshold T set in advance that freely swings, if so, determine fight ball effectively struck after when freely swinging
Between time-out, determine at this time fight ball training terminate；Otherwise determine that the time that freely swings after fight ball is effectively struck has not timed out,
Return step: judge to fight with whether ball is struck and struck correction.In the present embodiment, reads and record current time value T1=8:
20:31 calculates the time t that freely swings after fight ball is effectively strucks=T1-T0=1 second, it is set in advance freely swing it is super
When threshold value T=5 seconds, ts< T then determines that fighting with the time that freely swings after ball is effectively struck has not timed out, return step: judgement
Whether fight ball is struck and is struck correction.
Judging to fight with whether ball is struck and struck in correction, acquisition current sample time (current time 8:20:
32) acceleration information of inertial navigation sensors detection, acceleration tangential component an=120 meter/square seconds, acceleration tangentially divide

Whether this time whether impact is effectively to receive for judgement: being effective according to the current impact of fight ball acceleration information judgement
Whether fight spherical pendulum swings critical stationary state number less than 2 between impact and current impact and the last time fight series of skills and tricks in boxing batting,
If so, determining that this time impact is effectively receives, return step: at the time of when record fight ball is effectively struck, otherwise determine
This time impact is invalid impact, determines that fight ball training at this time terminates, terminates.
The fight spherical pendulum swings critical stationary state and refers to the fight ball moment static shape locating when swinging to highest point
State, the centripetal acceleration value that ball is fought under the state is 0.In the present embodiment, acceleration tangential component is instantly increased value Δ an=
125 > A=100 then determines this time impact for effectively impact；Read centripetal between this time impact and last effectively impact plus
Speed data totally 10, set A is constituted, the centripetal acceleration data that intermediate value is 0 have 1, i.e. fight spherical pendulum swings stationary state
Number m=1, m < 2 then determine that this time impact is effectively receives, return step: at the time of when record fight ball is effectively struck.
In step: at the time of when record fight ball is effectively struck, record current time value is that fight ball is effectively hit
Value T at the time of when beating0=8:20:32.
In step: judge to fight with whether ball is struck and struck in correction, acquisition current sample time (current time 8:
20:33) the acceleration information of inertial navigation sensors detection, acceleration tangential component an=140 meter/square seconds, acceleration are cut
Value Δ a is instantly increased to componentn=140-120=20 meter/square the second > B=10 meter/square second determines that fight ball is struck, obtains
The pressure data for taking pressure sensor detection on fight series of skills and tricks in boxing is 0 newton, determines that fight series of skills and tricks in boxing are not batted, then determines batting correction
Failure determines that fight ball training at this time terminates, terminates.
