The specific embodiment:
Below in conjunction with accompanying drawing the present invention is done detailed description.
As shown in Figure 1, comprising: embedded controller 2, acceleration transducer 5, power supply, switch 1, display screen 4, power supply circuits 2; It is characterized in that: this control system is installed on sporter's the body, responds to the acceleration of motion of human body in X, Y, three directions of Z through acceleration transducer, and these three acceleration of gravity are outputed to controller;
According to the acceleration of motion of X, Y, three directions of Z, obtain the obliquity information of real-time said control system:
α=sin
-1(A
x/A
z)
3=sin
-1(A
y/A
z)
A
x, A
y, A
zRepresent the acceleration of gravity of X axle, Y axle, Z axle respectively, α representes the angle of inclination of X axle and Z axle, and β representes the angle of inclination of Y axle and Z axle.
Controller is according to preset obliquity information, and controller sends instruction.
Body sense control interface principle: utilize the mode Control-Menu of human motion to select,, select motor pattern, open or close pedometer etc. like choice menus; In order to realize this function, system uses a kind of inclination angle based on 3 acceleration of gravity sensor measuring systems.Acceleration transducer can be measured the acceleration of object in real time, if can access three axial acceleration of gravity then when object change athletic posture three axial acceleration of gravity also will change.Know that according to the vector formula more little its output of angle of closing acceleration of gravity direction and X, Y, three axles of Z is just big more, vice versa (as shown in Figure 3).The present invention extrapolates the inclination angle of X axle and Z axle and Y axle and Z axle through this principle, thereby the attitude information that solves equipment promptly tilts and front and back inclinations (pitching).The wearer just can come the switching menu option through pitch system like this.
Because system only need calculate relative inclination and change, so the wearer keeps steadily getting final product basically when the control system, need not to keep given pose (as shown in Figure 4).With wearer's system-oriented (13) B menu is example (11), if want to select the A menu (10) on the left side, only needs with system left-leaning (14), if want to select the C menu (12) on the right then to need system's Right deviation (15) certain angle.
In order to point out the position of the present menu of user, in the bottom of each menu a sign can be arranged all: wherein a kind of embodiment: become solid object like A menu leftmost side square frame (16); Square frame (17) in the middle of the B menu becomes solid object; C menu rightmost side square frame (18) becomes solid object.The user just can know clearly which pattern is system be in like this.
For robustness and the adaptive capacity that improves system.When the user with system during as for improper attitude, for example system is inverted, whether the user can manually provide one to be the control instruction that the user sends with reference to the inclination angle so that system determines this inclination angle more accurately.Acquisition with reference to the inclination angle has dual mode, and first kind of mode is called active correction and need not user's operation, and the second way is called by dynamic(al) correction and promptly needs human intervention.
Active correction need be set a time threshold and acceleration rate threshold, if in time threshold, repeatedly sample three axial acceleration of gravity, its value all remains within the acceleration rate threshold, then present absolute gravity accekeration is made as with reference to the inclination angle.That is, the axial inclination angle of current all that calculate is benchmark with this with reference to the inclination angle all.More simple by dynamic(al) correction, but need the wearer before operation, to push button, controller writes down the current acceleration value and immediately with inclination angle as a reference, its inclination angle that converses;
For prolongs standby time, select controller for use with low-power consumption mode.After system or power reset, controller is in running status.As stated, in order to realize different functions, the controller under the operation is understood constantly and peripheral system communicates, as lights display screen (4), reads three axial acceleration value from acceleration transducer.When controller need not move, can utilize a plurality of low-power consumption modes to save power consumption, the present invention adopts three kinds of modes to make system get into low-power consumption mode: first kind of mode is the most direct, promptly belongs to passive mode through sleep switch control; Second kind is passed through system reverse is placed the entering low-power consumption, belongs to a kind of passive mode equally; The third initiatively gets into low-power consumption through predefined acceleration standby threshold.Except that first kind of mode need add the button, back dual mode only needs existing acceleration transducer of multiplexing native system or same function device to realize.
First kind of mode (as shown in Figure 5) at first is described, this mode is through a selector switch (19) be connected with controller (22).Controller is under control of software, and polling mode checks whether this pin is designated as resting state, if being found to be resting state (21) then gets into low-power consumption mode immediately, and closes peripheral hardware: display, sensor; Waking up of this sleep mode needs the user that selector switch is dialled the capable state (20) that backhauls again.
Second kind of mode that gets into dormancy needs the acceleration transducer real-time monitoring system whether to get into a specific expectation state (like Fig. 6, shown in 7).An instance is: select when the Z axle acceleration of gravity that monitors less than 0 and X and two axial acceleration of Y entering park mode when equaling 0.Consider the movable naturally influence that environmental factor and human body are slight, three axial values are similar to that (X=0, Y=0 Z=-1) get final product.Wake then from park mode that (X=0, Y=0 Z=1) get final product as long as satisfy up.
The third mode that gets into dormancy needs the data of acceleration transducer.At first, need preestablish the desired value of a sensor, i.e. 3 axial accekerations.Check at interval with certain hour whether acceleration transducer can read this value afterwards, because environmental factor, system will allow deviation within the specific limits, and promptly three axial accekerations satisfy certain scope and get final product, and a kind of mode was more flexible before this mode compared.In order to prevent misoperation, need inquire about repeatedly more than twice,, acceleration gets into low-power consumption after repeatedly satisfying automatically.The waking up of this dormancy can be adopted the system of rocking and removed.
It should be noted that; The numerical value of the real-time acceleration of gravity sensor that the mode two that entering wakes up and mode three are required need not controller and reads specially; System's required data when accomplishing normal function can be tried to achieve; For example with in the amount of exercise detection packet that correlation function read back promptly comprise X, Y, three axial accekerations of Z, can obtain the instruction that whether need get into park mode through the said principle of Fig. 3.
The another one function that native system has is: through body sense option date and the same day of checking motion conditions.The motion conditions statistics that the user need check through the selection of calendar menu; The user not only can know the amount of exercise data statistics in one section official hour, but also can combine hand motion to select to browse certain day archive data automatically through the calendar menu.These archive data comprise: the same day move distance, run duration consumes calorie, pedometer numerical value, maximum speed.
Activity description in the past any given day, activity intensity and mean activity situation weekly all will be presented in the display, and the mode of selecting to check the date will realize by means of the inclination of hand.
At first, System menu need be adjusted to the date and check state.Date checks that the interface arranges according to the monthly calendar mode: i.e. every page of whole dates that show current month.Every row is according to week order arrangement (for example: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday).
Check the file that also will include in the interface on the date about motion conditions; These data comprise: the distance of running the same day, total run duration, average speed, maximum speed, consumption calory count, pedometer numerical value, and the gap between amount of exercise and the amount of exercise desired value.
For the ease of according to the date index, native system has two kinds of preference patterns: first kind for by key index, and this method is accomplished the selection of upper and lower, left and right four direction through the external button of system; Second kind is body sense index, and this mode tilts to control the selected date through the user to different orientation.
No matter use which kind of mode, when the selected date has been in the fringe region of this month calendar, then can jump to adjacent date in adjacent month if still move the selected date to edge direction.An embodiment of this function: current month is March, then can get into February if (or making progress) is mobile left, and (or downwards) moves and then get into menu in April to the right.
Another function of the present invention is: through network more detailed movement analysis and stores service are provided, these services comprise: move distance, and run duration consumes calorie, pedometer numerical value, motion speed per hour; Native system can be sent to the webserver with data through USB, wireless or other transmission mediums.
Server is with the move distance of collecting, run duration, consumption calorie, pedometer numerical value, movement velocity record; And through Principle of Statistics be plotted as curve map or other can characterize motion drive to form; And be simultaneously displayed in the webpage with wearer's motion expectation curve; Remind the user to adjust motor behavior according to this, promptly shorten or prolong amount of exercise, run duration, exercise intensity and motion kind.
