(embodiment 1)
Embodiments of the invention 1 have exemplified a kind of body motion detection device, and 2 body action pick offs that the mode that this device detects in order to the body action to orthogonal 2 directions disposes calculate walking, use accompanying drawing that embodiment 1 is described below.
The structure of the body motion detection device of embodiment 1 at first, is described according to Fig. 1 and Fig. 2.Fig. 1 is an outward appearance front view of representing to carry with certain angle of inclination the body motion detection device state, and this body motion detection device is built-in with described 2 body action pick offs, and Fig. 2 is a circuit block diagram.
In embodiment 1, body motion detection device 1 is provided with input equipment 2 and display device 3 in its front, and portion is provided with described 2 body action pick offs 4 within it, also has amplifier 5,6, A/D converter 7,8, storage device 9 and CPU10.
Described input equipment 2 is in order to import various settings, to measure and to begin and termination etc. and being provided with, and described display device is used for showing various guiding or measurement result etc.In addition, as shown in Figure 1, described body action pick off 4 is by constituting at X-axis body action pick off 4a that has sensitivity on the X-direction and the Y-axis body action pick off 4b that has sensitivity on Y direction, and it takes to comprise the body action signal of the acceleration of gravity composition relevant with each direction of principal axis with certain sampling period.At this, in the present embodiment, the testee with respect to vertical direction and horizontal direction, is installed in described body motion detection device 1 on belt etc. according to angle of inclination shown in Figure 1, is mounted to formed plane of X-axis and Y-axis and vertical direction and installs abreast.
Described storage device 9 comprises: be used for storing the X-axis buffer 9a of the signal of described X-axis body action pick off 4a, be used for storing the Y-axis buffer 9b of the signal of described Y-axis body action pick off 4b equally.
In addition, described X-axis body action pick off 4a is connected with CPU10 by amplifier 5 and A/D converter 7, equally, described body action pick off 4b is connected with CPU10 by amplifier 6 and A/D converter 8, is that digital signal is transported to CPU10 with described body action pick off 4a and the detected analog signal conversion of 4b.Described CPU10 has body action output arithmetic unit, synthetic output arithmetic unit, body action counting assembly and decision maker.
With reference to Fig. 3 to Fig. 9, body action signal and described each arithmetic unit that is detected by described each body action pick off 4a and 4b described simultaneously.Fig. 3 and Fig. 4 represent by X-axis and Y-axis body action pick off 4a and 4b detected respectively, the time dependent waveform of each body action signal during walking, Fig. 5 is that expression is detected by described X-axis and Y-axis body action pick off 4a and 4b, body action is the time dependent waveform of each body action signal under the big situation when running etc., to be expression deduct behind the predefined bias voltage value and each body action that obtains is exported time dependent waveform from described each the body action signal shown in Fig. 5 Fig. 6, and Fig. 7 is the time dependent waveform of synthetic output that expression obtains by synthetic described each body action output valve.
At first when detecting described body action signal, when the such body action with constant rhythm of walking being done detection, as shown in Figures 3 and 4, described X-axis body action pick off 4a and Y-axis body action pick off 4b detected each body action signal AxO and AyO, along with the time change and form the such signal waveform of diagram.
Described each body action signal is to preestablish under the state of bias voltage in described X-axis body action pick off 4a and Y-axis body action pick off 4b, body action vibration (dynamic acceleration) under the influence of the acceleration of gravity that acts on X-direction and the Y direction detects to being subjected to, promptly, to be output as datum line along the acceleration of gravity that is subjected on each direction of principal axis, thereby form the described dynamic acceleration such waveform of amplitude along the vertical direction, for example, in Fig. 3 and Fig. 4, as the interval between upper limit peak value and the lower limit peak value (hereinafter referred to as the P-P interval) expression be the regulation interval, the meansigma methods in this regulation interval is represented to be subjected to acceleration of gravity component X G and YG along described each direction of principal axis.Promptly, even under the situation that does not produce described dynamic acceleration, and when on described X-axis body action pick off 4a does not detect the horizontal direction of acceleration of gravity composition, having sensitivity, also exportable described bias voltage value AO, when as the detection side to X-axis when tilting than horizontal direction, X-axis body action pick off 4a also can detect the acceleration of gravity XG that is acted on described incline direction.For Y-axis pick off 4b, situation is also identical.
So, remain static down at body motion detection device 1, the sensitive direction of described X-axis body action pick off 4a is in horizontal direction and does not detect under the situation of acceleration of gravity composition, output valve with this moment, be that described bias voltage value is taken as AO, the bias voltage value of same Y-axis body action pick off 4b also is AO, and Fig. 5 is when being illustrated in the people and running, each body action signal AxO of X-axis and Y direction and the time dependent figure of AyO.
Described body action output arithmetic unit, after deducting described bias voltage value AO with body action pick off 4a and Y-axis with detected each body action signal AxO of body action pick off 4b and AyO from described X-axis, and with this result's output, Fig. 6 be expression with described output as X-axis and Y-axis each body action output Ax1 and during Ay1, this exports time dependent figure.At this moment, described Ax1 and Ay1 are illustrated in the composition of the acceleration of gravity that is subjected on each direction of principal axis, also represent detected dynamic acceleration simultaneously.
Described synthetic output arithmetic unit, be used for the synthetic output A1 of the body action output Ay1 of the body action of X-axis output Ax1 and Y-axis is carried out computing, synthetic output A1 is used for calculating the resultant vector of orthogonal 2 axles, and calculates with arithmetic expression A1=(Ax12+Ay12) 1/2.That is: can obtain in the size that is subjected to the synthetic dynamic acceleration under the environment that acceleration of gravity is 1G, thereby obtain the synthetic output waveform shown in Fig. 7.
Described body action counting assembly adopts described synthetic output A1 to come step number is counted, for example, as shown in Figure 7, described synthetic output A1 reaches the threshold value of predefined regulation or more than it, reduce to described threshold value then again again when following, then once count.
In addition, below simultaneously with reference to Fig. 8 and Fig. 9, described decision maker is described.Fig. 8 is that each body action that expression is exported according to the judgement that described decision maker carried out is exported time dependent waveform, and Fig. 9 is the expression time dependent waveform of synthetic output that output is synthesized into to the body action after the described judgement.
From the arithmetic expression of described A1 as can be known, the synthetic output A1 shown in described Fig. 7 is positive output.That is: shown in the circle D portion among Fig. 7, in the waveform of synthetic output A1, be formed with following waveform, that is: the output of extreme value that should be protruding downwards is from being output as 0 (V), turns back and becomes positive output with symmetric mode.Why produce this situation, its reason is: illustrate with Fig. 5, as mentioned above, in X-axis body action pick off 4a and Y-axis body action pick off 4b, because dynamic acceleration is the datum line up-down vibration with the acceleration of gravity composition, so sometimes body action signal AxO and AyO the waveform that forms respectively, can be along with the change of dynamic acceleration big and intersect with bias voltage value AO, so this cross section just becomes the output of turning back shown in the circle D portion among described Fig. 7.
As shown in Figure 7, in the waveform of the synthetic output A1 with the output of turning back, along with the change of dynamic acceleration is big, the described output valve of turning back also can become greatly, so, in described body action counting assembly, judge the difficulty that will become with threshold value sometimes.
Therefore, in described synthetic output computing, in order not export the described output of turning back, so allow the symbol of described each body action output Ax1 and Ay1 and the meansigma methods XG in the described P-P interval that described each body action is exported Ax1 and Ay1 and plus sign or the minus symbol of YG compare, when both symbol not simultaneously, judge that then this output is unsuitable for synthesizing, and this body action output valve is converted into zero, and when both symbol is identical, just directly be judged to be Ax1 and Ay1, and the output of the body action of described judgement exported as Ax1=Ax2 and Ay1=Ay2, so shown in the curve chart of Fig. 8, can obtain the waveform that forms by body action output Ax2 and Ay2.
In addition, by described synthetic output arithmetic unit, the body action output Ax2 of described judgement and the synthetic output A2 of Ay2 are carried out computing, thereby can obtain the synthetic output waveform shown in Fig. 9.
Below, use Figure 10 to Figure 12 that the action of the body motion detection device 1 of present embodiment is described.Figure 10 is the flow chart of the mastery routine of the action of body motion detection device in the expression present embodiment, and Figure 11 represents to carry out the subprogram of body action output determination processing, and Figure 12 represents to count the subprogram of step processing.
At first, in the mastery routine of Figure 10, when measuring beginning by input equipment 2 inputs, the power supply of body motion detection device 1 is switched on, so carry out the initial setting of device in step S1.In step S2, in X-axis body action pick off 4a and Y-axis body action pick off 4b, detect the body action signal AxO and the AyO of each the direction of principal axis composition that comprises acceleration of gravity respectively, this body action signal AxO and AyO are respectively through amplifier 5 and 6, and A/D converter 7 and 8, taked among the CPU10 as numerical data, so form the waveform shown in Fig. 5.
In step S3, calculate the body action signal AxO of described sampling and the difference between AyO and the described bias voltage value AO, so obtain described body action output Ax1 and Ay1 respectively, and be stored in respectively among X-axis usefulness buffer 9a and the Y-axis usefulness buffer 9b, form waveform as shown in Figure 6.
In step S4, judge whether it is the sampling that in the interval of regulation, obtains described body action pick off 4a and body action pick off 4b.Described regulation interval is meant, the interval in (P-P interval) between described each the body action pick off 4a in embodiment 1 and time dependent upper limit peak value of 4b and the lower limit peak value, and at the interval obtained number of samples of described P-P be: n=1 is to nmax.That is: when being stored in X-axis respectively when not reaching nmax with the number of Ax1 among the buffer 9b and Ay1 with buffer 9a and Y-axis, then carry out NO, and when continuing sampling among the step S2 and obtain nmax sampling, then carry out YES, in following step S5, calculate described nmax body action output Ax1 and each meansigma methods of Ay1, they are stored in the described memorizer 9.As described, the meansigma methods in described each P-P interval is represented the component (XG and YG) of the acceleration of gravity that is subjected on each.
In step S6, since read respectively successively described X-axis with buffer 9a and Y-axis with buffer 9b in the n=1 sampled data of storing in the described buffer address of nmax, institute is so that the buffer address turns back to n=0, in following step S7, the buffer address counted successively as n=n+1 finish, and read in the sampled data in the P-P interval of the body action output waveform that forms X-axis and Y-axis one by one.
The body action output determination processing of step S8 is performed such, though that is: will use Figure 11 to describe in the back, by the decision maker in the CPU10, the symbol of the meansigma methods in the P-P interval of described each body action output and the symbol of n body action output valve are compared, when symbol not simultaneously, just described n body action output valve converted to zero, so as shown in Figure 8, the body action output Ax2 and the Ay2 that obtain judging.Thus, as mentioned above, can when exporting, synthetic body action not form the output of turning back.
In step S9, synthesize described n body action output Ax2 and Ay2 by the synthetic output arithmetic unit in the described CPU, thereby obtain the synthetic output A2 shown in Fig. 9.Described synthetic output A2 utilizes formula A2=(Ax2
2+ Ay2
2)
1/2Come computing.In following step S10, according to described synthetic output A2, by using the body action counting assembly in the described CPU10 that Figure 12 illustrates in the back, the meter step of application of known handles and detects step number.
In following step S11, with respect to whole sampled data in P-P interval, judge and whether carried out described step S7 promptly judge whether reached n=nmax to step S10.When not reaching, carry out NO, and, carry out described handling procedure repeatedly, when reaching n=nmax, carry out YES, and then turn back to step S1 with respect to following sampled data according to n=n+1, transfer to next P-P interval processing.
Herein, utilize Figure 11 that the body action output determination processing of described step S8 is specifically described.In step S21, read n body action output Ax1 that is stored in the described storage device 9 and Ay1, with each the meansigma methods in P-P interval.Among the step S22 below, the symbol of described each meansigma methods and the symbol of each body action output Ax1 and Ay1 are compared, under the identical situation of symbol, owing to when compose operation, can not export the output of turning back, therefore carry out YES, in step S24, with described body action output Ax1 and Ay1 as judging whether suitable body action is exported Ax2 and Ay2, X-axis is upgraded with the storage of buffer 9b with buffer 9a and Y-axis, turned back to then in the mastery routine of Figure 10.In addition, under the different situation of symbol, carry out NO, in order not export the output of turning back when the synthetic output computing, and the value itself of each body action output Ax1 and Ay1 is replaced as zero, be stored in X-axis more respectively and use among the buffer 9b with buffer 9a and Y-axis.Be described body action output Ax2 and all vanishing of Ay2, turn back to the mastery routine of Figure 10.
In addition, utilizing Figure 12 that the meter step of described step S10 is handled is specifically described.This meter step handles and preestablishes threshold value, and this threshold value can judge the described synthetic output A2 that enough is used for detecting step number, when greater than described threshold value, from detecting the state of the described synthetic A2 of output, when being lower than described threshold value, the counting to step number is finished.
That is, after calculating described synthetic output A2, the meter step that moves to Figure 12 handles, and will judge in step S31, judges whether to be provided with the described synthetic output A2 of expression greater than being used to differentiate the labelling 1 that is enough to the threshold value that detects as step number.Under the situation that labelling 1 is not set, then be judged to be the synthetic output A that does not detect greater than described threshold value, then carry out NO, and in step S32, whether the described synthetic output A2 that calculates is judged greater than described threshold value.If not greater than described threshold value, then carry out NO, and directly turn back in the mastery routine of Figure 10, if greater than described threshold value, then carry out YES, in step S33, after being provided with described labelling 1, turn back to the mastery routine of Figure 10 again.
In addition, in described step S31, under the situation that labelling 1 is being installed, promptly judge the state that has detected greater than the synthetic output A2 of described threshold value that is in, so carry out YES, in described step S34, judge whether described synthetic output A2 is less than described threshold value.When greater than described threshold value, then carry out NO, in step S35, as mentioned above step number is added, and the result is stored in the memorizer 9.
(embodiment 2)

In addition, in the decision maker of CPU10, carried out making that unwanted the turning back of step number counting is output as zero processing among the represented synthetic output A1 of in Fig. 7 circle D portion, but in fact, in an embodiment, counting in the general step count set of step number according to the threshold value that the output that can detect step number is judged, when described size of turning back output can have influence on the judgement of being undertaken by described threshold value, the walking of output this moment and running etc. all is difficult to judge, can make its correspondence by setting threshold suitably, as for walking, be that amplitude is in the reciprocating motion of counting cm up and down, compare with acceleration of gravity, its dynamic acceleration changes extremely little, and the described output of turning back itself is output hardly.At this moment, also can not need described decision maker.
In addition, in the step S122 of the step S22 of Figure 11 and Figure 14, the decision maker of CPU10 is exported each P-P interval of Ax1 and Ay1 as the regulation interval with body action, and judge the compose operation that whether is suitable for of described body action output Ax1 and Ay1 according to the meansigma methods in described P-P interval, but described regulation interval also is not limited to the P-P interval, also can be the interval of datum line symbol that can judge the track waveform of each body action output.Though obtained the meansigma methods in P-P interval, also can carry out the judgement whether described computing is fit to according to the midrange of upper limit peak value in the described regulation interval and lower limit peak value.
In addition, described counting assembly is to count step number according to described synthetic output A1 or A2, but, described synthetic output A1 and A2 are the sizes of the dynamic acceleration in being illustrated under the environment that is subjected to acceleration of gravity 1G, for example also has the dynamic acceleration arithmetic unit, it is by calculating the difference between the output that described synthetic output A1 or A2 and predefined acceleration of gravity are the 1G size, under the influence of eliminating acceleration of gravity, calculate the size (dynamic acceleration) of body action, so also can be applied on the device of organism being measured according to described dynamic acceleration.Described acceleration of gravity is that the output of 1G size can be respectively the meansigma methods or the mid point in the regulation interval of synthetic output A1 or A2, also can be the meansigma methods in regulation interval of each body action output or the synthetic output of mid point.
In addition, as shown in Figure 2, when X-axis body action pick off 4a and Y-axis body action pick off 4b obtain body action signal AxO and AyO respectively, through amplifier 5 and 6, and A/D converter 7 and 8 obtain, however, but, also can between described each body action pick off 4a, 4b and described amplifier 5,6, common analog filters be set, to obtain described body action signal AxO and AyO in order to remove noise from each body action pick off 4a and 4b.
