Abstract

PROBLEM TO BE SOLVED: To provide a health promotion system which can be used even at the warming-up time and cooling-down time of a user and does not cause such a failure that the pulse of the user is not stabilized due to the individual difference of the user in the responsiveness of a change in pulse rate to a change in quantity of motion even when the system adjusts the pulse rate of the user by adjusting the quantity of motion of the user by making faster or slower the tempo of motion outputted from a built-in oscillator based on the difference between the pulse rate and target pulse rate of the user as the conventional health promotion system does. SOLUTION: This health promotion system is provided with a motion step sensor 31 which detects the tempo of the present motion of the user, a first correcting means 38 which corrects the tempo outputted from the sensor 31 based on the difference between the pulse rate HB (t) and target pulse rate HBd (t) of the user, and a tempo outputting means 42 which outputs the corrected tempo as a tempo command signal. Since the basis of the tempo is the tempo of motion of the user itself, more suitable stable pulse rate control to the health promotion of the user becomes possible.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention supports walking, jogging, and other rhythmic exercises as exercises.
The present invention relates to improvement of a health appliance for enhancing body fat burning efficiency and exercising healthily, happily, and safely.

[0002]

2. Description of the Related Art Many people, irrespective of whether they are sportsmen or not, maintain or improve their health, such as walking, jogging, treadmill exercises, steppers, and skywalkers performed indoors. Doing exercise. In the case of sports professionals, there are specialists (coaches or instructors) who have acquired health management skills in sports gyms, etc., but amateurs, children, and the general public who can not be called sportsmen personally If you exercise around your home, you have no choice but to manage yourself. And often, accidents are reported that can only be attributed to sudden or extreme exercise, and the need to manage the level of exercise for health promotion is highlighted.

[0003] However, the health condition of a person depends on the physical condition of the day,
In addition to being affected by the mental state, it is also affected by outdoor environmental changes such as temperature and humidity, the presence of sunshine and wind, so it is important to determine how much exercise is useful for promoting health and how dangerous it is It is very difficult for amateurs. As an example of a health promotion system invented from such a viewpoint, a device as a running pacemaker disclosed in Japanese Patent Application Laid-Open No. 61-953 is shown in FIGS.
Shown in This allows the user to easily take a fixed pace that is set in advance, and also measures the pulse and automatically lowers or lowers the pace if this exceeds a predetermined upper limit or falls below a predetermined lower limit. Raised, so that you can always exercise safely.

FIG. 11 is a block diagram of the electric circuit, and FIG.
2 is a diagram showing an appearance and a use state. In the figure,
1 is a main body of a running pacemaker, 2 is a pace signal generating means (variable frequency oscillation circuit) for generating a pace signal at a set speed, and 3 is a pace instructing means for notifying the pace signal as a sound from a speaker 24 or by displaying it. is there. Reference numeral 4 denotes a detector 6 attached to the body as pulse detecting means and an amplifier 7 for amplifying the signal. The display means 5 comprises a counting means 14 for counting either the pulse rate detected by the pulse detecting means 4 or the pace signal, and a display means 15 for displaying the counted value.

Reference numeral 17 denotes a pulse rate setting means, and reference numeral 18 denotes a pulse comparison means (digital comparator) which compares the set reference pulse rate with the detected pulse rate and outputs an output signal corresponding to a deviation between the two. . The pulse rate setting means 17 includes a pulse lower limit value setting dial 21 and a pulse upper limit value setting dial 22.

Next, the operation and usage will be described. Power on
OFF and other explanations that seem to be natural or too detailed in terms of operation principle are omitted. Before starting the running, the pacemaker 1 was attached to the wrist as shown in FIG.
Put 0 on your finger. With this, the pulse rate is measured and displayed.
The user sees this and checks and confirms his / her health condition. Next, the pulse lower limit value setting dial 21 and the pulse upper limit value setting dial 22 are operated to set the upper and lower limits of the allowable pulse rate based on the physical condition of the person. Next, when a desired pace is set in the pace signal generating means 2, the speaker 24
, So that the pace sound like pi, pi…
Just run along with this.

If the pulse rate exceeds the upper limit while the vehicle is running, the output of the pulse comparing means 18 causes the output pace of the pace signal generating means 2 to decrease. When the pulse rate falls below the lower limit during running, the output pace of the pace signal generating means 2 is increased by the output of the pulse comparing means 18 and the output pace is controlled so as to approach the set pulse rate. The momentum is controlled.

As described above, the running pacemaker is useful for maintaining a constant pace of exercise in a steady state. However, as is well known, in exercise, it is better to perform a preparatory exercise before and after the start of exercise, and to slowly start and end the exercise than to manage the steady-state momentum. is important. Accidents such as cardiac paralysis during exercise often occur when the physical load suddenly changes immediately after the start or end of exercise.However, the above-described conventional device configuration can cope with the above-mentioned transition. There is a fundamental problem that there is no.

[0009]

Since the conventional health promotion system is configured as described above, there are the following problems. 1) Since only the pulse rate of the user is detected, the control is delayed and an overload pace is easily generated, which is not preferable for health. In addition, the pulse rate is not stabilized at a steady value for some people even if they exercise at the indicated pace. 2) Since load changes based on environmental changes such as uphills, downhills, headwinds, and tailwinds are measured only by changes in the pulse rate, the control is easily delayed and the pace and the pulse rate are difficult to stabilize.

3) At the start of exercise and at the transition of exercise change at the end of exercise, it is necessary to instruct a change in pace necessary for health corresponding to warm-up and cool-down such that exercise is gradually increased and gradually decreased. Can not. 4) For a first-time user, it is impossible to know the appropriate pace of exercise unless the user uses it several times and sees the result, and the user is used in a dangerous use state until then. There is fear. 5) The use effect is low only after the motion enters the steady state, and the use efficiency is low. 6) The pace signal is only a sound or a display, but the sound is annoying to the accompanying traveling person. On the other hand, the display is difficult to see while running, so that the means for transmitting the pace signal is not appropriate.

The present invention has been made to solve the above problems, and has as its object to provide a health promotion system capable of controlling a pulse rate extremely stably. It is another object of the present invention to provide a health promotion system in which a delay in following control is reduced. It is another object of the present invention to provide a health promotion system capable of instructing a pace change necessary for health corresponding to warm-up and cool-down. It is another object of the present invention to provide a health promotion system in which a first-time user is not at risk of being used in a dangerous use state even if he or she does not know the appropriate exercise pace. In addition, it can be used usefully, even during the momentum transition from before the start to after the end of the exercise,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an outline of the exercise enhancement system of the present invention will be described. A pulse of a user is detected, and the final output is sound or vibration.
..When the tempo command signal is output and the user exercises based on the tempo command signal, the pulse from the start of exercise to the end of exercise and at the end of exercise draws an ideal curve. However, at that time, by picking up the tempo of the user's exercise (as a change in body acceleration, etc.), controlling its frequency or phase, and outputting it as a tempo command signal, the tempo is made more suitable for health promotion. It controls the command signal. To facilitate understanding, “tempo”, “tempo of user's exercise”, “tempo signal”, “tempo command signal” used in the following description
Is defined as follows. "Tempo" = the number of stimuli per unit time, also called speed as customary. “User's exercise tempo” = the number of exercises per unit time of exercise. “Tempo signal” = an electric signal representing the above tempo as numerical data. In order to make it clear that the data is data, it may be described as "number of tempos". "Tempo command signal" = pulsation transmitted to a person. Popping sound or vibration, flashing light, etc.

And also
FIG. 4 is a timing chart for explaining the operation of FIG.
Shown in In FIG. 1, reference numeral 30 denotes a central processing unit (hereinafter referred to as a CPU) of the health promotion system, to which all devices and means described below are connected via a bus 45. An exercise step sensor 31 is attached to, for example, the user's waist, arms, or legs, and picks up by an acceleration sensor or the like that incorporates an exercise step signal (timing signal) synchronized with vertical movement or vibration due to exercise, and a tempo calculation circuit. The exercise tempo is calculated by 31a. A pulse sensor 32 is mounted on a human earlobe, arm, finger, or the like, picks up a timing signal synchronized with the pulse by a known technique, and calculates a pulse rate by a pulse rate calculation circuit 32a.

An input device 33 includes a plurality of keys or push buttons and an interface (not shown). Reference numeral 34 denotes a display device, which is constituted by, for example, a color or monochrome liquid crystal screen capable of character display or graphic display. The input device 33 and the display device 34 may be integrated. 35 is a use condition input means for inputting, for example, the intensity of the exercise to be started here, or the intensity of the exercise, the type, the expected duration, the sex of the user, the age, the pulse rate at rest, etc. This may be performed by the input device 33).

Numeral 36 denotes a target pulse rate / time function generating means which uses the pulse rate change pattern (target pulse rate / time function) which is ideally input from the start of exercise to the end of exercise by the user. Create and output based on conditions. Although not shown, a reference clock is built in. Reference numeral 38 denotes first correction means for performing correction, which will be described later, on the user's exercise tempo which is detected and output by the exercise step sensor 31.
Reference numeral 40 denotes an environmental condition input means for inputting the current environmental conditions of the place where the exercise is performed, for example, the degree of sunshine, presence or absence of wind, temperature, humidity, and the like from the input device 33. Environmental sensor 4 including temperature and humidity sensor
It may be automatically imported from 1. Reference numeral 42 denotes a tempo output means which outputs the corrected tempo signal as a tempo command signal in a form which can be recognized by the user, for example, sound, flash light, vibration, etc. 43 denotes a sound generator (earphone) described as an example for convenience of explanation. ).

Reference numeral 44 denotes a memory (specifically, a flash memory, for example) connected to the bus 45.
S, input conditions, and the like are stored. Reference numeral 100 denotes a drip-proof case which is a main body of the health promotion system. What is described on the outside of the main body portion 100 is mounted on the body or clothing of the user, and is connected to the main body by a lead wire or wireless transmission means (not shown). Although a power source is necessary, it is not shown. The use state explanatory diagram of FIG. 2 will be described. FIG. 2 shows a jogging state outdoors as an example of exercise. The main body 100 of the health promotion system, the exercise step sensor 31 are attached to the waist band, and the sounder (earphone) 43 and the pulse sensor 32 are attached to the ear. .

Next, the operation will be described with reference to the functional circuit diagram of FIG. 3 for explaining the operation. First, for example, the following items are input from the use condition input means 35 (using the input device 33), or selected from items registered in advance. a) intensity of exercise to start here, (type or intensity of exercise desired) eg "walking", "jogging", "skywalker" or any other type, fast, slow,
The degree of exercise, such as normal. b) The expected duration of this exercise, for example, 1 hour or 3 hours. c) Gender of the user. d) Age. e) Pulse rate at rest. At least temperature, humidity, and the like are input from the environment sensor 41.

The target pulse rate time function generating means 36 creates a time change pattern of the pulse rate from the exercise start time to the end time of the target pulse rate of the user based on the above input items, It generates an output HBd (t) (FIG. 4a) that varies with elapsed time after a start signal input by the user. When the temperature and humidity are not appropriate, the output is designed so that the burden is not too heavy. Exercise step sensor 3
1 detects the movement step of the user as a pulse signal,
Based on this, the tempo calculation circuit 31a calculates the exercise tempo W
h (t) is calculated (FIG. 4b). Next, the pulse sensor 3
2 and the pulse rate H obtained by the pulse rate calculating circuit 32a.
The difference between B (t) (FIG. 4c) and the target pulse rate HBd (t) HBd (t) −HB (t) = ΔHB (t) (FIG. 4d) is calculated by the circuit 36b.

The correction value required to correct the tempo in the direction in which the pulse rate difference ΔHB (t) becomes zero is ΔH
It is calculated by the circuit 36c using the following correction formula for multiplying B (t) by a predetermined coefficient (KHB) (FIG. 4e). Correction value = KHB · (HBd (t) −HB (t)) (1) And this correction value is the tempo Wh of the exercise of the user.
(T) and corrected tempo command signal Wm
(T) is output (FIG. 4f) (this is referred to as a first correction). That is, Wm (t) = Wh (t) + KHB · [HBd (t) −HB (t)] (2) The determined output tempo Wm (t) is, for example, a predetermined tempo command signal of the sound source circuit. Po, po, po ...
It is output as a sound like

Embodiment 2 FIG. 5 shows a functional circuit diagram of the second embodiment. In the functional circuit diagram of FIG. 3 of the first embodiment,
The first correction 38 corrects the tempo of the tempo command signal based on the difference between the target pulse rate and the current pulse rate.
In the second embodiment, the phase of the tempo command signal output by the second correction means 39 is corrected based on the difference between the target pulse rate and the current pulse rate. That is, when the phase of each signal is represented by Φ, the control amount of the phase of the tempo command signal based on the difference between the target pulse rate and the current pulse rate is calculated by the phase shift amount conversion circuit 36d of the exercise tempo as ΔΦ = AHB · [ HBd (t) -H
B (t)]. AHB is a coefficient for converting a pulse rate difference into a phase difference.

On the other hand, the phase Δh (t) of the user's exercise detected by the exercise step sensor 31 is converted by the exercise tempo phase shift circuit 39 (referred to as second correction) into the aforementioned ΔΦ. And is output as a tempo command signal Φm (t). That is, .PHI.m (t) =. PHI.h (t) +. DELTA..PHI. =. PHI.h (t) + AHB. [HBd (t) -HB (t)] (3) By correcting the phase in this way, the tempo can be controlled within a short time. Even if it fluctuates, it can be controlled so that it does not greatly change from the tempo Wh (t) of the exercise in terms of the average number of tempos in a relatively long time, so that the change in the amount of exercise becomes gentle and suitable for the elderly and the weak. Movement can be controlled.

Further, since the tempo of the tempo command signal to be commanded may fluctuate improperly quickly / slowly, this is constantly monitored, and if the tempo deviates from a preset upper / lower limit, the output tempo is slowed down. It is preferable to provide a tempo upper / lower limit setting circuit 61 for controlling in a fast direction. It goes without saying that the tempo upper / lower limit setting circuit 61 can be used in other embodiments. The environment sensor 4
Although the description of 1 is omitted, it may be used.

Embodiment 3 In the case of the first embodiment, the transmission of the tempo command signal to the user has been described by way of example by sound. However, walking and jogging are often performed with multiple friends, and when leaked sounds are heard by others, they disturb the pace and are not welcome. Also,
Some people find it difficult to exercise with earphones. Therefore, a vibration oscillator that is in close contact with the user's body or on clothes may be used instead of the sound generator (earphone) 43. The vibration oscillator is a vibration oscillation circuit (not shown).
1 inside the tempo output means 42 of FIG.
A vibrator is used in place of the earphone 43. The frequency of this vibration is several tens Hz or less, which is hard to be heard by the ear.

In addition, if the above-mentioned vibration is used for a long time, the user may feel that the freshness lacks freshness. Since such an inappropriate state of mood has a considerable effect on the results of exercise, for example, light is emitted by a light emitter (a lamp, a flashlight, a light emission of a screen of the display device 34, etc.) mounted on the surface of the main body case 100. A signal may be sent. The user can adjust the tempo if he / she feels that light is emitted without necessarily looking at the light emitting device. Further, for example, a picture of a runner or various animations may be graphically displayed on the screen of the display device 34, and the tempo may be transmitted by the movement of the picture.

Embodiment 4 Immediately after starting exercise,
The pulse rate is often far from the target pulse rate,
The reason is that the user's mental instability to start exercise is not a problem of control of the health promotion system (eg, palpitations increase before starting even though they are not exercising yet).
Often based on. Since the control based on the pulse rate of the user in such a state does not produce a good result, for example, in the case of the circuit of FIG. A data amount attenuator S1 is inserted on the output side of the exercise tempo increase / decrease amount conversion circuit 36C,
(S1 is a digital data value reduction) For a predetermined time immediately after the start of exercise, for example, for a few seconds to several minutes to wait for the palpitations to subside, the data amount attenuator S1 is set to the minimum level, and the first correction is performed. Correction signal KHB
[HBd (t) -HB (t)] may be cut off so that the first correction is not performed. After a predetermined time, by automatically and gradually returning the data amount attenuator S1, it is possible to return to the control state for performing the first correction described in the first embodiment without shock. That is, α is changed from zero to 1 with time.
Wm (t) = Wh (t) + α · KHB · [HBd (t) −HB (t)] (4)

The mechanism described above can be similarly used for the second correction 39 of the second embodiment. That is, in the case of the circuit of FIG. 5 according to the second embodiment, the data amount attenuator S1 is inserted as shown in FIG. Thereafter, the correction amount is gradually restored. If α is zero, the user's exercise tempo is output as it is, and such a state is referred to as user tempo copying control. Control for changing the correction amount with time by changing α with time is referred to as correction amount change control.

Embodiment 5 FIG. During warm-up immediately after the start of exercise and during cool-down toward the end of exercise, due to the difference in exercise experience of the user, it is difficult to exercise in accordance with the commanded tempo, or the tempo cannot be stabilized Some people. Thus, the difference between the pulse rate of the user and the target pulse rate is monitored until the pulse rate is almost stabilized at a high value immediately after the start of exercise and until the pulse rate is stabilized at a low value at the end of the exercise. It is also possible to control the tempo command signal based on only the difference (this control is called pulse rate control), and then switch to the control described in the first or second embodiment if stabilized. FIG. 8 shows a functional circuit diagram of a fifth embodiment configured to achieve such a function.

In FIG. 8, reference numeral 82 denotes a weighted average circuit;
37 is the output tempo Wm '(t-
This is a storage and addition circuit that stores 1) and adds the output of the difference calculation circuit 36b to this. The weighted averaging circuit 82 calculates the tempo Wh (t) of the exercise of the user and the target pulse rate HBd.
Signal for correcting the tempo command signal in a direction to make the difference between (t) and the current pulse rate HB (t) zero.
[HBd (t) −HB (t)] is added to the output value at time (t−1), and Wm ′ (t−1) + KHB [HBd
(T) −HB (t)]. That is,
If β is a weighting coefficient from 0 to 1 and W′m (t) is a tempo command signal to be output after weighting and adding, Wm ′ (t) = βWh (t) + (1−β) ｛Wm '(T-1) + KHB ・ [HBd (t) -HB (t)]｝ (4)

Here, β may be 1 during warm-up and cool-down, may be set to 0 during stable exercise, or may be gradually changed from 1 to 0 over time, thereby forcing at the start of exercise. A desired tempo is output as it is, and a system suitable for warm-up in which the tempo changes to a tempo for achieving the target pulse rate over time is obtained. Also, if β is initially set to 0 and gradually changed from 0 to 1 with time, the pulse rate of the user is led to a resting state with the passage of time from the output of the tempo for controlling the target pulse rate at first. A system suitable for a cool-down that ends exercise can be obtained. Control for performing weighting is referred to as weighting control, and control for changing β between zero and 1 with time is referred to as weight change control. The control based on only the pulse rate with β set to 1 is called pulse rate control.

Although it has been described that the weight coefficient β changes with time, the weight coefficient β may be arbitrarily set to a constant value. That is, on a day when the user is tired and desires to exercise at his own pace, β may be fixed to zero or any value close to zero. Furthermore, if β is switched between the above-mentioned value and a value between 0 and 1 at a selectable predetermined switching pace, so-called interval practice becomes possible.

Further, when the current pulse rate exceeds the target pulse rate during exercise and becomes abnormally high outside the predetermined range, it is assumed that an excessively severe load is applied to the body. Β is set to a value close to zero in order to match the output tempo with the user's pace, and when the current pulse rate becomes abnormally lower than the target pulse rate outside the predetermined range, Assuming that only a light load is applied, β may be set to a value close to 1 in order to match the output tempo with the tempo necessary to increase the pulse rate.

As described above, FIG. 8 is described with reference to FIG.
As an example, weighting control is introduced into the system of FIG. 5, but it is of course possible to introduce the system into the phase control system of FIG.

Embodiment 6 FIG. A pulse rate calculating circuit 32a and a tempo calculating circuit 31 of the control circuit of FIG.
In a, a delay substantially equivalent to the average time (for example, a primary delay of several seconds) occurs. Also, humans cannot change their exercise speed without a delay of a few seconds from the indicated tempo, so the pulse can vary from a few seconds to the change in the added exercise tempo depending on the individual or the health condition of the day. Various time delays of tens of seconds occur.

As described above, when the system according to each of the embodiments described above is viewed as a closed loop control system that makes a round, as shown in FIG. Since a plurality of elements (close to elements) exist in the loop, a hunting phenomenon occurs in which the tempo of the output tempo command signal fluctuates up and down at intervals of several tens of seconds unless the system is configured to have appropriate characteristics.

In such a state, the purpose of the health promotion system cannot be achieved at all.
It is necessary to insert a delay control element of several tens of seconds into the circuit constituting the circuit 8 to form a stable control loop as a whole. As a specific method, the case of FIG. 3 of the first embodiment will be described.
Calculation circuit 3 for calculating the difference between d (t) and current pulse rate HB (t)
By using 6b as an integral system, Wm (t) = Wh (t) + KHB1 · [HBd (t) −HB (t)] + KHB2 · Σ [HBd (t) −HB (t)] (5) I do. By adjusting the time constant of this integration, a system capable of minimizing the deviation can be configured extremely stably. In the description of each of the above embodiments, a circuit is synonymous with the means of the present invention.

Embodiment 7 FIG. FIG. 10 shows another use form of the health promotion system according to the present invention. FIG. 10 shows an example of exercise performed using a device in a room, and the figure is a so-called treadmill, in which a health promotion system is housed inside a control device of the device, and a user uses an earphone 43 and a sensor 3.
Exercise while wearing 1, 32. When using such a device, the exercise step sensor 31 can be attached to the side of the device.

[0054]

As described above, the health promotion system of the present invention corrects the current pulse rate based on the difference between the target pulse rate and the current pulse rate based on the user's current exercise tempo, Since the first correction means for outputting the tempo command signal is provided, the control delay of the tempo command signal is reduced, and the stability of the pulse rate is improved.

Further, there is provided second correction means for correcting the phase based on the difference between the target pulse rate and the current pulse rate with reference to the phase of the tempo of the current exercise of the user and outputting it as a tempo command signal. Therefore, there is no delay in controlling the load applied to the user, and the stability of the pulse rate is improved.

Further, since the tempo command signal is transmitted by vibration which cannot be heard as sound to the user's body, an effect of not disturbing surrounding people can be obtained.

Further, since the tempo command signal is transmitted to the user as a sound signal or an optical signal, the tempo command signal can be properly used according to the situation at the place of use.

Also, since music having the same tempo can be used as the sound signal as the tempo command signal, there is an effect of giving the user a favorable atmosphere.

The optical signal as the tempo command signal is
Since it is shown to the user as a graphic screen that changes according to the tempo, there is an effect of giving the user a favorable atmosphere.

In addition, since the user tempo copying control can be executed to match the tempo of the output tempo command signal with the exercise step of the user, the user who is not using the apparatus for the first time is effective and the health is improved.

Further, for a predetermined period of time, the pulse rate control for controlling the output tempo based only on the difference between the target pulse rate and the current pulse rate, and the pulse rate control tempo and the user's exercise tempo. Since the weight control for outputting the weighted average is provided, even a beginner who cannot exercise according to the commanded tempo can safely warm up and cool down.

After executing the user tempo copying control for adjusting the tempo of the output tempo command signal to the exercise step of the user, the tempo is gradually increased to a value corrected by the first or second correction means. Since the correction amount change control for changing can be executed, it is effective for the health promotion without imposing a burden on the user who uses for the first time.

Since the first correction means has a delay control circuit for a predetermined time, the pulse rate can be controlled stably.

Further, since the second correction means has a delay phase control circuit for a predetermined time, the pulse rate can be controlled stably.

Further, since the upper and lower limits of the output tempo can be set, the output tempo can be used with ease.

Further, since at least two of the user tempo copying control, the pulse rate control or the weighting control, and the correction amount change control can be selectively switched to be used, an appropriate control mode suitable for the user's preference is taken. Can be.
