Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for measuring kinetic consumption energy consumed by the movement of an object to be measured such as a human being.

[0002]

2. Description of the Related Art Conventionally, as a device for measuring the amount of exercise of a person in daily life, for example, a pedometer using the principle of a pendulum has been developed and sold by each company for health management. Also, a calorie consumption meter (hereinafter referred to as exercise energy consumption measuring device) has been developed using the principle of this pedometer.

[0003]

However, in this type of kinetic energy consumption measuring device, the number of steps is measured from the vibration of the pendulum that occurs with each step of a human walking, and Since the calorie consumption value was calculated only based on the measured number of steps, comparing the case of walking the same number of steps on a horizontal road and a slope, the value of the slope of the road is calculated when calculating the calorie consumption value. Therefore, the same value is designated as the step count value and the calorie consumption value, and they are displayed as if they have the same exercise amount. For this reason, there is a possibility that a person who manages health based on the calorie consumption value may have a problem that he / she performs wrong health care.

Particularly in recent years, the number of underground structures has increased in the living environment of human beings, while the number of underground structures has increased, and the depth of the underground structures has tended to increase. There is a risk that the exercise energy consumption measuring device based on a pedometer based on (flat land) may not provide sufficient health care. Therefore, an object of the present invention is to provide a measuring method in which the measurement accuracy of an exercise calorie meter is improved in consideration of the amount of vertical (up and down) displacement.

[0005]

According to the present invention, while I am investigating the difference in the characteristics of a condenser microphone, which is produced in large quantities at low cost in a microphone, especially an audio device, under various circumstances. This is an idea, and we have filed a number of applications for technology related to this. In such a situation, the invention of the present invention is a method for calculating the energy consumption of the object to be measured required for the movement based on the amount of vertical displacement and the amount of horizontal displacement accompanying the movement of the object to be measured, and It is in that device.

(Here, the vertical movement sensor detects any of vertical acceleration, vertical velocity, and vertical displacement, and is not limited to the vertical velocity sensor using the condenser microphone described in the following embodiment. Vertical acceleration sensor, vertical relative displacement sensor (for these,
I have already applied for it. In the case of the vertical acceleration sensor, if the output is integrated once, it becomes a velocity signal, and if it is integrated twice, it becomes a displacement amount signal. Needless to say, these sensors may be semiconductor elements, magnetostrictive elements, piezoelectric elements, crystal oscillators, or the like. )

[0007]

According to the above configuration, for example, the vertical movement sensor is attached to the waist, leg, etc. of the person to be measured, and is configured by a pressure receiving element (pressure sensor) including a condenser microphone by climbing up and down stairs. The vertical movement sensor causes vertical fluctuations that occur with its vertical displacement. (When the atmospheric pressure on the reference surface such as the ground surface is determined, the atmospheric pressure at each altitude based on it is reduced in inverse proportion to the altitude. Based on the difference in atmospheric pressure values in the vertical direction of the atmosphere, and the vertical displacement amount is calculated from the detected output. Exercise energy consumption (calorie consumption) is calculated based on the amount of directional displacement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a condenser microphone which constitutes an up-and-down speed sensor will be described with reference to FIG. 1, and then the device for utilizing the condenser microphone as a pressure receiving sensor and remodeling points will be described in detail. In FIG. 1, reference numeral 10 denotes a commercially available audio condenser microphone for audio, which is roughly divided into a cylindrical casing 11, a circuit board 12, an FET transistor 13, a spacing member 14, a pressure receiving electret film 15a,
They are the fixed electrode plate 15b, the lead wire 17 for external extraction, and the like.

Next, the above components will be described in detail. The cylindrical casing 11 has a small hole 1 through which the lead wire 17 penetrates through a bottom wall that constitutes a bottom end circular shape bottom portion.
1a is bored, and the opening formed at the upper end of the casing 11 is entirely covered with a mesh-like protective member 19. The circuit board 12 is arranged at the bottom of the casing 11, on which the FET transistor 13 is mounted, and the lead wire 17 is connected. Further, in the same figure, in the peripheral portion between the pressure-receiving electret film 15a and the fixed electrode plate 15b, a ring-shaped insulating film 16 for spacers is provided in order to maintain a constant distance and to ensure insulation. Is installed.

Further, the pressure receiving electret film 15a, the spacer insulating film 16 and the fixed electrode plate 15b greatly restrict the flow of air inside and outside the casing 11 through the upper end opening.
That is, the air flow resistance value through the pressure-receiving electret film 15a, the spacer insulating film 16 and the fixed electrode plate 15b is set to a large value,
As a result, the frequency characteristic for audio is secured. It should be noted that the fixed electrode plate 15b is provided with fine holes (not shown) for air circulation, and the circuit board 12 is provided in close contact with the bottom wall of the casing 11, and the small holes 11a are provided.
The flow of air through the is greatly regulated.

The above is the main configuration of the condenser microphone which is generally marketed and used for audio. Here, the commercially available condenser microphone 10 is modified as a pressure receiving sensor and used as a vertical velocity sensor (vertical movement sensor), so that the following innovations and modifications are made. That is, reference numeral 18 denotes a cylindrical sealing auxiliary member having rigidity, both ends of which are opened, and the inner diameter thereof is slightly larger than the outer diameter of the condenser microphone 10. Further, the lower end portion of the sealing cylindrical auxiliary member 18 protrudes outward from the bottom wall of the condenser microphone 10 and does not flow out when the resin sealant 20 is poured for sealing. It has the function of a wall.

As described above, the condenser microphone 1
The cylinder of the condenser microphone 10 by sealing the small hole 11a of the bottom wall of 0 from the outside, that is, by covering the air pressure in the condenser microphone 10 through the small hole 11a so as not to be affected by the atmospheric pressure. It completely blocks the flow of air through the bottom wall of the cylindrical casing 11, that is, the air outside the sealing tubular auxiliary member 18 from entering the inside. Therefore, the cylindrical casing 11
The flow of air inside and outside the electret film for pressure reception 1
5a, fixed electrode plate 15b, spacer insulating film 1
Air is circulated through the gaps of the contact portions formed between 6 and the like, that is, the minute gaps formed on the respective contact surfaces and the like.

Next, the operation of the condenser microphone 21 configured as described above will be described. Modified condenser microphone 2 described in the above description of the configuration
1. That is, when the condenser microphone 21 that is in a highly airtight state in which the cylindrical casing 11 is substantially sealed from the outside air is lifted in the vertical direction in the atmosphere, the ambient atmospheric pressure is reduced accordingly (this) Is due to the decrease in atmospheric pressure from the ground surface upwards). At this time, the pressure-receiving electret film 15 as described above
a, fixed electrode plate 15b, spacer insulating film 16
A very large flow resistance generated in a minute gap formed in a peripheral contact portion such as a time delays outflow of air in the cylindrical casing 11, and a change in external pressure causes a change in external pressure. A temporary difference is created in each pressure. As a result, the modified condenser microphone 21 outputs a voltage signal e (t) proportional to the ascending / descending speed (vertical speed) of the object to be measured.

Next, this will be explained theoretically. The output voltage from the modified condenser microphone 21 shown in FIG. 2 is e (t), the height is h, the pressure change / voltage conversion gain is k, and the volume of the space formed in the cylindrical casing 11 is v. , The pressure-receiving electret film 15a,
The flow resistance of the gap formed between the fixed electrode plate 15b, the spacer insulating film 16 and the like and the cylindrical casing 11 is r, and the pressure receiving electret film 1 is
Capacitance between 5a and fixed electrode plate 15b is C, built-in F
Assuming that the input impedance of the ET transistor 13 is R, the air density in the cylindrical casing 11 is ρ, the gravitational acceleration is g, and the complex angular frequency is s, the vertical movement speed and a modified condenser microphone 21 for detecting it. The relation with the output voltage of is given by the following equation.

[0015]

[Equation 1]

If the physical characteristics of the modified condenser microphone 21 are set so as to satisfy the conditions shown in the following equations 2 and 3, then the equation 4 holds. I.e.

[0017]

[Equation 2]

[0018]

[Equation 3]

[0019]

[Equation 4]

That is, the above equation 4 is obtained by modifying the commercially available condenser microphone 10 as shown in FIG. 1, and the magnitude of the output signal e (t) output therefrom is proportional to the speed of vertical movement. And changes to form a vertical speed sensor.

Here, the basic principle of the present invention will be described.
That is to say, everyday people walk on flat roads, slopes, stairs, etc., but on flat roads, energy is not so much consumed, but on walking uphill, stairs, etc. You have to lift yourself up by yourself using as much energy as you need. Also, when walking downhill, you have to step by step so that you do not gain momentum, so you will consume more energy than you think.

That is, based on such an idea, description will be made with reference to FIG. However, it is considered that the stride of a human walking is fixed to some extent and a predetermined value can be set. That is, in FIG. 6, point B, point C, point D, and point E (A
It is assumed that the altitude at point D is the same as the altitude at point D, the altitude at point E is low, the altitudes at points B and C are high, and the altitude at point B is the highest. ) Is taken as a step (that is, when this is considered as a vector, the magnitudes of the vectors AB, AC, AD, and AE are equal (by considering that the stride is the same), and the direction (gradient Thing) is different). Here, point B, C
The height (displacement in the vertical direction) from point A to point D, point E, and point E is measured, and vectors AB, AC, A
Considering that the size of D and AE is set as the same value as the stride, the size of the horizontal component (see the sizes of the vectors ABH, ACH, ADH, and AEH in FIG. 6) is determined by the Pythagorean theorem. It is calculated.

That is, the vertical component of each step (see the magnitudes of the vectors ABv, ACv, AEv in FIG. 6).
And horizontal components (vectors ABH, ACH, A in FIG. 6)
DH, AEH (see size) is multiplied by a coefficient (set based on experimental data) to calculate the energy consumption for vertical and horizontal displacement, and add them together. Then, the exercise energy consumed for one step moving from the point A to the point B, the point C, the point D or the point E is calculated.
