Description

  The present invention is a wet bulb black that calculates the wet bulb black bulb temperature W based on the temperature T measured by the temperature sensor, the relative humidity Th measured by the relative humidity sensor, and the black bulb temperature Tg measured by the black bulb temperature sensor. The present invention relates to a black ball heat stroke meter and a terminal device provided with a sphere temperature calculation means.

There is a risk of heatstroke if you perform physical activity such as sports or work in a hot and humid environment.
Therefore, in order to avoid suffering from heat stroke, an approximate value of WBGT is adopted as a heat index which is a guide for grasping the thermal environment around the active person, and in accordance with the stage of the approximate value of WBGT in advance. Measured temperature and humidity around the activist, calculated the WBGT approximate value in the activator's activity environment based on the measurement results, and calculated WBGT There is known a heat index measuring device for notifying a user who is an active person of a heat stroke countermeasure corresponding to an approximate value (see, for example, Patent Document 1).

  More specifically, in the thermal index measuring device of Patent Document 1, five stages of danger levels 1 to 5 are set in advance according to the approximate value of WBGT, and each danger level is in accordance with the amount of exercise of the user. It is divided into three levels of risk, and for each risk level, a countermeasure against heat stroke is set according to the risk level and the risk level, and the calculated WBGT approximate value and the user's exercise amount are set. The measures against heat stroke are displayed to the user, and if necessary, a warning that the continuation of the activity is dangerous is given.

Next, a schematic configuration of the black ball heat stroke meter 1 will be described.
As shown in FIG. 2, the black bulb heat stroke meter 1 includes a temperature sensor 11 that measures the temperature T (° C.), a relative humidity sensor 12 that measures the relative humidity Th (%), as shown in FIG. A black sphere temperature sensor 13 for measuring the black sphere temperature Tg (° C.) inside the black sphere 2 and a semiconductor acceleration sensor 14 for measuring acceleration caused by the physical movement of the user are provided.

As described above, the measurement calculation unit 3 is provided with the setting switch 25 in order to perform physical settings of the user.
This setting switch 25 is for setting the age and physical strength of the user.
As such a setting switch 25, it is preferable to employ a change-over switch or the like that can perform a multi-stage change.
For example, as a user, five models of infants, elementary school students, junior high school students, weak physical strength adults and strong physical strength adults before entering elementary school are prepared in advance, and one of these models can be selected. As the setting switch 25, a change-over switch that can be switched in five steps can be employed.

In addition, the measurement calculation unit 3 performs various calculations and displays using a built-in microcomputer.
In addition to the above, the measurement calculation unit 3 includes a wet bulb black bulb temperature calculating means 31 for calculating the wet bulb black bulb temperature W, and an exercise amount automatic for obtaining the user's exercise amount X as shown in FIG. An obtaining means 32, a corrected wet bulb black bulb temperature calculating means 33 for correcting the wet bulb black bulb temperature W described above, and a risk determining means 34 for judging the risk from the correction result of the corrected wet bulb black bulb temperature calculating means 33. In addition, a determination result notifying means 35 for notifying the determination result determined by the risk determining means 34 and a liquid crystal display panel control device 36 for controlling the liquid crystal display panel 21 are provided.

The wet bulb black bulb temperature calculation means 31 is based on the temperature T measured by the temperature sensor 11, the relative humidity Th measured by the relative humidity sensor 12, and the black bulb temperature Tg measured by the black bulb temperature sensor 13. It is a calculation means for calculating the sphere temperature W.
As an example of the wet bulb black bulb temperature calculation means 31, a device that calculates the wet bulb black bulb temperature W by sequentially performing a plurality of types of calculations shown below can be employed.
That is, from the temperature T first measured by the temperature sensor 11,
Saturated water vapor pressure E = 6.11 * 10 ^ {7.5 * T (T + 237.3)}
To obtain a saturated water vapor pressure E. Note that “*” in the above expression indicates multiplication, and “^” indicates power. The same shall apply hereinafter.

Next, from the obtained saturated water vapor pressure E and the relative humidity Th measured by the relative humidity sensor 12,
Water vapor pressure Es = E * Th / 100
To calculate the water vapor pressure Es.
Subsequently, from the obtained water vapor pressure Es and the temperature T measured by the temperature sensor 11,
Wet bulb temperature Tb = 0.23 * T + 0.504 * Es + 3.45
Is calculated to obtain the wet bulb temperature Tb.

Then, from the obtained wet bulb temperature Tb and the black bulb temperature Tg measured by the black bulb temperature sensor 13,
Wet bulb temperature W = 0.7 * Tb + 0.3 * Tg
To calculate the wet bulb black bulb temperature W.
Such wet bulb black bulb temperature calculating means 31 is adapted to send the obtained wet bulb black bulb temperature W to the corrected wet bulb black bulb temperature calculating means 33.

The exercise amount automatic acquisition means 32 performs a predetermined calculation based on the acceleration measured by the semiconductor acceleration sensor 14 and the setting of the user's age and physical strength selected by the setting switch 25 to thereby obtain the user's exercise amount X (Kcal / h) is obtained automatically.
As a specific example, the momentum automatic acquisition means 32 stores conversion coefficients set for each of the five models that can be selected by the setting switch 25, and at the most recent predetermined time. An average acceleration that is an average value of acceleration (for example, the average acceleration for the last 5 minutes) is calculated as needed, and the product of the calculated average acceleration and the conversion coefficient of the model selected by the setting switch 25 is used as the momentum X (Kcal / H) can be automatically acquired.
Here, the automatic momentum acquisition means 32 has a function of excluding large acceleration exceeding human motor ability and acceleration due to minute vibrations with a short cycle, and thus the user is on the vehicle. Acceleration sometimes received can be excluded.
Such a momentum automatic acquisition means 32 sends the calculated momentum X to the corrected wet bulb temperature calculation means 33.

The correction wet bulb black bulb temperature calculation means 33 corrects the wet bulb black bulb temperature W obtained by the calculation of the wet bulb black bulb temperature calculation means 31 based on the momentum X acquired by the momentum automatic acquisition means 32. is there.
That is, the corrected wet bulb black bulb temperature calculating means 33 is based on the wet bulb black bulb temperature W calculated by the wet bulb black bulb temperature calculating means 31 and the momentum X acquired by the momentum automatic acquiring means 32.
Corrected wet bulb temperature Wb = W + 0.55 * {e ^ (0.005 * X)} * a
(Where e is the base of the natural logarithm, a is a coefficient satisfying 0.5 ≦ a ≦ 1.5)
Is calculated to obtain the corrected wet bulb black bulb temperature Wb (° C.).
Such a corrected wet bulb black bulb temperature calculating means 33 is adapted to send the obtained corrected wet bulb black bulb temperature Wb to the risk determining means 34 and the liquid crystal display panel control device 36.

Here, the corrected wet bulb black bulb temperature calculating means 33 stores five types of coefficients a set corresponding to each of the five models that can be selected by the setting switch 25, and from the setting switch 25. It is preferable to employ calculation means that uses the coefficient a set corresponding to the model selected by the setting switch 25 for calculation.
If such a corrected wet bulb black bulb temperature calculating means 33 is adopted, a coefficient a corresponding to each of an infant, an elementary school student, a junior high school student, an adult with weak physical fitness, and an adult with strong physical strength is automatically selected. For example, when the user is an infant, the coefficient a having a value close to 1.5 is automatically adopted, and when the user has strong physical strength, the coefficient a having a value close to 0.5 is automatically adopted. Then, the person a suitable for the user is automatically adopted.

  Here, a habituation mode changeover switch 27 is connected to the corrected wet bulb black bulb temperature calculation means 33. In the following description, a case where a push button type switch is adopted as the habituation mode changeover switch 27 will be described. However, the habituation mode changeover switch 27 is not limited to a push button type switch, and may be a tumbler switch, for example. Other structure switches can be employed.

The corrected wet bulb black bulb temperature calculating means 33 is in accordance with the operation of the habituation mode changeover switch 27, in the unaccustomed mode corresponding to the state where the user is not yet accustomed to exercise / work or heat, and Alternatively, a transition is made from one of the habituation modes corresponding to the state accustomed to heat to the other.
For example, the corrected wet bulb black bulb temperature calculating means 33 is set to the unaccustomed mode as the default initial mode when the power is turned on, and when the acclimatized mode changeover switch 27 is first pressed, After that, every time the acclimatization mode changeover switch 27 is pressed, the mode is shifted from one of the acclimatization mode and the unacclimation mode to the other.

The corrected wet bulb black bulb temperature calculating means 33 uses the coefficient a set corresponding to the model selected by the setting switch 25 as it is when operating in the unacclimated mode. .
On the other hand, when the correction wet bulb black bulb temperature calculating means 33 is operating in the habituation mode, the coefficient a set corresponding to the model selected by the setting switch 25 is multiplied by a correction coefficient smaller than 1. In other words, a value smaller than the coefficient a in the unacclimated mode is used as the coefficient a in the acclimatized mode.

The risk determination means 34 is a corrected wet bulb black bulb temperature obtained by the corrected wet bulb black bulb temperature calculating means 33 to determine which danger level corresponds to a heat stroke risk level set in a plurality of stages in advance. The determination is based on Wb.
Here, as the danger level of heat stroke, four stages of danger levels are set. That is, as the danger level of heat stroke, the “wet” level where the corrected wet bulb black bulb temperature Wb is 21 ° C. or higher and lower than 25 ° C., the “warning” level where the corrected wet bulb black bulb temperature Wb is 25 ° C. or higher and lower than 28 ° C. Four stages are adopted: a “strict warning” level where the corrected wet bulb black bulb temperature Wb is 28 ° C. or higher and less than 31 ° C., and a “danger” level where the corrected wet bulb black bulb temperature Wb is 31 ° C. or higher.
Such a risk determination means 34 is configured to send a risk level as a determination result to the determination result notifying means 35 every time a predetermined time elapses.

The determination result notifying means 35 notifies the user of the danger level that is the determination result determined by the risk determining means 34.
That is, the determination result notification unit 35 is connected to the five LEDs 22A to 22E and the speaker 23 described above.
Then, when the determination result notification unit 35 receives the risk level as the determination result from the risk determination unit 34, the determination result notification unit 35 selects the LED corresponding to the determined determination result from the five LEDs 22A to 22E, and selects the selected LED. The light is turned on and a sound corresponding to the danger level is output from the speaker 23.

Specifically, when the received determination result is at the “attention” level, the determination result notifying means 35 turns on the green LED 22B and each time the determination result is received, in other words, every time a predetermined time elapses. The loud sound corresponding to the “caution” level and a short notification sound are output from the speaker 23.
If the determination result is the “alarm” level, the determination result notifying means 35 turns on the yellow LED 22C, and the alarm sound with a relatively large volume corresponding to the “alarm” level is displayed with the determination result equal to or lower than the “caution” level. It continues to output from the speaker 23 until it returns.

If the judgment result is at the “severe alarm” level, the judgment result notifying means 35 turns on the pink LED 22D and makes a relatively noisy alarm sound corresponding to the “severe alarm” level. It continues to output from the speaker 23 until it returns.
If the determination result is at the “danger” level, the determination result notifying means 35 turns on the red LED 22D and continues a noisy alarm sound corresponding to the “danger” level until the determination result returns to the “serious alarm” level or lower. And output from the speaker 23.

The liquid crystal display panel control device 36 causes the liquid crystal display panel 21 to display the corrected wet bulb black bulb temperature Wb obtained by the corrected wet bulb black bulb temperature calculating means 33.
That is, the liquid crystal display panel 21 is connected to the liquid crystal display panel control device 36.
When the liquid crystal display panel control device 36 receives the corrected wet bulb black bulb temperature Wb from the corrected wet bulb black bulb temperature calculation means 33, the liquid crystal display panel control device 36 displays the value of the corrected wet bulb black bulb temperature Wb on the liquid crystal display panel 21. It is formed (see FIG. 1).

According to this embodiment as described above, the following effects can be obtained.
That is, the wet bulb that calculates the wet bulb black bulb temperature W based on the temperature T measured by the temperature sensor 11, the relative humidity Th measured by the relative humidity sensor 12, and the black bulb temperature Tg measured by the black bulb temperature sensor 13. Since the black bulb temperature calculation means 31 is provided, the wet bulb black bulb temperature W in consideration of the influence of the radiant heat is calculated, and the danger level in consideration of the influence of the radiation can be grasped.
In addition, a predetermined calculation is performed from the wet bulb black bulb temperature W calculated by the wet bulb black bulb temperature calculating unit 31 and the momentum X acquired by the automatic momentum acquisition unit 32 to obtain a corrected wet bulb black bulb temperature Wb. The ball black bulb temperature calculating means 33 is provided, and the wet bulb black bulb temperature calculating means 33 corrects the wet bulb black bulb temperature W according to the momentum X. In other words, the influence of the momentum X is corrected to the wet bulb. Since it is reflected in the black sphere temperature Wb, it is not necessary to change the reference value for determining whether or not the calculated value obtained as a result of the calculation indicates a dangerous state depending on the momentum X. Thus, the reference value becomes a fixed value, and the user's risk level can be intuitively grasped with one calculated value of the corrected wet bulb black bulb temperature Wb.

Further, the black bulb temperature sensor 13 can capture a hot environment including radiant heat, and can accurately capture a hot environment corresponding to radiant heat that varies depending on the situation of the place where the user is active.
For this reason, even if the radiant heat is different between the case of activity indoors or the case of activity outdoors, even if the radiant heat differs depending on the type of ground surface (such as soil, concrete and asphalt), Even if the radiant heat is different between the distance from the ground surface, specifically when it is active on the ground surface and when it is active on the rooftop of the building, the black sphere temperature sensor 13 reflects the influence of the radiant heat received by the user It is possible to accurately capture the local heat environment according to the user's activity location.
And because it can accurately capture the hot environment according to the distance from the ground surface, an infant in a stroller, a small short child, or even the whole body that could not be captured with conventional instruments However, pets such as dogs and cats that are close to the surface of the earth can accurately capture the hot environment, and can also prevent heatstroke in an extremely localized hot environment.

  In addition, the corrected wet bulb black bulb temperature calculation means 33 has an unaccustomed mode corresponding to a state in which the user is not yet accustomed to exercise / work or heat, and a state in which the user is accustomed to exercise / work or heat. A corresponding habituation mode is provided, and when the habituation mode changeover switch 27 is pressed, the mode shifts from one of the habituation mode and the unhabituation mode to the other, so that the user is accustomed to exercise / work or heat, When the resistance to the hot environment is improved, it is possible to notify the user of the risk corresponding to the improved resistance to the hot environment, and accordingly, it is possible to perform the appropriate risk notification according to the situation of the user. .

(Second Embodiment)

In the second embodiment, the momentum automatic acquisition means 32 that automatically acquires the momentum X of the user in the first embodiment is manually acquired. The momentum manual acquisition in which the user acquires the momentum X by manually setting the momentum X. This is replaced by means 32A.
In the following description, the members and parts already described are denoted by the same reference numerals, and the description thereof is omitted or simplified.

The push button switch 26A for mode switching and the push button switch 26B for setting operation are connected to the momentum manual acquisition means 32A as shown in FIG.

Here, the user's activities are classified in advance into three stages of activities of light load activity, medium load activity and heavy load activity.
In the momentum manual acquisition means 32A, the range of the momentum X set for each of the light load activity, medium load activity and heavy load activity is stored.

In the above, the light load activity is an activity that does not place much load on the user's body, such as office work, housework, and driving of the vehicle, specifically, an activity in which the exercise amount X is in the range of 1 Kcal or more and less than 250 Kcal.
The medium load activity is an activity that places a certain amount of load on the user's body, such as walking, golf, and driving a bicycle, specifically, an activity in which the amount of exercise X is in a range of 250 Kcal or more and less than 490 Kcal.
The heavy load activity is an activity that places a considerable load on the user's body, such as jogging or soccer, specifically, an activity in which the amount of exercise X is in the range of 490 Kcal or more.

Then, the momentum manual acquisition means 32A shifts from the measurement mode to the momentum setting mode when the pushbutton switch 26A for mode switching is operated when the user manually sets the momentum X, and this pushbutton switch One of the three stages of activity is selected by the operation of 26A.
The momentum manual acquisition means 32A can be selected by operating the pushbutton switch 26A for mode switching when the pushbutton switch 26B for setting operation is operated while any of the three steps of activities is selected. Within the range of the amount of exercise X set for each of the activities, the amount of exercise X corresponding to the operation of the push button switch 26B for setting operation is set.

Here, as the momentum manual acquisition means 32A, for example, one that performs the following operation can be adopted in accordance with the pressing operation of the pushbutton switch 26A for mode switching. It is not limited.
The momentum manual acquisition means 32A selects the light load activity when the push button switch 26A for mode switching is pressed once.
Then, the momentum manual acquisition means 32A, when selecting the light load activity, issues a light load command to the liquid crystal display panel controller 36, and is one less than the minimum value in the range of the momentum X set for the light load activity. A numerical value (0 Kcal) is displayed on the liquid crystal display panel 21 on the screen.

The momentum manual acquisition means 32A selects the medium load activity when the pressing operation of the pushbutton switch 26A for mode switching is continuously performed twice.
Then, the momentum manual acquisition means 32A, when selecting the medium load activity, issues a medium load command to the liquid crystal display panel control device 36, and is one less than the minimum value in the range of the momentum X set for the medium load activity. A numerical value (249 Kcal) is displayed on the screen of the liquid crystal display panel 21.

The momentum manual acquisition means 32A selects the heavy load activity when the pressing operation of the pushbutton switch 26A for mode switching is continuously performed three times.
When the heavy load activity is selected, the momentum manual acquisition means 32A issues a heavy load command to the liquid crystal display panel controller 36, and is one less than the minimum value in the range of the momentum X set for the heavy load activity. A numerical value (489 Kcal) is displayed on the screen of the liquid crystal display panel 21.

  The momentum manual acquisition means 32A is used by the user for setting operation while observing the value of the momentum X shown on the liquid crystal display panel 21 in a state where any of light load activity, medium load activity and heavy load activity is selected. When the push button switch 26B is pressed, the momentum X is set according to the pressing operation of the push button switch 26B for setting operation by the user.

That is, the momentum manual acquisition means 32A is formed to increase the value shown on the liquid crystal display panel 21 one by one when the push button switch 26B for setting operation is pressed once each time. The push button switch 26B is formed to continuously increase the value indicated on the liquid crystal display panel 21 by long pressing.
Then, the momentum manual acquisition means 32A adopts the settled value as the momentum X when the value of the momentum X shown on the liquid crystal display panel 21 settles because the user has completed the operation of the push button switch 26B for setting operation. Then, the adopted momentum X is sent to the corrected wet bulb black bulb temperature calculating means 33.

The momentum manual acquisition means 32A returns to the original measurement mode from the momentum setting mode when the pushbutton switch 26A for mode switching is operated after sending the adopted momentum X to the correction wet bulb black bulb temperature calculation means 33.
