Description

The present invention relates to sensor-equipped clothing, a physical condition management system, and a physical condition management program, and more particularly to a technique for monitoring a thermal load on the human body.

With the progress of global warming, it is important to take measures against heat to prevent the onset of heat stroke under heat. In order to prevent heat stroke, the heat index (Wet Bull Globe Temperature: WBGT) is used as one of the indexes for measuring and evaluating the hot environment. The heat index (WBGT) is an index focusing on the exchange of heat between the human body and the outside air, and has three factors: humidity, which has a large effect on the heat balance of the human body, the thermal environment around the person such as solar radiation and radiation, and air temperature. Incorporating elements.

Specifically, the black bulb temperature, the wet bulb temperature, and the dry bulb temperature are measured, and the heat index is obtained by the following equation (1) based on these measured values (see Non-Patent Document 1).
Heat index (WBGT) [° C] = 0.7 x wet-bulb temperature +0.2 x black globe temperature +0.1 x dry-bulb temperature
... (1)

For example, it is known that when the heat index [° C] obtained by the above formula (1) exceeds 28 [° C], the number of heat stroke patients increases remarkably, which is an effective index for heat measures. .. In this way, as one of the measures against heat, the heat index at that point is measured using a WBGT meter, and when the heat index (WBGT) is relatively high, actions such as avoiding going out or strenuous work are taken. The method used as a guideline for is widely used.

Conventional WBGT meters that calculate this heat index include, for example, a black bulb temperature sensor, a temperature sensor, and a humidity sensor, and the black bulb temperature, wet bulb temperature, and dryness for calculating the heat index (WBGT). Measure the ball temperature respectively. A conventional WBGT meter is generally composed of a relatively large device, and it is difficult to place it at an arbitrary place. For example, the Heat Index (WBGT) published by the Ministry of the Environment is a value that represents a wide area. Thus, it is not easy to grasp the local heat index (WBGT).

However, in reality, the heat balance of each user is greatly affected by the local environment. For example, the environment varies greatly depending on where each user is, such as outdoors and indoors, sun and shade, lawn and concrete. Moreover, even in the same place, the influence of radiation from the ground, for example, differs greatly between a tall adult and a short child. Further, the temperature and humidity inside the clothes greatly change depending on the clothes worn by the user, the exercise state of the user, and the sweating state, which affects the heat balance of each user.

A heat index calculation unit that calculates the heat index of the user wearing the sensor-equipped garment based on the radiant heat and the user's heat index calculated by the heat index calculation unit are presented. It is characterized by having a presentation unit.

In order to solve the above-mentioned problems, in the physical condition management program according to the present invention, the physical condition management system uses a computer to obtain the temperature measured by the temperature sensor, the humidity measured by the humidity sensor, and the humidity.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 1 to 9.
[First Embodiment]
The sensor-equipped clothing 1 according to the present embodiment includes clothing 2 worn by the user and a sensor device 1A attached to the clothing body 20, and measures the environment inside the clothing and the radiant heat received by the user due to sunlight.

As shown in FIGS. 1 and 2, the sensor device 1A is attached to the surface of the clothes 2 worn by the user in contact with the outside air, that is, the outside of the clothes body 20. Further, in the present embodiment, the sensor device 1A is attached to the outside of the garment body 20 corresponding to the back side of the user.

The garment 2 includes, for example, as shown in FIG. 1, a garment body 20 having a front body and a back body, a sleeve, and a shirt having a collar. In addition to shirts, clothing 2 includes clothing such as vests, compression shirts, jerseys, tank tops, and outerwear. Further, the garment body 20 in contact with the user's body may be made of a stretchable cloth so as to be appropriately in close contact with the user's body.

The outer surfaces of the garment 2 and the garment body 20 are surfaces in contact with the outside air, and are hereinafter referred to as "surface 2a". Further, the inside of the garment 2 and the garment body 20 is a surface on the skin B side of the user who wears the garment 2, and is hereinafter referred to as "back surface 2b".

The garment body 20 includes an opening 2h formed at an arbitrary position. Further, on the surface 2a of the garment body 20, for example, a socket and a stud (female member) of the snap button 15 are provided at positions around the opening 2h. The stud (male member) of the snap button 15 is provided on the outer surface of the first wall member 10a of the housing 10 described later, which is included in the sensor device 1A. The sensor device 1A is detachably attached to the clothes 2 by a snap button 15.

By making the clothes 2 and the sensor device 1A removable, after the sensor-equipped clothes 1 are used by the user, the sensor device 1A can be detached from the clothes 2 and only the clothes 2 can be washed. Further, it is possible to prevent a failure of the sensor device 1A due to getting wet.

Further, the sensor device 1A is attached to the garment body 20 so as to be arranged, for example, from the center of the back of the user to the height of the scapula. When the sensor device 1A is attached to such a position, an appropriate space S is formed between the surface of the user's skin B and the temperature / humidity sensor 11 described later, which is suitable for measuring the temperature / humidity environment in clothes. In addition, the back is a part of the body where the amount of sweating is relatively large, and it is also suitable for measuring the humidity in clothes that sufficiently reflects the influence of sweating by the user.

[Sensor device configuration]
The sensor device 1A is supported by a housing 10, a temperature / humidity sensor 11 including a temperature sensor 11a and a humidity sensor 11b supported by a first wall member 10a of the housing 10, and a second wall member 10b of the housing 10. The radiant heat sensor 12 is provided. The sensor device 1A is attached so that the first wall member 10a of the housing 10 faces the outside of the clothing body 20.

Further, the control board 14 is housed inside the housing 10. A battery (not shown) is housed inside the housing 10 to supply electric power to the control board 14.

The housing 10 is a container formed in a substantially rectangular parallelepiped including the first wall member 10a and the second wall member 10b. The first wall member 10a and the second wall member 10b are provided so as to face each other. For example, the housing 10 has a bottom surface (outer surface of the first wall member 10a) and an upper surface (outer surface of the second wall member 10b) having a rounded quadrangle in a plan view.

The housing 10 can be formed of, for example, a polymer material such as ABS resin, rubber, or silicone resin. The size of the housing 10 is formed to be a size that can be attached to the user's clothing, for example, about 5 cm × 3 cm × 1 cm.

The housing 10 supports the temperature / humidity sensor 11 with the first wall member 10a, and supports the radiant heat sensor 12 with the second wall member 10b facing the first wall member 10a. The first wall member 10a and the second wall member 10b of the housing 10 are each provided with one hole. The temperature / humidity sensor 11 fits into the hole formed in the first wall member 10a. Further, the radiant heat sensor 12 is fitted into the hole formed in the second wall member 10b.

As described above, the temperature / humidity sensor 11 is provided in a part of the first wall member 10a, and the radiant heat sensor 12 is provided in a part of the second wall member 10b. The radiant heat sensor 12 is provided so as to be exposed to the outside through the hole of the second wall member 10b. Further, the temperature / humidity sensor 11 may be provided so as to be exposed to the outside through the hole of the first wall member 10a.

In the present embodiment, the outer surface of the second wall member 10b is the surface on the side in contact with the outside air, and the outer surface of the first wall member 10a is the clothes 2 worn by the user, the back surface 2b of the clothes 2, and the skin of the user. It is a surface in contact with the space S in the clothes formed between the surface of B and the surface of B.

Further, a part of the outer surface of the first wall member 10a where the temperature / humidity sensor 11 is provided is exposed from the opening 2h of the clothes 2 to the space S inside the clothes 2. For example, snap buttons 15 are provided on the surface 2a of the garment 2 and the outer surface of the first wall member 10a so that the region of the first wall member 10a where the temperature / humidity sensor 11 is provided coincides with the opening 2h.

Further, for example, the outer periphery of the hole formed in the first wall member 10a projects further outward from the outer surface, and is formed at a height that matches the height of the snap button 15. As a result, the temperature / humidity sensor 11 supported by the first wall member 10a can come into more direct contact with the space S in the clothes from the opening 2h formed in the clothes 2. The temperature / humidity sensor 11 may be configured to be in contact with the space S in the clothes through, for example, a thin film of a polymer material.

As the temperature / humidity sensor 11, for example, a sensor in which a capacitance type humidity sensor 11b and a temperature sensor 11a such as a semiconductor temperature sensor are integrally provided on one IC chip is used. Alternatively, for example, a thermistor or the like can be used as the temperature sensor 11a. The temperature and humidity in the space S inside the clothes measured by the temperature / humidity sensor 11 are converted into signals indicating the temperature inside the clothes and the humidity inside the clothes by the processor 402 included in the control board 14 described later.

The radiant heat sensor 12 includes a black portion having a black surface and a thermistor 13 as a temperature sensor. The black portion can have any shape such as a flat plate or a curved plate. The thermistor 13 is arranged in contact with the back surface of the black portion of the radiant heat sensor 12.

As shown in FIGS. 1 and 2, at least the surface of the radiant heat sensor 12 exposed to the outside from the second wall member 10b of the housing 10 is black. The surface of the radiant heat sensor 12 can be blackened with, for example, iron oxide so as to absorb radiant heat (heat radiation) from sunlight or the like as much as possible. For example, it forms a matte blackened surface. As shown in FIG. 1, the radiant heat sensor 12 is formed in a disk shape, for example, and fits into a hole provided in the second wall member 10b of the housing 10.

As shown in FIG. 2, the thermistor 13 is provided on the back surface of the radiant heat sensor 12. The thermistor 13 is used as a temperature sensor that detects the temperature of the black portion. The resistance value detected by the thermistor 13 is converted into a signal indicating the temperature of the black portion and output by the processor 402 mounted on the control board 14.

As described above, when the electromagnetic wave emitted from the sun or the like reaches the surface of the black portion of the radiant heat sensor 12, it is converted into internal energy and the temperature of the black portion changes. The temperature of the black part rises according to the sunlight and radiation received and absorbed by the black part. The thermistor 13 can measure the radiant heat from the outside of the clothes 2 by measuring the temperature of the black portion.

As shown in FIG. 3, the control board 14 includes, for example, a computer including a processor 402 such as a CPU connected via a bus 401, a memory 403, a communication interface 404, and an input / output I / O 405, and their hardware resources. It can be realized by a program that controls. Further, the control board 14 includes an amplifier circuit (not shown), an A / D converter, and the like.

A program for the processor 402 to perform various controls and operations is stored in the memory 403 in advance. The memory 403 has an area for recording calibration data of the temperature / humidity sensor 11 and the radiant heat sensor 12.

The communication interface 404 is a communication control circuit for communicating with various external electronic devices via the communication network NW. The temperature inside the clothes, the humidity inside the clothes, and the radiant heat from the outside converted by the processor 402 are transmitted from the communication interface 404 to the physical condition management device 3 described later via the communication network NW.

As the communication interface 404, for example, a communication interface and an antenna corresponding to wireless data communication standards such as LTE, 3G, 5G, wireless LAN, and Bluetooth (registered trademark) are used.

The input / output I / O 405 is composed of an I / O terminal that inputs a signal from an external device and outputs a signal to the external device.

More specifically, the acquisition unit 30 collects temperature, humidity, and radiant heat measurement data from the sensor-equipped clothing 1 via the communication network NW, for example, at regular time cycles. The acquired sensor data is stored in the storage unit 34.

The heat index calculation unit 31 calculates the heat index of the user who wears the sensor-equipped clothes 1 based on the temperature and humidity in the clothes acquired by the acquisition unit 30 and the radiant heat. As mentioned above, the risk of heat stroke increases with the information of temperature rise, humidity rise, and solar radiation intensity (see Non-Patent Document 1). The heat index calculation unit 31 uses the temperature and humidity inside the clothes measured by the clothes 1 with a sensor worn by the user, and the radiant heat temperature (also referred to as the solar heat temperature) by the following equation (2). The heat index for each user (hereinafter referred to as "individual heat index") is calculated.

Individual heat index [° C] = A x clothing temperature [° C] + B x clothing wet-bulb equivalent temperature [° C] + C x solar heat temperature [° C] ... (2)
However, the coefficients A, B, and C represent weighting coefficients such that A + B + C = 1.

In the above equation (2), the wet-bulb equivalent temperature inside the clothes is the temperature measured by the wet-bulb, which is calculated based on the relative humidity inside the clothes and the temperature inside the clothes measured by the clothes 1 with a sensor. .. The heat index calculation unit 31 can calculate the wet-bulb globe-equivalent temperature in clothes by using, for example, a known approximate formula according to the following formula (3).

Wet-bulb temperature in clothes [° C] = (Temperature in clothes [° C] + 10 [° C]) x (Humidity in clothes [%] / 250 + 0.615) -10 ° C ... (3)

The alarm unit 32 issues an alarm when the individual heat index calculated by the heat index calculation unit 31 exceeds a preset threshold value. For example, 28 [° C.] is adopted as the threshold value, and an alarm is issued when the individual heat index exceeds 28 ° C. Further, for example, a multi-step threshold value can be set. Specifically, 25 [° C.], 28 [° C.], and 31 [° C.] may be used as threshold values to issue an alarm according to the risk of heat stroke in these three stages.

Further, the alarm unit 32 can generate and issue an alarm in a form that can be sensed by the user, such as sound, vibration, and light.

It has a program storage area. Further, the auxiliary storage device 105 has an area in which a preset threshold value of the heat index is stored. The auxiliary storage device 105 realizes the storage unit 34 described with reference to FIG. Further, for example, it may have a backup area for backing up the above-mentioned data, programs, and the like.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the following description, the same components as those in the first embodiment described above will be designated by the same reference numerals, and the description thereof will be omitted.

The sensor-equipped garment 1 according to the first embodiment has described the case where the sensor device 1A is attached to the outside of the garment body 20. On the other hand, in the second embodiment, the sensor device 1A is attached to the inside of the garment body 20.

More specifically, the sensor device 1A is attached with the second wall member 10b of the housing 10 facing the inside of the garment body 20. Further, the region of the outer surface of the second wall member 10b where the radiant heat sensor 12 is provided is exposed to the outside of the garment main body 20 from the opening 2h.

As shown in FIGS. 9 and 10, the garment body 20 includes a fabric that is attached around the opening 2h of the back surface 2b to form a pocket 2c that houses the sensor device 1A. For the pocket 2c, for example, a mesh fabric can be used. A mesh fabric is a fabric that is more breathable and quick-drying. For example, a synthetic fiber fabric having holes that can be visually confirmed can be mentioned.

Further, the pocket 2c has a size corresponding to the outer shape of the sensor device 1A. In the pocket 2c, when the sensor device 1A is inserted into the pocket 2c, the area where the black portion of the radiant heat sensor 12 is provided coincides with the opening 2h of the clothes 2 on the outer surface of the second wall member 10b.

The black portion exposed from the opening 2h absorbs radiant heat from the outside such as solar radiation, and the radiant heat sensor 12 measures the radiant heat from the outside.

On the other hand, the outer surface of the first wall member 10a including the region where the temperature / humidity sensor 11 is provided is between the back surface 2b of the garment 2 and the surface of the user's skin B via the pocket 2c formed of the mesh fabric. It touches the space S in the clothes formed in. The temperature / humidity sensor 11 measures the humidity and temperature inside the clothes through the pockets 2c of the mesh fabric.

As described above, according to the second embodiment, since the sensor device 1A can be inserted into the inner pocket 2c provided on the back surface 2b of the garment 2, the sensor device 1A can be more easily attached and detached. Further, it is possible to prevent the sensor device 1A from coming off from the clothes 2 due to an impact from the outside or the like.

Further, according to the second embodiment, since the pocket 2c uses a mesh fabric having high breathability and quick-drying property, the temperature / humidity sensor 11 can better measure the environment inside the clothes.

Further, according to the second embodiment, since the sensor device 1A is attached to the inside of the clothes 2, the entire sensor device 1A is not exposed to the outside, which is more preferable in terms of appearance.

Further, according to the second embodiment, in the sensor device 1A, only the black portion of the radiant heat sensor 12 is directly exposed to the sunlight, and the entire housing 10 is not directly exposed to the sunlight. Therefore, it is possible to prevent the temperature of the housing 10 from rising due to sunlight. As a result, the temperature / humidity sensor 11 can measure the temperature inside the clothes with higher accuracy.

In the embodiment described, the first wall member 10a and the second wall member 10b of the housing 10 face each other, the temperature / humidity sensor 11 is supported by the first wall member 10a, and the radiant heat sensor 12 is the second wall. The case where it is supported by a member has been described. However, the first wall member 10a and the second wall member 10b are not limited to the case where they are arranged to face each other in the housing 10. For example, the position of the second wall member 10a can be arbitrarily determined so that the temperature / humidity sensor 11 is provided on the lower side or the upper side of the housing 10 (with respect to the ground). Further, the temperature / humidity sensor 11 can be configured to be supported at an arbitrary position on the second wall member 10b.

Further, in the described embodiment, the case where the physical condition management device 3 calculates the heat index of the user has been described. However, the heat index calculation unit 31 may have a configuration calculated by the sensor device 1A. In this case, the physical condition management device 3 is realized by, for example, a wearable terminal such as a smartphone or a smart watch carried by the user, and notifies the user of an alarm or a calculated personal heat index.

Further, in the described embodiment, the case where the sensor device 1A has the temperature sensor 11a, the humidity sensor 11b, and the radiant heat sensor 12 has been described. However, in addition to these sensors, the sensor device 1A further includes sensors that measure the amount of activity of the user, such as a 3-axis accelerometer, a pulse rate monitor, a heart rate monitor, an electrocardiograph, a respiratory sensor, and a sensor that combines these. You may have it.

In this case, the alarm unit 32 can change the threshold value and the content of the alarm according to the amount of activity of the user indicated by the acceleration of the user, the pulse, and the like. Therefore, the activity status of the user can be reflected in the individual heat index calculated for each user, and the degree of risk according to the heat index for each user can be presented more accurately.

Further, in the described embodiment, the case where the physical condition management device 3 calculates the individual heat index based on the temperature and humidity in the clothes measured by the clothes 1 with the sensor and the radiant heat has been described. However, the physical condition management device 3 acquires data on the external environment such as weather information at the user's position based on the user's position information, and obtains data on the temperature and humidity in clothes, radiant heat, and the external environment. The heat index for each individual may be calculated based on the above. In this case, for example, the sensor device 1A is provided with a GPS receiver.

Although the embodiments of the garment with a sensor, the physical condition management system, and the physical condition management program of the present invention have been described above, the present invention is not limited to the described embodiments, and the scope of the invention described in the claims. It is possible to make various modifications that can be assumed by those skilled in the art.
